DESCRIPTION
DOUBLE-FLOOR MEMBER
TECHNICAL FIELD
[0001] The present invention relates to a double-floor member, such as
a floor panel or a frame, installed in a free access floor laid on a floor
portion of a room such as a data center in which IT devices such as
servers are received.
BACKGROUND ART
[0002] In recent years, a large amount of data has been handled by IT
devices such as servers as a sophisticated information society comes.
For this reason, there are many cases in which a lot of IT devices are
installed in a data center, a server room, or the like and are collectively
managed.
[0003] Figs. 35 to 37 are views illustrating a data center 1 in the related
art. As illustrated in Figs. 35 and 36, a free access floor 12 having a
double-floor structure is formed on a floor portion of a room of the data
center 1 and a plurality of floor panels 3 are laid so as to form the floor
face of the free access floor 12 (for example, see Patent Document 1).
[0004] As illustrated in Fig. 36, the floor panels 3 are horizontally
supported at a predetermined height by support legs 7 standing on a
concrete foundation floor face 5 and are laid side by side so as to form
the floor face of the room of the data center 1. Accordingly, pipes and
1
23502807.1
CA 2971986 2018-11-13
wires are provided in a space between the floor panels 3 and the
foundation floor face 5 that is present below the floor panels 3.
[0005] Further, a frame 2 standing on the foundation floor face 5 is
disposed at a place where the floor panels 3 are not laid in the data
center 1, and a plurality of server racks 10 on which servers are
mounted on racks of the respective stages are placed side by side on
the frame 2 so as to be adjacent to each other (for example, see Patent
Document 2).
[0006] The frame 2 is formed of a combination of a plurality of L-shaped
steel members (angle members 4) and a plate-like steel sheet (upper
plate member 6), and is produced so as to have the same height as the
floor face of the free access floor 12 (the upper surface of the floor panel
3) and so as to correspond to the sizes (width and depth) of the server
racks 10. Furthermore, leg parts of the frame 2 are fixed to the
foundation floor face 5 by anchor bolts 11.
[0007] Moreover, male screw portions of fixing bolts 8 are inserted into
through-holes that are formed in each of a bottom plate portion 10a
forming the bottom of the server rack 10 and the upper plate member 6
forming the upper surface of the frame 2.
[0008] Further, the lower surface of a head portion of the fixing bolt 8 is
engaged with the upper surface of the bottom plate portion 10a of the
server rack 10, and the upper surface (the upper surface in Fig. 36) of a
fixing nut 9 fastened to the tip portion of the male screw portion of the
fixing bolt 8 is engaged with the lower surface of the upper plate
member 6.
2
23502807.1
CA 2971986 2018-11-13
[0009] The server racks 10 and the frame 2 are connected to each other
by the fixing bolts 8 and the fixing nuts 9 as described above so that the
server racks 10 are not separated upward from the upper surface of the
frame 2 and do not fall down.
[0010] Since the server racks 10 are disposed on the frame 2, the floor
panels 3 do not receive the load of the server racks 10 and the load of
the server racks 10 can be directly applied to the foundation floor face 5
through the frame 2. Accordingly, it is possible to improve a load
bearing property about the load of the server rack 10 in comparison with
a case in which the server racks 10 are placed on the upper surfaces of
the floor panels 3.
[0011] In addition, since the server racks 10 are disposed on the frame 2,
it is possible to prevent the server racks 10 from falling down at the time
of the occurrence of an earthquake or the like and to improve the
levelness of the server rack 10 in comparison with a case in which the
server racks 10 are placed on the floor panels 3.

SUMMARY OF THE INVENTION
PROBLEM TO BE SOLVED BY THE INVENTION
[0013] However, since the sizes (width and depth) of the server rack 10
3
23502807.1
CA 2971986 2018-11-13
vary for each product in the data center 1 in the related art, the positions
of through-holes, which are formed in the bottom plate portion 10a of the
server rack 10 and are used to connect the server rack to the frame 2 in
order to prevent the server rack 10 from falling down, also vary for each
product.
[0014] For this reason, a plurality of through-holes 2a, which are used to
connect the server rack 10, need to be formed in the upper plate
member 6 of the frame 2 in advance as illustrated in Fig. 37 while
assuming the horizontal positions of the through-holes formed in the
bottom plate portion 10a of the server rack 10.
[0015] Further, when it is assumed that the horizontal positions of the
through-holes formed in the bottom plate portion 10a of the server rack
are disposed at the peripheral portion of the upper plate member 6
supported by the angle members 4, the plurality of through-holes 2a,
which are used to connect the server rack 10, need to be formed in
advance so as to pass through both the upper plate member 6 and the
angle members 4.
[0016] Furthermore, whenever the through-holes formed in the bottom
plate portion 10a of the server rack 10 are formed at positions that are
not assumed in advance, the plurality of through-holes 2a, which are
used to connect the server rack 10, need to be formed in the upper plate
member 6 of the frame 2 or both the upper plate member 6 and the angle
members 4.
[0017] Since the through-holes 2a need to be formed in the frame 2
according to various types of server racks 10 as described above, there
4
23502807.1
CA 2971986 2018-11-13
are problems in that the cost required for the work for the installation of
the server rack 10 increases and construction efficiency is reduced.
[0018] Accordingly, the invention has been made in consideration of the
abovennentioned problems and an object of the invention is to provide a
double-floor member that can prevent an increase in the cost required
for work for the installation of a server rack and prevent the reduction of
construction efficiency.

MODE(S) FOR CARRYING OUT THE INVENTION
[0029] Double-floor members according to embodiments of the invention
will be described below in detail with reference to the drawings.
Figs. 1 to 13 are views illustrating a floor panel 20 (a double-floor
member) according to a first embodiment of the invention.
[0030] As illustrated in Figs. 1 to 4, the floor panel 20 according to this
embodiment mainly includes a panel body 21, a tile 22 that is attached
to the upper surface of the panel body 21, first guide rails 24 that are
fixed to the upper surface of the tile 22, slide members 27 (first
connecting member) that are disposed so as to be movable in the first
guide rails 24 in a longitudinal direction, and the like.
[0031] The panel body 21 is a die-cast product that uses an aluminum
alloy as a material thereof, and includes a flat plate portion 21a that
forms an upper surface of the panel body 21 and a plurality of ribs 21b
23502807.1
CA 2971986 2018-11-13
that are integrally formed on the back surface of the flat plate portion
21a (see Fig. 2).
[0032] The plurality of ribs 21b of the panel body 21 protrude from the
back surface of the flat plate portion 21a toward the lower side of the
floor (in a downward direction in Figs. 5 and 7), and are formed in a
lattice shape so as to extend along the horizontal surface of the flat
plate portion 21a in both a longitudinal direction and a lateral direction
(a vertical direction and a horizontal direction in Fig. 2). Since the
plurality of ribs 21b are formed on the panel body 21, the strength of the
panel body 21 is improved.
[0033] Further, 16 through-holes 21c, which pass through the flat plate
portion 21a in the thickness direction of the flat plate portion 21a (a
vertical direction in Fig. 3), are formed side by side at predetermined
intervals at positions where the ribs 21b are not formed on the back
surface of the flat plate portion 21a of the panel body 21 (see Figs. 1
and 2).
[0034] Furthermore, the tile 22, such as a vinyl chloride-based P-tile or a
HPL (high-pressure laminate) tile, is attached to the upper surface of the
flat plate portion 21a of the panel body 21. While the tile 22 is attached
to the flat plate portion 21a of the panel body 21, outer peripheral
portions of the floor panel 20 forming the respective sides are cut
together. For this reason, the respective outer peripheral portions of the
floor panels 20 are formed with high dimensional accuracy (for example,
0.1 mm or less).
[0035] Further, 16 through-holes 22a, which pass through the tile 22 in
11
23502807.1
CA 2971986 2018-11-13
the thickness direction of the tile 22 (a vertical direction in Fig. 6), are
formed at the positions, which correspond to the through-holes 21c
formed in the flat plate portion 21a of the panel body 21, on the tile 22 so
as to communicate with the through-holes 21c (see Fig. 1).
[0036] Furthermore, steel or the like is used as the material of each of
the first guide rails 24, and each of the first guide rails 24 is formed so
as to have a C-shaped cross-sectional shape perpendicular to the
longitudinal direction thereof (see Fig. 8). A bottom plate portion 24a
opposite to an opening of the C-shaped first guide rail comes into
contact with and is fixed to the upper surface of the tile 22 so that the
opening of the C-shaped first guide rail 24 faces the upper side (the C
shape is rotated in a counterclockwise direction by 900 ).
[0037] Moreover, as illustrated in Fig. 1, two first guide rails 24 are
disposed on the upper surface of the tile 22 to extend in the horizontal
direction in Fig. 1 to a substantially left end potion of the upper surface
of the tile 22 from a substantially right end portion thereof in Fig. 1 so
that the longitudinal directions of the two first guide rails 24 are parallel
to each other.
[0038] Further, through-holes 24b, which pass through the bottom plate
portion 24a in the thickness direction of the bottom plate portion 24a,
are formed in the bottom plate portion 24a (see Figs. 6 and 8) of each of
the first guide rails 24 that comes into contact with the upper surface of
the tile 22. The first guide rails 24 are disposed so that the
through-holes 24b communicate with the through-holes 21c of the panel
body 21 and the through-holes 22a of the tile 22.
12
23502807.1
CA 2971986 2018-11-13
[0039] Furthermore, as illustrated in Fig. 6, the lower surfaces of head
portions 29a of bolts 29 come into contact with and are engaged with the
upper surface of the inner peripheral portion of the bottom plate portion
24a of the first guide rail 24, and male screw portions 29b of the bolts 29
are inserted into the through-holes 24b of the first guide rail 24, the
through-holes 22a of the tile 22, and the through-holes 21c of the panel
body 21.
[0040] Moreover, flat plate members 25 are disposed at the tip portions
of the longest ribs 21b, which protrude from the back surface of the flat
plate portion 21a toward the lower side of the floor (in a downward
direction in Fig. 6), among the plurality of ribs 21b of the panel body 21
so that the upper surfaces of the flat plate members 25 come into
contact with the tip portions of the longest ribs. Female screw holes
25a, which pass through the plate member 25 in a thickness direction (a
vertical direction in Fig. 6), are formed in each plate member 25.
[0041] Further, a tip portion of the male screw portion 29b of the bolt 29,
which is inserted into the through-hole 24b of the first guide rail 24, the
through-hole 22a of the tile 22, and the through-hole 21c of the panel
body 21 and protrudes downward in Fig. 6, is fastened to the female
screw hole 25a of the plate member 25.
[0042] Since the lower surfaces of the head portions 29a of the bolts 29
are engaged with the upper surface of the bottom plate portion 24a of
the first guide rail 24 and the upper surface of the plate member 25
fastened to the tip portion of the male screw portion 29b of the bolt 29 is
engaged with the lower surfaces of the ribs 21b of the panel body 21 as
13
23502807.1
CA 2971986 2018-11-13
described above, the first guide rail 24 is fixed to the tile 22 so as not to
be separated upward from the upper surface of the tile 22.
[0043] Further, steel or the like is used as the material of each of the
slide members 27, and each of the slide members 27 is formed so as to
have a U-shaped cross-sectional shape perpendicular to the
longitudinal direction thereof (see Fig. 8). Each of the slide members 27
is disposed in the first guide rail 24 in an inverted U-shape so that an
opening of the U-shaped slide member faces the lower side in Fig. 8.
[0044] Furthermore, each of the slide members 27 is formed so that the
height position of a lower surface 27b (see Figs. 6 and 8) of an upper
plate portion 27a opposite to the opening of the U-shaped slide member
27 is higher than the height position of the upper surface of the head
portion 29a of the bolt 29.
[0045] In addition, the slide member 27 is formed so that the width (the
length in the horizontal direction in Fig. 8) of the opening of the
U-shaped slide member 27 is larger than the diameter (the length in the
horizontal direction in Fig. 8) of the head portion 29a of the bolt 29.
[0046] For this reason, when the slide member 27 is moved in the
longitudinal direction of the first guide rail 24, the slide member 27 can
be freely moved from the right end portion of the first guide rail 24 in Fig.
1 to the left end portion thereof in Fig. 1 without coming into contact with
the head portion 29a of the bolt 29.
[0047] Further, the width (the length in the horizontal direction in Fig. 8)
of the upper plate portion 27a of the slide member 27 is larger than the
width (the length in the horizontal direction in Fig. 8) of the opening of
14
23502807.1
CA 2971986 2018-11-13
the first guide rail 24 opened to the upper side.
[0048] For this reason, the upward movement of the slide member 27 in
Fig. 8 is limited by the engagement between the slide member 27 and
the first guide rail 24. Accordingly, the slide member 27 is formed so as
not to get out of (be separated from) the first guide rail 24 through the
opening of the first guide rail 24 even when the slide member 27 is
pulled upward in Fig. 8.
[0049] Furthermore, three female screw holes 27c, which pass through
the upper plate portion 27a in a thickness direction of the upper plate
portion 27a (a vertical direction in Fig. 8), are formed in the upper plate
portion 27a of the slide member 27 so as to be adjacent to each other in
the longitudinal direction of the slide member 27 (a horizontal direction
in Fig. 6).
[0050] Further, as illustrated in Fig. 8, the three female screw holes 27c
of the upper plate portion 27a of the slide member 27 are adapted so
that a male screw portion 26b of a fixing bolt 26, which is inserted
through the opening of the first guide rail 24 opened to the upper side in
Fig. 8, can be fastened to the female screw hoie 27c.
[0051] As illustrated in Figs 9 and 10, server racks 100 (cases), which
include leg parts 100a mounted on bottom plate portions 100b thereof,
are placed on the upper surface of the floor panel 20. Furthermore, four
corners of the floor panel 20 are supported by support legs 109,
respectively.
[0052] A through-hole 20a (see Figs. 1 and 2), which pass through the
floor panel 20 in a direction perpendicular to the plane of Fig. 1, and a
23502807.1
CA 2971986 2018-11-13
stepped face, which is slightly recessed from the upper surface of the
floor panel 20 toward the lower side ot the floor (in a downward direction
in Fig. 9) so as to surround the through-hole 20a, are formed at each of
the four corners of the floor panel 20.
[0053] Head portions of bolts (not illustrated), which are inserted into
the through-holes 20a from the upper surface of the floor panel 20, are
engaged with the stepped faces and male screw portions of the bolts are
fastened to female screw holes (not illustrated) that are formed on the
support surfaces of the support legs 109 (see Fig. 9). Accordingly, the
four corners of the floor panel 20 are fixed to the support legs 109,
respectively.
[0054] Further, the support legs 109 have a load bearing property so as
to be capable of bearing the load of the server racks 100, and leg
portions of the support legs 109 are fixed to a foundation floor face 5 by
anchor bolts 115 as illustrated in Figs. 9 and 10.
[0055] Furthermore, through-holes 100c, which pass through a bottom
plate portion 100b of the server rack 100 in a thickness direction (a
vertical direction in Fig. 11) of the bottom plate portion 100b, are formed
in the bottom plate portion 100b (see Fig. 11) of the server rack 100.
[0056] Incidentally, a required number of first guide rails 24 are fixed to
the floor panel 20 illustrated in Fig. 9. For this reason, the floor panel 20
to which two first guide rails 24 are fixed as in Fig. 1 and the floor panel
20 to which only one first guide rail 24 is fixed are illustrated in Fig. 9.
[0057] As illustrated in Fig. 11, the lower surface of a head portion 26a
of the fixing bolt 26 comes into contact with and is engaged with the
16
23502807.1
CA 2971986 2018-11-13
upper surface of the bottom plate portion 100b of the server rack 100,
and a tip portion of the male screw portion 26b of the fixing bolt 26 is
inserted into the through-hole 100c of the server rack 100 and the
opening of the first guide rail 24 and is fastened to the female screw
hole 27c formed in the upper plate portion 27a of the slide member 27
(see Fig. 8).
[0058] Since the lower surface of the head portion 26a of the fixing bolt
26 is engaged with the upper surface of the bottom plate portion 100b of
the server rack 100 and the male screw portion 26b of the fixing bolt 26
is fastened to the slide member 27, which is provided so as not to get
out of the first guide rail 24 upward, as described above, the server rack
100 is connected to the floor panel 20 by the fixing bolts 26 so as not to
be separated upward from the upper surface of the floor panel 20 and
fall down.
[0059] Further, when the horizontal position of the slide members 27 in
Fig. 1 does not correspond to the through-hole 100c of the server rack
100 connected to the floor panel 20, it is possible to align the position of
the slide member 27 with the position of the through-hole 100c of the
server rack 100 by moving the slide member 27 in the longitudinal
direction of the first guide rail 24.
[0060] Furthermore, in Fig. 1, the fixing bolt 26, which connects the
server rack 100 to the floor panel 20, is fastened to the middle female
screw hole 27c of the slide member 27 in Fig. 1 among the three female
screw holes 27c (see Fig. 6) formed in the slide member 27.
[0061] However, when the slide members 27 are moved along the first
17
23502807.1
CA 2971986 2018-11-13
guide rails 24 and the fixing bolts 26 are fastened to the middle female
screw holes 27c of the slide members 27 in Fig. 1 at the positions of the
right end portions of the first guide rails 24 in Fig. 1 so that the server
rack 100 and the floor panel 20 are connected to each other by the fixing
bolts 26, there is a concern that the right end portion of the slide
member 27 in the longitudinal direction in Fig. 1 may protrude to the
outside of the first guide rail 24 in the longitudinal direction.
[0062] For this reason, for example, when stoppers, which prevent the
slide member 27 from protruding to the outside of the first guide rail 24
in the longitudinal direction, are provided at both longitudinal end
portions of the first guide rail 24, the middle female screw hole 27c of
the slide member 27 in Fig. 1 cannot be aligned with the position of the
right end portion of the first guide rail 24 in Fig. 1.
[0063] In such a case, when the fixing bolt 26 is fastened to the
rightmost female screw hole 27c in Fig. 6 among the three female screw
holes 27c (see Fig. 6) formed in the slide member 27 as illustrated in Fig.
12, it is possible to prevent the right end portion of the slide member 27
in the longitudinal direction in Fig. 12 from protruding to the outside of
the first guide rail 24 in the longitudinal direction.
[0064] That is, when the rightmost female screw hole 27c of the slide
member 27 in Fig. 1 is aligned with the position of the right end portion
of the first guide rail 24 in Fig. 1 even when the above-mentioned
stoppers are provided at both longitudinal end portions of the first guide
rail 24, the server rack 100 and the floor panel 20 can be connected to
each other by the fixing bolts 26.
18
23502807.1
CA 2971986 2018-11-13
[0065] The same is applied to a case in which the slide members 27 are
moved along the first guide rails 24 and the server rack 100 and the floor
panel 20 are connected to each other by the fixing bolts 26 at the
positions of the left end portions of the first guide rails 24 in Fig. 1.
[0066] That is, when the fixing bolt 26 is fastened to the leftmost female
screw hole 27c in Fig. 1 among the three female screw holes 27c (see
Fig. 6) formed in the slide member 27, it is possible to prevent the left
end portion of the slide member 27 in the longitudinal direction in Fig. 1
from protruding to the outside of the first guide rail 24 in the longitudinal
direction.
[0067] Further, when the vertical positions of the slide members 27 in
Fig. 1 do not correspond to the through-holes 100c of the server rack
100 connected to the floor panel 20, it is possible to change the vertical
positions of the slide members 27 in Fig. 1 by changing the fixing
positions of the first guide rails 24 on the upper surface of the tile 22 to
other positions at which the through-holes 22a are formed.
[0068] For example, in Fig. 1, the two first guide rails 24 are fixed to the
positions of the through-holes 22a that are formed side by side along
two lower rows, which extend in the horizontal direction in Fig. 1, on the
upper surface of the tile 22. However, in order to align the vertical
positions of the slide members 27 in Fig. 1 with the positions of the
through-holes 100c of the server rack 100, it is possible to change the
fixing positions of the two first guide rails 24 to the positions of the
through-holes 22a that are formed side by side along two middle rows,
which extend in the horizontal direction in Fig. 1, in the vertical direction
19
23502807.1
CA 2971986 2018-11-13
in Fig. 1 on the upper surface of the tile 22 as illustrated in Fig. 13.
[0069] As described above, the sizes (width and depth) of the server
rack 100 vary for each product. Accordingly, even when the positions of
the through-holes 100c of the server rack 100 vary for each product, it is
possible to align the horizontal positions of the slide members 27 to
which the fixing bolts 26 are fastened with the horizontal positions of the
through-holes 100c of the server rack 100 by changing the fixing
positions of the first guide rails 24 or moving the slide members 27 in the
longitudinal directions of the first guide rails 24.
[0070] Accordingly, if the floor panel 20 according to this embodiment is
used in work for the installation of the server rack 100, a plurality of
through-holes, which are used to fix the server rack 100, do not need to
be formed in the floor panel 20 in advance while assuming the horizontal
positions of the through-holes 100c varying for each server rack 100 as
a product.
[0071] Further, if the floor panel 20 according to this embodiment is
used in the work for the installation of the server rack 100,
through-holes, which are used to fix the server rack 100, do not need to
be formed in the floor panel 20 whenever the horizontal positions of the
through-holes 100c varying for each server rack 100 as a product are
present at positions that cannot be assumed in advance.
[0072] Accordingly, if the floor panel 20 according to this embodiment is
used in the work for the installation of the server rack 100, it is possible
to prevent an increase in the cost required for the work for the
installation of the server rack 100 and to prevent the reduction of
23502807.1
CA 2971986 2018-11-13
construction efficiency.
[0073] Figs. 14 to 26 are views illustrating a floor panel 30 (double-floor
member) according to a second embodiment of the invention.
[0074] A floor panel 30 according to this embodiment is different from
the floor panel 20 according to the first embodiment in that the floor
panel 30 includes second guide rails 34 and slide members 37 (second
connecting member) in addition to the first guide rails 24 and the slide
members 27 as illustrated in Fig. 14. Other structures of the floor panel
30 are the same as those of the floor panel 20 according to the first
embodiment.
[0075] That is, in the floor panel 20 according to the first embodiment,
as illustrated in Fig. 1, two first guide rails 24 extending in the horizontal
direction in Fig. 1 are fixed to the upper surface of the tile 22 and it is
possible to align the horizontal positions of the slide members 27 with
the horizontal positions of the through-holes 100c of the server rack 100
by moving the slide members 27 in the longitudinal directions of the first
guide rails 24.
[0076] Meanwhile, in the floor panel 30 according to this embodiment,
as illustrated in Fig. 14, two first guide rails 24 extending in a horizontal
direction in Fig. 14 are fixed to the upper surface of the tile 22 and both
longitudinal end portions of two second guide rails 34 extending in a
vertical direction in Fig. 14 are fixed to the upper surfaces of the first
guide rails 24 (see Fig. 16) so that the second guide rails 34 are
orthogonal to the two first guide rails 24 (are bridged between the first
guide rails 24).
21
23502807.1
CA 2971986 2018-11-13
[0077] Further, when the slide members 27 are moved in the longitudinal
directions of the first guide rails 24, the second guide rails 34 can be
moved in the horizontal direction in Fig. 14. The slide members 37 can
be moved in the longitudinal direction of the second guide rails 34.
[0078] For this reason, when the slide members 37 are moved along the
longitudinal directions of the first and second guide rails 24 and 34 in
the horizontal direction and the vertical direction in Fig. 14, the
horizontal positions of the slide members 37 can be aligned with the
horizontal positions of the through-holes 100c of the server rack 100.
[0079] Through-holes 34b (see Fig. 18), which pass through a bottom
plate portion 34a in a thickness direction of the bottom plate portion 34a,
are formed in the bottom plate portion 34a (see Fig. 20), which comes
into contact with the upper surfaces of the first guide rails 24, at both
longitudinal end portions of the second guide rails 34, and each of the
second guide rails 34 is disposed so that the through-holes 34b
communicate with the middle female screw holes 27c in the horizontal
direction in Fig. 18 among the three female screw holes 27c of each
slide member 27.
[0080] Further, as illustrated in Fig. 20, the lower surfaces of head
=
portions 39a of bolts 39 come into contact with and are engaged with the
upper surface of the bottom plate portion 34a of the second guide rail 34,
and male screw portions of the bolts 39 are fastened to the female screw
holes 27c of the slide members 27. Accordingly, both longitudinal end
portions of the second guide rail 34 are connected to the slide members
27 that are movable along the first guide rails 24.
22
23502807.1
CA 2971986 2018-11-13
[0081] Furthermore, steel or the like is used as the material of each of
the slide members 37, and each of the slide members 37 is formed so as
to have a U-shaped cross-sectional shape perpendicular to the
longitudinal direction thereof (see Fig. 18). Each of the slide members
37 is disposed in the second guide rail 34 in an inverted U shape so that
an opening of the U-shaped slide member faces the lower side in Fig.
18.
[0082] Moreover, each of the slide members 37 is formed so that the
height position of a lower surface 37b (see Figs. 18 and 20) of an upper
plate portion 37a opposite to the opening of the U-shaped slide member
37 is higher than the height position of the upper surface of the head
portion 39a of the bolt 39.
[0083] In addition, the slide member 37 is formed so that the width (the
length in the horizontal direction in Fig. 18) of the opening of the
U-shaped slide member 37 is larger than the diameter (the length in the
horizontal direction in Fig. 18) of the head portion 39a of the bolt 39.
[0084] For this reason, when the slide member 37 is moved in the
longitudinal direction of the second guide rails 34, the slide member 37
can be freely moved from the upper end portion of the second guide rail
34 in Fig. 14 to the lower end portion thereof in Fig. 14 without coming
into contact with the head portion 39a of the bolt 39.
[0085] Further, the width (the length in the horizontal direction in Fig.
18) of the upper plate portion 37a of the slide member 37 is larger than
the width (the length in the horizontal direction in Fig. 18) of the opening
of the second guide rail 34 opened to the upper side.
23
23502807.1
CA 2971986 2018-11-13
[0086] For this reason, the upward movement of the slide member 37 in
Fig. 18 is limited by the engagement between the slide member 37 and
the second guide rails 34. Accordingly, the slide member 37 is formed
so as not to get out of (be separated from) the second guide rail 34
through the opening of the second guide rail 34 even when the slide
member 37 is pulled upward in Fig. 18.
[0087] Furthermore, three female screw holes 37c, which pass through
the upper plate portion 37a in a thickness direction of the upper plate
portion 37a (a vertical direction in Fig. 20), are formed in the upper plate
portion 37a of the slide member 37 side by side in the longitudinal
direction of the slide member 37 (a horizontal direction in Fig. 20).
[0088] Further, as illustrated in Fig. 18, each of the three female screw
holes 37c of the upper plate portion 37a of the slide member 37 is
formed so that a male screw portion 26b of a fixing bolt 26, which is
inserted through the opening of the second guide rail 34 opened to the
upper side in Fig. 18, can be fastened to the female screw hole 37c.
[0089] As illustrated in Figs. 21 and 22, server racks 100, which include
leg parts 100a mounted on bottom plate portions 100b thereof, are
placed on the upper surface of the floor panel 30. Furthermore,
through-holes 100c, which pass through the bottom plate portion 100b in
a thickness direction of the bottom plate portion 100b (a vertical
direction in Fig. 23), are formed in the bottom plate portion 100b (see
Fig. 23) of the server rack 100.
[0090] Moreover, similar to the floor panel 20 according to the first
embodiment, bolts (not illustrated) are inserted into through-holes 30a
24
23502807.1
CA 2971986 2018-11-13
(see Fig. 14) formed at four corners of the floor panel 30, head portions
of the bolts are engaged with stepped faces formed on the upper surface
of the floor panel 30, and male screw portions of the bolts are fastened
to female screw holes (not illustrated) formed on the support surfaces of
support legs 109 (see Fig. 21). Accordingly, the four corners of the floor
panel 30 are fixed to the support legs 109, respectively.
[0091] Further, the support legs 109 are fixed to a foundation floor face
by anchor bolts 115 as illustrated in Figs. 21 and 22.
[0092] Incidentally, a required number of second guide rails 34 are fixed
to the floor panel 30 illustrated in Fig. 21. For this reason, the floor panel
30 to which two second guide rails 34 are fixed as in Fig. 14 and the
floor panel 30 to which only one second guide rail 34 is fixed are
illustrated in Fig. 21.
[0093] As illustrated in Fig. 23, the lower surface of a head portion 26a
of the fixing bolt 26 comes into contact with and is engaged with the
upper surface of the bottom plate portion 100b of the server rack 100,
and a tip of the male screw portion 26b of the fixing bolt 26 is inserted
into the through-hole 100c of the bottom plate portion 100b of the server
rack 100 and the opening of the second guide rail 34 and is fastened to
the female screw hole 37c formed in the upper plate portion 37a of the
slide member 37.
[0094] Since the lower surface of the head portion 26a of the fixing bolt
26 is engaged with the upper surface of the bottom plate portion 100b of
the server rack 100 and the male screw portion 26b of the fixing bolt 26
is fastened to the slide member 37, which is formed so as not to get out
23502807.1
CA 2971986 2018-11-13
of the second guide rail 34 upward, as described above, the server rack
100 is connected to the floor panel 30 by the fixing bolts 26 so as not to
be separated upward from the upper surface of the floor panel 30 and
fall down.
[0095] Accordingly, when the horizontal and vertical positions of the
slide member 37 in Fig. 14 do not correspond to the through-hole 100c
of the server rack 100 to be connected, it is possible to move the second
guide rail 34 in the horizontal direction in Fig. 14 by moving the slide
members 27 in the longitudinal directions of the first guide rails 24 and
to align the position of the slide member 37 with the position of the
through-hole 100c of the server rack 100 to be connected by moving the
slide members 37 in the longitudinal directions of the second guide rails
34.
[0096] That is, the floor panel 30 is configured so that the slide members
37 can be moved in the longitudinal directions of the first and second
guide rails 24 and 34. Accordingly, when the horizontal positions of the
through-holes 100c of the bottom plate portion 100b of the server rack
100 are disposed in a range between the two first guide rails 24, it is
possible to align the horizontal positions of the slide members 37 with
the horizontal positions of the through-holes 100c by moving the slide
members 37 in the longitudinal directions of the first and second guide
rails 24 and 34.
[0097] Furthermore, in Fig. 14, the fixing bolt 26, which connects the
server rack 100 to the floor panel 30, is fastened to the middle female
screw hole 37c in Fig. 14 among the three female screw holes 37c
26
23502807.1
CA 2971986 2018-11-13
formed in the slide member 37 (see Figs. 20 and 24).
[0098] However, when the slide members 37 are moved in the
longitudinal directions of the second guide rails 34 and the fixing bolts
26 are fastened to the middle female screw holes 37c in Fig. 14 at the
positions of the lower end portions of the second guide rails 34 in Fig. 14
such that the server rack 100 and the floor panel 30 are connected to
each other by the fixing bolts 26, there is a concern that the lower end
portion of the slide member 37 in the longitudinal direction in Fig. 14
may protrude to the outside of the second guide rail 34 in the
longitudinal direction.
[0099] For this reason, for example, when stoppers, which prevent the
slide member 37 from protruding to the outside of the second guide rail
34 in the longitudinal direction, are provided at both longitudinal end
portions of the second guide rail 34, the middle female screw hole 37c of
the slide member 37 in Fig. 14 cannot be aligned with the position of the
lower end portion of the second guide rail 34 in Fig. 14.
[0100] In such a case, when the fixing bolt 26 is fastened to the
lowermost female screw hole 37c (see Fig. 20) in Fig. 24 among the
three female screw holes 37c formed in the slide member 37 as
illustrated in Fig. 24, it is possible to prevent the lower end portion of the
slide member 37 in the longitudinal direction in Fig. 24 from protruding
to the outside of the second guide rail 34 in the longitudinal direction.
[0101] That is, when the lowermost female screw hole 37c of the slide
member 37 in Fig. 14 is aligned with the position of the lower end portion
of the second guide rail 34 in Fig. 14 even when the above-mentioned
27
23502807.1
CA 2971986 2018-11-13
stoppers are provided at both longitudinal end portions of the second
guide rail 34, the server rack 100 and the floor panel 30 can be
connected to each other by the fixing bolts 26.
[0102] The same is applied to a case where the slide members 37 are
moved along the second guide rails 34 and the server rack 100 and the
floor panel 30 are connected to each other by the fixing bolts 26 at the
positions of the upper end portions of the second guide rails 34 in Fig.
14.
[0103] That is, when the fixing bolt 26 is fastened to the uppermost
female screw hole 37c in Fig. 14 among the three female screw holes
37c (see Fig. 20) formed in the slide member 37, it is possible to prevent
the upper end portion of the slide member 37 in the longitudinal
direction in Fig. 14 from protruding to the outside of the second guide
rail 34 in the longitudinal direction.
[0104] Further, when the vertical positions of the through-holes 100c of
the server rack 100 in Fig. 14 are not formed in a range between the two
first guide rails 24, it is possible to change a range, in which the slide
members 37 can be moved in the vertical direction in Fig. 14, by
changing the fixing positions of the first guide rails 24 on the upper
surface of the tile 22 to other positions at which the through-holes 22a
are formed.
[0105] For example, in Fig. 14, the two first guide rails 24 are fixed to
the positions of the through-holes 22a that are formed along two lower
rows in Fig. 14 on the upper surface of the tile 22. However, in order to
align the vertical positions of the slide members 37 in Fig. 14 with the
28
23502807.1
CA 2971986 2018-11-13
positions of the through-holes 100c of the server rack 100 as illustrated
in Fig. 25, it is possible to change the fixing positions of the two first
guide rails 24 to the positions of the through-holes 22a that are formed
along two middle rows in Fig. 25 on the upper surface of the tile 22.
[0106] Furthermore, as illustrated in Fig. 26, the plurality of
through-holes 22a and 21c of the tile 22 and the panel body 21, which
are formed at intervals, are formed so as to be separated from each
other in the vertical direction in Fig. 26 by a length L. Moreover, the
through-holes 22a and 21c, which are formed at the outermost
peripheral portion of the floor panel 30 in Fig. 26, are formed so as to be
separated from the sides of the floor panel 30 in the vertical direction in
Fig. 26 by a length L/2.
[0107] For this reason, when the slide members 37 are moved to the
outside of the through-holes 22a and 21c, which are formed at the
outermost peripheral portion of the floor panel 30, the second guide rails
34 can be disposed over the floor panels 30 and 30 adjacent to each
other as illustrated in Fig. 26.
[0108] That is, when one first guide rail 24 is fixed to the through-holes
22a and 21c that are formed at the outermost peripheral portion of each
of the floor panels 30 and 30 adjacent to each other, a vertical distance
between the first guide rails 24 and 24 fixed to the respective floor
panels 30 and 30 adjacent to each other is L (the sum of L/2 and L/2).
[0109] Accordingly, since the vertical distance between the first guide
rails 24 and 24 fixed to the respective floor panels 30 and 30 adjacent to
each other is not L or more, the slide members 37 can also be moved to
29
23502807.1
CA 2971986 2018-11-13
the peripheral edge portions of the floor panel 30 when both end
portions of the second guide rails 34 are connected to the upper
surfaces of the two first guide rails 24 over the floor panels 30 and 30.
[0110] As described above, the sizes (width and depth) of the server
rack 100 vary for each product. Accordingly, even when the positions of
the through-holes 100c of the server rack 100 vary for each product, it is
possible to align the horizontal positions of the slide members 37 to
which the fixing bolts 26 are fastened with the horizontal positions of the
through-holes 100c of the server rack 100 by changing the fixing
positions of the first guide rails 24, moving the slide members 27 in the
longitudinal directions of the first guide rails 24, or moving the slide
members 37 in the longitudinal directions of the second guide rails 34.
[0111] That is, since the positions of the slide members 37 are moved so
as to be aligned with the horizontal positions of the through-holes 100c
of the server rack 100 in the floor panel 30 according to this embodiment,
the server rack 100 and the floor panel 30 can be connected to each
other at an arbitrary position in the horizontal direction.
[0112] Accordingly, if the floor panel 30 according to this embodiment is
used in work for the installation of the server rack 100, a plurality of
through-holes, which are used to fix the server rack 100, do not need to
be formed in the floor panel 30 in advance while assuming the horizontal
positions of the through-holes 100c that vary for each server rack 100 as
a product.
[0113] Further, if the floor panel 30 according to this embodiment is
used in the work for the installation of the server rack 100,
23502807.1
CA 2971986 2018-11-13
through-holes, which are used to fix the server rack 1 00, do not need to
be formed in the floor panel 30 whenever the horizontal positions of the
through-holes 100c varying for each server rack 100 as a product are
present at positions that cannot be assumed in advance.
[0114] Accordingly, even when the floor panel 30 according to this
embodiment is used in the work for the installation of the server rack
100, it is possible to prevent an increase in the cost required for the
work for the installation of the server rack 100 and to prevent the
reduction of construction efficiency as in the floor panel 20 according to
the first embodiment.
[0115] Fig. 27 is a view illustrating a floor panel 40 (double-floor
member) according to a third embodiment of the invention.
[0116] The floor panel 40 according to this embodiment is different from
the floor panel 20 according to the first embodiment in that the length of
a first guide rail 44 is shorter than the length of the first guide rail 24 of
the floor panel 20 according to the first embodiment as illustrated in Fig.
27. Other structures of the floor panel 40 are the same as those of the
floor panel 20 according to the first embodiment.
[0117] That is, in the floor panel 20 according to the first embodiment,
as illustrated in Fig. 1, the first guide rails 24 are disposed so as to
extend in the horizontal direction in Fig. 1 to the substantially left end
potion of the upper surface of the tile 22 from the substantially right end
portion thereof in Fig. 1.
[0118] Meanwhile, in the floor panel 40 according to this embodiment,
as illustrated in Fig. 27, each of the first guide rail 44 is formed to have a
31
23502807.1
CA 2971986 2018-11-13
length of about 1/3 of the length of the first guide rail 24 of the floor
panel 20 so that both end portions of the first guide rail 44 are disposed
at the positions of through-holes 22a and 21c adjacent to each other in a
horizontal direction in Fig. 27.
[0119] Even when the floor panel 40 according to this embodiment is
used, it is possible to obtain the same effects as the floor panel 20
according to the first embodiment.
[0120] Fig. 28 is a view illustrating a floor panel 50 (double-floor
member) according to a fourth embodiment of the invention.
[0121] The floor panel 50 according to this embodiment is different from
the floor panel 20 according to the first embodiment in that groove rails
51c are formed in a panel body 51 and slide members 27 (first
connecting member) can be moved in the longitudinal directions of the
groove rails 51c (a direction perpendicular to the plane of Fig. 28) as
illustrated in Fig. 28. Other structures of the floor panel 50 are the same
as those of the floor panel 20 according to the first embodiment.
[0122] That is, in the floor panel 20 according to the first embodiment,
as illustrated in Fig. 8, the first guide rail 24 is fixed to the upper
surface
of the tile 22, the slide member 27 is disposed in the first guide rail 24,
and it is possible to align the position of the slide member 27 with the
position of the through-hole 100c of the server rack 100 by moving the

[0171] Moreover, the first guide rails 24, the slide members 27, the
second guide rails 34, and the slide members 37 are disposed on the
panel body 21 in the floor panels 20 and 30 according to the first and
second embodiments, but may be disposed on the frame 2 (double-floor
member) used in the data center 1 in the related art (see Fig. 36).
43
23502807.1
CA 2971986 2018-11-13
[0172] Even when the frame 2 is used instead of the floor panels 20 and
30 according to the first and second embodiments as described above, it
is possible to obtain the same effects as the floor panels 20 and 30
according to the first and second embodiments.
[0173] Further, in the floor panels 50 and 55 according to the fourth and
fifth embodiments, the groove rails 51c are formed on the upper surface
of the floor panels 50 and 55 and the slide members 27, the second
guide rails 34, and the slide members 37 are disposed on the panel body

according to the fourth and fifth embodiments.
[0175] Furthermore, the two first guide rails 24 are fixed to the upper
surface of the floor panel 20 according to the first embodiment. However,
the number of the first guide rails 24 fixed to the upper surface of the
floor panel 20 does not need to be limited to two, and one first guide
rails 24 may be fixed or three or more first guide rails 24 may be fixed.
[0176] Moreover, the tile 22, such as a vinyl chloride-based P-tile or a
HPL (high-pressure laminate) tile, is attached to the upper surface of the
flat plate portion 21a of the panel body 21. However, the tile 22 does
not need to be limited to these hard tiles, and for example, a soft sheet,
44
23502807.1
CA 2971986 2018-11-13
such as a vinyl chloride sheet, may be attached or a tile carpet may be
attached. Further, nothing may be attached to the upper surface of the
flat plate portion 21a of the panel body 21.
[0177] Further, in the floor panel 20 according to the first embodiment,
each of the opening shape of the through-hole 21c of the panel body 21
and the opening shape of the through-hole 22a of the tile 22 is a circular
shape as illustrated in Fig. 1. However, long holes having a length in the
vertical direction in Fig. 1 may be formed in the range of positions where
the ribs 21b are not formed on the back surface of the flat plate portion
21a of the panel body 21.
[0178] When each of the opening shape of the through-hole 21c of the
panel body 21 and the opening shape of the through-hole 22a of the tile
22 is formed into the shape of a long hole having a length in the vertical
direction in Fig. 1, the first guide rail 24 can be disposed so as to be
inclined with respect to the side of the tile 22. When the first guide rails
24 are fixed to the upper surface of the tile 22, construction is easy.
[0179] Furthermore, in the floor panel 40 according to the third
embodiment, as illustrated in Fig. 27, each of the first guide rails 44 is
formed so as to have a length of about 1/3 of the length of the first guide
rail 24 of the floor panel 20 according to the first embodiment. However,
the length of the first guide rail 44 may be further formed to be short so
that the first guide rail is locally disposed.
[0180] Moreover, in the floor panels 20 and 30 according to the first and
second embodiments, as illustrated in Figs. 1 and 14, the male screw
portions 29b of the bolts 29 are inserted into the through-holes 22a and
23502807.1
CA 2971986 2018-11-13
21c to fix the first guide rails 24. However, through-holes 22a and 21c
that are formed at positions where the first guide rails 24 are not
disposed (the through-holes 22a and 21c that are not used to fix the first
guide rails 24) are not closed.
[0181] For this reason, in the floor panels 20 and 30 according to the
first and second embodiments, the through-holes 22a and 21c that are
not used to fix the first guide rails 24 (the through-holes 22a and 21c
formed side by side along two upper rows in Figs. 1 and 14 that extend
in the horizontal direction in Figs. 1 and 14) may be closed by, for
example, caps or the like.
[0182] It is possible to prevent air from leaking from the upper surfaces
of the floor panels 20 and 30 to the lower surfaces thereof and from the
lower surfaces thereof to the upper surfaces thereof through the
through-holes 22a and 21c by closing the through-holes 22a and 21c,
which are not used to fix the first guide rails 24, by caps or the like as
described above.
