"INSULATION MEANS FOR CORRUGATED METAL BUILDINGS"
BACKGROUND OF THE INVENTION
This invention relates to new and useful improve-
ments in means for insulating corrugated metal buildings.
Such buildings are extremely difficult to insulate
due to the difficulty in holding the insulation in place and
to ensure that the insulation molds substantially to the con-
figuration of the metal walls and ceiling. These metal walls
and ceilings are usually corrugated and comprise a plurality
of troughs and crests being formed by adjacent sections of
metal bolted together to form the errected structure.
SUMMARY OF T~E INVENTION
The present invention overcomes these disadvantages
by providing means to hold insulation in position and to ensure
that it molds itself substantially to the configuration of the
surface and one aspect of the invention comprises means for in-
sulating corrugated metal building structures and the like, in
which said structures include a plurality of elongated metal
channels having side walls and extending side flanges-formed on
said side walls and bolted together through adjacent flanges to
form a corrugated section comprising a plurality of alternating
troughs and crests with the distal ends of the attaching bolts
extending through the bolted flanges at the bases of the
troughs; said means comprising in combination spacer posts at-
tached to the distal ends of the bolts and extending perpendi-
cularly of the corrugated section, flexible insulation engaged

over the distal ends of the spacer posts and running substan-
tially at right angles to the run of the troughs, and means
engaging the distal ends of the spacer posts to retain the in-
sulation thereon said means running substantially parallel with
the troughs, said flexible insulation following substantially
the transverse contour of the corrugated section.
Another aspect of the invention consists of providing
means whereby a corrugated building can be readily insulated
and is economical in structure, simple in construction and
otherwise well suited to the purpose for which it is designed.
With the foregoing in view, and other advantages as
will become apparent to those skilled in the art to which this
invention relates as this specification proceeds, the invention
is herein described by reference to the accompanying drawings
forming a part hereof, which includes a description of the pre-
ferred typical embodiment of the principles of the present in-
vention, in which:

DETAILED DESCRIPTION
Proceeding therefore to describe the invention in de-
tail, reference should first be made to Figure 1 which shows a
part of a building collectively designated 10 made from corru-
gated metal sections 11 and including side walls 12, a curved
roof 13 and a front wall 14 within which doors 15 may be placed.
The individual corrugated sections are shown clearly
in Figure 3 and it will be noted that each section is in the
form of a channel consisting of a base 16, upwardly and outward-
ly inclining side walls 17 and offstanding outer flanges 18 ex- -
tending from the upper sides of the side walls and running
parallel to the base 16. Adjacent channels are bolted together
by the overlapping flanges 18 by means of nut and bolt assemb-
~lies l9 with the inner ends 20 of the bolts extending inwardly
of the building and being situated in longitudinally extending
troughs 21 formed alternately with the crests 22 of the formed
corrugated section~ it being understood that the crests com-
prise the bases 16 of the individual channels.
It will also be observed that in general, the troughs

and crests 21 and 22 extend vertically of the walls 12 and
transversely of the longitudinal axis of the building,
through the roof portion 13.
This gives an extremely strong and rigid self-sup-
porting building which is often used for manufacturing, tem-
porary office buildings, storage facilities and the like. It
will of course be appreciated that it is difficult to insu-
late such structures particularly with batt type insulation
in which it is desired that the batt follows the contour of
the corrugated section, particularly the corrugated section
of the roof portion 13.
Means are provided to enable such insulation to be
secured to the inner surface or underside of the roof and to
the inner surface of the side walls and end walls of such
structures. Said means takes the form of a spacer post col-
lectively designated 23 and preferably made of synthetic plas-
tic in order to insulate the inner ends and to provide a
thermal barrier between the metal forming the structure and
the inner ends of the posts thereby preventing frost, conden-
sation and the like from forming thereon. However it will be
appreciated that under certain circumstances, such as when
the insulation i5 primarily for the exclusion of heat, then
such posts can be made of metal if desired.
The posts 23, in this embodiment, take the form of
an inner end portion 24, the outer configuration of which is
hexagonal as shown in Figure 5 so that a wrench can be engaged
thereon. A concentric bore 25 is formed within this end por-

tion 24 and ls screw threaded so that it may be screw thread-
ably engaged over the inner end portion 20 of the nut and bolt
assembly 19 as clearly shown in Figure 7.
The central portion 26 of the post preferably tapers
as illustrated and then terminates in an inner end portion 27
which is screw threaded as clearly shown and is provided with
a pointed or sharpened distal end ~8, the purpose of which
will hereinafter be described. A nut type washer 29 may be
screw threadably engaged over the portion 27 after installation
or, alternatively, a conventional push on type friction washer
(not illustrated) may be utilized.
The posts are engaged over the ends of bolts 20 after
the structure has been erected so that they extend in spaced
relationship from the troughs 21 of the structure. Flexible
insulation 30 is then engaged over the ends of these spacer
posts, the pointed ends 28 of which facilitate the piercing of
the insulation. This insulation ~ay be in batt form or, pre-
ferably, batt form with at least one surface (the outer surface)
being covered by paper, plastic or the like in order to retain
the insulatlon therein. The batts run perpendicular to the
direction of the troughs 21 and by pushing it upwardly upon
the posts, the insulation molds itself to the transverse pro-
file of the surface of the corrugated section against which it
is engaged as clearly shown in Figure 3.
Means are provided to hold the batts in position,
said means taking the form of metal, wooden or plastic strips

which are apertured and engage over the posts and run longi-
tudinally of the troughs 21 as clearly shown in Figures 2 and
3. Figure 6 shows a metal or plastic strip 31 apertured as
at 32 for engagement over the ends of posts 23 and it will
be observed that it is slightly curved and designed specifi-
cally to follow the curvature of the roof section 13. How-
ever thin wooden straps can be used if desired as shown in
Figure 2 and these will either bend slightly due to the flex-
ibility thereof or, alternatively, can be short enough that
they do not need to bend but will still hold the insulation
in position.
These strips are held in position either by the a-
forementioned flat washer type screw threaded components 29
or by the engagement of push type friction washers (not illus-
trated) upon the distal end portions of the spacer posts 23.
It is of course appreciated that the batts are engaged in side
by side relationship so that the entire inner surface of the
structure may be insulated and held in position readily and
easily.
Since various modifications can be made in my inven-
tion~as hereinabove described, and many apparently widely dif-
ferent embodiments of same made within the spirit and scope of
the claims without departing from such spirit and scope, it is
intended that all matter contained in the accompanying specifi-
cation shall be interpreted as illustrative only and not in a
limiting sense.
