CONSTRUCTION BOARD
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to construction boards used
for walls and ceilings of buildings, and partitions of
prefabricated buildings, and more particularly to construction
boards capable of making the construction of walls simple and
stable.
Description of the Prior Art
Generally, walls, ceilings and partitions of general
buildings and prefabricated buildings are constructed by
modules, so as to make their construction and assembly
convenient. Such a module comprises a frame and a pair of
asbestos or gypsum boards mounted to opposite surfaces of the
frame. The boards are ones already treated for providing a
soundproof effect and a thermal insulation effect. The frame
comprises metal bars or wood bars so constructed that nails
can be driven in them.
On boards of such a conventional module, however, there
is no indication making it possible to find board portions
corresponding the frame in which nails can be driven.
As a result, the conventional module has an inconvenience
-~ 2~92970
that the position of the frame should be previously confirmed,
where fasteners such as nail, screws and staples are desired
to be driven in the boards. Even skilled persons are
difficult to find correctly the position of frame.
Consequently, the nailed condition and nailing work may be
poor. In this case, the boards may be damaged or have
unnecessary holes due to the poor nailing work.
Such problems are remarkable where a plurality of
overlapping boards are provided for increasing the soundproof
effect and the thermal insulation effect. In particular,
coupling of the multi-layered boards by the nailing work may
be poor, thereby causing the overall construction work to be
poor. Where the workers cut the modules to have desired
length or width, the cutting work should be manually carried
out and requires a lot of time. As a result, there are
problems of a decrease in work efficiency and an increase in
labor and cost.
SUMMARY OF THE INVENTION
Therefore, the present invent;on has been made in view of
the above-mentioned problems encountered in the prior art and
an object of the invention is to provide a construction board
including capable of making the construction and assembling
5 works easy and simple by using nailing portions formed on the

:-`` 2~92~70 ::
construction board and constituted by longitudinal and lateral
partition lines, multi-section points, or uniformly spaced
characters, and of being easily cut to a desired size by using
perforated lines formed on the construction board.
In accordance with the present invention1 this object can
be accomPlished by providing a construction board attached at
its inner surface to a frame having longitudinal and lateral
section parts, said construction board having at its outer
surface a plurality of nailing portions corresponding to the
section parts of the frame, said nailing portions comprising~
at least one longitudinal thick partition line adapted to sect
longitudinally the construction board into equal longitudinal
section parts; at least one lateral thick partition line
adapted to sect laterally the construction board into equal
16 lateral section parts; an edge line extending along a
peripheral edge of the construction board; a plùrality of
thick multi-section points formed along each of said thick
partition lines and said edge line; at least one longitudinal
fine partition line adapted to sect longitudinally each of
said longitudinal section parts into equal longitudinal sub~
section parts; at least one lateral fine partition line
adapted to sect laterally each of said lateral section parts
into equal lateral sub-section parts; and a plurality of fine
multi-section points formed along each of said fine partition

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 and 2, there is illustrated a
construction module in accordance with a basic embodiment of
the present invention. As shown in FIGS. 1 and 2, the
construction ~odule comprises a frame 1 constructed by ~ ;
connecting wood bars or metal bars and a construction board 2
-4~
` -'-` 20929~
fixedly attached to one of opposite surfaces of the frame 1.
Of course, another construction board having the same
construction as the construction board 2 may be attached to
the other surface of the frame 1, although not shown.
In accordance with the present invention, the
construction board 2 includes at its outer surface a
longitudinal bisection thick partition line 3 and three
:- :~:
lateral quadrisection thick partition lines 4. Although the
thick partition lines 3 and 4 are shown as one and three,
respectively, respective numbers thereof may be increased,
depending on the size of the construction module. The
- construction board 2 also includes at its edges 5 a thick line
6 having the same width as the thick partition lines 3 and 4.
Each of the thick lines 3, 4 and 6 has a plurality of points
7 at positions defined by uniformly multi-sectioning it.
These partition lines 3 and 4, the line 6, and the multi-
section points 7 serve as nailing portions 8. Also, each of
the partition lines 3 and 4 has a specific nailing mark 9.
On the outer surface of the construction board 2, two
longitudinal trisection fine partition lines 10 and five
lateral six-section fine partition lines 11. Although the
fine partition lines 10 and 11 are shown as two and five,
respectively, respective numbers thereof may be increased,
depending on the size of the construction module. Each of the
fine lines 10 and 11 has a plurality of points 12 at positions
-5-
, ~
, ~
2092~70
defined by uniformly multi-sectioning it. These multi-section
points 12 serve as nailing portions 13.
Although the construction board 2 has all of the lateral
thick partition lines ~ and 4, the thick lines 6, the thick
points 7, the fine partition lines 10 and 11, and the fine
points 12, in the embodiment illustrated in FIGS. 1 and 2, it
may have only thick ones or fine ones.
When a construction board 2 is to be coupled to the frame
1 or to another construction board 2, or construction boards
2 coupled to frames 1 are overlapped with and coupled to each
other, the worker confirms the nailing portions 8 constituted
by the partition lines 3, 4, 10 and 11, the line B, and the
points 7 and 12 of the board or boards 2 and drives nails,
screws or staples in the nailing portions 8.
Referring to FIGS. 3 and 4, there is illustrated another
embodiment of the present invention. In accordance with this
embodiment, the board 2 includes only longitudinal and lateral
multi-section lines 14 and 15. In this embodiment, proper
positions on the multi-section lines 14 and 15 are used as
nailing portions. Also, the nailing portions may be provided
by cross points 16 between the multi-section lines 14 and 15.
FIGS. 5 to 8 illustrate another embodiment of the present
invention. In accordance with the present invention, the
board 2 includes points 17, numerics 18, characters 19 and a
pattern 20 indicative of a trademark at positions defined by
--6--
~92970
multi-sectioning the board 2. These points 17, numerics 18,
characters 19 and pattern 20 serve as nailing portions.
In the illustrated embodiments, the board 2 is sectioned
into equal multi-section parts such as two parts, three parts,
four parts or six parts, by partition lines or points. ~ ;
However, the number of multi-section parts may be varied,
depending on various sizes of modules, for example, inch-
dimensional modules having sizes such as 3'x 6', 3'x 7', 3'x
8' and 4'x 8' and meter-dimensional modules.
Referring to FIG. 9, there is illustrated still another
embodiment of the present invention. In accordance with the
present invention, the board 2 includes a plurality of
uniformly spaced longitudinal perforated lines 21 and a
plurality of uniformly spaced lateral perforated lines 22, as
well as the thick partition lines 3 and 4, and fine partition
lines 10 and 11. By these perforated lines 21 and 22, the
board 2 can be cut to a desired size, if desired.
As apParent from the above description, the present
invention provides a construction board including various
partition lines and points serving as nailing portions in
which fasteners such as nails, screws and staples are driven,
when the board is fixedly attached to a frame. Even unskilled
persons can perform easily the nailing work and the selection
of nailing positions, by simply selecting desired nailing
positions from the nail;ng portions. Also, the assembling
-7-
2092370
work for multi-layered boards can be madc easily and simply by
utilizing the nailing portions of the boards. Accordingly,
the nailing work can be achieved easily and correctly.
The constru~tion board of the present invention requires
no effort for finding nailins positions, thereby enabling the
constructing and working time and the cost to be greatly
reduced. In particular, the construction board can be easily
cut to a desired size, by virtue of the perforated lines 21
and 22 of FIG. 9. Where the construction board has a nailing
portion provided by a trademark, it has not only an
advertisement effect therefor, but also effects of making the
assembling and constructing works therefor convenient and
correct.
Although the preferred embodiments of the invention have
been disclosed for illustrative purposes, those skilled in the
art will appreciate that various modifications, additions and
substitutions are possible, without departing from the scope
and spirit of the invention as disclosed in the accompanying
claims.
