Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to large building boards that can be made extremely strong and serve as structural members.

[Conventional technology and its problems]

Specifically, the applicant has developed various large-sized construction boards that themselves serve as structural materials from the viewpoints of workability, strength, price, etc. However, even if the metal plate can be made stronger by making it thicker and larger in cross-sectional shape, the cost of the parts will be relatively high, and it is difficult to develop a strong large-scale construction board using the minimum amount of parts. It is strongly requested.

[Means to solve the problem]

Therefore, in the present invention, a relatively high inclined part facing outward and upward is formed on both sides of a bottom part with a bulging strip provided in the middle, an upper part is formed outwardly from the upper ends of both the inclined parts, and both sides of the upper part are formed. A vertical part is formed from the outer end, a horizontal edge is formed inward from the upper end of both the vertical parts, and a folded edge is formed above the inner end of the both horizontal edges, and these are made of metal and are connected in the longitudinal direction. A large construction board with a long U-shaped reinforcing material fixed in the longitudinal direction between the lower surface of the upper part, the outer surface of the vertical part, the horizontal edge, and the folded edge; A relatively high sloped portion facing outward and upward is formed on both sides of the bottom portion to which reinforcing material is polymerized and fixed, an upper portion is formed outside the upper ends of both sloped portions, and a vertical portion is formed from both outer ends of the upper portion. forming a horizontal edge inwardly from the upper ends of both the vertical parts, forming a folded edge above the inner ends of the both horizontal edges, these being made of metal and elongated in the longitudinal direction,
By creating a large construction board with a long U-shaped reinforcing material fixed in the longitudinal direction between the lower surface of the upper part, the outer surface of the vertical part, the horizontal edge, and the folded edge, the metal plate does not have to be made into a thick material. Both serve as strong structural materials and solve the above problems.

The bulging portion 10, which will be described later, is formed using a press mold after roll forming. A long metal U-shaped reinforcing member 7 is fixed in the longitudinal direction between the lower surface of the upper part 3, the outer surface of the vertical part 4, and the horizontal edge 5 and folded edge 6.
That is, the bottom side and vertical portion of the U-shaped reinforcing member 7 are superimposed and fixed (spot welding, etc.) on the lower surface of the upper part 3 and the outer surface of the vertical portion 4, and the upper side of the U-shaped reinforcing member 7 is connected to the horizontal edge 5. It is clamped and fixed between the folded edge 6. The U-shaped reinforcement members 7, 7 are symmetrically provided on the right side of the large building board A. its bottom 1

The support body 14 and the upper part 3 are fixed with bolts, nuts, etc., and the large architectural boards A and A are attached to each other, and then the horizontal edges 5, 5 and the folded edges 6 of the adjacent large architectural boards A and A are attached. , 6, and both hanging portions 12, 12 of the cap material B are folded downward and crimped onto the lower surfaces of the horizontal edges 5, 5, and these steps are repeated sequentially to form the cap material B as shown in FIG. A large outer enclosure will be constructed with mushrooms. Further, the vertical portions 4, 4 of the adjacent large building boards A, A may be fixed with bolts and nuts (see the dotted lines in Figure 5).

Next, the second invention will be explained based on FIG. 2. Since the second invention also includes the above-described first invention as a part of its constituent elements, the same reference numerals are given to these parts.

A reinforcing material 9 is polymerized and fixed to the entire bottom portion 1 of the large-sized construction board A according to the second invention, or between the bottom portion 2 and the lower side of both inclined portions 2, 2 (see FIG. 2).

The construction of the outer enclosure according to the second invention is the same as that of the first invention (see FIG. 2).

〔Effect of the invention〕

In the invention of claim 1 (first invention), inclined parts 2, 2 having a relatively high height facing outward and upward are formed on both sides of the bottom part 1 with the bulging strip 8 provided in the middle. Upper parts 3, 3 are formed outside the upper ends of both inclined parts 2, 2, vertical parts 4, 4 are formed from both outer ends of the upper parts 3, 3, and vertical parts 4, 4 are formed from the upper ends of both vertical parts 4, 4. Horizontal edges 5, 5 are formed inward, folded edges 6, 6 are formed above the inner ends of both horizontal edges 5, 5, and these are elongated in the longitudinal direction. Outer surface and horizontal edge 5 and folded edge 6 of section 4
By forming a large construction board with a long U-shaped reinforcing member 7 fixed in the longitudinal direction between the board and the board, it has the effect of acting as a strong structural member.

To explain the effect in detail, large-sized construction board A of the present invention
On the upper surface side of the neutral axis (neutral plane), there is a long U-shaped reinforcement in the longitudinal direction between the lower surface of the upper part 3, the outer surface of the vertical part 4, the horizontal edge 5, and the folded edge 6. Material 7
is fixed, and on the lower side of the neutral axis (neutral plane), a bulging strip 8 is formed in the middle of the bottom 1, so that the maximum bending stress is applied from the neutral axis (neutral plane) to the The parts separated from each other are reinforced, and the maximum compressive bending stress and maximum tensile bending stress against external force (vertical load) can be significantly increased, and the mechanical strength of the large building board A can be further strengthened.
That is, on both sides of the bottom part 1, inclined parts 2, 2 with a relatively high height are formed outwardly upward, and upper parts 3, 3 are formed outwardly from the upper ends of both the inclined parts 2, 2, and from the outer ends thereof, upper parts 3, 3 are formed. forming vertical portions 4, 4; both vertical portions 4, 4;
A large building made of a longitudinally elongated metal plate, which has horizontal edges 5, 5 formed inward from the upper end, and folded edges 6, 6 formed above the inner ends of both horizontal edges 5, 5. Mechanical strength can be increased by using only the material of plate A, but in addition to this strength, we have reinforced the part farthest from the neutral axis (neutral plane) where the maximum bending stress is applied. Therefore, the large building board A itself can more than fulfill its role as a structural material, making it possible to further widen the spacing between the beams 13, 13, and by doing so, the main building etc. This eliminates the need for a simple roof structure, which not only improves workability but also significantly reduces construction costs.

In addition, the upper side of the U-shaped reinforcing material 7 is clamped and fixed between the horizontal edge 5 and the folded edge 6, so that the top part of the large construction board A can be reinforced and it is difficult to peel off. It can stick.

Further, in the first invention, the bulging strip 8 can be provided in the middle of the bottom portion 1 by only roll forming without increasing the amount of any parts, which can be done at extremely low cost.

In addition, in the invention of claim 2 (second invention), a long reinforcing material 9 is polymerized and fixed in place of the bulging strip 8 of the bottom part 1 in the first invention, so that the large building board Even if the material A has a constant thickness and a constant cross section, it can be installed by selecting a material with strength appropriate to the site (against vertical loads such as snowfall).

In addition, the maximum compressive bending stress and maximum tensile bending stress against external force (vertical load) can be significantly increased, and the mechanical strength of the large building board A can be strengthened. Similar to invention.
