Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a large-sized enclosure that has a simple structure, uses a minimum number of members effectively, and can be made extremely strong.

[Conventional technology and its problems]

The applicant has already developed various types of large construction boards that serve as structural materials from the viewpoint of workability, strength, affordability, etc., and has constructed large-scale enclosures using the large construction boards. ing. However, even if these large construction boards can be made stronger by making the metal thicker and have a larger cross-sectional shape, they have the disadvantage of relatively high component costs, and it is difficult to make a large outer wall that is even stronger using a minimum number of materials. Physical development is required.

[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 large elongated building made of metal, which has a vertical part formed from the outer end, a horizontal edge formed inward from the upper ends of both vertical parts, and a folded edge formed above the inner end of the horizontal edge. A cap material having a gate-shaped cross section is fitted and secured by placing a longitudinally elongated T-shaped reinforcing material between the opposing horizontal edge, folded edge, and vertical portion. Alternatively, a long reinforcing material may be polymerized and fixed to form a relatively high inclined part facing outward on both sides of the bottom part, and an upper part may be formed outward from the upper ends of both inclined parts. A metal product having a vertical part formed from both outer ends of the upper part, a horizontal edge formed inward from the upper end of the both vertical parts, and a folded edge formed above the inner end of the horizontal edge. A long large construction board is attached to the board, and a long T-shaped reinforcing member is sandwiched in the longitudinal direction between the opposing horizontal edge, folded edge, and vertical part to form a gate-shaped cross section. By forming a large-sized enclosure into which a cap material is fitted and fixed, the entire large-sized enclosure can be made extremely strong with a simple structure and a minimum number of members can be used effectively, thus solving the above-mentioned problems.

〔Example〕

First, the first invention will be explained.

1 to 5 show the first invention. In particular, in the first invention, the bottom part 1 of the large construction board A
The present invention is characterized in that a bulging strip 7 is formed on the surface, but the other components are common to the first invention and the second invention.

The length is 0.5m to about 0.8m, and the width is about 1m to 1.5m.
On both sides of the flat bottom portion 1, inclined portions 2, 2 are formed which face outward and have a relatively high height. Approximately flat upper portions 3, 3 are formed outside the upper ends of the inclined portions 2, 2. In the embodiment shown in the drawings, the upper parts 3, 3 are formed with a slightly upward slope toward the outside, but the invention is not limited thereto. 4,

Horizontal edges 5, 5 are formed inwardly from the upper ends of the vertical portions 4, 4, and folded edges 6, 6 are formed outwardly from the inner ends of the horizontal edges 5, 5. Its horizontal edge 5 may also be formed with a slight slope.

The large construction board A, which is composed of the bottom part 1 inclined part 2, 2 upper part 3, 3 vertical part 4, 4 horizontal edge 5, 5 folded edge 6, 6, is one large long piece. The metal plates are integrally formed using a roll forming machine. The bulging portion 14, which will be described later, is formed using a press mold after the roll forming process. In the middle of the bottom part 1, an upwardly bulging strip 7 extends along its longitudinal direction.
(see drawing) or formed with multiple bends (first
(See Figures 2 and 5).

The large construction board A is placed on the support 9, and at this time, as shown on the left side of FIG. The T-shaped reinforcement 10 is inserted between the folded edge 6 and then the adjacent large building board A is mounted on the support 9 and the T-shaped reinforcement 10 is inserted between its horizontal edge 5 and the folded edge 6. is held. Here, adjacent large building boards A, A are installed together, and then a T-shaped reinforcing material 10 is sandwiched between the horizontal edges 5, 5, the folded edges 6, 6, and the vertical parts 4, 4. Sometimes.
A large long metal cap member B having a gate-shaped cross section and having hanging portions 12, 12 formed on both sides of the substantially flat upper surface portion 11 is attached to the opposing large construction boards A, A. It is fitted onto the folded edges 6, 6, its both hanging portions 12, 12 are folded downward and crimped onto the lower surface of the horizontal edges 5, 5, and the vertical portions 4, 4 are fitted onto the bolt/nut 13. These steps are successively repeated to form a large enclosure as shown in FIG. 1.

(for example, approximately 50 cm to approximately 1
m) is formed to bulge upward perpendicular to the longitudinal direction. 15 is a beam material, and 16 is a base.

Next, the second invention will be explained based on FIG. 6. 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 long metal reinforcing member 8 is polymerized and fixed to the entire bottom part 1 of the large building board A according to the second invention or between the bottom part 2 and the lower side of both inclined parts 2, 2 (Fig. 6). reference).

The construction of the outer enclosure according to the second invention is the same as that of the first invention.

〔Effect of the invention〕

In the invention set forth in claim 1 (first invention), sloped portions 2, 2 having a relatively high height facing outward and upward are formed on both sides of the bottom portion 1 with the bulging strip 7 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 part 3, and inward from the upper ends of both vertical parts 4, 4. horizontal edges 5, 5 are formed on both horizontal edges 5, 5;
Large long architectural boards A, A made of metal with folded edges 6, 6 formed above the inner ends thereof are installed, and the opposing horizontal edges 5, 5 and folded edges 6, 6 are vertically aligned. A simple structure is achieved by using a large outer envelope in which a cap material B having a gate-shaped cross section is fitted and fixed in such a manner that a longitudinally elongated T-shaped reinforcing material 10 is sandwiched between the parts 4 and 4. This has the effect of converting the minimum number of members into effective mechanical strength and making the entire large enclosure extremely strong.

To explain this effect in detail, a long T-shaped reinforcing member 10 is clamped and fixed on the upper surface side of the large-scale enclosure of the present invention with the neutral axis (neutral plane) as the boundary, and the neutral axis (neutral plane) On the lower surface of the neutral plane, a bulging strip 7 is provided in the middle of the bottom 1, so that the part farthest from the neutral axis (neutral plane) where the maximum bending stress is applied is reinforced, and the part that is most distant from the neutral axis (neutral plane), where the maximum bending stress is applied, is ), the maximum compressive bending stress and the maximum tensile bending stress can be significantly increased, and the large construction board A that constitutes the large outer body.
By having the T-shaped reinforcing material 10 and the bulging strips 7, the large building board A can be made even stronger as a structural material even if the entire cross section of the board A is not made of thick material. That is,
The large building board A constituting the large enclosure has sloped parts 2, 2 with relatively high heights facing outward and upward on both sides of the bottom part 1, and an upper part extending outward from the upper ends of both sloped parts 2, 2. 3, 3, vertical portions 4, 4 are formed from both outer ends, horizontal edges 5, 5 are formed inward from the upper ends of both vertical portions 4, 4, and both horizontal edges 5 are formed. ,5
It is made of a longitudinally elongated metal plate with folded edges 6, 6 formed above the inner end of the plate, and this alone has a large section modulus and can increase mechanical strength. Furthermore, the parts that are the most distant from the neutral axis (neutral plane) where the bending stress is applied are reinforced, and as a result, the large building board A itself can fulfill its role as a structural material.
It is also possible to further widen the spacing between the beams 15, 15, and by doing so, it is possible to have a simple roof structure that eliminates the need for a main building, etc., and therefore, it is possible to significantly reduce construction costs. be able to.

In particular, the present invention has the advantage that even if the number of components is reduced, the entire large enclosure can be made extremely strong. That is, providing the bulging strip 7 in the middle of the bottom 1 can be done only by roll forming without increasing the amount of any parts, and can be done at extremely low cost.

Moreover, if a self-propelled fitting device is used to clamp and fix the T-shaped reinforcing member 10 and fit the cap material B during construction, the workability can be greatly increased.

Next, in the invention of claim 2 (second invention), instead of the bulging strip 7 of the first invention, a long reinforcing material 8 is polymerized and fixed to the bottom 1 of the bottom part 1. It is possible to increase the mechanical strength of the large construction board A without changing its cross-sectional shape and board thickness. In other words, by not changing the cross-sectional shape and thickness of the large construction board A, it is possible to make it strong and provide good support by providing a reinforcing material 8, which is an appropriate separate member, for a certain mass-produced product. Become.

Furthermore, the reinforcing material 8 polymerized and fixed to the bottom part 1 of the large construction board A has a strength that corresponds to the site (withstands vertical loads such as snowfall) even if the material of the large construction board A has a constant thickness and a constant cross section. ) can be selected and installed as appropriate.

Note that the strength is the same as in the first invention.
