Abstract

PROBLEM TO BE SOLVED: To form a large space and secure a sufficient strength by bending crests and valleys of a folding metal sheet to form an arched body and fixing respective corners of the inside face and tightening metal fixtures of two corners separated from each other at every other corner or two or more corners by bracings. SOLUTION: A plurality of folding metal sheets are integrally connected in the plane direction and metal fixtures 5 are fixed at the inside of respective folded parts 4, and the metal fixtures 5 arranged at every other corner are mutually tightened by bracings 2. Triangular shapes are formed by both adjacent sides of respective folded parts 4 and the bracings 2 to retain the angles of the folded parts 4. Further, other bracings 2 are added to increase the assembling strength of the whole body. Therefore, folding metal sheets are made costless and tightened by bracings 2 in a simple structure. In this way, the structure is costlessly assembled and the construction period of time is shortened, and the corners of the folded parts 4 are reinforced by the bracings to make the whole structural body hardly deformable and increase the strength.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an arch-shaped structure.

[0002]

2. Description of the Related Art In general, it is preferable that a large space can be obtained at a cost as low as possible, such as a warehouse, a pasture, a garage, a material storage area, etc., which are not directly related to human life. Conventionally, as such a structure, for example, the roof and the wall are constructed by bending a single plate, and this is supported by a simple structure support, or a single large plate is connected in an arch shape. There are known ones having an integral structure constituted by simply bending them.

[0003]

In either case, the structure itself is simple, but in the former case, the support often hinders the movement of humans, and the steel frame is assembled by bolting or welding. In addition, since the latter is continuously bent, the processing of the member is troublesome. Therefore, it is not very cheap.

[0004] It is an object of the present invention to solve the above problems and to provide a structure having a simple structure, a low cost, a large space, and a high strength.

[0005]

In order to solve the above-mentioned problems, a structure according to the present invention comprises a metal folded plate formed so that a peak and a valley are continuous with each other in a longitudinal direction of the ridge or the valley. The structure body is formed so as to be bent at right angles to form an arch-shaped structure body as a whole, and an appropriate portion of the inner surface of the structure body is tightened with a brace to hold the shape.

[0006] Instead of the brace, a shape holding means for holding the shape of the bent portion may be attached to the inner surface of the structure body.

[0007]

FIG. 1 shows a structure according to the present invention, in which an arch-shaped structure body 1 is tightened by a brace 2.

As shown in FIG. 4, the structure body 1 may be constituted by a normal metal folded plate 3 formed in a square wave shape (or a round wave shape) in which peaks and valleys having a square cross section are continuous. The folded plate 3 is bent at an obtuse angle at a plurality of locations, and is formed in an arch shape as a whole. The folded plate 3 is bent so as to be perpendicular to the length direction of the crest or valley.

The structure body 1 may be integrally formed by connecting several folded plates 3 in the plane direction.
The size of the frontage and depth of the structure body 1 can be increased or decreased depending on the number of the folded plates 3 connected.

Next, the structure body 1 has a small overall strength when folded, and cannot maintain its shape. Therefore, the structure body 1 is reinforced by the brace 2 as shown in FIGS. That is, the mounting brackets 5 are fixed inside each bent portion 4, and the mounting brackets 5 arranged alternately are tightened by the brace 2. In this case, FIG.
As described above, the turnbuckle 6 is attached to one mounting bracket 5, the brace 2 is attached to the turnbuckle 6 and the other mounting bracket 5, and the turnbuckle 6 is rotated to tighten to an appropriate strength. Thus, a triangle is formed by the sides a and b on both sides of each bent portion 4 and the brace 2, so that the angle of the bent portion 4 is maintained in that state.
Further, by adding another brace 2 in addition to the above-mentioned brace 2, the overall assembling strength becomes stronger.

Since the brace 2 is stretched inside the structure body 1, the inside space of the structure body 1 is limited to some extent. However, the brace 2 is the structure body 1
The space is limited along the inner peripheral surface, so that the degree of limitation of the space is much smaller than in the case where columns or the like are provided. In this case, the smaller the number of bent portions 4 located in one brace 2, in other words, the shorter the length of one brace 2, the more the opening limited by the brace 2. The space can be enlarged.

The arrangement of the brace 2 is not limited to the illustrated example. They may be arranged as shown in FIG.

According to the above configuration, since the folded plate 3 has the peaks or valleys formed in a rib shape, it is difficult to deform the folded plate 3 at right angles to the length direction of the peaks or valleys. Further, since the entire structure is formed in an arch shape, the structure is unlikely to be deformed even if only the front and rear ends or the center of the structure is lifted, that is, if the structure is bent in parallel with the crest or valley of the folded plate.

Further, the structure body 1 itself is easily deformed so that the angle of the bent portion 4 becomes larger or smaller, but the angle of the bent portion 4 is changed by the brace 2 as described above. The deformation is prevented because it is retained by the effect.

Further, since the angle of the bent portion 4 can be changed depending on the degree of tightening of the brace 2, the frontage of the structure body 1 can be adjusted to a certain extent by widening or narrowing.

In short, when the folded plate 3 is used, the whole structure is very hard to be deformed and has a high strength.

The shape holding means for securing the shape of the structure body 1 is not limited to the brace 2. For example,
As shown in FIG. 6, a plate-like body 7 fitted into the bent portion 4
May be fixed to the inner surface of the structure body 1. Alternatively, as shown in FIG. 7, an arch-shaped aggregate 8 corresponding to the shape of the structure body 1 may be arranged along the inner surface of the structure body 1 and fixed by appropriate means. For small structures this is sufficient.

[0018]

According to the first aspect of the present invention, the metal folded plate formed so that the peak and the valley are continuous is bent so as to be perpendicular to the length direction of the peak or the valley, and the entire arch is formed. The main body of the structural body is formed and appropriate portions of the inner surface of the main body 1 are tightened by braces. The metal folded plate is inexpensive, and the tightening by the braces can be performed by a simple structure. It can be assembled at low cost and the construction period is short.

Further, since a metal folded plate is used and the whole is arch-shaped, the strength of the structure itself is large, and the bent portion is reinforced by a brace so as not to be deformed. It is difficult to deform and has high strength.

The same effect can be obtained even when the shape holding means for holding the shape of the bent portion is attached to the inner surface of the structural body in place of the brace as in the second aspect of the invention. It is.
