Abstract

PURPOSE:To change the position of a brace so as to cope with change in function of a building and to effectively utilize the building. CONSTITUTION:A first brace member A and a second brace member B rotatably pivoted by a column P and a girder Q through pins and 1', respectively, are engaged with each other capably of sliding, and a groove hole 2 in the longitudinal direction is provided on the brace material A out of both brace materials. A pin for sliding 4 which slides in the groove hole 2 is arranged on the other brace member B, and high strength bolt holes 3 and 3' are drilled in both brace members A and B, respectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brace structure in a steel frame building.

[0002]

2. Description of the Related Art In a conventional steel frame brace structure, the number of required braces and the positions thereof are determined in advance and the braces are arranged. The placement of the braces is basically immobile during the life of the building.

[0003]

However, in some cases, a change in the function of a building may cause the brace to be a functional obstacle. In such a case, it is not allowed to remove the brace as described above, and it is difficult to deal with the function change. The present invention has been proposed in view of the above problems of the prior art, and the purpose thereof is to change the position of the brace so that the function of the building can be changed and the building is effectively The point is to provide a folding brace structure to be utilized.

[0004]

In order to achieve the above object, a folding brace structure according to the present invention comprises a first brace member pivotally supported on a pillar side and a girder side pivotal member. The second brace member is freely pivoted, and the brace members are slidably fitted to each other and one of the brace members is provided with a slot extending in the longitudinal direction, and the other brace member is formed in the other brace member. Sliding pins that move in the groove holes are provided, and bolts are inserted into the high-strength bolt holes respectively formed in the brace members so that they can be loosened.

[0005]

Since the present invention is constructed as described above,
When designing a brace structure, once the required number of braces is determined, the actual number of braces should be a few extra than the number of braces, so that the brace has the freedom to accommodate the extra installation. Becomes

The brace guides a groove hole extending in the longitudinal direction of one of the brace members and a sliding pin disposed in the other brace member, centering on the column-side pivotal support and the girder-side pivotal support, respectively. Since it will be folded as, as always, only the required number of braces will function, other extra braces will be folded and the function of the building will change,
If a failure occurs in the current brace, the function change can be dealt with by replacing it with a folded brace.

[0007]

The present invention will be described below with reference to the illustrated embodiments. A is a rectangular tube-shaped first brace whose lower end is pivotally supported by a pillar P via a pin 1 and B is a rectangular tube which is pivotally supported by a girder Q via a pin 1 '. Second brace of the shape.

A groove 2 extending in the longitudinal direction is formed on the side surface of the first brace A, and high-strength bolt holes 3 are formed at the tip and the middle. The second brace B is slidably fitted in the first brace A, and the sliding pin 4 slidably pierced in the slot 2 is transversely penetrated in the direction perpendicular to the longitudinal direction of the brace. At the same time, a high-strength bolt hole 3'is formed at a position corresponding to the high-strength bolt hole 3 in the first brace B.

The first and second braces A and B are slidably fitted so that the sliding pin 4 slides along the slot 2. When the brace is to function, the high strength bolt holes 3 of both the braces A and B are set in the state of M in FIG.
Tighten 3'with the high-strength bolt 5. Both braces A and B
When folding, remove the high-strength bolt 5 and remove the arrow X.
By pushing in the direction, each of the braces A and B is rotated about the pins 1 and 1'as shown in A'and B'as shown in FIG. 1 and folded as shown in A "and B". At this time, there is no fear that the braces A and B will be separated by the groove 2 and the sliding pin 4.

FIG. 3 shows an application example of the present invention, where one brace is provided at three places where the required number of braces is two and three extra braces are provided. (See FIG. 3 (a)) FIG. 3 (b), FIG. 3 (c) and FIG. 3 (d) show the brace A,
The variation of the function by folding B is shown, and the portion Y is a functionally free portion.

[0011]

As described above, the folding brace structure according to the present invention is one of a pair of brace members pivotally supported on the pillar side and the girder side and slidably fitted to each other. If the brace material is provided with a slot extending in the longitudinal direction and the other brace material is provided with a sliding pin slidably fitted in the slot, the brace can be folded and unfolded. As a result, the brace is installed in excess of the required brace installation location in the building, and since there is freedom by the amount of this extra installation, it will be folded if the function of the building changes and the current brace fails. It can be replaced with a brace to respond to functional changes.

Therefore, the layout of the functions of the factory can be freely set without worrying about the position of the brace, and the folding and unfolding work of the brace can be easily performed even by an amateur without requiring a professional.
