Description

The present invention relates to a K-shaped brace frame used in the construction of structures.

As one of the structures of the structure using the steel frame, the foundation is installed on the foundation, and the beam material is hung over the upper part between the corner columns provided in the upright state at the corner of this foundation, and the foundations facing each other vertically. There is a frame structure constructed by arranging a brace frame between the beam material and the beam material and between the beam material and the beam material, and by providing an intermediate column in an upright state as needed, and on top of this frame structure. It is known that a roof structure is provided.

The brace frame used in the above-mentioned framework structure is composed of a pair of parallel vertical column members made of steel pipes and a steel pipe brace member that connects the vertical column members on both sides to each other. The brace material has a diagonally downward upper brace material fixed to the upper end portion of one vertical column material and a diagonally upward lower brace material fixed to the lower end portion of one vertical column material. The collective end of the upper brace and the lower brace is welded to the vertical middle of the other vertical column to form a K-shape when viewed from the front.

It is difficult to connect the vertical column material and the vertical column material.

In addition, wooden houses and wooden stores can be designed more flexibly depending on the length and combination of wood than structures using steel frames, and the floor plan and ceiling height are more flexible. For this reason, the distance between the vertical column members and the beam members on both sides of the above-mentioned brace frame becomes various sizes, and it is difficult to change the length of the above-mentioned H-shaped steel.

Therefore, the problem to be solved by this device is to provide a brace frame capable of connecting the beam material and the vertical column material according to the distance between the beam material and the vertical column material of the frame structure in the wooden structure. To provide.

The brace frame 10 according to the present invention is configured as described above. Next, a method of installing the brace frame 10 on a wooden structure having a frame structure will be described. First, the brace frame 10 is in a state in which the fixing members 20 of the pair of vertical column members 11 and 12 are rotated so that the fixing members 20 are brought close to the top plate 18 of the pair of vertical column members 11 and 12. Subsequently, as shown in FIG. 4, the brace frame 10 is built between the base 2 provided on the foundation 1 and the beam member 4 spanning the upper part of the corner column 3 so as to be in an upright state. After that, with the parallelism of the pair of vertical column members 11 and 12 adjusted, the fixing members 20 of the pair of vertical column members 11 and 12 are rotated to raise the fixing member 20 and the fixed surface to the beam member 4. Bring 20a into contact. In this contact state, the base plate 17 of the pair of vertical column members 11 and 12 and the base 2 are fastened with bolts and nuts. Further, as shown in FIG. 5, the fixing member 20 of the pair of vertical column members 11 and 12 and the beam member 4 are fastened by a fastener 30 made of bolts and nuts. As described above, the brace frame 10 is installed between the base 2 and the beam member 4 of the wooden structure having a frame structure.

The brace frame 10 is provided with a fixing member 20 at the upper ends of a pair of vertical column members 11 and 12. The downwardly extending male screw 21 provided on the fixing member 20 is screwed to the female screw 19 provided on the top plate 18 of the pair of vertical column members 11 and 12. Therefore, by rotating the fixing member 20, the distance between the fixing surface 20a of the fixing member 20 and the top plate 18 of the vertical column member 11 (vertical column member 12) can be adjusted. When the brace frame 10 is built so as to be in an upright state between the base 2 provided on the foundation 1 and the beam member 4 spanning the upper part of the corner column 3, the beam member 4 and the fixing member 20 are constructed. There may be a gap between the fixed surface 20a and the fixed surface 20a. Here, in particular, wooden houses and wooden stores can be flexibly designed according to the length and combination of timber, and the floor plan and ceiling height are highly flexible. Therefore, the fixed surfaces of the beam member 4 and the fixing member 20 are fixed. There is a gap between it and 20a.

In the brace frame 10 of this embodiment, even if there is a gap between the beam member 4 and the fixing surface 20a of the fixing member 20, the fixing member 20 of the pair of vertical column members 11 and 12 is rotated. , The distance between the beam member 4 and the fixing surface 20a of the fixing member 20 can be adjusted.

Further, the fixing member 20 of the brace frame 10 has a plate shape. If the fixing member 20 has a plate shape, the distance between the fixing surface 20a of the fixing member 20 and the top plate 18 of the pair of vertical column members 11 and 12 can be further reduced. As a result, even when the distance between the beam member 4 and the top plate 18 of the pair of vertical column members 11 and 12 in the wooden structure of the framework structure shown in FIG. 4 is small, the fixing member 20 is attached to the beam member. It can be fixed to 4.

In the above embodiment, as shown in FIG. 2, the fixing member 20 having a rectangular plate shape having the same width dimension as the width dimension in the front-rear direction of the vertical column member 11 has been described as an example. As shown in FIG. 6, the fixing member 20 has a substrate portion 22 having the same square shape as the cross-sectional shape of the vertical column member 11, and a pair of protrusions extending from the substrate portion 22 at right angles to the cylinder axis of the vertical column member 11. It may have plate portions 23, 23.

In the fixing member 20 shown in FIG. 6, a pair of projecting plate portions 23, 23 are arranged at right angles to each other with respect to the substrate portion 22. As shown in FIG. 7, each of the pair of projecting plate portions 23, 23 is formed with a through hole 20b, and has the same width dimension as the length of one side of the substrate portion 22. The brace frame 10 having the fixing member 20 shown in FIG. 6 is formed by, for example, a wooden structure having a frame structure, in which the vertical column member 11 is located at a corner portion of the base 2, and the base 2 and the beam member 4 are attached to each other. It can be installed between them (see FIG. 8). In this case, as shown in FIG. 7, in the fixing member 20 of the brace frame 10, the pair of protruding plate portions 23, 23 are arranged at right angles to each other, and the beam members 4, 4 (two-dot chain line in FIG. 7). It will be in a state of being arranged along the reference). Therefore, the substrate portion 22 of the fixing member 20 and the pair of protruding plate portions 23, 23 can be prevented from protruding from the beam member 4.
