Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of braces that can be assembled in an area surrounded by left and right columns (tube columns and through columns) and upper and lower horizontal members (beams and bases) that form the framework of the outer wall of a wooden building.

[0002]

[Prior art]

 In a wooden building, pillars, beams, girders, etc. are made of wood, and the floor is constructed by placing a large pull on the outline, base, and bundle, placing joists, and arranging floorboards. , Etc., the roof is made up of, etc., and the roof forms a truss with an amber, a bunch, a lining, and a gassho. The structure has been applied. In addition, diagonal members (reinforcing materials) such as braces, holding columns, and bearings are used together to make them durable against wind pressure and seismic force. Conventionally, the braces as the reinforcing members are long members 1 crossed in an X-shape between columns 5 sandwiched by upper and lower horizontal members 6, 6 as illustrated in FIG. , 1 are fixedly arranged to form two triangles and the rigidity is increased in all vertical and horizontal diagonal directions, ensuring durability.

[0003]

[Problems to be solved by the device]

 In the conventional braces, only the ends of the long members are fixed, so that the long members 1 and 1 resist the compressive force P at their entire length L as shown in FIG. A thick buckling material is necessary to ensure high rigidity because the central part is easily bent due to the long buckling distance.

[0004]

[Means for Solving the Problems]

 The purpose of the present invention is to increase the rigidity of the braces, and the structure is such that two columns are fixed by crossing in an X shape between columns that are sandwiched by upper and lower horizontal members. Of the long members, the connecting members fixed to the facing surfaces of the pillars, and the crossing portions of the connecting members and the long members are integrally bonded along at least one of the inner and outer surfaces of the outer wall. It is in the braces of a wooden building consisting of possible reinforcement plates. The braces can be formed into a bracing unit in which two long members and a reinforcing plate are integrally fixed in advance.

[0005]

[Action]

 In the braces of the present invention, the long member is integrally connected to the columns arranged on the left and right at the intersection by the reinforcing plate through the connecting member, so that the compressive force applied to the long member is exerted. Since each of them acts on the upper part and the lower part, the buckling distance is less than half and the rigidity is dramatically improved. Further, if the two long members and the reinforcing plate are previously formed in a bracing unit integrally fixed to each other, the assembling on site becomes easy.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. 1 (a) and 1 (b) show constituent members of a brace, where 1,1 are long members, 2,2 are connecting members, 3 is a reinforcing plate, and long members 1,1 A thick plate is used for the ends, and the ends of the long members 1, 1 are crossed in an X shape, and the corners are cut so as to match the corners that join the horizontal members and the columns. The strips 1 and 1 are dropped, and the reinforcing plates 3 are integrally fixed by nailing to the one side where the strips 1 and 1 cross each other in an X shape, and the contact plates 4 and 4 are sandwiched at the intersections to eliminate the step. It is formed in the brace unit M. Plywood such as veneer is preferably used for the reinforcing plate 3, and the reinforcing plate 3 is formed to have a length corresponding to the inner method between columns and a width corresponding to about 20% of the interval between the upper and lower beams. Further, as the connecting member 2, the vertical length is matched with the width of the reinforcing plate 3 and the thickness may be arbitrary, but the width is smaller than the width of the striking surface of the column by the thickness of the reinforcing plate 3. Things are used.

In the braces composed of the above-mentioned members, first, the connecting members 2 and 2 are respectively displaced from the surface of the pillar 5 inward by the thickness of the reinforcing plate 3 on the facing surfaces of the pillars 5 and 5, and the nails are nailed. Then, the bracing unit M including the two long members 1 and 1 crossed in the X-shape and the reinforcing plate 3 fixed to the long members 1 and 1 is attached to the left and right studs. It is placed in the area surrounded by 5, 5 and upper and lower horizontal members 6, 6 and each end of the long members 1, 1 is firmly fixed by using the connecting hardware 7, 7, ... . Finally, both ends of the reinforcing plate 3 are nailed to the connecting member 2, and the reinforcing plate 2 is integrated so as to be continuous with the surface of the pillar 5 without any step, and the assembly is completed (see FIG. 2).

As described above, for example, the bracing unit M is attached to a key portion in a wooden structure, for example, between the columns 5 and 5 in a corner portion, as shown in FIG. Since the paddle unit M and the studs 5 and 5 are integrated with each other, as shown in FIG. 5 (b), the reinforcing plate 3 fixed to the pillar via the connecting member 2 is provided at the intersection of the long members. The flexure is suppressed, and the compressive force P acts individually on the upper part and the lower part at the intersection, so that the buckling distance is reduced to L / 2 and the rigidity is reduced to about 4 Doubled.

In the above-described embodiment, since only the bracing unit in which the long member and the reinforcing plate are integrated is attached in advance, workability is good and standardization is easy, but each member can be assembled on site. However, the order in which the members are nailed and fixed at that time is not limited to the embodiment, and they may be fixed by means other than nailing. Further, as shown in FIG. 4, for example, a square bar that can secure a predetermined thickness even when the step parts 2a and 2a are formed by fitting them to the crossing parts is adopted for the long members 1'and 1 '. Although the backing plate is omitted, the intersection is reinforced with a metal object, although not shown, a fitting portion for fitting the end of the long material to the horizontal member or column is formed, or other means is used. And then fix it

It is sufficient that the reinforcing plate is provided on at least one of the inner and outer surface sides of the outer wall, but it can be provided on both surfaces, and the width of the reinforcing plate can be increased or decreased, or a reinforcing auxiliary plate can be used together. It is also possible to make appropriate changes within the scope of the present invention, such as adding auxiliary columns.

[Effect of device]

 According to the present invention, since the connection between the braces and the columns is enhanced, not only the compressive force but also the rigidity against deformation such as twisting is strengthened, which is a great measure for strengthening wooden buildings such as earthquakes. Be expected.
