Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is assembled in an area surrounded by left and right columns (pipe columns and through columns) and upper and lower horizontal members (beams and bases) that form a framework of an outer wall of a wooden building. The present invention relates to a braced braces and an assembly method for the braces.

[0002]

2. Description of the Related Art In a wooden building, pillars, beams, girders, etc. are made of wood, and a large pull is placed on the outline, base, and bundle, a joist is laid, a floorboard is stretched to form the floor, and the outer wall The base is composed of pillars, furring strips, etc., and the roof is made up of a trough, a bundle, a lining, and a truss, and a mist is placed on the roof.
It has a structure in which rafters are placed, field boards are laid, and roofing is applied. In addition, diagonal members (reinforcing materials) such as braces, columns, and struts are used together to make them durable against wind pressure and seismic force. The braces as the reinforcing material are
Conventionally, as illustrated in FIG. 6, a long member 1, which is crossed in an X-shape, between a column 5 and a column 5 sandwiched by upper and lower horizontal members 6, 6.
1 is fixedly arranged to form two triangles, and durability is ensured by adopting a configuration that enhances rigidity in all vertical and horizontal diagonal directions.

[0003]

In the conventional braces, only the ends of the long member are fixed, so that the long members 1 and 1 have the entire length L as shown in FIG. Since it resists the compression force P and the central portion is easily bent due to a long buckling distance, a thick material is required to secure high rigidity.

[0004]

DISCLOSURE OF THE INVENTION The present invention is intended to increase the rigidity of braces, and its structure is such that an X-shaped space is provided between columns that are sandwiched between upper and lower horizontal members. At least one of the inner wall and the outer wall of the outer wall, the two long members that are fixed by intersecting with each other, the connecting members that are respectively fixed to the facing surfaces of the pillars, and the intersections of the connecting members and the long members. The braces of a wooden building consisting of a reinforcing plate that can be integrally joined along the surface of
Two long members are fixed in an X shape in the area surrounded by the left and right columns and the upper and lower horizontal members that form the framework of the outer wall of the wooden building, and are connected to the opposite sides of the columns, respectively. There is another method of assembling a bracing, in which the reinforcing plates are integrally bonded to at least one of the inner surface and the outer surface of the outer wall to the connecting member and the intersecting portion of the elongated member. Further, in the above-mentioned braces, the two long members and the reinforcing plate can be formed in advance in a bracing unit integrally fixed to each other.

[0005]

The braces of the present invention are joined to the long members by integrally connecting the long members to the columns arranged on the left and right at the intersections by the reinforcing plate via the connecting members. Since the compressive force acts on the upper part and the lower part individually, the buckling distance becomes half or less, and the rigidity is dramatically improved. Further, the method of assembling the braces according to the present invention has a slightly increased number of nailing steps as compared with the conventional method, and there is almost no change in workability. The bracing unit facilitates on-site assembly.

[0006]

An embodiment of the present invention will be described with reference to the drawings. 1 (a) and 1 (b) show the structural members of the brace, 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 cut off so that they match the corners that are the joints of the horizontal members and the pillars while intersecting each other in the X shape. The elongated members 1 and 1 are crossed in an X shape with each other, and the reinforcing plates 3 are integrally fixed by nailing to one surface of which the step plates are eliminated by sandwiching the contact plates 4 and 4 at the intersecting portions. It is formed in the bracing unit M. The reinforcing plate 3
Is preferably made of plywood such as veneer, and is formed to have a length that conforms to the internal dimension between columns and a width that corresponds 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.

The braces formed by the above-mentioned members are as follows.
The connecting members 2 and 2 are respectively moved to the opposite surfaces of the columns 5 and 5 from the surface of the column 5 inward by the thickness of the reinforcing plate 3 and fixed by nailing, and then crossed in the X shape. Book long material 1,1
And the bracing unit M consisting of the reinforcing plates 3 fixed to the long members 1, 1 are arranged in the area surrounded by the left and right studs 5, 5 and the upper and lower horizontal members 6, 6. The end portions of the scale members 1 and 1 are 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 column 5 without any step (see FIG. 2).

As described above, for example, the bracing unit M is assembled to a key point in a wooden building, for example, between the columns 5 and 5 in a corner portion, as shown in FIG. Since the studs 5 and 5 are integrated, as shown in FIG. 5B, the reinforcing plate 3 fixed to the pillar via the connecting member 2 suppresses the bending of the long member at the intersection. At the same time, since the compressive force P acts on the upper part and the lower part at the intersection, the buckling distance is halved to L / 2, and the rigidity is increased to about four times.

In the above-mentioned embodiment, since only the bracing unit in which the long member and the reinforcing plate are integrated is attached in advance, the workability is good and the standardization is easy, but even if each member is assembled on site. Of course, in that case, the order of nailing and fixing the respective members is not limited to the embodiment, and they may be fixed by means other than nailing. Also, each long material 1 ', 1'
Further, as illustrated in FIG. 4, for example, a square bar that can secure a predetermined thickness even if the fitting step portions 2a, 2a are formed at the intersection is used to omit the caul plate, or the intersection is made of metal. Although not shown in the drawings, it may be reinforced or formed with a fitting portion for fitting the end portion of the long material to the horizontal member or column, or may be fixed by using other means.

It is sufficient that the reinforcing plate is provided on at least one of the inner and outer surfaces 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 possible to make appropriate changes without departing from the spirit of the present invention, such as adding or adding auxiliary columns.

[0011]

According to the present invention, not only the compressive force but also the rigidity against deformation such as twisting is enhanced by increasing the connectivity between the braces and the columns, and it is possible to start an earthquake in a wooden building. Highly expected as a strengthening measure.
