In the space, bracings 5 and 6 are provided to support the base 1 and the contact portion between the beam 2 and the pillars 3 and 4, so that a large force that tends to sway in the lateral direction due to an earthquake or the like is exerted on the wooden building. When it hits the ground, it can suppress large rolling and improve earthquake resistance.

However, the ends of the braces 5, 6 provided in the rectangular space formed by the base 1, the beam 2 and the two pillars 3, 4 are the ends of the base 1, the beam 2 and the pillars 3, 4. It is fixed to the contact part with nails 8 etc. via brace fixing metal fittings 7, but if the shaking becomes extremely large, a force is applied especially to the connection part of the brace fixing metal fittings 7 to the base 1 and the beam 2 in the direction of disengagement. There is a gap between the ends of the braces 5, 6 and the bracing fixture 7 and the base 1 and the beam 2, and the tenons formed at the ends of the columns 3 and 4 are the base 1 and the beam 2. There is a problem that the building inclines when trying to escape from the mortise formed in the building, and in order to solve this problem, the lower ends of columns 3 and 4 and the base 1 and the upper ends of columns 3 and 4 and beams 2 are drawn. Apply the chevron plate 9 as shown and attach it with nails 10 etc. It is.

However, there are restrictions on the locations where the chevron-shaped plate 9 can be used. For example, as shown by the two-dot chain line in FIG. When the beams and beams 12 are present at a right angle, there is a problem that the chevron plates 9 cannot be fixed to the columns 3 and 4 and the base 1 and the beams 2 by the nails 10 or the like.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. First, the first embodiment shown in FIGS. 1 to 6 will be described. A base 21 provided on a concrete foundation (not shown) is provided with a large number of columns 22, 23, ... Standing vertically. ing. In the drawing, two pillars 22 and 23 that are adjacent to each other and are parallel to each other are shown, and a rectangle formed by the base 21, a beam 24 above the base 21 and parallel to the base 21, and the two pillars 22 and 23. In the space, the braces 25 and 26 are provided in an X shape along two diagonal lines. The lower end of one brace 25 is in contact with the base 21 and one of the columns 22, and is fixed by a nail 28 or a screw via the brace fixing metal fitting 27 shown in the above-mentioned conventional example. The upper end of 25 is in contact with the beam 24 and the other pillar 23, and is fixed by nails 28 or screws through bracing fixing metal fittings 27. The lower end of the other brace 26 is in contact with the base 21 and the other column 23 and is fixed by nails 28 or screws through the brace fixing metal fitting 27, and the upper end of the other brace 26 is connected to the beam 24. It abuts one of the pillars 22 and is fixed by nails 28 or screws via bracing fixtures 27. The longitudinal middle portions of these two braces 25 and 26 overlap each other in the front-back direction, and within the overlapping area of the diamond, both braces 25 and 26 are driven from the other braces 26 located on the front side. It is fixed by nails 29. A face member 30 made of a vertically long rectangular plywood or the like is provided on the rear side of the middle portion of the two braces 25 and 26 in the longitudinal direction. The face member 30 is in contact with the rear surface of one of the braces 25 and is fixed by a large number of nails 29. The face member 30 is in contact with the rear surface of the spacer 31 made of wood attached to the rear surface of the other brace 26 by the nails 29, and is fixed by the plurality of nails 29.

By the way, in the present embodiment, the two braces 25, 26 have a side surface shape that is vertically oriented with respect to the base 21 at a position above the fixing portion by the bracing fixture 27 at the lower end. Is supported via an L-shaped binding metal fitting 32, and at the upper end, a side shape in which the space between the beam 24 and the beam 24 is oriented vertically at a position lower than the fixing portion by the brace fixing metal fitting 27 is L-shaped. It is supported via metal fittings 32. The abutting portion between the binding metal fitting 32 and the braces 25 and 26 and the abutting portion between the binding metal fitting 32 and the base 21 and the beam 24 are fixed by nails 33 or screws. In this case, the binding metal fittings 32 are positioned adjacent to the upper surface of the base 21 and the lower surface of the beam 24 so as to be adjacent to the brace fixing metal fittings 27, and are different from the base and the beam as in the conventional case. While it was impossible to use the chevron plate when the beams were present at right angles, in this embodiment, the base 21, the beams 24, and the binding members 32 located within the thickness of the columns 22 and 23 are used. As a result, the strength of the connecting portions of the braces 25, 26 and the columns 22, 23 to the base 21, the beams 24 can be improved.

In the wooden building of the above-mentioned embodiment, the mutually adjacent pillars 22 and 23 located between the base 21 and the beam 24 above the base 21 are arranged in an X shape along two diagonal lines. It is supported by the braces 25 and 26 provided, and can suppress rolling to a certain extent due to an earthquake. In addition to this structure, in the present embodiment, the longitudinal middle portions of the two braces 25, 26 are overlapped with each other in the front-rear direction, and a plurality of the braces 25, 26 are provided within the rhombus overlapping range. Fixing with two nails 29, and providing a face member 30 on the rear side of the middle portion of the two braces 25, 26 in the longitudinal direction, the face member 30 of one of the braces 25 located on the rear side. It is brought into contact with the rear surface and fixed with a large number of nails 29, and the face material 30 is brought into contact with the rear surface of the spacer 31 made of wood that is attached to the rear surface of the other brace 26 with the nail 29 to make a large number of nails. Since the braces 25 and 26 are fixed by the nails 29, the middle portions of the braces 25 and 26 in the longitudinal direction are not constrained by the face material 30 or the nails 29 and the edges thereof are cut off. The buckling distance of 26 can be less than 1/2. Therefore, the buckling load, that is, the limit load that the braces 25 and 26 can withstand in the longitudinal compression is four times or more, and as a result, a large force that tends to shake the wooden structure laterally due to an earthquake or the like. Even when it is exposed to a large amount of vibration, it suppresses a large amount of rolling, and the wooden structure can be greatly improved without damaging it. Further, as described above, the two braces 25 and 26 are located at the lower end at a position higher than the fixing portion by the bracing fixture 27 so that the space between the base 21 and the base 21 is supported by the binding fixture 32. In this case, since the space between the beam 24 and the beam 24 is supported by the binding metal fitting 32 at a position lower than the fixing portion by the bracing metal fixture 27, the strength of the connection portion of the columns 22 and 23 to the base 21 and the beam 24 is strong. Grows larger.

By the way, in the embodiment described above, the overlapping portion is fixed at the middle portion of the two braces 25 and 26 in the longitudinal direction, the spacer 31 is fixed to the other bracing 26, and the one bracing 25 is fixed. The face member 30 is fixed to the rear surface and the rear surface of the spacer 31 by the nail 29, but may be fixed by wood screws or staples.

Further, in the above-described embodiment, the adjacent columns 22 and 23 which are parallel to each other and are located between the base 21 and the beams 24 above the base 21 are provided in an X shape along two diagonal lines. An example is shown in which the middle portions in the lengthwise direction are supported by two braces 25, 26 that are connected and fixed to each other, but the beams located above and below the second floor and above are parallel to each other. Adjacent columns can be similarly supported.

Further, in the embodiment described above, in the rectangular space formed by the base 21, the beam 24 above it, and the columns 22 and 23 that are adjacent to each other and are parallel to each other, X is measured along two diagonal lines. Although the two braces 25 and 26 are provided in the shape of a letter, the braces may be provided along one of the two diagonal lines.

Although the side surface shape of the binding metal fitting 32 used in the first embodiment is L-shaped, the side surface shape obtained by welding two plate materials as in the second embodiment shown in FIG. 7 is T-shaped. Alternatively, a T-shaped binding member 32 may be used, or a T-shaped binding member 32 formed by bending one plate material as in the third embodiment shown in FIG. 8 may be used.

Further, as in the fourth embodiment shown in FIG. 9 and FIG. 10, it is possible to tightly connect the braces 25 and 26 to the base 21 and the beam 24 by the fastening metal fitting 32 having the L-shaped side and front shapes. Is.
