2. Description of the Related Art In Japan, wooden structures are
It is made by (i) traditional frame construction method developed from ancient traditional construction methods, (ii) frame wall construction method, (iii) panel type prefabricated construction method, and (iv) combination of these. The conventional frame construction method (i) is mainly used. The conventional frame construction method is the foundation, pillars,
This refers to a structure made up of beams, girders, girders, braces, etc., and joints that are tightly connected with joints, joints, and metal fittings. The joint means a joint for connecting two members in the material axial direction, and a dovetail joint, a hook joint, or a simple butting system in which a metal object is hit with a bolt and used. The term "joint" refers to the joining of two members in the direction at right angles and in the direction of inclination, and mortise-punching, dovetailing, large inserts, indentations, and similar simple sizing systems using metal objects are used. When constructing, adopt a unit frame such as columns and beams, or a bearing wall such as braces, so that it can safely and effectively resist external forces acting on the building, and its placement and external forces It is necessary to consider the direction, etc. comprehensively and make an appropriate structure. With respect to horizontal loads on buildings due to seismic force, wind pressure, etc., it is considered effective to prevent the deformation of the frame by placing diagonal braces on the diagonal of the frame. The braces are used not only for the walls but also for the horizontal structures and the connecting surfaces of the huts. In addition to this, staggering, firing, etc. are also effective for increasing the rigidity of the frame.

Braces include those that resist tensile forces and those that resist compressive forces. In Figure 18, thickness 1.5c
m shows a brace (200) having a width of about 9 cm and a tensile force. As shown in FIG. 18, a cutout (201a) is provided on the outer surface of the horizontal member (201), and a brace (200) is fitted into the cutout (201a) and fixed with a nail. And bracing (20
When a tensile force acts on (0), the column (202)
1) To prevent it from slipping out of the strip-shaped hardware (20
It is tied up in 3). In FIG. 19, the same size as the pillar,
A brace (204) carrying a compressive force is shown. This is because the braces (204) are in contact with the horizontal members (205) and the pipe columns (206), the bolts (208) are inserted into the braces (204) and the pipe columns (206), and the nuts ( 209). Then, when a compressive force acts on the braces (204), the braces (204) are crossed (205).
A strip-shaped metal fitting (210) is provided in the vertical direction so as not to spring out. FIG. 20 shows another example of the brace that bears the compressive force. This is because the braces (212) of the same size as the through columns (211) are in contact with the horizontal members (213) and the through columns (211), and when a compressive force acts on the braces (212). ) Does not bounce the horizontal member (213), the strip-shaped metal fitting (2
14) is provided. The brace that bears the compressive force is not only the same size as the column as shown in FIG. 19 and FIG. 20, but also the column is divided into three or two, that is, the thickness is 3 cm or 4.5 cm and the width is about 9 cm. used. In FIG. 21, the column halves (215) are connected to the horizontal member (217) and the columns (21) by the metal fittings (216).
The one fixed in 8) is shown. This joining hardware (216)
Has a rectangular contact portion (216a) for contacting and fixing the horizontal member (217) and a rectangular contact portion (216b) for contacting and fixing the pillar (218). , The plate (216c) is provided upright from two adjacent side edges, and the plate (216c) has a square shape so that the braces (215) can be fixed to the plate (216c). It has become. FIG. 22 shows a plate-like joining metal fitting (2
Another example of 20) will be shown. As shown in FIG. 22, a plate-shaped joining metal fitting (220) is struck by a nail or the like on the outer surface of the horizontal cross member (221) and the pipe column (222), and the horizontal cross member (2
21) and the pipe column (222) are fixed, and a bolt (223) is inserted into a brace fixing hole formed in the plate-shaped joining hardware (220) to attach the end of the brace (219). It is fixed so that it can bear the compressive force. The rigidity of the framework can be further increased by using the braces instead of the one-sided hanging as shown in FIGS. 18 to 22. In the unit frame, the joining points are reinforced by strip-shaped joining hardware, T-shaped joining hardware, L-shaped joining hardware, etc. to resist external force, especially horizontal load.

The above-mentioned unit frames and bearing walls due to braces have been considered exclusively for horizontal loads.
It meets the earthquake and wind resistance calculations and allowable stress levels of the Building Standards Law Construction Ordinance revised in 1981, but sufficiently copes with the three-dimensional complex shaking, load, and twist that occur in wooden structures due to a direct earthquake. It's hard to say that you can do it. That is, the strip-shaped metal fittings, the T-shaped metal fittings, the L-shaped metal fittings, and the like have only an effect on the stress in two directions at most, and the three-dimensional shaking, load, and
It is not possible to sufficiently deal with the stress generated by twisting or the like. Further, in the structures of FIGS. 19 to 22 that resist the compressive force, the forces acting on the braces due to the three-dimensional shaking, load, and twist due to the direct earthquake cause the braces to buckle or the braces to join. It bounces off and cannot show sufficient resistance, leading to collapse or twisting of the building. It is considered that the braces having a structure that resists tensile force as shown in FIG. 18 are more effective for the direct earthquake, but in the braces as shown in FIG. 18, the cross members (201) and the braces are used. Since the structure is such that only the paddle (200) is fixed with the nail, the binding force is weak, the nail comes off, and the effect is lost. Columns, foundations, braces to resist compressive forces
As shown in Figs. 21 and 22, the metal fittings for fixing to the horizontal members have already been developed and used, but the braces that resist tensile forces are firmly attached to the pillars, bases, horizontal members, etc. No metal fittings have been developed for connecting to. Fire reinforcement is used to reinforce the cross members such as beams and girders in the diagonal direction, but this only resists the compressive force and occurs between the cross members due to the direct earthquake. No horizontal braces have been developed to effectively resist the tensile force against twisting, and no metal fittings have been developed to firmly connect the horizontal braces to the cross members. From these things, due to the direct earthquake,
Traditional wooden structures have collapsed and twisted, resulting in frequent death and loss of property.

The framed wall construction method is also called two-by-four, and usually a plurality of timber having a nominal cross-sectional dimension of 2 × 4 inches is used to form a frame, and plywood or various face materials are nailed to form a wall. It is a thing. The frame wall in Two-by-four is a bearing wall that ensures wind resistance and earthquake resistance. Therefore, if the size of windows is increased or the number of windows is increased, it becomes difficult to secure the proof stress, and the wind resistance and seismic resistance are deteriorated. That is, in a two-by-four building with large windows or a large number of windows arranged, three-dimensional sway, load,
Twisting etc. occurs, leading to collapse or twisting. Because of this, there are restrictions on the layout and size of windows.
Larger windows are preferred as lifestyles diversify,
It is preferred to increase the number of windows, but due to the above-mentioned restrictions, conventional two-by-four cannot fully meet such requirements, and the windows can be made large, and many windows are arranged. Two-by-four with excellent wind and earthquake resistance is being sought after.

[0006]

The present invention was created as a result of earnest research in view of the above-mentioned actual circumstances,
Effectively copes with the stress generated by three-dimensional shaking, load, twist, etc. due to a direct earthquake, etc., and at least prevents the collapse of buildings with frame structures, and as a result eliminates the risk of life due to the collapse of the buildings. Therefore, in order to reduce the risk of twisting of the building and to use the building safely for a long period of time without damaging the property value, the braces that resist the tensile force should be framed. It is an object of the present invention to provide a metal fitting for bonding that can be effectively fixed to the above. Further, in particular, in a building having a frame structure, it effectively copes with the stress generated by three-dimensional shaking, load, twist, etc. due to an earthquake directly underneath, and at least prevents the collapse of the wooden building. In order to eliminate the danger of life due to the collapse of things, reduce the risk of twisting etc. in the wooden structure and make it possible to use the wooden structure safely for a long time without damaging the property value, An object of the present invention is to provide a metal fitting for joining, which can effectively fix braces that resist force to pillars, bases, horizontal members, and the like.
