DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal joint used for connecting structures in the construction of a wooden framed house or the like.

[0002]

2. Description of the Related Art In recent years, joints of structures such as framed wooden houses are often reinforced with metal joints for the purpose of improving seismic performance.

In order to reinforce a base and a column, for example, such a joint is formed by using an L-shaped or convex joint formed of a metal plate, and the joint is fastened to both the base and the column with a bolt or a nail. doing. In this case, the fastening portion between the base and the pillar of the joint hardware has a 90-degree positional relationship about the base of the joint hardware.

As described above, when the joints of the structures are reinforced with metal joints, even if the structures are distorted due to an earthquake or the like, the base and the columns are firmly fixed, so that they can be easily separated. There is an effect that there is no.

[0005]

However, when the base and the column are fastened with a rigid metal joint, a force is directly applied to the fastening portions of the bolts and nails. Bolts and nails are damaged, slipped out, foundations and pillars are damaged, and the structure is going to collapse.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a metal joint capable of maintaining a reinforcing effect of a joint of a structure even when the structure is distorted due to an extremely large earthquake or the like.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a first aspect of the present invention is to provide a metal joint made of a metal plate for joining and reinforcing two or more structures, the structure being fixed to the structure. In this configuration, a corrugated buffer is provided between the joints to be formed.

According to a second aspect of the present invention, in the first aspect of the present invention, a joint portion to be fixed to the structure is protruded in three directions through an insertion hole of a fastening means such as a bolt, and is formed at a corner between adjacent joint portions. This adopts a configuration in which a wavy buffer portion is provided.

According to a third aspect of the present invention, in the first aspect of the present invention, two joints to be fixed to the structure by the insertion holes of the fastening means such as bolts are arranged substantially in an L shape, and the two joints are connected. This adopts a configuration in which a fan-shaped portion is provided with a wavy buffer portion.

According to a fourth aspect of the present invention, in the first aspect of the present invention, a joining portion for fixing to a structure with an insertion hole of a fastening means such as a bolt is coupled to both ends of the metal body having a length, The configuration adopts a configuration in which a corrugated buffer is provided at a position of the joint near the metal body.

At the position of each corner between 3 and 3, a buffer portion 8 in which the gathering portion 2 is bent in a wave shape
Is provided.

Since the buffer portion 8 is formed by bending a metal plate forming the collecting portion 2 in a wave shape, the buffer portion 8 can be expanded and contracted in the surface direction of the metal joint 1a. Between 3 and 3, the angle is variable.

The metal joint 1a of the first embodiment is
In the structure of the framed wooden house shown in FIG.
For example, it is used to reinforce the joint between the base 21 and the pillar 22 or the joint between the pillar 22 and the beam 23.

A second embodiment shown in FIG. 2 is an L-shaped joint 1 for reinforcing a joint in two directions of a structure from the inside.
b, using a metal plate of the required thickness,
And 3 are arranged in a substantially L-shape, and both joints 3 and 3 are connected at one side edge by a fan-shaped portion 9, and the fan-shaped portion 9 is provided with a wave-shaped buffering portion 8. 3 are provided with insertion holes 5 for bolts 4 and insertion holes for nails, respectively.

In the second embodiment, the fan-shaped portion 9 is provided with the corrugated buffering portion 8, so that the fan-shaped portion 9 can expand and contract in the plane direction with the base as the center. The angle becomes variable.

The third embodiment shown in FIG. 3 is an L-shaped metal joint 1c that reinforces the joints in two directions of the structure from inside similarly to the second embodiment described above. Using a metal plate having a thickness, the two joints 3 are formed at right angles L
The two joints 3 and 3 are connected by fan-shaped parts 9 and 9 at both side edges, and the fan-shaped parts 9 and 9 are provided with corrugated buffering parts 8 and 8. 3 and 3, an insertion hole 5 for the bolt 4 and an insertion hole for the nail are provided.

The metal joint 1 of the second and third embodiments
b and 1c are, for example, a joint between the base 21 and the column 22 or the column 2 in the structure of the wooden framed house shown in FIG.
It is used in a corner portion as a reinforcement for a joint between the beam 2 and the beam 23.

The fourth embodiment shown in FIG. 5 is a long plate-shaped metal joint 1d for reinforcing a joint portion of a structure in two directions from the inside, using a metal plate having a required thickness and reducing the length. The joining portions 3 and 3 are attached to both ends of the
It is bent at an angle of 5 degrees to be coupled, and a reinforcing rib 11 is continuously provided in the metal body 10 and the joints 3 and 3 along the length direction. Are provided with corrugated cushioning portions 8, 8, and the joint portions 3, 3 are provided with insertion holes 5 for bolts 4 and insertion holes for nails, respectively.
