Description of the Related Art Conventionally, a wooden building of this type is composed of three parts, a hut assembly as a framework of a part above and below a ceiling, a skeleton as a framework for forming a wall, and a floor assembly for forming a floor. It has been. For example, in a floor set, a pillar is vertically connected to and fixed to a base which is a structural member. In such a connection portion between the base and the column or a connection portion between the eaves girder, in order to further strengthen the connection and fixation, a strip-shaped bolt is attached to the other end of a threaded round steel bar called a blade bolt. It is common to attach a reinforcing metal with a steel slab to reinforce the connecting and fixing part. This Hakodate bolt is
The steel slab is fixed to the lower end of the column with a bolt or the like, a round steel bar is penetrated through the base, and a nut is screwed to the lower end and fixed.

[0003]

By the way, as described above, when the respective structural members are rigidly connected with the blade bolts, when the wooden structure vibrates due to the earthquake, the vibration cannot be completely absorbed and the wooden structure is damaged. I had to give. For example, when the column is bent, if the base and the column are rigidly connected with the blade bolt, a gap is created between the wall and the column due to the bending,
Sliding doors could not be opened and closed. Also, when the column was tilted by the vibration, even if the wall cracked, the tilt could not be restored.

An object of the present invention is to solve such a problem.

[0005]

In order to achieve the above object, the present invention takes the following measures. That is, the seismic connection member of the wooden structure according to the present invention is configured to be fixed to one structural member and elastically connected to the other structural member.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a seismic connecting member for connecting structural members crossing each other in a wooden structure, and has a flat portion at one end which is fixed in close contact with one structural member. An earthquake-resistant connecting member for a wooden structure, comprising: a main body member; and an elastic connecting member for elastically connecting the main body member to another structural member.

In such a configuration, the main body member is fixed to one of the structural members, and the main body member is connected to the other structural member via the elastic connecting member.
When a vibration acts on one of the structural members, the elastic connecting member acts so as to absorb the vibration. For this reason, one of the structural members is flexibly changed with respect to the vibration, and damage at the intersection can be minimized. In other words, it is possible to prevent one structural member from moving away from the other structural member, and to suppress a movement in which one structural member presses the other structural member.

In order to achieve both vibration absorption and reliable connection between the structural members, the elastic connecting member has a screw body having a size penetrating the other structural member, and the screw member penetrates the main body member and the other. And a nut member for fixing an end portion of the screw body to the main body member. With this configuration, the structural members are formed by the screw body and the nut member via the main body member, and the elastic body is interposed between the main body member and the other structural member. The two structural members are connected to each other, and the vibration can be absorbed by the elastic body.

In order to effectively absorb the vibration, it is preferable that the elastic body is a compression coil spring having an inner diameter through which the screw body can pass. Thus, by using a compression coil spring, when one structural member is inclined with respect to the other structural member, the inclination can be minimized. In addition, as the elastic body,
Examples thereof include a cylindrical hard rubber and a compression-type coil spring that is fixed to have an inner diameter through which a screw body can penetrate. By combining such a hard rubber and a compression coil spring, they cooperate with each other, so that they effectively act even on a large vibration.
