Since the seismic retrofitting device A of the first embodiment is installed in a wooden house as described above, it absorbs a load generated by an earthquake as follows. First, when a load is generated in a direction away from the foundation E and the base F and the column G due to the pitching of the earthquake, the base F and the column G are connected by the upper fixing member 2a. A load in a direction separating from the base F is applied. Here, a foundation fixing member 1a is fixed to the foundation E, and an upper fixing member 2a is fixed to the base F. Accordingly, a load in a direction away from the base fixing member 1a and the upper fixing member 2a is applied. However, the base fixing member 1a and the upper fixing member 2a are elastic members via the first and second connecting portions 4a and 6a. Since the elastic members 16a are connected by the elastic members 16a, the load is buffered, and the movement of the foundation E and the base F in directions away from each other is suppressed.

Even if the earthquake is very large, the locking portion 10 provided at the lower end of the second connecting portion 6a is locked to the lower edge of the first connecting portion 4a. The base fixing member 1a and the upper fixing member 2a do not separate from each other by a distance larger than the gap between the locking portion 10 and the first connecting portion 4a. Furthermore, since the cushioning member 12 is provided on the upper surface of the locking portion 10, the impact is also reduced when the locking portion 10 collides with the first connecting portion 4a.

Further, even if there is a back-and-forth, right-and-left swing, and a back-and-forth and right-and-left swing due to the horizontal shake of the earthquake, the overlapping surface of the first connecting portion 4a and the second connecting portion 6a has a plate-like shape. Since the elastic member 16a is fixed to the connecting portions 4a and 6a, a load in any direction can be buffered by the elastic member 16a.

The base fixing member 1a and the upper fixing member 2
Since a is connected via the elastic member 16a,
The load due to the earthquake does not concentrate on other portions such as the joint with the beam (not shown) on the upper part of the column G. Further, even when vibrations from a road near the wooden house are transmitted to the wooden house and fine vibrations occur between the foundation fixing member 1a and the upper fixing member 2a, such vibrations are generated by the elastic member 16a.
Wood screws 7 and studs 2
Since the vibration is hardly transmitted to 1, the connection state of the wood screw 7 and the stud 21 is favorably maintained.

Furthermore, the seismic retrofitting device A of the first embodiment
As shown in FIG. 2, since the entire device is formed thin in the front-rear direction, for example, a wooden house is surrounded by a fence, and even when the distance between the outer wall and the fence is small, the seismic A reinforcing device A can be installed.

In the first embodiment, the second connecting portion 6a extends downward and overlaps the first connecting portion 4a. However, the present invention is not limited to this, and the first connecting portion 4a extends upward. Second
The connecting portions 6a may be polymerized, or the connecting portions 4a and 6a may be extended and polymerized. Further, the base F and the column G are fixed by the upper fixing member 2a, but the present invention is not limited to this, and the column F may be fixed only to the column G. Even in such a case, the column G and the foundation E are connected to the elastic member 1 with the base F interposed therebetween.
6A, the pillar G can be prevented from coming off the base F.

The elastic member 16a is connected to the first connecting portion 4a.
Although the one formed separately from the first and second connecting parts 6a is used, the one formed integrally with both or one of the first connecting part 4a and the second connecting part 6a may be used. Also, usually, there is a step between the foundation E and the surface of the outer wall H as shown in FIG. 2, but since this step varies from one wooden building to another, a second step is required to cope with the difference in the step. Connecting part 6
A spacer may be inserted between the first fixing portion 5a and the metal plate 18 on the back side of the elastic member 16a and the first connecting portion 4a. In the above embodiment, the locking portion 10 is opposed to the lower edge of the first connecting portion 4a. However, the locking portion 10 protrudes toward the second connecting portion 6a also at the lower edge of the first connecting portion 4a. A unit (not shown) may be provided.
