However, Japanese Patent Application Laid-Open No. 10-169210 discloses
No. 3046700 and the seismic reinforcement device of Utility Model Registration No. 3046700 are designed to buffer only the load applied to the vertical fixing direction between the foundation fixing member and the upper fixing member among the loads generated by both members due to the earthquake. If a load is generated in a direction in which the two members move left and right and back and forth, and in a direction in which the two members swing right and left and back and forth, the load cannot be buffered. Further, in the seismic retrofitting device of No. 3058888, since the elastic member is sandwiched between the plates provided in the vertical direction and the front-rear direction, the load can be buffered not only in the vertical direction but also in the front-rear direction. Since the member is inserted between the plates from the left and right, there is a disadvantage that when a large load is applied in the left and right direction, the load cannot be buffered.

According to the seismic retrofitting device of the fifth aspect, when a load is generated between the first connecting portion and the second connecting portion in a direction in which the loads are separated from each other in the up-down direction, the inner cylindrical portion is connected to the inner connecting portion. The load is buffered by the elastic member disposed in the gap with the outer cylinder. Further, since the inner cylindrical portion and the outer cylindrical portion are locked via the elastic member, it is possible to prevent the column from coming off the base due to a load due to an earthquake. Further, the inner cylindrical portion and the outer cylindrical portion are locked not only in the vertical direction but also in the horizontal direction or a combined direction thereof. further,
The rotation suppressing portions provided on the first connecting portion and the second connecting portion can suppress the movement of the inner cylinder portion and the outer cylinder portion in the relative rotation direction. Thereby, the movement and the swing of the column and the base in the left-right direction or the combined direction of up-down and left-right can also be suppressed. When the inner cylinder portion and the outer cylinder portion are formed in a rectangular tube shape such as a square, a hexagon, or an octagon, the rotation suppression portion is configured to inhibit the rotation of the inner cylinder portion and the outer cylinder portion.

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.

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.
