Description

The present invention relates to a mechanism for connecting a structure such as a bridge and a damper device.

The damper had to be securely fixed to the structure so that it would be effective in the event of an earthquake.

However, if it is fixed securely, if the damper resists with a resistance force that exceeds expectations (when it reaches the stroke end, in the case of a damper with a large speed dependence, etc.), there is a possibility of damaging the damper body and the structure. ..

Therefore, a damper mounting device has been proposed that promptly loses the function of the damper device so as not to damage the bridge body by the damper device and maintains the durability of the entire bridge (see, for example, Patent Document 1). .. Specifically, one end of the damper device is fastened to the main surface on the other end side of the mounting portion of the first bracket installed in the first bridge structure by the first knock-off bolt. Further, the other end of the damper device is fastened to the main surface on the other end side of the mounting portion of the second bracket installed in the second bridge structure by the second knockoff bolt. Further, the first knock-off bolt and the second knock-off bolt are provided with a weak strength portion having a structural strength lower than that of the other constituent members.

Therefore, when an excessive external force acts on the damper device in the extending direction, the weak portion of the strength of the first knockoff bolt is broken, and the fastening state between one end of the damper device and the first bracket is released. On the other hand, when an excessive external force acts on the damper device in the contraction direction, the weak part of the strength of the second knockoff bolt is broken, and the fastening state between the other end of the damper device and the second bracket is released. To. This prevents the damper device from damaging the first bracket, the second bracket, the bridge girder and the pier.

Japanese Patent No. 5695610

However, when the connection state between one end of the damper device and one bracket is released, the other end where the connection state with the other bracket is maintained due to the weight of the damper device is used as a reference. The posture of the damper device is changed so that one of the ends is lowered. For this reason, when restoring the connection state between the damper device and the bracket, for example, when the bridge is installed in a mountainous area, when it is difficult to bring in and install an appropriate machine in the vicinity of the bridge, the damper It becomes difficult to restore its posture so as to raise the one end of the device. In addition, the damper device may come into contact with other objects in the vicinity during the posture change, resulting in damage to the damper device or the object. In addition, if an earthquake that exceeds expectations occurs, the damper will be displaced significantly, and if the damper reaches the stroke end beyond the movable displacement amount, the damper body may be damaged.

Therefore, an object of the present invention is to provide a damper connecting mechanism capable of suppressing a change in the posture of the damper device when the connection state between one end of the damper device and a structure such as a bridge is released.
