Abstract

The invention belongs to the field of seismic absorbing and seismic insulating and relates to a self-resetting energy-consuming connection device. The device is characterized in that an upper wing plate, a lower wing plate and a ventral plate form a fixing structure, each of the upper wing plate, the lower wing plate and the ventral plate is provided with a guide groove, crossbeam connecting rods are connected with arc-shaped elastic plates, friction hinged seats are arranged on the end portions of the arc-shaped elastic plates and hinged to the arc-shaped elastic plates, the friction hinged seats on two sides of the ventral plate are connected by applying designed pretightening force through bolts, and guide columns are arranged at positions, corresponding to the guide grooves of the upper wing plate and the lower wing plate, of the arc-shaped elastic plates. The self-resetting energy-consuming connection device is simple and easy to manufacture and convenient and quick to mount; the device is mounted between a beam body and an abutment through the crossbeam connecting rod, and relative displacement of the beam body and the abutment is not limited under normal circumstances; under seismic action, the device can connect the beam body and the abutment into a whole to reduce seismic reaction through energy consuming and can realize self-resetting after an earthquake.

Description

technical field [0001] The invention relates to a self-resetting energy-consuming connection device, in particular to a self-resetting energy-consuming connection device based on a protection function, which is suitable for shock absorption of beams and columns of bridges and structural buildings, and can make the structure cooperate under the action of a sudden earthquake force and improve the overall seismic performance of the structure. Background technique [0002] my country is an earthquake-prone country, and the previous earthquake damages have promoted the improvement and development of the structural seismic system, but there are still various defects in the seismic performance of existing structures. During the construction of existing continuous girder bridges, although shock-absorbing measures such as shock-absorbing and isolation bearings and viscous dampers have been taken to reduce the seismic response of the bridge and improve the seismic performance of the b...
