Embodiment 1

[0020] Such as Figure 1 to Figure 4 As shown, a number of shear energy-dissipating layer limiting devices of the present invention are arranged around the base isolation structure 13, corresponding to the positions of the base isolation support 10 one by one, and the shear energy-dissipating type of the present invention The limit baffle 8 of the shock-isolation layer limit device is fixed on the reaction wall 11, and the elastic anti-collision damping material 6 is kept at an appropriate distance from the frame column or the shear wall 9 connected to the upper part of the base shock-isolation support 10, which is less than It is equal to the ultimate horizontal displacement of the base shock-isolation bearing 10.

[0021] When the earthquake causes a large horizontal displacement of the isolation layer, the upper frame column or shear wall 9 of the isolation support contacts the elastic anti-collision damping material 6, and the force is transmitted to the side anti-collisio...

Abstract

The invention provides a shearing energy dissipation type shock insulation layer limiting device, and belongs to the field of engineering structure seismic isolation and energy dissipation seismic mitigation. Elastic anti-collision damping material (6) is bonded to a side anti-collision plate (5) which is perpendicularly fixed to a shearing steel plate (3), two sides of the shearing steel plate (3) are bonded to damping material layers (2), an upper connecting steel plate (1) is bonded to the damping material layer (2) on the upper side, a lower connecting steel plate (4) is bonded to the damping material layer (2) on the lower side, the lengths of the upper connecting steel plate (1) and lower connecting steel plate (4) are both larger than the length of the damping material layers (2), shearing screws penetrate the upper connecting steel plate (1) and the lower connecting steel plate (4), and the other ends of the upper connecting steel plate (1) and lower connecting steel plate (4) are connected to a limiting baffle (8). By the aid of the device, safety of a base isolation system under the action of near-fault earthquakes is improved.

Description

technical field [0001] The invention relates to a shear energy consumption type seismic isolation layer limit device, which belongs to the technical field of engineering structure isolation and energy consumption vibration reduction, and is mainly used for seismic isolation of buildings and bridges in near-fault earthquake areas after adopting basic seismic isolation technology Layer limit protection. Background technique [0002] Earthquake is a sudden natural disaster that endangers people's lives and properties. The basic seismic isolation technology absorbs seismic energy by setting a seismic isolation layer, thereby reducing the seismic energy entering the upper structure. The basic seismic isolation structure has a good seismic isolation effect in the teleseismic area, and has withstood the test of earthquakes in many earthquakes. However, in near-fault earthquake areas, due to the particularity of near-fault earthquakes, the horizontal displacement of the isolation l...
