Abstract
The utility model belongs to the technical field of bridge supports, and discloses a seismic mitigation and absorption support. The seismic mitigation and absorption support is characterized by comprising an upper base board, a first ultra-high molecular weight polyethylene board, a middle board, a second ultra-high molecular weight polyethylene board and a bottom board from top to bottom, wherein a pulling-resistant drawing edge is arranged on the lower surface of the upper base board and close to the periphery, the upper surface and the lower surface of the middle board are a central concave spherical surface and a central convex spherical surface respectively, and a spherical convex core matched with the central concave spherical surface is arranged on the inner side of the pulling-resistant drawing edge. The upper surface of the bottom board is a bottom board concave spherical surface matched with the central convex spherical surface, an upper pulling-resistant convex ring is arranged at a position, close to the upper side, of the side face of the middle board, a lower pulling-resistant convex ring is arranged at a position, close to the lower side, of the side face of the middle board, a pulling-resistant press ring is arranged on the outer side of a position above the lower pulling-resistant convex ring, and the pulling-resistant press ring is fixed on the bottom board. When low-magnitude earthquakes occur, the press ring and the bottom board achieve pulling-resistant and shearing-resistant functions. When high-magnitude earthquakes occur, the press ring is damaged by the middle board in a pulled mode, the middle board conducts pendulum movement in the bottom board, energy consumption and seismic absorption are achieved, and damage, to a bridge, caused by the earthquakes is reduced.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates to a kind of vibration absorption and isolation support concretely.
Background technology
In the bridge pad field, shearing resistance and resistance to plucking ability in order to increase bearing are designed to the resistance to plucking spherical bearing, comprise upper base plate, ball core and have the base plate on basin edge, have the resistance to plucking flanging at upper base plate.When earthquake took place, this bearing power consumption and damping effect were poor, and bearing is damaged.In order to increase power consumption and damping effect, people adopt the hyperboloid bearing, but this bearing shear behavior is poor.
