Anti-seismic support structure of bridge

Abstract

The invention relates to an anti-seismic support structure of a bridge. The novel anti-seismic and shock-absorbing support structure is a novel anti-seismic and shock-absorbing support structure adopting a steel composite plastic product. A square notch is formed in the center of the bottom of the workpiece bottom plate, and second buckles are arranged on the two sides of the workpiece bottom plate; a concave bending workpiece and a convex bending workpiece are cast on the workpiece bottom plate, and a U-shaped groove is formed between the concave bending workpiece and the convex bending workpiece. A first buckle is arranged at the top end of the convex bent workpiece. According to the technical scheme that the concave bent workpiece, the convex bent workpiece and the workpiece bottom plate are integrally cast to form the anti-seismic support single modules, and the multiple anti-seismic support single modules are all penetrated by the tough plastic rods, and the steel-plastic composite mode is adopted structurally; while the advantages of plastic rubber characteristics are reserved, a steel casting structure is used for wrapping, so the performance of the rubber block is much better than that of a conventional single rubber block in structure.

Description

technical field [0001] The invention relates to an anti-seismic bearing structure of a bridge. Background technique [0002] With the development of the economy, the scale of the city continues to expand, and the traffic volume in the city is increasing. The fatigue of concrete has become a problem that cannot be ignored. In order to meet the development of heavy-duty vehicle transportation, the bridges on the urban transportation line need to undertake the transportation task of large and heavy equipment. The impact of overloaded vehicles on the fatigue performance of concrete in existing reinforced concrete bridges has become an urgent concern. Therefore, it is easy to cause damage between the bridge and the main body of the pier column, and easy to produce cracks between the main body of the beam body and the adjacent road surface. This is due to the unreasonable design of the seismic bearing structure of the bridge, or there is no relevant design in this regard; at pres...

Therefore, it is easy to cause damage between the bridge and the main body of the pier column, and easy to produce cracks between the main body of the beam body and the adjacent road surface. This is due to the unreasonable design of the seismic bearing structure of the bridge, or there is no relevant design in this regard; at present The earthquake resistance of traditional bridges is directly cushioned by rubber blocks, but this itself has defects in the material structure, and its durability will cause aging damage with the passage of time. Therefore, the simple rubber blocks reduce the Shock unreasonable
