Aseismic structure between bridge pier and bridge plate

Abstract

The invention discloses an aseismic structure between a bridge pier and a bridge plate. The aseismic structure comprises a cross beam disposed on the top of the bridge pier and the bridge plate located above the cross beam. Convex blocks are arranged on the lower portion of the bridge plate, and concave pits corresponding to the convex blocks are formed in the upper portion of the cross beam. Eachconcave pit is internally provided with left and right lifting faces, wherein the lifting faces are used for lifting the convex blocks to convert kinetic energy into gravitational potential energy when the convex blocks move laterally; each convex block is located in the corresponding concave pit. According to the aseismic structure between the bridge pier and the bridge plate, the energy for horizontal vibration can be effectively converted and dissipated to avoid the situation that the relative displacement between the upper bridge plate and the lower cross beam is too large due to horizontal vibration, and therefore the bridge structure is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of bridge anti-seismic construction, in particular to an anti-seismic structure between a bridge pier and a bridge plate. Background technique [0002] For bridges with reinforced concrete structure, a beam is generally poured on the upper end of the pier, and the bridge deck rests on the beam. Although the reinforced concrete structure bridge can withstand the horizontal force of the earthquake in terms of design strength, because the connection between the upper bridge deck and the lower beam and pier is not firm and the integrity is poor, it often fails due to various reasons such as the horizontal force of the earthquake, When the horizontal vibration is caused by the impact force of the hull on the bridge pier, the impact force of the water flow on the bridge pier when the water rises, and the impact force of the hull on the bridge plate after the water level rises, there will be excessive relative disp...
