A bridge pier anti-overturning structure

Abstract

The invention discloses an anti-overturning structure of a bridge pier, which comprises a mounting base plate, which is fixedly connected to the platform body through bolts; through the matching of the socket corresponding to the bridge support and the connecting boss, the limit installation of the bridge support is carried out , and through the top-down plug-in installation, the installation of the bridge support is convenient and the installation is guaranteed in place. By setting the steel ball block, the steel ball block supports the bridge support through the trapezoidal block and the top plate. When the eccentric overload suddenly occurs When the bridge bearing is suddenly overloaded, a slight deflection deformation occurs. At this time, the bridge bearing follows the top plate and the trapezoidal block through the steel ball block to perform a slight rotation in the direction of deflection, and then the slight deformation caused by overload is carried out. Partially offset to prevent the hard pressure on the bridge support due to overloading, and at the same time buy more time for the pressure transfer on the bridge surface, reducing the probability of bridge overturning.

Description

technical field [0001] The invention belongs to the technical field of bridges, in particular to a bridge pier anti-overturning structure. Background technique [0002] Bridges refer to buildings built for roads to cross natural or artificial obstacles. Refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations; the auxiliary structures refer to the bridge head abutment, conical slope protection, revetment, diversion works, etc.; bridges are divided according to the structural system, including girder bridges, arch bridges, There are four basic systems of rigid frame bridge and suspension cable bearing (suspension bridge, cable-stayed bridge). [0003] The pier is mainly composed of a top cap and the pier body; the abutment is mainly composed of the top cap and the abutment body; Therefore, the top hat should be constructed with high-strength materials, generally not less than 200-grade reinforced concrete, and the th...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a bridge pier anti-overturning structure to solve the above-mentioned background technology in order to uniformly disperse the pressure of the bridge, it is necessary to ensure that the bridge is properly docked, and at the same time prevent The problem of overturning phenomenon when suddenly subjected to eccentric overload
