Steel truss girder cable-stayed bridge and damper connecting bracket device thereof

Abstract

The invention relates to the technical field of bridge engineering, and particularly relates to a steel truss girder cable-stayed bridge and a damper connecting bracket device thereof. The damper connecting bracket device comprises a bracket structure, an upper base, a lower base, a damper or a beam tower longitudinal fixing device or a steel truss girder pushing device, wherein the bracket structure is fixedly connected to the outer side of a lower chord node of the steel truss girder; the upper base is fixedly mounted at the bottom of the bracket structure; the lower base is fixedly mountedat the top of the bridge tower cross beam; one end of the damper, the beam tower longitudinal fixing device or the steel truss girder pushing device is hinged to the upper base, and the other end is hinged to the lower base; the beam tower longitudinal fixing device is used for restraining the steel truss girder in the longitudinal direction of the bridge; and the steel truss girder pushing deviceis used for longitudinally moving the steel truss girder along the bridge. The damper connecting bracket device has the advantages of being large in working space, convenient to operate, low in operation safety risk, capable of arranging a plurality of dampers and diverse in function.

Description

technical field [0001] The present application relates to the technical field of bridge engineering, in particular to a steel truss girder cable-stayed bridge and a damper connection corbel device thereof. Background technique [0002] Most modern cable-stayed bridges use floating or semi-floating systems, that is, there is no longitudinal or lateral constraint between the main girder and the tower pier. In order to avoid excessive displacement of the main girder under external effects such as vehicles and earthquakes and endanger the structural safety, dampers are usually installed between the main girder and the tower pier of the cable-stayed bridge to limit the horizontal displacement of the main girder. [0003] For steel truss girder cable-stayed bridges, common dampers are connected through the upper base at the bottom of the main girder and the lower base at the top of the pier or the top of the pylon beam), and the dampers are arranged horizontally, longitudinally or...
