Modular multidirectional displacement telescopic device and bridge

Abstract

The invention relates to building telescopic devices and provides a modular multidirectional displacement telescopic device which comprises a joint crossing beam and one or more comb plate assemblies, wherein the joint crossing beam comprises a supporting panel, two steel ball supports and at least one cambered surface support seat plate; the two steel ball supports and the cambered surface support seat plate are respectively positioned on the two sides of a structural joint; one steel ball support is a fixed support and the other steel ball support is a bi-directional movable support; the comb plate assemblies are arranged on one side of the joint crossing beam in sequence; adjacent comb plate assemblies are connected through rigid body elastic elements; the invention further discloses a bridge; the bridge comprises the telescopic device. The joint crossing beam of the telescopic device provided by the invention mainly eliminates influences generated by the angle rotation and displacement in the vertical direction and the comb plate assemblies and the rigid body elastic elements can eliminate influences of the bridge stretching and retraction change generated in the direction along the bridge and angle rotation in the cross-bridge direction, three-directional displacement, stretching and retraction, and rotation of the bridge caused by temperature, wind force and loads can be met, a continuous traffic bearing surface can be provided for vehicle running and noise reduction and vibration prevention effects are good.

Description

technical field [0001] The invention relates to bridges and other building expansion devices, in particular to a modular multi-directional displacement expansion device and a bridge. Background technique [0002] The telescopic device is a key part of the bridge components and plays an important role in realizing the bridge function. Common bridge expansion devices include plate rubber expansion devices, steel modular expansion devices, and comb-tooth plate expansion devices. [0003] During the construction and operation of the bridge, it will be subjected to vehicle loads, shrinkage and creep of the bridge's own materials, foundation settlement, wind load, etc., causing deformation of the bridge beam end. There are different degrees of spatial movement in the bridge structural joints in the six degrees of freedom (displacement and torsion in the three directions of XYZ), which will cause extrusion, stretching, torsion, dislocation, settlement and other spaces for the tele...
