Abstract

The invention discloses an expansion device with adjustable steel plate anchoring members, which belongs to the technical field of bridge structure expansion devices. The expansion device comprises side beams, a middle beam, supporting crossbeams, elastic displacement components and side beam-anchoring components. The connection relation of the expansion device is as follows: the side beam-anchoring components are arranged on the side beams, meanwhile, U-shaped anchoring rebars are welded at both sides of each supporting beam box or displacement rod box, two traversing rebars are arranged to penetrate through both precast rebars and the U-shaped anchoring rebars, so the transverse supporting beam box or displacement rod box is connected with the preburied rebars and anchored; the middle beam is supported on the supporting beam boxes, and is connected with the supporting crossbeams through fixing bolts, and the elastic displacement components are fixed with the side beams or the middle beam through the displacement rod boxes. The mounting efficiency of the module expansion device for bridges can be increased.

Description

technical field [0001] The invention belongs to the technical field of expansion devices for bridge structures, and in particular relates to an expansion device with adjustable steel plate anchoring components. Background technique [0002] With the development of my country's transportation construction, the proportion of bridge engineering in expressway is constantly increasing. As the main accessory component of bridge, bridge expansion device is one of the key structures to ensure the safety of bridge operation and the smooth flow of highway. Among them, the modular expansion device is a kind of expansion device that is widely used at present. However, the current situation of the use of the existing modular expansion device shows that the damage phenomenon of the expansion device is very prominent, and the frequency of replacement is frequent, which brings safety hazards to the highway operation and society. Economic losses. The damage form of the modular expansion dev...
