Bridge modular telescopic device anchoring structure

Abstract

The invention discloses a bridge modular telescopic device anchoring structure, which belongs to the technical field of bridge structure telescopic devices, and comprises a side beam, a connecting steel plate, horizontal round bars, an annular steel, an embedded bar, a supporting beam box body and a displacement box body, wherein the connecting relationship is as below: the connecting steel plate is arranged on the side beam; the two horizontal round bars penetrate through the connecting steel plate and are fixed with the supporting beam box body or the displacement box body; the annular steel penetrates through the two horizontal round bars and can freely move along the horizontal round bars; the annular steel is welded with the embedded bar. According to the bridge modular telescopic device anchoring structure, free telescoping can be realized, the service life of the modular telescopic device is improved, and the safety problem of driving a car on a bridge caused by the damage of the telescopic device is avoided.

Description

technical field [0001] The invention belongs to the technical field of expansion devices for bridge structures, and in particular relates to an anchoring structure for bridge modular expansion devices. 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 device is as...
