An anchoring method and anchoring structure of a bridge modular expansion device

Abstract

The invention discloses a bridge modular pattern telescopic device anchoring method and structure. According to the anchoring structure, a connecting steel plate is arranged on a side beam of a modular pattern telescopic device, two pieces of horizontal circular steel penetrate through the connecting steel plate, the two pieces of horizontal circular steel and a supporting beam box body or a displacement rod box body are fixed, an adjustable anchoring steel plate with a circular hole penetrates through the two pieces of horizontal circular steel and can move freely along the horizontal circular steel, the adjustable anchoring steel plate and an embedded steel rib are welded, meanwhile, U-shaped anchoring steel ribs are welded on the two sides of the supporting beam box body or the displacement rod box body, two horizontally-penetrating steel ribs are arranged, meanwhile, the steel ribs penetrate through the embedded steel rib and the U-shaped anchoring steel ribs, and anchoring of the horizontal supporting beam box body or the displacement rod box body and the embedded steel rib is achieved. The problems that in the prior art, the bridge modular pattern telescopic device is poor in anchoring performance, mounting is hard, and service life is not ideal are solved.

Description

technical field [0001] The invention relates to an anchoring method and an anchoring structure of a bridge modular expansion device, belonging to the technical field of bridge structure 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...
