Bionic telescopic device for rapid construction and mounting method thereof

Abstract

The invention relates to a bionic telescopic device for rapid construction and an installation method thereof. The bionic telescopic device comprises a comb plate, a channel steel box, a displacementsystem and an embedded assembly from top to bottom, wherein two sides of an expansion joint are symmetrically arranged, transversely-through arc-shaped grooves are formed at outer ends of the comb plates, longitudinal tooth combs are arranged at inner ends of the comb plates, a longitudinal strip-shaped groove is formed in the middle of each tooth of the comb plate on one side, a protrusion is arranged at the corresponding position of each tooth of the comb plate on the other side, the tooth combs of the two comb plates on two sides of the expansion joint are oppositely arranged in a crossed mode, an outer end of the channel steel box is a boss, an inner end of the channel steel box is a horizontal plane, an inner side of the boss is provided with a transversely-through arc-shaped clampinggroove corresponding to the arc-shaped groove at the outer ends of the comb plates, and the arc-shaped groove of the comb plate is clamped and embedded in the arc-shaped clamping grooves of the channel steel box and can rotate around the axis of the grooves. The bionic telescopic device is advantaged in that the comb plates and the channel steel box are connected through the arc-shaped groove toform a simulated joint structure, so flexible vertical displacement is realized.

Description

technical field [0001] The invention belongs to the field of bridges, and in particular relates to a rapid construction bionic telescopic device and an installation method thereof. Background technique [0002] The expansion device is an important part of the highway bridge pavement. It is mainly used to adapt to the bridge expansion and contraction caused by the temperature expansion of the bridge, the shrinkage and creep of the concrete and prestressed concrete bridge, and the expansion and contraction displacement of the bridge beam structure under load. Displacement to ensure the safety and comfort of vehicles passing on the bridge. [0003] The expansion device of the highway bridge directly bears the repeated impact of the wheel load in the bridge structure, and is exposed to the atmosphere for a long time, and the operating environment is relatively harsh. It is the most vulnerable part of the bridge structure and difficult to repair. A slight defect or deficiency in...
