Abstract

The invention discloses a bridge deck steel-plastic body expansion device belonging to the technical field of bridge construction. The bridge deck steel-plastic body expansion device comprises a roadway expansion device and a sidewalk or a guardrail expansion device, a cross gap supporting structure forms a long groove shape steel structure on an expansion gap, a steel-plastic elastomer is arranged in the long groove shape steel structure and is welded with the long groove shape steel structure into a whole. Two sides of the steel-plastic elastomer are respectively provided with a sideboard, and a reinforcing steel bar is connected between the sideboard and a stop board; force bearing boards are evenly arranged between the stop boards on two sides; an elastic strip is connected between the head and the tail of two adjacent force bearing boards; and spaces formed by sideboards on two sides, the stop board, the force bearing boards and the elastic strip are filled with thermoforming artificial rubber. The bridge deck steel-plastic body expansion device has reasonable design, simple structure, convenient assembly and replacement, long service life, and water, dust and shock prevention, can satisfy normal displacement deformation requirement of a girder, is comfortable to travel and does not jump.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a connecting device for bridge expansion joints. Background technique [0002] In the prior art, expansion joints of bridges are equipped with expansion devices, and these expansion devices have some defects to varying degrees. At present, a large number of Maole expansion devices are used in the joints, which are easy to accumulate dust and stones in the joints, and the car jumps obviously, and is waterproof. The rubber is easy to detach and leak water, and the concrete on both sides of the beam joint is easily damaged by the impact of the vehicle due to jumping. There is no recognized design for the treatment of expansion joints of sidewalks and guardrails, and soft materials are generally used for filling. It is neither beautiful, difficult to waterproof, and easy to fall off. Contents of the invention [0003] Aiming at the above-mentioned deficien...
