Road engineering seamless bridge deck expansion joint structure and construction method thereof

Abstract

The invention discloses a road engineering seamless bridge deck expansion joint structure and a construction method thereof, and belongs to the technical field of road bridge decks. The road engineering seamless bridge deck expansion joint structure comprises a joint cover, elastic bodies are attached to the two sides of the top of the joint cover, limiting mechanisms are arranged in inner cavities of the elastic bodies, one sides of the limiting mechanisms are connected with connecting mechanisms, and damping mechanisms are attached to the tops of the elastic bodies. According to the invention, an inserting rod is pre-assembled into one side of the bridge deck through an anchor rod on one side and attached to one side of the bridge deck, a threaded column connected with one side of the inserting rod is moved into a threaded cylinder to drive a limiting block on one side to be clamped into a limiting base, the relative distance between the elastic bodies and the bridge deck is adjusted, and the bridge deck expansion joint connecting requirement is effectively met; the threaded cylinder and the threaded column can be driven to be separated by screwing a wheel disc, and the threaded column and the limiting base are separated after a first sliding rod is pulled to be separated from the limiting block, so that the disassembly and replacement efficiency of the elastic bodies can be remarkably improved, the replacement and maintenance difficulty is reduced, and the bridge construction and maintenance requirements are met.

Description

technical field [0001] The invention belongs to the technical field of road bridge decks, in particular to a road engineering seamless bridge deck expansion joint structure and a construction method thereof. Background technique [0002] During the construction of the bridge deck, in order to meet the thermal expansion and cold contraction expansion needs of the bridge body, a seam at one end is generally set up to limit the expansion. This is the expansion joint body of the bridge. In order to ensure the tightness and durability of the connection of the expansion joint body Generally, it is necessary to use reinforced concrete to repair and smooth the surface to ensure the durable life. [0003] Chinese patent document CN105839532B discloses a bridge expansion joint, which is arranged in the gap between adjacent beam bodies, including: two special-shaped steel side beams, symmetrically fixed on opposite sides of the gap, and both along the width of the beam body Directiona...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the lack of waterproof ability of the bridge expansion joints, the air bag cannot be flushed and erupted after the water liquid is immersed in the air bag, and the axial stress resistance of the air bag to the expansion joint is insufficient, which affects both sides of the expansion joint The ability of shock absorption and buffering makes the expansion joints easy to be damaged by repeated rolling during the driving process of the vehicle. At the same time, it is difficult to replace the airbag, and the top bridge deck needs to be demolished.
