Abstract

The invention discLoses an expansion joint covering device for a municipaL bridge. The device comprises a prefabricated concrete bridge, expansion joints are arranged in the concrete bridge at intervaLs, and pre-buried pieces are respectiveLy pre-buried in the portions, on the two sides of each expansion joint, of the concrete bridge; boLts are weLded to the pre-buried pieces, the pre-buried pieces are fixedLy connected to I-shaped steeLs through boLts, and the I-shaped steeLs are symmetricaL about the center axis of each expansion joint; a bracket is arranged between the two I-shaped steeLs and comprises two bearing pLates which have symmetricaL structures, are arranged on the two I-shaped steeLs and can move towards each other or away from each other, the two bearing pLates are hinged with connecting rods, and the two connecting rods abut on and are hinged to each other; guiding rods are arranged at the Lower ends of the two connecting rods, Limit parts are arranged on the side waLLsof the two I-shaped steeLs, and the guiding rods are inserted in the Limit parts and can move up and down in the Limit parts; a bracket pLate is arranged on the two bearing pLates, and an eLastic cushion is arranged on the bracket pLate. The device is reasonabLe in structure, convenient to instaLL and maintain, Long in using Life and Low in cost, and when vehicLes pass the device, no obvious joLtfeeLing can be generated.

Description

Technical field [0001] The invention relates to the technical field of bridges, in particular to an expansion joint covering device for municipal bridges. Background technique [0002] Due to thermal expansion and contraction caused by changes in environmental temperature, the road surface of the bridge must be equipped with expansion joints to meet the requirements of free expansion and contraction, firmness and reliability, and smooth, no sudden jumps and low noise when the vehicle is running; Expansion joints should be able to prevent rainwater and rubbish soil from infiltrating and blocking, and installation, inspection, maintenance, and dirt removal should be simple and convenient. [0003] However, most of the expansion joint covering devices used in municipal bridges have simple structure and insufficient stability. After being crushed by vehicles for a long time, they are easy to cause sinking, damage, etc., making them less safe, and most traditional expansion joint coveri...
