Centralized drainage comb type bridge expansion device

Abstract

The invention relates to the technical field of bridge expansion joints and discloses a centralized drainage comb type bridge expansion device comprising a first face plate. A second face plate is hinged to the right side of the first face plate. The tops of the first face plate and the second face plate are both provided with locating grooves. The inner bottom walls of the two locating grooves are both provided with threaded grooves. Anti-skidding mats are movably installed in the locating grooves. Fixing holes are formed in the anti-skidding mats. According to the centralized drainage comb type bridge expansion device, by forming limiting grooves in stabilizing blocks and installing limiting bars in the limiting grooves, the purpose of limiting a water guiding frame is achieved; by installing the water guiding frame on the limiting bars and installing water drainage pipes on the water guiding frame, when rainwater is leaked from the seam between the first face plate and the second face plate, the rainwater can fall into the water guiding frame, the water guiding frame can guide the water into the water drainage pipes on the front and back two sides, and then the purpose for convenient centralized drainage is achieved.

Description

technical field [0001] The invention relates to the technical field of bridge expansion joints, in particular to a centralized drainage comb-tooth bridge expansion device. Background technique [0002] Bridge expansion joints refer to expansion joints that are usually set between two girder ends, between girder ends and abutment or at the hinged position of the bridge in order to meet the deformation requirements of the bridge deck. In all directions, it can be freely expanded and contracted, firm and reliable. When the vehicle is passing by, it should be smooth and free of sudden jumps and noises. It should be able to prevent rainwater, garbage and soil from infiltrating and blocking. Installation, inspection, maintenance and removal of dirt should be simple and convenient. At the joints, the railings and bridge deck pavement must be disconnected. [0003] The main function of bridge expansion joints is to adjust the displacement and connection between the superstructure c...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a centralized drainage comb type bridge expansion device, which has the advantages of good anti-skid effect and convenient centralized drainage, and solves the problem that the top of the bridge expansion joint device is smooth steel Vehicles are prone to slipping in rainy days, which poses a great safety hazard. At the same time, in rainy days, the drainage of the bridge expansion joint device is very scattered, and the rainwater cannot be discharged concentratedly.
