Description

Highway expansion joint structure Technical Field The utility model belongs to the technical field of highway expansion joints, and particularly relates to a highway expansion joint structure. Background The butt joint type highway expansion joint is generally composed of steel boundary beams, sealing rubber belts, an anchoring system and the like. The boundary beam is fixed with the bridge or the roadbed through the embedded bars to form a rigid frame, the middle rubber belt is embedded into the boundary beam groove, and the elastic displacement of the road surface is absorbed by using rubber elasticity. The highway expansion joint is exposed in natural environment for a long time, is subjected to wind blowing and rain beating, sun drying and rain spraying and rolling of vehicles, the expansion joint expands with heat and contracts with cold due to the change of temperature and load, rainwater and snow water are easy to permeate along the gap in the repeated expansion process, and the internal metal parts are caused to rust and corrode, so that a highway expansion joint structure is required to be designed, rainwater sundries are prevented, gaps are filled and prevented from being invaded, large particles are prevented, the inside of the expansion joint is kept clean and dry, and the rubber cushion pad absorbs the load impact of the vehicles, so that the stability and durability of the sealing structure are improved. Disclosure of utility model The utility model aims to provide a highway expansion joint structure, which has the advantages of rainwater sundries resistance, joint filling and intrusion prevention, large particle blocking, clean and dry interior of an expansion joint, absorption of vehicle load impact by a rubber cushion pad and improvement of stability and durability of a sealing structure, so as to solve the background technical problem. The technical scheme includes that the highway expansion joint structure comprises a gap formed in a central shaft of a highway, two symmetrical F-shaped side beams are arranged in an inner cavity of the gap, rubber sealing strips are arranged on one sides of two F-shaped sides Liang Xiangxiang, rubber sealing strips are arranged at the gaps of the tops of the two F-shaped side beams, the front side and the rear side of the rubber sealing strips are attached to the front side and the rear side of the two F-shaped side beams, the rubber sealing strips are located at the tops of the rubber sealing strips, mounting pressing strips are attached to the left side and the right side of the tops of the rubber sealing strips, rubber buffer pads are arranged on the left side and the right side of the rubber sealing strips, the two rubber buffer pads are arranged on one sides of the mounting pressing strips and the F-shaped side Liang Xiangxiang, the front side and the rear side of the tops of the two mounting pressing strips are fixedly connected with cross beam plates through bolts, and round holes are formed in four corners of the tops of the two gaps.
