Description
Technical Field
[0001] The utility model belongs to the technical field of bridge construction engineering, and particularly relates to a sealed bridge expansion joint device. Background Art
[0002] A bridge expansion joint is a type of structure that is set between the two beam ends of a bridge, between the beam end and the abutment, or at the hinged position of the bridge. It is used to adjust the displacement between bridge structures caused by thermal expansion and contraction, vehicle loads, or bridge construction materials. A bridge expansion joint device is usually required to be installed at the bridge expansion joint to protect the bridge expansion joint.
[0003] When in use, the existing comb-tooth plate type expansion joints rely on the elasticity of the rubber strips to control the deformation between the bridges. However, the rubber strips are easy to wear. Excessive wear will affect the use of the expansion joints, which may cause the bridges to crack and vehicles to jump when passing by, affecting vehicle driving. The rubber strips need to be replaced. Since the rubber strips are connected to the steel components, the rubber strips need to be pulled during disassembly. During the pulling process, the rubber strips are easily broken in the steel components, making the disassembly process difficult. Since the service life of the steel components is longer than that of the rubber strips, replacing the steel components and the rubber strips together will cause waste. Utility Model Content
