Highway bridge expansion joint device

Abstract

The invention discloses a highway bridge expansion joint device, and belongs to the technical field of highway bridge construction. The highway bridge expansion joint device comprises a first steel plate and a second steel plate, wherein the first steel plate and the second steel plate are oppositely arranged, a first groove is formed in the first steel plate, and a second groove opposite to the first groove is formed in the second steel plate; a plurality of first upper connecting grooves and first lower connecting grooves are formed in the first groove, and a plurality of second connecting grooves and second lower connecting grooves are formed in the second groove; and the first upper connecting grooves are connected with corresponding second upper connecting grooves through first shockabsorption devices, second shock absorption devices are arranged right below the first shock absorption devices, inclined directions of adjacent two second shock absorption devices are different, anda water-stop belt is arranged above the first shock absorption devices. According to the highway bridge expansion joint device, the structure is simple, the installation and the maintenance are convenient, the phenomenon of skip motion of a vehicle can be effectively avoided, the overall structural stability is good, the impact is effectively relieved by the collaborative deformation of the two steel plates, the service life of the whole expansion joint is prolonged, and the highway bridge expansion joint device has good economical efficiency.

Description

technical field [0001] The invention relates to the technical field of highway bridge construction, in particular to a highway bridge expansion joint device. Background technique [0002] With the take-off of my country's economy, infrastructure construction has also achieved unprecedented development. The number of highway bridges in our country has become countless. The expansion joints of highway bridges are structures and devices designed when building highway bridges. Factors can be freely expanded and contracted. However, the current expansion joints of highway bridges are mostly rubber steel plate structures, and the on-site cast-in-place expansion joints are complicated to operate, which wastes manpower and material resources. Generally, when the rubber steel plate structure expansion joints respond to vehicle impacts, the car jumping phenomenon is serious, causing a lot of noise; and the vehicle impact Cause damage to expansion joints, and then cause damage to the m...
