Prefabricated bridge panel expansion joint connecting member

Abstract

The invention discloses a prefabricated bridge panel expansion joint connecting member, and belongs to the technical field of expansion joint connecting members. The prefabricated bridge panel expansion joint connecting member comprises a plurality of sub-members arrangedin the length direction of expansion joints, vertical supporting blocks are arranged in acontaining cavity formed by oppositelyarranging the opening ends of a first U-shaped fastener and a second U-shaped fastener of the sub-members, buffer mechanismsare symmetrically arranged on the left sidesand the right sides of the vertical supporting blocks,elastic filler layersarearranged between two vertically adjacent profiled steel sheet assemblies as well asbetween the profiled steel sheet assemblies and the first U-shaped fastener as well as betweenthe profiled steel sheet assemblies and the second U-shaped fastener,L-shaped through grooves are formed in the overlapping portion of the first U-shaped fastener and the secondU-shaped fastener, fastening bolts are arranged in the L-shaped through grooves, vertical through holes are formed in the vertical supporting blocks, screwed pipes are pre-embedded at the bottoms ofthe expansion joints, and the lower ends of the fastening bolts penetrate through the L-shaped through grooves and the vertical through holes to be connected with the screwed pipes. The prefabricatedbridge panel expansion joint connecting member has the characteristics of being high in toughness, high incapacity forresistingexpansion joint deformation, and capable of realizingtimesaving and laborsaving in installation and maintenance.

Description

technical field [0001] The invention relates to the technical field of expansion joint connection components, in particular to a prefabricated bridge deck expansion joint connection component. Background technique [0002] Bridge expansion joints refer to expansion joints usually set between two girder ends, between girder ends and abutments, or at the hinged position of the bridge in order to meet the deformation requirements of the bridge deck. The function of bridge expansion joints is to adjust the displacement and connection between the superstructure caused by vehicle loads and bridge construction materials. Once the telescopic device of the bridge is destroyed, it will seriously affect the speed, comfort and safety of driving, and even cause driving safety accidents. However, the current traditional expansion joint connection components have the problems of poor toughness and weak resistance to deformation on the one hand, and problems such as difficult installation ...

AI Technical Summary

Problems solved by technology

Once the expansion device of the bridge is damaged, it will seriously affect the speed, comfort and safety of driving, and even cause driving safety accidents

However, on the one hand, the traditional expansion joint connection components have the problems of poor toughness and weak resistance to deformation; on the other hand, they also have the problems of difficult installation and maintenance, low efficiency, and high maintenance costs.
