Abstract

The invention relates to a building expansion and retraction device, and provides an expansion and contraction device with an arch elastic connection function. The expansion and contraction device comprises two edge beams located on the two sides of an expansion joint and arranged oppositely, and further comprises a rubber strip which is clamped between the two edge beams and stretches across the expansion joint. At least one elastic connecting plate is further arranged below the rubber strip, the elastic connecting plates are sequentially arranged at intervals in the length direction parallel to the expansion joint and fixedly connected to the two edge beams through anchor bolts, and each elastic connecting plate stretches across the expansion joint and vertically supports the rubber strip. According to the expansion and retraction device, the rubber strip is adopted for waterproof sealing between the two edge beams, the elastic connecting plates located below the rubber strip are used for supporting the rubber strip, a certain reverse acting force can be provided for the rubber strip, the reliability of the rubber strip can be improved, and the rubber strip is not likely to disengage from the edge beams; besides, the elastic connecting plates can play a role similar to that of elastic connecting hinges, so that the left edge beam and the right edge beam bear force cooperatively, and the structural integrity of the expansion and retraction device is improved.

Description

technical field [0001] The invention relates to expansion devices for bridges and other buildings, in particular to an expansion device with arcuate elastic connections. Background technique [0002] The telescopic device is a key part of the bridge components and plays an important role in realizing the bridge function. The national standard "Road Engineering Terminology Standard" (GBJ124-1988) and the traffic industry standard "Highway Engineering Terminology and Structural Terminology" (JTJ 002-87) define the expansion device of the bridge as: in order to make the vehicle pass the bridge deck smoothly and meet the bridge deck structure Deformation needs, the general term for devices installed at bridge deck expansion joints. [0003] At present, the commonly used bridge expansion devices can be divided according to the system: ①Modular bridge expansion device; , Modular comb plate type multi-directional displacement bridge telescopic device, etc. "Highway Bridge Expans...
