Modular intelligent bridge expansion joint

Abstract

The invention relates to a modular intelligent bridge expansion joint, which comprises anchoring bars, side beams, middle beams, cross beams, rubber sealing strips and a displacement control box, wherein the anchoring bars are welded on the side beams, the upper parts of the side beams are in rigid connection with a bridge, the lower parts of the side beams are provided with the cross beams, lower part main bodies of the cross beams are provided with supporting hanging frames, the lower edges of the cross beams are glidingly arranged in the displacement control box, the middle beams are supported by the cross beams arranged at the lower parts of the middle beams, and the rubber sealing strips are embedded into the grooves of the side beams. When the technical scheme of the modular intelligent bridge expansion joint is adopted, a load bearing structure and a displacement control system are separated, the load bearing structure and the displacement control system do not interfere each other during stressing, the safety during the stressing is ensured, the number of the cross beams is reduced, the size of the displacement control box is reduced to the minimum range, steel materials are saved, and the adaptability to bent bridges, slope bridges, inclined bridges and wide bridges is high.

Description

technical field [0001] The invention relates to the field of new material bridges, in particular to a modular intelligent bridge expansion joint. Background technique [0002] When the seasons change, when the girder body of a general road or railway bridge is displaced due to factors such as temperature difference, each group of steel girders in the upper part will open or close at unequal distances through the movement of the supporting beams, and the grooves on the side of the steel girders will continue to change. , leading to fluctuations in its bearing capacity, water seepage, accumulation of dust and debris, and uneven bridge deck distortion. The structural reason is generally that the load-bearing structure and the displacement control system are not separated. It is very unfavorable in a volume scaling environment. Contents of the invention [0003] The purpose of the present invention is to overcome the problems existing in the prior art and provide a modular in...
