Abstract

The invention discloses a bolt-free prepressing type large-displacement anti-deflection multidirectional displacement comb plate bridge expansion device, belonging to the technical field of bridge construction. The bridge expansion device comprises comb plates fixedly connected with a beam body and a supporting mechanism arranged under the comb plates. The key points are as follows: the bridge expansion device further comprises a middle comb plate arranged between the two comb plates, the supporting mechanism comprises supporting displacement boxes fixed to the lower portions of the comb plates and supporting cross beams arranged in the length direction of the beam body; the number of the supporting cross beams is at least two, all the supporting cross beams are arranged in the width direction of the beam body and fixed together through supports, the two ends of the middle comb plate are connected with the comb plates at the corresponding ends in an inserted mode respectively, and a positioning plate is fixed to the side face of the middle comb plate and connected with the supporting cross beam located on the outermost side through a connecting piece. The overall deflection resistance and multidirectional deflection capacity of the bridge expansion device can be improved, and vehicles can pass stably.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and relates to a bridge expansion device, in particular to a bolt-free pre-compression type large-displacement anti-deflection multi-directional displacement comb-shaped plate bridge expansion device. Background technique [0002] A bridge expansion joint is a structural joint set on a bridge to prevent the bridge from cracking or being damaged due to climatic temperature changes (thermal expansion, cold contraction), so that the bridge can be horizontally expanded along the length direction. A device is used to connect the build seam. In the existing bridge expansion device, two comb-tooth plates are generally arranged between two adjacent beam bodies. When the distance between the beam bodies is large, the length of each comb-tooth plate is longer, and the insertion of the two comb-tooth plates is relatively long. The connection length is also long, which will affect the overall de...
