The invention relates to a bridge expansion joint device, which includes a fixed comb and a movable comb. A telescopic support device placed between the bridge expansion joints is connected under the fixed comb and the movable comb. The telescopic support device includes multiple A telescopic connecting beam and a plurality of crossbeams, a plurality of telescopic connecting beams and a plurality of crossbeams form a supporting device at the upper part of the gap of the expansion joint, support the position of the movable comb above the gap, and avoid the deformation of the movable comb. The present invention is compatible with bridge expansion joints There are only a few expansion joint beams set at intervals at the joints, and there is no need to deal with the entire expansion joint. The requirements for the regularity of the expansion joint are low, and it is suitable for the installation of large-scale bridge expansion joints.
Description
technical field [0001] The invention relates to bridge expansion joints, in particular to a bridge expansion joint device. Background technique [0002] Bridge expansion joints refer to the installation of expansion joints between two girder ends, between girder ends and abutment or at the hinge position of the bridge in order to meet the deformation requirements of the bridge deck. All directions can be freely expanded and contracted, firm and reliable, and the vehicle should run smoothly without sudden jumps and noises; it should be able to prevent rainwater and garbage from infiltrating and blocking; installation, inspection, maintenance, and removal of dirt should be simple and convenient. [0003] The patent document with the application number CN200410066942.6 discloses a comb-type bridge expansion joint device that resists lateral displacement, including fixed combs and movable combs that are respectively arranged on the beam bodies on both sides of the bridge expansi...
