Abstract

The invention provides a single-joint adjusting device for a bridge expansion joint. The single-joint adjusting device for the bridge expansion joint comprises a right side adjusting block, a left side adjusting block, an active adjusting screw rod, a driven adjusting screw rod and a transmission gear. The single-joint adjusting device for the bridge expansion joint has the advantages that the adjusting demands of the expansion joint in the making and mounting process are met, the adjusting is convenient and fast, and the accuracy is high.

Description

technical field [0001] The invention relates to a gap adjustment device, in particular to a bridge expansion joint single seam adjustment device. Background technique [0002] Bridge expansion joints: refers to the expansion joints usually set between two girder ends, between the girder end and abutment or at the hinged position of the bridge in order to meet the deformation requirements of the bridge deck. Where expansion joints are set, railings and bridge deck pavement must be disconnected. The role of bridge expansion joints is to adjust the displacement and connection between the superstructure caused by vehicle loads and bridge building materials. However, the existing expansion joints have high cost, low efficiency and time-consuming technical problems in the process of manufacture and installation. Therefore, it is necessary to design a device that can easily adjust the size of the expansion joints of the bridge to meet the adjustment needs of the expansion joints ...
