Bridge support

Abstract

The invention provides a bridge support. The bridge support comprises an upper support plate, a lower support plate, a horizontal regulating component and a height regulating component and is characterized in that the upper support plate is used for being connected with the bottom of a bridge beam, the lower support plate is used for being connected with a pier, the horizontal regulating componentis used for eliminating the horizontal mounting errors of the bridge beam and the pier, the height regulating component is used for eliminating the vertical mounting errors of the bridge beam and thepier, the horizontal regulating component comprises regulating holes for regulating the horizontal position of the support and positioning parts used for fixing the horizontal position of the support, the regulating holes are arranged in the upper support plate and / or the lower support plate, and the positioning parts are arranged at the regulating holes; the height regulating component is arranged between the upper support plate and the bottom of the bridge beam or between the lower support plate and the pier. The bridge support has the advantages that bridge design elevation and position requirements are satisfied, and the bridge support is high in regulation precision, simple in structure and the like.

Description

technical field [0001] The invention relates to the field of bridge supports, in particular to a bridge support. Background technique [0002] In recent years, in order to ensure the construction quality of roads, bridges and houses and achieve rapid and efficient construction, industrial construction technology has emerged. Construction technology for on-site splicing of prefabricated modules. Industrialized construction techniques include the construction of simply supported beam bridges in which the beam body is made of concrete prefabricated parts, and the construction of air-rail bridges in which both rail beams and piers are prefabricated steel structure parts. [0003] In order to meet the design and operation requirements, the bridge elevation and the axial coincidence of the adjacent two beams along the bridge direction are usually fine-tuned when the bridge is erected. Since the rail beams and bridge piers are all prefabricated steel structures, and there are pro...

AI Technical Summary

Problems solved by technology

Since the track girders and bridge piers are all prefabricated steel structures, and there are problems such as component deformation caused by transportation and hoisting, the actual installation positions of the bridge and bridge piers after fine adjustment are vertical, front-to-back horizontal, left-right horizontal and theoretical. The installation position produces a large misalignment error. The misalignment error will lead to the misalignment of the installation interface size between the bridge support and the bridge and pier, resulting in the failure of the support to be installed and unable to meet the design elevation and position requirements of the track beam.

Moreover, the installation misalignment error value of each bridge section and the corresponding pier is different, and the existing bridge support and concrete cast-in-place method cannot eliminate the installation error of the beam pier
