General sliding support for land bridge construction

Abstract

The invention discloses a universal sliding support for land bridge construction, and relates to the technical field of bridge construction, and the universal sliding support comprises two bearing beams which are arranged in the transverse bridge direction in the length direction and are spaced from each other, and the bearing beams are fixed to the ground; the steel pipe supporting device comprises a plurality of steel pipe piles, the bottoms of all the steel pipe piles are movably assembled on the two bearing beams, and height-adjustable movable heads are arranged at the tops of the steel pipe piles; the supporting platform is used for supporting the box girder and is arranged on the tops of the more than four movable heads in a spanning manner; the position adjusting devices can slide in the longitudinal bridge direction relative to the supporting platform, each position adjusting device comprises a vertical jack and a transverse jack, and the vertical jacks are vertically arranged on the top face of the supporting platform and support the box girder; the transverse jack is horizontally arranged on the top face of the supporting platform and used for changing the position of the vertical jack in the transverse bridge direction. The universal sliding support can be integrally and repeatedly used, and the vertical position, the transverse position and the longitudinal position of the box girder can be conveniently and rapidly adjusted.

Description

technical field [0001] The present application relates to the technical field of bridge construction, and in particular to a sliding universal support for land bridge construction. Background technique [0002] At present, the transportation industry, as the "artery" and "pioneer" of the national economy, is also developing rapidly. The number of bridges spanning various terrain conditions is gradually increasing, and the field of bridge construction is facing more and more technical challenges. In bridge construction, the construction of the superstructure of the bridge (referring to the structure above the pier) is a particularly important part. For the construction of land bridges, the superstructure is mostly supported by bracket construction, and the most widely used ones are full-house brackets and pipe pile brackets. . [0003] Among them, the full house support method is greatly affected by the height restriction. When the height exceeds a certain range, the full ho...

Problems solved by technology

[0004] However, due to the influence of the height of the bridge and its own structure, the full hall support method and the pipe pile support method lead to the installation and removal of supports only following the construction principles of "integration from zero" and "integration from zero", and a lot of manual work is required in the process , Long-term mechanical assistance, which reduces work efficiency and increases construction costs

At the same time, the full hall support method and the pipe pile support method are very inconvenient for the fine position adjustment of the bridge beam body during the construction process, and the bridge line shape is not easy to control

[0005] Therefore, those skilled in the art urgently need to design a technical problem that can solve the large amount of work for disassembling and assembling the bracket and the inconvenient adjustment of the fine position of the beam body.
