Unloading structure of steel truss support and construction method of track unloading using this structure

Abstract

The invention discloses a steel truss support unloading structure and an unloading method. The steel truss support unloading structure includes at least three steel trusses, connecting pipes symmetrically arranged in the middle of both sides of the steel trusses, and rails symmetrically arranged at the bottom of the steel connecting beams. The dismantling structure includes a steel column limb, a hemisphere arranged at the bottom of the steel column limb, a sliding shoe clamped on the track, a pressure plate for fixing the sliding shoe and the hemisphere, and support components symmetrically arranged on both sides of the steel column limb. The support assembly includes a pipe support, a jack and a jack base, the jack base is arranged on the track, the lower end of the connecting pipe is set on the pipe support, and the jack is arranged between the bottom of the pipe support and the jack base. The equipment has simple structure, convenient processing, flexible layout, reliable bearing capacity, safety and stability, and can meet the unloading requirements of all support points. At the same time, the tooling can completely remove the sliding track, so that the track can be used in different projects. It has high promotional value.

Description

technical field [0001] The invention relates to the technical field of steel structure horizontal sliding, in particular to a steel truss support unloading structure and an unloading method. Background technique [0002] Steel trusses refer to trusses made of steel, such as roof structure crane beams, bridges and hydraulic gates of industrial and civil buildings, etc. Steel trusses are commonly used as the main load-bearing components. Various towers, such as mast towers, TV towers and transmission line towers, are commonly used as space steel trusses composed of three-sided, four-sided or multi-sided planar trusses. Steel trusses are the main components of load-bearing structures. [0003] At this stage, after the unloading and construction of the steel truss support is completed, the main problems are: first, the sliding shoes and the track at the lower part of the steel truss cannot be completely recovered; The waste of resources is large and the cost is high.
