Accumulation slippage construction device in icesword manner and construction method thereof

Abstract

The invention relates to an accumulation slippage construction device in an icesword manner and a construction method thereof. The accumulation slippage construction device comprises gliders at the lower part of a steel truss and a slide rail fixed above a steel truss support, wherein the gliders are icesword-type gliders distributed at the lower part of the steel truss at intervals along the direction of the slide rail; each section of icesword-type glider is two plain round bars parallel to the slide rail; the top of the plain round bar is welded together with the bottom of the steel truss; the bottom of the plain round bar is linearly contacted with the upper surface of the slide rail; and the bottoms of the steel truss closed to the slide rail are respectively connected with limit baffle plates. Using slippage contacting plain round bars with profile steel flat rails to replace slippage contacting flat gliders with train steel rails, the invention is economical, convenient, practical and effective, is applicable to places where cranes can not enter into the construction area in the presence of basement or other structures, as well as steel structures of small and intermediate spans where pushing jacks and train steel rails are difficult to purchase or the construction is not economical, and has great influence on the construction period by other construction methods.

Description

technical field [0001] The invention relates to a sliding construction device for high-altitude installation of a steel structure and a construction method thereof. Background technique [0002] Cumulative sliding is a steel structure installation method, which is suitable for the high-altitude installation of steel trusses. The principle is to divide the truss into several units, assemble a unit first, and then slide the unit out of the assembly site by pushing or pulling , continue to assemble on the site, and slide again after the assembly is completed. After several cycles of "assembly and slide", when all the trusses are assembled, they all reach the design position. The key to the accumulative slip method lies in the production of the slideway of the shoe. At present, there are two commonly used slideways for the shoe. One is a polytetrafluoroethylene (or polyvinyl chloride) slider with a flat slideway, and the other is a steel slide with a slide. "Ji" type train trac...

Problems solved by technology

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a cumulative sliding construction device and its construction method by the ice-skate method, to solve the problem that the traditional polytetrafluoroethylene slider is expensive, the rigidity of the polyvinyl chloride slider is low, and the rails of the train cannot be flexibly The technical problems of cutting; and solve the technical problems of uneven force and poor cumulative sliding effect when the truss slips
