Problems solved by technology
[0004] In order to overcome the deficiencies in the prior art, the present invention provides a cumulative sliding construction device and its construction method by the ice blade method, which solves the problems of high price of traditional polytetrafluoroethylene sliders, low rigidity of polyvinyl chloride sliders, and inflexibility of train rails. The technical problems of cutting; and solve the technical problems of uneven force and poor cumulative sliding effect when the truss slips

Embodiment
[0031] Example: The roofs of the north and south sides of the perennial exhibition hall of a museum are square steel pipe truss structures with an elevation of 34 meters. The span of the main truss is 21m, and the span of the secondary truss is 6m. It is 3.25 meters long, weighs more than 50 tons, and the site is narrow and changeable, and the construction period is very tight. Therefore, according to the characteristics of the project, it is decided to build a high-altitude platform at the design height of the truss to carry out cumulative sliding construction, and adopt the present invention, and carry out traction on the truss. slip.
[0032] see figure 1 As shown, the accumulative sliding construction device of the ice knife method includes the sliding shoe 4 at the lower part of the steel truss 3 and the flat slideway 2 fixed on the truss support 6, and the truss support 6 is fixedly connected to the pillar 1, The skates 4 are skate-type skates distributed at intervals a...

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 "assembly-slip" cycles, 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 kinds of slideways commonly used 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 tra...
