Deviation integral elevation steel corridor carrying method and lateral limiting device thereof

Abstract

The invention relates to a deviation integral elevation steel corridor carrying method and a lateral limiting device thereof. According to the method, an upper chord of the outer sides of lifting lugs of the two ends of an existing steel corridor is closely provided with the lateral limiting device which is composed of a force transmitting steel beam and front and rear support rods on the front and rear side surfaces of the steel beam and has front and rear as well as left and right limiting functions and a function of supporting the steel corridor to deflect from below an orthographic projection of the set position of the steel corridor, so that steel corridors can be combined and assembled on the ground on the limiting position of the lateral limiting device, a hanging mechanism can hoist in a low level slant manner, barriers below the orthographic projections of the set positions of the steel corridors are avoided, and the corridors can integrally perpendicularly rise in a deviation manner. The deviation integral elevation steel corridor carrying method and the lateral limiting device thereof provided by the invention have the advantages that the problem that normal construction is influenced by building barriers below the orthographic projections of the set positions of the steel corridors is solved, the high altitude operation capacity and the transport capacity of dispersing materials are reduced, the construction is convenient, the operational efficiency is high, the construction cost is low, the construction quality is guaranteed, and the production is safe. The deviation integral elevation steel corridor carrying method is an innovation of the construction process for vertically lifting a steel structure piece in a wide span and has high practicability and operability.

Description

technical field [0001] The invention relates to the technical field of installation and construction of building steel structures, in particular to a method for offset overall lifting of steel corridors into place and its lateral limit, which is suitable for the interconnection and erection of high-altitude large-span steel corridors between high-rise buildings device. Background technique [0002] In the construction of urban beautification and construction, various novel buildings with different styles emerge in endlessly. In the construction of some specially designed construction projects, some new issues that have not been encountered in the prior art are often encountered. For example, for a project that needs to be interconnected between the near top floors of high-rise towers, a number of steel trusses and In the construction of steel corridors composed of steel frames, at present, it is generally used to build support frames upward on the ground below the orthograp...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that in some construction situations in the prior art, it is impossible to build a support frame on the ground below the orthographic projection of the steel corridor setting position due to obstacles on the ground below the orthographic projection of the steel corridor setting position or between the intermediate floors. Or assembled tire frames, which affect the construction of high-altitude construction platforms or the inadequacies of assembling steel corridors on the ground under the orthographic projection of steel corridors and vertically lifting them into place, providing a way to avoid steel corridors. Orthographically project the obstacles between the ground floors below, and ensure that the steel corridors are assembled on the ground to build tire frames, and the combined and assembled steel corridors are lifted to a high altitude as a whole, and the offset positions of the butt joints are overall lifted.
