Problems solved by technology

The traditional construction method of the return air channel of the steel structure is to gradually form the whole return air channel after the high-altitude in-situ splicing and welding of the steel components. This construction technology has many high-altitude installations by workers, difficult control of the assembly accuracy of the high-altitude steel components, and long assembly time. disadvantages

Abstract

The invention discloses a construction method for whole-roof-truss of air return narrow lane steel structures. The construction method includes the following steps that steel column bases are mountedon fixing supports; steel members are spliced and welded on the ground to form whole-roof-truss steel structures; after the whole-roof-truss steel structures are welded, the whole-roof-truss steel structures are hoisted in place, and the whole-roof-truss steel structures are subjected to direction control in the hoisting process; the whole-roof-truss steel members are temporarily fixed after beinghoisted in place, position correction is carried out, after position correction is carried out, all the whole-roof-truss steel members are temporarily fixed with the method, and every two adjacent whole-roof-truss steel members are connected. By means of the construction method for whole-roof-truss hoisting of the air return narrow lane steel structures, the amount of aloft work is reduced, meanwhile, the working efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for hoisting a whole steel structure with a return air channel. Background technique [0002] In recent years, steel structures have been widely used in factory buildings. The return air ducts of large electronic workshops are usually in the form of steel structures, that is, the return air ducts are equipped with steel columns and steel supports between columns. The traditional construction method of the return air channel of the steel structure is to gradually form the whole return air channel after the high-altitude in-situ splicing and welding of the steel components. This construction technology has many high-altitude installations by workers, difficult control of the assembly accuracy of the high-altitude steel components, and long assembly time. disadvantages. Contents of the invention [0003] The main purpose of the present inventio...
