Abstract

The invention discloses a construction method of a large-span hangar. The construction method comprises the steps that a plurality of steel structure units are spliced into a steel structure integral lifting unit, and a lifting platform is arranged; a hydraulic synchronous lifting system is installed and debugged; the steel structure integral lifting unit is lifted to a first height to suspend lifting, and continues to be lifted to a second height to suspend lifting so as to install a gate truss and a net rack butt joint rod; the steel structure integral lifting unit is lifted to a third height which is a preset distance away from the installation elevation to suspend lifting; the lifting speed of the steel structure integral lifting unit is reduced, and all lifting points are finely adjusted, so that the steel structure integral lifting unit reaches the design position; and rod pieces are additionally installed between the steel structure integral lifting unit and a steel structure supporting frame and between the steel structure integral lifting unit and another steel structure integral lifting unit. According to the construction method of the large-span hangar, the technical problems that in an existing hangar construction method, the construction difficulty is large, and control over the safety, quality and construction period of steel structure field installation is not facilitated can be solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for a large-span hangar. Background technique [0002] In modern buildings, more and more grid structure roofs are used. It has the characteristics of light structure, high strength and low cost. It is currently the most popular and fastest-growing structural form, and is widely used in large and medium-span systems. . With the application of large steel structures in engineering, reasonable consideration of the lifting of large components has become an important technical link in the construction of steel structures. Combined with the practical situation, there are relatively large advantages in adopting the synchronous lifting method for the steel structure grid. [0003] However, the steel lattice column double-span hangar grid composite components, connection node structure and stress are very complicated, and the welding process and i...
