Abstract

The invention discloses a large-span steel structure net rack lifting construction method, and relates to the technical field of steel structure net rack construction. The large-span steel structure net rack lifting construction method comprises the following specific steps that firstly, a steel net rack is assembled on the ground; secondly, lifting equipment is installed; thirdly, the steel net rack is tried to be lifted; and fourthly, the steel net rack is lifted. The whole method is suitable for large-span steel structure net rack lifting construction in general industrial and civil buildings through design economical efficiency, and through design safety, the lifting stress conditions of a lifting support and the steel net rack are calculated and analyzed through finite element analysis software, it is determined that the structural design is reasonable, the specification of raw materials and the rated power type selection of a hydraulic lifter are large, the safety reserve is high, and the operability of the design is as follows, the net rack main body is assembled on the ground, so that safety, convenience and rapidness are realized; and the hydraulic synchronous lifting technology for the ultra-large component is mature, wide in application and high in safety coefficient.

Description

technical field [0001] The invention relates to the technical field of steel structure grid construction, in particular to a construction method for lifting a large-span steel structure grid. Background technique [0002] In recent years, in many engineering applications, the grid structure has replaced the reinforced concrete and has been widely used. The grid structure is a space structure composed of multiple rods connected by nodes according to a certain grid form. With the advantages of small force, light weight, high rigidity, and good seismic performance, it can be used as the roof of gymnasiums, theaters, exhibition halls, waiting halls, stadium stand awnings, hangars, two-way large column spacing workshops, etc. However, now Some network frame structures have defects in economy, safety and operability during the process of lifting construction. Contents of the invention [0003] The purpose of the present invention is to provide a large-span steel structure netwo...
