Stadium net rack construction method

Abstract

The invention discloses a stadium net rack construction method. A net rack is spliced and fully paved on the plane of a middle sunken field of a stadium; a jacking frame is arranged below the lower chord ball of the net rack; the jacking frame jacks the net rack, the jacking frame stops when the bottom of the net rack exceeds the stadium stand and meets the splicing height of the next net rack, the net rack continues to be spliced on the stand, and the jacking frame is arranged below the newly-spliced net rack; the process is repeated until the net rack covers the whole stand; and the jacking frame falls down, and net rack construction is completed. The purpose of step-by-step and block-by-block construction is achieved by jacking the net rack while installing the net rack and relying on the stadium stand as a construction platform, constructors can walk upwards on the stand step by step and continue to construct along with rising of the net rack, then the whole stand is covered by the net rack, and the problems that the site is limited, construction efficiency is high, and construction cost is low are solved. And when the net rack needs to be assembled subsequently, a large number of scaffolds are erected, so that the construction progress is slow, and the construction cost is high.

Description

technical field [0001] The invention relates to the technical field of steel structure construction, in particular to a construction method of a stadium net frame. Background technique [0002] The steel structure grid is a space structure formed by connecting multiple rods through nodes according to a certain space grid form. It is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation, so it is especially suitable for building large-span, ultra-high, and ultra-heavy buildings; the material has good homogeneity and isotropy, and it is an ideal elastic body. , which is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well; the construction period is short; its high degree of industrialization can carry out specialized production with a high degree of mechanization, steel The structure should s...

Problems solved by technology

[0003] There are many installation methods for steel structure grids, generally high-altitude bulk installation, block installation method, high-altitude sliding method, overall hoisting method, etc., but the above-mentioned high-altitude assembly methods have the following disadvantages: because the assembly method of high-altitude grid structures requires scaffolding , and the workload of scaffolding construction is huge, and the amount of turnover materials is large, the time span is long, the construction cost of renting scaffolding is high, it is difficult to guarantee the completion of the project on schedule, and then affects the delivery of the entire project on schedule; such as the steel structure with the publication number CN 105178609 A Both the high-altitude bulk construction method of the grid and the two-way rotation and lifting construction method of the space grid steel structure with the publication number CN110065887A all use a large number of scaffolds to carry out the follow-up construction of the suspended grid, which has a large workload and affects the construction progress
