Embodiment Construction

[0055] The construction method of the present embodiment, concrete steps are as follows:

[0056]S1. Stand steel structure installation

[0057] According to the characteristics of the truss in this project, most of the truss structures need to be assembled on site, so they are manufactured in parts from the factory and transported to the construction site.

[0058] The assembly sequence should be ahead of the hoisting sequence, but attention should be paid to saving the number of tire frames used for assembly, and two factors should be considered comprehensively to maximize the savings in construction costs and shorten the construction period.

[0059] Installation process: work preparation → small assembly unit → medium assembly unit → assembly acceptance → delivery and hoisting → welding → post-repair rod installation.

[0060] S2. Profiled steel plate installation

[0061] 1) Installation sequence

[0062] When laying profiled steel plates in the same floor plane, it is...

Abstract

The space positioning and installation construction method of a large arc-shaped steel frame stand of the present invention comprises the following steps: s1. Installing the steel structure of the stand; s2. Installing a profiled steel plate; Steel frame; s5. Grandstand platform construction; s6. Seat positioning and tuyere opening; the spatial positioning and installation of the arc-shaped steel frame grandstand of the present invention, compared with the concrete grandstand, has faster construction speed, and this technology saves the construction period of the grandstand , creating a working surface for interspersing other follow-up processes; saving costs and having good economic and social benefits.

Description

technical field [0001] The invention relates to the construction field of steel frame stands, in particular to a method for spatial positioning and installation of a large arc-shaped steel frame stand. Background technique [0002] In recent years, with the continuous development of the economy, large domestic venues and theaters have been continuously upgraded and replaced, and most of them are steel structures. In order to meet the audience's vision and comfort, the stands are mostly arc-shaped stepped stands, and the height of each step is different. The accuracy of the construction and positioning of the stands is particularly important. [0003] In the "Zhongxian E-sports Stadium" project, the inclined platform of the indoor grandstand is a steel structure + concrete composite structure, and the arc-shaped stepped audience stand is a steel frame + concrete structure. There are more than 6,000 seats in the venue, the maximum arc radius of the platform is 41m, and there ...
