Problems solved by technology

[0003] For example: in the construction of the grand theater of the Guangxi Culture and Art Center construction project, during the construction of the stage roof, it is necessary to build a full house of scaffolding from the base floor surface -17.0m elevation, and the required support height for installation exceeds 50m, so a lot of supporting steel pipes are required. Not only waste materials, but also cumbersome construction, long construction period and high risk of safety management
[0004] In addition, in the construction of the traditional bottom-up grand theater, the top steel structure system has residual stress caused by deformation, and the process is complicated and the cycle is long

Embodiment 1

[0059] Embodiment 1: A method of reverse installation and construction of the steel structure of the indoor stage of a grand theater. The steel beams on the roof layer of the stage of the grand theater are reversely constructed and installed, and the support system is erected and installed from bottom to top, including the following steps:

[0060] (1) BIM simulation analysis

[0061] Carry out BIM modeling for the civil engineering and indoor steel structure of the grand theater, and simulate and stress analysis for the installation of steel beams on the stage roof and the erection support system for its construction;

[0062] After the simulation analysis, enter the construction stage. Before the construction, it must be ensured that the steel components have been submitted for inspection and passed, and the materials, components, and machinery required for construction have all entered the site;

[0063] (2) Measurement preparation

[0064] Construction survey to determine...

Abstract

The invention discloses an inverse installation and construction method of an indoor stage steel structure in a theater. The method includes the steps of BIM simulation analysis, measurement preparation, embedded part installation, erection of a supporting system, pre-assembling of steel girders and davits of a stage roof layer, steel girder installation of the stage roof layer, steel structure installation of a stage machine process, disassembling and dismantling of the erected supporting system and coating installation of the steel structures. According to the construction method, by adopting BIM modeling and conducting installation simulation and force analysis on the steel structures, a more scientific and economical technical scheme can be chosen, and the quality and safety problems likely to happen can be found and solved in advance, the construction quality is ensured, costs are reduced, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a reverse installation and construction method of the indoor stage steel structure of a grand theater. Background technique [0002] The interior of the existing grand theater is mostly a multi-storey super-high hanging steel structure, and its stage roof is composed of a combination of steel structure and concrete. In the construction of multi-storey ultra-high hanging steel structure, it has the characteristics of large span, high support height required for installation, lack of working surface during installation, complex three-dimensional intersection construction, and high installation accuracy requirements. [0003] For example: in the construction of the grand theater of the Guangxi Culture and Art Center construction project, during the construction of the stage roof, it is necessary to build a full house of scaffolding from the base floor surfa...
