The Ministry of housing and urban rural development of Chongqing recently issued the technical guide for building precast steel structure
Technical guide for modular construction of cast steel structures June 2022 acquisition method 1 Follow wechat official account “specification Atlas.
It is estimated that the main assembly rate of modular buildings can reach more than 90%, the on-site labor volume can be reduced by 70% compared with the traditional mode, and the comprehensive construction period can be shortened by more than 1/3 compared with the traditional construction mode.
While realizing standardized production and rapid integrated assembly, it ensures the high quality of the project and the green and low-carbon development of the project construction.
According to the news on the website of the Ministry of housing and urban rural development on June 13, in order to promote the development of precast steel structure module building, the Ministry of housing and urban rural development organized the preparation and recently issued the technical guide for precast steel structure module building.
Modular building is a new model for the development of precast buildings, which conforms to the development direction of building industrialization, intellectualization and greening proposed in the guiding opinions on promoting the coordinated development of intelligent construction and building industrialization and several opinions on accelerating the development of new building industrialization formulated by the Ministry of housing and urban rural development and other departments.
Modular architecture modularizes the building space in the design stage, and carries out architectural integration and integrated design, which not only ensures the expandability of functional space, but also ensures the maximization of component repetition rate; In the production stage, the modular units can realize factory standardized assembly line mass production, and the uniformity of building quality can be well guaranteed; In the construction and installation stage, the overall module unit assembly and installation method is adopted, which has higher installation accuracy and faster assembly speed, and is conducive to the realization of digital information coordination, tracking and management in the whole process of design, production and construction.
Fabricated steel structure module building (hereinafter referred to as “module building”) is a cast building mainly composed of steel structure integrated module units on the construction site.
Among them, the steel structure integrated module unit (hereinafter referred to as “module unit”) is a three-dimensional space body with building use function, which is composed of factory precast steel structure main structure, enclosure wall, bottom plate, top plate, interior parts, equipment pipelines, etc.
The modular building factory has a high degree of completion and integration.
In terms of green and low-carbon, compared with the traditional construction method, the modular building can reduce the on-site construction waste by more than 75% and the on-site construction noise pollution by more than 90%.
It is suitable for apartments, hotels, schools, dormitories, residences, medical treatment, office and other civil buildings, as well as some industrial buildings.
This guide is applicable to the design, fabrication, installation, quality acceptance and maintenance management of industrial and civil modular buildings.
It has the advantages of fast construction, good construction and complete functions.
