1.0.5 The selection of precast building technical system shall comply with the provisions of the current national, industrial and Chongqing standards in addition to this guide.

2.0.6 Other types of particularly irregular public buildings, in addition to large-space public buildings, belong to the “particularly irregular” public buildings in the Code for Seismic Design of Buildings GB50011-2010 (2016 edition) (Article 3.4.1 of the Code and its interpretation).

Interpretation of terms; 3.

Each system sub-item can also select the appropriate technology or the encouraged technology according to the actual situation, but it should meet the key points of technical selection and relevant requirements.

2.0.5 The large-space public building mainly refers to the type of public building that is composed of one or more indoor large spaces (spanning multiple floors and multiple spans), most of which are not obvious and need to be analyzed and designed by using spatial structure model, and belongs to the “other high-rise buildings beyond the limit” specified in the Technical Key Points for Special Review of Seismic Fortification of High-rise Building Engineering.

and other units to conduct in-depth research and systematic analysis on the existing precast building technology system in the country, and based on the principle of “improving quality, improving efficiency, reducing labor and reducing waste”, combined with the city’s regional architectural characteristics, design and construction implementation capacity and key industrial foundation, Propose the appropriate precast building technology system and selection points for different building types, and formulate this guide on the basis of extensive consultation.

2.

When formulating the precast building technical scheme, it is appropriate to select the appropriate technical system or the encouraged technical system according to the four major systems.

General; 2.

1.0.3 The technical system selection table of this guide is prepared according to the building classification.

2.0.4 Special public buildings: public buildings other than general public buildings.

Explanation of terms 2.0.1 Suitable technical system is the main technical system of precast buildings with reliable technology, economic applicability, complete industrial supporting facilities and can be widely adopted at the present stage.

Industrial buildings; 7.

Such as large theaters, large stadiums, large terminals, etc.

Residential buildings; 4.

It mainly includes two categories: one is public buildings of large space type, and the other is other types of particularly irregular public buildings.

This guide is managed by the Chongqing Municipal Commission of Housing and Urban-Rural Development, and explained by the Chongqing Municipal Center for Housing and Urban-Rural Development Technology.

The introduction of Chongqing Municipal Commission of Housing and Urban-Rural Development in January 2023 is to further implement the Guiding Opinions on Vigorously Developing Precast Buildings (GBF [2016] No.

Special public buildings; 6.

Such as particularly irregular large shopping malls, large complexes and other public buildings.

2.0.2 Encourage the precast building technology system with high assembly level or technology integration and in line with the industrial development direction, but less applied in the project at this stage.

This guide is mainly used to guide the relevant practitioners of construction, design, consulting and other units to reasonably select the precast building technical system in the design of precast buildings.

The main contents of this guide include: 1.

2.0.3 General public buildings mainly refer to more regular public buildings of commercial, office, hotel, hospital, school, apartment, dormitory and other types.

Rural housing; And relevant appendices.
