Standardize the special design documents of precast buildings.

For the evaluation standard of precast buildings (GB / t51129-2017) and The evaluation and scoring points of interior decoration in the detailed rules for calculation of assembly rate of precast buildings in Sichuan Province are described in detail, so as to provide reference for interior decoration evaluation in the calculation of assembly rate of precast buildings in our city-.

The provisions related to structural safety, public interest and public safety in the relevant national and Sichuan technical standards for precast buildings since 2017 are taken as the technical review contents of construction drawing design documents to ensure the design quality and structural safety of precast buildings.

In view of the problems such as inconsistent elements and lack of data in the design of precast buildings, clarify the preparation requirements of the design documents of precast buildings, formulate the special articles of precast building design and the template of documents submitted for approval, and further standardize the document elements.

The guidelines for the design of precast buildings in Chengdu and key points for the review of construction drawings (version 2021) are published in It is revised on the basis of the key points of construction drawing review of precast concrete building engineering in Chengdu.

3.

The revised content has the following characteristics: 1.

2 provide reference for interior decoration evaluation of assembly rate calculation.

It is divided into “guidelines for precast building design”, “key points of construction drawing design review of precast building” and “annexes”.

5), and the calculation of assembly rate shall comply with the national evaluation standard for precast buildings (GB / t51129) and the detailed rules for calculation of assembly rate of precast buildings in Sichuan Province Relevant regulations.

It is an important technical support and basis for the city to carry out precast building design and special review.

Recently, Chengdu Municipal Bureau of housing and urban rural development issued the guidelines for the design of precast buildings and key points for the review of construction drawings in Chengdu (version 2021) and the guidelines for the design and review of precast interior decoration of buildings for citizens in Chengdu, both of which will be implemented from March 1, 2022.

The detailed cast interior decoration design is based on the technical standard for cast interior decoration (JGJ / t491-2021), technical standard for precast Decoration Engineering of concrete residential buildings in Sichuan Province (dbj51 / t135-2020) and other technical standards comprehensively and systematically standardize the design requirements of precast interior decoration to further improve the design quality.

2 improve the design quality of precast buildings, add the content of design guidelines for precast buildings, clarify the design process and relevant requirements, and further standardize the design of precast buildings.

The guidelines for design and review of precast interior decoration of buildings for citizens in Chengdu are prepared in combination with the development needs of precast interior decoration in our city, which are divided into general principles, terminology, basic regulations, standardization, modularization, integrated design Fabricated floor (ground), cast partition wall, cast wall, cast ceiling, integrated kitchen, integrated toilet, equipment and electromechanical pipelines, other decoration parts and detail design, BIM application, cast interior decoration design and review points.

It mainly has the following two characteristics: 1.

Flat Steel Anchor

Adjust the calculation method of assembly rate, implement the requirements of the notice of Chengdu Municipal Bureau of housing and urban rural development on further improving the assembly requirements of construction projects in Chengdu (csjg [2021] No.
