Strengthen policy guidance, develop standardized design guidelines for precast buildings, develop selection guidelines for recommended component sizes, interfaces, etc., and guide the standardization of components; Periodically release the information of components through the official website or information platform to guide the selection of design and construction units.

The construction period is short, and the plant area reaches 200000 square meters.

According to the Standard System of Fabricated Buildings in Sichuan Province, which is being prepared by our institute, the current precast building standards are basically based on structure, with a small number of structural standards for enclosure system.

The structural design of Tencent Chengdu A and B Block Construction Engineering Design Project won the first prize in the engineering survey and design industry; Tencent Chengdu A and B Block Building Engineering Design Project, Innovation Incubation Base (Industrial Headquarters Base) Phase I Project R&D Exhibition Center, Sichuan Provincial Standard for the Definition of High-rise Civil Building Engineering with Seismic Fortification Exceeding the Limits, and Sichuan Provincial Atlas of Additional Structure of Existing Residential Elevators won the first prize of Sichuan Province; The trial court of Sichuan Provincial Higher People’s Court, Xincheng Middle School, Huayannian • Xiangnian Square, and Huayannian • Funian Square won the second prize of Sichuan Provincial Excellent Award.

Q: In the new situation of construction industrialization, the concept of “standardization” is reflected in all aspects of the precast construction industry.

This is also the main reason for the high cost of precast components and the difficulty in controlling the construction technology.

The technical systems of European, Japanese and other countries introduced from different regions are different, the leading structure is different, and the technology gap is large.

1 project supervised by Yibin Municipal Government in 2020.

It is generally reflected in the industry that the standardization of component design and production scale cannot be realized, mainly because of the lack of positive design and reasonable planning in the early stage, resulting in a large number of special-shaped components in precast construction projects, a large number of mold types, and various construction projects are not common, and the waste is serious; The production efficiency of the components is low, which affects the large-scale production and the production capacity.

In order to accelerate the construction of precast building standardization and promote the transformation and upgrading of building industrialization, digitalization and intellectualization, the Sichuan Provincial Department of Housing and Urban-Rural Development, the Sichuan Provincial Department of Economy and Information Technology, the Sichuan Provincial Department of Science and Technology, and the Sichuan Provincial Bureau of Market Supervision and Administration jointly formulated and issued the Work Plan for Promoting the Standardization Construction of Precast Building in the Province in June 2022.

Personal Profile of Tang Yuanxu, Chief Engineer (Structure) of Sichuan Provincial Institute of Architectural Design and Research Co., Ltd.

The project was started in January, the most serious epidemic in 2020, and was completed and put into use within one and a half years..

At present, our institute is assisting the Chengdu Municipal Bureau of Housing and Urban-Rural Development to set up a project called “Part Design Guide”, which is also the focus of next year’s work.

On the basis of the standardization of the size and interface of the parts and components, the structural design integrates the standardization of the parts and components into the design scheme of all projects according to the logic of the parts and components assembly, which can realize the design and production organization of the parts and components in advance, separate from the promotion process of the specific project, and shorten the construction period.

Standing at the height of the precast building structure design industry, the Association’s Propaganda Department provided reflections on the above issues from the perspective of industry status, technical innovation, application transformation and other aspects.

As the person in charge of the structure discipline, I adopted the cast steel structure scheme after the comparison and analysis of multiple schemes.

Q: As the chief structural engineer of Sichuan Architectural Design and Research Institute Co., Ltd., what excellent projects and successful cases do you want to share? How did these projects achieve the standardization of precast buildings? A: Yibin Jimi Intelligent Optoelectronic Industrial Park is the project that Premier Li Keqiang pays attention to, and is also the No.

In addition, in order to strengthen the technical exchange and sharing within the industry, the Design Special Committee will hold technical exchange activities for member units every year to exchange and learn about the cutting-edge technology and technology of precast buildings and successful design experience.

From the perspective of the formulation and implementation of precast building standards in the province, what work do you think is urgently needed? A: At present, it is urgent to improve and unify the local standards for the whole process of precast buildings in Sichuan Province.

Component standardization is the basis for the development of component parts, which needs to be improved urgently.

The early development of precast buildings mainly focuses on the prefabrication of structural systems, and the supporting facilities such as enclosure system, decoration, equipment pipeline, integrated kitchen and bathroom are insufficient, resulting in incomplete industrial system and overcapacity of structural components in some areas.

Q: As an expert in the field of structural design, how do you think practitioners in this field should change their thinking and jointly promote the standardization of precast building components? A: Structural design should change the design thinking and design methods, actively improve the design process and information tools, and improve the design efficiency, so as to promote the informatization and intelligence of the whole building construction process.

Q: As the director of the Design Committee of Sichuan Assembled Construction Industry Association, from the perspective of industry development, what hot and difficult issues do you focus on in the industry? What are your corresponding work plans? A: As the director of the design committee of the Association, I pay more attention to the standardization of components and design standardization.

After the policy was issued, the industry came to the crossroads of standardization transformation: why is it urgent to promote standardization in an all-round way since the development of precast construction industry? How will the standardization requirements for component products and construction technology affect the market and even the industrial development direction? How can relevant enterprises seize the development opportunity to win the future? In order to explore relevant issues, the Association’s Propaganda Department interviewed Tang Yuanxu, the chief structural engineer of Sichuan Institute of Architectural Design and Research Co., Ltd., and the director of the Design Committee of Sichuan Precast Building Industry Association.

There is only one standard for precast decoration, and there is no current local standard for equipment pipeline, integrated kitchen and bathroom.

In 2022, the Department of Housing and Urban-Rural Development and other departments issued the Work Plan for Promoting the Standardized Construction of Precast Buildings in the Province, which clearly proposed to improve the standard system for the design, production, construction, decoration and acceptance of precast buildings.
