It provides a demonstration for China’s cast steel structure building technology system and has strong popularization and application value.

Environmental benefit analysis of technology all components of precast buildings are precast in the factory and assembled on site, which realizes the lightweight of construction waste on the construction site, reduces wet operation, reduces the noise on the construction site, and has obvious environmental benefits.

Main technical performance and indexes the technical system provides a system solution to meet the building functions in the main body of precast building steel structure, floor slab, internal and external wall panels, and meets the evaluation index requirements of the national standard evaluation standard for precast buildings (GB / t51129-2017).

It is conducive to the development of building industrialization in China, improve production efficiency, save energy, develop green buildings, and improve and ensure the quality of construction projects.

Moreover, the cast structure can continuously complete multiple or all processes of the project in sequence, so as to reduce the type and quantity of construction machinery entering the site, eliminate the idle time of process connection, realize three-dimensional cross operation and reduce construction personnel, so as to improve work efficiency, reduce material consumption, reduce environmental pollution and provide guarantee for green construction.

It provides a demonstration for China’s precast steel structure construction technology system and has strong popularization and application value.

It is characterized by standardized design, factory production, assembly construction, integrated decoration and information management.

Application of technology in the market the “kumak building” project built with cast steel structure light plate building system was rated as the first batch of cast building demonstration projects and excellent observation projects of cast buildings in Guangdong Province by the Department of housing and urban rural development of Guangdong Province, and was recognized as the first cast steel structure building by Shenzhen housing and urban rural development system, At the same time, it has also won many honors, such as the 2017 Guangdong steel structure Gold Award “Guangdong steel Award”, Guangdong safe and civilized double excellent construction site, Shenzhen safe and civilized double excellent construction site, Shenzhen excellent structural engineering award, Shenzhen green building design gold certification, Shenzhen safe production demonstration site, Shenzhen green construction demonstration project, etc.

At present, the promotion of precast green buildings has shown a general trend, and various policies to encourage the promotion of precast buildings have been issued frequently all over the country.

Precast construction can better meet the requirements of land saving, energy saving, material saving, water saving and environmental protection of green construction, reduce the negative impact on the environment, including reducing noise, preventing dust, reducing environmental pollution, clean transportation, reducing site interference, saving water, electricity, materials and other resources and energy, and follow the principle of sustainable development.

On November 14, 2015, the Ministry of housing and urban rural development issued the outline for the modernization of the construction industry.

The Ministry of housing and urban rural development of China approved the evaluation standard for precast buildings as the national standard in December 2017, with the number of GB / t51129-2017, which will be implemented from February 1, 2018.

Compared with the traditional construction technology, it has obvious advantages in water saving, energy saving, material saving, land saving and environmental protection.

Precast structure can reduce construction waste to a large extent (about 30% – 40% of the total amount of urban waste), such as waste reinforcement, waste iron wire, waste bamboo wood and waste concrete.

With the rapid development of green building industry, precast steel structure buildings bloom all the time and quietly enter people’s daily life.

The precast building plan has been intensively issued since 2015.

And won the second prize of 2021 science and technology award of China Building Metal Structure Association.

The complete system of precast steel structure light plate building draws lessons from and absorbs the advanced technical achievements at home and abroad, combined with the promotion practice of domestic steel structure, continuously optimizes the design and improves the construction technology, which reflects the technical advantages of precast steel structure building.

Economic benefit analysis of Technology: the precast building is installed quickly, eliminating the formwork, scaffold and construction water land used in traditional building construction.

It integrates various business fields such as R & D design, production manufacturing and on-site assembly to realize energy conservation, environmental protection and It is a new type of building production mode with sustainable development to maximize the whole cycle value.

It is one of the good ways to improve construction quality and environmental protection.

The overall system has reached the domestic leading level and reached the international advanced level in the design and application of light wallboard.

What is a precast building? The precast building is based on the mode of component factory prefabrication production and on-site assembly installation.

The system is also applied to the EBC cast steel structure high-rise residential project of Nanyun home, Guangzhou, Thailand, the EPC cast steel structure high-rise residential project of Xiyue house, Dongtai, the “double eleven process” EPC cast steel structure school project of the third high-tech prefabrication school in Shenzhen, the EPC cast project of the fourth people’s Hospital of Longgang District, the exhibition center project of Guangming Science City, etc.

Today, let’s introduce the precast construction technology.

It is planned that precast buildings will account for more than 20% of new buildings by 2020 and more than 50% of new buildings by 2025.

With the application of cast steel structure light plate building system, all building components such as columns, beams, stairs, floors and wallboards are cast in the factory and can be completed only by assembly on site, which greatly reduces the number of construction workers on site, reduces the types of work accordingly and saves labor costs..

Encourage the development path of precast buildings to be gradually clear, and continuously improve the quality assurance standard of precast buildings.

Precast building is one of the important directions of building structure development in China.

Promotion prospect of technology the practice of the system meets the requirements of “four sections and one environmental protection” of cast steel structure building to improve quality, save construction period and reduce cost.
