has always been committed to technological innovation in precast construction, and has obtained a number of independent innovation achievements, making China’s precast construction reach the international leading level and leading the direction of future urban construction development.

It not only saved the amount of woodwork, but also greatly improved the work efficiency.

In the main construction project of Zhonghai Jingsan Institute, the second bid section consists of 11 main buildings, all of which are assembled with integral shear wall structures.

The construction process is like “building blocks”.

When the houses are assembled, 60% of the prefabrication rate and 50% of the overall assembly rate can be achieved.

There are 6 types of “small building blocks” PC components, with a total number of more than 15000 pieces.

Compared with traditional building methods, the construction technology of precast buildings has certain technical difficulties, but also has absolute advantages.

China Construction Second Engineering Group Co., Ltd.

Inherit the spirit of ingenuity, focus on the quality of the project, China Construction Second Engineering Bureau uses green intelligent manufacturing to build the city dream, promote the transformation and upgrading of the construction industry, continue to move forward, Nanjing Dingjiazhuang Phase II affordable housing project, Nanjing Thomas Experimental School Greenland Qingyang Caiqiao project, plot 1 # 2 # Shenzhen Tianji Mansion Project of Jiashan Peacock City · Yuelongwan (Phase 1) Project of Plot 4 # Jinmaoyue Project in Weishanzhuang Town, Daxing District, Beijing Zhuoda perfume Sea Phase IV Qiaojun Project.

Fabricated buildings are processed and cast in the factory, and then transported to the construction site for assembly.

The project faces the challenge directly to ensure accurate assembly.

In the early stage of construction, the Project Department used BIM modeling technology to optimize the construction of cast components.

Under the construction scheme of high assembly rate, the project of Zhonghai Jingsanyuan, with a total construction area of 131100 square meters, can be described as a “building block kingdom”.

In March 2022, the Ministry of Housing and Urban Rural Development of the People’s Republic of China issued the “Fourteenth Five Year Plan” for Building Energy Efficiency and Green Building Development, which proposed that by 2025, the proportion of precast buildings in the total number of newly built urban buildings in China would reach 30% today, CCTV2 reported the highlights of the precast construction process of China Construction Second Engineering Bureau under the title of “Green Building Planning Release, Promotion and Acceleration of Fabricated Buildings”, which comprehensively demonstrated the construction advantages of precast buildings and the development trend of the industry.

In the interview, Mr.

Their income can be increased by more than 10% compared with the previous traditional construction methods.

Jia, who has been engaged in the construction industry for 16 years, said that he began to engage in assembly construction six years ago.

The interior walls at the beginning of the fifth floor are precast walls, and the stairs above the ground are precast and installed.

The project manager said that compared with the traditional construction method, the construction period of precast buildings can be shortened by more than two months, and the cost can be reduced by 3% – 5%, and the quality is more guaranteed because the main components are processed in the factory.

Before construction, it carried out fine simulation for each process and each step of the standard floor hoisting, found out the possible dynamic interference and optimized it, reduced the risk level of hoisting work, ensured that the on-site component size was accurate, and the hoisting process was scientific and orderly.

This construction method not only significantly improved the working environment, but also reduced the intensity of work.

China Construction Second Engineering Bureau has successively undertaken the construction of many well-known PC buildings at home and abroad, such as the largest precast public housing project in China – Shenzhen Changzhen Public Housing, and the largest precast comprehensive pipe gallery project in China – Mianyang Pipe Gallery PPP Project, and has accumulated rich experience in assembly construction.

The floor slabs above the ground are precast composite slabs.
