△ The Jiujiang Resettlement Housing Project of China Construction Science and Engineering Corporation at the observation site was the first batch of steel structure precast housing projects in Jiangxi Province, and also the first all steel structure precast housing project in Jiujiang City.

The internal partition wall system adopts ALC batten, which is light and high-strength, green and environment-friendly, convenient for construction, no wet operation, and free of plastering.

We will work with our peers in the industry to promote the low-carbon transformation of the construction industry and promote the industrialization, green and intelligent development of buildings.

With the close combination of intelligent, digital and precast buildings, the building industrialization process is expected to achieve accelerated and leapfrog development.

Through the flexible connection with the steel structure, it achieves a good coordinated deformation and sound insulation effect.

The foundation wall of the peripheral protection system uses ALC battens and integrated thermal insulation and decoration boards to build a triple waterproof structure, improve the impermeability, reduce the wall’s thermal conductivity, and create a quiet and comfortable living environment while ensuring the beauty of the building.

It is hoped that the project will strive to build a benchmark project of precast buildings in Lianxi District, form a batch of good practices and accelerate the development of precast buildings in Lianxi District.

As the first all steel structure precast residential project in Jiujiang City and the first batch of key steel structure precast residential projects in Jiangxi Province, since the commencement of the Jiujiang resettlement housing project, CSCEC and various units have worked together to complete various construction tasks with high quality.

Xiong Jingang analyzed the current situation and future development trend of China’s precast construction industry.

In 2019, the Ministry of Housing and Urban Rural Development approved Jiangxi and other seven provinces to carry out the pilot construction of steel structure precast housing.

The project uses BIM’s information sharing and cooperative office technology to carry out the whole process and all-round information integration from design, manufacturing, assembly, decoration to management.

With the help of this observation meeting, Jiangxi Construction Industry Association will summarize the advanced experience in project construction, further innovate the content, means and mechanism, and constantly create a new situation in the construction of precast buildings in Jiangxi Province.

CSCEC Jiujiang Resettlement Housing Project is the first all steel structure precast residential building project in Jiujiang City.

and co organized by the Housing and Urban Rural Development Bureau of Lianxi District, Jiujiang City, was held in the Jiujiang Resettlement Housing Project in Central China.

Zhang Hua pointed out that steel structure precast housing can effectively improve the construction quality and efficiency and meet the residential requirements of residents in the new era.

More than 150 people, including Li Lei, member of the Standing Committee and deputy head of Lianxi District Committee of Jiujiang City, Ye Qing, deputy director of Jiujiang Housing and Urban Rural Development Bureau, Zhang Hua, vice chairman of Jiangxi Construction Industry Association, Xiong Jingang, deputy director of Jiangxi Precast Building Expert Committee, leaders, enterprise representatives, experts and scholars of relevant government departments and construction industry associations in Jiangxi Province and Jiujiang City, and relevant personnel of CSCEC Central China and Wuhan Company, attended the meeting.

Assembled buildings have unique advantages in terms of cost and duration through efficient construction methods, At the same time, it is very consistent with the national environmental protection policy and the “double carbon” strategy.

The total construction area of the project is 344000 square meters, including 78500 square meters in the northern Luozishan plot, which is made up of six high-rise residential buildings and a 2-storey farmers’ market, with one underground floor and 26 floors above the ground.

CSCEC will actively practice the new development concept and continue to promote the innovation and practice of steel structure precast buildings.

Taking the Jiujiang Resettlement Housing Project of CSCEC as the carrier, the exhibition comprehensively demonstrated the latest achievements of Jiangxi Province in the design, construction technology and on-site industrialization of cast buildings.

He pointed out that China’s construction industry is currently on the path of industrialization transformation from a labor intensive to a new type of building with high technology content, good economic benefits, low resource consumption and less environmental pollution.

The floor slab adopts the bottom membrane detachable steel bar truss floor bearing plate.

The steel members are flexibly arranged along the direction of the building walls, to meet the layout requirements of residential buildings for ventilation and lighting, full exposed house type, and indoor streamline optimization, and to meet the performance conditions of large span, large space, house type variability, high occupancy rate, etc.

Adhering to the concept of housing construction in the new era, and on the premise of ensuring the quality of the project, it realizes the convenient decoration of industrialization, standardization, and data, and the convenient maintenance of components that can be replaced and used.

In the design stage, BIM visual simulation technology is used to promote the in-depth interaction of various disciplines, solve the pipeline collision problem, and realize the digital management and refined management of the project.

Welcome.

The project adopts a steel structure+shear wall enclosed residential system.

Li Lei pointed out in her speech that Lianxi District will vigorously promote the development of precast buildings by taking precast buildings as a strategic measure to realize the transformation and upgrading of the traditional construction industry.

Precast steel bar truss can reduce the on-site steel bar binding, the bottom membrane can be reused, increase the turnover times, and the formed surface is good after the removal of the formwork, meeting the requirements of the indoor beauty of the residence.

During the construction process, there is no need to set up full scaffolding, only a small amount of support is arranged to save the input of wood and traditional steel pipe frame.

The steel members are hidden in the main building walls, and there are no convex beams and convex columns indoors.

On October 25, the 2022 Jiangxi Steel Structure Assembled Residential Building Construction Site Observation Meeting, sponsored by Jiangxi Construction Industry Association, organized by CSCEC Group Co., Ltd.
