Strengthen "Sichuan Construction"! Sichuan Province continues to promote the application of prefabricated buildings

In recent years, Sichuan Province has ranked in the forefront of the western region in promoting the implementation of prefabricated building projects and industrial cultivation. Recently, data released by the Provincial Department of Housing and Urban-Rural Development shows that the province will start construction of 58 million square meters of prefabricated buildings throughout the year, and the industrial scale is expected to exceed one trillion.

In recent days, the exhibition halls of the Chengdu Museum of Natural History have completed the installation of exhibitions one after another, officially entering the sprint stage before opening. As the first irregular-shaped public building in Chengdu, the main pavilion of the Chengdu Natural History Museum is composed of 6 single rock-shaped mountain peaks, which are constructed using prefabricated steel structures.

Liao Dengzhi, staff member of the Natural Museum Project of Chengdu Tongjian Company: 100% prefabricated steel structure is used on the ground of the museum, which has the advantage of meeting the peculiar (modeling) design requirements of our museum, shortening the construction period and reducing the consumption of materials in our process.

The advantages of prefabricated buildings are not only reflected in complex public buildings, but also greatly improve construction efficiency. In Xindu District, Chengdu, with the completion of the last steel beam hoisting, the main structure of the first large-scale high-rise steel structure prefabricated residential community in China was officially capped. Its fastest construction speed has reached 3 days to complete 1 floor, and it has achieved maximum low-carbon emission reduction.

Zhao Nan, chief engineer of China Construction Science and Technology Workers' Housing and Talent Housing Project: Basically, 100% of steel can be recycled. In the production and construction stage, the amount of on-site construction measures is basically zero, and the carbon emissions of prefabricated steel structure houses are reduced by 50% compared with traditional cast-in-place buildings.

During the year, 58 million square meters of prefabricated buildings were newly started in Sichuan City

The reporter learned that the province will start new construction of 58 million square meters of prefabricated buildings throughout the year, and the comprehensive industrial scale is expected to exceed 1 trillion yuan. In particular, a number of prefabricated building production bases will also be put into use in various places.

He Ping, deputy general manager of Dazhou Huaxi Prefabricated Building Technology Co., Ltd.: The whole (prefabrication) process only takes 8 hours, all of which are factory-made, which ensures product quality, shortens the on-site construction period, reduces on-site wet work, and ensures environmental protection.

The reporter learned from the Provincial Department of Housing and Urban-rural Development that at present, 12 enterprises in Sichuan Province have been rated as national prefabricated building demonstration bases, and the annual production capacity of prefabricated concrete parts production bases has reached 5.8 million cubic meters. According to the plan, by 2025, the newly constructed prefabricated buildings in Sichuan Province will account for 40% of the new construction area, and the assembly rate of prefabricated buildings will not be less than 50%.
