China Construction News丨Tang Xiuguo's special issue of the two sessions suggests: increase the application of prefabricated vertical concrete structure technology

Today, the special issue of the two sessions of China Construction News published Tang Xiuguo, president of Sany Group“Increase the application of prefabricated vertical concrete structure technology”recommendations. It reads as follows:

The development of prefabricated buildings is the only way for the construction industry to achieve high-quality development. At present, China's prefabricated buildings are developing rapidly and have formed a relatively mature one“Prefabricated horizontal members+Prefabricated enclosures with internal partition walls+Prefabricated decoration”as the main prefabricated building system, and gradually to“Smart Construction”for the core“Industrialization of new buildings”Healthy development in the direction. However, from the perspective of specific practice, most areas are still promoting the development of prefabricated buildings“Horizontal structure prefabrication+Other non-structural parts are prefabricated”Technology-based, the overall prefabrication rate of the main concrete structure is low, which has caused some impact on the promotion of the prefabricated concrete structure system and the comprehensive implementation of the national policy, and the promotion of vertical concrete structure prefabrication technology is urgent.

In general, at present, the vertical concrete structure prefabrication technology still has problems such as high cost, difficult installation, low construction efficiency, and difficult to ensure grouting quality. Here is a suggestion: on the one hand, construction enterprises should strengthen cooperation with universities and scientific research institutes, and vigorously innovate and experiment in technology; On the other hand, the government should increase the promotion of vertical concrete structure prefabrication technology, build a training platform, and encourage enterprise innovation in policy.

Sany Group, together with authoritative experts in the United Nations, has developed a to“cavity+Lap+Cast-in-place”for the coreSPCS3.0The prefabrication technology of vertical concrete structures has formed a group standardCECS579-2019It can realize the full prefabrication of walls, columns, beams and slabs, and the full assembly of underground and aboveground, greatly reducing labor needs, and achieving the goals of resource conservation, environmental friendliness, intelligent construction, and green development, and has completed the project in Hunan, Shanghai, Tianjin, Beijing, Shandong, Chongqing and other places, with a construction area of near10010,000 square meters, it is recommended that relevant government departments or institutions organize inspection, demonstration and promotion.
