Steel structure residence is the future development trend, it should be applied in ordinary residenc

The assembly building and high quality development seminar was held in Nanjing recently. Many experts in the industry believe that the assembly steel structure building has broad prospects and is expected to enter the ordinary residential buildings on a large scale in the future.

Speaking of "assembly building", the industry figuratively compares it to a house built like "building blocks". First, the columns, beams, floors, walls, stairs and other building components of the building are machined and formed in the factory, and then the prefabricated parts and components are transported to the construction site for assembly. Assembled building is a green construction technology, which has the characteristics of safety, high efficiency, energy saving, environmental protection and labor saving.

It is reported that in the three material systems of concrete, steel structure and wood structure used in assembly building, steel structure building will become the future trend based on the characteristics of safety, environmental protection, energy saving and recyclable utilization. This type of building is not unfamiliar. The Eiffel Tower in France and the Peace Hotel in Shanghai are all constructed of steel structure, which is still very safe in the past 100 years.

Experts at the meeting believed that, compared with traditional building methods, assembly building is more energy-saving and environmental protection, factory fluidized operation mode greatly improves the efficiency of operation, but also reduces costs.

Yu Kuangbao, Vice President of Hangxiao Steel Structure Co., Ltd., said: "Steel structure is a way of assembly building. For a 32-storey residential project, 60 workers can complete the construction of the main structure in 58 days. The construction speed is much faster than that of the traditional construction method. During the whole construction process, concrete garbage, construction sewage and sewage are reduced. Dust pollution."

Jiang Huancheng, academician of the Chinese Academy of Engineering, said that the assembled steel structure residence has broad prospects and will be able to enter the ordinary residence on a large scale in the future. At present, it has formed a certain scale in China, but it still needs to be explored continuously at the technical level.

It is understood that Hangxiao steel structure is constantly exploring in technology. The new generation of "concrete filled steel tube shear wall structure" developed by Hangxiao steel structure can adapt to different layout of building units, realize standardized design, industrialized manufacture, mechanized installation of components, easy to control engineering quality, save energy and protect environment, and has been gradually applied to Hangzhou Qian. Jiangshicheng Special Housing for Talents, Baotou Wanjun Metropolitan City, Yipin B District of Baoding City, Hebei Province, Penglai New Port Community, Shandong Province, and many other residential buildings.

"Concrete-filled steel tubular shear wall structure is a new structural system developed on the basis of rectangular concrete-filled steel tubular structure. It integrates the characteristics of rectangular concrete filled steel tubular structure, and has the advantages of large stiffness of shear wall structure and easy to meet the changeable layout of residential buildings. Li Wenbin, Chief Engineer of Century Home in Wuhan and a well-known expert on light steel structure in China, introduced the science and technology demonstration project of the Ministry of Housing and Construction.

He believes that the technology of concrete-filled steel tube bundle shear wall structure has been more and more popular. I believe that in the near future, this technology will be widely used in the market like rectangular concrete-filled steel tube structure and steel truss floor deck.
