Description

Industrialized steel tube bundle composite structure building system

Technical field

Background technique

The report of the 18th National Congress of the Communist Party of China proposed to vigorously promote the construction of ecological civilization. In January 2013, the General Office of the State Council forwarded the “Green Building Action Plan” of the Ministry of Development and Reform and the Ministry of Housing and Urban-Rural Development; the State Council [2013] No. 41 document required to resolve the production capacity. Serious excesses require the use of steel in the construction sector, and the industrialization of construction, especially the construction of steel structures, is imperative. The steel structure building system is an industrial green building product, which is in line with the current favorable policy situation of the country. The large-scale promotion of the steel structure system is conducive to the long-term sustainable development of the country. At present, in the domestic steel structure building system, the structural system is still trapped in the conventional steel support-frame system, steel frame-concrete core tube system, steel frame-steel shear wall system, etc. The existing steel structure system has structural steel. Insufficient quantity and high production cost; internal and external wall systems include aerated concrete blocks, grouting walls, and slab walls. In terms of cost, the current steel structure building system is generally higher than the concrete structure, which has become an obstacle to the widespread promotion of steel structure building systems, especially steel structure houses. In addition, the construction method of concrete structures requires many wooden formwork, which causes damage to forest resources and pollutes the environment. A large number of steel bars need to be manually tied, not an industrial production method.

The steel pipe bundle composite structure is a new type of steel and concrete composite structure, which better exerts the advantages of light weight and high strength of steel and high concrete rigidity, and avoids the disadvantages of poor stability of steel components, high brittleness of concrete and rapid degradation of stiffness. The steel pipe bundle combination structure is produced by an industrial production line, and the whole process can be operated by a robot. The steel pipe bundle combination structure is used for the shear wall. Since the steel and the concrete combination have good ductility, the length of the wall and the thickness of the thinned wall can be effectively increased, and the building adaptability is strong. The slab can be directly connected to the wall, eliminating the need to construct complex steel or concrete beams. The whole component does not need steel bars, the concrete is directly poured, and the template is not needed, and the construction speed is fast.

Summary of the invention

In order to overcome the shortcomings of the existing steel structure building system, such as large amount of steel, complicated production and poor economic performance, the present invention provides a new building system with economical steel volume, simple component fabrication, convenient and quick construction, and convenient industrial production.
