Compared with the traditional building, the prefabricated building can greatly save resources, remarkably reduce construction energy consumption and emission, reduce construction waste and construction dust, improve engineering quality, realize the development of the building industry from a rough type to an intensive type, and have obvious green and low-carbon ecological effects.
Currently, the relatively mature structural systems commonly used in prefabricated buildings include precast concrete structures, steel structures, and steel-concrete composite structures. The prefabricated concrete structure material has low strength, heavy self-weight of components, complex connecting technology and poor integrity; the steel structure material has high strength, but the section of the member is small, the rigidity is weak, the corrosion resistance and the fire resistance of the material are poor, and fire prevention and corrosion prevention measures are additionally adopted; the steel-concrete combined structure integrates the advantages of the two systems, has the characteristics of high strength, high rigidity, light dead weight, corrosion resistance, fire resistance and the like, but is difficult to arrange a large amount of connecting steel bars when the components are connected, and can not meet the integral requirement of the traditional cast-in-place structure. The above disadvantages severely limit the application and development of fabricated building structure systems.
