Background Art

Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc., and are representatives of modern industrialized production methods because they use standardized design, factory production, assembly construction, information management, and intelligent applications.

CN201611181495.8 discloses a prefabricated concrete wall panel and an assembled building and a construction method thereof, wherein the sides with longitudinal side holes in the prefabricated concrete wall panels of the building are butted together to form a plurality of large wall panels, and the sides with longitudinal side holes of the plurality of large wall panels are butted together to form a wall body; vertical steel mesh or steel cage is arranged in the longitudinal holes of the wall body; "L"-shaped cast-in-place columns are arranged at the corners of the wall body, and "T"-shaped cast-in-place columns are arranged at the "T"-shaped intersections of the wall body; horizontal steel bars are passed through the through holes formed by the transverse holes of two adjacent prefabricated concrete wall panels; the prefabricated concrete wall Horizontal steel bars are inserted into the through holes formed by the transverse holes at the junction of the transverse holes of the slab and the "L"-shaped cast-in-place columns or "T"-shaped cast-in-place columns, and the inserted horizontal steel bars extend into the edges of the "L"-shaped or "T"-shaped cast-in-place columns; the horizontal steel bars inserted into the through holes and the horizontal steel bars of the wall of the steel cage in the wall panel form a lap connection that meets the lap connection length required for high-rise buildings; the horizontal steel bars inserted into the transverse holes between the concrete prefabricated wall panel and the "L"-shaped cast-in-place columns or "T"-shaped cast-in-place columns and the horizontal steel bars of the steel cage in the prefabricated wall panel form a lap connection that meets the requirements of high-rise buildings; concrete is poured in the holes.

The prefabricated wall panels and assembled buildings in the above patent application are usually used for high-rise residential buildings and are not suitable for the rapid construction of low-rise houses. Moreover, the prefabricated wall panels do not contain insulation structures, and insulation decorative panels need to be installed separately on the outer surface of the building after the construction is completed.

Therefore, developing and designing a low-rise energy-saving and heat-insulating concrete house that can be built quickly has become one of the technical problems that need to be solved urgently in this field.
