Building with prefabricated reinforced concrete support

Abstract

The invention provides a building with a prefabricated reinforced concrete support. The building comprises the prefabricated reinforced concrete support, a prefabricated column frame, prefabricated main beams, cavity floor components, joint shallow seams between the cavity floor components, and wallboards. The building is characterized in that the prefabricated reinforced concrete support is rhombic, and rhombic corner angles are provided with main beam assembly ends; a square column hole is formed in the middle of the prefabricated reinforced concrete support, the prefabricated column frame is a thin-wall frame, and the thickness of the thin-wall frame is smaller than or equal to 50 mm; wallboard connecting pieces are mounted on the outer surface of the prefabricated column frame, and thecavity floor components are hexagonal and comprise longitudinal reinforced concrete ribbed beams, transverse reinforced concrete ribbed beams, cavities and steel mesh concrete lower flange thin boards; and longitudinal ribbed grooves and the shallow joint seams are formed between the cavity floor components, and the wallboards are transverse wallboards.

Description

technical field [0001] The invention relates to an assembled building system technology, in particular to a building with a prefabricated reinforced concrete support. Background technique [0002] In order to adjust the structure of the construction industry, improve the quality of construction, speed up construction, achieve energy conservation and environmental protection, and reduce project costs, the state has proposed to vigorously promote prefabricated buildings and specified specific implementation plans; Wall structure, steel structure and steel-concrete composite structure system are widely used, and the structural system and application field of my country's prefabricated building are clarified; however, the prefabricated building with long-span reinforced concrete frame structure has just started, and ordinary laminated floors are used. And the double T-slab floor technology leads to high cost and ungroundedness, which restricts the development of the prefabricated ...

Problems solved by technology

[0004] In order to promote the development of housing industrialization in China, the inventor applied for ZL201620408935.8 "passive building energy-saving integrated system", which extended the cast-in-place concrete hollow floor to the field of prefabricated buildings through creation and transformation, and solved the overall problem of prefabricated building structures. problems such as poor performance, long-span unidentified beams, oversized components, industrialization of components, controllability of building quality, work efficiency and environmental protection; although these inventions have laid the foundation for the industrialization of housing in my country, there are still long strips of prefabricated assemblies. The unidirectionality of the stress on the cavity slab, the cracks in the gap when two prefabricated cavity slabs are put together, and the limited connection space of the transverse reinforcement of the two-way stressed cavity floor, etc.

[0005] In order to overcome the difficulty of low assembly rate of reinforced concrete prefabricated building structures, the inventor applied for 201710951186.2 "a prefabricated building structure", which increased the assembly rate from less than 40% to more than 70%, passed the national test and acceptance, and ensured structural safety Strong and economical, it has played an active role in the government's promotion of prefabricated buildings; however, the beams, columns, and floor nodes are all in the cast-in-place state. Although the structure is safe, it requires a large number of temporary supports to support the beams, col...
