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, columns, and floor components. There are many steel bar joints at the intersections of beams and beams, and beams and columns, and the steel bar connections are cumbersome and expensive

[0006] At present, there are still many technical problems unresolved in the prefabricated buildings of reinforced concrete frame structure, resulting in high construction costs and hindered promotion; therefore, the inventors have tested and verified the beams, columns, In the cast-in-place concrete node area of ​​the floor slab, the creative change lies in the prefabricated reinforced concrete support body, which enhances the ability of shear force and punching resistance. On the assembly end of the main beam set on the rhombus-shaped or triangular-shaped water chestnut outside the support body; the column stress reinforcement passes through the criss-cross beam reinforcement reinforcement in the square column hole in the middle of the prefabricated reinforced concrete support to extend upwards, realizing the beam reinforcement. , There is no steel joint at the node of the column, which greatly reduces the number of supporting rods and further speeds up the assembly, improves the quality of the assembly, and reduces the cost of the project; realizes a new overall structure of the prefabricated building with strong columns and weak beams and then pouring the flange laminated layer on the floor It is a major breakthrough in the new technology system of prefabricated buildings with reinforced concrete frame structure, and has become an urgent need for innovation in the field of prefabricated construction technology.
