technical field

The utility model relates to the technical field of steel structure houses, in particular to a steel structure assembly house with a prefabricated floor plate embedded in a bathroom.

Background technique

At present, there are mainly three types of steel structure residential technologies on the market: one is low-rise light steel keel residential technology; the second is medium and high-rise steel structure support system + block wall; the third is medium and high-rise steel structure support system + Lightweight wall panel technology; the first technology is relatively mature, but because the main structure adopts cold-formed thin-walled steel with limited bearing capacity, it is not suitable for multi-storey and high-rise buildings, and it is difficult to promote on a large scale. The second type is far from the concept of building industrialization due to the large amount of on-site masonry work and does not conform to the future development direction. The third technology is still in development and is far from mature, and there are still some technical problems. The biggest problem is that both the inner and outer walls are made of grouted lightweight wall panels, which is easy to cause structural displacement at the connection of the main structure. This phenomenon is particularly prone to occur in some high-rise residential buildings, and this problem is more prominent in some pilot communities that have been built. In addition to the three structures described above, there is also an embedded steel structure assembly building system, which is a green new type of assembly steel structure building system based on the modular "double module" coordination and "module combination" technology It is the main feature of the building and an industrialized building technology system characterized by embedded steel structures and PC panels. This technology runs through the entire process of building (residential) design, processing, installation, equipment installation, decoration, and smart home. The industrialization, intensification and socialization of the whole process of building construction have been realized, but the existing built-in steel structure assembly houses still have the problem that the floor slab of the bathroom has not been customized, and follow-up construction is still required. For this reason, we propose a A prefabricated floor slab embedded steel structure assembly house with bathroom.
