Prefabricated concrete steel structure composite building structure and manufacturing method thereof

Abstract

The invention relates to the field of building, and discloses a prefabricated concrete steel structure composite building structure and a manufacturing method thereof. The prefabricated concrete steelstructure composite building structure comprises at least two prefabricated concrete plate assemblies arranged side by side at intervals, a pouring plate and a self-leveling layer. Each prefabricatedconcrete plate assembly comprises a concrete plate and a steel beam, and the steel beam is fixedly connected with the side of the concrete plate. The top portions of the steel beams of adjacent two prefabricated concrete plate assemblies are fixedly connected with each other. A pouring groove with an upward groove opening is formed by the coordination of the side walls of the concrete plates fixedly connected with the steel beams and the top portions of the steel beams. The pouring plate is poured and molded in the pouring groove. The self-leveling layer covers the upper surfaces of the prefabricated concrete plate assemblies and the pouring plate. Compared with a steel structure building floor, the prefabricated concrete steel structure composite building structure has the advantages that the rigidity is high, the structure is stable, and the self-leveling layer is not prone to falling off and damaging. According to the prefabricated concrete steel structure composite building structure and the manufacturing method thereof, only the pouring plate needs to be poured and molded, so a large-area pouring construction is not needed. After the prefabricated concrete plate assemblies are arranged side by side at intervals, the staff can conduct other constructions simultaneously, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a prefabricated concrete and steel structure composite building structure and a manufacturing method thereof. Background technique [0002] Modular building is an emerging building structure system, which uses each room as a modular unit, which is prefabricated in the factory, transported to the site after completion, and assembled into a whole building through reliable connections. [0003] Most of the existing modular workshops are constructed with steel structures, and the floors are mostly made of steel plates. However, for some industrial plants with special requirements, steel structure floors have many disadvantages. For example, pharmaceutical workshops have requirements for the cleanliness of the ground, so it is usually necessary to consider laying an epoxy mortar surface. However, the thickness of the epoxy mortar is relatively thin, and it cannot form a good adhes...

AI Technical Summary

Problems solved by technology

However, the thickness of the epoxy mortar is relatively thin, and it cannot form a good adhesion with the steel plate, which may easily cause the surface layer of the epoxy mortar to fall off and be damaged; at the same time, due to the insufficient rigidity of the steel plate, when personnel activities and equipment or material carts move, It is also easy to cause the epoxy mortar surface layer to crack and fall off.

Therefore, the steel structure floor with epoxy mortar surface layer cannot meet the special requirements of production or working environment

Although there are some modular factory buildings that use on-site concrete pouring to form concrete floors to solve the above problems, the maintenance period after pouring concrete is long, and other installation work in the construction process needs to wait until the concrete reaches a certain strength, which reduces the construction cost. efficiency
