Abstract

The invention discloses a detachable floor system connecting joint for a modular steel structure and a manufacturing method thereof. The connecting joint comprises modular ceilings, modular floor slabs and ceiling slab beam connecting assemblies. According to the detachable floor system connecting joint for the modular steel structure and the manufacturing method thereof, detachable floor system connecting structures are arranged at the joints between the adjacent modular ceiling slab beams, horizontal connection between modular units is enhanced, and the problems that when the modular units on the same layer are spliced, due to the fact that the floor slabs are discontinuous, the modular steel structure is excessively deformed in the plane, and the rigidity in the plane of the floor slabs is insufficient are solved; and meanwhile, the welding parts of the connecting structures are completed in a factory in advance, after the connecting structures are transported to the site, high-strength bolts are adopted for on-site assembly, no welding exists on the site, when the service life of the structure is due and the structure needs to be disassembled, the adjacent modular units can be separated by unscrewing the high-strength bolts, the overall stress performance of the modular steel structure can be considered on the premise that the assembly advantages of a modular building are exerted, and the integrity, construction convenience and detachability of the modular steel structure are guaranteed.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a detachable floor connection node for a modular steel structure and a manufacturing method. Background technique [0002] The prefabricated steel structure system is a building unit or component manufactured according to uniform and standard building part specifications. It is a building produced after prefabricated production in the factory and then transported to the construction site for assembly. It has the advantages of energy saving, environmental protection, fast construction speed, and high degree of industrialization. The development of industrialized prefabricated steel structure system is an urgent requirement of my country's green building and building industrialization. Modular steel structure is a highly integrated prefabricated building. After prefabricating the beams, plates, columns, walls and other components in the modular units in the factor...
