Description

Fixing structure and method for steel structure residential composite floor slab and overhead floor

Technical Field

The invention relates to the technical field of building construction, in particular to a structure and a method for fixing a composite floor slab and an overhead floor slab of a steel structure house.

Background

With the increasing living standard of people, the construction industry has been greatly developed, and more buildings begin to use concrete composite floor slabs. The laminated floor slab is an integral assembled floor slab formed by laminating prefabricated slabs and cast-in-place reinforced concrete layers, has good integrity, smooth upper and lower surfaces of the slabs, is convenient for finishing a finish coat, and is suitable for high-rise buildings and large-bay buildings with higher integral rigidity requirements. However, the conventional supporting scheme of the composite floor slab supporting system is a floor support, which affects the flow process, has low working efficiency, and is easy to cause the mold expansion phenomenon when the support is not in place.

In addition, the traditional building is not easy to overhaul, maintain and adjust due to the fact that pipelines are embedded in the structure body in advance, and a novel assembly type steel structure house capable of separating the pipelines from the building structure body is needed. The effect of pipeline separation can be achieved by adopting the overhead floor building form, and meanwhile, the vibration of the ground is reduced. Conventional interior walls are typically rigidly fixed to the floor and are not easily re-compartmentalized to the dwelling.

Through retrieval, the Chinese patent application number: 2018110489915, the name of invention creation is: floor chassis, built on stilts floor system and the laying method of this system, application publication date: in the application, the side surface of the floor chassis is provided with the connecting structure in 17 months 3 in 2020, and when the floor is installed, the adjacent raised floors can be fixed through the connecting structure, so that the raised floors are prevented from horizontal displacement, and the stability of the raised floor system is improved. The chassis is in a hollow frame shape, so that the use amount and the self weight of metal materials of the chassis are reduced, and the operation and the installation are convenient; the chassis has highly different first platform and second platform, and the cement infill panel is laid on first platform, and the ceramic tile is laid on cement infill panel and second platform, because ceramic tile and cement infill panel are fixed by metal material's chassis all around, consequently, raised floor bearing capacity is great, and the hollowing is not obvious to, the ceramic tile is difficult to take place to crack all around. It will be appreciated that the raised floor of this application can be removed to provide the partition in place, but the partition is constructed in a manner that requires a change in the structure of the floor pan, which is cumbersome to modify.
