Description

Technical Field

[0001] The utility model relates to the technical field of composite floor slabs, in particular to a profiled steel sheet concrete composite floor slab. Background Technique

[0002] The profiled steel sheet concrete composite floor slab is a floor slab system with high structural strength, good rigidity, light weight, high construction efficiency, good fire resistance and low maintenance cost. It is widely used in various building types, such as commercial buildings, industrial buildings, residential buildings, etc.

[0003] After retrieval, the text of the patent number "CN220414636U" mentions that "the utility model discloses a profiled steel sheet concrete composite floor slab in the technical field of composite floor slabs, including profiled steel sheets, concrete layers, steel beams, shear studs, and reinforcement devices; the profiled steel sheets are steel sheets with a corrugated structure, and multiple connecting steel bars are criss-crossed to form a mesh structure. The profiled steel sheets, shear studs, connecting steel bars, shear steel bars, and reinforcement devices are all cast and solidified inside the concrete layer. By setting the reinforcement device, the reinforcement device is locked on the steel beam together with the shear studs through the profiled steel sheets. The reinforcement devices on the same straight line are locked and connected into an integral force through the same connecting steel bar. Multiple connecting steel bars form a steel bar mesh on the profiled steel sheets and are embedded in the concrete layer, so that the entire steel bar mesh locks the concrete and the profiled steel sheets together on the steel beam, improving the overall connection strength and the stability of the overall structure of the composite floor slab". This device locks the concrete and the profiled steel sheets together on the steel beam through the entire steel bar mesh, improving the overall connection strength and the stability of the overall structure of the composite floor slab. However, the protection of the steel sheet surface by this device is relatively weak, resulting in its susceptibility to corrosion and oxidation in the external environment, shortening the service life. At the same time, the sound insulation effect of this device is also relatively poor, resulting in the inability to provide a more comfortable living environment for users.
