Description

Technical Field

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

[0002] Corrugated steel plate concrete composite floor is a floor 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 searching, the patent number "CN220414636U" mentioned in the text that "the utility model discloses a corrugated steel plate concrete composite floor in the field of composite floor technology, including a corrugated steel plate, a concrete layer, a steel beam, a shear bolt, and a reinforcement device; the corrugated steel plate is a steel plate with a corrugated structure, and a plurality of connecting steel bars are crisscrossed to form a mesh structure. The corrugated steel plate, the shear bolt, the connecting steel bar, the shear steel rod and the reinforcement device are all cast and solidified inside the concrete layer, and the reinforcement device can be set, and the reinforcement device is locked on the steel beam together with the corrugated steel plate through the shear bolt, and the reinforcement devices on the same straight line are connected by the same connecting rod. The steel bar locking connection is subjected to overall force. Multiple connecting steel bars form a steel mesh on the corrugated steel plate and are pre-buried in the concrete layer, so that the entire steel mesh locks the concrete and the corrugated steel plate together on the steel beam, thereby improving the overall connection strength and the stability of the overall structure of the composite floor. This device enables the entire steel mesh to lock the concrete and the corrugated steel plate together on the steel beam, thereby improving the overall connection strength and the stability of the overall structure of the composite floor. However, the device has relatively weak protection for the surface of the steel plate, making it susceptible to corrosion and oxidation by the external environment, shortening its service life. At the same time, the sound insulation effect of the device is also relatively poor, resulting in the inability to provide users with a more comfortable living environment.
