Description

Technical Field

[0002] The composite slab is an assembled integral floor slab made of prefabricated slabs and cast-in-place reinforced concrete layers. The composite slab has good integrity, and the upper and lower surfaces of the slabs are flat, which is convenient for the decoration of the finishing layer. It is suitable for high-rise buildings and large-span buildings that have high requirements for overall rigidity.

[0003] Upon checking the announcement number: CN217105759U, a prefabricated bidirectional prestressed concrete composite slab is disclosed. This technology discloses that "it is mainly composed of pre-tensioned prestressed steel bars and composite slab concrete cast between the pre-tensioned prestressed steel bars, and also includes post-tensioned prestressed steel bars, and the post-tensioned prestressed steel bars and the pre-tensioned prestressed steel bars are staggered in longitude and latitude; the composite slab concrete is cast between the post-tensioned prestressed steel bars and the pre-tensioned prestressed steel bars to form the composite slab and other technical solutions. Since the characteristic of prestressed concrete components is good crack resistance, the cross-sectional size of the component can be reduced under the condition of meeting the reinforcement ratio, thereby reducing the amount of concrete, and further reducing the self-weight of the component; it has the characteristics of reducing the amount of steel and saving costs under the premise of meeting the reinforcement ratio. In addition, the two-way slab is more reasonably stressed than the one-way slab, which is more conducive to the safety of the structure and other technical effects."

Moreover, when the prestressed concrete precast composite panels of the prior art are used for construction, most of the prestressed concrete precast composite panels have poor sound insulation performance, which makes it easy for users inside the building to be disturbed by noise after the building is completed.
