Description

Technical Field

[0002] Composite floor slabs are prefabricated monolithic floor slabs composed of precast slabs and cast-in-place reinforced concrete layers. The precast slabs are both a component of the floor slab structure and a permanent formwork for the cast-in-place reinforced concrete composite layer, allowing for the installation of horizontal equipment pipelines. Composite floor slabs offer good overall integrity and rigidity, saving on formwork, and their smooth upper and lower surfaces facilitate finishing. They are suitable for high-rise buildings and large-span buildings requiring high overall rigidity.

[0003] The authorization announcement number CN213766357U discloses a precast solid-form composite slab, in which the steel mesh is formed by connecting a number of horizontal steel bars and a number of vertical steel bars arranged perpendicularly to each other, and the intersections of the horizontal and vertical steel bars are welded and fixed. By replacing the steel bar binding with welding of the intersecting horizontal and vertical steel bars, this structure can improve the connection speed and load-bearing capacity to a certain extent.

[0004] Current technology is not comprehensive and has the following drawbacks: In prefabricated buildings, traditional same-floor drainage construction is usually carried out on-site by casting a partial concrete in the bathroom area of ​​the residential building or by using composite floor slabs.
