Description

Technical Field

[0001] The utility model relates to the technical field of composite slab surface casting, in particular to a composite slab casting thickness control mechanism. Background Art

[0002] Composite slabs are assembled integral slabs made of precast slabs and cast-in-place reinforced concrete layers. Composite slabs have good integrity, and the upper and lower surfaces of the slabs are flat, which is convenient for finishing layer decoration. They are suitable for high-rise buildings and large-span buildings that require high overall rigidity. Composite slabs are both one of the components of the slab structure and a permanent formwork for cast-in-place reinforced concrete composite layers. Horizontal equipment pipelines can be laid in the cast-in-place composite layers. When pouring the cast-in-place reinforced concrete layer of the composite slab, in order to control its thickness, it is necessary to set elevation control points, and then control its thickness through the distance between the elevation control points and the precast slabs.

[0003] For example, the authorization announcement number is CN217106203U, the authorization announcement date is 2022.08.02, and the name is "A composite floor thickness control device", which includes a composite floor body, the composite floor body includes a precast slab, the precast slab is a concrete slab, and five floor thickness controllers are arranged on the surface of the precast slab near the four top corners and the center, the lower end of the floor thickness controller is cast in the precast slab, and a cast-in-place slab is arranged at the top surface of the precast slab, and the upper end of the floor thickness controller is cast in the cast-in-place slab, the floor thickness controller includes a floor thickness control rod, a lower limit plate is arranged at the bottom surface of the floor thickness control rod, and a lower limit hole matching the lower limit plate is arranged at the inner side of the precast slab.

[0004] The traditional elevation control device uses steel bars fixed on the frame bars on the composite floor to achieve elevation, but this fixing method can easily cause the elevation steel bars to be skewed during pouring, affecting the pouring accuracy. The above application directly casts the thickness controller on the prefabricated composite floor. Although it avoids deviations in thickness control during pouring, it causes bulges on the composite floor, which makes it inconvenient to store and transport the composite floor.
