When casting the concrete structural slab, the circular steel plate 4 will move upward under the influence of the thickness of the concrete structural slab, and the thickness of the concrete structural slab is judged by reading the position of the circular steel plate 4 outside the bottom end of the column steel bar 1. If the circular steel plate 4 is within the range of the standard thickness coating mark 13, it means that the thickness of the concrete structural slab meets the requirements of the specification.

The column steel bar 1 passes through the center of the circular steel plate 4 and the support sleeve 12, and the scale coating marks 14 on the outer surface of the column steel bar 1 are evenly distributed.

[0025] The working principle and use process of this utility model:

[0026] During concrete pouring, when the assembled control device is used, the column steel bar 1 is vertically inserted into the concrete structure slab being poured, and the position of the column steel bar 1 is adjusted to ensure that the central bubble of the universal horizontal bubble 3 on the end of the column steel bar 1 is always in the center position;

[0027] As the concrete is continuously poured, the circular steel plate 4 moves upward due to the increasing thickness of the concrete structure plate, and the circular steel plate 4 drives the flat full-screw suspension bar 5 to move upward;

[0028] The thickness of the concrete structure slab is determined by reading the position of the circular steel plate 4 outside the bottom end of the column steel bar 1. If the circular steel plate 4 is within the range of the standard thickness coating mark 13, it means that the thickness of the concrete structure slab meets the specification requirements.

[0029] The fixed sleeve 2 at the end of the column reinforcement 1 is rotated to drive the circular steel plate 4 to rotate, and the flat full-screw hanging bar 5 rotates to form a circular surface. During the rotation process, observe whether the gap between the flat full-screw hanging bar 5 and the surface of the concrete structure plate is uniform. If the flat full-screw hanging bar 5 forms scratches on the concrete surface, it means that the flatness error of the structure plate is too large;

[0030] Similarly, as the concrete is poured, measurements are taken in sequence to control the thickness and flatness of the concrete pouring slab.

[0031] To sum up: the control device of the present application has a simple structure, is easy to disassemble and assemble, and is easy to operate and use. It can be measured at any time during the concrete pouring at the construction site to control the thickness and flatness of the concrete pouring slab, avoid the poured concrete slab thickness exceeding the standard, and prevent the surface of the concrete pouring slab from arching.
