Problems solved by technology
However, the measurement method of the final pouring thickness of the floor concrete has limitations, and the height of the horse stool is also susceptible to objective influences, making it difficult to accurately measure, which eventually leads to large deviations in the thickness of the negative reinforcement protective layer and a low pass rate

Embodiment Construction
[0018] The present invention will be described below in conjunction with the accompanying drawings, and the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0019] refer to figure 1 As shown, the construction method for monitoring the thickness of the floor slab negative reinforcement protective layer of the present embodiment, the specific steps are as follows:
[0020] 1. Sheet production
[0021] 1.1 Use a machine tool to open a concentric hole at the center of the polyurethane rod (diameter 55mm, length 500mm). Since the polyurethane material has a certain plasticity, the size of the hole is set to 8.5mm for inserting a ribbed third-grade steel bar with a diameter of 8mm;
[0022] 1.2 Cut the polyurethane rod into 4mm thick slices with a machine tool, and the cutting speed is controlled at 2 pieces / min;
[0023] 1.3 Use red paint to mark on the sheet. The marked area ...

Abstract
The invention discloses a construction method capable of monitoring the floor slab negative reinforcement protection layer thickness. According to the construction method, an upper layer negative reinforcement of a floor slab is sleeved with a thin sheet from the side face, a mark is arranged on the side face of the thin sheet, the mark is arranged above the upper layer negative reinforcement, thedistance between the lower edge of the mark and the upper layer negative reinforcement is the protection layer thickness, and pouring is conducted on the concrete face of the floor slab till the position of the lower edge of the mark. By means of the construction method, the protection layer thickness can still be directly detected after the negative reinforcement is covered with concrete and hidden, and it is avoided that the deviation of the negative reinforcement protection layer thickness is excessively large.
Description
technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method for monitoring the thickness of a negative reinforcement protective layer of a floor slab. Background technique [0002] In the current cast-in-place reinforced concrete slab, the thickness of the protective layer of the negative reinforcement of the slab lacks a direct and efficient monitoring method. In traditional construction, the vertical position of the negative reinforcement is mainly determined by the steel horse stool, and the pouring concrete is inserted into the pouring concrete with a PVC sleeve to measure the pouring thickness of the concrete floor. Rib diameter. However, the measurement method of the final pouring thickness of the floor concrete has limitations, and the height of the horse stool is also susceptible to objective influences, making it difficult to measure accurately, which eventually leads to large devi...
