Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, specifically relates to a concrete floor thickness control tool convenient for measuring thickness. BACKGROUND

[0002] At present, the management and measurement of concrete floor thickness generally rely on two technical means, namely, the reinforcement bar observation method and the secondary hole opening method. However, these two methods have exposed a series of problems and deficiencies in the actual application process.

[0003] Specifically, although the reinforcement bar observation method can realize the preliminary control of floor thickness to a certain extent, its operation process is relatively complicated, and the technical level of the construction personnel is required to be high. At the same time, this method performs poorly in controlling the overall flatness of the floor, and it is difficult to ensure the uniformity and consistency of the floor thickness.

[0004] The secondary hole opening method is a post-measurement means after the completion of floor pouring. Although this method can intuitively obtain the data of floor thickness, it is easy to cause the risks of punching through the line pipe and damaging the floor structure during the hole opening process, thereby causing the quality problems such as floor leakage. In addition, the hole opening operation also increases the additional construction cost and construction period, and reduces the economic benefit of the project.

[0005] In summary, the existing concrete floor thickness control has certain limitations in practicability and economy. Moreover, it is not convenient for assisting the measurement of the thickness of the concrete floor in the later stage. SUMMARY

[0006] The utility model provides a concrete floor thickness control tool convenient for measuring thickness to solve the technical problem that the concrete floor thickness control in the prior art is poor in practicability and flexibility and inconvenient for assisting the measurement of the thickness of the concrete floor in the later stage.

[0007] To solve the above problems, the concrete floor thickness control tool convenient for measuring thickness provided by the utility model adopts the following technical scheme:

[0009] The network layer fixed and supported by the positioning sleeve is further included, and the network layer is used for limiting the thickness of the concrete floor. The positioning sleeve includes an inner sleeve pipe and an outer sleeve pipe rotatably arranged outside the inner sleeve pipe. One side of the outer sleeve pipe is provided with a connecting piece for fixing the network layer.

[0010] Further, the bottom outer wall of the inner sleeve is provided with an annular boss, and the inner wall of the outer sleeve is provided with an annular groove corresponding to the annular boss.

[0011] Further, the bottom surface of the outer sleeve is flush with the bottom surface of the inner sleeve, and the bottom surface of the inner sleeve abuts against the upper surface of the PVC plastic pipe.

[0012] Further, the network layer is a mesh structure formed by cotton threads, and connecting threads for external hanging are arranged at four corners.

[0013] The connecting piece is a lug arranged on one side of the outer sleeve, and the connecting piece is provided with a connecting hole.

[0014] Further, the bottom surface of the outer sleeve is provided with a lug for positioning the connecting thread, and the opening of the lug faces the PVC plastic pipe.

[0015] Further, the upper surface of the bottom of the lug is formed by a slope surface.

[0016] Further, the outer wall of the positioning column is provided with an external thread, the inner wall of the inner sleeve is provided with an internal thread, the inner sleeve is detachably sleeved on the positioning column through the threads, and the height of the inner sleeve on the positioning column is adjustable.

[0017] The concrete floor thickness control tool provided by the utility model has the beneficial effects that:

[0018] 1.

This effectively avoids the problem of entanglement and interference of the connecting thread in the rotation process, and ensures the smooth progress of the adjustment work.

[0021] 4. In the utility model, the lug arranged on the bottom surface of the outer sleeve not only further assists in leveling the network layer, but also ensures the horizontal consistency of the network layer and the top end of the PVC plastic pipe.
