Technical Field

[0001] The invention relates to the technical field of construction engineering measurement, in particular to a floor slab thickness measuring device. Background Art

[0002] Concrete floor slabs play an important role in bearing and supporting in construction projects. In the current actual measurement and evaluation, the thickness of the floor slab is also an important indicator of the construction quality of concrete projects.

[0003] After searching, a Chinese patent with announcement number CN207487551U discloses a floor thickness measuring device, including an outer rod and an inner rod. The inner rod is provided with a scale along the axial direction. The outer rod is sleeved on the inner rod and can slide relative to the inner rod along the length direction of the inner rod. A radial positioning plate is provided on the outer rod. The invention can quickly obtain the thickness of the floor, help save measurement time, and ensure measurement accuracy.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] The above-mentioned search patent requires measuring the thickness at the mid-span position, which requires manual assistance under the floor slab after drilling. This is time-consuming and labor-intensive. In addition, for high-rise buildings and buildings that are inaccessible to manpower, manual assistance under the floor slab after drilling is impossible, resulting in low measurement accuracy. Therefore, there are certain limitations. Summary of the invention

[0006] In order to solve the above technical problems, the present invention proposes a floor thickness measuring device, which is easy to use and has high measurement accuracy.

[0007] The technical solution for achieving the purpose of the present invention is: a floor thickness measuring device, including a rotating shaft, a measuring rod is sleeved on the outside of the rotating shaft, scale lines are fixedly installed on the surface of the measuring rod, a vernier caliper is sleeved on the outside of the measuring rod, and a screw is threadedly installed on one side of the vernier caliper.

[0008] Preferably, a plurality of curved grooves are provided at the bottom of the rotating shaft, and a base is fixedly mounted on the bottom of the rotating shaft and the measuring rod.

[0009] Preferably, a plurality of one-way grooves are provided on the surface of the base, each of the one-way grooves corresponds to the curved groove, and a telescopic block is slidably mounted on each of the one-way grooves.

[0010] Compared with the prior art, the present invention has the following significant advantages:

[0011] First, the present invention facilitates thickness measurement and avoids manual secondary construction, which not only improves measurement efficiency and accuracy but also speeds up construction, thus having good economic benefits.

[0012] Second, the shaft part of the present invention is a rotary telescopic structure, and the measuring rod is connected to the main body part through a data line, which can be telescopic and rotatable, thereby improving the flexibility and practicality of the device, saving materials and resources.

[0013] The invention solves the existing problem that under normal circumstances, manual assistance is required for measurement, but when the floor is too high, manual assistance cannot be used to solve the problem, the measurement is inconvenient, the speed is slow, and the accuracy is poor.
