Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering floor thickness detection devices, in particular to a floor thickness detection device which is easy to adjust. Background Art

[0002] The quality of concrete floor slabs is directly related to the overall safety and usability of the building. The thickness test of concrete floor slabs is mainly to ensure that the floor slabs reach the expected design thickness to ensure the safety and usability of the building. Once the thickness defects of the floor slabs are found during the test, effective measures should be taken in time to avoid future safety hazards and reduce the cost and time cost of subsequent repairs.

[0003] The thickness detection of concrete floor slabs is divided into two methods: direct measurement and indirect measurement. The direct measurement method is a relatively simple and clear detection method. A steel tape measure is used to measure the cross-sectional dimensions of the cast-in-place floor slab using the layout holes of each floor slab to assess whether the concrete floor slab meets the design requirements.

[0004] The traditional direct measurement method has the following problems in measurement: first, the steel tape measure will bend and it is difficult to accurately adjust the depth of the steel tape measure inserted into the hole to just reach the bottom of the hole, which will cause measurement errors; second, it is difficult to adjust the steel tape measure to be perpendicular to the floor slab when measuring in the hole, and the operator will have errors when marking the measurement position with his fingers during measurement, which will cause the steel tape measure to tilt and affect the measurement results. Therefore, this application proposes a floor thickness detection device that is easy to adjust. Utility Model Content

[0005] In order to overcome the problems in the background technology, the utility model provides an easily adjustable floor thickness detection device, which solves the problems that the steel tape measure will bend during measurement and it is difficult to accurately adjust the depth of the wire-laying hole to just reach the bottom of the wire-laying hole, and it is difficult to adjust to ensure that the steel tape measure is in a vertical state with the floor slab when measuring in the wire-laying hole, which will cause the steel tape measure to tilt and affect the measurement results.

[0006] A floor thickness detection device that is easy to adjust includes a measuring rod, a limit block, a traction ring, a traction line, and a positioning ring. The measuring rod is provided with scale lines. The limit block is arranged at the lower part of the measuring rod through a rotating shaft and vertically contacts the measuring rod. The traction ring is sleeved on the upper part of the measuring rod. The traction lines are respectively connected to the limit blocks and the other end is connected to the traction ring. The positioning ring is slidably installed on the measuring rod.

[0007] Furthermore, the lower part of the measuring rod is evenly spaced with storage grooves, and the limit block is installed in the storage groove by rotating the rotating shaft. The limit block rotates around the rotating shaft ° to contact and limit the bottom wall of the storage groove.

[0008] Furthermore, a level is mounted on the upper part of the measuring rod in a damping sliding manner.

[0009] Furthermore, the top of the measuring rod is threadedly connected with an anti-slip part.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The present application is provided with a measuring rod, a limit block, a traction ring and a traction line. After the bottom of the measuring rod reaches and extends out of the bottom of the wire-laying hole, the traction ring releases the traction line to expand the limit block, and the limit block can contact the bottom of the floor slab, and the measuring rod is accurately adjusted and controlled to reach the bottom of the wire-laying hole, and the measuring rod is made vertical, which solves the problem that the steel tape measure of the traditional direct measurement method will bend and it is difficult to accurately adjust the depth of the wire-laying hole to just reach the bottom of the wire-laying hole, resulting in measurement errors.

[0012] The present application is provided with a positioning ring and a spirit level. The spirit level makes it easy to observe whether the measuring rod is in a vertical state and to make timely adjustments. The positioning ring can position the measuring scale to avoid the operator marking with his fingers, thus solving the problem that the traditional direct measurement method is difficult to control the steel tape measure to be in a vertical state with the floor slab when measuring in the layout hole. When measuring, there will be errors in the measurement position by the operator marking with his fingers, which will cause the steel tape measure to tilt and affect the measurement result.
