Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete slab thickness measurement, and specifically relates to a simple tool for measuring the thickness of reinforced concrete slabs. Background Art
[0002] The thickness of a reinforced concrete slab is an important item in the inspection of structural entities. The generally common method for measuring the thickness of a concrete slab is as follows: First, use an electric drill to make a hole. One person uses a jack to support under the hole at the bottom of the slab, and another person inserts a straight rod-shaped measuring tool into the hole, makes a mark on the tool, and then uses a tape measure to measure the length from the bottom of the rod to the mark, which is the thickness of the slab at that place. This method is simple and easy to operate, but it requires two people to cooperate, and it is difficult to communicate up and down the building. Moreover, for some high-rise buildings with a large number of floors, using a jack is time-consuming and laborious, and the efficiency is low. Content of the Utility Model
[0003] In view of the above-mentioned prior art, the utility model provides a simple tool for measuring the thickness of a reinforced concrete slab.
[0004] A simple tool for measuring the thickness of a reinforced concrete slab provided by the utility model includes a measuring rod. The bottom of the measuring rod is rotatably connected with a clamping block. The lower part of the clamping block is heavier than its upper part. A notch is arranged at the top of one side of the clamping block. A protrusion is arranged on the measuring rod, and the protrusion is used to limit the rotation range of the notch.
[0005] Preferably, the cross-section of the measuring rod is rectangular, and a scale is arranged on the measuring rod.
[0006] Preferably, a cross-shaped limiting rod is arranged at the top of the measuring rod.
[0007] Preferably, hinge holes are arranged on both the measuring rod and the clamping block, and the measuring rod is hinged to the clamping block.
[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: The utility model provides a simple tool for measuring the thickness of a reinforced concrete slab, which is easy to carry, can be operated by one person, directly obtains the slab thickness data, and can also perform basic length measurement work in the unfolded state.

[0013] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] Embodiment: As Figures 1 - 2 shown, a simple tool for measuring the thickness of a reinforced concrete slab includes a measuring rod 1. The cross-section of the measuring rod is rectangular. A scale graduation 2 is provided on the measuring rod 1. A cross-shaped limiting rod 3 is provided at the top of the measuring rod 1 to prevent the measuring rod 1 from falling from the measuring hole. The bottom of the measuring rod 1 is rotatably connected with a clamping block 4. Hinge holes 5 are provided on both the measuring rod 1 and the clamping block 4. The measuring rod 1 and the clamping block 4 are hinged through the hinge holes 5. A notch 6 is provided at the top of one side of the clamping block 4. A protrusion 7 is provided on the measuring rod 1. The protrusion 7 is used to limit the rotation range of the notch 6. The bottom of the clamping block 4 is heavier and can naturally hang down under the action of gravity. The protrusion 7 makes the clamping block 4 and the measuring rod 1 in the same straight line.
[0015] When the simple tool is working, the measuring rod 1 is inserted into the measuring hole until the clamping block 4 is at the bottom of the concrete slab. The measuring hole is obtained by manual drilling and cannot guarantee complete perpendicularity. When the measuring rod 1 is in the measuring hole, the clamping block 4 shows different movement modes due to the inclination direction of the measuring hole. As Figure 3 shown, due to the inclination angle of the measuring hole, at this time, the placement direction of the measuring rod 1 causes the clamping block 4 to rotate under the action of gravity, and the clamping block 4 cannot return to the initial position parallel to the measuring rod 1. At this time, the measuring rod 1 is lifted upward, and the clamping block 4 will be stuck at the bottom of the concrete slab, parallel to the bottom of the slab, and the whole tool enters the measuring state to achieve the purpose of measuring the slab thickness. As Figure 4 shown, the placement direction of the measuring rod 1 is opposite to Figure 3 that in . Due to the inclination angle of the measuring hole, at this time, the clamping block 4 returns to the initial state parallel to the measuring rod 1 under the action of gravity, and the measuring rod 1 can be retrieved from the measuring hole.
[0016] The above is only the implementation mode of the present utility model, and does not limit the patent scope of the present utility model accordingly. All equivalent solutions made by using the content of the specification of the present utility model, directly or indirectly applied in other related technical fields, are equally within the patent protection scope of the present utility model.
