Background

The insufficient thickness or the super thick concrete slab surface is a common problem in the building, is also a difficult problem to solve, and is often difficult to control in the actual construction process, for example: the thickness of the floor slab is insufficient and does not meet the design stress requirement, the thickness is too thick to enable the room to be insufficient in net height, and the individual inspection and acceptance cannot pass, so that the thickness of the slab is measured in the concrete slab surface pouring process, timely adjustment of the thickness is timely found, the thickness of the slab is effectively controlled, and the problem to be solved in the building industry is solved.

The Chinese patent of application number 200820113305.3 discloses a concrete plate thickness measurer in construction, wherein the lower end of a ruler body is a downward sharp corner, a ruler surface in the middle of the ruler body is provided with a size scale and a scale value, the upper part of the ruler body is provided with an operation handle, the middle of the ruler body is coated with a sliding block with a flat plate, the sliding block can slide in the middle of the ruler body, the indicating scale can be used for measuring the thickness of the plate at any time in the concrete plate pouring process, timely finding out and timely adjusting the thickness, and the measuring and controlling of the concrete pouring thickness are suitable for the concrete pouring process. However, this patent also has the following drawbacks: the scale value of the ruler body is gradually increased from bottom to top, when the thickness of the concrete needs to be read, a worker needs to bend down to be close to the surface of the concrete to read, and the ruler is inconvenient to use.

Detailed Description

The present utility model is further described below with reference to examples and fig. 1-4 for the purpose of facilitating understanding of those skilled in the art, and the description of the embodiments is not intended to limit the utility model.

Referring to fig. 1-4, a concrete thickness measuring tool comprises a flat and long measuring rod 1, a tip 11 is fixed at the lower end of the measuring rod 1, an upper roller 12 and a lower roller 13 are movably connected to the upper part and the lower part of the measuring rod 1 respectively, an annular tape 14 is connected between the upper roller 12 and the lower roller 13 in a transmission manner, a floating plate 2 which is in sliding connection with the measuring rod 1 is sleeved on the outer side of the measuring rod 1, the inner side of the floating plate 2 is fixedly connected with the bottom of the front end of the annular tape 14, a scale mark 15 and a scale value 16 are arranged at the front end of the annular tape 14, the scale value 16 gradually increases from top to bottom, the starting value of the scale value 16 is equal to the distance between the bottom end of the annular tape 14 and the bottom end of the tip 11, a visible window 17 is arranged at the top of the measuring rod 1 corresponding to the position of the annular tape 14, and indication arrows 18 are arranged at the centers of two sides of the visible window 17.

The concrete thickness measuring tool can measure the thickness of a concrete slab at any time in the process of casting the concrete slab, timely find and adjust the thickness, and read the thickness by transferring the reading at the bottom of the existing measuring rod 1 to the top of the measuring rod 1, and has the advantages of simple structure and convenient use.
