The use of elevation control points for laying out lines, pulling lines or other methods affects the concrete construction operation and causes a large amount of manpower and material resources to be wasted. The concrete thickness in some areas is insufficient or the flatness is poor, which seriously affects the structural safety and acceptance requirements. A simple device for measuring the concrete elevation of the floor slab is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A simple device for measuring the elevation of floor concrete comprises a bracket and a disc, wherein a vertical rod is arranged on the disc, a thread is provided on the surface of the vertical rod, the vertical rod is slidably connected to the upper surface of the bracket, and two nuts are threadedly connected to the vertical rod;

[0007] A connecting cavity is fixedly connected to the bracket, a cleaning component is installed between the connecting cavity and the disc, the cleaning component includes a sleeve, a scraper, and a rack plate, the sleeve is rotatably connected to the vertical rod, a scraper is fixedly connected to the upper end of the sleeve, one end of the scraper away from the sleeve is slidably connected to the lower surface of the disc, a tooth pattern is provided at the lower end of the sleeve, the sleeve is meshed and connected to the rack plate, and the rack plate is slidably connected to the upper surface of the disc.

[0008] Preferably, the cleaning component also includes a limiting rod and a movable plate, the movable plate is slidably connected to the connecting cavity, the limiting rod is fixedly connected to one end of the movable plate, and the end of the rack plate away from the sleeve is slidably connected to the limiting rod.

[0009] Preferably, a spring is fixedly connected between the movable plate and the communicating cavity.

[0010] Preferably, a through hole is provided on the movable plate, and a ring is fixedly connected to one end of the movable plate away from the limiting rod.

[0012] Preferably, bubble levels are installed on both sides of the upper surface of the bracket.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Loosen the moving plate, and the moving plate returns to its original position under the tension of the spring. At this time, the through hole on the moving plate is misaligned with the connecting cavity. The moving plate can close the connecting cavity, so that the other parts in the multiple cylinders no longer flow into each other, so that the bracket can be quickly adjusted to the level. Then, turn the nut to move the vertical rod downward, and the concrete elevation and flatness can be judged by adjusting the disc up and down and contacting the concrete surface.

[0015] After testing the concrete elevation and flatness, if the concrete adheres to the lower surface of the disc, by pulling the movable plate back and forth, the movable plate can drive the rack plate to move back and forth through the limit rod, and the rack plate can drive the sleeve and the scraper to rotate. The scraper can scrape the concrete on the lower surface of the disc to ensure the cleanliness of the disc.

[0016] It is easy to understand, convenient for industrialized production, and simple to explain to workers. It solves the problem of elevation control during the pouring of floor concrete from the source. On the one hand, it greatly reduces the work intensity of workers and speeds up the progress of on-site construction. BRIEF DESCRIPTION OF THE DRAWINGS
