Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a measuring device for the pouring thickness of concrete. Background Art

[0002] Concrete is a main component of construction engineering. The thickness of concrete pouring during the construction process is a very important quality control process. During the pouring process, it is necessary to continuously measure to ensure that the pouring thickness of concrete meets the requirements of the design drawings. At present, in most construction projects during the concrete pouring process, multiple concrete thickness control points are pre-piled on the formwork to be poured or marking lines are made on the formwork to control the size of the concrete pouring thickness. Such methods are time-consuming and laborious, and the size control is inaccurate. To solve the above problems, measuring devices for the pouring thickness of concrete have been more and more widely used.

[0003] The patent with the publication number CN208872217U discloses a tool suitable for measuring the pouring thickness of concrete, including a scale, a horizontal plate, and a spirit level. However, this tool has high precision requirements, large weight, and high manufacturing difficulty. The measurement scale line at the bottom is easily contaminated by concrete, making it inconvenient to see the size of the concrete pouring thickness. The horizontal plate moves up and down continuously with the thickness of the already poured concrete, and ordinary operators cannot accurately master the size of the pouring surface thickness.

[0005] Technical Solution: To solve the above problems, the utility model adopts a measuring device for the pouring thickness of concrete, including a vertical rod and a measuring rod installed in the vertical rod. The vertical rod is a hollow tube with a closed top and an open bottom. A section of scale is provided on the side of the upper part of the vertical rod, and a slot is provided on the side of the vertical rod where this section of scale is located. A bottom plate is provided at the bottom of the vertical rod, and a through hole is opened on the bottom plate. The measuring rod passes through this through hole. A dial rod is provided on the side of the measuring rod, and a scale pointer is provided on the dial rod. The dial rod moves up and down in the slot to drive the measuring rod to expand and contract relative to the vertical rod.

[0006] Further, the dial rod is a bolt, and a first nut and a second nut are provided on the bolt. The first nut is located between the second nut and the measuring rod, and the scale pointer is installed on the second nut.

[0007] Further, the vertical rod and the measuring rod are coaxially arranged, and the axis of the dial rod is perpendicular to the axis of the measuring rod.

[0008] Further, the vertical rod, the measuring rod, the dial rod, and the scale pointer are all made of stainless steel, and the bottom plate is made of steel plate.

[0009] Further, the scale is a tape measure strip or a double-sided sticker with graduations.

[0010] Further, the longitudinal section of the slot is U-shaped.

[0011] Further, a lifting ring is provided at the top of the vertical rod.

[0012] Beneficial effects: Compared with the prior art, the remarkable advantage of the present utility model is that the scale is arranged on the upper part of the vertical rod, which is not easily contaminated by concrete, the scale reading is clearer, and the structure is simple, the operation is convenient, and the versatility is strong.

[0015] As Figure 1 and Figure 2 shown, a concrete pouring thickness measuring instrument in this embodiment includes a vertical rod 1 and a measuring rod 2, and the vertical rod 1 and the measuring rod 2 are coaxially arranged. The vertical rod 1 is a hollow tubular with a closed top and an open bottom. A lifting ring 9 is provided at the top of the vertical rod 1 for easy suspension. A bottom plate 4 is provided at the bottom of the vertical rod 1, and a through hole is opened in the center of the bottom plate 4. The measuring rod 2 is installed in the vertical rod 1 through this through hole. A section of scale 3 is provided on the side of the upper part of the vertical rod 1, and the scale 3 is a tape measure strip or a double-sided sticker with graduations. A slot 11 is provided on the side of the vertical rod 1 where this section of scale 3 is located, and the longitudinal section of the slot 11 is U-shaped.

[0016] A dial rod 5 is provided on the side of the measuring rod 2.
