Therefore, the use of various instruments is indispensable in the pouring process of building concrete slabs. Among them, the precise measurement instrument of the thickness of the concrete slab after pouring is particularly important.

[0003] An existing patent (publication number: CN210952632U) discloses a tool for measuring the thickness of poured concrete. The tool uses a movable panel that moves up and down via a threaded straight rod secured with a nut. The rod is inserted into the concrete, and the corresponding marking on the rod indicates the poured concrete thickness. This tool is simple in structure, easy to operate, reusable, and minimizes deviations in poured concrete thickness. However, this technical solution still has shortcomings, as detailed below:

However, this method of measuring the contact between the rod and the concrete makes it difficult to determine the flatness of the concrete top surface and to measure both the width and height of the concrete simultaneously. Therefore, we propose a concrete pouring measurement device to address these issues. Utility Model Content

[0033] The following is combined with Figure 1-4 The utility model is described in further detail.

[0034] Example 1, refer to Figure 1-4 In this embodiment, in order to solve the problem that the existing method of inserting a rod into concrete and observing the markings on the upper side of the rod to determine the thickness of the concrete pouring, but the method of measuring by contact between the rod and the concrete is difficult to determine the flatness of the top surface of the concrete and it is also difficult to measure the width and height of the concrete at the same time, the utility model discloses a concrete pouring measuring device.

[0035] It includes a placement plate 1, a moving frame 2 is fixedly provided on the side of the placement plate 1, a moving block 3 is slidingly provided inside the moving frame 2, a motor 4 is fixedly provided on the upper side of the moving frame 2, the bottom end of the rotating shaft of the motor 4 extends to the inside of the moving frame 2 and is rotatably provided with a threaded rod 5, the bottom end of the threaded rod 5 passes through the lower side of the moving frame 2 and is rotatably matched with the bottom of the inner wall of the moving frame 2, two connecting blocks 6 are fixedly provided on the rear side of the moving frame 2, and a measuring bar 7 is rotatably provided on the opposite side of the two connecting blocks 6.

[0036] The measuring bar 7 includes a rotating bar 701, the front and rear ends of the rotating bar 701 extend to the front and rear sides of the two connecting blocks 6 respectively and are fixed with a limit plate 702. Two slots 703 are provided on the side of the limit plate 702. A pointer 704 is fixed on the front side of the front limit plate 702. A measuring plate 706 is fixed on the side of the rotating bar 701, and the height of the measured concrete can be easily viewed through the pointer 704.

[0037] The cross-sectional shape of the moving block 3 and the internal shape of the moving frame 2 are both cross-shaped. The cross-shaped moving block 3 can slide stably inside the cross-shaped moving frame 2 .

[0038] A scale 705 is provided on the upper side of the measuring bar 7 and the rear side of the moving frame 2 , and the sides of the measuring bar 7 and the moving frame 2 are rounded, so that the data of the concrete measurement can be recorded conveniently through the scale 705 .

[0039] The specific working principle is: first, the measuring plate 706 is deflected to be perpendicular to the moving frame 2, and the motor 4 drives the threaded rod 5 to rotate, so that the threaded rod slides the moving block 3 upward to an appropriate height, and then the concrete pouring measuring device is moved to the outside of the placement frame for pouring concrete, and then the motor 4 and the threaded rod 5 drive the moving block 3 and the measuring plate 706 to move downward, so that the bottom of the measuring plate 706 contacts the upper surface of the concrete, and at the same time, the moving block 3 drives the pointer 704 to stop moving. At this time, the width of the concrete can be measured by the measuring plate 706, and the height of the concrete can be measured by the pointer 704, which makes it more convenient to measure the height and width of the concrete.

[0040] Example 2, refer to Figure 1-4 In order to solve the problem that the existing concrete pouring device is inconvenient to store when it is idle, in this embodiment, based on the same concept as the above-mentioned embodiment 1, the concrete pouring measuring device further includes:

[0041] A movable frame 2 is fixedly provided on the side of the placement plate 1, and two connecting blocks 6 are fixedly provided on the rear side of the movable frame 2. A measuring bar 7 is rotatably provided on the opposite side of the two connecting blocks 6. An L-shaped groove 8 is provided on the top of the two connecting blocks 6, and a clamp 9 is slidingly provided inside the two L-shaped grooves 8.

[0042] The clamp 9 includes two L-shaped plates 901, which are respectively slidably arranged inside the two L-shaped grooves 8. The tops of the two horizontal plates of the two L-shaped plates 901 are fixed with compression springs 902. The tops of the compression springs 902 are fixedly matched with the upper side of the inner wall of the horizontal groove of the L-shaped groove 8, and the C-shaped bar 903 is conveniently driven to move upward through the L-shaped plate 901.

[0043] The vertical plate of the L-shaped plate 901 extends to the upper side of the inner wall of the L-shaped groove 8. A C-shaped bar 903 is fixed on the top of the vertical plates of the two L-shaped plates 901. The side surfaces of the vertical bars of the C-shaped bar 903 slide with the inside of the slot 703. By moving the vertical bars of the C-shaped bar 903 to the inside of different slots 703, the measuring plate 706 can be easily unfolded or folded.

[0044] There are four slots 703, and the four slots 703 are grouped into two and are respectively opened on the upper side of the two limit plates 702 and the front side of the two limit plates 702. When the vertical bar of the C-shaped bar 903 is inserted into the interior of the upper side slot 703, the measuring plate 706 and the moving frame 2 can be in a vertical plane. When the vertical bar of the C-shaped bar 903 is inserted into the interior of the front side slot 703, the measuring plate 706 and the moving frame 2 can be in a parallel plane.

[0045] The specific working principle is: by moving the C-shaped bar 903 upward, the two vertical bars of the C-shaped bar 903 move out from the inside of the slot 703, and at the same time, the C-shaped bar 903 drives the two L-shaped plates 901 to move upward, squeezing the compression spring 902, and then releasing the fixed state of the measuring bar 7, and then deflecting the measuring bar 7 downward, so that the measuring bar drives the rotating bar 701 and the two limit plates 702 to deflect downward, so that the two front slots 703 are deflected to the upper side. At this time, the side surface of the measuring bar 7 is parallel to the moving frame 2, and then the C-shaped bar 903 is relaxed, so that the C-shaped bar 903 and the L-shaped plate 901 move downward by the rebound force of the compression spring 902. At this time, the vertical bar of the C-shaped bar 903 moves to the inside of the slot 703, and the folded concrete pouring measuring device can be quickly stored.

[0046] Example 3, refer to Figure 1-4 Based on the same concept as the first embodiment, the concrete pouring measurement device further includes:

[0047] A movable frame 2 is fixedly provided on the side of the placement plate 1. The placement plate 1 is in the shape of a right-angled trapezoid. A movable wheel 201 is rotatably provided on the rear side of the bottom of the movable frame 2. The movable wheel 201 facilitates the movement of the folded concrete pouring device.

[0048] The specific working principle is: by deflecting the measuring plate 706 to be parallel to the moving frame 2, by tilting the placement plate 1, and making the bottom of the moving wheel 201 contact the ground, the concrete pouring measuring device can be moved to a suitable position, thereby reducing the friction between the concrete pouring measuring device and the ground when moving.

[0049] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention.
