Description

Technical Field

[0001] This application relates to the technical field of concrete construction, and particularly relates to a concrete thickness detection device. Background Art

[0002] Concrete and asphalt pavements are usually built in municipal roads and rural roads. Their paving thickness is one of the key factors affecting pavement quality. Generally, the paving thickness is detected after paving and before coagulation to ensure the pavement quality after final shaping.

[0003] The patent document with the publication number CN202255217U discloses a concrete thickness detection device, which includes a measuring rod with size scales. A conical probe is provided at the lower end of the measuring rod. A sliding sleeve connected by several hollow cylinders is sleeved on the conical measuring rod. A tray is provided at the bottom of the sliding sleeve, and the sliding sleeve can slide up and down along the measuring rod. When using this concrete thickness detection device, first insert the conical probe at the lower end of the measuring rod into the bottom of the concrete layer. In this way, the tray is supported by the concrete, and the tray drives the sliding sleeve to slide upward. The distance that the sliding sleeve slides upward is also the thickness of the concrete, which has certain positive significance. However, when performing detection, this type of detection device needs to be inserted into the interior of the concrete, which will inevitably cause certain damage to the concrete that is about to take shape and have a certain impact on subsequent construction.

[0021] The present application will now be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, so they only show the components related to the present application.

[0022] As Figures 1-5 shown, a concrete thickness detection device includes a pull rope and two sets of support frames 1 arranged at intervals. A sliding plate 12 is horizontally slidably provided on the support frame 1. A first benchmark 13 is vertically provided at one end of the sliding plate 12 between the two support frames 1, and scales are provided on the first benchmark 13. A sliding rod 2 is provided between the two support frames 1, and a second benchmark 4 is vertically provided on the sliding rod 2, and scales are provided on the second benchmark 4. One end of the pull rope is connected to one of the support frames 1, and the other end is slidably arranged on the other support frame 1. The tops of the second benchmarks 4 are sleeved in the pull rope.

[0023] The two support frames 1 are in a frame structure and are respectively arranged on both sides of the concrete road surface during use. In other embodiments, rollers can be provided at the bottom of the support frame 1 to facilitate the movement of the support frame 1.

[0024] The first benchmark 13 can be as close as possible to the side wall of the road surface under the action of the sliding plate 12. The first benchmark 13 is mainly used to measure the height of both sides of the road surface and the nominal height. The nominal height is the length of the first benchmark 13 below the sliding plate 12.

[0025] The second benchmark 4 is used to measure the height distance from each position in the middle of the road surface to the sliding plate 12. The actual thickness of the concrete is the nominal height minus the vertical height from the bottom of the second benchmark 4 to the sliding plate 12.

[0026] During measurement, loosen the pull rope, and the second benchmark 4 moves downward under its own gravity until it abuts against the road surface. After the measurement is completed, tighten the pull rope to lift the second benchmark 4 upward.

[0027] Under the action of the first benchmark 13 and the second benchmark 4, through difference calculation, the concrete paving thickness at different positions on the road surface can be obtained. Compared with the traditional device that needs to be inserted into the concrete layer for detection, the present application can avoid damaging the concrete layer to ensure normal subsequent construction.

[0028] In some further embodiments, the support frame 1 includes a connecting plate 10, and a sliding groove is provided on the connecting plate 10. The sliding plate 12 is slidably arranged in the sliding groove.

[0029] The sliding groove runs through the connecting plate 10 and extends in the horizontal direction.

[0030] In some further embodiments, a first sliding hole is provided on the sliding plate 12, and the first marking rod 13 is movably arranged in the first sliding hole; a threaded hole is provided on the sliding plate 12, the threaded hole is communicated with the first sliding hole, and a tightening bolt 120 is screwed into the threaded hole.

[0031] The first sliding hole is disposed on one end of the sliding plate 12 on one of the supporting frames 1 facing the other supporting frame 1 .

[0032] It should be noted that the fastening bolt 120 is mainly used to position the first marking rod 13 when not in use. During actual use, the bottom of the first marking rod 13 is usually in contact with the ground on which the road is paved.

[0033] In some further embodiments, the support frame 1 includes a sliding seat 11, the sliding seat 11 is located above the connecting plate 10, a second sliding hole is provided on the top of the sliding seat 11, and the sliding rod 2 is arranged in the second sliding hole to prevent axial sliding.

[0034] Since the widths of the roads are all different, the sliding rod 2 is set to slide to meet the use requirements under different road widths.

[0035] In some further embodiments, the sliding rod 2 is provided with scales.

[0036] A scale is also provided on the sliding rod 2 so that the staff can record the specific thickness at a distance from the road surface, which further facilitates the subsequent remedial construction.

[0037] In some further embodiments, a third sliding hole is provided on the sliding rod 2, and the second mark rod 4 is slidably set in the third sliding hole; the number of the second mark rods 4 and the third sliding holes is relative and multiple, and the multiple second mark rods 4 are axially spaced along the sliding rod 2.

[0038] There are a plurality of second marking rods 4, and preferably five of them in this embodiment, so as to measure the thickness of the entire road surface.

[0039] In some further embodiments, it also includes a guide sleeve 3, which is slidably arranged between the two support frames 1; the guide sleeve 3 is located directly above the sliding rod 2, and two connecting holes 30 are provided on the guide sleeve 3 corresponding to the third sliding hole, the pull rope is passed through the guide sleeve 3, and the part corresponding to the third sliding hole is located outside the guide sleeve 3 through the two connecting holes 30.

[0040] A connecting ring 40 is provided at the top of the second marking pole 4 , and the pull rope passes through the connecting ring 40 to be connected to the second marking pole 4 .

[0041] The guide sleeve 3 is mainly used to prevent the pull rope from being disturbed by the outside, wherein the pull rope can pass through two connection holes 30 located outside the guide sleeve 3 to be connected to the corresponding second marking rod 4.

[0042] The bottoms of the first reference rod 13 and the second reference rod 4 are conical to reduce the risk of being disturbed during contact with the road surface or the ground.

[0043] The zero scales on the first reference rod 13 and the second reference rod 4 are both located at the lower ends.

[0044] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
