[0002] With the continuous development and progress of my country's construction industry and the gradual improvement of public awareness of quality, engineering quality has become a focus of society. In the process of engineering implementation, controlling the thickness of cast-in-place concrete floor slabs is of paramount importance to engineering quality and also a major challenge in construction. Typically, floor slab thickness is controlled by elevation control points on the vertical structural reinforcement, with the reference point usually located 50 centimeters above the structural slab surface. To control the floor slab thickness, the distance between the reference elevation point and the cast-in-place concrete surface must be measured immediately after pouring a section, thereby controlling the slab thickness.

[0003] The above-mentioned conventional methods do not have any control points in the middle of large rooms, making it difficult to accurately control the thickness of large-area floor slabs. In addition, the reference points are usually located on the surface of the structural slab. To control the thickness of the floor slab, the distance between the reference elevation point and the cast-in-place concrete surface needs to be measured immediately after a section is poured. This is not only cumbersome to construct, but also prone to missing measurement points. Summary of the Invention

Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0039] As Figure 1 and 4 shown, the embodiment of the present application provides a telescopic concrete cast-in-place floor thickness control method, comprising the following steps:

[0040] S1, analyzing the construction drawings to obtain a plurality of virtual floor thickness control points in the floor pouring area;

[0041] In one embodiment, the current floor pouring area is analyzed, and the positions of the virtual floor thickness control points in the pouring area are calculated during the rising of the concrete plane according to the area of the pouring area, the amount of poured concrete, the pouring speed, and the flow speed of the concrete.

[0042] In another embodiment, the floor pouring areas of all floors of the current building are analyzed to obtain the virtual floor thickness control points in the floor pouring areas of all floors.

[0043] In the above embodiment, the virtual floor thickness control points are used, which eliminates the positioning and layout steps of the virtual floor thickness control points, and the positions of the virtual floor thickness control points can be quickly obtained and marked, thereby reducing the workload of the construction personnel.

[0044] S2, adjusting the length of the telescopic rod 11 according to the thickness of the poured floor, so that the length of the control rod 1 is lower than the thickness of the poured floor by 4-6 mm;

[0045] S3, planning a path to guide the construction personnel to the virtual floor thickness control point;

[0046] S4, the base 12 of the control rod 1 is welded with the floor steel bars by welding at each thickness control point;

[0047] S5, during the pouring process, after the concrete covers the top plate 13 of the control rod 1, continue pouring 4-6mm, so that the poured concrete reaches the design thickness of the floor, and the control rod 1 does not leak out of the floor surface.

[0048] It should be noted that the control rod 1 is installed at the virtual floor thickness control point to serve as a measurement reference. Different positions of the control rod 1 can display the thickness of the concrete at different positions, so as to adjust the pouring speed and pouring position in time. After setting the length of the control rod 1 and installing it, during the pouring process, the current floor thickness can be known according to the position of the concrete covering the control rod 1. After the concrete covers all the top plates 13 of the control rods, continue pouring 4-6mm, so that the poured concrete reaches the design thickness of the floor.

[0049] As shown in Figure 4 The control rod 1 includes an extension rod 11, a top plate 13 and a base 12 welded at both ends of the extension rod 11. The mounting hole 121 is provided on the base 12, and the position of the control rod 1 is welded and fixed with the floor steel bars by inserting iron nails into the mounting hole 121. The extension rod 11 is composed of two nested steel pipes, and the surface of the extension rod 11 is provided with a fixing hole. After adjusting the length of the extension rod 11, the position of the two steel pipes is fixed by inserting a pin into the fixing hole.

[0050] In one example, the length of the control rod 1 is adjusted: after loosening the pin, according to the thickness of the poured floor, shorten 4-6mm, then insert the pin into the extension rod 11 to fix the length of the control rod 1, and complete the length adjustment.

[0051] In another example, during the pouring process, after the concrete covers the top plate 13 of the control rod 1, continue pouring 4-6mm, so that the poured concrete reaches the design thickness of the floor.

[0052] In the above examples, the concrete can also enter the inside of the extension rod 11 from the fixing hole to fill the inside, so as to facilitate the control rod 1 to form an integral body with the floor after pouring is completed.

[0053] In another example, the base 12 is welded with the floor steel bars.

[0054] In another example, the base 12 is welded with the floor steel bars by inserting iron nails into the mounting hole 121.

[0055] In the above two examples, only the installation method is different, the position where the base 12 is convenient to be directly welded with the floor steel bars can be directly welded, and the position where the base 12 is not convenient to be directly welded with the floor steel bars can be welded with the floor steel bars through the iron nails penetrating the installation holes 121.

[0056] As shown in Figures 2-4 The embodiment of the present application provides a telescopic concrete cast-in-place floor thickness control system, which comprises a positioning system 2, wherein the positioning system 2 comprises a locator 21 and a uwb positioning base station 22, the locator 21 and the uwb positioning base station 22 are respectively in communication connection with a server 3, the server 3 analyzes data sent by the uwb positioning base station 22 and then transmits positioning information and path information of the locator 21 reaching a virtual floor thickness control point to the locator 21 to guide the construction personnel.

After the server 3 analyzes the positioning data sent by the uwb positioning base station 22, the positioning information and the path information of the locator 21 to reach the virtual floor thickness control point are transmitted back to the locator 21, and the position and path of the locator 21 are displayed on the display screen 212.

[0067] In an example, the inspection module 6 collects the image of the control rod 1 captured by the camera 213, and checks whether the control rod 1 is in a vertical state by identifying the control rod 1.

[0068] In another example, the inspection module 6 collects the image of the control rod 1 captured by the camera 213 and the data of the level sensor 217, and judges whether the control rod 1 is in a vertical state by identifying the control rod 1 in the image and combining the data of the level sensor 217 as a reference.
