However, during the concrete pouring operation, it is necessary to limit the position of the reinforcing cage. In the process of limiting the position of the reinforcing cage in the existing technology, the inventor discovered the following problems.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0032] like Figure 1 and Figure 2 As shown, a positioning auxiliary structure, wherein:

[0033] Includes a limiting device, which includes multiple first limiting plates 15, expansion plates 21 and multiple second limiting plates 34;

[0034] It includes an expansion device, which is disposed above a plurality of first limiting plates 15 and a plurality of second limiting plates 34. The expansion device includes a rotating disk 16 and a plurality of pressing rods 26.

[0035] It is worth noting that the casing 10, hollow support column 11 and fixing ring 12 have all been disclosed in a positioning structure and pile foundation pouring auxiliary device (202022414586.X), and will not be described in detail here.

[0036] In practical use, the limiting device can limit the hollow support column 11 through the operation of the first limiting plate 15 and the second limiting plate 34, which facilitates the pouring operation by the workers. The expansion device can handle hollow support columns 11 of different specifications and positions through the rotating plate 16 and multiple pressing rods 26, and has a wide range of applications.

[0037] In summary, by setting up a limiting device and an expansion device, the limiting device can limit multiple hollow support columns 11, making it convenient for workers to carry out pouring operations. The expansion device can limit hollow support columns 11 of different specifications and positions, expanding the scope of application. Compared with existing technologies, it has the characteristics of being easy to use and having a simple structure.

[0038] like Figure 3 , Figure 4 and Figure 6 As shown, the limiting device also includes a bottom rod 13, the top wall of the bottom rod 13 is hollow, a first threaded rod 14 is threadedly connected inside the cavity of the bottom rod 13, a fixing block 31 is fixedly installed on the top wall of the first threaded rod 14, multiple drive motors 32 are fixedly installed in a ring array on the side wall of the fixing block 31, and a second bolt 33 is fixedly installed at the output end of each of the multiple fixing blocks 31.

[0039] Multiple expansion plates 21 are disposed on the side wall of the fixing block 31. Multiple expansion plates 21 are inverted n-shaped. A threaded hole 22 is opened on the side wall of multiple expansion plates 21 near the fixing block 31. Multiple second bolts 33 are threadedly connected to the corresponding threaded holes 22. A connecting rod 23 is fixedly installed at the ends of multiple expansion plates 21 that are far apart from each other.

[0040] Multiple first limiting plates 15 and multiple second limiting plates 34 are arranged in a ring array on one side away from each other of multiple threaded holes 22. Two connecting blocks 19 are fixedly installed on the bottom wall of each of the first limiting plates 15 and the second limiting plates 34. A rubber block 20 is rotatably installed between the two connecting blocks 19. A first driving block 17 is fixedly installed at both ends of the top wall of the first limiting plate 15 and at the middle position of the top wall of the second limiting plate 34.

[0041] The two sets of first drive blocks 17 are arranged in an inclined and staggered manner. The corresponding side walls of both sets of first drive blocks 17 are hollowed out. The connecting rod 23 is located inside the cavities of the two sets of first drive blocks 17. A second drive block 18 is fixedly installed on the top wall of each set of first drive blocks 17. The side walls of the two sets of second drive blocks 18 that are close to each other are inclined from top to bottom and from far to near. The drive motor 32 is electrically connected to the power supply and switch.

[0042] In practical use, the first limiting plate 15 and the first annular groove 24 will be limited during operation. The specific limiting method will be discussed below. When the operator rotates the first threaded rod 14, it can move up and down through its threaded connection with the bottom rod 13. This not only allows the structure to move to different positions but also adjusts the height. When the output ends of the multiple drive motors 32 rotate, they can drive the second bolt 33 to rotate. The rotation of the second bolt 33 can then drive the expansion plate 21 to move through the threaded hole 22. The movement of the expansion plate 21 can... The connecting rod 23 is moved so that the connecting rod 23 can move the first limiting plate 15 and the second limiting plate 34 through multiple 7, thereby limiting the hollow support column 11 of different specifications or positions. When the first limiting plate 15 and the first limiting plate 17 rotate away from each other at the bottom of the hollow part of the first driving block 17, the connecting block 19 can drive the rubber block 20 to rotate, and the rubber block 20 plays a limiting role. The specific limiting method and the specific rotation method of the first limiting plate 15 and the second limiting plate 34 will be discussed below.

[0043] In summary, by setting up an expansion plate 21, a threaded hole 22, a connecting rod 23, a first driving block 17, a second driving block 18, a connecting block 19, a rubber block 20, an expansion plate 21, a second limiting plate 34, a first limiting plate 15, a bottom rod 13, a first threaded rod 14, a drive motor 32, a fixing block 31, and a second bolt 33, the rotation of multiple drive motors 32 can move multiple first limiting plates 15 and multiple second limiting plates 34 to accommodate hollow support columns 11 of different specifications and positions. The first limiting plate 15 and the first annular groove 24 are rotated to achieve limiting, which is convenient to use and has a simple structure.

[0044] like Figure 3 and Figure 5 As shown, a first threaded rod 14 is also installed on the top wall of the fixed block 31. The rotating disk 16 is threadedly connected to the first threaded rod 14. A first annular groove 24 is opened on the side wall of the rotating disk 16. A second annular groove 30 is opened on both the top and bottom walls of the cavity of the first annular groove 24.

[0045] Multiple pressing rods 26 are arranged in a ring array on the side wall of the rotating disk 16. Each pressing rod 26 is located between two corresponding sets of second driving blocks 18. A first telescopic rod 27 is fixedly installed at both ends of each pressing rod 26. The ends of the two first telescopic rods 27 near the rotating disk 16 are hollowed out. A second telescopic rod 28 is movably installed in the cavity of each of the two first telescopic rods 27. A connecting plate 29 is fixedly installed on the upper and lower side walls of the ends of the two second telescopic rods 28 near the rotating disk 16. The two connecting plates 29 are movably connected to the cavities of the corresponding second annular grooves 30.

[0046] In practical use, when the second drive block 18 moves along with the first drive block 17, it also drives the clamping pressing rod 26 to move. The first telescopic rod 27 and the second telescopic rod 28 can extend and retract to cooperate with its movement. When the rotating disk 16 rotates, it can move up and down through the threaded connection with the first threaded rod 14, thereby raising the first annular groove 24 and the second annular groove 30 to drive the connecting plate 29 to move up and down. The connecting plate 29 can drive the second telescopic rod 28 to move up and down, and the up and down movement of the second telescopic rod 28 can drive the pressing rod 26 to move up and down. In this way, the inclined surfaces of the two sets of second drive blocks 18 drive the first limiting plate 15 and the second limiting plate 34 to rotate around the connecting rod 23, thereby achieving the function of limiting the position.

[0047] In summary, by setting up a rotating disk 16, a first annular groove 24, a second annular groove 30, a connecting plate 29, a second telescopic rod 28, a pressing rod 26, and a first telescopic rod 27, the first limiting plate 15 and the second limiting plate 34 can be rotated by the operator rotating the rotating disk 16 to achieve the limiting function. The movement of the first limiting plate 15 and the second limiting plate 34 can be responded to by the extension and retraction of the first telescopic rod 27 and the second telescopic rod 28. It is convenient to use and has a simple structure.

[0048] like Figure 1 and Figure 2 As shown, a pouring device for building construction includes a positioning auxiliary structure and a protective casing 10 as described above. Multiple hollow support columns 11 are provided inside the cavity of the protective casing 10. The top walls of the multiple hollow support columns 11 are all hollow. Two fixing rings 12 are installed on the side walls of the multiple hollow support columns 11 that are far apart from each other. The bottom rod 13 can be located inside the cavity of the protective casing 10. Multiple first limiting plates 15 and multiple second limiting plates 34 are respectively inserted into the cavities of the corresponding hollow support columns 11.

[0049] In practical use, when the first limiting plate 15 and the second limiting plate 34 are inserted into the cavity of the hollow support column 11, the left and right side walls of the cavity of the hollow support column 11 will limit the first limiting plate 15 and the second limiting plate 34, so that the first limiting plate 15 and the second limiting plate 34 will not be driven by the drive motor 32 to rotate. When the first limiting plate 15 and the first annular groove 24 rotate to make the rubber block 20 fit against the inner wall of the cavity of the hollow support column 11, the material of the rubber block 20 can play a limiting role.

[0050] In summary, by setting up a hollow support column 11, a rubber block 20, a first limiting plate 15, and a second limiting plate 34, the first limiting plate 15 and the second limiting plate 34 can be inserted into the cavity of the hollow support column 11, and then the rubber block 20 can be rotated to fit against the inner wall of the hollow support column 11 to achieve the limiting function. It is convenient to use and has a simple structure.
