Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Combine the following Figures 1 to 5 A circular prefabricated column reinforcement positioning and adjustment device provided in an embodiment of the utility model is described.

[0029] This embodiment provides a circular prefabricated column reinforcement positioning and adjustment device, such as Figure 1 and Figure 2 As shown, it includes a support frame 2 and a rotating plate 1.

[0030] The support frame 2 is provided with a receiving space for the steel bars of the circular prefabricated column to pass through. The rotating plate 1 is arranged to be rotatable around its center on the support frame 2. The rotating plate 1 is coaxially arranged with the circular prefabricated column and is located above the receiving space. The rotating plate 1 is provided with a plurality of steel bar positioning holes 11 evenly distributed around its center, and the number of the steel bar positioning holes 11 is the same as the number of the steel bars.

[0031] When the utility model is in use, the rotating plate 1 is rotatably arranged on the supporting frame 2, and a plurality of steel bar positioning holes 11 are evenly arranged on the rotating plate 1 in a circular trajectory around the center thereof. During construction, the rotating plate 1 is perpendicular to the vertical steel bars on the circular prefabricated column, and a receiving space for the steel bars on the circular prefabricated column to pass through is provided by the supporting frame 2, so that the steel bars enter the receiving space. The position of the reserved steel bars can be adjusted by rotating the circular steel plate, so that the plurality of steel bar positioning holes 11 respectively correspond to the plurality of steel bars in the receiving space below, and the position of the steel bars below is adjusted by referring to the positions of the steel bar positioning holes 11. Through this device, the accuracy of the installation of the steel bars of the prefabricated column can be accurately controlled, the efficiency of the installation of the circular prefabricated column in the later stage can be improved, and the installation quality can be guaranteed.

[0032] The circular precast column steel bar positioning and adjustment device provided in this embodiment is used for positioning the vertical steel bars of the cylindrical precast column. The above-mentioned turning plate 1 is made according to the dimensions of the precast column reinforcement drawing and is fixed to the steel bars at the top of the precast column. The arrangement of the steel bar positioning holes 11 on the turning plate 1 improves the positioning reference for the steel bars of the circular precast column. The steel bar positioning holes 11 can be used to position and adjust the position of the steel bars, which provides convenience for the subsequent lifting and docking of the precast columns. It is easy to operate and can be used in rotation, thereby improving the construction efficiency of the circular precast columns.

[0033] In this embodiment, Figure 3 As shown, the support frame 2 includes a base and a mounting platform 21 connected to each other, the accommodating space is arranged in the base, and the rotating plate 1 is a circular plate and is rotatably arranged on the mounting platform 21 .

[0034] Specifically, the base includes a bottom plate 23 and columns 22. The bottom plate 23 is provided with a first through hole 3 for the round prefabricated column to pass through. The central axis of the first through hole 3 coincides with the central axis of the rotating plate 1. The area between the first through hole 3 and the rotating plate 1 forms a accommodating space. The columns 22 are evenly distributed around the bottom plate 23. The bottom ends of the columns 22 are connected to the bottom plate 23, and the top ends of the columns 22 are connected to the mounting platform 21.

[0035] In this arrangement, the column 22 is the main vertical supporting part of the support frame 2 and can be made of a steel pipe or a steel plate. It is responsible for bearing the vertical pressure from the upper load. The bottom plate 23 serves as a transverse member connecting the columns 22, which can prevent the columns 22 from being displaced or deformed in the horizontal direction. In addition, the bottom plate 23 is also used to be stably set on a supporting surface such as the end face of a circular prefabricated column, which can increase the contact area with the supporting surface and improve the stability of the support frame 2.

[0036] In this embodiment, the frame-type base composed of the bottom plate 23 and the columns 22 has a simple structure, is light in weight and easy to move, and saves materials and costs compared to a solid base. The bottom plate 23, the columns 22 and the mounting platform 21 can be integrally formed or connected to each other by welding.

[0037] Preferably, the base plate 23 is configured as a square plate to facilitate positioning of the support frame 2. For example, by pre-setting a square positioning line on the support surface, the center of the square is colinear with the center of the circular prefabricated column and the center of the circularly arranged steel bars, and the positioning line is aligned with each side of the base plate 23 to achieve positioning of the support frame 2.

[0038] Furthermore, the first through hole 3 is a circular hole, and the diameter of the first through hole 3 can be set to just allow a plurality of steel bars arranged in a circle on the circular prefabricated column to pass through.

[0039] Preferably, a handle is provided on the upper surface of the rotating plate 1 to facilitate the movement of the rotating plate 1 and the manual rotation of the rotating plate 1 .

[0041] In other embodiments, Figure 5 As shown, the mounting platform 21 is provided with a circular second through hole 4, and a circle of annular mounting grooves 5 are provided on the inner wall surrounding the second through hole 4. The rotating plate 1 is horizontally embedded in the annular mounting groove 5 and can rotate in the annular mounting groove 5 around its central axis, and the central axis of the annular mounting groove 5 coincides with the central axis of the rotating plate 1. In other words, the rotating plate 1 is horizontally arranged in the annular mounting groove 5, and the rotating plate 1 is perpendicular to the vertical steel bars of the circular prefabricated column. By being installed in the annular mounting groove 5, the rotating plate 1 can be restricted from moving upward, so that the rotating plate 1 can stably rotate in the annular mounting groove 5.

[0042] The mounting platform 21 includes a first connecting plate 211, a partition 212, and a second connecting plate 213. The first connecting plate 211 and the second connecting plate 213 are arranged in parallel. The middle parts of the first connecting plate 211 and the second connecting plate 213 are correspondingly provided with second through holes 4. The top end of the column 22 is connected to the bottom surface of the first connecting plate 211. The partition 212 is connected between the first connecting plate 211 and the second connecting plate 213. The space between the first connecting plate 211 and the second connecting plate 213 forms a mounting groove. For example, the partition 212 is a rectangular plate. The middle part of the partition 212 is provided with a circular third through hole. The center of the third through hole is colinear with the center of the second through hole 4, and the diameter of the third through hole is greater than the diameter of the second through hole 4, so that the inner side of the third through hole and the space between the first connecting plate 211 and the second connecting plate 213 together form an annular mounting groove 5.

[0043] Preferably, the first connecting plate 211 and the second connecting plate 213 have the same size.

[0044] In this embodiment, a connection structure is provided between the rotating plate 1 and the mounting groove, and the rotating plate 1 is detachably connected to the mounting groove through the connection structure. Such a configuration facilitates the replacement of the rotating plate 1, and by providing steel bar positioning holes 11 of different diameters and different positions on the rotating plate 1, the rotating plate 1 is adapted to the steel bars of different round prefabricated columns, so as to meet different construction requirements and improve the versatility of the steel bar positioning and adjustment device for round prefabricated columns.

[0045] In a specific embodiment, the connection structure includes an assembly hole 6 and a mounting block 7. A plurality of assembly holes 6 are provided and arranged on the second connection plate 213. The plurality of assembly holes 6 are all connected to the second through hole 4. The mounting blocks 7 are provided on the outer circumferential surface of the rotating plate 1 and a plurality of mounting blocks 7 are provided. The number of mounting blocks 7 and the assembly holes 6 are the same and matched. The mounting blocks 7 are movably connected to the annular mounting groove 5. That is, by one-to-one correspondence between the plurality of mounting blocks 7 of the rotating plate 1 and the assembly holes 6, the mounting blocks 7 are installed into the annular mounting groove 5 below, and the rotating plate 1 is clamped in the annular mounting groove 5 through the mounting blocks 7, so that the rotating plate 1 and the annular mounting groove 5 are rotatably connected.
