The utility model is mounted on the steel formwork by supporting rails provided in four directions of the calibration plate, and the positioning is adjusted by the positioning piece provided on the support rails to meet the use requirements of cylindrical steel formworks of different sizes; the remote control lifting and lowering of the detection plumb is realized by the automatic rope winding mechanism provided on the calibration plate, which reduces manual input and improves detection efficiency.

[0004] However, the cylindrical steel template calibration device in the above technology still has the following problems:

[0005] When calibrating the cylindrical steel formwork, it is impossible to ensure that the plumb bob is located at the center axis of the cylindrical steel formwork. The plumb bob is suspended on the cylindrical steel formwork through the support rail. The plumb bob that is not located at the center axis of the cylindrical steel formwork exerts uneven downward pressure on the support rail, resulting in different degrees of bending in different support rails, which in turn causes the entire calibration device to tilt, making it impossible to accurately calibrate the cylindrical steel formwork.

[0021] See also Figure 1 - Figure 4 A calibration device for a cylindrical steel formwork comprises a steel formwork body 1 and a plumb plate 2, wherein a plurality of support rods 3 are fixedly connected to the outer wall of the plumb plate 2, wherein the plurality of support rods 3 are slidably connected to the upper surface of the steel formwork body 1, and a plurality of support rods 3 are penetrated by a sliding groove 301 on the side away from the steel formwork body 1, and an inner clamping plate 4 is slidably connected in the plurality of sliding grooves 301, and the plurality of inner clamping plates 4 are abutted against the inner wall of the steel formwork body 1, and an adjustment component is simultaneously connected to the side away from the steel formwork body 1.

[0022] like Figure 1 - Figure 4 As shown, the cylindrical steel formwork calibration device in the utility model is similar in structure to the existing cylindrical steel formwork calibration device, such as an adjustable cylindrical steel formwork center calibration device disclosed in the patent with publication number CN214364931U. The main improvement of the utility model is that the user can calibrate the center of the steel formwork body 1 more accurately, such as Figures 1 to 4 As shown, when the cylindrical steel formwork calibration device in the utility model is in use, multiple inner clamps 4 are adjusted at the same time through the adjustment assembly. The inner clamps 4 slide back and forth on the support rods 3 through the slide grooves 301, and finally rest against the inner wall of the steel formwork body 1, and cooperate with other inner clamps 4, so that the plumb plate 2 is located at the center of the steel formwork body 1. At this time, the center of the steel formwork body 1 can be calibrated by the plumb bob under the plumb plate 2.

[0023] like Figure 1 - Figure 4As shown, the adjustment assembly includes an adjustment disk 5, a spiral thread 6 and a plurality of adjustment plates 7, the plurality of adjustment plates 7 are respectively fixedly connected to the side of the plurality of inner clamping plates 4 away from the steel template body 1, the side of the plurality of adjustment plates 7 away from the steel template body 1 is provided with a tooth groove 701, the spiral thread 6 is fixedly connected to the side of the adjustment disk 5 close to the steel template body 1, the spiral thread 6 is slidably connected to the plurality of tooth grooves 701, and a rotating member is connected to the center position of the adjustment disk 5 and the center position of the plumb plate 2. The adjustment disk 5 is driven to rotate by the rotating member, and when the adjustment disk 5 rotates, the plurality of inner clamping plates 4 are simultaneously moved outward through the spiral thread 6 and the tooth grooves 701 provided on the plurality of adjustment plates 7, and finally the plurality of inner clamping plates 4 are simultaneously pressed against the inner wall of the steel template body 1, and the plurality of inner clamping plates 4 that are moved at the same time are at an equal distance from the middle plumb plate 2, thereby keeping the plumb plate 2 at the center position of the steel template body 1, so that the center calibration of the steel template body 1 is more accurate.

[0024] like Figure 3 As shown, the rotating member includes a rotating motor 8, a motor fixing groove 201 is provided at the center of the plumb plate 2, the outer wall of the rotating motor 8 is fixedly connected to the inner wall of the motor fixing groove 201, and the output shaft of the rotating motor 8 is fixedly connected to the center of the adjusting disk 5.
