[0002] During building construction and interior and exterior decoration, there are some concrete columns with curved surfaces. The outer wall of these concrete columns is curved, and in steel structure construction, the pre-embedded straight steel plates cannot fit into the curved concrete columns.

[0003] Therefore, a bending device for curved cylindrical steel plates is proposed. Summary of the Invention

[0004] This utility model provides a bending device for arc-shaped cylindrical steel plates, the purpose of which is to solve the problems mentioned above.

[0005] This utility model embodiment provides an arc-shaped cylindrical steel plate bending device, including four detachable temporary fixing plates; a longitudinal position adjustment assembly disposed on the detachable temporary fixing plates; the longitudinal position adjustment assembly includes: a vertical plate disposed between two of the detachable temporary fixing plates in the vertical direction; a screw rod one screwed to the center position of one side outer wall of the vertical plate; a movable plate rotating at one end of the screw rod one; a transverse bending assembly disposed on the movable plate; the transverse bending assembly includes: a screw rod two screwed to the center position of one side outer wall of the movable plate; a pressure seat rotating at one end of the screw rod two; a spring disposed on the inner side wall of the pressure seat; a pressure roller frame disposed at one end of the spring; and a pressure roller rotating on the inner side wall of the pressure roller frame.

[0006] Furthermore, a winch is provided at the other end of the first screw, and a winch is provided at the other end of the second screw.

[0007] Furthermore, two limiting rods are symmetrically arranged on the outer wall of the pressure seat on the side away from the pressure roller, and both limiting rods pass through the moving plate.

[0008] Furthermore, concrete columns are provided on the inner side of the four detachable temporary fixing plates. An arc-shaped surface is provided on one side of the outer wall of the concrete column, and a pre-embedded straight steel plate is provided on one side of the concrete column. A post-anchored steel plate is provided on the outer wall of the concrete column, and the post-anchored steel plate is fixedly connected to the detachable temporary fixing plate.

[0009] Furthermore, the detachable temporary fixing plate has an L-shaped cross-section, and the detachable temporary fixing plate and the movable plate are slidably connected.

[0010] By adopting the above technical solution, the sliding connection is used to limit the movement trajectory of the moving plate, ensuring that the moving plate moves in a straight line along the detachable temporary fixing plate.

[0011] Furthermore, a portion of the pressure roller protrudes from the outer wall of the pressure roller frame;

[0012] By adopting the above technical solution, the pressure roller can squeeze the pre-embedded straight steel plate, avoiding interference caused by the pre-embedded straight steel plate contacting the pre-embedded straight steel plate first.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a pressure roller with pushing force to rotate along a pre-embedded straight steel plate from the inside out. This allows the pre-embedded straight steel plate to be deformed under pressure and gradually adhere to the arc-shaped surface of the concrete column, ensuring a full and tight fit. By utilizing the rotational characteristics of the pressure roller, it is not only convenient to change the horizontal position during the bending process, but also to reduce wear on the pre-embedded straight steel plate.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Reference Figure 1-4 This utility model embodiment proposes an arc-shaped cylindrical steel plate bending device, including four detachable temporary fixing plates 1. A vertical plate 21 of the longitudinal position adjustment component 2 is provided between every two of the four detachable temporary fixing plates 1. A screw rod 22 is threadedly connected to the center of one side outer wall of the vertical plate 21. A winch 23 is provided at one end of the screw rod 22, and a movable plate 24 is rotatably connected to the other end of the screw rod 22. The cross-section of the detachable temporary fixing plate 1 is an L-shaped structure, and the detachable temporary fixing plate 1 and the movable plate 24 are slidably connected. The sliding connection realizes the limitation of the movement trajectory of the movable plate 24, ensuring that the movable plate 24 moves in a straight line along the detachable temporary fixing plate 1.

[0024] A screw 31 from the transverse bending assembly 3 is threadedly connected to the center of one side outer wall of the movable plate 24. One end of the screw 31 is rotatably connected to the pressure seat 32, and the other end of the screw 31 is provided with a winch 33. Two limiting rods 34 are symmetrically arranged on one side outer wall of the pressure seat 32. Both limiting rods 34 pass through the movable plate 24. A spring 35 is embedded in the other side outer wall of the pressure seat 32. A pressure roller frame 36 is provided at one end of the spring 35. A pressure roller 37 is rotatably connected to the inner side wall of the pressure roller frame 36. A part of the pressure roller 37 protrudes from the outer side wall of the pressure roller frame 36, which allows the pressure roller 37 to squeeze the pre-embedded straight steel plate 4, avoiding interference caused by the pre-embedded straight steel plate 4 contacting the pre-embedded straight steel plate 4 before it.

[0025] Concrete columns 5 are installed on the inner side of four detachable temporary fixing plates 1. An arc-shaped surface is provided on one side of the outer wall of the concrete column 5, and a pre-embedded straight steel plate 4 is provided on one side of the concrete column 5. A post-anchored steel plate 6 is provided on the outer wall of the concrete column 5. The post-anchored steel plate 6 and the detachable temporary fixing plates 1 are fixedly connected.

[0026] The specific implementation method is as follows: When the pre-embedded straight steel plate 4 is attached to the outer wall of the concrete column 5, the detachable temporary fixing plate 1 is first fixed on the post-anchored steel plate 6, and the four detachable temporary fixing plates 1 are used to form two sets of pressure structures, and the pre-embedded straight steel plate 4 is lifted on one side of the concrete column 5.

[0027] First, rotate the winch 23. The winch 23 drives the screw 22 to rotate. Through the screw connection between the screw 22 and the vertical plate 21, and the sliding connection between the movable plate 24 and the detachable temporary fixing plate 1, the screw 22 pushes the movable plate 24 to move linearly and pushes the movable plate 24 to the middle position of the pre-embedded flat steel plate 4.

[0028] Then, the winch 2 33 is rotated, which drives the screw 2 31 to rotate. Through the screw 2 31 and the moving plate 24, and the linear guide limit formed by the limit rod 34 passing through the moving plate 24, the screw 2 31 pushes the pressure seat 32 to move towards the pre-embedded straight steel plate 4, and makes the pressure roller 37 contact the pre-embedded straight steel plate 4 and squeeze it to stick to the outer wall of the concrete column 5. At this time, there is a large gap between the pre-embedded straight steel plate 4 and the arc surface of the concrete column 5, and the pre-embedded straight steel plate 4 cannot stick to the concrete column 5.

[0029] Finally, continue rotating winch 23. Since the pressure roller 37 is restricted in position and cannot move, the pressure seat 32 continues to move towards the pre-embedded straight steel plate 4. As the pressure seat 32 moves, the spring 35 between the pressure seat 32 and the pressure roller frame 36 is gradually compressed. The compression potential energy of the spring 35 becomes larger and larger. Then, rotate winch 23 to control the moving plate 24 to move towards the edge of the pre-embedded straight steel plate 4. The transverse bending component 3 on the moving plate 24 moves synchronously. Under the action of the reset deformation force of the spring 35, the pressure roller 37 squeezes the pre-embedded straight steel plate 4 to deform and fit against the arc surface of the concrete column 5. During this period, pressure can be applied to the pressure seat 32 again to ensure that the spring 35 has sufficient deformation force to push the pre-embedded straight steel plate 4 to deform and bend.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
