DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-5 This application is described in further detail.

[0023] The embodiment of the present application discloses a structural column formwork fastening device. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a structural column formwork fastening device includes a connecting plate 1. The inner wall of one end of the connecting plate 1 is slidably connected to the outer surface of one side of the middle part of the limiting rod 7. The middle outer surface of the limiting rod 7 is slidably connected to the middle inner wall of the second sleeve 8. The limiting rod 7 can limit the relative angle of the two connecting plates 1 to prevent the connecting plate 1 from rotating arbitrarily when the inserted rod 3 drives the threaded tube 2 to rotate.

[0024] See also Figure 4 The inner wall of the middle part of the connecting plate 1 is threadedly connected to the outer surface of the middle part of the threaded tube 2. The number of threaded tubes 2 is two. The outer surfaces of the middle parts of the two threaded tubes 2 are respectively threadedly connected to the inner walls of the middle parts of the two connecting plates 1. The two threaded tubes 2 are driven to rotate by the insertion rod 3, so that the two threaded tubes 2 can respectively drive the two connecting plates 1 to move in opposite directions to adjust the distance between the two connecting plates 1. The inner wall of the middle part of the threaded tube 2 is slidably connected to the outer surface of one side of the middle part of the insertion rod 3. The cross section of one end of the insertion rod 3 is an isosceles triangle setting. A limiting groove 14 is provided on one side of the middle part of the rod 3, and the inner wall in the middle part of the limiting groove 14 is slidably connected to the outer surface of one end of the limiting block 12. The isosceles triangle setting of the insertion rod 3 can facilitate the assembly with the threaded tube 2, and the matching of the limiting groove 14 and the limiting block 12 can be completed quickly without carefully adjusting the angle of the insertion rod 3. The middle outer surface of the insertion rod 3 is slidably connected to the middle outer surface of the first sleeve 4, one side of one end of the connecting plate is fixedly connected to one end of the fixing frame 5, and the other end of the fixing frame 5 is fixedly connected to one side of one end of the splint 6.

[0025] See also Figure 4, one end of the threaded tube 2 is fixedly connected to one side of the fixed plate 9, and the other side of the fixed plate 9 is fixedly connected to one end of the telescopic outer tube 10 through the support plate, one end of the inner wall of the telescopic outer tube 10 is fixedly connected to one end of the spring 13, and the other end of the spring 13 is fixedly connected to one end of the telescopic inner rod 11. The setting of the spring 13 can push the limit block 12 to prevent the limit block 12 from sliding out of the limit groove 14 uncontrollably. At the same time, the limit block 12 can be quickly pushed into the limit groove 14, and the inner wall of the other end of the telescopic outer tube 10 is slidably connected to the outer surface of one end of the telescopic inner rod 11. One end of the telescopic inner rod 11 is fixedly connected to one end of the limit block 12, and the outer surface of the other end of the limit block 12 It is set to be tilted, and the tilted outer surface of the other end of the limit block 12 is slidably connected to the outer surface of one side of one end of the insertion rod 3. One side of one end of the insertion rod 3 is set to be tilted. The tilted setting of the outer surface of one end of the limit block 12 can enable the insertion rod 3 to push the limit block 12 to move, so that the insertion rod 3 can move smoothly. The tilted outer surface of one side of one end of the insertion rod 3 can enable the insertion rod 3 to smoothly push the limit block 12 to move while preventing the limit block 12 from continuing to move in the limit groove 14, causing the limit block 12 to detach from the limit groove 14. There are two limit blocks 12, and one end of the two limit blocks 12 is fixedly connected to one end of the two telescopic inner rods 11 respectively, and the two limit blocks 12 are symmetrically set.

[0026] The implementation principle of the structural column formwork fastening device of the present application is as follows: the insertion rod 3, the first sleeve 4, the limit rod 7, and the second sleeve 8 are respectively inserted into the positioning holes opened on the template, the two connecting plates 1 are respectively placed on both sides of the template, and the two threaded tubes 2 are respectively sleeved on the two ends of the insertion rod 3. The inner wall of one end of the connecting plate 1 is sleeved on the outer surface of one end of the limit rod 7, and the connecting plate 1 is pushed to make the threaded tube 2 slide on the outer surface of one side of the middle of the insertion rod 3. When the inclined outer surface of one end of the insertion rod 3 contacts the inclined outer surface of one end of the limit block 12, it pushes the limit block 12 to move, so that the telescopic inner rod 11 is inserted into the telescopic outer tube 10, the spring 13 is squeezed so that the threaded tube 2 can slide smoothly on the insertion rod 3 until the limit block 12 moves to the limit groove 14, and the spring 13 releases the thrust, pushing the limit block 12 to be inserted into the limit groove 14, and rotating the hexagonal bolt rod set at one end of the insertion rod 3, so that the insertion rod 3 drives the two threaded tubes 2 to rotate, and the rotation of the two threaded tubes 2 can drive the two connecting plates 1 to move relative to each other, so that the distance between the two connecting plates 1 is gradually reduced, and then the connecting plate 1 drives the splint 6 to move toward the template, so that the two connecting plates 1 cooperate with the two sets of splints 6 to clamp and fix the two sides of the template.

[0027] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
