Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model provides a technical solution: a device for fixing corrugated pipes embedded in high-strength grouting material for steel formwork columns.

[0030] like Figure 1 and Figure 2 As shown, it includes a first fixing cover 1 and a second fixing cover 2. The second fixing cover 2 is located on one side of the first fixing cover 1. The first fixing cover 1 and the second fixing cover 2 can wrap the upper ends of two adjacent vertical corrugated pipes. The interior of the first fixing cover 1 and the second fixing cover 2 is provided with a rear groove. When placing the first fixing cover 1 and the second fixing cover 2, they can be directly put on the uppermost end of the corrugated pipe.

[0031] To accommodate corrugated pipes of different diameters, an extrusion plate 11 is provided on one side inside the first fixing cover 1 and the second fixing cover 2, which can accommodate corrugated pipes of different diameters. The front end of the extrusion plate 11 passes through the first fixing cover 1 and is provided with a second threaded rod 15. The outside of the second threaded rod 15 is threadedly engaged with the through position of the first fixing cover 1. One end of the second threaded rod 15 is rotatably connected to one end of the extrusion plate 11. Rotating the second threaded rod 15 can fix the first fixing cover 1 at the upper end of the corrugated pipe, thus accommodating corrugated pipes of different diameters.

[0032] To facilitate the transmission of the second threaded rod 15, a second adjusting disc 5 is provided at one end of the second threaded rod 15. The rotation of the second adjusting disc 5 can directly drive the second threaded rod 15 to rotate.

[0033] like Figure 3As shown, in order to accommodate the spacing between two adjacent corrugated pipes, the first fixed cover 1 is slidably wrapped around the outside of the second fixed cover 2; a first threaded rod 14 is transversely provided at the sliding position of the first fixed cover 1 and the second fixed cover 2, the outside of the first threaded rod 14 is threadedly engaged with the inside of the second fixed cover 2, one end of the first threaded rod 14 is rotatably connected to the first fixed cover 1, and the first threaded rod 14 can push the second fixed cover 2 by rotating inside the first fixed cover 1. After pushing the second fixed cover 2, the spacing between the second fixed cover 2 and the first fixed cover 1 can be adjusted.

[0034] To facilitate adjustment of the distance between the first fixed cover 1 and the second fixed cover 2, a second bevel gear 13 is welded to one end of the first threaded rod 14 near the first fixed cover 1. A first bevel gear 12 is provided on one side of the second bevel gear 13, and the outside of the first bevel gear 12 is meshed with the outside of the second bevel gear 13. A first adjusting disc 4 is provided at one end of the first bevel gear 12. The operator holds the first adjusting disc 4 and can drive the second bevel gear 13 to rotate through the first bevel gear 12. The outside of the first bevel gear 12 is embedded in the inside of the first fixed cover 1 and is rotatably connected to the first fixed cover 1.

[0035] An extension piece 6 is welded to one side of the outer wall of the first fixing cover 1 and the second fixing cover 2, and the extension piece 6 is welded and fixed to the outer wall of the first fixing cover 1 and the second fixing cover 2, such as... Figure 4 As shown, an installation groove 7 is provided on one side and one end of the inside of the extension piece 6, and the installation groove 7 passes through and extends to the upper and lower ends of the extension piece 6. The reserved installation groove 7 facilitates the passage of the connecting frame 8 and the fixing of the connecting frame 8.

[0036] like Figure 5 and Figure 6 As shown, a connecting frame 8 is provided through the interior of the mounting groove 7. Another connecting frame is provided at the upper end of one side of the connecting frame 8. The two connecting frames are mirror images of each other. A connecting ring 9 is provided at one end of the exterior of each of the two connecting frames 8. The exterior of the connecting ring 9 is slidably connected to the interior of the connecting frame 8. A threaded wall 10 is provided around the exterior of one of the connecting frames 8 facing the connecting ring 9 inside the other connecting frame 8. The exterior of the threaded wall 10 is threadedly engaged with the interior of the connecting ring 9. The two connecting frames 8 are connected to the other connecting frame 8 through their respective connecting rings 9. The mirror images of the connecting frames 8 pass through the mounting groove 7 and fix the corresponding extension piece 6 of the mounting groove 7.

[0037] To facilitate gripping of a set of first fixed covers 1 and second fixed covers 2, a handle 3 is provided between the first fixed cover 1 and the second fixed cover 2. The handle 3 is welded and fixed to the outer wall of the first fixed cover 1. The handle 3 facilitates gripping, installation and disassembly of the first fixed cover 1 and the second fixed cover 2.

[0038] In embodiment one, during operation, when using the corrugated pipe fixing device to fix the fixing device, the handle 3 is held to move the first fixing cover 1 and the second fixing cover 2. The rotation of the first adjusting disc 4 can drive the second bevel gear 13 to rotate through the first bevel gear 12. The second bevel gear 13 drives the first threaded rod 14 to rotate. The rotation of the first threaded rod 14 can adjust the distance between the first fixing cover 1 and the second fixing cover 2, so that two adjacent corrugated pipes are respectively embedded in the grooves inside the first fixing cover 1 and the second fixing cover 2. Rotating the second adjusting disc 5 pushes the extrusion plate 11, so that the extrusion plate 11 extrudes the corrugated pipe and causes the first fixing cover 1 and the second fixing cover 2 to be inserted into the grooves inside the first fixing cover 1 and the second fixing cover 2. The second fixing cover 2 covers the uppermost end of the bellows. The first fixing cover 1 and the second fixing cover 2 are a group. The first fixing cover 1 and the second fixing cover 2 in the two adjacent groups are brought close to each other by corresponding extension pieces 6. The two connecting brackets 8 are respectively inserted into the mounting grooves 7 inside the two extension pieces 6. One of the connecting brackets 8 rotates at the position of the threaded wall 10 on the outer wall of the other connecting bracket 8 through the connecting ring 9. The rotation of the connecting ring 9 and the threaded wall 10 produce a threaded engagement. The threaded engagement causes the two connecting brackets 8 to move relative to each other, fixing the two extension pieces 6 that are brought close to each other. Fixing the extension pieces 6 fixes the two adjacent groups of first fixing covers 1 and second fixing covers 2.

[0039] In summary, the first and second fixing covers, after fixing the upper ends of the outer surfaces of two adjacent corrugated pipes, adapt to corrugated pipes of different diameters by the lateral movement of the extrusion plates. The first threaded rod, after adjusting the distance between the first and second fixing covers, further adapts to the distance between the adjacent corrugated pipes. After the first and second fixing covers are used as a set to adapt to the corrugated pipes, adjacent sets of the first and second fixing covers can overlap each other through extended plates, and are fixed by a pair of connecting frames mirrored and threaded together. The fixed connecting frames pass through the mounting groove and fix the adjacent extended plates, thus fixing the adjacent sets of the first and second fixing covers. The different positions of the connecting frames within the mounting groove can further adjust the distance between the two sets of the first and second fixing covers. Furthermore, after the upper ends of the corrugated pipes are wrapped and connected, the corrugated pipes will not shake or shift during concrete pouring. The fixing device can be disassembled and reused after concrete pouring. The upper end of the corrugated pipe is fixed by the fixing device, avoiding the use of reinforcing bars at the upper end of the corrugated pipe, thus saving on the use of reinforcing bars.
