TECHNICAL FIELD

[0001] The utility model relates to water stop screw especially relates to steel plastic integrated three section type water stop screw and belongs to building construction technical field. BACKGROUND

[0002] Water stop screw is usually used for the pouring of shear wall and plays the role of fixing formwork and controlling the thickness of concrete pouring. The traditional water stop screw is of one-section structure, usually a full-thread screw, with a water stop piece welded in the middle or an expansion water stop ring sleeved, to prevent water from passing through the basement wall. In order to save steel, a new type of water stop screw has appeared in the market, which changes from one-section structure to three-section structure, also known as three-section water stop screw. The three-section counter-pulling water stop screw is composed of two symmetrical end screws connected by a middle screw. The middle screw is provided with a water stop piece and two stops, which is used for building a concrete pouring form like ordinary water stop screw and does not need to change the existing construction process, and is easy to popularize and apply. After the concrete pouring is completed and the formwork is removed, the end screw can be taken off the middle screw embedded in the wall for recycling. The recycled end screw can be reused with a new middle screw.

To facilitate the rotation of the first disc 21, and to facilitate the insertion of the threaded rod 202 into the threaded hole 201 by screwing it, thereby facilitating the fixing of the fixing plate 20 and the first disc 21, the fixing mechanism 2 includes a fixing plate 20 fixedly connected to one side of the cone 11. A threaded hole 201 is provided on one side of the fixing plate 20, and the first disc 21 is rotatably connected inside the fixing plate 20. An arc-shaped groove 205 is provided on one side of the first disc 21, and a connecting plate 29 is fixedly connected to the outer circumferential surface of the first disc 21. The connecting plate 29 is internally threaded. The second disc 23 is fixedly connected to a threaded rod 202. To facilitate the fixing of the second disc 23, a bracket 22 is fixedly connected to one side of the fixing plate 20. The second disc 23 is fixedly connected to one side of the bracket 22. To facilitate the sliding of the support block 24 on the second disc 23 by rotating the first disc 21, and also to facilitate the insertion of the protrusion 28 into the positioning groove 27 to fix the connecting rod 12, a support block 24 is movably connected inside the second disc 23. A movable rod 25 is fixedly connected to one side of the support block 24. The movable rod 25 is slidably connected to the inner wall of the arc groove 205. A protrusion 28 is fixedly connected to one side of the support block 24. The connecting rod 12 is provided with a positioning groove 27 for the insertion of the protrusion 28.

[0030] In one embodiment, to improve the stability of fixing the second disc 23, three brackets 22 are provided, and one side of each bracket 22 is fixedly connected to the outer circumferential surface of the second disc 23. To improve the stability of fixing the connecting rod 12, a through groove 26 is provided on one side of the second disc 23, and a support block 24 is slidably connected to the inner sidewall of the through groove 26. There are three through grooves 26, and the three through grooves 26 are distributed at equal angles on the circumferential surface of the second disc 23. To facilitate the rotation of the connecting plate 29 by the handle 207, and to increase the friction between the palm and the handle 207, a handle 207 is fixedly connected to one side of the connecting plate 29, and a rubber block is fixedly connected to the handle 207.

[0031] In one embodiment, to facilitate the positioning of the connecting rod 12 on the second disc 23, a slot 206 is provided on one side of the second disc 23, and a plug block 17 for inserting into the slot 206 is fixedly connected to one end of the connecting rod 12; to improve the stability between the connecting rod 12 and the casting mold, a hexagonal seat 13 is fixedly fitted on the connecting rod 12, and a threaded protrusion is fixedly provided at one end of the connecting rod 12 near the hexagonal seat 13; a fixing bracket 14 is slidably connected to the connecting rod 12, and a nut 15 is threadedly connected to the connecting rod 12; to facilitate the tightening of the threaded rod 202 with a wrench, a fixing block 203 is fixedly connected to one end of the threaded rod 202, and a groove 204 is provided on one side of the fixing block 203; to improve the structural strength of the waterstop 10 and the rod body 1, equidistant reinforcing ribs 16 are fixedly connected to both sides of the waterstop 10.

[0032] In operation, the operator first inserts the insert 17 on the connecting rod 12 into the slot 206, then aligns the positioning groove 27 on the connecting rod 12 with the protrusion 28. The operator then grips the handle 207 and moves it along the threaded hole 201, simultaneously causing the first disc 21 fixed on the connecting plate 29 to rotate inside the fixed plate 20. This allows the movable rod 25 to slide along the inner wall of the arc-shaped groove 205, while simultaneously causing the support block 24 connected to the movable rod 25 to slide along the inner wall of the through groove 26. Since the second disc 23 is fixed to the fixed plate 20 by the bracket 22, the support block 24 can move towards... The connecting rod 12 slides in the direction of the slide; thereby, the protrusion 28 on the support block 24 can be inserted into the positioning groove 27. At the same time, by turning the threaded rod 202 clockwise, the threaded rod 202 is screwed into the threaded hole 201, thereby achieving the positioning and fastening of the connecting rod 12. Then, the cone 11 is screwed into the rod body 1. By placing a wooden board or other filler between the mold for casting the wall and the fixing frame 14, the nut 15 is loosened and the fixing frame 14 is pulled to adjust its position. One side of the fixing frame 14 is attached to the wooden board or other filler. Then, by tightening the nut 15, the fixing frame 14 and the mold for casting the wall are stabilized, thereby further improving the stability of the connecting rod 12.
