[0002] Waterstop screw is a device used in construction projects. There are one-stage and three-stage types. It is usually used for pouring basement shear walls to fix the formwork, control the thickness of concrete pouring, and stop water.

[0003] The waterstop screw is mainly composed of an intermediate screw connecting two symmetrical end screws. The intermediate screw is provided with a waterstop plate and two stops, and the end screws are provided with fastening threads and fastening nuts. After the concrete pouring is completed and the formwork is removed, the end screws can be removed from the intermediate screws buried in the wall and recycled.

DETAILED DESCRIPTION

[0032] The following will be combined with the attached examples of the present application Figures 1-6 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0033] In order to solve the problems existing in the prior art, the present embodiment provides a retractable five-section water-stop tension screw, characterized in that it includes a water-stop section;

[0034] Two telescopic sections to adjust the pulling depth according to the thickness of the side wall formwork;

[0035] Two anchor sections for fastening;

[0036] The telescopic section includes a screw sleeve 4 and a telescopic section screw 3, the telescopic section screw 3 is threadedly connected to the inner wall of the screw sleeve 4, and the screw sleeve 4 is fixed to the end of the water stop section; the anchor section is detachably installed on the side of the telescopic section screw 3 away from the screw sleeve 4.

[0037] When in use, after assembling and installing the telescopic section on the water stop section, according to the thickness of the rear inner template of the side wall, by screwing the telescopic section screw 3, adjust the extension length of the telescopic section screw 3 outside the screw sleeve 4, and then adjust the spacing between the two anchoring sections to ensure that the distance on both sides of the rubber plug 7 is equal to the wall thickness or the horizontal spacing inside the inner template, so as to be suitable for side wall templates of different thicknesses. Then, the tension screws initially formed by the water stop section and the telescopic section are installed in the template, and then the template is closed. Then, the anchoring section is installed on the telescopic section screw 3 on the outside of the template, and the anchoring section is tightened to position the template.

[0038] After pouring is completed, the anchoring section is removed and recycled from the expansion section screw 3. The recycled anchoring section can be matched with a new water-stop section and expansion section, and can be reused.

[0039] In a further embodiment of this solution, a specific structure of the water-stop section is provided: The water-stop section includes a water-stop rod 1, and a water-stop ring 2 is fixedly welded to the center of the outer wall of the water-stop rod 1 for fixing the formwork and stopping water.

[0040] In this embodiment, the screw sleeve 4 and the water-stop rod 1 are integrally formed. For example, holes are drilled at both ends of a steel column, and then the holes are tapped to obtain the integral water-stop rod 1 and screw sleeve 4.

[0041] In a further embodiment of this solution, a specific structure of the anchoring section is provided: The anchoring section includes an anchoring section screw 6, an anchoring clamp 9, an anchoring nut 8, and a rubber plug 7;

[0042] The end of the expansion section screw 3 is provided with a threaded hole 5 that cooperates with the anchoring section screw 6. The rubber plug 7 is sleeved on the anchoring section screw 6, the anchoring nut 8 is screwed and installed on the anchoring section screw 6, and the anchoring clamp 9 is embedded between the anchoring nut 8 and the rubber plug 7.

[0043] After the anchoring section screw 6 is screwed into the threaded hole 5, the connection between the anchoring section and the expansion section screw 3 can be initially realized. Continue to screw the anchoring section screw 6 until the rubber plug 7 is close to the inner side of the formwork; then screw the anchoring nut 8, and the anchoring nut 8 presses against the anchoring clamp 9, so as to tightly clamp on the outer side of the formwork and position and fix the formwork.

[0044] After pouring is completed, screwing the anchoring section screw 6 can separate the anchoring section from the expansion section, simplifying the later disassembly process of the tie rod.

[0045] In a further embodiment of this solution, the anchoring clamp 9 is in the shape of a buckled bowl. The clamping area is expanded, the bearing capacity of the lateral pressure from the formwork is improved, and the durability of the tie rod is improved.

[0046] In a further embodiment of this solution, when screwing the anchoring section screw 6 into the threaded hole 5, it is possible to drive the expansion section screw 3 to rotate, causing the expansion section screw 3 to contract or extend into the screw sleeve 4, which will affect the distance between the two anchoring sections. Therefore, in order to limit the expansion section screw 3 when screwing the anchoring section screw 6, a through hole 10 is provided at the axis of the anchoring section screw 6, a rectangular hole 12 is provided at the axis of the inner wall of the threaded hole 5, the cross section of the rectangular hole 12 is completely within the cross section of the through hole 10, and a rectangular shaft 11 is inserted into the rectangular hole 12.

[0047] When screwing the anchor section screw rod 6, insert the rectangular shaft 11 into the rectangular hole one 12 from the through hole 10. Hold the handle end of the rectangular shaft 11 and keep it stable. At this time, with the cooperation of the rectangular shaft 11 and the rectangular hole one 12, the telescopic section screw rod 3 is limited. Then, when screwing the anchor section screw rod 6 again, the influence on the telescopic section screw rod 3 will be reduced. After the assembly is completed, pull out the rectangular shaft 11.

[0048] In a further embodiment of this solution, the rectangular hole one 12 penetrates through the telescopic section screw rod 3, and the inner bottom wall of the screw sleeve 4 is provided with a rectangular hole two 13 that is exactly the same as the rectangular hole one 12.

[0049] In this embodiment, the length of the rectangular shaft 11 is greater than the sum of the lengths of the telescopic section screw rod 3 and the screw sleeve 4.

[0050] During use, after the extension length of the telescopic section screw rod 3 is adjusted, insert the rectangular shaft 11 from the through hole 10, pass through the rectangular hole one 12, and then insert it into the rectangular hole two 13. At this time, with the cooperation of the rectangular shaft 11 in the rectangular hole one 12 and the rectangular hole two 13, the telescopic section screw rod 3 and the screw sleeve 4 are relatively fixed. At this time, no longer hold the handle end of the rectangular shaft 11 with force, improving the convenience of screwing and installing the anchor section. After the assembly is completed, pull out the rectangular shaft 11.

[0051] In a further embodiment of this solution, the ports of the rectangular hole one 12 and the rectangular hole two 13 are chamfered. This improves the convenience of inserting the rectangular shaft 11.

Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and the application concept of the present application, makes equivalent replacements or changes, and should be covered within the protection scope of the present application.
