Description

Technical Field

[0001] The utility model relates to the technical field of water-stop screw rods, in particular to an adjustable water-stop screw rod with a stable structure. Background Art

[0002] The water stop screw is usually used for the pouring of the basement shear wall to fix the formwork. At the same time, it can stay in the wall to achieve the water stop effect. Announcement No. CN101832025B discloses a water stop screw, which includes three water stop plates with holes, a sleeve, and the three water stop plates are tightly connected to the two ends and the center end of the sleeve respectively. It also includes a sleeve with an axial small hole at one end and an axial large hole at the other end and the sleeve is connected, and a plug with an external thread at one end. Both ends of the sleeve are provided with an internal thread that matches the external thread of the plug. The thread, the large axial hole in the sleeve fits on both ends of the sleeve and the end face of the sleeve is in close contact with the waterstop. Although it can make the originally expensive disposable steel bar threaded rods be reused, the waterstop used for waterstop is directly fixed on the sleeve. Although a better waterstop effect can be achieved by setting multiple sets of waterstops, the fixed waterstop makes it difficult to adjust the position of the waterstop when the waterstop screw is used on walls of different thicknesses, making it difficult to achieve a better use effect, and improvement is needed.
