Description

TECHNICAL FIELD

[0001] The utility model relates to water stop screw especially early dismantling type three -segment type water stop screw 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 pouring thickness of concrete. The traditional water stop screw is of one -segment 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 appears in the market, which changes from one -segment structure to three -segment structure, also known as three -segment water stop screw. The three -segment 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. Like ordinary water stop screws, it is used to build concrete pouring forms 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 removed from the middle screw embedded in the wall for recycling. The recycled end screw can be reused with a new middle screw.
