What is a water stop bolt?

Water stop screw is also split water stop screw, waterproof screw, it is used for basement shear wall or human defense wall water stop and reinforcement as well as control the role of the template.

Compared with the traditional one whole water stop screw, the new three-section water stop screw is divided into three sections, the middle part of the casting into the wall, the two sides can be rotated to remove to do reuse and thus save costs.

Given the drawbacks of the previous traditional water-stop tensile screw, the new three-section water-stop screws to achieve cost savings, and the construction of convenient and doubled the speed of construction, but also to make the dismantling of construction templates to improve the speed of templates and do zero damage.

Expanded information:

Water-stopping screws have water-stopping pieces in the middle; when dismantling the formwork, the common wall screws are extracted as a whole and reused. When removing the mold, the ordinary through-wall screws are extracted and reused as a whole, while the water stop screws are sawed off the two ends outside the wall, and the middle section is left in the wall to ensure the impermeability of the wall.

Traditional water stop screw is a one-stage structure, usually a whole full-threaded screw with a water stop piece welded in the center or an expansion stop ring to prevent water from passing through the basement wall.

In order to save steel, there is a new type of water stop screw in the market, from a one-part structure into a three-part structure, also known as three-part tensile water stop screw.
