Water stop bolts are also split type water stop screws and waterproof screws. They are used for waterproofing and reinforcement of basement shear walls or civil defense walls, as well as for controlling formwork.
Given the drawbacks of traditional water stop screws in the past, the new three-stage water stop bolt achieves cost savings, construction convenience, and doubles the construction speed. It can also increase the speed of dismantling building formwork and achieve zero damage to the formwork.
Compared to the unified integral water stop screw, the new three-stage water stop screw is divided into three sections, with the middle part poured into the wall and the two sides can be rotated and removed for reuse to save costs.
Function: When pouring concrete for basement walls or columns, fix the formwork to prevent mold bursting. As this rod passes through the wall, water can easily penetrate along the screw, so the water stop screw welds a square steel bar in the middle of the screw called a water stop plate, which can increase the water penetration path and play a certain water stop role.
