What is the standard water stop screw?

1. The traditional water stop screw consists of three parts: the screw, the positioning part for controlling the wall thickness and the water stop part.

Secondary and tertiary water stop screws:

1, with waterproof internal support in the middle, which is used to control the wall thickness, and the wall thickness is consistent with the size of the internal support.

2. The plastic plugs at both ends are positioning ribs, which are used to position the template.

3. The screws connected to the two ends of the inner brace are rotating screws, which can be easily installed and disassembled. When used repeatedly, the rotating screw can match the middle inner support regardless of its size.

Function:

When pouring basement wall or column concrete, the formwork shall be fixed to prevent the formwork from exploding. Because this kind of pole passes through the wall, water can easily penetrate along the screw, so the water stop screw is welded with a square steel sheet called a water stop piece in the middle of the screw, which can increase the penetration path of water and play a certain role in stopping water.
