Construction Material Sealing Screw

The water stop screw is usually used in the wall of the board that needs to stop the water, to fix the template, and at the same time it can prevent the wall from seepage. For example: basement shear wall, underground garage, pool, etc.
The water stop screw is divided into the old water stop screw and the three stop water stop screw. Now let's talk about the use of the three-stage water stop screw.
The three-stage water-stopping screw consists of an inner rod connected to two symmetrical outer rods through two joints and a stop plate in the middle of the inner rod, and a stop plate in the joint mother. In the process of pouring the wall with water stoppage, the three-stage water stop screw passes through the wall and is poured in the wall to fix the template and prevent the wall from seepage.
The water stop screw is from the inside out, followed by the wall, formwork, wood, steel pipe, mountain type cards and nuts. From the middle to the side of the screw, the water piece, the joint mother, and the nut are in turn. The water stop screw penetrates the wall of the panel, the formwork, the square, the steel pipe and the mountain type card, and is then fastened with a nut. After the concrete is poured and the template is removed, the end screw can be removed from the joint body embedded in the wall body, and the recycled outer rod and the new inner rod can be reused together.
The lengths of the inner and outer rods of the three-stage sealing screw are different, but of course the price is different. Here we must pay particular attention to the length of the middle section (inner rod), which must be accurate, and how many walls use the water stop screw of the inner rod. This is a good match. If you do something wrong, there is no way to use it. The three-stage water-stopping screw is very convenient to use, and the mold removal is simple, and the outer rod can also be recycled and reused to a certain extent to play a saving role.
