What are the advantages of water stop screws?

1. Water stop screws can basically be divided into two categories: first-class water stop screws and third-class water stop screws.

Second, there are three types of primary water stop screws: fine-toothed primary water stop screws and medium-toothed primary water stop screws.

Then the advantages of the water stop screw can be explained from two aspects.

Compared with the traditional through-wall screw, the advantage of using the first-class water-stop screw lies in its waterproofness. Due to the rise of large-scale projects such as underground engineering and underground pipe gallery in underground garage, the traditional through-wall screw can no longer adapt to the changes of the times. Among them, the sales volume of threaded water stop screws is the largest, because it is easy to use and control.

The second explanation is the comparison between the three-stage water stop screw and the first-stage water stop screw. After using the first-class water stop screw, the exposed screw after formwork removal needs to be cut to produce waste, and the flatness of the external wall is not enough. Three-stage water stop screw came into being: one inner rod, two outer rods and two cone joints. The biggest advantage of this design is that the two external rods and the two conical joints can be reused, which greatly saves the cost, and at the same time, it is easy to form a clear wall, easy to demould and improve the utilization rate of the template. The appearance is better, which makes this three-stage water stop screw deeply loved by the majority of construction companies and sold well all over the country.
