With the wide application of the water stop screw, there are more and more advanced three-stage water stop screw and new three-stage water stop screw, which are widely used to play a waterproof role on the wall and dam, then, what is the application principle of the water stop screw? I think many buyers are not very clear, knowledge to buy, but do not know the principle is actually a very tangled problem, feeling like a layman, so we must understand why the water screw is waterproof when purchasing the water screw, that part needs to be waterproof, what is the principle of waterproof, as long as we understand the principle inside we can know When purchasing water stop screw, we can prevent suppliers from counterfeiting in it, and the production process of water stop screw plays a great role here.
The production process of the water stop screw is actually divided into three stages, we can call it a three-stage water stop screw, and the three-stage pull water stop screw is composed of a middle screw connected to two symmetrical end screws, the middle screw is provided with a water stop sheet and two stops, and the end screw is provided with fastening threads and configured with fastening nuts. The two ends of the middle screw are provided with a connecting external thread, and the end screw is provided with a connecting internal thread and the connecting external thread of the middle screw. The joint of the middle screw and the end screw is covered with a tube-shaped pad, and the part of the pad is a retainer. One end face of the tube-shaped pad is arranged along the circumference of a circle of axial columns, and there is a gap between the columns. The end face of the pad is provided with a economizing hole. The water stop screw composed of the middle screw and the end screw is used to set up the concrete pouring mold like the ordinary water stop screw. It does not need to change the existing construction process, and it is easy to popularize and apply. After the concrete is poured and the template is removed, the end screw can be removed from the middle screw buried in the wall and recycled, and the recovered end screw and the new middle screw can be reused. And like the previous water stop screw installation when the artificial cutting is a particularly troublesome thing, and with the more and more widespread use of water stop screw, three-stage water stop screw is also used and born, three-stage water stop screw in the disassembly is also a particularly simple and labor-saving thing.
1, the traditional screw first disassemble the template, due to the resistance of the screw outside the wall, the disassembly is difficult, time-consuming and laborious, and the template consumes a lot of money. 2, the new screw in the disassembly process first disassemble the wall outside the screw (the wall inside and outside the screw is connected by the screw, easily disassembled with the wrench), at this time the template has no resistance, so it can be easily disassembled, because the operation is simple and saves time and effort, and the template is zero loss. Since the three-stage water stop screw is so good when it is used, what is the specific effect? 1, the traditional screw in the removal of the template, through the gas cutting to cut off the screw, the process of complex construction is slow, the wall partial due to high temperature cement cracking phenomenon. 2, the new screw does not need gas cutting, no emission and no pollution, the wall is smooth, the disassembly process is not damaged, which is conducive to the later construction.
This is the difference between the three-stage water stop screw and the water stop screw, so that we save time and effort during construction, and will not damage the wall, so that we feel that although the previous water stop screw is cheap on the fake, it will cause the wall to loosen without awareness of the entire wall, and even the waterproof effect will become worse and worse over time. Therefore, when we choose the water stop screw, we should choose the new three-stage water stop screw.
