The advantages of the new three-stage sealing screw The new three-stage sealing screw structure is due to the superiority of the structure, in which the inner rod filaments are fine teeth and the outer rod filament teeth are t3 teeth. The outer rod and the trumpet head are welded before leaving the factory. Integrate, to reduce the use of the site process, in the process of product forging, because of its own process structure and a lot of test practice and the innovative three-stage water stop screw, in the use of the process of first connecting the outer and inner rod Up to form a one-step template construction, when the wall is molded and the mold is removed, the outer rod can be directly disassembled and used again for the next time. The outer rod can be repeatedly used for several times, so that it is also convenient for construction after the wall is formed. After the dismantling operation, the use of a new three-stage water stop screw saves money, saves time, and saves labor, greatly reducing the cost of the project.
The advantages of the old three-stage water-stop screw The three-stage water-stop screw process principle is structured in such a way that it is composed of an inner rod*1, an outer rod*2, and a joint nut*2. According to the design requirements of the structure of the thickness of the internal and external rod parts, waterproof requirements of the structure, in the middle of the rod plus welding water stop, the inner rod through the connecting part and the outer rod connection, the connection part connector nut when connecting very Big role. Three-stage sealing screw, which is widely used for reinforcement and positioning of reinforced concrete concrete wall with waterproof requirements. Through the practice of multiple underground engineering projects, the advantages of the following three stages of sealing screw are summarized as follows:
Advantages of three-stage sealing screw The three-stage sealing screw has a precise positioning of the concrete structure wall. The two sides of the template are easy to disassemble, and the assembly and disassembly are easy. The outer rod and the joint nut can be used repeatedly for circulation. The plugs at both ends are convenient. Solid, concrete structure wall appearance, cost-saving features. The three-segment type water-blocking screw has the advantages of convenient construction, convenient use of the outer rod, good waterproof effect, and obvious economic benefit compared with the conventional construction of the conventional water-stopping screw.
High speed shutter door is a rapid operating, anti-crash shutter door for indoor application . The most advantage of this door is that the opening/closing speed can reach to 0.6-1.8m/s, really fast action a lot than tranditional rollling shutter door. short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
High speed door can be easily installed, economical,quiet and efficient with electromechanical drive.
This door quickly though in/out open gate, ideal for warehouses,factories, hangars use, widths can be from 2m to 20 meters.
The material of this door are variety: PVC curtain to keep the insdie clean, heavy duty aluminum door with wind-resisitant function can wrok in heavy windy weather, and also the freezer door can be used in cold warehouse or somewhere like that.
Including models are:PVC High Speed Door, Aluminum Spiral High Speed Door, Self-Recovery repair door, Cold Storage Room Fast Door.
