core tip: steel edge waterstop is a new type of rubber waterstop, which inserts hot-dip galvanized steel strip into the middle of vulcanized rubber. It is suitable for many large-scale construction fields, especially when the water pressure is high and the structural deformation is large, Its water stop effect is more obvious. With the use of ordinary rubber Waterstops, when the structure becomes widely used in building materials, automobiles and electronic appliances, the rubber Waterstops will lengthen and become thinner with the settlement of the structure, and when it exceeds its fatigue deformation limit, it is likely to form new leakage cracks. When the steel edge rubber waterstop is used, the steel edges on both sides are strongly bonded to the surrounding concrete structure. Both the steel edge and the rubber are firmly bonded to the steel edge and the rubber. When the structure is deformed, only the rubber part is lengthened and thinned, and there will be no new leakage gap between the steel edge and concrete, or between the steel edge and rubber. Therefore, the use of steel edge rubber Waterstops is to enhance the end
today hengshuihui let Haier New materials participate in the development and design of refrigerators, air conditioners, washing machines and other household appliances. Huang Engineering Rubber Co., Ltd. focused on the installation method of steel edge rubber Waterstops and how to choose steel edge rubber Waterstops
steel edge waterstop is a new type of rubber waterstop, which inserts hot-dip galvanized steel strip into the middle of vulcanized rubber. It is suitable for many large-scale construction fields, especially when the water pressure is high and the structural deformation is large, its waterstop effect is more obvious. With the use of ordinary rubber waterstop, when the structural deformation is large, the rubber waterstop will lengthen and thin its transverse section with the settlement of the structure. When it exceeds its fatigue deformation limit, it is likely to form a new leakage gap. When the steel edge rubber waterstop is used, the steel edges on both sides are strongly bonded to the surrounding concrete structure. Both the steel edge and the rubber are firmly bonded to the steel edge and the rubber. When the structure is deformed, only the rubber part is lengthened and thinned, and there will be no new leakage gap between the steel edge and concrete, or between the steel edge and rubber. Therefore, the use of steel edged rubber Waterstops enhances the anti-seepage performance during structural deformation, and plays an important quality assurance role in the anti-seepage and water stop of the whole project
the rubber waterstop has good elasticity, wear resistance, aging resistance and tear resistance, strong adaptability to deformation, good waterproof performance, and the temperature range of use is -45 ℃ - +60 ℃ Rubber Waterstops shall not be used when the temperature exceeds 70 ℃ and the rubber Waterstops are subject to strong oxidation or erosion by organic solvents such as oil. The section of the steel edge waterstop adopts non equal thickness structure, which is divided into strength area and waterproof area, so that the stress of each part is uniform and reasonable. The long wall of the expansion hole is a plane from the perspective of adverse factors. During construction, the contact surface of the plate mold clamping is large and not easy to dislocation; An installation hole is added at the steel edge to connect with the reinforcement, which is firmly fixed and not easy to move. The good adhesion between galvanized steel edge and concrete makes the waterproof performance better
1. The structural construction joints are waterproof with steel edge embedded Waterstops, and the construction joint interface is painted with cement-based permeable crystalline waterproof paint after roughening and washing. Pay attention to the protection of rubber Waterstops during roughening
2. Installation of rubber waterstop: lap the joint of steel plate rubber putty waterstop by 100mm, press it by hand to remove the air, and bond it firmly by itself. After reinforcement and wire rolling, re stick the protective film. The steel plate putty waterstop is installed in the middle of the wall and fixed on the reinforcement with iron wire. The waterstop is slightly higher than the concrete interface
3. Precautions for rubber construction and installation: use reinforcement or formwork to position the waterstop. Generally, half of the water stop belt between construction joints is poured into the concrete first, and the other half is embedded in the concrete during the second phase construction
