Now the construction engineering wall is all with concrete, the structure composition characteristic of the Build Concrete Formwork Screw Thread Water Stop Tie Rod in the building waterproof engineering, in the pouring wall or column concrete we usually use to pull the screw, can play the role of fixing the formwork and preventing the violent formwork. But because of the pull screw through the wall, the water is easy to penetrate along the screw, in the basement and the need for waterproof places put forward waterproof requirements, in order not to change the original scientific through the practice of the construction model. Water stop screw in the middle of the screw welding a square steel sheet, through the steel sheet to change the penetration path of water, so we steel sheet to water sheet, can be waterproof.
At present, a new type of water stop screw, also called three-stage water stop screw, is commonly used in construction engineering. It consists of an intermediate screw connecting two symmetrical end screws. The intermediate screw is provided with a water stop sheet and two stops, and the end screw is provided with a fastening thread and a fastening nut. The two ends of the middle screw are provided with connecting outer thread, and one end of the end screw is provided with connecting inner thread to match the connecting outer thread of the middle screw. The connection between the middle screw and the end screw is provided with a tube-shaped pad, the center part of the pad is a guard ring, and the end face of the tube-shaped pad is arranged in a circle of axial columns along the circumference, and there is a gap between each column. The end face of the pad is provided with a material saving hole. This new type of water stop bolt is connected by three screws into one, and the water stop screw is in use because it can be disassembled into three sections called the new Screw Thread Water Stop Tie Rod.
There are many construction procedures and the waterproof performance is weakened. A new type of waterproof pull screw, the two ends of the exposed screw part can be recycled, recycled, formwork can be large area one-time demoulding, efficiency increase 10~20 times, simplify the construction process, reduce construction costs, enhance the structure impermeability, effectively ensure the construction quality, progress, worthy of our further promotion and application.
New Screw Thread Water Stop Tie Rod. composition :1, the middle is waterproof to pull the inner brace, used to control the wall thickness, the wall thickness by the inner brace size consistent 2, the two ends of plastic plug for positioning reinforcement, used to locate the template 3, the two ends of the pull inner brace connected to the screw for swing screw, it can be easy to load and unload, no matter the size of the middle pull tube, swing screw can match it. The function of the water stop screw, when pouring the concrete of the basement wall or column to fix the formwork to prevent the explosion of the mold, because the rod passes through the wall, the water easily penetrates along the screw, and the water stop screw welds a square steel bar sheet in the middle of the screw called the water stop sheet, which can increase the water penetration path and play a certain role of water stop.
