Waterproof casing, flexible waterproof casing, rigid waterproof casing, 02S404 waterproof casing

Waterproof casing How to deal with the part of the flexible waterproof casing that protrudes from the wall? When pipes pass through walls and floors and metal casings (exterior walls) or plastic casings are installed, the top of the casing installed in the floor should be 3 mm higher than the decorative floor. The top of the casing installed in the bathroom and kitchen should be higher than the decorative floor. mm and the bottom of the casing should be flush with the bottom of the floor. The two ends of the casing installed in the wall should be flush with the finish. The gap between the casing and the pipe that passes through the floor should be filled with flame-retardant dense material and waterproof ointment and the end face should be filled. The gap between the smooth wall-penetrating casing and the pipe should be filled with flame-retardant dense material and the end face should be smooth. The interface of the pipe should not be located inside the casing. Finally, a rigid waterproof casing is added to the place where it passes through the floor slab. During pipeline installation, the operator has a large space utilization range and can use it freely. The operator's space for maintenance and pipe replacement after the user moves in is very limited. Pipe supports and casings can only be used to temporarily fix the pipes for corresponding operations. At the same time, the setting of the casing can also avoid damage to the interior decoration of the room when the pipe is replaced. If the casing is not provided, the wall surface will be damaged where the pipe passes through the wall when the above operation is performed. Gongyi Zhongjian Machinery Manufacturing Co., Ltd. customizes various special models of waterproof casings for customers. High-quality products with quality assurance are welcome to consult and negotiate. Waterproof casings can protect pipes from being damaged and are convenient for installing and repairing pipes. The casings in rooms with water can also prevent water from seeping into the lower floors. They can also prevent cross-contamination. So what is the point of adding waterproof casings where they penetrate the floor? Woolen cloth? After the pipe passes through the floor slab, some construction workers do not perform civil construction formwork for convenience and trouble, but simply block it and fill the hole with cement mortar. In addition, the surface of the hard polyvinyl chloride pipe is relatively smooth and the bond with the concrete is not very strong, so it is very easy to cause serious floor seepage. The phenomenon affects the normal use of residents. The correct approach is to pre-casing the pipes. After installation, formwork should be carried out in conjunction with civil engineering and fine stone concrete should be poured and compacted in two stages. After the pouring is completed, combined with the construction of the leveling layer or surface layer, a water-blocking ring with a thickness of not less than 1 mm and a width of not less than 1 mm should be built around the pipe.
