Water stop joints are mainly used in bathrooms, kitchens, balconies, terraces and other places where pipes pass through the floor, and are mainly used in drainage pipes.
Adopting the new technology of pre-embedded casing for water-stop joints, it mainly consists of the main body of the pipe fitting, the water-stop wing ring, the double-layer inserted socket at the bottom, the fixed support and the pipe cap.
The multi-layer grooved water-stop wing ring can greatly increase the contact length and contact surface between the drainage embedded parts and the concrete. The rougher surface makes them more closely integrated and completely eliminates water leakage. ; The double-layer inserted socket at the bottom is used to connect the lower drainage pipe to form a drainage system; the fixed support has holes for fixing the embedded parts on the large formwork; the pipe cap can protect the embedded parts Dirt and construction debris will not be spread to prevent pipe blockage and pollution.
Extended information:
1. Operation points
1. Use a glass piece (engraved with cross lines) as the base, and place it on the bottom layer according to the original setting point. Use a level ruler to level it, and then use a point measuring instrument to align the center point on the glass piece upward to measure the leading point.
2. Use iron nails to drive through the template from the bottom to mark the point.
3. Fix the embedded floor water stop casing with the marked point as the center.
2. Precautions
The installation worker should carefully check the point location. After the civil construction formwork is supported and the bottom bars are tied, the installation worker will then position the site and use appropriate round nails to penetrate it. Fix the embedded parts on the bottom formwork through the fixed holes on the connecting supports, and then cover the upper opening with a pipe cap to prevent concrete mortar and debris from falling into it.
When pouring concrete, the installation workers must guard the site, and the civil construction workers must also cooperate closely. If the embedded parts are displaced or tilted, they must be dealt with promptly; after the civil construction formwork is removed, the fixed parts must be fixed before the next process of construction. Cut off the protruding part of the round nail of the embedded part, and apply anti-rust paint on the cut area; clean the dirt inside the socket of the embedded part and apply glue, apply glue to the end face of the pipe and insert it into the double-layer inserted socket at the lower end; install the pipe The bracket fixes the pipe so that it is tightly connected to the embedded parts.
