The processing process of copper plate is as follows:

The first two building steel vertical bisecting base plate is fixed, the copper plate position and two building steel is in the middle, according to a horizontal building steel through the waterproof plate, and welding the water stop ring on the top of the horizontal building steel bar, the water stop ring and the copper plate in the middle welding connection, the thickness of the purple copper plate is not less than 400mm, respectively buried in the bottom plate concrete 200mm, The point pouring concrete should be higher than the bottom plate on the surface 200mm above, the thickness of stainless steel is very big 3 mm, in order to ensure that the thick steel plate has the relevant frontal bending stiffness in the construction of the project, and then the thick steel plate on both sides of the rectangular position of 50 mm pressing, about 30° edge.

When the copper plate is basically in place, the middle of the thick steel plate should avoid the vacancy as far as possible, the socket in the middle of the thick steel plate can be used for tower welding, the length of the reinforcement lap should be more than 400mm, and the welding must be welded through, the comparison of the water stop steel plate and the water stop belt, the advantage is not as good as the water stop belt, an obvious clear is rust, inconvenient post production, All try to use the water stop belt engineering construction (rubber water stop is a part of the whole process of cast-in-place concrete or all concrete pouring buried in concrete, concrete there are a lot of diagonal gravel and sharp building steel bar head because of the tear of plastic and vulcanized rubber compressive strength is 3-5 times lower than the tensile strength, rubber water stop once pierced or torn, The cracking will expand without very large external force, therefore, the precise positioning of the rubber water stop and the concrete pouring process, should pay attention to the precise positioning and pouring mode, to prevent the rubber water stop from being punctured, so in the precise positioning of the rubber water stop and the concrete pouring and the whole process, should pay attention to the precise positioning mode and pouring pressure, to prevent the rubber water stop from being punctured.
