In the embedded rubber water stop belt, which is a key for the joint and expansion joint seal of concrete internal set with product deformation in concrete, has the ability to adapt to concrete deformation with elastic rubber material and structure. This product is the use of rubber elasticity and high compression deformation, elastic deformation under various loads, so as to effectively prevent the sealing of building components Water Leakage, seepage, and play a cushioning, can ensure the service life of the building project.
Application and adaptive temperature:
Common type: +60 - 25 DEG C c;
Hardy: 40 DEG C +60
There are two methods for the joint of the embedded rubber water stop: one is to use the adhesive to carry out cold joint, and the other is to use the heat curing mould to heat the joint.
Below introduces two kinds of adhesive joint method: cold connection is the use of rubber sealing strip with special cold glue, overlapped by the waterstop joints with grinder grinding section to 5~10 cm, glue can be compacted, has high strength, fast solidification has the advantages of convenient, time-saving, can meet the general engineering quality request.
The spot heat transfer vulcanization joint is the heat vulcanization mold matched with the water stop strip and the field heat vulcanizing of the raw film. The construction is difficult, but the joint effect is ideal, which is suitable for the strict requirements of the project quality.
The structure can be divided into two types: CB type water stop belt and CP type water stop belt.
CB type water stop belt refers to the middle buried water stop with holes in it, which can be divided into two types: CB rubber water stop belt and CB plastic water stop belt. Mainly applicable to all kinds of concrete structures of expansion joints, settlement joints and seismic joints, etc., with concrete anchor tight, water seal and adapt to deformation joint expansion and deformation ability excellent.
CP type water stop belt refers to the middle hole free water stop belt, which can be divided into two types: CP rubber water stop belt and CP plastic water stop belt. The construction is mainly applicable to a variety of small deformation of concrete structures in the joints, full contraction joints and incomplete contraction joints, expansion joints, anchorage and concrete, has the characteristics of tight seal and elastic tensile deformation etc..
We design and choose the standard for this kind of rubber waterproof belt: in the process of engineering design and construction selection, the width and thickness of CB type buried rubber water stop belt should be determined according to the following conditions:
1. When the water pressure is less than 4m, the horizontal and vertical deformation amount is not more than 10mm, the width of CB type buried rubber water stop belt should not be less than 200mm, and the thickness should not be less than 5mm;
2, the water pressure is 4-8M, the horizontal and vertical deformation amount is not more than 30mm, the CB type buried rubber water stop width should not be less than 300mm, the thickness should not be less than 6mm;
3 when the water pressure is greater than 8m, the horizontal and vertical deformation exceeds 30mm, the width of CB type buried rubber water stop belt should not be less than 350mm, and the thickness should not be less than 8mm;
4, the water pressure is not greater than 8m, the horizontal deformation is not more than 20mm, when there is no vertical deformation, CB type of buried rubber water stop width should not be less than 200mm, the thickness should not be less than 5mm.
In addition, when the structural section size is greater than 500mm, the width of CB type buried rubber water stop belt should not be less than 300mm, and when the CB type water stop strip is bent, the turning radius of 300mm type waterproof rubber belt should not be less than 0. In the embedded rubber water stop belt products according to the standards of the waterstop GBl8173.2 - 2000 is the use of rubber with high elasticity and compression deformation, elastic deformation under various loads, and economical in embedded rubber water stop belt sealing to effectively prevent the fastening of building components Water Leakage, seepage, and play a buffer role, can be to ensure the service life of the building project.
