The function and principle of the back type rubber water stop belt is a back attached rubber water stop. It uses rubber&＃39;s high elasticity and produces elastic deformation under various loads, so as to play a solid seal. It can effectively prevent the leakage of building structure, water seepage and play the role of shock absorption and buffering. In many engineering building designs, there are certain requirements for expansion and contraction between civil structures and water and soil structures, and there are problems such as water and shock proof. Therefore, the installation and installation of rubber water stop is an effective way to solve these problems. This product is mainly used for concrete cast-in-place engineering, underground facilities, tunnel culverts, water conveyance aqueducts and water retaining dams, which are built in the construction joints and deformation joints, and ensure the engineering construction life.
Technical standard for backstick rubber sealing belt
Back stick type rubber sealing strip used in many domestic construction, water conservancy project, in construction engineering or bridge construction due to continuous casting, or as a result of the ground deformation, or concrete expansion caused by the variation of temperature and cold, need to have construction joints, expansion joints and settlement joints, deformation joint and in these joints must be installed to prevent the rubber sealing bring water leakage problems. Back stick type rubber strip is mainly used for cast-in-place concrete when in construction joints and deformation joints and concrete structure has become one of the basic engineering facilities, such as underground tunnels, culverts, dams, aqueducts, liquid storage structures etc.. In the rubber waterstop, if it is found that the concrete pouring process in all or part of pouring buried in concrete, there are many sharp stones and sharp head reinforced concrete, the tear strength of rubber and plastic tensile and low 3-5 times, once the waterstop punctured or torn, without external force cracks will expand, so the waterstop positioning and concrete pouring process, should pay attention to positioning method and pouring pressure, so as to avoid the water stop punctured.
Back stick type rubber strip is a kind of natural rubber and synthetic rubber as the main raw material, and the filling material mixed with various additives, through plasticizing, mixing, pressing and molding. The rubber sealing strip is the rubber high elasticity and compression deformation characteristics of back stick type rubber sealing strip to generate elastic deformation in under various loads, so as to effectively prevent water sealing cushion construction Water Leakage, seepage and damping belt products. Therefore, during the process of positioning and concrete tamping, attention should be paid to the location method and the pressure of pouring and tamping, so as to prevent the water stop from being punctured and affect the sealing effect.
1, the back affixed rubber belt must not be exposed to the open air for a long time to prevent the rain, and do not contact the chemicals with strong pollution. 2, in transport and construction, prevent machinery, steel damage stop water zone.
