Take that back stick type waterstop or external type waterstop post type rubber seal, is a kind of structures in underground concrete wall lateral deformation seam, settlement joints (upstream) a water seal structure set, has to adapt to the deformation ability of concrete telescopic elastic structure and form of the water stop.
Classification of externally bonded rubber seals
From the choice of materials, it can be divided into external rubber sealing tape, external sticking plastic water stopping belt, external sticking type water stop belt joint and embedded water expansion water stopping belt and so on. The structure can be divided into two types: EB type water stop belt and EP type water stop belt. It is worth noting that the belt is arranged in the concrete to meet the water with water type, in the construction process often requires welding sealing and waterproof board, so in this case should be s e l e c ted with the same material with waterproof board type waterstop (such as EVA EVA waterproof board post type water stop), after another post type waterstop used in Backfill Concrete Wall outside should pay attention to the protection of external plaster type waterstop.
Externally bonded rubber water stop
外贴式止水带价格外贴式止水带规格、常用规格、300×8 350×8 400×8 该止水材料具有良好的弹性，耐磨性、耐老化性和抗撕裂性能，适应变形能力强、防水性能好，温度使用范围为-45-+60。当温度超过70，以及橡胶止水带受强烈的氧化作用或受油类等有机溶剂侵蚀时，均不得使用橡胶止水带。
Post type waterstop price post type waterstop specifications, common specifications, 300×8 350×8 400×8 the sealing material with good elasticity, abrasion resistance, aging resistance and tear resistance to deformation ability, good waterproof performance, temperature range of -45 DEG -+60 deg. Rubber seals shall not be used when the temperature exceeds 70 DEG C and the rubber band is subjected to strong oxidation or is attacked by organic solvents such as oils.
Function and principle
The externally bonded rubber water stop belt is made of high elasticity of rubber and produces elastic deformation under various loads, thus achieving strong sealing, effectively preventing the leakage of building structure, seepage and shock absorption and buffering effect. In many engineering architectural design, there are certain requirements between the telescopic construction, soil structure, and there are problems such as waterproof and shockproof, so using and installing the rubber sealing strip is effective means to solve these problems. This product is mainly used in concrete cast-in-place construction joints and deformation joints, and foundation engineering, concrete structure has become one of the underground facilities, tunnel, culvert aqueduct, dam etc., to ensure the construction of service life. 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.
Technical standard for externally bonded rubber water stop
The externally bonded rubber water stop belt is produced by adopting national standard GB18173.2-2006 macromolecule waterproof material water stopping belt. Therefore according to the production of various shapes and sizes of rubber sealing requirements, need also for different parts of engineering, preparation of a cross, T-shaped, slope type and internal and external rotation type products, can be applied to any design requirements. In the product of water stop belt, direct sunlight should be avoided, and do not touch with heat source, oil and harmful solvent. The finished product should be taken straight and flat, without heavy pressure. The best places to keep -10 +30 stored C C, relative hum i dity in 40％80％. The application scope of back bonded rubber water stop: it is applied to underground structures, dams, storage tanks, swimming pools, roofing and other building materials and structures.
