橡胶止水带

　　rubber waterstop

　　橡胶止水带和止水橡皮系以天然橡胶与各种合成橡胶为主要原料，掺加各种助剂及填充料，经塑炼、混炼、压制成型，其品种规格较多，有桥型、山型、P型、U型、Z型、乙型、T型、H型、E型、Q型等。根据使用情况又可分类为埋式橡胶止水带和背贴式橡胶止水带。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。一般常在地下室外墙和后浇带施工时使用。

　　The rubber sealing strip and sealing rubber, natural rubber and various synthetic rubber as the main raw material, and the filling material mixed with various additives, through plasticizing, mixing, molding, the more varieties of different specifications, bridge, mountain type, P type, U type, Z type, T type, H type, type, E type and Q type etc.. According to the use, it can be classified as buried rubber stop belt and back sticking rubber water stop belt. The sealing material has good elasticity, abrasion resistance, aging resistance and tear resistance to deformation ability, good waterproof performance, temperature range of -45 DEG -+60 DEG. When the temperature exceeds 70 degrees Celsius, and the rubber sealing strip by strong oxidation or by oil and other organic solvent erosion, shall the use of rubber sealing strip. Generally used in the basement wall and after pouring belt construction.

　　使用方法

　　Usage method

　　橡胶止水带必需采取可靠的固定措施，绑扎钢筋和支模时。防止在浇注混凝土时发生位移，保证止水带在混凝土中的正确位置。

　　Rubber sealing tape must adopt reliable fixing measures to tie steel bar and formwork. Prevent displacement when pouring concrete, ensure the correct position of water stop belt in concrete.

　　只能在止水带的允许部位上穿孔打洞，对于固定止水带时。不得损坏止水带有效防水部位。

　　Holes can only be punched at the allowable part of the sealing strip. Do not damage the effective waterproof part of the hose.

　　常用的固定方法有:利用附加钢筋固定；专用卡具固定；用铅丝和模板固定等。不论采用何种固定方法，对于止水带的固定方法应按设计要求的施工规范进行且必需保证止水带定位准确，不损坏止水带有效防水部位，方便混凝土浇捣。

　　Fixed methods are commonly used: the use of additional reinforcement fixation; special fixture fixed with wire and fixed template. Regardless of the fixing method, fixing method for waterstop shall be according to the design requirements of the construction specifications and must ensure the waterstop positioning accuracy, does not damage the waterstop waterproof parts, convenient concrete.

　　适用范围

　　Applicable scope

　　橡胶止水带主要用于混凝土现浇时设在施工缝及变形缝内与混凝土结构成为一体的基础工程，如地下设施、隧道涵洞、输水渡槽、拦水坝、贮液构筑物等。

　　The rubber sealing belt 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..
