Classification of external rubber sealing tape
从材料选择来区分可分为外贴式橡胶止水带、外贴式塑料止水带、外贴式止水带接头和中埋式遇水膨胀止水带等。从结构形式上可分为EB型止水带和EP型止水带两种。值得注意的是由于外贴式止水带设置在混凝土的迎水面，在施工过程中往往要求与防水板进行焊接密封，所以在这种情况下应选择与防水板材质相同的外贴式止水带（如EVA防水板选择EVA外贴式止水带），另外外贴式止水带使用之后，在混凝土壁板外侧进行回填时应注意对外贴式止水带的保护。
The material can be divided into external rubber sealing tape, external sticking plastic water stop belt, external sticking type water stop joint and intermediate water expansion water stop belt. 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 selected 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.

作用与原理
Function and principle
外贴式橡胶止水带是利用橡胶的高弹性，在各种荷载下产生弹性变形，从而起到坚固密封，有效地防止建筑构造的漏水，渗水并起到减震缓冲作用。在许多工程建筑设计中，土建、水土结构之间都有一定的伸缩要求，并存在防水防震等问题，因此采用和安装橡胶止水带是有效地解决以上种种问题的手段。本产品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、地下设施、隧道涵洞、输水渡槽、挡水坝等，确保工程建设的使用寿命。在橡胶止水带安装时，如果发现混凝土浇注过程式中部分或全部浇埋在混凝土中，混凝土中有许多尖角的石子和锐利的钢筋头，由于塑料和橡胶的撕裂强度比拉伸强低3-5倍，止水带一旦被刺破或撕裂时，不需很大外外力裂口就会扩大，所以在止水带定位和混凝土浇捣过程中，应注意定位方法和浇捣压力，以免止水带被刺破。
Externally bonded rubber water stop is a kind of high elasticity made of rubber, which produces elastic deformation under various loads, so as to form a strong seal, effectively prevent the leakage of the building structure, seep water and play the role of shock absorption and buffering. 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.
外贴式橡胶止水带技术标准
Technical standard for external rubber sealing tape
外贴式橡胶止水带是采用国家标准GB18173.2-2006《高分子防水材料止水带》组织生产的。因此可以按用户要求生产各种形状、尺寸的橡胶止水带，另外还为不同工程、不同部位的需要备有十字型，丁字型、斜度型和内外转角型产品，可适用于任何设计要求。在止水带产品在运输时，应避免阳光直射，勿与热源、油类及有害溶剂接触。成品应取直平放，勿加重压。存放场所最好保持-10℃－+30℃，相对湿度在40%－80%。背贴式橡胶止水带适用范围：应用于地下构筑物、水坝、贮水池、游泳池、屋面以及其他建筑物质和构筑物的变形缝防水。

The external rubber sealing tape is produced by the national standard GB18173.2-2006 "polymer waterproof material water stop 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. When the water stop belt is in transportation, it should avoid direct sunlight, and do not contact with heat source, oil and harmful solvents. The finished product should be straight and flat, without heavy pressure. The best places to keep -10 +30 stored C C, relative humidity in 40%80%. The application scope of back bonded rubber water stop is applied to the deformation joint waterproof of underground structures, dams, storage tanks, swimming pools, roofs and other building materials and structures.
