651型止水带是止水带的一种常用型号，属于中埋式止水带，中心孔两侧各有3个突起的楞，具体型式请见图，而651型橡胶止水带又是止水带产品里使用广泛的，常用的中埋式止水带还有652型、653型等。The 651 type sealing strip is a common type of sealing strip, belonging to medium buried waterstop, the center hole of each of the 3 sides of the protruding arris, the specific type is shown in Figure 651, type rubber sealing belt is widely used in sealing products, commonly used in buried waterstop and type 652, 653 type.
651型止水带安装在施工中，在混凝土浇注过程式中把橡胶止水带部分或全部浇埋在混凝土中，如果混凝土中有许多尖角的石子和锐利的钢筋头，由于橡胶的撕裂强度比拉伸强低3-5倍，因此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，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，以免被刺破，影响止水带的防水效果,具体注意事项如下: A、橡胶止水带不能长时间露天曝晒，防止雨淋，勿与污染性强的化学物质接触。The 651 type waterstop in construction, the rubber sealing strip of all or part of pouring buried in concrete in concrete pouring process, if there are many sharp stones and sharp head reinforced concrete, the tear strength of rubber and low tensile 3-5 times, so once punctured or torn, without a great force 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 was punctured, so in the waterstop positioning and concrete pouring process, should pay attention to positioning method and pouring pressure, so as not to be punctured, affecting sealing waterproof effect with the specific considerations are as follows: A, rubber sealing can not long time outdoor exposure, to prevent rain, do not contact with the chemical substances with strong.
产品应存放场所最好保持-10℃－+30℃，相对湿度在40%－80%。 B、在产品的运输和施工中，防止机械，钢筋损伤。成品存放和运输中应取直平放，勿加重压。The product should be stored to keep the best places for -10 +30 C C, relative humidity in 40%80%. B, in the transportation and construction of the products, prevent mechanical and steel damage. In the storage and transportation of the finished product, it should be put in flat, without heavy pressure.C、在施工过程中，产品安装必须固定，避免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。C, in the process of construction, the installation of the product must be fixed to avoid the displacement of concrete in the concrete and to ensure the correct position of the water stop in the concrete.D、通常我们固定止水带的方法有：利用附加钢筋固定；专用卡具固定；铅丝和模板固定等，如需穿孔时，只能选在止水带的边缘安装区，不得损伤其它部分。D, we usually fixed strip methods are: the use of additional reinforcement fixation; special fixture fixed; the wire and the fixed template, such as perforation, can only choose the installation area on the strip edge, not to damage other parts.E、用户定货时应根据工程结构，设计图纸计算好产品长度，异型结构要有图纸说明，尽量在工厂中将止水带连接成整体，如需在现场连接时，可采用电加热板硫化粘合或冷粘接(橡胶止水带)或焊接(塑料止水带)的方法，如用户连接有困难，我公司可派技术人员现场指导。 止水带分类止水带系采用弹性材料，并掺加多种辅加助剂，经混炼、硫化而制成。
E, the user order should be based on the engineering structure design drawings, calculate the length of products, have special structure drawings and specifications, try to connect into a whole band in the factory will stop, if necessary in the field of connection, can use electric heating plate vulcanization bonding or cold bonding (rubber waterstop) or welding (plastic waterstop). Methods, such as the user is connected with the difficulties, our company can send technical personnel on-site guidance. The classified water stop belt of the water stop belt is made of elastic material and mixed with a variety of auxiliary additives, and is made by mixing and vulcanization.
