背贴式橡胶止水带作用与原理背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。

　　Back stick type rubber waterstop effect and principle of back stick type rubber sealing strip is using high elastic rubber, produce elastic deformation under various loads, so as to strengthen the sealing, effectively prevent the construction of the Water Leakage, seepage and play a cushioning. 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.

　　Technical standard for back bonded rubber water stop

　　背贴式橡胶止水带在众多建筑、水利工程的得以应用,在建筑工程中或桥梁建设中由于不能连续浇注,或由于地基的变形,或由于温度的变化引起的混凝土构件热胀冷缩等原因,需留有施工缝、伸缩缝、沉降缝、变形缝,在这些缝处必须安装橡胶止水带来防止水的渗漏问题。背贴式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。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。

　　Back stick type rubber sealing strip used in many buildings, 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. 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.

　　背贴式橡胶止水带是一种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.橡胶止水带是利用橡胶的高弹性和压缩变形性的特点,背贴式橡胶止水带在各种载荷下产生弹性变形,从而起到有效紧固密封,防止建筑构造的漏水、渗水及减震缓冲作用的止水带产品。 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,影响止水效果,在施工单位进行具体注意事项如下:

　　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, in the process of water stop positioning and concrete pouring and tamping, attention should be paid to the positioning method and pouring pressure, so as to prevent the water stop being punctured and affect the sealing effect, and the specific precautions for construction units are as follows:

　　1、不得将背贴式橡胶止水带长时间露天曝晒,防止雨淋,勿与污染性强的化学物质接触。

　　1, not to back affixed rubber waterproof tape for a long time exposure to the outside, to prevent rain, do not contact with polluting chemicals.

　　2、在运输和施工中,防止机械,钢筋损伤止水带。

　　2, in the transportation and construction, to prevent mechanical, steel damage water stop.

　　3、施工过程中,止水带必须可靠固定,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。

　　3, in the construction process, the water stop belt must be reliably fixed, to avoid displacement when pouring concrete, to ensure the correct position of the water stop belt in concrete.

　　4、通常进行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。

　　4, usually fixed waterstop 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.
