详细介绍
 水膨胀止水带采用国家标准GB18173.3-2002标准检测和生产的表如下: 项目 性能要求 PN-150 PN-220 PN-300 体积膨胀倍率(%) ≥150 ≥220 ≥300 高温流淌性(80℃×5h) 无流淌 无流淌 无流淌 低温试验(—20℃×2h) 无脆裂 无脆裂 无脆裂
The expansion of water sealing strip with the national standard GB18173.3-2002 standard testing and production are as follows: PN-220 project performance requirements PN-150 PN-300 volume expansion rate (%) = 150 = 220 = 300 (80 C high temperature flow of #215; 5H) without flowing without flowing without flowing test at low temperature (20 DEG C - #215; 2H) no no embrittlement no embrittlement embrittlement
止水带的施工与安装
Construction and installation of water stop belt
止水带是在混凝土浇注过程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,影响止水效果,具体注意事项如下:
The waterstop is in the concrete pouring process of 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 a lot of external force, so the gap will be expanded. Waterstop positioning and concrete pouring process, should pay attention to positioning method and pouring pressure, so as to avoid the water stop is punctured, influence the sealing effect, the specific considerations are as follows:
一、止水带不得长时间露天曝晒,防止雨淋,勿与污染性强的化学物质接触。
First, the waterproof belt can not be exposed for a long time in the open air, to prevent rain, do not contact with polluting chemicals.
二、在运输和施工中,防止机械、钢筋损伤止水带。
Two, in the transportation and construction, to prevent mechanical, steel damage water stop.
三、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。
Three, 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.
四、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(图),如需穿孔时,只能选在止水带的边缘安装区,不得损伤其他部位。
Method four, fixed strip: the use of additional reinforcement fixed and special fixture, fixed wire and fixed template (Figure), such as perforation, can only choose the installation area on the strip edge, not to damage other parts.
五、用户定货时应根据工程机构,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,如用户连接困难,我公司可派技术人员现场指导。
Five, the user order should be based on the engineering 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, such as site connection, can use electric heating plate vulcanization bonding or cold bonding (rubber waterstop) or welding (plastic waterstop) method, such as user connection difficulties, our company can send technical personnel on-site guidance.
