地铁专项使用钢边止水带价格

一、止水带的作用及使用范围
First, the function and scope of use of water stop belt
止水带是利用橡胶的高弹性和压缩变形性的特点，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。
Water stop belt is a kind of rubber with high elasticity and compression deformation characteristics, under various loads to produce elastic deformation, so as to effectively tighten the seal, to prevent the construction of the water leakage, seepage and shock absorption buffer effect.
在一般较大工程的建筑设计中，由于不能连续浇注，或由于地基的变形，或由于温度变化引起的混凝土构件热胀冷缩等原因，需留有施工缝、沉降缝、变形缝，在这些缝处必须安装止水带来防止水的渗漏问题。
In the architectural design of general larger projects, due to the continuous casting, or as a result of the ground deformation, or concrete caused by thermal expansion due to temperature change and contraction, to save construction joints and settlement joints, deformation joints, these joints must be installed in the water brought to prevent water leakage problems.
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 waterstop 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..
二、技术标准
Two. Technical standards
止水带的尺寸公差、技术要求、实验方法、检验规则符合中华人民共和国国家标准GB18173.2-2000≤橡胶止水带≥全部要求。
Waterstop tolerances, technical requirements, test method, inspection rules in accordance with the national standard of Peoples Republic of China GB18173.2-2000 rubber waterstop is greater than or equal to all the requirements.
注：１、橡胶与金属粘合项仅适用于具有钢边的止水带。
Note: 1. The rubber and metal bonding items are only applicable to the water stop with steel edges.
??２、若有其他特殊需要时，可由供需双方协议适当增加检验项目，如根据用户需求酌情考核霉菌试验，但其防霉性能应等于或高于2级
2. If there are other special needs, the inspection items can be appropriately increased by the agreement between the supplier and the buyer, such as testing the mold test according to the users needs, but the mold resistance should be equal to or higher than the 2 grade
