bc止水带1.施工缝用橡胶止水带为橡胶止水带中的一种型号，可为分外贴式施工缝止水带和中埋式施工缝止水带，都为中间无孔型橡胶止水带，用代号表示为：CP型橡胶止水带（中埋式无孔型）和EP型橡胶止水带（外贴式无孔型）。
1. construction seam rubber sealing strip for one type of rubber sealing belt, can be particularly mounted waterstop construction joints and construction joints of buried water stop, for intermediate grooveless rubber sealing strip, with code: CP type rubber zhishuidai (embedded groovless and EP type) the rubber sealing belt (with no pass).

2.施工缝（construction joint）指的是在混凝土浇筑过程中，因设计要求或施工需要分段浇筑，而在先、后浇筑的混凝土之间所形成的接缝。 施工缝并不是一种真实存在的“缝”，它只是因后浇筑混凝土超过初凝时间，而与先浇筑的混凝土之间存在一个结合面，该结合面就称之为施工缝。因施工缝不存在真实的缝，所以在选择橡胶止水带上应选择中间无孔型橡胶止水带。
2., construction joints (construction joint) refer to the joints formed between concrete before and after pouring in the process of concrete placement, which is segmented by design requirements or construction needs. The construction joint is not a real "seam". It is simply because the post pouring concrete exceeds the initial setting time, and there is a joint between the concrete and the first poured concrete. The joint surface is called the construction joint. Because there is no real seam in the construction joint, the rubber sealing belt with no hole in the middle should be chosen in the selection of rubber water stop belt.

中埋式橡胶止水带利用橡胶的高弹性和压缩变形性，在各种荷载下产生弹性变形，从而起到紧固密封有效地防止建筑构件的漏水，渗水，并起到减震缓冲作用，可确保工程建筑物的使用寿命。
Embedded rubber water stop rubber with high elasticity and compression deformation, elastic deformation under various loads, so as to effectively prevent the sealing of building components Water Leakage, seepage, and play a cushioning, can ensure the service life of the building project.
中埋式橡胶止水带规格：
