一、简介
First, brief introduction
橡胶止水带是一种常用型 号,属于中埋式止水带,中心孔两侧各有3个突起的楞,651型橡胶止水带是止水带产品里使用最广泛的止水带。主要用于在混凝土变形缝、伸缩缝等混凝土内部设置的止水带产品，具有以 橡胶材料弹性和结构形式来适应混凝土伸缩变形的能力。

Rubber water stop is a common type. It belongs to the middle buried waterstop. There are 3 protrusion lute on each side of the center hole. The 651 type rubber water stop is the most widely used waterstop belt in the water stop product. It is mainly used for sealing products in concrete, such as concrete deformation joints and expansion joints. It has the ability to adapt to the expansion and deformation of concrete in terms of rubber material elasticity and structural form.

Full use of national GB 18173.2-2014 "polymer waterproof material second parts: water stop zone" standard organization production. We can produce all kinds of products with various shapes and sizes according to user's requirements. Besides, there are cross type, T-type, slope type and inside and outside corner type rubber water stop joint products for different engineering and different parts, which can be applied to any design requirement.
三、选用标准
Three. Selection criteria
我们对于此种橡胶止水带设计及选用标准： 在工程设 计及施工选用过程中，CB型止水带的宽度及厚度应按以下条件确定:
We design and select the standard for the rubber water stop. In the process of engineering design and construction selection, the width and thickness of the CB type water stop should be determined according to the following conditions.
1、水压小于4m,水平和垂直变形量不超过10mm 时， 止水带的宽度不宜小于200mm，厚度不宜小于5mm；
1, when the water pressure is less than 4m and the horizontal and vertical deformation is not more than 10mm, the width of the water stop belt should not be less than 200mm, and the thickness should not be less than 5mm.
2、水压为4-8m，水平和垂直变形量不超过30mm时， CB型止水带的宽度不宜小于300mm，厚度不宜小于6mm；
2. When the water pressure is 4-8M and the horizontal and vertical deformation is not more than 30mm, the width of the CB type water stop belt should not be less than 300mm, and the thickness should not be less than 6mm.
3、水压大于8m,水平和垂直变形量超过30mm时，CB型 止水带的宽度不宜小于350mm ,厚度不宜小于8mm；
3, when the water pressure is more than 8m and the horizontal and vertical deformation exceeds 30mm, the width of the CB type water stop belt should not be less than 350mm, and the thickness should not be less than 8mm.
4、水压不大于8m,水平变形量不超过20mm，当无垂直 变形时，CB型止水带的宽度不宜小于200mm,厚度不宜小于5mm。
4, the water pressure is not more than 8m, and the horizontal deformation is not more than 20mm. When there is no vertical deformation, the width of the CB type water stop belt should not be less than 200mm, and the thickness should not be less than 5mm.
除此之外，当结构断面尺寸大于500mm时，CB型止水 带的宽度不宜小于300mm，当CB型止水带进行弯曲放置时，其转弯半径不得小于300mm。中埋式橡胶止水带产品标 准按止水带GBl8173.2—2000是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，从而经济型中埋式 橡胶止水带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 。本产品主要用于混凝土现浇时必须设有的永久性变形缝内，如水渠、隧道引出口、挡水坝、输水渡槽等。
Besides, when the structural section size is larger than 500mm, the width of the CB type water stop should not be less than 300mm. When the CB type water stop belt is bent, the turning radius should not be less than 300mm. In the embedded rubber water stop belt products according to the standards of the waterstop GBl8173.2 - 2000 is the use of rubber with high elasticity and compression deformation, elastic deformation under various loads, and economical in embedded rubber water stop belt sealing to effectively prevent the fastening of building components Water Leakage, seepage, and play a buffer role, can be to ensure the service life of the building project. This product is mainly used in the permanent deformation joints which must be set in the concrete casting, such as water channel, tunnel outlet, dam, water transfer aqueduct, etc.
