止水钢板的定义:建筑物地下室水平构件和竖向构件无法一次性浇筑,一般采用在基础底板上返300mm位置留置水平施工缝,施工缝位置放置止水钢板。止水钢板一般在400mm宽,新旧混凝土内各埋置一半。
The definition of water stop steel plate: the horizontal components and vertical members of building basement can't be poured at once. Generally, it is used to return to the 300mm position on the base floor and retain the horizontal construction joints, and the construction joints are placed on the water stop steel plates. The steel plate is generally in 400mm wide and half of the new and old concrete.
止水钢板的原理为:新旧混凝土接缝位置称为施工缝,此属于防水混凝土防水的薄弱环节,增加止水钢板后,水沿着新旧混凝土接茬位置的缝隙渗透时碰见止水钢板即无法再往里渗,止水钢板起到了切断水渗透路径的作用。及时沿着止水钢板与混凝土之间的缝隙渗透,止水钢板有一定宽度,也延长了水的渗透路径,同样可以起到防水作用。
The principle of sealing steel is called the joint position of new and old concrete construction joints, the waterproof concrete belongs to the weak links, increase the sealing plate, the water along the slit Jiecha position of the new and old concrete permeability met when the sealing plate can not leaking, sealing steel plays a role to cut off the water penetration path. In time, seepage along the gap between the water stop steel plate and the concrete will have a certain width, and the permeation path of the water will also be prolonged. It can also play a waterproof role.
工作原理: 钢板止水带又叫止水钢板,是各种大型工程中常用的防水材料,材质分钢板、铜板、合金钢板等,主要用于钢筋混凝土结构、水坝及其它大型工程。 采用钢板止水带,可有效的改变水的渗透路径,延长水的渗透路线。在渗漏水可能含有腐蚀成分的施工环境中,钢板止水带能起到非常好的抗腐蚀作用。 在防护工程中,采用钢板止水带可确保工程的防护效果,对于常用于抗渗要求较高、且面积小的工程,如冶炼厂的浇铸坑、电炉基坑等也可以使用。 止水钢板常用规格为:200*2、200*3、300*2、300*3、350*2、350*3、400*4、450*4等,可 根据用 户要求订做。
Working principle: steel water stop and water stop steel plate are commonly used waterproof materials in various large projects. They are made of steel plate, copper plate and alloy steel plate, etc., which are mainly used for reinforced concrete structures, dams and other large projects. The use of steel plate can effectively change the permeation path of water and extend the permeation route of water. In the construction environment where the leakage water may contain corrosion components, the steel plate of the steel plate can play a very good corrosion resistance. In the protection engineering, the steel plate waterstop can ensure the protection effect of the project, and it can also be used for projects commonly used in high permeability and small area, such as smelting pit, electric furnace foundation pit and so on. The usual specifications of the water stop steel plate are: 200*2, 200*3, 300*2, 300*3, 350*2, 350*3, 400*4, 450*4 and so on, which can be customized according to the requirements of the user.
