钢板止水带又称为止水钢板。而就在箱型基础或地下室，底板和外墙板的混凝土是分开浇捣的，下次再浇捣墙板混凝土时，就有一条施工缝，当这条缝的位置在地下水位线以下时，就容易产生渗水。这样就需要对这条缝进行技术处理，处理的方法很多，其中比较通行的方法是设置止水钢板。即在浇筑下层混凝土时，预埋300*3的钢板，其中有10-15cm的上部露在外面，在下次再浇筑混凝土时把这部分的钢板一起浇筑进去，起到阻止外面的压力水渗入的作用。一般钢板止水带是采用冷轧板作为母材,因为冷板厚度能够均匀，热板一般厚度达不到均匀的程度，厚度一般为2毫米或者3毫米，长度一般加工成3米长或者6米长，一般为三米好运输。止水钢板对焊接节点要求较高，不能出现漏点，影响防水性能。
The steel plate of the steel plate is also called the water stop steel plate. In the box foundation or basement, the concrete of the floor and the external wall is separately poured and tamping. There is a construction joint when the concrete is poured again and again. When the position of the seam is below the groundwater level, it is easy to produce seepage. In this way, there are a lot of methods to deal with the seam, and the more popular method is to set up the steel plate. That is to say, when pouring the lower concrete, the 300*3 steel plate is embedded, and the upper part of 10-15cm is exposed outside. When the next concrete is poured, the steel plate will be poured together to prevent the external pressure water from penetrating. The general steel plate waterstop is made of cold rolled sheet as the base material, because the thickness of the cold plate can be even, the thickness of the hot plate is not up to the even degree, the thickness is generally 2 millimeters or 3 millimeters, the length is generally processed into 3 meters long or 6 meters long, generally three meters, good transportation. The steel plate has a high requirement for the welding node, and the leakage point can not be found, which affects the waterproof performance.
施工要点
Key points of construction
1、应尽力保证止水钢板在墙体中线上；
1, we should try to ensure the steel plate in the wall of the wall.
2、两块钢板之间的焊接要饱满且为双面焊，钢板搭接不小于20mm；
The welding between 2 and two plates is full and double-sided, and the steel plate is not less than 20mm.
3、墙体转角处的处理，一、整块钢板弯折；二、丁字型焊接；三、7字型焊接。
3, the wall corner of the treatment, one, the whole plate bending; two, T-type welding; three, 7 type welding.
4、止水钢板的支撑焊接，可以用小钢筋电焊在主筋上；
4, the support welding of water stop steel plate can be welded on the main bar with small steel bar.
5、止水钢板穿过柱箍筋时，可以将所穿过的箍筋断开，制作成开口箍，电焊在钢板上。
5. When the steel plate is passed through the column stirrup, the stirrup that is passed can be broken and made into the opening hoop, and the electric welding is on the steel plate.
6、止水钢板的“开口”朝迎水面。
6, the "opening" of the steel plate is facing the surface of the water.
