鋼板止水帶又稱為止水鋼板。而就在箱型基礎(chǔ)或地下室，底板和外墻板的混凝土是分開澆搗的，下次再澆搗墻板混凝土?xí)r，就有一條施工縫，當(dāng)這條縫的位置在地下水位線以下時，就容易產(chǎn)生滲水。這樣就需要對這條縫進(jìn)行技術(shù)處理，處理的方法很多，其中比較通行的方法是設(shè)置止水鋼板。即在澆筑下層混凝土?xí)r，預(yù)埋300*3的鋼板，其中有10-15cm的上部露在外面，在下次再澆筑混凝土?xí)r把這部分的鋼板一起澆筑進(jìn)去，起到阻止外面的壓力水滲入的作用。一般鋼板止水帶是采用冷軋板作為母材,因為冷板厚度能夠均勻，熱板一般厚度達(dá)不到均勻的程度，厚度一般為2毫米或者3毫米，長度一般加工成3米長或者6米長，一般為三米好運輸。止水鋼板對焊接節(jié)點要求較高，不能出現(xiàn)漏點，影響防水性能。
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.
施工要點
Key points of construction
1、應(yīng)盡力保證止水鋼板在墻體中線上；
1, we should try to ensure the steel plate in the wall of the wall.
2、兩塊鋼板之間的焊接要飽滿且為雙面焊，鋼板搭接不小于20mm；
The welding between 2 and two plates is full and double-sided, and the steel plate is not less than 20mm.
3、墻體轉(zhuǎn)角處的處理，一、整塊鋼板彎折；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、止水鋼板的支撐焊接，可以用小鋼筋電焊在主筋上；
4, the support welding of water stop steel plate can be welded on the main bar with small steel bar.
5、止水鋼板穿過柱箍筋時，可以將所穿過的箍筋斷開，制作成開口箍，電焊在鋼板上。
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、止水鋼板的“開口”朝迎水面。
6, the "opening" of the steel plate is facing the surface of the water.
