Construction and installation steps of steel edge rubber water stop belt
1. First, the steel edge rubber water stop belt is placed in the specified position according to the design requirements.
2. Using the installation holes of the two sides of the steel edge rubber sealing belt, the steel edge rubber waterproof belt and the steel net are tied and positioned by the iron wire. When the steel edge rubber water stop belt is positioned, the outer side of the two side steel strip is higher than the middle rubber water stop belt, and the U type installation is formed.
3, the template should be strictly according to the operation rules for construction requirements for construction and installation in steel edged waterstop intermediate rubber ring type 0 two surface plane template to the firm, beware of concrete template displacement vibration.
4, install the steel edged rubber water stop in construction must be good protection and support without pouring concrete part of the rubber sealing belt, in pouring concrete to strip near the slight vibration, especially in the lower edge of the horizontal part, sealing concrete to make concrete more subtle, the bubbles in the run out of the rubber watertight strip under the wing, when the concrete surface exceeds the waterstop plane, can cut the wire, making the waterstop is level.
5, the steel edged rubber water stop strip two side when installing the rubber watertight strip according to R requirements should turn radius in the corner, and keep the steel flat, make steel and concrete effective combination, to play a good sealing effect.
6, waterproof Belt should be properly protected during transportation, storage should be ventilated, avoid oil pollution and direct sunlight.
Note: the horizontal section of the waterstop positioning wings can also use the 6mm short bar and the mounting hole on tie construction using artificial water to remove the bubble to flank up.

钢边橡胶止水带的施工安装步骤
1、先将钢边橡胶止水带按设计要求,放在规定的部位。
2、利用钢边橡胶止水带二边的安装孔,用铁丝将钢边橡胶止水带与钢筋网捆扎定位。钢边橡胶止水带定位时应二边钢带外侧高于中间橡胶止水带形成U字型安装。
3、模板应严格按施工操作规程要求进行施工,安装在钢边止水带的中间橡胶0型环上下二面间的平面上,模板要牢固,谨防混凝土浇灌振捣时模板移位。
4、安装好的钢边橡胶止水带在施工时一定要保护和支撑好未浇捣混凝土部分的橡胶止水带,在浇捣止水带附近混凝土时要细微振捣,尤其在水平部分,止水带下缘的混凝土更要细微,使混凝土中的气泡从钢边橡胶止水带翼下跑出来,当混凝土捣面超过止水带平面后,可以剪断铁丝,使止水带呈水平状态。
5、钢边橡胶止水带二侧的钢带安装时,钢边橡胶止水带在转角处应按R的半径要求转弯,并保持钢带平整,使钢带与混凝土***结合,起到良好的止水效果。
6、止水带在运输时要妥善保护好,贮藏时应通风,避免油污和阳光直射。
注:定位水平段止水带两翼也可以用ф6mm短钢筋与安装孔绑牢,施工时用人工将止水带侧翼上翘达到排除汽泡目的。
