    Abstract: A cast-in-place coupling (6) is positioned on concrete forms (2) by detachable attachment means (7, 10). The coupling (6) may have breakaway tabs (7) or may be frictionally engaged to a fitting (10) fastened to a form (2). After concrete is poured the attachment means (7, 10) is separated from the coupling (6) with minimum effort and inconvenience. The coupling (6) itself contains an intumescent which causes the coupling (6) to convert to a firestop under file conditions.

    Abstract translation: 通过可拆卸的附接装置(7,10)将现浇联轴器(6)定位在混凝土结构(2)上。 联接器(6)可以具有分离突片(7)或者可以摩擦地接合到紧固到形式(2)的配件(10)。 在浇筑混凝土之后,以最小的努力和不便,使连接装置(7,10)与联轴器(6)分离。 联轴器(6)本身包含一个膨胀的,这使得耦合(6)在文件条件下转换成阻火器。
