Fireproof blocking structure between curtain wall layers and construction method
The invention discloses a curtain wall interlayer fireproof blocking structure and a construction method. The curtain wall interlayer fireproof blocking structure comprises fireproof rock wool, a cover plate, an upper supporting plate and a lower supporting plate. One side of the cover plate is bent downwards and is fixed on a reverse ridge of the main body structure through sealant, the other side of the cover plate is bent upwards and is mounted on an upper-layer transverse keel of the curtain wall through a self-tapping screw, and the middle of the cover plate is flush with the upper edge of the reverse ridge; one side of the upper supporting plate is bent downwards and installed on a boundary beam of the main body structure through fasteners, the other side of the upper supporting plate is bent upwards and fixes a backing plate of the curtain wall through sealant, and the middle of the upper supporting plate is higher than the lower edge of the reverse ridge. One side of the lower supporting plate is bent upwards and installed on the edge beam through fasteners, the other side of the lower supporting plate is bent upwards and fixes the backing plate through sealant, the middle of the lower supporting plate is lower than the lower edge of the edge beam and is supported on the lower-layer transverse keel, and an internal corner between the lower supporting plate and the bottom face of the edge beam is filled with sealant. And the fireproof rock wool is filled between the cover plate and the upper supporting plate and on the lower supporting plate. According to the invention, no influence or damage is generated on the reverse ridge, and the sealing effect is good.
本发明公开了一种幕墙层间防火封堵结构及施工方法，该结构包括防火岩棉、盖板、上托板和下托板；盖板的一边向下弯折且通过密封胶固定在主体结构的反坎上、另一边向上弯折且通过自攻螺钉安装在幕墙的上层横龙骨上、中间与反坎上边齐平；上托板的一边向下弯折且通过射钉安装在主体结构的边梁上、另一边向上弯折且通过密封胶固定幕墙的背衬板、中间高于反坎下边；下托板的一边向上弯折且通过射钉安装在边梁上、另一边向上弯折且通过密封胶固定背衬板、中间低于边梁下边且支撑在下层横龙骨上，下托板与边梁底面之间的阴角采用密封胶填充；防火岩棉填充在盖板和上托板之间以及下托板上。本发明不会对反坎产生任何影响和破坏，密封效果好。
