Bidirectional fireproof and smoke-proof door
The invention provides a bidirectional fireproof and smoke-proof door which comprises door leaves and a door frame. The upper end and the lower end of one side of each door leaf are connected with hydraulic door closers to achieve bidirectional opening, the side is used as a pivot joint side of each door leaf, and the other side is used as a moving side. An arc groove or arc grooves are arranged on one side or the two sides of the door frame. The pivot joint sides of the door leaves are provided with chamfered corner angles or arc faces matched with the arc grooves, and fireproof expansion sealing strips are arranged on the top sides and the pivot joint sides of the door leaves. Fireproof expansion sealing strips and/or smoke-proof and fireproof expansion sealing strips are arranged on themoving sizes of the door leaves. Smoke-proof and fireproof expansion sealing strips are arranged on the two sides and the top side of the door frame. Elastic edges extending outwards are arranged onthe edges of the smoke-proof and fireproof expansion sealing strips and are in elastic contact with the door leaves. According to the bidirectional fireproof and smoke-proof door, bidirectional opening and double-face fireproof and smoke-proof operation can be achieved.
本发明提出一种双向防火防烟门，包括门扇和门框，所述门扇的一侧的上下两端与液压式闭门器连接以进行双向开启，以该侧为门扇的枢接侧，另一侧为活动侧；所述门框的一侧或两侧设有弧面槽，门扇的枢接侧具有与所述弧面槽相契合的倒圆角边或弧面；所述门扇的顶侧和枢接侧设有防火膨胀密封条；门扇的活动侧设有防火膨胀密封条和/或防烟防火膨胀密封条；所述门框的两侧和顶侧设有防烟防火膨胀密封条；所述防烟防火膨胀密封条的边缘设有向外延伸的弹性边，所述弹性边与门扇弹性接触。本发明的双向防火防烟门，可双向开启且双面防火防烟。
