Description

木质防火门用门扇
技术领域
本实用新型涉及木质防火门设备,尤其是指用于木质防火门的门扇。
技术背景
市场上常见的木质防火门用门扇通常是木骨架中间填充岩棉或硅酸铝纤维制成成品,在实际使用过程中由于门扇的频繁开启,象岩棉、硅酸铝制品没有结构强度,在一定时间后必然会下沉,当遭遇火警时门扇顶部极易穿火,就起不到防火作用。
发明内容
本实用新型正是为了克服上述不足,提供一种结构强度高、防火作用好的木质防火门用门扇,改进之处在于抛弃填充形式,门扇改由几层板材复合构成,作为门芯的是高强度珍珠岩板,其由木质骨架固定,然后在珍珠岩板的外侧复合防火板,具体是这样来实施的:木质防火门用门扇,包括骨架、防火板,其特征在于作为门芯的珍珠岩板由木质骨架固定,珍珠岩板与木质骨架两面均复合有防火板。由于用珍珠岩板作为门芯,其强度高,门扇长时、频繁开启,不会有填充料的下沉现象发生,确保其良好的防火性能。
本实用新型防火板外面可另复合一装饰板,满足市场的审美要求。
本实用新型门扇的侧面镶嵌有防烟条,保证整个产品的防火性能。
本实用新型通过改变门扇的门芯结构,运用结构强度高的珍珠岩板结合木质骨架制成,使用中不会沉陷,防火效果好。
附图说明
附图为本实用新型的结构示意图。
具体实施方式
木质防火门用门扇,包括骨架1、防火板2,作为门芯的珍珠岩板3由木质骨架1固定,珍珠岩板3与木质骨架1的两面均复合有防火板2,在两防火板的外面还复合有装饰板4,门扇侧面镶嵌有防烟条5。
