Abstract

一种用于闭合墙或类似开口的门扇,它主要是由 三层桐木拼板构成,其外层两块拼板按竖纹设置,内 层拼板按横纹设置,由于改变了传统技术门扇的结构 及用料,选用材质较轻的桐木为主要原材料,所以使 得门扇具有重量轻,不易倾斜变形的优点,又由于门 扇侧壁上镶有保护条及门扇外层喷涂有防火涂料,所 以不仅起到硬化表层及保护作用,使得该门扇更加坚 固,而且还可达到防腐、防火、豪华美观的效果。

Description

本实用新型涉及一种用于闭合墙或类似开口的门扇。
通常建筑物上所使用的木质门扇可分为两种:一种是以红、白松为材料制做的五冠门,该门扇是由框架以及框架内镶嵌的木质装板构成;另一种为空腹门扇,该门扇是由框架以及框架上胶钉的胶合板构成,由于这两种门扇框架选用材质较重的红、白松为原材料以及框架式结构开榫较多,所以长期使用容易脱榫,门扇易倾斜变形,五冠式门扇装板易裂缝,空腹式门扇使用胶合板也较为单薄,坚固性较差。
本实用新型的目的在于提供一种建筑物上使用的门扇,它不仅重量较轻,不易变形,而且还具有防火功能。
本实用新型是这样实现的:选用材质较轻的桐木为原材料,门扇主要由三层拼板构成,其外层两块桐木拼板按竖纹设置,内层拼板按横纹设置,外层两块拼板厚度均为10-13mm,最佳厚度为12mm,内层拼板的厚度为14-20mm,最佳厚度为16mm,三层拼板可经热压或冷压粘合一次成型,所选用拼板为经浸泡和烘干后的桐木板,其最佳方案可选用经浸泡和烘干后的立纹桐木板,位于安装锁及合页位置处镶嵌有松木板块,以使该处更加坚固,外层板面上喷涂有防火涂料,以达到硬化表层,防腐、防火、豪华美观的目的,门扇的外侧面镶有保护条,不仅起到保护作用,而且还具有一定装饰效果。
下面通过实施例结合附图对本实用新型进行详细描述:
图1为本实用新型结构主视图。
图2为本实用新型A-A剖面图。
该轻质防火门扇主要由两外层拼板(5)和(7)及内层拼板(6)三层拼板构成,其内外层拼板均是选用经浸泡和烘干后的立纹桐木板,两外层拼板(5)、(7)的厚度为12mm。内层拼板(6)的厚度为16mm,外层拼板(5)、(7)按竖纹设置。内层拼板(6)按横纹设置,并可一次热压粘合成型,该门扇安装锁及合页处分别镶嵌有松木板块(1)、板块(2)及板块(3),门扇侧壁上镶有保护条(4),保护条(4)可选用木质、塑料或金属材料,门扇的外层喷涂有防火涂料(8)。
本实用新型由于改变了传统技术门扇的结构及用料,选用材质较轻的桐木为主要原材料,所以使得门扇具有重量轻,不易倾斜变形的优点,又由于门扇侧壁上镶有保护条及门扇外层喷涂有防火材料,所以不仅起到硬化表层及保护作用,使得该门扇更加坚固,而且还可达到防腐、防火、豪华美观的效果。
