玻璃幕墙防火分区注意要点

发布时间:2018-12-30 15:09:04浏览次数:10552文章出处:河北幕墙设计公司

  玻璃幕墙是由金属构件和玻璃板组成的建筑外墙面围护结构,分明框、半明框和隐框玻璃幕墙三种。构成玻璃幕墙开心棋牌的材料主要有:钢、铝合金、玻璃、不锈钢和粘接密封剂。在实际的幕墙设计中,应注意防火分区的设计。防火分区是指在设计中将建筑物的平面和空间以防火墙、防火门窗、防火卷帘及一定耐火极限的楼板等分成若干区。

  幕墙设计人员应正确理解防火分区概念,楼面梁及实体窗槛墙是属于上下防火分区的隔断,因此对有窗槛墙的防火分区以楼面水平线划分并不合理,而宜以楼面、楼面梁及实体窗槛墙的外沿线进行划分确定。玻璃板块并未穿越两个防火分区玻璃幕墙施工开心棋牌,与规范中的有关要求也并不矛盾,即使火灾中楼面玻璃板块破坏,由于上道防火封堵并未受到破坏,防火封堵仍可以起到有效的阻隔作用。

  建议不宜采用板块划分模式。若由于建筑原因必须采用这种划分模式时,建议楼面处的玻璃采用防火玻璃,并且立柱的伸缩缝宜稍向下设置,以错开横梁的角码位置。或者在楼面上的第一根横梁上方加做一道防火封堵,以保证即使楼面处的板块破坏但由于上道防火封堵未受破坏辽宁安利达幕墙装饰公司开心棋牌,仍可有效起到防火保护作用。但这种结构从室内看由于窗台高度过高明显影响视觉效果。
