贵阳防火玻璃厂家为您介绍防火玻璃幕墙的技术要点及难点

1.GAISHU

贵阳防火玻璃厂家发现在建筑设计中,因建筑的高度、使用性能、重要性和火灾扑救难度等,把建筑分为一级、二级、三级、四级的耐火等级,建筑越高、越重要的建筑的耐火等级要求就越高,耐火等级一级为最高。不同耐火等级的建筑,其防火分区的面积也不相同。按照《建筑设计防火规范》的防火防烟等要求,在避难层、步行街、中庭等位置,必要时,必须采用防火玻璃幕墙,以防止火势的蔓延,阻止窜烟,以保证疏散及避难的安全性。

贵阳防火玻璃厂家发现防火玻璃幕墙的钢立柱应设置为垂吊受拉式,应避免采用坐立承压式,以避免在火情时受压失稳,进而导致倒塌、破坏。采用垂吊受拉式钢立柱的防火玻璃幕墙系统,钢型材一般是不需要做防火涂料处理的,但防火幕墙整体系统的耐火性能应有相关的试验报告,以试验报告的结果为准。防火玻璃幕墙耐火试验如下图所示:

复合防火玻璃是由浮法玻璃(或半钢化玻璃、钢化玻璃)和防火胶夹层组成的。火情时,因受火面玻璃遇到高温后很快就炸裂了,防火胶夹层慢慢发泡膨胀,最大可以发泡膨胀约十倍。复合防火玻璃固定在钢结构明框支承结构的槽口内,虽玻璃的防火胶夹层受热膨胀,但受火面玻璃遇到高温后很快就炸裂了,因而明框槽口内防火玻璃防火胶夹层会向已破碎的面板等没有约束的方向膨胀,虽槽口内的防火玻璃防火胶夹层在进出位方向也会有微量的膨胀,但钢结构在火情高温作用下,钢结构高温,钢结构槽口的刚度变弱,有利于适应复合防火玻璃的微膨胀需求,从而达到耐火完整性的要求。防火胶夹层发泡膨胀,吸收火焰燃烧所带来的高热量,形成不透明的防火胶板,有效起到阻隔热传导的作用。在火烧到一定时间后,防火胶受热发泡膨胀,最后脱落,进而导致下一片玻璃的破碎,下一片防火胶的受热发泡膨胀,有效阻隔热传导。

对采用单片防火玻璃或由其组成的夹胶或中空玻璃的只有耐火完整性要求的防火幕墙,其钢龙骨不应采用防火涂料。在火情时,玻璃受火面温度急剧升高,玻璃受热而热胀,玻璃向受火侧鼓起,玻璃很快形成大肚子。这时,没有防火涂料的钢型材,因受火侧的温度急剧升高,钢材在受火一侧也受热而热胀,并向受火侧鼓起,钢架也将形成大肚子,从而达到了变形的协调。
