本文首先阐明,关于具有中庭的建筑物的设计,应适当考虑中庭的排烟系统和中庭围墙及开口的性能和规格。这主要是由于中庭空间和相邻空间在大小、用途、人数及其活动方面各不相同;其次举例介绍中庭火灾性状预测方法。在这个例子中,对高80m占地面积310m2的中庭的火灾性状进行预测。在这种情况下曾证明,如果遇到下列条件,中庭会是安全的:火灾时,把中庭内部条件视为外部条件,采用中庭顶部自动排烟,同时采用底部送风口(35m2)供气。并且建筑物具有耐火1小时的铝制中庭周围幕墙、开口为固定窗,每层装有最高为1.23m的夹丝玻璃。
This article first states that with respect to the design of buildings with atriums, due consideration should be given to the performance and specifications of the smoke exhaust system and atrium walls and openings in the atrium. This is mainly due to differences in sizes, uses, numbers, and activities of the atrium space and adjacent space; In this example, the fire traits of an atrium with an area of 310m2 with a height of 80m are predicted. In this case, it was proved that the atrium would be safe if the following conditions were met: In the event of a fire, the internal conditions of the atrium were regarded as external conditions, automatic smoke extraction was applied at the top of the atrium, and air supply at the bottom air outlet (35m2) was used. In addition, the building has a fire-resistant 1-hour aluminum atrium perimeter curtain wall and openings are fixed windows. Each floor is equipped with wire-bonded glass with a maximum height of 1.23 m.
