武汉研发高楼逃生黑科技!40米高空降落仅需26秒(图)

2017-06-20 16:35:30   长江日报融媒体

长江日报融媒体6月20日消息,伦敦高层住宅火灾事件还在“发酵”,高层建筑的逃生问题也引发思考。这一难题或在中国破解。
磁力缓降高楼逃生装置在汉试验成功

近日,在建的中国第一高楼、世界第二高楼——武汉636米的绿地中心高楼旁的在建公寓楼外墙上,体重80公斤的试验人员利用依附于建筑外墙的逃生轨道,从高楼40米处以1.5米/秒的速度下降,用时26秒安全抵达地面,标志着中建三局工程技术研究院历时两年研发的磁力缓降高楼安全逃生装置试验成功。

20日上午,记者在高楼40米处看到,技术人员身绑安全带,双手握住逃生装置的两个把手,装置在导轨上立即锁死,人悬挂式沿导轨匀速下降。

这一逃生装置具有多重优点:无需电能,依靠磁力实现匀速下滑;操作简单,无需专业培训;导轨依附建筑物架设,逃生高度不受限制;可在任意楼层进入,下降速度可调、可控,逃生效率高。

磁力缓降逃生装置演示

中建三局工程技术研究院高新技术应用研究所副所长刘志茂介绍,磁力缓降装置的技术原理是根据楞次定律进行开发设计,由内设高强磁铁的载人装置与非铁磁性逃生轨道组成,导轨与建筑外墙平行,垂直于地面,是铝管材料。紧急情况下,涉险人员借助载人装置通过轨道以平稳、安全的速度进行逃生。

武汉绿地中心位于武昌滨江商务区,主楼目前已突破450米,全部建成后,为地上120层,高度将达到636米,该楼的安全问题也备受瞩目,是否今后可通过这一装置让人从数百米高度安全降下?

单次最高承重120公斤

中建三局相关技术人员介绍,目前的试验高度最高为7层楼40米,理论上说,不受高度限制,只要有安装空间,600米也可以。接下来,还会在不同高度试验,进一步论证。经试验,装置最重能承受120公斤的人或物。
