国家速滑馆帘布式防火分隔施工技术应用

APPLICATION OF CONSTRUCTION TECHNOLOGY FOR CURTAIN TYPE FIRE PARTITION OF NATIONAL SPEED SKATING OVAL

在建筑消防工程中,防火分隔技术分为垂直分隔技术和水平防火分隔技术两类。防火分隔的材料一般为二次结构墙、轻钢龙骨防火墙。传统的防火分隔材料为刚性材料,在复杂空间、管道密集处等部位防火分隔施工难度大,施工效果差,很难满足建筑消防要求。近年来,防火帘布作为防火分隔的材料已应用在大型场馆、商场,可以满足复杂部位的防火分隔施工。以异形结构体育馆比赛大厅与观众大厅的防火分隔为例,研究如何设计和施工才能满足该区域防火分隔的施工质量,同时对大型体育场馆、商场防火分隔设计和施工提供了新的解决思路和方法,具有先进性、创新性和极高的推广价值。

In building fire control engineering,fire partition technologies are divided into vertical fire partition technologies and horizontal fire partition technologies.Fire partitions are usually secondary structural walls and light steel keel type fire protection walls.Conventional fire partitions are made from rigid materials.Where there are complicated spatial conditions and densely distributed pipelines,fire partitions hardly meet the requirements for building fire control due to significant construction difficulties and poor construction effects.In recent years,fire curtains as fire partition materials have been widely applied in large venues and shopping malls,which cam meet the requirements for fire partitions under complicated conditions.Taking the fire partition between the competition hall and audience hall of the special-shaped gymnasium,as an example,a study was carried out on how to design and construct fire partitions in this region to meet the construction quality requirements.In addition,this paper provides a new concept and solution for the fire partition design and construction of large sports venues and shopping malls.This advanced and novel construction technology has a high value of promotion.
