铁路客站高大空间装饰吊顶施工技术研究

RESEARCH ON CONSTRUCTION TECHNIQUE OF DECORATIVE SUSPENDED CEILING IN HIGH AND LARGE SPACE OF RAILWAY STATION

铁路客站具有空间大、高度高的建设特点,通过对比分析大跨度网架结构铝条板吊顶体系、大跨度弧形钢桁架结构铝条板吊顶、单曲波浪形网架结构铝条板吊顶、新型夹片式铝条板吊顶支撑体系及各种施工平台应用技术,得出:大跨度钢结构吊顶一般设吊顶转换支承架体系;转换架结构应进行专项设计和计算;多数设有转换层的高大空间吊顶适用无脚手架施工技术。

Railway station is large and high. After analysis and comparison among different suspended ceiling systems, such as aluminium batten suspended ceiling system under large-span grid structure, aluminum batten suspended ceiling system under large-span arch steel truss structure, aluminum batten suspended ceiling system under single-curve wave grid structure, new clamp-type aluminum batten suspended ceiling supporting system and application techniques of various construction platforms, it is found that suspended ceiling transition supporting frame system shall usually be set for construction of suspended ceiling under large-span steel structure; special design and calculation shall be carried out for the transition supporting frame;scaffold-free construction technique is usually applicable to suspended ceiling with transition floor in large and high space.
