1、2.8m附着升降脚手架设计摘要附着升降脚手架是搭设一定高度的外脚手架，并将其附着在建筑物上，脚手架本身安装有升降机构和升降动力设备，随着工程的施工进度，脚手架沿建筑物高度方向升降，以满足操作层的安全防护作用。附着升降脚手架作为高层建筑用施工设备，适用于剪力墙、框架结构等高层建筑、外墙及装修防护用脚手架，该设备是一种复杂的成套施工设备，它包括控制电路及环链电动葫芦、爬升机构、安全机构、竖向主框架和水平行架。升降脚手架是分跨、不落地的工具型脚手架，按照楼层的边围的尺寸大小由对应数量的升降单元体构成，附着在墙上。由于附着升降脚手架采用相互爬升来实现提升，因此此脚手架相对其他脚手架耗用材料少
2、，要求电动升降人工少，整体升降安全、速度快。本设计由一跨独立的单元体为设计对象。附着升降脚手架的设计主要是对结构以及材料的设计，以及对各部分的受力计算、材料强度的校核，设计中还要考虑外在因素的影响，包括风载荷、施工载荷。关键词：脚手架强度载荷稳定性2.8m附着升降脚手架设计ABSTRACTThescaffoldisaoutsidescaffoldwhichtakestoestablishcertainheight,combinetoadheretoitonthebuilding,thescaffoldgearinghasriseandfallorganizationandmotive
