建筑施工附着升降脚手架是适应高层建筑,特别是超高层建筑施工需要的新型脚手架,在使用中确定脚手架的风荷载计算方法是一项首要和迫切的任务。为此,提出系统完整的附着升降脚手架的风荷载计算方法,给出基于风洞实验的附着升降脚手架风载体型系数值表格以及脚手架在爬升阶段和下降阶段的风振系数实用计算公式和相关查用表格,并对附着升降脚手架动力特性的计算进行了讨论,使这种新型脚手架的风荷载计算有了工程上的可操作性。
The construction scaffolding is a new type of scaffolding that is suitable for the construction of high-rise buildings, especially for the construction of super high-rise buildings. Determining the wind load of scaffolding in use is a primary and urgent task. Therefore, the calculation method of the wind load of the attached elevator frame with scaffolding is put forward. The formula of wind-induced body coefficient of attached lifting scaffold based on the wind tunnel experiment and the practical calculation formula of the wind-induced vibration coefficient of the scaffolding in the climbing phase and the descending phase are given. The form and the calculation of the dynamic characteristics of the attached lifting scaffolding are discussed to make the calculation of the wind load of the new scaffolding technically feasible.
