摘　　要：大空间(开间、跨度、层高较大)框架或排架结构,由于构件(指可供连墙件可靠连接的梁、柱、板等)间距较大,脚手架连墙件设置往往不能满足《建筑施工扣件式钢管脚手架安全技术规范》(JGJ130)的规定,架体侧向(横向)支座减少,造成侧向刚度减弱,在风荷载作用下,架体的侧向刚度对整个架体稳定性起着关键作用。Because of the space between two structure members（beam , column , slab etc） is large in the big space frame or bent structure building , installation of wall connecting lever for scaffolding can not be fitted for the stipulation of the technical code for safety of steel tubular scaffold with couplers in construction （JGJ130）. Reduced lateral support for scaffolding makes lateral rigidity smaller . Lateral rigidity for scaffolding plays the key role in stability of scaffolding under the effect of wind load.

关 键 词：大空间 脚手架 风荷载 稳定措施
