根据规定,脚手架必须设置纵、横向扫地杆。纵向扫地杆应采用直角扣件固定在距钢管底端不大于200mm处的立杆上。横向扫地杆应采用直角扣件固定在紧靠纵向扫地杆下方的立杆上。脚手架是建筑施工中不可缺少的临时设施。它是为解决在建筑物高部位施工而专门搭设的操作平台,用于施工作业和运输通道,临时堆放施工材料和机具。因此,脚手架在砌筑工程、混凝土工程、装修工程中有着广泛的应用。脚手架的主要作用 1)可以使操作人员在不同部位进行施工操作; 2)按规定要求在脚手架上堆放建筑材料; 3)进行短距离的水平运输; 4)保证施工作业人员在高处作业时的安全。请参考下面的中英文对照:满堂脚手架的立杆间距1.2m,横杆间距为1.6m。每隔12m设置一道剪力撑。搭设方法见下图。立杆与纵、横向扫地杆连接固定,纵横向立杆应在同一条直线;纵、横杆搭接接头不要大于50%,即杆件接头要错位搭接。立杆搭设时应通过吊垂线保证其垂直度,垂直误差不得大于20mm。spacing between poles of full scaffold is 1.2m, and set cross bridging for every 12m, and method please see following sketch. poles shall be erected as per the location, and fasten the poles with longitudinal and transverse bottom pole, and longitudinal and transverse poles shall be at the same straight line. overlap junctions of longitudinal and transverse poles shall be not more than 50%, that is, pole junctions shall be overlapped staggered. verticality shall be ensured by plumb line when, and tolerance of verticality shall be not more than 20mm.
