青岛中银大厦顶层屋面上部为钢桅杆，杆顶相对标高244．7m，地面至钢桅杆顶高245·8m，桅杆长49·2m，施工脚手架从钢筋检结构顶（相对标高179．8m）处搭设，搭设高度66m，为保证安全施工必须对脚手架搭设设计进行校核。1脚手架搭设设计方案脚手架钢管采用48×3．5Q235—A焊接 The upper part of the top floor of Qingdao Zhongyin Mansion is a steel boring bar with a relative elevation of 244.7m, a height of 24.8m from the ground to the top of the steel boring bar, and a 42.2m length of the boring bar. The construction scaffold is erected from the top of the bar inspection structure (with a relative elevation of 179.8m). The erection height is 66m. In order to ensure safe construction, scaffolding erection design must be checked. 1 Scaffolding erection design Scaffolding steel pipe adopts 48×3.5Q235-A welding
