摘要
北京绿地中心工程建筑高度260 m,结构形式复杂,外框架为劲性框架柱及悬挑楼承板。工程选用爬架体系,针对工程钢结构焊接量大、高空防火及安全隐患大的特点,采取了一系列防火及防高处坠落措施,如钢丝网片及铁皮防护措施,悬挑楼承板创新使用可拆卸式角钢支撑,最大限度地降低了超高层施工的安全隐患。
The 260m-high Beijing Greenland Center has complex structural shape and its outside frame is made of rigid frame column and cantilever floor deck, so climbing scaffold system was used. Considering the huge workload of steel structure welding and potential fire and safety risks at high altitude, a series of fire and dropping prevention measures were adopted, such as protection by steel fabric sheet and iron sheet, etc., and removable angle steel support was innovatively used on cantilever floor deck, to maximally reduce the safety risk in construction of super-high building.
