第2章工程概况
本工程总用地面积 m2，其中占地面积 m2，工程性质为办公楼、**及地下停车库。设计为一类高层公共建筑，使用年限50年，耐火等级一级；建筑由栋层办公楼，层**裙房及地下层地下室构成，总建筑面积 m2，总建筑高度米。
本工程共有28个电梯井，其中有2个电梯井位于地下室，6个电梯井位于裙楼区域内，20个电梯井位于主塔楼核心筒内，各部位电梯井的具体情况详见下表。
根据本工程的结构特点，对裙楼区域内的电梯1-DT1、1-DT2、1-DT5、1-DT6、1-DT7、1-DT8、1-DT9、1-DT10以及主塔楼区域内的电梯1-DT3、1-DT4井筒内采用落地式钢管脚手架搭设架体，钢管立杆落在电梯基坑底标高上。主塔楼区域内的1-TDT1～1-TDT16和1-TXFDT1、1-TXFDT2井筒内架子防护采用钢管脚手架和工字钢分段来挑设。核心筒中电梯井筒高度十分高，为了保证在现场施工中工人施工安全能得到有效保障，特编制此方案。
第3章施工准备

（3）制作平台前应对进场的材料及进行严格检查，符合要求后才能使用。
2人员准备
本工程配置专业焊工3人、架子工10人，工长及技术人员各1人。
第4章电梯井架体防护的搭设
1材料选用及要求
（1）脚手架采用扣件式钢管脚手架体系，钢管搭设选用Ф48×3.5mm普通钢管，每根钢管的最大重量不得大于25kg。
（2）采用直角扣件、旋转扣件、对接扣件连接，其材质应符合现行国家标准《钢管脚手架扣件》（GB15831）的规定，并经安全员和材料员外观检测合格并签字同意后方可进场，否则不得使用。
（3）有裂缝或者锈蚀的、焊接的等不符合标准的钢管严禁使用。有脆裂、变形、滑丝的等不符合标准的扣件禁止使用。钢管上严禁打孔。
（4）型钢采用20号工字钢。
2电梯井筒内落地架的搭设要求
