中建一局四公司三里河项目经理部45楼地上外挂架施工方案
1工程概况
三里河南区危改工程东二区塔台、住宅楼工程，总面建筑积为86096.97m,2
由塔台、1住宅、2住宅、3住宅、4住宅、5住宅六大部分组成。塔台部分为全#####
现浇框架结构；住宅楼部分为全现浇剪力墙结构，抗震均为8度设防。塔台地下

二层与四周5栋高层住宅楼（15楼）连成整体，施工中设后浇带。
2施工概况
外挂架是一种三角型架的分跨、不落地的工具式脚手架。其高度为2100mm，
外挂架防护高度为4m左右（可根据楼层高度设定），悬挂在外墙穿墙拉杆上，依
靠塔吊分层提升，可以用于结构工程外墙模板施工和外墙安全防护。
本工程从地上二层开始使用外挂架。
3外墙挂架结构
1.结构由三角型架，大小横杆、立杆，安全防护拦杆，安全网，操作平台封
板，穿墙拉杆，保险螺栓，吊钩等组成。
2.三角型架，是由6.3槽钢焊接而成，架的一侧设有2个附墙支座，三角斜
撑和加强斜杆采用φ48×3.5钢管焊接，供现场安装时用十字扣件相互连接。
3.大小横杆、立杆、安全拦杆，均采用φ48×3.5钢管用十字扣件连接成整
体。
4.穿墙拉杆采用φ28圆钢制作，每个三角型架上设1根附墙支座，拉杆形
状一端为L型，另一端有M27螺纹，配M27双螺母和120×10垫片。
5.吊钩使用φ16圆钢焊接成环，每组设两个。
6.安全网从外挂架外侧顶部
