1.编制依据
1.１十二院城一期工程施工组织总设计
1。2十二院城一期工程施工图纸
１.3建筑地基基础工程施工质量验收规范GB５02０2-2０02
1.4建筑机械使用安全技术规程JGJ33—2001
1。5SC系列施工升降机安装说明书
2.分项工程概况
十二院城一期工程A１栋高层住宅工程，结构形式为剪力墙结构,抗震等级一级，设防烈度8度,主体３4层，建筑物总高度98.6ｍ.
主体结构及装修阶段施工时，垂直运输机械采用SCD２0０/２00施工升降机一台配合施工，计划安装时间为结构1４层开始.根据施工现场的场地情况及建筑物的平面位置,确定施工升降机安装于建筑物南侧3~5轴之间，中心距A轴４500ｍm，升降机安装高度为106。5ｍ（-1。６0０～98.6m，计71节标准节)。基础平面尺寸为36０0×450０ｍm,在地下二层顶板上做３00mm厚C30混凝土基础,基础四周砌240厚砌体高400ｍm。顶板压力达到3０ｍpa的要求。
由于升降机基础位于地下二层结构顶板上,并有沉降后浇带从基础中通过，该部位沉降后浇带提前浇筑混凝土，根据荷载要求对升降机及进料平台采用φ48*3。５钢管进行加固，不考虑结构板受力.
３.基础设计荷载取值
施工升降机自重:安全系数K=2。1，SＣＤ2０0/200型施工升降机按高度106.5m时的重量:P1=(吊笼重+外笼重+导轨架总重+对重重+载重量)×2.1。吊笼重32ＫN，外笼重1６KN,导轨架总重=(每节重1.61ＫN,每节高1。5０8m)１.61ＫN×７1节=１1４.３１KN,载重4０KN，对重32KN。Ｐ１＝（32
