1、附着升降脚手架施工组织设计附着式升降脚手架施工组织设计一、 工程概况安徽阜阳市御景城小区9#楼,位于颖川路西侧,贯清路南侧,由阜阳嘉禾置业有限公司开发而建。施工单位:河南恒宇建筑工程有限公司。监理单位:中外建天利(北京)工程监理咨询有限公司。建筑总高为104.2m,层高2.9m。地上为33层,地下为1层。建筑面积:21780。建筑物按7度抗震设防设计。建筑结构类型:框剪结构。主体的混凝土强度等级:C30。二、 编制依据(1)建筑施工工具式脚手架安全技术规范(JGJ202-2010)(2)建设施工扣件式钢管脚手架安全技术规范(JGJ1302001);(3)施工现场临时用电安全技术规范(JGJ46
2、2005);(4)建筑施工高处作业安全技术规范(JGJ80-91);(5)建筑施工安全检查标准(JGJ59-99)(6)建设工程安全生产条例;(7)施工单位提供的建筑结构图及相关说明;(8)导轨式附着升降脚手架的技术指标(企标);(9)施工现场及建筑构造要求;三、 升降脚手架设计及构造本附着式升降脚手架为主体脚手架,主体施工时,架体上升时从二层顶板至三十三层顶板标高止。3.1 平面设计升降架平面布置见平面布置图。本工程共布置机位40台,依据主体工程变形缝,分两段设置。1号机位至20号机位,为第一段。21号至40号机位,为第二段。详细布置图见附图。升降架主架宽900mm,内排立杆标准离墙距离45
3、0mm;预埋点位置见平面布置图,在结构施工时进行预埋,预埋点立面位置见预埋孔位置图。3.2 立面设计升降架提升点处立面图见立面示意图。提升点处升降架架体立面为定型加工的主框架。步高1.8m,架宽0.9m。外附着升降脚手架架体外排高度为:覆盖楼层四层半。3.3 附着式升降脚手架主要部件水平桁架、竖向主框架、承力梁、导向支座,防坠支座,花篮螺栓、钢丝绳等。3.4 提升点处竖向架体采用竖向主框架,上部采用钢管搭设;底部1.8m步高采用水平支承框架;其余架体采用483.5钢管、扣件脚手架搭设。架体中心宽度:900mm;步高1.8m;柱距不大于1.8m。3.5 提升机构预埋位置要求提升机构平面预埋点位置
4、参见附图:预埋件平面位置图。预埋孔(预埋件)位置的基本要求:采用40PVC工程塑料管作为预埋件,在埋设时应牢固、水平;并且保证预埋件中心距离尺寸为:200mm。临近两层间的垂直偏差不大于15mm,多层累积垂直偏差不大于50mm,同一点处两预留孔水平偏差不大于20mm。3.6 安全网布置要求架体外侧应采用密目式安全立网全封闭、安全网网目密度不应低于2000目100cm2,安全网要封严、绷紧、绑扎牢固。3.7 脚手板布置脚手板设计规格:厚度:40mm,宽度:两个250mm,一个300mm。架体内排向结构悬挑搭设钢管并铺设一块脚手板,保证脚手板距离墙体不大于200mm即可。所有脚手板两端用铁丝绑扎牢
5、固。脚手板应对接,接头处必须设两根横向水平杆,脚手板外伸长应取130150mm,两块脚手板外伸长度的和不应大于300mm,保证操作面平整。3.8 剪刀撑的搭设搭设外排剪刀撑时,外排剪刀撑从架体底部一直搭设至顶,剪刀撑与剪刀撑之间一定要相互平行,接头处不得少于三个旋转扣件,搭接长度不应小于1m。剪刀撑斜杆应用旋转扣件固定在与之相交的横向水平杆的伸出端或立杆上,旋转扣件中心线至主节点的距离不宜大于150mm。3.9 翻版及挡脚板在架体最底部一层脚手板与墙之间,利用脚手板、钢管、扣件制作翻板。外排架体应铺设200mm高的挡脚板。3.10 塔吊附墙与附着升降脚手架架体关系塔吊附臂与附着升降脚手架发生干
6、涉时,其附臂应尽量穿过附着升降脚手架底部的一至二步架体。此时塔吊附臂处附着升降脚手架架体利用钢管搭设,当附着升降脚手架升降时将局部钢管拆除使附着升降脚手架升降通过,附着升降脚手架升降之后立即将拆除的钢管复原安装。3.11 平台搭设要求在附着升降脚手架安装前先搭设安装平台,平台应能承受大于2KN/m2荷载。平台水平度应控制在200mm之内,平台宽度1600mm,平台内缘距墙200mm。在安装提升点处,预留安装防坠器孔洞(300mm600mm);平台外缘应设防护栏及挡脚板。3.12 升降动力系统的安装1)按设计位置编号,对承力梁进行编号;电动葫芦挂到承力梁上后,由电动葫芦向控制柜敷设电缆线,裁一小
7、块白纸写上编号用透明胶带粘在电缆线末端,电缆线末端和对应的控制柜接线端子相接。要求设计位置、承力梁、电缆线末端、控制柜接线端子四个编号必须一致。2)把控制柜顺时针和逆时针敷设过来的线分别集中在一起,捆绑后吊挂在脚手架的大横杆上,间距应不超过1.8M为宜。3)检查电动葫芦链条是否与地面垂直,不允许有反链、扭转现象,并清除链条上的污物,保持清洁,刷适量机油防锈和润滑,同时设置防护罩。4)按设计要求连接电控系统,逐台通电检查电动机旋转方向是否一致,检查电控系统是否正常,控制是否有效,同时调整同步性。5)进行整体联动升降试验,保证电控系统能够正常有效使用。6)控制柜外壳应妥善接地,不得带电移动控制柜四
