30、工程施工组织设计。2.工程概况1.本工程位于位于*大道旁。建筑高度为30.35m；地下1层，层高3.9m；地上7层，首层层高4.20m，二层层高3.60m,三至七层层高均为3.20m；结构形式为框架结构,基础类型为独立基础。根据本工程实际情况，外脚手架形式采用落地式双排钢管脚手架，搭设高度32m,外架搭设严格按照现行建筑施工扣件式脚手架安全技术规范（JGJ 130-2011年修订版）搭设。3.施工部署3.1.组织机构外架搭设由工长负责组织实施，其他人员配合。外架所需材料、劳动力计划均由外架工长负责编制，材料员、劳资员负责组织进场。技术交底工作由工长负责。3.2.设计总体思路 根据工程特点，采用
31、落地式双排钢管脚手架，架体在主体阶段主要用于安全防护，装修阶段既用于装修施工，也兼作安全防护。3.3.劳动力准备搭设阶段共需架子工8名，维护阶段共需架子工2名，拆除阶段共需外架工15名。所有架子工均需持证上岗。架子工由劳务公司提供。搭设阶段安排2名测量放线工配合。3.4.材料准备 所有钢管质量应符合碳素结构钢（GB/T700）中Q235-A级钢的规定，及直缝电焊钢管（GB/T 13793）、低压流体输送焊接钢管（GB/T 3092），并有产品出厂合格证。扣件采用可锻铸铁制作的扣件，其质量应符合国家标准钢管脚手架扣件（GB15831）的规定，并有出厂合格证。扣件在螺栓拧紧扭矩达65Nm时，不得发
32、生破坏。 脚手架配件数量匡算: 扣件式钢管脚手架的杆件配备数量需要一定的富余量，以适应构架时变化需要，因此按匡算方式来计算；根据脚手架立杆数量按以下公式进行计算： L -长杆总长度(m)； N1 -小横杆数(根)； N2 -直角扣件数(个)； N3 -对接扣件数(个)； N4 -旋转扣件数(个)； S -脚手板面积(m2)； n -立杆总数(根) n=210； H -搭设高度(m) H=32； h -步距(m) h=1.8； la-立杆纵距(m) la=1.6； lb -立杆横距(m) lb=0.80； 长杆总长度(m) L =1.1 32(210 + 1.60 210/1.80 - 21.6
33、0/1.80)=13900； 小横杆数(根) N1 =1.1 (32 /1.80 2 + 1) 210 = 2285；直角扣件数(个) N2 =2.2 (32/ 1.80 + 1) 210 = 8676；对接扣件数(个) N3 =13900/ 6.00 = 2317；旋转扣件数(个) N4 =0.3 13900/ 6.00 = 696；脚手板面积(m2) S = 1.1 ( 210-2) 1.60 0.80=292.86。根据以上公式计算得长杆总长13900m；小横杆2285根；直角扣件8676个；对接扣件2317个；旋转扣件696个；脚手板292.86m2。3.5.机具准备搭、拆架子所需机具
