25、筑施工高处作业安全技术规范（JGJ80-91）；7、建筑施工安全检查标准（JGJ59-2011）8、河南省和漯河市的相关地方标准和要求二、工程概况漯河天翼星公馆工程主楼为剪力墙结构，地下一层为框架结构；地上部分由三栋主楼（1#2#3#楼）和商业组成；地下由地下车库相连（商业除外）。主体高度81.70M；总建筑面积39085.58m2(其中地上建筑面积33362.04 m2,地下建筑面积5723.54 m2)；结构0.00相当于绝对标高61.9M，室内外高差0.30M.基础形式为CFG桩+抗水底板.主楼以外筏板基础局部增设下柱墩。本工程建筑抗震设防类别为丙类，抗震烈度为6度，设计地震分组为第一组

26、，结构使用年限50年。结构安全等级为二级，基础设计等级为甲级，建筑场地类别为三类，框架一区的抗震等级为三级，抗震构造措施按抗震等级三级执行，二区抗震等级为四级，抗震构造措施按抗震等级四级执行.三、总体策划结合本工程结构形式、实际施工特点，结合建筑面积，每栋楼采用一部施工电梯，满足施工现场的需求。本工程地下室只有一层，考虑上人和上料的方便，考虑在地下室顶板上支设施工电梯。本工程的地下室为人防工程顶板为250厚，C40P6混凝土，配筋为双层双向三级直径12150。地下室平时为停车库，战时为人防，地下室基础采用整体式防水筏板。顶板设计活荷载为20KN/m2，建筑安全等级为二级。施工电梯经设备采用SC

27、D200/200型施工升降机，该升降机是一种采用齿轮、齿条驱动方式的垂直运输机械。并较其它提升机械具有性能稳定，安全可靠，不另设机房、井道，拆装方便等特点。本工程采用升降机标准产品导架高度为90米。主要参数：每只吊笼额定载重量2T，额定安装重量1T，安装吊杆额定其重量200kg，吊笼净尺寸为3*1.3*2.2m，最大提升高度为151m（本工程为81.5米），额定提升速度为34.4m/min。防坠安全器制动力矩大于3000N.m，动作速度为51.6m/min，标准节规格立柱管中心距为0.65*0.65，高度为1.508m，（本工程采用55个标准节）围栏重量为1170kg，每只吊笼重量（包括传动机

28、构）为1300kg。四、基础设计及加固1、荷载合计 荷载重量 围栏重量：1170kg吊笼重量：1300*22600吊笼载重量2000*24000导架总重量：191*6011460以上五项重量合计：19230kg 附墙架、动力电缆、电缆导向装置、钢丝绳、头架紧固件等重量约占导架重量的30=3438kg 用过道竖杆和过桥连杆的附墙结构的重量增加约为导架总重量的45=5157kg，以上合计静载合计27825kg，考虑在施工过程中的动荷载约为静荷载的2倍。所以基础所承受最大的荷载值为55650kg 结构需要承受的力为55650*9.8kg545KN 2、基础加固本工程施工电梯直接放置在地下室顶板上，考

29、虑顶板自身所承受的荷载值不能满足施工电梯的荷载值，需要用顶板进行加固。（1）基础的尺寸为6700*4700mm见附图：（2）在混凝土上搭设立杆，立杆间距为1000*1000，水平杆为1000mm，扫地杆离地200mm，立杆下部垫上方木，立杆上部全部采用顶托，顶托内必须放置钢管且钢管不得偏离中心10mm。（3）沿立杆四周必须搭设一圈封闭的剪刀撑。剪刀撑与立杆采用旋转扣件牢固连接。3、施工电梯基础直接放置顶板上，顶板地脚加固：在顶板上放100*100*8的钢板，四角并采用M25螺栓进行固定。钢板上放置外径直径50高100的套筒，直径采用M30-深70。施工电梯标准节采用M30地脚螺栓与基础固定。预

30、埋地架，标准节下面四角地脚采用地架进行连接一起。长边采用L75*50*6-910的角铁，短边采用L75*50*6-330的角铁，中间对角线采用L75*50*6-985的角铁一道，各种零件材料之间均采用连接焊连接。五、外防护施工电梯入料口采用双排单立杆架进行防护，并安设防护门。第一排立杆紧靠建筑物外挑檐，第二排立杆处在建筑物边梁内侧，与第一排立杆间距600mm，第一道水平杆2.1m，上下加设一道水平杆。在楼层处上下设置小横杆，与建筑物可靠的连接。立杆未经许可，任何人不得进行拆除。见附图：入料口向两侧安设建筑物临边防护架，与入料口的第一排立杆相连接。临边除防护门外，必须采用密目式安全网进行封闭。入

31、料口与建筑物之间的缝隙处必须采用木板进行固定在楼层的小横杆上，用22#铁丝扎牢。外立杆应刷成黄色，电梯防护门作好安全标语以及楼层号并采用22#铁丝与防护门牢固绑扎。电梯防护门都刷成黄色漆。见附图。六、安装和拆除方案见单独方案。七、安全通道施工电梯前室必须搭设牢固的安全通道。挑空两根立杆、跨越三步三跨，大小为4.5m4.5m（宽高）。出入口处再搭设6.0m4.5m6.0m （长宽高）的防护棚，上铺5cm厚的双层脚手板，具体见下图。在出入口两侧的内、外排单立杆处分别增设一根辅立杆，并高于门洞口一步，立柱用短管斜撑相互联系。上方悬空双排架立柱处各增加一根斜杆，斜杆与各主节点相交处用扣件固定。洞口上方

32、增设两道横向支撑，应伸出斜腹杆的端部，以保证立柱悬空处的整体性。门洞两侧分别增加两根斜腹杆，并用旋转扣件固定在与之相交的小横杆的伸出端上，旋转扣件中心线至主节点的距离在15cm内。当斜腹杆在1跨内跨越2个步距时，应在相交的大横杆处增设一根小横杆，将斜腹杆固定在其伸出端上；斜腹杆宜采用通长杆件，必须接长时用对接扣件连接。增设门洞处上升斜杆、平行弦杆桁架示意详见下图。施工电梯加固计算书支架的计算依据建筑施工扣件式钢管脚手架安全技术规范（JGJ130-2011）、混凝土结构设计规范GB50010-2010、建筑结构荷载规范(GB 50009-2012)、钢结构设计规范(GB 50017-2003)等

33、规范编制。一、参数信息:1.支架参数横向间距或排距(m):1；纵距(m):1；步距(m):1.00；立杆上端伸出至模板支撑点长度(m):0.30；模板支架搭设高度(m):3.65；采用的钢管(mm):483.5 ；板底支撑连接方式:钢管支撑；立杆承重连接方式:可调托座；板底钢管的间隔距离(mm):1000；板底支撑采用钢管支架。托梁材料为：钢管(双钢管) :48 3.5；2.荷载参数施工均布荷载标准值(kN/m2):1.000；结构需要承受的力为545KN，折合面荷载545（6.24.2）20.93KN/m2，楼板自身所承受的荷载为20 KN/m2，则加固支撑架所承受的面荷载为0.93KN/m

34、2。取单位宽度1m的面板作为计算单元 图2 支撑架荷载计算单元二、纵向支撑钢管的计算:纵向钢管按照均布荷载下连续梁计算，截面力学参数为截面抵抗矩 w=5.08cm3；截面惯性矩 I=12.19cm4； 计算简图1.荷载的计算：(1)q10.9310.93 KN/m (2)活荷载q2 = 11 =1 kN/m；2.强度验算:最大弯矩考虑为三跨连续梁均布荷载作用下的弯矩。最大弯矩考虑为静荷载与活荷载的计算值最不利分配的弯矩和，计算公式如下:最大弯矩计算公式如下: 静荷载：q1 = 1.2 0.93= 1.11kN/m；活荷载：q2 = 1.41= 1.4 kN/m；最大弯距 Mmax = (0.1

35、1.11+0.1171.4 ) 0.62 = 0.099 kN.M； 最大支座力 N = ( 1.1 1.11+ 1.21.4)0.6 = 1.74 kN ；最大应力计算值 = M / W =0.2345106/5080 = 46.1 N/mm2； 纵向钢管的抗压强度设计值 f=205.0 N/mm2；纵向钢管的最大应力计算值为 46.1 N/mm2小于 纵向钢管的抗压强度设计值 205.0 N/mm2,满足要求!3.挠度验算:最大挠度考虑为三跨连续梁均布荷载作用下的挠度计算公式如下: 静荷载 q1 =14.18 kN/m活荷载 q2 = 1 kN/m三跨连续梁均布荷载作用下的最大挠度V= (

36、0.6777.662+0.9900.6)6004/( 10020.610812.19 ) =0.5 mm；支撑钢管的最大挠度小于1000/150与10 mm,满足要求!三、托梁材料计算:托梁按照集中荷载作用下的三跨连续梁计算；托梁采用：钢管(双钢管) :48 3.5；W=10.16 cm3；I=24.38 cm4；集中荷载P取纵向板底支撑传递力，P = 6.673 kN； 此集中力直接传递到顶托材料上，由顶托向下作用与立杆上，所以托梁材料本身的强度和变形满足要求。四、模板支架立杆荷载标准值(轴力):作用于模板支架的荷载包括静荷载和活荷载。1.静荷载标准值包括以下内容：静荷载标准值 NG = 1

37、4.1811 = 14.18 kN；2.活荷载为施工荷载活荷载标准值 NQ = 111 = 1 kN；3.立杆的轴向压力设计值计算公式 N = 1.2NG + 1.4NQ = 18.416kN；五、立杆的稳定性计算:立杆的稳定性计算公式 其中 N - 立杆的轴心压力设计值(kN) ：N = 18.416kN； - 轴心受压立杆的稳定系数,由长细比 Lo/i 查表得到； i - 计算立杆的截面回转半径(cm) ：i = 1.58 cm； A - 立杆净截面面积(cm2)：A = 4.89 cm2； W - 立杆净截面模量(抵抗矩)(cm3)：W=5.08 cm3； - 钢管立杆受压应力计算值 (

38、N/mm2)； f- 钢管立杆抗压强度设计值 ：f =205 N/mm2； L0- 计算长度 (m)；如果完全参照扣件式规范，由下式计算： l0 = h+2a a - 立杆上端伸出顶层横杆中心线至模板支撑点的长度；a = 0.3 m；得到计算结果：立杆计算长度 L0 = h + 2a = 1+20.3 = 1.6 m ；L0 / i = 1600 / 15.8=101 ；由长细比 lo/i 的结果查表得到轴心受压立杆的稳定系数= 0.58 ；钢管立杆受压应力计算值；=18416/(0.58489) = 64.93 N/mm2；立杆稳定性计算 = 64.93 N/mm2 小于 钢管立杆抗压强度设

39、计值 f= 205 N/mm2，满足要求！消火栓给水系统和自动喷淋给水系统由设在地下二层的消火栓给水泵和自动喷淋给水泵经消防水池到消防给水泵，再向大楼各层消火栓和喷淋管网供水。同时消火栓给水系统和自动喷淋给水系统管网均与屋顶设置的生活、消防共用水箱相连、并通过屋顶设置的消防稳压设备进行稳压。improve, security prevention capacity obviously enhanced, security hidden and security accident obviously reduced, effective guarantees information health
