45、······52一、编制依据：1、工程名称 施工图,施工现场实际情况。2、建筑施工安全技术手册等国家有关规范、规程3、省市发布的有关建筑施工质量、安全文件。4、5、施工企业安全生产评价标准 （JGJ/T772003）6、建筑施工模板安全技术规程 （JGJ 1622008）7、建筑施工扣件式钢管脚手架技术规范 （JGJ 1302001）8、建设施工高处作业安全技术规范 （GB 5019493）二、工程概况工程名称 工程位于杭州市.。总建筑面积为.，其中地下建筑面积：4857，地上建筑面积：15792，地上12层，地下1层，建筑高度49.

46、6m；建筑结构为框架结构。地基基础采用筏板满堂砼基础，砼强度为C35,抗渗等级S6；地下室为框架剪力墙结构。基础顶12.850m墙柱砼强度等级为C45、（地下室墙柱抗渗等级S6）,梁板砼强度等级C35；12.85023.350m墙柱砼强度等级为C40, 梁板砼强度等级C30；23.35033.850m墙柱砼强度等级为C35, 梁板砼强度等级C30；33.850屋顶墙柱砼强度等级为C30, 梁板砼强度等级C30。砌体材料容重不大于10KN/m³,强度MU10级，用M5.0级混合砂浆砌筑，施工质量控制等级为B级；砂加气砌块强度等级A3.5,用专用砂浆砌筑。在建筑施工中，脚手架、承重支模架

47、等设施占有特别重要的地位。选择与使用合适与否，不但直接影响施工作业的顺利和安全进行，而且也关系到工程质量、施工进度和企业经济效益的提高。并根据浙江省建设厅浙建建【2003】37号文件关于加强承重支撑架施工管理的暂行规定，本项目部对承重支撑架、外脚手架等方案的编制非常重视，并严格按照该文件要求执行。三、工程结构构件模板的应用模板制作安装是本工程结构创优的关键点，在此操作过程中，不但要考虑到模板安装系统有足够的强度、刚度和稳定性，且保证位置正确，而且还要考虑拆模后砼成型的外观质量。为了实现工程结构优质的目标，本工程决定除地下室地梁、承台部分采用砖胎模和砼模外，其余采用木模板（九合板、方木制作）进行

48、施工，其支撑体系采用满堂脚手架。整个结构每层楼的柱、梁、板一起现浇，诸结构构件均采用木模进行施工。四、模板工程安装顺序1、砖胎模砖胎模在制作前，现场技术人员及时做好胎模的放线及复核工作，确保其位置准确。2、墙模、柱模墙模、柱模采用组合木模板，利用对拉螺栓拉结，外用方木、钢管支撑。剪力墙模板安装工艺流程：安装前检查安装第一步模板（两侧）安装内楞调整模板平直安装第二步至顶部两侧模板安装内楞平直安装穿墙螺杆安装外楞加斜撑并调整模板平直与柱、墙、楼板连接。柱模板安装工艺流程：搭设安装架子第一层模板安装就位检查对角线垂直和位置安装柱箍第二、三等层柱模板及柱箍安装安装梁口的柱模板对安装模板进行全面检查校正

49、群体固定。3、梁模、板模梁模采用木模、板底模采用在满堂脚手架上垫方木，而后在方木上铺木模的做法。梁模板安装工艺流程：弹出梁轴线及水平线并复核搭设梁模支架安装梁底楞及梁卡具安装梁底模板梁底起拱绑扎钢筋安装梁侧模安装另一侧梁模安装上下锁口楞、斜撑楞及腰楞和对拉螺栓复核梁模、位置与相邻模板连固。楼板模板安装工艺流程：搭设支架安装横、纵木楞调整楼板下皮标高及起拱铺设模板块检查模板上皮标高和平整度。五、模板拉接和支撑固定措施剪力墙内、外两侧模板应用对拉螺杆拉结，在外墙及水池部位，螺杆中间应加焊3厚60×60止水片。拉杆间距沿高度方向每400mm设一道，水平方向每600mm设一道为宜。内墙拉杆宜

50、做套管，以便重复利用。为保证柱观感质量，小型柱子四周模板不设对拉螺栓，但必须加密柱箍每600mm设一道。矩字柱子长边中部设一道对拉螺栓、沿竖向600布置，外加柱箍竖向600布置。梁模板在满堂脚手架基础上，再在梁两边加密支撑钢管，底模支撑在小横杆上面，侧模用短钢管及扣件来固定和加固，固定梁底模板及侧模时每根梁应拉统线，立杆不能直接支撑在楼板上，应放入垫木。现浇楼板模板承重架采用48×3.2mm扣件式钢管承重架体系间距为1200mm，水平方向不少于三道牵杆。六、节点支模做法1、梁柱节点梁柱节点支模质量的好坏是框架主体质量最为关键的一步。本工程考虑梁板和墙柱砼一起浇捣，此节点的好坏尤显重要

51、。柱模下部先立至梁底下500mm左右，上部500mm及梁侧部位采用整板留缺口，梁侧模直接在此处接出，板底与柱侧模接头出将板直接压至柱侧墙梁节点亦作此做法。七、模板支撑结构布置和力学验算为了确保承重支撑架具有足够的承载力、刚度和稳定性，能可靠地承受结构重量、侧压力等，分别对各种支撑结构进行了详细的计算。 面板的最大应力计算值 =9.883N/mm2 小于 面板的抗弯强度设计值 =13N/mm2，满足要求！面板截面的受剪应力 =0.591N/mm2 小于 面板截面抗剪强度设计值 fv=1.5N/mm2，满足要求！面板的最大挠度计算值 =1.747mm 小于 面板最大容许挠度设计值 = 1.88mm
