和屋顶机房夹层,高度为２6６.2０m,地下4层，高度为19.30m,S２核心筒总高度为2８５.5０ｍ。标准层高度为３．8０m,模板配置为３.95ｍ。模板配置:为防止浇筑漏浆,每次浇筑时模板下包５０mｍ,上包１０0ｍｍ,以达到安全施工,顺利浇筑混凝土的效果。但在Ｓ1、Ｓ2核心筒浇注时，有非标层高度大于标准层高度时,在浇注高度大于标准层高度不超过1.０m时,可采用模板上部配备加高节经行浇注，在高度大于１.０m时,该层分两次浇注,具体尺寸见详图~架体配置:根据工程特点,为保安全、加快施工速度及施工质量，该工程采用ＳCS-8０液压自爬模架体。架体特征:当SＣS-８０架体组拼完成,进入标准爬升是无需塔吊等额外的提升配置,该架体爬升速度快，爬升过程安全，可缩短工程施工工期,从而达到降低成本，安全完成施工的效果。3．2平面模板的组成模板刚度大,接长和接高均很方便,模板最高可一次浇筑十米以上。四爬模主要性能指标4.1液压自爬模板体系的优点:１．液压爬模可整体爬升，也可单榀爬升，爬升稳定性好。2.操作方便,安全性高，可节省大量工时和材料。3.除了因为建筑结构的要求(如墙面突然缩进或形状突变)需要对模架改造之外,一般情况下爬模架一次组装后，一直到顶不落地，节省了施工场地，而且减少了模板(特别是面板)的碰伤损毁。４.液压爬升过程平稳、同步、安全。5．提供全方位的操作平台,施工单位不必为重新搭设操作平台而浪费材料和劳动力。6．结构施工误差小,纠偏简单，施工误差可逐层消除。7.爬升速度快，可以提高工程施工速度(平均四天一层),最快的可达到２．5天。8（模板自爬,原地清理,大大降低塔吊的吊次。五工艺原理自爬模的顶升运动通过液压油缸对导轨和爬架交替顶升来实现。导轨和爬模架互不关联,二者之间可进行相对运动。当爬模架工作时，导轨和爬模架都支撑在埋件支座上，第5页共1０页南京道广建筑模板有限公司大连中心裕景（公建）两者之间无相对运动。退模后立即在退模留下的爬锥上安装受力螺栓、挂座体、及埋件支座,调整上、下换向盒棘爪方向来顶升导轨,待导轨顶升到位,就位于该埋件支座上后,操作人员立即转到下平台拆除导轨提升后露出的位于下平台处的埋件支座、爬锥等。在解除爬模架上所有拉结之后就可以开始顶升爬模架，这时候导轨保持不动,调整上下棘爪方向后启动油缸，爬模架就相对于导轨运动，通过导轨和爬模架这种交替附墙,互为提升对方,爬模架即可沿着墙体上预留爬锥逐层提升。六液压自爬模构造液压自爬模板体系的爬升系统主要包括:预埋件部份、导轨部份、液压系统组成。6.１埋件总成液压自爬模体系的埋件总成包括:埋件板、高强螺杆、爬锥、受力螺栓和埋件支座等。6.1.1埋件板与高强螺杆埋件板与高强螺杆连接,能使埋件具有很好的抗拉效果,同时也起到省料和节省空间的作用，因为其体积小,免去了在支模时埋件碰钢筋的问题。埋件板大小、拉杆长度及直径须按抗剪和抗拉设计计算确定。6.1.2爬锥、安装螺栓爬锥和安装螺栓用于埋件板和高强螺杆的定位,砼浇筑前，爬锥通过安装螺栓固定在面板上。6.２受力螺栓受力螺栓是锚定总成部件中的主要受力部件，要求经过调质处理(达到Rc25-30),并且经过探伤,确定无热处理裂纹和其他原始裂纹后才允许发货。６．３埋件支座埋件支座连接导轨和主梁,它受到施工活荷载、重力荷载、风荷载等荷载的联合作用,具有强的抗垂直力、水平力和弯矩作用。6.４导轨导轨是整个爬模系统的爬升轨道，它由由工字钢１6及一组梯档（梯档数量依浇筑高第6页共1０页南京道广建筑模板有限公司大连中心裕景(公建)度而定)组焊而成,梯档间距22５mm，供上下轭的棘爪将载荷传递到导轨，进而传递到埋件系统上。６.5液压爬升系统如下图所示,液压爬升系统包括:液压泵、油缸、上、下换向盒四部分。6．５.1液压泵和油缸液压泵和油缸向整个爬模系统提供升降动力。6.5．2上、下换向盒上、下换向盒，是爬架与导轨之间进行力传递的重要部件,改变换向盒的棘爪方向,实现提升爬架或导轨的功能转换。七爬模安装７.１爬模安装爬升流程混凝土浇筑完后?拆模后移?安装附装置?提升导轨?爬升架体?绑扎钢筋?模板清理刷脱模剂?埋件固定模板上?合模?浇筑混凝土预埋件安装预埋件安装,
