挤塑聚苯乙烯泡沫板外墙保温施工方案
1 工程概况
沈阳克莱斯特国际外商公寓工程位于沈阳市皇姑区黄河南大街38号，占地面积76000平方米，是由十个高层建筑和一个多层建筑组成的高层商、住楼群。工程总建筑面积365000m2。
本工程高层楼体外墙采用挤塑聚苯乙烯泡沫板为主要保温隔热材料，以粘、钉结合方式与墙身固定，抗裂砂浆复合耐碱玻纤网格布为保护增强层，涂料饰面的外墙保温系统。下面以最早封顶的9#楼为例，编制外墙保温施工方案。
2 材料组成
2．1挤塑聚苯乙烯泡沫板
规格为1200×600×40，平头式，阻燃型，表观密度25—32kg/m3，尺寸收缩率＜1.5%，吸水率＜1.5%。 2．2专用聚合物粘结、面层砂浆
厂家已配制好，现场施工时加水用手持式电动搅拌机搅拌，重量比为水:聚合物砂浆=1:5，可操作时间不小于2h。 2．3固定件
采用自攻螺丝配合工程塑料膨胀钉固定挤塑聚苯乙烯泡沫板，要求单个固定件的抗拉承载力标准值≥0.6KN。 2．4耐碱玻纤网格布
用于增强保护层抗裂及整体性；孔径4×4，宽度1000，每卷长度100000。 2．5聚乙烯泡沫塑料棒
用于填塞膨胀缝，作为密封膏的隔离背衬材料，其直径按照缝宽的1.4倍选用。
3 施工要求及条件
3．1经业主、监理、总包、外保温施工单位联合验收的9#楼外墙体（可分段进
行）垂直、平整度满足规范要求，门窗框安装到位，飘窗、阳台栏板、挑檐等突出墙面部位尺寸合格，办理交接单后即可进行施工。
3．2雨天施工时，须采取有效防雨措施，防止雨水冲刷刚施工完但粘结砂浆或面层聚合物砂浆尚未初凝的墙面。
3．3施工现场环境温度及找平层表面温度在施工中及施工后24h内均不得低于5℃，风力不大于5级。
3．4外墙保温伸缩缝沿建筑物高度每六层设置一道，即在6层、12层、18层、24层的大墙面设10mm宽水平分格缝，飘窗及阳台处不设；具体设置位置为：分格缝的上口与该层飘窗窗台底面保温层的底面等标高。
4 施工工具
电热丝切割器或壁纸刀（裁挤塑板及网格布用）、电锤（拧胀钉螺丝用及打膨胀锚固件孔用）、根部带切割刀片的冲击钻钻头（为放固定件打眼用，切割刀片的大小、切入深度与膨胀钉头一致）、手持式电动搅拌器（搅拌砂浆用）、木锉或粗砂纸（打磨用）、其它抹灰专用工具。
5 工艺流程
基层清理 预粘板边翻包网格布 刷专用界面剂 粘贴挤塑板 中间验收 抹底层聚合物砂浆 配专用聚合物粘结砂钻孔安装固定件 拌制面层聚合物砂浆 粘贴网格布 挤塑板打磨、找平、清洁 刷一遍专用界面剂 抹面层聚合物抗裂砂浆 分格缝内填塞内衬、封密封胶 验收 5．1基层清理 5．1．1清理砼墙面上残留的浮灰、脱模剂油污等杂物及抹灰空鼓部位等。
5．1．2剔除剪力墙接茬处劈裂的砼块、夹杂物、空鼓等，并重新进行修补；窗台挑檐按照2%用水泥砂浆找坡，外墙各种洞口填塞密实。
5．1．3要求粘贴挤素板表面平整度偏差不超过4mm，超差时对突出墙面处进行打磨，对凹进部位进行找补（需找补厚度超过6mm时用1：2.5水泥砂浆抹灰，需找补厚度小于6mm时由保温施工单位用聚合物粘结砂浆实施找补）；以确保整个墙面的平整度在4mm内，阴阳角方正、上下通顺。 5．2配制砂浆
5．2．1施工使用的砂浆分为专用粘结砂浆及面层聚合物抗裂砂浆。
5．2．2施工时用手持式电动搅拌机搅拌，拌制的粘结砂浆重量比为水:砂浆=1:5，边加水边搅拌；搅拌时间不少于5分钟，搅拌必须充分、均匀，稠度适中，并有一定粘度。
5．2．3砂浆调制完毕后，须静置5分钟，使用前再次进行搅拌，拌制好的砂浆应在1h内用完。 5．3刷专用界面剂一道
为增强挤塑板与粘结砂浆的结合力，在粘贴挤塑板前，在挤塑板粘贴面薄薄涂刷一道专用界面剂；待界面剂晾干后方可涂抹聚合物粘结砂浆进行墙面粘贴施工。
5．4预粘板端翻包网格布
在飘窗板、挑檐、阳台、伸缩缝等位置预先粘贴板边翻包网格布，将不小于220mm宽的网格布中的80mm宽用专用粘结砂浆牢固粘贴在基面上（粘结砂浆厚度不得超过2mm），后期粘贴挤塑板时再将剩余网格布翻包过来，做法及尺寸见后图。 5．5粘贴挤塑板
5．5．1施工前，根据9#楼整个外墙立面的设计尺寸编制挤塑板的排板图，以达
