１工程概况

本工程为框架结构,标准层,建筑高度m,建筑面积m２、

本工程楼体外墙采用无机硅酸盐水泥泡沫保温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,涂料饰面得外墙保温系统。

２材料组成?

2、１无机硅酸盐水泥泡沫保温板规格为12０0ｍｍ×600mm×６０mm,平头式,阻燃型,表观密度25～32kｇ/ｍ3,尺寸收缩率小于1、5%,吸水率小于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:聚合物砂浆等于1:5,可操作时间不小于2h。

2、3固定件

采用自攻螺栓配合工程塑料膨胀钉固定无机硅酸盐水泥泡沫保温板,要求单个固定件得抗拉承载力标准值不小于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4mｍ×４mm,宽度10００mｍ,每卷长度100m。

２。5聚乙烯泡沫塑料棒

用于填塞膨胀缝,作为密封膏得隔离背衬材料,其直径按照缝宽得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得墙面、

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、?４施工工具

电热丝切割器或壁纸刀(裁保温板及网格布用)、电锤(拧胀钉螺钉及打膨胀锚固件孔用)、根部带切割刀片得冲击钻钻头(为放固定件打眼用,切割刀片得大小、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)、其她抹灰专用工具、

?5工艺流程?5、１基层清理

5。1.1清理墙面上残留得浮灰、脱模剂油污等杂物及抹灰空鼓部位等、

5.1。2剔除接槎处劈裂得混凝土块、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要求粘贴保温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
