17、符合基层墙体找平层抹灰结束后允许偏差之要求。2.粘贴保温板2.1制线、挂基准线; 弹控制线:根据建筑立面设计和外墙外保温技术要求,在墙上弹出外门窗水平、垂直控制线及伸缩缝、装饰线等,墙面涂料及面砖接缝线。; 挂基准线:在外墙各大角(阳角、阴角)及其它必要处挂垂直基准钢线,在每个楼层的适当位置挂水平线,以控制聚苯板的垂直和平整度。2.2粘贴翻包标准网格布; 翻包网格布粘贴位置在基层墙体上洞口周边及系统终端处,由于其直接关系到整个系统的封闭性,所以必须保证所有系统收头及设缝处无遗漏。; 将窄幅翻包标准网布的一端65压入墙面预抹的粘结胶浆内,胶浆厚度要求覆盖网格布,但能分辨网格布纹理为宜,余下甩出备
18、用。; 空调洞口或其他穿出洞口视洞口大小及形状裁剪细条网格布围贴,余下网布塞入洞口待板材粘贴完后勾出。; 立面如有面砖和涂料直接连接处(无结构分界)应设连接缝,预先铺设两道翻包布。2.3粘贴XPS板; 选用大小适中的干净、无杂质灰桶搅拌胶粘剂。拌和比例为5.5-6.25公升水+25公斤干粉,采用电动搅拌器充分搅拌均匀,静置510分钟后再稍加搅拌即可使用。; 每日工作结束时须将灰桶清洗干净、拭干备用。; 搅拌完成的伟伯胶粘剂可操作时间视气候条件不同约为23小时,超过时间的搅拌成品应弃用,为防止材料浪费和控制质量,应每天根据工作量由专人负责材料搅拌。; 外墙外保温用XPS板标准尺寸一般为600mm
19、1200mm,如非标准尺寸或局部不规则处可现场采用小型齿锯裁切,但必须注意切口与板面垂直,无碎粒。; 整块墙面应采用短边最小尺寸超过200mm的XPS板,且注意挑出墙角外板上不抹胶粘剂,墙角处板材应挑出一定长度以备弹线切割,在建筑物墙角只准许使用整块板或半块板。; 聚苯板拼缝不得正好留在门窗口的四角处,门窗洞口的聚苯板应用整块聚苯板裁出洞口。; 大面积排板时自墙面或分段底部沿水平顺序排列,上下错缝1/2板长,阴阳角处应做错茬处理,做法参见详图聚苯板排列示意图。将第一排保温板放置在支架(如木支架)或放在基层托架上,而后自下而上将板均匀粘贴到基层墙面上。每次都要检查保温板处基层的粘结情况。粘板时清
20、除板边溢出的胶粘剂,使板与板之间无“碰头灰”。大面积排板做法; 粘贴XPS板应用专用工具轻柔,均匀挤压XPS板,随时用2m靠尺和托线板检查平整度和垂直度。; 板缝要拼严,缝宽超过2mm时,用相应厚度的XPS板片填塞,板条不得粘结,更不得用胶粘剂直接填缝。拼缝高差不应大于1.5mm,否则应在XPS板至少粘贴24小时后用砂纸或打磨机打磨平整。打磨后应将板面清扫干净。; 用冲击钻在XPS板表面向内打孔,拧入或敲入锚固钉,钉头和圆盘不得超出墙面。; 锚栓的设置数量遵循国家标准及江苏省的地方标准,若标准中无相关说明,涂料饰面按20米以上部位每平方米4个设置,随所处的高度部位而已适当增加;20米以下部位可
21、以不设置锚栓。; XPS板粘结剂的粘结面积不小于40%。2.4抹面胶浆保护层(含网格布铺设); XPS板大面积铺贴结束后视气候条件48小时72小时后开始抹面胶浆保护层及网格布的铺设。; 操作前应先检查XPS板是否干燥,表面是否已平整并去除板面的有害物质、杂质和粉尘。; 大面积施工前,将预留甩出的翻包布用抹面胶浆固定在EPS板上,胶浆厚度要求覆盖网格布,但能分辨网格布纹理为宜。; 涂料饰面:用钢抹子在XPS板表面均匀涂抹一层抹面胶浆,厚度约为1.6mm。立即将网格布压入湿的胶浆中,待胶浆收水至可以碰触时,再立即涂抹第二道抹面胶浆,网格布约在两道抹面胶浆中间。贴网格布时,网格布的弯曲面应朝向墙面,
22、并从中央向四周用抹子抹平。抹面胶浆厚度(含网格布)2mm-4mm。; 如不采用腻子,为保证涂料饰面的光洁和平整度视保温系统抹面胶浆平整度或增抹一层抹面胶浆以保证涂料饰面效果。; 单张网格布长度不宜大于6m。铺贴遇有搭接时,标准网布应相互搭接至少65mm,要求全部抹面胶浆和网格布铺设完毕后,至少静置养护24h,方可进行下一道工序的施工。; 当遇到门窗洞口时应在洞口四角处沿45方向补贴一块标准网布,以防止开裂。; 门窗洞口上眉滴水采用滴水线构造,详见保温系统节点详图。2.5构造缝的设置; 基层墙体结构设有收缩缝、沉降缝和防震缝等,外墙外保温体系的施工不能破坏建筑物原有收缩缝、沉降缝和防震缝。进行苯
