1、 基层处理:墙面应清理干净无油渍、浮尘等,墙面大于4mm凸起物应剔除。使用喷涂法、刷涂法或辊涂法将界面砂浆均匀涂覆在需处理的基层墙体上。
1. Base course treatment: the wall shall be cleaned and free of oil stains, floating dust, etc., and the protrusions larger than 4mm on the wall shall be removed. The interface mortar shall be evenly coated on the base wall to be treated by spraying, brushing or roller coating.
2、弹基准线:根据施工图纸,在要安装线脚的部位弹出定位线(中线或边线)。
2. Snap the datum line: according to the construction drawings, snap the positioning line (center line or sideline) at the part where the line foot is to be installed.
3、配制砂浆:砂浆应按照规定配比用电动搅拌器搅拌均匀,一次配制用量以一小时内用完为宜。配制好的砂浆注意防晒避风,超过可操作时间不准继续使用。
3. Mortar preparation: the mortar shall be mixed evenly with an electric mixer according to the specified proportion, and the amount of one-time preparation shall be used up within one hour. The prepared mortar shall be protected from sun and wind, and shall not be used beyond the operable time.
4、线条安装:
4. Line installation:
1) 根据图纸安装尺寸切割EPS构件。EPS构件均为标准尺寸,切割时要考虑拼接缝宽。
1) Cut EPS components according to the installation dimensions of the drawing. EPS components are of standard size, and the splicing joint width shall be considered during cutting.
2) 使用专用粘结砂浆粘贴线条时,采用薄层满粘的方式,用力挤压线条确保线条满粘,无空鼓,注意线条周边溢出的粘接砂浆并保持线条表面清洁,粘结缝之间无碰头灰,灰缝随粘随勾,灰缝饱满。
2) When using special bonding mortar to paste lines, use a thin layer of full bonding method to squeeze the lines to ensure that the lines are fully bonded without hollowing. Pay attention to remove the bonding mortar overflowing around the lines and keep the line surface clean. There is no bump mortar between the bonding joints. The mortar joints are hooked as they are bonded, and the mortar joints are full.
3) 对于较大线脚,安装时要求设置支撑进行临时固定,在接口处为了防止开裂用无纺布进行处理。
3) For large wire feet, support shall be set for temporary fixation during installation, and non-woven fabric shall be used at the interface to prevent cracking.
4) 安装时若需拼接,应事先测量好拼装尺寸和角度,并在平整地方进行预拼装,缝隙大小应满足外观要求并符合规范标准。
4) If splicing is required during installation, the assembly size and angle shall be measured in advance, and pre assembly shall be carried out at a flat place. The gap size shall meet the appearance requirements and meet the specifications and standards.
5、 窗台、滴水槽等细部构造详图及防开裂措施应在技术标中明确。
5. The detailed structural details of windowsill, drip chute and other parts and anti cracking measures shall be specified in the technical bid.
6、 局部修整:
6. Local finishing:
1) 拼接完成后灰缝应用灰刀勾平,干燥后如有多余粘结砂浆可用砂纸或专用打磨工具打磨平整。
1) After splicing, the mortar joint shall be leveled with a mortar knife. If there is excess bonding mortar after drying, it can be polished with sandpaper or special grinding tools.
2) 拼接缝处理:拼接缝宽不大于2mm时,在安装完的次日进行拼接缝的砂纸打磨处理,使用抗裂剂或抹面砂浆粘贴100mm宽玻纤网格布,厚度小于2mm;拼接缝宽大于2mm时,缝内用薄聚苯片填塞后,再使用抗裂剂或抹面砂浆粘贴100mm宽玻纤网格布加强。干燥后,若线脚拼缝处留有多余砂浆处理方法同上。
2) Splicing joint treatment: when the width of the splicing joint is no more than 2mm, the splicing joint shall be polished with sandpaper on the next day after installation, and 100mm wide glass fiber mesh cloth with a thickness of less than 2mm shall be pasted with anti crack agent or plastering mortar; When the width of the splicing joint is greater than 2mm, the joint shall be filled with thin polystyrene sheet, and then pasted with 100mm wide glass fiber grid cloth with anti crack agent or plastering mortar for reinforcement. After drying, if there is excess mortar left at the seam of thread foot, the treatment method is the same as above.
7、 质量要求:
7. Quality requirements:
1) EPS线条需满足消防验收标准。
1) EPS line shall meet the fire acceptance standard.
2) 产品技术指标:吸水量:浸水24h≤500 g/㎡。抗风压值:不小于工程项目的风荷载设计值。耐冻融循环性(10次)::表面无裂纹、空鼓、起泡、剥离现象。 水蒸气湿流密度:≥0.85 g/(㎡?h)。 不透水性:试样防护层内侧无水渗透。 耐候性:表面无裂纹、粉化、剥落现象。。
2) Product technical index: water absorption: immersion for 24h ≤ 500g / ㎡. Wind pressure resistance value: not less than the design value of wind load of the project. Freeze thaw cycle resistance (10 times): no crack, hollowing, blistering and peeling on the surface. Water vapor wet flow density: ≥ 0.85 g / (㎡? H). Impermeability: there is no water penetration inside the protective layer of the sample. Weather resistance: no crack, pulverization and peeling on the surface..
