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、彈基準線：根據施工圖紙，在要安裝線腳的部位彈出定位線(中線或邊線)。

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、配制砂漿：砂漿應按照規定配比用電動攪拌器攪拌均勻，一次配制用量以一小時內用完為宜。配制好的砂漿注意防曬避風，超過可操作時間不準繼續使用。

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、線條安裝：

4. Line installation:

1) 根據圖紙安裝尺寸切割EPS構件。EPS構件均為標準尺寸，切割時要考慮拼接縫寬。

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) 使用專用粘結砂漿粘貼線條時，采用薄層滿粘的方式，用力擠壓線條確保線條滿粘，無空鼓，注意線條周邊溢出的粘接砂漿并保持線條表面清潔，粘結縫之間無碰頭灰，灰縫隨粘隨勾，灰縫飽滿。

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) 對于較大線腳，安裝時要求設置支撐進行臨時固定,在接口處為了防止開裂用無紡布進行處理。

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) 安裝時若需拼接，應事先測量好拼裝尺寸和角度，并在平整地方進行預拼裝，縫隙大小應滿足外觀要求并符合規范標準。

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、 窗臺、滴水槽等細部構造詳圖及防開裂措施應在技術標中明確。

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) 拼接完成后灰縫應用灰刀勾平，干燥后如有多余粘結砂漿可用砂紙或專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) 拼接縫處理：拼接縫寬不大于2mm時，在安裝完的次日進行拼接縫的砂紙打磨處理，使用抗裂劑或抹面砂漿粘貼100mm寬玻纖網格布，厚度小于2mm;拼接縫寬大于2mm時，縫內用薄聚苯片填塞后，再使用抗裂劑或抹面砂漿粘貼100mm寬玻纖網格布加強。干燥后，若線腳拼縫處留有多余砂漿處理方法同上。

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、 質量要求：

7. Quality requirements:

1) EPS線條需滿足消防驗收標準。

1) EPS line shall meet the fire acceptance standard.

2) 產品技術指標：吸水量：浸水24h≤500 g/㎡。抗風壓值：不小于工程項目的風荷載設計值。耐凍融循環性(10次)：：表面無裂紋、空鼓、起泡、剝離現象。 水蒸氣濕流密度：≥0.85 g/(㎡?h)。 不透水性：試樣防護層內側無水滲透。 耐候性：表面無裂紋、粉化、剝落現象。。

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..
