EPS构件腰线安装工艺流程:

材料准备→基层处理→现场定位、放线→安装EPS构件→安装锚固件→板面预留孔修补及接缝处理→组织验收

一、基层处理:要求同CB板之间EPS构件基层。

二、 现场定位、放线:EPS构件的上部定位根据挑檐的位置确定,然后分别弹出中线和下边线来确定EPS构件的位置。

三、安装EPS构件:

1)EPS构件粘贴时,应使用专用粘结复合型砂浆,粘结面积100%,用力挤压EPS构件使砂浆从周边溢出,粘接缝宽不大于3mm,粘接缝应随粘随勾,灰缝饱满,并保持EPS构件表面的整洁。

2)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,缝隙不大于3mm。用专用粘结复合型砂浆作拼接粘结材料,砂浆稠度可稍大些,采用满粘法进行。拼接时要求稍微、均匀用力挤压,以使灰缝满足。

3)拼接完灰缝应用灰刀勾平,使EPS构件成为一体。干燥后,若EPS构件拼缝处留有多余粘结砂浆可用砂纸进行打磨。

四、安装锚固件:

1)锚固件安装应至少在粘完板的24h后再进行;

2)用电钻在EPS构件表面向内打孔,进墙深度不小于50mm,用锤子轻敲,使其略低于板面。

3)锚固件的布置点数及位置根据EPS构件规格尺寸确定,但每平米不少于5个,特别注意任何面积小于0.02㎡的单板必须加锚固件固定。

五、板面预留孔修补及接缝处理:预留安装空用抗裂砂浆修补平整,EPS构件板接缝处上下搭接100mm的网格布抹抗裂砂浆增强处理。

EPS component waist line installation process flow:

Material preparation → base treatment → site positioning and setting out → installation of EPS components → installation of anchors → repair of reserved holes and joint treatment on board surface → organization of acceptance

2.1 base course treatment: it is required to be the same as the base course of EPS component between CB board.

2. According to the location of the center line of EPS, the location of the upper part and the center line of EPS are determined.

2.3 installation of EPS components:

1) When pasting EPS components, special bonding composite mortar should be used, with bonding area of 100%. Squeeze EPS components to make mortar overflow from the periphery. The width of bonding joint should not be more than 3mm. The bonding joint should be hooked along with bonding, the mortar joint should be full, and the surface of EPS components should be kept clean.

2) During installation, if splicing is required, the assembly size and angle shall be measured in advance, and the pre assembly shall be carried out at a flat place, and the gap shall not be greater than 3mm. When the special bonding composite mortar is used as the splicing bonding material, the mortar consistency can be slightly larger, and the full bonding method is adopted. When splicing, it is required to squeeze slightly and evenly to make the mortar joint meet the requirements.

3) After splicing, the mortar joint shall be leveled with a gray knife to make EPS components integrated. After drying, if there is surplus bonding mortar left at the joint of EPS components, sandpaper can be used for grinding.

2.4 installation of anchors:

1) Anchor installation should be carried out at least 24 hours after the board is glued;

2) Use an electric drill to drill holes inwards on the surface of EPS components, the depth into the wall shall not be less than 50 mm, and tap gently with a hammer to make it slightly lower than the board surface.

3) The number and location of anchors shall be determined according to the specification and size of EPS components, but no less than 5 anchors per square meter. Special attention shall be paid to any single board with an area less than 0.02 square meter, which must be fixed with anchors.

2.5 repair of reserved holes on board surface and joint treatment: the reserved installation space shall be repaired and leveled with anti crack mortar, and the joint of EPS component board shall be overlapped with 100 mm mesh cloth and strengthened with anti crack mortar.
