GRC构件如何安装,技巧有哪些?
How to install GRC components and what are the skills?
根据施工图纸,在待安装grc构件的部位弹出定位线(中线或边线)。grc构件粘贴时,网格布应当翻包,如有特殊情况可直接粘贴不翻包。采用薄层满粘法进行粘贴,用力挤压EPS构件使砂浆从周边溢出,粘接缝宽不大于3mm。粘结缝应随粘随勾,灰缝饱满,并保持EPS构件表面的整洁。对于较大grc构件,安装时要求设置支撑进行临时固定。
According to the construction drawings, snap the positioning line (center line or side line) at the position of GRC components to be installed. When pasting GRC components, the grid cloth shall be turned over. In case of special circumstances, it can be directly pasted without turning over the package. The thin-layer full bonding method shall be adopted for bonding, and the EPS components shall be squeezed to make the mortar overflow from the periphery, and the bonding joint width shall not be greater than 3mm. The bonding joint shall be hooked at the same time, the mortar joint shall be full, and the surface of EPS components shall be kept clean. For large GRC members, supports are required for temporary fixation during installation.
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。粘结砂浆作拼接粘结材料,砂浆稠度可销大些,采用薄层满粘法进行。拼接时要求稍微、均匀用力挤压锤打,以使灰缝满足要求。拼接完灰缝应用灰刀勾平,使grc构件成为一体。干燥后,若grc构件拼缝处留有多余粘结砂浆可用砂纸进行打磨。
During installation, if splicing is required, the assembly size and angle shall be measured in advance, and pre assembly shall be carried out at a flat place with a gap of no more than 3mm. The bonding mortar is used as the splicing bonding material. The mortar consistency can be larger, and the thin-layer full bonding method is adopted. During splicing, it is required to squeeze and hammer slightly and evenly to make the mortar joint meet the requirements. After splicing, the mortar joint shall be leveled with a mortar knife to integrate the GRC components. After drying, if there is excess bonding mortar left at the joint of GRC components, it can be polished with sandpaper.
干燥后,grc构件拼接部位抗裂专用胶进行处理。处理方法见抗裂专用胶使用说明。施工完的grc构件就注意成品保护,严禁蹬踏、重物撞击。如有损坏,应将整块EPS构件剔除重装。
After drying, the GRC component splicing part shall be treated with special anti crack adhesive. For the treatment method, see the instructions for the special anti crack adhesive. Pay attention to the protection of finished GRC components after construction, and it is strictly prohibited to step on or hit by heavy objects. In case of damage, the whole EPS component shall be removed and reinstalled
