GRC构件在外墙上安装时，一般是根据生产厂家提供的安装图，在外墙面上安装8~10的普通膨胀螺栓，然后用中准6钢筋将其与构件上预埋钢筋焊接，或者是直接用膨胀螺栓将装饰凸块、窗顶花固定在墙面上。
When GRC components are installed on the external wall, 8~10 ordinary expansion bolts are generally installed on the external wall according to the installation drawing provided by the manufacturer, and then the standard 6 reinforcement is used to weld it with the embedded reinforcement on the component, or the decorative boss and window top flowers are directly fixed on the wall with expansion bolts.
上述安装办法，在施工中一般都采用点焊的办法，焊缝长度达不到要求，膨胀螺栓打入墙体后，很容易打在砖缝里，不能起到作用，达不到施工《规范》的要求，给GRC整体的安装带来了隐患。
As for the above installation methods, spot welding is generally adopted in the construction, and the weld length can not meet the requirements. After the expansion bolt is driven into the wall, it is easy to hit the brick joint, which can not play a role, and can not meet the requirements of the construction specification, which brings hidden dangers to the overall installation of GRC.
因此，当GRC产品连接安装长度大30m时应设置伸缩缝，伸缩缝宽度不少于20mm，设置时应留在外墙面的阴角处或较隐蔽处，以免影响建筑物外形效果，伸缩缝以建筑油膏嵌缝。
Therefore, when the GRC product connection installation length is greater than 30m, the expansion joint should be set, and the width of the expansion joint should not be less than 20mm. When setting, it should be left in the inner corner of the outer wall or in a more hidden place, so as not to affect the shape effect of the building. The expansion joint should be caulked with building ointment.
对于较长GRC附墙柱，在安装时，可在多节间及柱底部采用30~3角钢支架加固，并在接头处用与GRC制品相同材料补缝封口，这种方法是有效防止GRC构件由于自重较重产生下滑而造成相邻间产生裂缝的重要构造措施。
For long GRC wall attached columns, during installation, 30~3 angle steel supports can be used at multiple sections and column bottom for reinforcement, and the joints shall be filled and sealed with the same materials as GRC products. This method is an important structural measure to effectively prevent GRC members from sliding due to heavy self weight and causing cracks between adjacent members.
当安装附墙
济南GRC构件的GRC柱及水平装饰构件（无上盖）时，其上口可采取两种封口方式，一是在上口先铺垫一层三合板，再铺12×12mm镀锌铁网，铁网与墙面连接处应向上折起30~40mm，然后用1：2防水砂浆进行粉刷。
When installing GRC columns and horizontal decorative components (without upper cover) of Jinan GRC components attached to the wall, the upper opening can be sealed in two ways: one is to lay a layer of plywood on the upper opening first, and then 12 × 12mm galvanized iron mesh, the connection between the iron mesh and the wall shall be folded up by 30~40mm, and then painted with 1:2 waterproof mortar.
并在出枪处做滴水线粉刷时由墙面向外放5%坡，防止顶面积水；另一种方式是先预制GRC盖板安装后，再进行外墙粉刷，但应处理好水泥盖板接缝间的防水，好采用专用GRC盖板。
A 5% slope shall be set outward from the wall to prevent water in the top area when painting the drip line at the gun outlet; The other way is to prefabricate GRC cover plate and install it before painting the external wall. However, the waterproof between the joints of cement cover plate shall be properly handled and special GRC cover plate shall be used.
