GRC構件在外墻上安裝時，一般是根據生產廠家提供的安裝圖，在外墻面上安裝8~10的普通膨脹螺栓，然后用中準6鋼筋將其與構件上預埋鋼筋焊接，或者是直接用膨脹螺栓將裝飾凸塊、窗頂花固定在墻面上。
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.
上述安裝辦法，在施工中一般都采用點焊的辦法，焊縫長度達不到要求，膨脹螺栓打入墻體后，很容易打在磚縫里，不能起到作用，達不到施工《規范》的要求，給GRC整體的安裝帶來了隱患。
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，當GRC產品連接安裝長度大30m時應設置伸縮縫，伸縮縫寬度不少于20mm，設置時應留在外墻面的陰角處或較隱蔽處，以免影響建筑物外形效果，伸縮縫以建筑油膏嵌縫。
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.
對于較長GRC附墻柱，在安裝時，可在多節間及柱底部采用30~3角鋼支架加固，并在接頭處用與GRC制品相同材料補縫封口，這種方法是有效防止GRC構件由于自重較重產生下滑而造成相鄰間產生裂縫的重要構造措施。
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.
當安裝附墻
濟南GRC構件的GRC柱及水平裝飾構件（無上蓋）時，其上口可采取兩種封口方式，一是在上口先鋪墊一層三合板，再鋪12×12mm鍍鋅鐵網，鐵網與墻面連接處應向上折起30~40mm，然后用1：2防水砂漿進行粉刷。
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.
并在出槍處做滴水線粉刷時由墻面向外放5%坡，防止頂面積水；另一種方式是先預制GRC蓋板安裝后，再進行外墻粉刷，但應處理好水泥蓋板接縫間的防水，好采用專用GRC蓋板。
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.
