GRC外墻裝飾構件體薄、質量輕、高強度、高韌性、抗沖擊性能好、纖維分布均勻、防裂性好、制作簡便、造型豐富、用途廣泛。下面小編就為大家帶來了外墻GRC構件施工工藝方面的內容，希望能夠滿足大家的需求。
GRC exterior wall decorative components are thin, light, high strength, high toughness, good impact resistance, uniform fiber distribution, good crack resistance, easy to make, rich in shape, and widely used. The following small series brings you the content of the construction technology of GRC components of exterior wall, hoping to meet your needs.
施工要點
Key points of construction
設計要求及生產尺寸范圍須根據建筑物軸線尺寸、門窗洞位置、墻體轉角變化情況和墻體伸縮縫（沉降縫）的位置等因素來確定每個構件的長度，使構件的連接縫位置與建筑物立面統一協調對稱。且構件的大小適于制做與安裝。
The design requirements and production size range must determine the length of each component according to the axis size of the building, the position of the door and window holes, the change of the wall corner and the position of the wall expansion joint (settlement joint), so that the position of the connection joint of the component is unified, coordinated and symmetrical with the elevation of the building. And the size of the component is suitable for manufacturing and installation.
水平構件長度范圍可在1.2—2.4m之間。建筑物轉角處的水平構件須設計成陰陽角構件，不得使用構件切割拼接。陰陽角單邊長度可在0.3—1.2m之間。縱向構件單根長度一般可在1.2—3.6m之間。直徑大于800的柱子如運輸安裝具備條件，也可做成5—6m長，以避免或減少裂縫。檐線、腰線、窗臺線、門窗頂套類的水平方向使用的構件須設置滴水沿或滴水槽，以防止產生水痕污漬。
The length of horizontal members can range from 1.2 to 2.4m. The horizontal members at the corner of the building must be designed as internal and external corner members, and members shall not be cut and spliced. The length of one side of internal and external corners can be between 0.3-1.2m. The length of a single longitudinal member can generally be between 1.2-3.6m. If the transportation and installation of columns with a diameter greater than 800 are qualified, they can also be made into 5-6m long to avoid or reduce cracks. The components used in the horizontal direction of eave line, waist line, windowsill line and door and window top sleeve must be set with drip edges or drip tanks to prevent water stains.
安裝、固定方法
Installation and fixing methods
a、膨脹螺絲錨固法：將GRC板按安裝要求在產品上預留螺孔（退拔狀），螺孔間距水平向大于400mm，垂直方向不大于500mm，然后用膨脹螺絲直接錨固在墻（柱）面上。
a. Expansion screw anchoring method: Reserve screw holes (pullout shape) on the GRC Plate according to the installation requirements. The spacing of screw holes is greater than 400mm horizontally and not greater than 500mm vertically, and then directly anchor it on the wall (column) surface with expansion screws.
b、焊接法：在墻（柱）面上按GRC構件安裝要求設置預埋鐵件，然后用電焊焊。直接或用連桿把預埋在GRC內壁的鋼板焊接。
b. Welding method: set embedded iron parts on the wall (column) surface according to the installation requirements of GRC components, and then use electric welding. Weld the steel plate embedded in the inner wall of GRC directly or with connecting rod.
為了保證安裝質量，在
濟南GRC構件安裝之前，須對墻（柱）基體表面的附著物進行相應的清理。預埋件要求在外墻表面以內15mm，防止銹水外溢。
In order to ensure the installation quality, prior to the installation of GRC components in Jinan, the attachments on the surface of the wall (column) substrate must be cleaned accordingly. The embedded parts are required to be within 15mm of the outer wall surface to prevent rust water from overflowing.
