GRC外墙装饰构件体薄、质量轻、高强度、高韧性、抗冲击性能好、纤维分布均匀、防裂性好、制作简便、造型丰富、用途广泛。下面小编就为大家带来了外墙GRC构件施工工艺方面的内容，希望能够满足大家的需求。
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.
施工要点
Key points of construction
设计要求及生产尺寸范围须根据建筑物轴线尺寸、门窗洞位置、墙体转角变化情况和墙体伸缩缝（沉降缝）的位置等因素来确定每个构件的长度，使构件的连接缝位置与建筑物立面统一协调对称。且构件的大小适于制做与安装。
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.
水平构件长度范围可在1.2—2.4m之间。建筑物转角处的水平构件须设计成阴阳角构件，不得使用构件切割拼接。阴阳角单边长度可在0.3—1.2m之间。纵向构件单根长度一般可在1.2—3.6m之间。直径大于800的柱子如运输安装具备条件，也可做成5—6m长，以避免或减少裂缝。檐线、腰线、窗台线、门窗顶套类的水平方向使用的构件须设置滴水沿或滴水槽，以防止产生水痕污渍。
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.
安装、固定方法
Installation and fixing methods
a、膨胀螺丝锚固法：将GRC板按安装要求在产品上预留螺孔（退拔状），螺孔间距水平向大于400mm，垂直方向不大于500mm，然后用膨胀螺丝直接锚固在墙（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：在墙（柱）面上按GRC构件安装要求设置预埋铁件，然后用电焊焊。直接或用连杆把预埋在GRC内壁的钢板焊接。
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.
为了保证安装质量，在
济南GRC构件安装之前，须对墙（柱）基体表面的附着物进行相应的清理。预埋件要求在外墙表面以内15mm，防止锈水外溢。
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.
