GRC exterior wall decoration components have good molding ability and convenient processing, and can be made into various products with various shapes and special shapes according to the planning requirements, so they are widely used. So as a construction party, what are the main methods to fix GRC decoration components?

　　grc装修构件打孔，胀大螺栓装置孔洞：深度依据GRC构件分量确认运用胀大螺栓型号，依据胀大螺栓型号挑选适宜钻头，孔洞避开钢筋一次性成孔，孔洞的位置应依据GRC构件上预埋件位置确认。胀大螺栓装置，先将胀大管放进孔洞，用锤子适度敲击，装置螺母。

　　Drilling of GRC decoration components and holes of expanding bolt device: confirm the use of expanding bolt model according to the GRC component depth, select the appropriate drill according to the expanding bolt model, avoid the reinforcement to form holes at one time, and confirm the location of holes according to the location of embedded parts on GRC components. For the expansion bolt device, first put the expansion pipe into the hole, hit it moderately with a hammer, and install the nut.

　　胀大螺丝锚固法：将GRC板按装置要求在产品上预留螺孔——退拔状，螺孔距离水平向大于400mm，垂直方向不大于500mm，然后用胀大螺丝直接锚固在墙面上。

　　Expansion screw anchoring method: Reserve screw holes on the GRC Plate according to the requirements of the device - pull back shape. The distance between screw holes is more than 400mm in the horizontal direction and not more than 500mm in the vertical direction, and then directly anchor the GRC Plate on the wall with expansion screws.

　　　焊接法：在墙面上按GRC构件装置要求设置预埋铁件，然后用电焊焊。直接或用连杆把预埋在GRC内壁的钢板焊接。为了确保装置质量，在GRC构件装置之前，要对墙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15 mm，防止锈水外溢。

　　Welding method: set embedded iron parts on the wall according to the requirements of GRC component device, and then use electric welding. Weld the steel plate embedded in the inner wall of GRC directly or with connecting rod. In order to ensure the quality of the device, before the GRC component device, the attachments on the wall base surface shall be cleaned accordingly. The embedded parts are required to be within 15 mm of the outer wall surface to prevent the rust water from overflowing.
