Welding method: embedded iron parts shall be set on the wall (column) surface according to the requirements of GRC component device. Before installing GRC components, the attachments on the base surface of the wall (column) must be cleaned accordingly. The embedded parts shall be within 15mm of the outer wall surface to prevent rust water from overflowing.
Expansion screw anchoring method: Reserve screw holes (pull-out shape) on GRC components according to the installation requirements. The spacing of screw holes shall be greater than 400mm in the horizontal direction and greater than 500mm in the vertical direction, and then directly anchor and fix them on the wall (column) surface with expansion screws, and then use electric welding. Methods: the steel plate embedded in the inner wall of GRC was welded directly or with connecting rod to ensure the quality of the device.
The real GRC component should be the precursor alkali resistant fiber short cut, sprayed into the mold together with the mortar equipped with additives, and then rolled and formed layer by layer. In particular, the main index of unqualified GrC is whether the fiber content is about 5%, and there is no fiber content of grc1% of grid cloth.
