The specific steps for dry-hanging stone arcs are:

Installation steps: 1. Determine the installation position of the pendant according to the layout diagram, and use stainless steel screws to combine pendant GJ-1 with pendant GJ-3 The serrated structure is fixedly connected to the auxiliary keel by removing the stitches on the inside. 2. On the outer facade of the installed pendant GJ-1, use stainless steel screws to firmly connect the pendant GJ-4 and the zigzag structure of the pendant GJ-3 to the pendant GJ-1. 3. Check the flatness and firmness of the installed combined pendant, start installing the stone panel, and insert the two parallel sides of the single stone panel into the dry hanging slot and fix it with the pendant GJ-4. 4. After adjusting the curvature and slope of the installed stone panel, insert the pendant GJ-5 into the U-shaped groove at the lower end of the pendant GJ-4. 5. Install the adjacent stone panels and snap the pendant GJ-5 into the two parallel sides to form a sub-frame system. 6. After adjusting the above installed combination pendants and stone panels, install the pendant GJ-2. Install the pendant GJ-2 in the U-shaped groove formed by the installation of the pendant GJ-5. The principle of mortise and tenon structure and flexible connection make it easy to install and adjust, and to replace and repair damaged stone panels. 7. The stone arrangement of the hyperboloid wall is special. The pendant GJ-6 is a fixed system compared to the above combined pendant (adjustable system) and is suitable for the vertical joint between two stones. The combination pendant is suitable for the joint between the upper and lower stones and is easy to adjust. The pendant GJ-6 is used in conjunction with the combined pendant to facilitate two-way adjustment, ensuring safe and reliable dry hanging of stone and good earthquake resistance. 8. Unit sample production and installation: process the stone panels in the same part and conduct on-site trial hanging to form a unit sample. 9. Stone panel installation: For dry hanging, the center point of the two arcs is used as the central axis. From the center point to both sides, the order is from bottom to top, and the combined pendants can be clicked in order to install. 10. Stone surface cleaning: After the stone panel is installed, clean the surface contamination and dust in the gaps in a timely manner. 11. Inject sealant. 1) Paste anti-fouling strips along the edges of the panels, and the edges should be aligned and tight. Embed elastic foam rods in the gaps between panels. The diameter of the foam rods should be slightly larger than the width of the glue seam. 2) When injecting glue, apply even force, move the gun steadily and slowly, and use special tools to make the glue seam form a concave arc. 3). Glue injection is not allowed on windy and rainy days. If the glue contaminates the board surface, it should be wiped immediately and cleaned with detergent. 4) After the glue injection is completed, check the quality of the glue joint and clean the surface of the stone slab after passing the test.

Dry-hanging (English name: dry-hang) refers to the abbreviation of a hanging construction method that uses metal hangings to firmly hang decorative materials on the structure to form a facing.
