The other end of the base has a vertically arranged square steel, and the square steel is detachably connected to the base via bolts. The outer side of the square steel is connected to the horizontally arranged square tube steel, one side of the square tube steel is welded to the outer side of the square steel, and the other side of the square tube steel is connected to the external panel via a plurality of the concealed frame keels.

9. The curtain wall external corner mounting structure according to claim 8, characterized in that: The base comprises a web and a wing plate, the web is perpendicular to the wing plate, and the wing plate is attached to the second steel plate; The outer end of the web is provided with first holes on both sides, the square steel is located inside the outer end of the web, and the square steel is provided with second holes on both sides, the first hole is matched with the second hole, and the square steel is connected to the outer end of the web by bolts passing through the first hole and the second hole; The horizontally arranged square tube steels are evenly distributed along the vertical direction, and the vertically arranged square steels are evenly distributed along the horizontal direction.

10. A curtain wall external corner installation method, characterized in that: The steps include: Step 1: Lay out horizontal and vertical control lines on the wall, and then lay out the panel arrangement lines of the external panels according to the curtain wall layout design, combined with the position, elevation and characteristics of the curtain wall facade changes. According to the on-site conditions after the layout, measure the actual construction of the civil structure, and deal with the positions with large errors that need to be adjusted; Step 2: Install the first steel plate according to the positioning and design spacing of the square steel. The first steel plate is fixed to the wall through expansion bolts. After the installation is completed, use a torque wrench to check the tightening strength of the bolts and nuts, and fix them by spot welding. Determine the position of the clip assembly according to the vertical control line. During construction, first spot weld the clip assembly on the first steel plate, then check its three-dimensional errors one by one, and fully weld and fix it after the inspection and adjustment are qualified; After the first installed steel plate and clip assembly are inspected and accepted, the welding position is treated with anti-corrosion; Step 3: Install the insulation layer on the cleaned wall. The installation of the insulation board should be determined according to different projects and their specific requirements, but must comply with the "Construction Quality Acceptance Code for Energy-Saving Building Projects" GB50411-2007; Step 4: Install the triangular keel. Install the triangular keel to the connecting section at the outer end of the clip assembly by means of bolts. After installation, use a torque wrench to check the tightening strength of the bolts and nuts. Adjust and fix the position of the triangular keel according to the horizontal and vertical reference lines and the wall end lines; Step 5: Connect the horizontally set square tube steel to the triangular keel, adjust its position according to the distance between the external panel and the wall, and fully weld it after inspection and adjustment, and perform anti-corrosion treatment on the welding position; Step 6: Cut the external panels, and cut the external panels at the positive corners of the curtain wall at 45°. Step 7: Slide the outer end of the concealed frame keel into the mounting groove provided on the inner surface of the external hanging board, and install four concealed frame keels on the inner surface of each external hanging board; Hang the external panels on the square tube steel through the concealed keel, and install them layer by layer from bottom to top. After the initial installation of the external panels, adjust the panels to ensure that the external panels are horizontal and vertical, and the gap size meets the requirements by adjusting the flatness and verticality of the external panels; Step 8. After the construction is completed, clean it directly with clean water. Locally contaminated areas can be cleaned with cotton cloth dipped in xylene solvent. When mortar is splashed on the external board, clean it with a short-bristled brush when it is almost dry, and then rinse with clean water. Do not polish directly with sandpaper to avoid damaging the self-cleaning layer of the external board.
