[0002] The external corner is a term in the construction industry, which refers to the protruding corners of a wall surface, such as the protruding corners of a building and the included angle between a door and window opening and a wall surface. Correspondingly, the internal corner refers to the recessed corners of a wall surface.

[0003] In order to improve the aesthetics of the indoor external corner, when the arc-shaped facade panel is installed at the external corner, an appropriate support needs to be welded, and then the arc-shaped facade panel is installed on the support by means of gluing, so as to realize the installation of the facade panel. The construction cost is high, the gluing method needs to wait for the glue to solidify before the next step of construction and installation, which is time-consuming, and a large amount of glue is used, which is not conducive to green and environmentally-friendly construction. In addition, the arc-shaped facade panel is mostly constructed by on-site bending, which is prone to elastic deformation. After being bonded to the support, more supports need to be installed to prevent the arc-shaped facade panel from falling off the support due to deformation. Therefore, the application provides a facade panel external corner mounting node and a construction method, which uses a clamping type installation method to install the arc-shaped facade panel, improves the construction efficiency, and does not need to use glue, which is environmentally-friendly.

Fix the angle iron (52) to the L-shaped connecting seat (3) by tapping. Fix the lock seat (51) to the wall decorative panel (1) by tapping. Measure the angle iron (52) according to the position of the insertion hole (55) on the lock seat (51) and... Make a mark, weld the square positioning block (591) to the marked position, take the electric drill and drill a hole in the angle iron (52) through the inner cavity of the square positioning block (591), take the pin (53) so that the square positioning groove (592) fits on the surface of the square positioning block (591), then take the cross screw (593) through the angle iron (52) and the square positioning block (591) and screw it into the inner cavity of the threaded hole (594) so ​​that the pin (53) is fixed on the angle iron (52), then take the wall panel (1) so that the T-shaped hanging strip (66) on the mounting plate (65) hangs on the inner cavity of the hanging groove (64) on the hanging square steel (63) to realize the hanging installation of the wall panel (1). The rubber strip (68) on the hanging square steel (63) abuts against the mounting plate (65) to effectively prevent the wall panel (1) from shaking after installation. Step 2: Pick up the elastic support component (7) so that angle iron 2 (71) is installed at the indoor corner through the pre-embedded plastic expansion bolts. Then pick up the curved corner trim panel (2) and bend it inward so that the curved corner trim panel (2) deforms, making it easier for the curved corner trim panel (2) to enter between the two wall trim panels (1). Insert the pin (53) fixed on angle iron 1 (52) into the inner cavity of the insertion hole (55) on the lock seat (51). When the curved end of the pin (53) contacts the lock rod (57), it will drive the lock rod (57) to slide into the inner cavity of the cavity (56) and squeeze the spring 1 (58) until the lock rod (57) is aligned with the lock groove (54). The rebound force of 8) causes the locking rod (57) to enter the inner cavity of the locking groove (54), realizing the fixed installation between the two ends of the arc-shaped corner decorative panel (2) and the wall decorative panel (1). At this time, the inner side of the arc-shaped corner decorative panel (2) abuts against the two pulleys (73). The pulleys (73) cause the two swing arms (72) to rotate in opposite directions. The pulleys (73) then pull the connecting plate (76) and the sliding plate (75) to move and stretch the second spring (78). The rebound force of the second spring (78) causes the pulley (73) of the swing arm (72) to abut against the inner side of the arc-shaped corner decorative panel (2), providing elastic support to the inner side of the arc-shaped corner decorative panel (2) and improving the deformation resistance of the arc-shaped corner decorative panel (2).
