Abstract

This invention discloses an installation method for inverted GRC decorative panels, belonging to the field of architectural decoration construction technology. The steps include: installation of cantilever slab embedded parts and angle brackets; welding and installation of vertical keels and longitudinal main keels; prefabrication of GRC panels (with built-in reinforcing bars and reserved connection grooves); welding and anchoring of reinforcing bars on the inner and outer sides of the panels; and multi-layer sealing treatment of the joints. This invention adopts an angle steel keel + reinforcing bar welding + multi-point anchoring system, adapted to the stress characteristics of inverted installations, offering high safety, convenient construction, low cost, and good crack resistance and seepage prevention at the joints. It effectively solves the problems of unreliable installation, easy detachment, easy cracking, and inconvenient construction of existing inverted GRC panels, and is suitable for the construction of various irregularly shaped inverted GRC decorative panels.
