Abstract

PURPOSE:To reduce weight and maintain strength by placing a reinforcing plate on the back of each stone panel, confronting their back faces to each other, interposing a honeycomb core in between, laminating, and installing a framing member peripherally at the side faces of the honeycomb core. CONSTITUTION:A reinforcing plate 4 such as FRP is adhered to the back face of each panel 1 of stone such as marble. Between the back faces of two such panels 1, a honeycomb core 2 and a framing 3 are adhered with a sheet-form epoxy adhesive, and a hot press is applied to achieve a laminate in a single piece. This enables securing rigidity and strength to the same degrees as conventional and reducing weight to a great extent.
