Building panels and building system using such panels

摘要

A wall panel system has at least one panel 10 with first 12 and second 14 opposed external panel face sheets of compressed solid cement or gypsum based material bonded to a foam core 16. The core has at least one channel 22, 24 extending through the core on an axis along the length of the panel from a predetermined position on a top edge 30 to a bottom edge 32 of the panel determined by the width and thickness of the panel. A slot 18, 20 is provided on opposed side/end edges of the core to allow for a strengthening rod to be inserted between adjacent panels. An edge recess 26 extends along one or more edges of the panel between the rear of the face sheet(s) and the core. The core can be machined e.g. routed to create the recess 26. The recess can receive and discretely hide connecting panel/plate members connecting adjacent panels. Each core can include channels inset from the edges to accommodate utilities, such as electrical wiring and plumbing pipe.
