Abstract

Provided is a honeycomb panel for ceilings and walls, the honeycomb panel comprising a face sheet, a back sheet, and a honeycomb core. The back sheet is fastened to the face sheet, and a chamber is formed therebetween. The honeycomb core is arranged inside the chamber. Folded edges bending upward are symmetrically provided on two sides of the face sheet, and the folded edges have a double-layer structure. A keel limiting portion is provided on the inner side of the folded edge, and a limiting surface is provided on an upper end surface of the keel limiting portion. When the folded edge is inserted into a clamping groove of a keel, an upper end surface of the limiting surface abuts against the bottom of the keel. By arranging a keel limiting portion, a honeycomb panel can be fitted to a triangular keel in the entire length, and can maintain a flat surface. A thin aluminum sheet is bent to form a double-layer aluminum structure so as to increase the molding strength. The same effect and strength can be achieved on both sides by using an aluminum sheet which is half as thin as that on the market, thereby reducing aluminum sheet material costs by half.
