Abstract

A compound construction panel for double floors used in room air conditioning, comprising an external, tub-shaped sheath formed of a high tensile-strength and high Young's modulus material, a filler in the sheath formed of a low tensile strength and low Young's modulus material, and a rigid annular body disposed in an aperture in the bottom of the sheath and extending to the upper portion of the sheath. The annular body is anchored in the filler and is provided with a radially inwardly projecting annular flange at its lower portion which serves as a support for an air discharge nozzle, a dirt-catcher or the like.
