Abstract
Abstract A construction panel comprises a non-combustible fire-resisting board e.g. of fibre-reinforced cement or calcium silicate binder, faced on one or both of its major faces with a metal facing. A "floating floor" for marine use is formed by joining the panels in edgewise abutting relationship. The joint is suitably formed by providing each panel with edge grooves placing the panels in edgewise abutting relationship, inserting a spline into the edge grooves of adjacent abutting panels and driving a staple into the abutting panels such that the limbs of the staple are deflected upon contacting the spline. The assembly of panels is suitably supported on a mass of mineral wool.
