Abstract (en)
[origin: WO9626055A1] A method of moulding a unitary hollow building panel (10) having opposed outer spaced apart walls (11, 12) interconnected by a plurality of webs (13) which together with the walls (11, 12) form cavities (14) extending between opposite sides of the panel, wherein a plurality of removable plug members (20) are inserted so as to lie transversely of a tray-like mould (15) and supported with their underside surfaces spaced from the base wall of the mould (15) the spaces between adjacent plug members (20) defining internal mould cavities for the formation of the panel webs (13), and wherein quantities of a wet pourable mix of a mouldable material together with reinforcement material are added to the tray-like mould to embed the plug members (20) and to fill the spaces therebetween, and wherein after the wet pourable mix in the mould has set, the internal plug members (20) are withdrawn by an extraction unit (21), horizontally sideways from the mould, whereafter the moulded panel (10) is removed from the mould (15).
