Abstract

748,693. Building panels. FLOWER, S. H., PARSONS, J., LOUDON N. G. W., and BELLROCK GYPSUM INDUSTRIES, Ltd. Feb. 4, 1953 [Feb. 4, 1952], No. 2907/52. Class 87(1). [Also in Group V] A building panel or slab comprises two facings a, e, Fig. 1, of plaster or like mouldable material (or one facing of plaster and one of concrete) the facings being connected by cellforming walls b. The walls are moulded (see Group V) in one with the facing a and are embedded in and 107 mechanically bonded to the facing e. The mechanical bonding is effected by ribs or (as shown) grooves d on the rims of the walls, these grooves being filled with the plaster of the facing e. The cell walls taper towards the facing e (see Fig. 15). The cell ends are concave at a1. Apertures f in the cell walls allow free air communication between the cells. The cells shown are mainly hexagonal, some of the side cells being half-hexagonal and the end cells being part: hexagonal: but all the cells may be half-hexagonal. The edges of the panel are grooved at c1 for the reception of plaster or cement grouting when the panels are placed edge to edge. The facings may be ribbed or grooved to key a facing of Portland cement &c. The plaster of the facing e may be different from that of the facing a and cell walls. Either or both lots of plaster may be plain, or reinforced with wires or wire netting or open mesh vegetable fabric. or mingled with vegetable or mineral fibres. Foamed plaster may be employed for the cell walls and either or both facings. The cells, when formed, may be filled with foamed plaster. The cells may be rectangular, triangular, polygonal, circular or oval. In a modification the facing e may be made of concrete, the rims of the cell walls adjacent this facing being dipped in a mastic or bitumen before this facing is applied thereto (this modified panel being for exterior use). In another modification the facing e may be of plaster or cement combined with a bitumen emulsion or other waterproofing composition so that it is impervious to water. Openings for windows and doors may be provided in the panel. Specification 748,749 is referred to.
