Abstract: Among other things, a load bearing wall structure for a building is disclosed. The load bearing wall structure includes frameless modular wall panels with each frameless wall panel having spaced skins of fiber reinforced cement sheet separated by a core of expanded in situ high density polyurethane foam bonded to inner faces of the spaced skins. Each frameless wall panel also has formed in upright edges a recessed channel forming, together with a recessed channel of an edge-abutting wall panel, a hollow aperture extending between top and bottom surfaces of the abutting frameless wall panels. A lower panel edge locating channel member securable to a building support base is also included. Further included is an upper panel edge locating channel member and a tensionable element extending via each hollow aperture between an anchor member secured to the base and the upper panel edge locating channel member.

Abstract: A system for manufacturing foamed plastics laminated panels at a high volume is disclosed. Press modules include a pair of opposed spaced open frame members with longitudinal raised sections attached to perpendicular supports. The open frame members move relative to one another, support respective panel outer skin layers; and recieve therebetween edge sealing members of a predetermined thickness. A spacing between the open frame members and a hinge is adjustable to move a first open frame member relative to a second frame member. Clamps retain the open frame members in a predetermined space relationship, and when actuated, forms a mould cavity defined by the outer skin layers and edge sealing members supported by the open frame members. An inlet introduces an a liquid foamable plastics material into the moulded cavity, and a delivery system delivers liquid reactants in predetermined proportions to a selected mould cavity formed in a selected press module.

Abstract: An apparatus for manufacture of foamed plastics laminated panels having; an array of press modules, each comprising of opposed spaced frame members movable relative to one another; adjustment means to adjust spacing between said frame members; hinge to allow a first frame member to move relative to a second frame member; clamp to retain, in use, said frame members in a predetermined spaced relationship, two outer skin layers, in use, are spaced and located on the opposing inner surfaces of the respective frame members; sealing members locatable, in use, between said frame members and two outer skin layers, to define a mould cavity between said opposed outer skin layers when said clamp is actuated, at least one inlet to introduce into said mould cavity a liquid foamable plastics material: respective reservoirs of liquid reactants, for producing a foamable plastic; and delivery means to deliver liquid reactants in predetermined proportions to respective mould cavities.

Abstract: A building structure comprising one or more modular panels (5); a wall locating member (12) positioned between a base (2) and the one or more modular panels (5); a top member (19) placed on top of the modular panels (5); and a plurality of tie rods (14). The modular panels (5) when adjoining to form a wall create longitudinal cavities (16) within the wall. The plurality of tie rods (14) extend through said longitudinal cavities (16) and secure said top member (19), walls (3) and wall locating member (12) to the base (2).
