Abstract: A connection element formed of a strip of a corrugated sheet and including a plurality of bearing surfaces (3) spaced from each other and located in a common plane; at least one attachment opening (6, 7) formed in at least one bearing surface (3); a plurality of free-lying top surfaces (4) extending parallel to the bearing surfaces (3); free-lying legs (5) extending between respective bearing surfaces (3) and the top surfaces (4); and at least one through-opening (10, 11, 12, 13, 14, 15, 16, 17) formed in at least one of free-lying top surfaces and legs.

Abstract: A reinforced panel structure made by impregnating resin in a knitted fabric and allowing the resin to cure. The fabric comprises first and second spaced layers (1,2) which are interlinked by an intermediate pile layer (3) comprising two sets of ribs (4,5). The ribs (4) comprise monofilament yarns having a relatively high stiffness sufficient to provide a restoring force during impregnation of the fabric with resin. The ribs (5) are made from multifilament yarns, spun yarns or composite yarns, selected for desired properties of the finished fabric and/or for their wetting properties during impregnation.

Abstract: A structural panel system that has two skin members that are separated by a plurality of semi-flexible support members disposed therebetween. The support members and the skin members are adhered together by a semi-flexible core member. The outer skin member is movable relative to the inner skin member. The first skin member may be perforated and encapsulated by either the core member or a cementitious material to provide a variety of panel surfaces.

Abstract: An interlocking corrugated fluted panel for use in constructing a foundation wall for a building where a plurality of the panels are attached to a presupported building member and the panels hang downwardly into a foundation support opening. At the bottom portion of each fluted panel, the flutes extending outwardly from the building are cut along a bend line and the bottom portion of the panel is bent inwardly approximately 90°, the bent portion forming an anchorage when concrete is placed around the bottom of the panels. At the lower edge of each panel a cut flute is bent into either an interlocking male or female shape.
