Expansible construction form and method of forming structures
Abstract
Abstract A FORM IS DISCLOSED INCLUDING COLLAPSIBLE-EXTENSIBLE SIDE MEMBERS WITH RIGID, TRANSVERSE CONNECTING ELEMENTS DISPOSED BETWEEN THE SIDE MEMBERS PROVIDING, IN THE EXTENDED POSITION, A SELF-SUSTANINING STRUCTURE ATTACHABLE TO PILASTERS MOUNTED IN NON-FERROUS SUPPORT STRUCTURES DRIVEN INTO THE GROUND. THE TRANSVERSE CONNECTING ELEMENTS MAY BE COUPLED TO THE SIDE MEMBERS BY NON-CORRODIBLE FASTENERS TO PREVENT CORROSION OF THE TRANSVERSE ELEMENTS WHICH WILL TYPICALLY BE MADE OF STEEL. THE TRANSVERSE ELEMENTS ALSO FUNCTION AS REINFORCING IN THE FINAL, POURED STRUCTURE. A METHOD OF FORMING A WALL STRUCTURE IS ALSO DISCLOSED IN WHICH SPACED SUPPORTS ARE DRIVEN INTO THE GROUND, UPRIGHT PILASTERS ARE ATTACHED TO THE SUPPORTS, AND COLLAPSIBLE-EXTENSIBLE SIDE MEMBERS, DISPOSED IN PREDETERMINED, SPACED RELATION WITH EACH OTHER BY MEANS OF A COLLAPSILBE-EXTENSIBLE FRAME MEANS, ARE EXTENDED TO SPAN THE DISTANCE BETWEEN THE PILASTERS AND THE FRAME MEANS IS ATTACHED THERETO. CEMENTITIOUS MATERIAL IS THEN POURED BETWEEN THE SIDE MEMBERS AND ALLOWED TO SET, AT LEAST THE FRAME MEANS PROVIDING REINFORCING WITHIN THE CEMENTITIOUS MATERIAL.
