Patent number: 7761967Abstract: A method of assembling a metal shore post of a concrete forming assembly is disclosed. An outer telescoping tube is provided that has a main section with a first inside diameter and top portion with a section having a second inside diameter reduced relative to the first inside diameter of the outer tube. An inner telescoping tube is inserted for telescopic movement inside the outer tube. After assembly, a pair of pistons are inserted through access holes in the outer tube to provide a crushing force to the inner tube deforming it to create a region of increased diameter that is greater than that of the reduced diameter section but not so large as to prevent telescopic movement of the inner tube inside the outer tube. The increased dimension region thereby prevents accidental separation of the inner tube from the assembly, thereby improving safety and efficiency. Openings are provided in the inner tube in the region being crushed in order to control the region of deformation.Type: GrantFiled: May 11, 2006Date of Patent: July 27, 2010Assignee: Wilian Holding CompanyInventor: Robert McCracken

Patent number: 7210664Abstract: Supplemental bridging straps are used to increase the strength of a flexible metal concrete form assembly. A metal form has a flexible panel member with a perimetral flange projected laterally from one side thereof. Each of a pair of transversely opposite side sections of the flange is segmented by a plurality of longitudinally spaced V-shaped notches having their apices adjacent the one side of the panel member to provide for a lateral flexing movement of the panel member to a preselected shape. With the panel member in the predetermined shape, the segments in each of the flange side sections are connected together against relative movement to retain the predetermined shape of the panel member. In a first preferred embodiment, each flange segment is connected to an adjacent flange segment by a flexible metal strap. In a second preferred embodiment, extended flexible metal straps are used to interconnect a central flange segment to each of the pair of adjacent flange segments.Type: GrantFiled: August 6, 2004Date of Patent: May 1, 2007Assignee: Wilian Holding CompanyInventor: Robert McCracken

Patent number: 6502802Abstract: A corner form assembly for forming inside corners of concrete structures. A pair of double bias form components, each of which has an acute angle between a side rail and the face sheet are arranged with the side rails in contact engagement to form a form assembly with an inside angle equal to twice the acute angle of the side rails. A reverse bias coupler is used to join the double bias form components with conventional wall form panels having 90° end rails. The corner assembly acts to release the forces imposed on the components by the poured concrete upon disassembly and so allows the components to be readily stripped from the poured wall.Type: GrantFiled: February 23, 2001Date of Patent: January 7, 2003Assignee: Wilian Holding CompanyInventors: Larry Jorn, Robert McCracken
