Patent number: 9175486Abstract: ICF tooling facilitating the manufacturing of ICF blocks having different widths and different heights, the tie member including a variable width web portion positionable within a plurality of internal openings associated with a specially designed male tool, each internal opening being configured to receive folded web portions of varying length so that ICF blocks of different widths can be produced using the same male tool; each internal opening likewise includes a tie engaging feature for holding the respective tie members in their folded position within the male tool during the molding process; the internal openings enable foldable tie members of different widths to be used in the same male and female tools for producing ICF blocks in different widths in each individual separate male tool. ICF blocks of varying heights can be produced using the same female tool and a plurality of slightly modified height male tools.Type: GrantFiled: March 12, 2013Date of Patent: November 3, 2015Assignee: ICF MFORM LLCInventor: Henry E. Pfeiffer

Patent number: 9091089Abstract: A modular tie member which promotes flexibility in manufacturing ICF blocks of varying widths and heights, one embodiment including a pair of side wall bracket members each encapsulated within a respective panel member forming an ICF block and a web member pivotally attached to and extending between the side wall bracket members. Each bracket member may include an extension portion and/or another interlocking mechanism associated with each opposite end thereof positioned for overlapping and engaging similar members associated with similarly constructed tie members when one tie member is stackably arranged one on top of another tie member. The extension portions and/or the other interlocking mechanism extend into respective teeth associated with the horizontally opposed edges of the panel members for mating with the extension portions and/or the other interlocking mechanism of another tie member associated with a similarly constructed ICF block positioned in vertical arrangement thereto.Type: GrantFiled: March 12, 2013Date of Patent: July 28, 2015Assignee: ICF MFORM LLCInventor: Henry E.

Patent number: 8347581Abstract: An anchor assembly for use in joining together a masonry wall structure and a supporting back wall structure wherein the back wall structure is preferably formed using insulated concrete form (ICF) blocks each having a pair of opposed ICF panels associated therewith, the anchor assembly including an anchor member and a tie member. The anchor member includes an anchor portion adapted to penetrate one of the ICF panels and having at least one opening associated therewith so as to lie between the opposed ICF panels when attached thereto for allowing poured concrete to flow therethrough, and an attachment portion having a tab member positioned and located to overlay an ICF panel flange member when the anchor member is inserted within the ICF panel, the tab member being attachable to the ICF panel flange member.Type: GrantFiled: September 21, 2007Date of Patent: January 8, 2013Assignee: Reward Wall Systems, Inc.Inventors: Kelvin L. Doerr, Henry E. Pfeiffer

Patent number: 7730688Abstract: A corner bracket member for use in an Insulated Concrete Form (ICF) corner block or other form assembly having a pair of opposed inner and outer spaced apart panels for receiving concrete therebetween, the corner bracket member including at least a pair of side members, each side member having at least a pair of spaced apart flange members adapted for receiving and anchoring exterior facade or other surfaces thereto, and at least one concrete engaging member positioned and located so as to extend in a direction completely across the space formed by and between the inner and outer panels associated with the ICF corner block. The side members and flange members of the corner bracket member are encapsulated within one of the inner and outer panels and the at least one concrete engaging member includes a terminal end portion which is encapsulated within the other of the inner and outer panels when attached thereto.Type: GrantFiled: September 26, 2007Date of Patent: June 8, 2010Assignee: Reward Wall Systems, Inc.Inventor: Henry E.

Patent number: 7437858Abstract: A welded wire reinforcement is used in combination with insulated concrete form blocks having opposed panels joined by form ties. A method of construction forms building structures with insulated concert form blocks. The reinforcement member has a base bar and a plurality of arms extending downwardly from the base bar and is utilized to provide increased internal strength to a modular concrete wall system. The welded wire reinforcement provides vertical and horizontal support without requiring any extra time or material to connect a vertical reinforcement to the concrete forms of the wall system. An alternate embodiment of the reinforcement member includes a horizontal base bar, arms extending downward and perpendicular from the base bar, and a plurality of end pieces attached to the arms to form a discontinuous bottom bar. The base bar and bottom bar are slidably received in rebar chairs defined by the form ties.Type: GrantFiled: February 3, 2004Date of Patent: October 21, 2008Assignee: Reward Wall System, Inc.Inventors: Henry E. Pfeiffer, Kelvin Leslie Doerr, Karen Ann Bexten, Maher Khalil Tadros
