Appl. No.:
11/859380
Inventors:
Kelvin L. Doerr - Omaha NE, US

Assignee:
Reward Wall Systems, Inc. - Omaha NE
International Classification:
E04B 1/38, E04C 5/00
US Classification:
52700, 52698, 52712, 52379, 52562
Abstract:
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. The attachment portion further includes an elongated slot for receiving the tie member, the tie member being adjustably movable along the length of the slot so as to be positionable between the courses of brick or other masonry material associated with the masonry wall structure as the masonry wall structure is being erected.

International Classification:
E04C002/54
US Classification:
052/506010, 052/782100, 052/633000
Abstract:
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. Another embodiment of the reinforcement member is utilized for reinforcing a modular concrete wall form with a ledge.
