Welded wire reinforcement for modular concrete forms
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.
1. A one-piece reinforcement for reinforcing an insulated concrete ledge form having form ties, the form ties having at least one rebar chair, the one-piece reinforcement comprising:
a substantially rigid base including a plurality of rungs for extending into a ledge of the ledge form;
a plurality of arms connected to the respective rungs, said arms extending downwardly into the ledge;
at least one inner rail extending transversely of the arms so that said at least one inner rail joins said arms; and
an outer rail joining said rungs, said outer rail being positioned adjacent the terminal end of said rungs, said outer rail being at a different elevation as compared to said at least one inner rail, said at least one inner rail being positionable within the at least one rebar chair.
2. The reinforcement according to claim 1 wherein the rungs and arms are formed by continuous members bent to a ledge angle.
3. The reinforcement according to claim 2 wherein the ledge angle is approximately ninety degrees.
4. The reinforcement according to claim 1 wherein the outer rail is continuous.
5. An insulated concrete ledge form in combination with a one-piece reinforcement, the combination including:
the one-piece reinforcement comprising:
a substantially rigid base including an inner rail, an outer rail, and a plurality of rungs for extending into a ledge of the ledge form;
a plurality of arms extending downwardly into the ledge;
said outer rail being positioned adjacent the terminal end of said plurality of rungs;
said inner rail extending transversely across said plurality of arms and being positioned at an elevation which is lower than the elevation of said outer rail; and
the ledge form comprising:
a substantially straight concrete form wall;
a sloped concrete form wall defining a longitudinal slot for receiving the outer rail and defining a plurality of cavities for receiving the rungs; and
a plurality of cross ties joining the straight form wall and the sloped form wall, said cross ties each having at least one rebar chair, said inner rail associating with said at least one rebar chair.
6. The combination according to claim 5 wherein the cavities comprise substantially triangular slots open to a gap between the straight wall and the sloped wall.
