## Abstract

A concrete corner structure with diagonally oriented fiber resin polymer rebar and method that utilizes straight rebar to reinforce the corner structure. The straight rebar i intersects with the horizontally disposed rebar in the first and second walls that form the corner structure. The straight rebar is placed at a 45-degree angle with respect to the two walls and tied to the horizontally disposed rebar. This allows for the use of straight rebar to reinforce the corner structure as opposed to a curved rebar.

## Claims

### Claim 1

A method for pouring concrete walls using straight rebar reinforcements comprising:
placing an outside corner concrete form along a foundation to form a first and second wall that form a rectangular intersection;
placing a plurality of vertical reinforcement poles in the foundation a distance away from the outside corner concrete form;
attaching a plurality of straight, horizontally disposed, rebar to the vertical reinforcement poles;
attaching a fiber resin polymer (FRP) rebar that:
intersects with the horizontally disposed rebar in the first and second walls at a 45-degree angle to each,
has a length such that a first end of the FRP rebar extends outside the rectangular intersection and into the first wall, and a second end of the FRP rebar extends outside the rectangular intersection and into the second wall;
connecting the FRP rebar to the horizontally disposed rebar at each point in which they intersect;
placing a concrete cover at a distance away from the horizontally disposed rebar opposite the concrete form;
pouring concrete between the concrete form and concrete cover to form the first and second walls.

### Claim 2

A method for pooling concrete walls using straight rebar reinforcements comprising:
placing an outside corner concrete form along foundation to form first and second wall that form a rectangular intersection;
placing a plurality of vertical reinforcement poles in the foundation a distance away from the outside corner concrete form;
attaching a plurality of straight, horizontally disposed, rebar to the vertical reinforcement poles;
attaching a straight rebar that:
intersects with the horizontally disposed rebar in the first and second walls at a 45-degree angle to each,
has a length such that a first end of the straight rebar extends outside the rectangular intersection and into the first wall, and a second end of the straight rebar extends outside the rectangular intersection and into the second wall;
connecting the straight rebar to the horizontally disposed rebar at each point in which they intersect;
placing a concrete cover at a distance away from the horizontally disposed rebar opposite the concrete form;
pouring concrete between the concrete form and concrete cover to form the first and second walls.

### Claim 3 (depends on 2)

The method for pouring concrete walls of claim 2 wherein straight rebar is comprised of fiber resin polymer (FRP).

### Claim 4

First and second concrete poured walls forming a rectangular intersection, each wall having straight horizontally disposed rebar therein that extends from a backfill end of the intersection, through the intersection, and along the wall, and wherein the rebar in each respective first and second rail intersect each other, the improvement comprising,
a fiber resin polymer (FRP) rebar that:
intersects with the rebar in the first and second walls within the rectangular intersection at a 45-degree angle to each,
has a length such that a first end of the FRP rebar extends outside the rectangular intersection and into the first wall, and a second end of the FRP rebar extends outside the rectangular intersection and into the second wall.

### Claim 5

First and second concrete poured walls forming a rectangular intersection, each wall having straight horizontally disposed rebar therein that extends from a backfill end of the intersection, through the intersection, and along the wall, and wherein the rebar in each respective first and second wall intersect each other, the improvement comprising,
a rebar that:
intersects with the rebar in the first and second walls within the rectangular intersection at a 45-degree angle to each,
has a length such that a first end of the rebar extends outside the rectangular intersection and into the first wall, and a second end of the rebar extends outside the rectangular intersection and into the second wall.
