Abstract

A rebar set-up bar used to construct a rebar grid that provides reinforcement for a concrete wall or structure. The set-up bar is vertically positioned in the grid and includes a metal or steel rod having a plurality of supports. The supports are attached to the elongated rod at intervals and are adapted to receive horizontal rebars therein.

Claims

1. A set-up bar for use in a rebar grid, the set-up bar comprising:

an elongated rod having an upper end and a lower end;

a plurality of supports attached to the elongated rod at intervals, each support formed from a rebar or a steel rod and including a lower portion, an upper straight portion and an intermediate curved portion, the lower portion in combination with the curved intermediate portion forming a channel with an opening that faces the upper end of the elongated rod, the channel adapted to receive a rebar therein, and the upper straight portion is attached to the rod.

2. The set-up bar according to claim 1, wherein the elongated rod is a rebar.

3. The set-up bar according to claim 1, wherein the upper straight portion of each of the supports is attached to a front face of the rod.

4. The set-up bar according to claim 1, further comprising one or more spacers mounted at predetermined intervals along the elongated rod.

5. The set-up bar according to claim 4, wherein each of the one or more spacers comprises a substantially V-shaped member having two legs extending from a base.

6. The set-up bar according to claim 5, wherein each of the one or more spacers is formed from rebar and the base is attached on a face of the elongated rod opposite the supports.

7. The set-up bar according to claim 4, wherein each of the one or spacers comprises a substantially straight member attached to the elongated rod and extending outwardly from the set-up bar and parallel to the supports.

8. The set-up bar according to claim 1, wherein the elongated rod is an elongated metallic rod.

9. A set-up bar for use in a rebar grid, the set-up bar comprising:

an elongated rod having a lower end, an upper end, a front face and a rear face;

a plurality of supports attached to the front face of the rebar at intervals and extending in the same direction, each support formed from a rebar or a steel rod and including a lower portion, an upper straight portion and an intermediate curved portion, the lower portion in combination with the intermediate curved portion forming a channel with an opening that faces the upper end of the elongated rod, the channel adapted to receive a rebar therein, and the upper straight portion is attached to the rod.

10. The set-up bar according to claim 9, further comprising one or more spacers mounted at predetermined intervals along a rear face of the elongated rod.

11. The set-up bar according to claim 10, wherein each of the one or more spacers comprises a substantially V-shaped member having two legs extending from a base or a substantially straight member attached to the rebar and extending outwardly from the set-up bar and parallel to the supports.

12. A rebar grid assembly comprising:

a plurality of set-up bars, each set up bar comprising;

an elongated rod having a lower end and an upper end;

a plurality of supports attached to the rebar at intervals, each support formed from a rebar or a steel rod and including a lower portion, an upper straight portion and an intermediate curved portion, the lower portion in combination with the curved intermediate portion forming a channel with an opening that faces the upper end of the elongated rod, the channel is adapted to receive a horizontal rebar therein, and the upper straight portion is attached to the rebar,

wherein the plurality of set-up bars are vertically oriented and aligned, and wherein the corresponding supports of the plurality of set-up bars are at substantially equal elevations and form a plurality of rows of supports;

a plurality of the horizontal rebars positioned in the plurality of rows of supports; and

a plurality of wire ties securing the plurality of horizontal rebars to the plurality of supports.

13. The rebar grid assembly according to claim 12, wherein each of the set-up bars further comprising one or more spacers mounted at predetermined intervals along a rear face of the rebar.

14. The rebar grid assembly according to claim 13, wherein each of the one or more spacers comprises a substantially V-shaped member having two legs extending from a base or a substantially straight member attached to the rebar and extending outwardly from the set-up bar and parallel to the supports.
