Abstract

An apparatus for supporting reinforcement bar comprises a support assembly including a first support and a second support. The first support has a ground-engaging portion. The second support is coupled to the first support so that the ground-engaging portion provides subjacent support for the second support. The second support is structured and dimensioned to support a reinforcement bar in a substantially upright position. A support member is coupled to the support assembly. The support member is provided for vertically supporting another reinforcement bar. A method for supporting reinforcement bar comprises the steps of providing a ditch having a bottom surface and apparatus for supporting reinforcement bar. The method next comprises the step of positioning apparatus for supporting reinforcement bar in the ditch with an end of apparatus protruding from the ditch and a ground-penetrating portion driven in the bottom surface of the ditch. The method further comprises the step of coupling substantially horizontal reinforcement bars to support members of the apparatus. Upon completion of the foregoing steps, the method comprises the steps and of filling the ditch with suitable pour material so that the end of the apparatus protruding from the ditch remains exposed and allowing the concrete to harden. Once the concrete has hardened, a wall may be formed on the hardened concrete. The method comprises the final step of inserting substantially upright reinforcement bars into the apparatus.

Claims

1. An apparatus for supporting reinforcement bar, comprising:

a support assembly including;

a first support having a ground engaging portion; and

a second support coupled to the first support so that the ground engaging portion provides subjacent support for the second support, the second support being structured and dimensioned to support a reinforcement bar in a substantially upright position, the second support further including an opening for receiving the reinforcement bar therein and a penetrable cover blocking the opening; and

a lateral support member coupled to the support assembly for vertically supporting another reinforcement bar.

2. The apparatus of claim 1, wherein the support assembly and the lateral support member are hard plastic.

3. The apparatus of claim 1, wherein the support assembly and the lateral support member are metal coated with a water insoluble coating.

4. The apparatus of claim 1, wherein the second support is coupled to the first support by a coupling structure to permit the position of the second support to be adjusted relative to the first support.

5. The apparatus of claim 1, further comprising at least one clip supported by the lateral support member, the clip being structured and dimensioned to receive and hold the reinforcement bar supported by the lateral support member.

6. The apparatus of claim 1, further comprising filler for filling the second support to secure the reinforcement bar therein.

7. The apparatus of claim 1, wherein the cover includes a plug having a portion that is insertable in the opening of the second support and a penetrable surface covering the opening.

8. The apparatus of claim 6, wherein the filler is comprised of a resin and a hardener.

9. An apparatus for supporting reinforcement bar, comprising:

a support assembly including;

a standard having a ground penetrating portion; and

a receiver coupled to the standard for receiving a reinforcement bar and supporting the reinforcement bar in a substantially upright position, the receiver including an opening for receiving the reinforcement bar therein and a penetrable cover blocking the opening; and

at least one lateral support member coupled to the support assembly for vertically supporting another reinforcement bar.

10. The apparatus of claim 9, wherein the support assembly and the lateral support member are hard plastic.

11. The apparatus of claim 9, wherein the support assembly and the lateral support member are metal coated with a water insoluble coating.

12. The apparatus of claim 9, wherein the receiver is coupled to the standard by a coupling structured to permit the position of the receiver to be adjusted relative to the standard.

13. The apparatus of claim 9, further comprising at least one clip supported by the lateral support member, the clip being structured and dimensioned to receive and hold the reinforcement bar supported by the lateral support member.

14. The apparatus of claim 9, further comprising filler for filling the receiver to secure the reinforcement bar there, wherein the filler includes a resin and a hardener.

15. The apparatus of claim 9, wherein the cover includes a plug having a portion that is insertable in the opening of the receiver and a penetrable surface covering the opening.

16. The apparatus of claim 14, wherein the filler is comprised of a resin and a hardener.

17. An apparatus for supporting reinforcement bar, comprising:

a stake having opposite ends with a striking surface at one end and a piercing tip at the other end;

a sleeve coupled to the stake, the sleeve defining a chamber and having an open end and a closed end opposite the open end, the sleeve supporting at least one interference member in the chamber;

a cover blocking the open end; and

at least two vertically spaced transverse bars coupled to the sleeve.

18. The apparatus of claim 17, wherein the stake, sleeve and transverse bars are hard plastic.

19. The apparatus of claim 17, wherein the stake, sleeve and transverse bars are plastic-coated metal.

20. The apparatus of claim 17, wherein the sleeve is coupled to the stake by at least one collar attached to the sleeve and engageable with the stake, the collar having a threaded hole for receiving a threaded fastener that is engageable with the stake to releasably coupled the sleeve to the stake.

21. The apparatus of claim 17, further comprising at least one clip supported by each end of each transverse bar, the clip being structured and dimensioned to receive and hold a reinforcement bar.

22. The apparatus of claim 17, further comprising filler for filling the sleeve to secure a reinforcement bar therein, wherein the filler includes a resin and a hardener.

23. The apparatus of claim 17, wherein the cover includes:

a plug having a portion that is insertable in the open end of the sleeve;

a flange that abuts the end of the sleeve about the open end; and

a penetrable surface covering the open end.

24. The apparatus of claim 17, wherein the sleeve has a rectangular cross-section defined by four sides each having a plurality of tabs punched therein and folded inward of the sleeve so as to form a plurality of opposing interference members that cooperatively resist removal of a reinforcement bar from the sleeve.

25. A method for supporting reinforcement bar, comprising the steps of:

(a) providing a ditch having a bottom surface;

(b) providing a reinforcement bar support apparatus comprising;

a support assembly having a ground penetrating portion coupled thereto; and

at least one lateral support member coupled to the support assembly; and

(c) positioning the apparatus in the ditch with an end thereof protruding from the ditch and the ground penetrating portion driven into the bottom surface of the ditch.

26. The method of claim 25, further comprising the step of:

(d) coupling a substantially horizontal reinforcement bar to the lateral support member.

27. The method of claim 26, further comprising the steps of:

(e) filling the ditch with pour material so that the end of the apparatus protruding from the ditch remains exposed; and
