Abstract

A rebar support is provided through an arm-type apparatus, which may have a plurality of dimensions for different concrete constructions. A tube in the apparatus is slid over an upright support such as a grade stake to hold the apparatus in place. Multiple instances of the apparatus may thus be placed over multiple stakes to hold rebar in the correct position for the grid pattern required to strengthen the concrete in a particular structure. Rebar may then be quickly and securely snapped into notches on the apparatus without tying or extensive training of personnel. In an embodiment different designs of the apparatus are provided with notches designed to fit rebar of different diameters. In another embodiment snap-out tabs in the notches are used so that one design of the apparatus may be employed with rebar with different dimensions. The apparatus may be Y-shaped to further strengthen the arms.

Claims

1. An apparatus that holds rebar in place for forming the grid pattern used to strengthen concrete when the concrete is poured for construction, the apparatus comprising

at least two arms comprising a Y shape,

a hollow tube approximately center the at least two arms;

said hollow tube extending the height of the two arms;

the hollow tube operable to slide down over grade stakes

one or more notches located on the arms; and

at least one snap-out tab adjacent the one or more notches and operable to increase the size of the notch.

2. The central tube of claim 1, wherein the central tube comprises a plurality of apertures with dimensions that fit over a plurality of grade stakes with different dimensions.

3. The notches of claim 1, wherein the notches comprise

preformed notches with a plurality of diameters that fit a plurality of rebar with different diameters.

4. The notches of claim 1, wherein the notches comprise

semi-circular notches.

5. An apparatus that holds rebar in place for forming the grid pattern used to strengthen concrete when the concrete is poured for construction, the apparatus comprising

a device with arms, wherein the device with arms comprises a Y shape;

a central tube extending the height of the Y-shaped arms, wherein the central tube comprises an aperture that fits over a grade stake used in concrete construction; and

preformed notches, wherein the preformed notches comprise semi-circular notches; and

snap-out tabs operable to increase the size of the notches.

6. The central tube of claim 5, wherein the central tube comprises a plurality of apertures with dimensions that fit over a plurality of grade stakes with different dimensions.
