Benefits of technology
[0006]The present disclosure is directed to an apparatus and method for reinforcing concrete using rebar. For purposes of summarizing the disclosure, certain aspects, advantages, and novel features of the disclosure have been described herein. It is to be understood that not necessarily all such advantages ma
Problems solved by technology
The traditional method is deficient in several ways.
First, the wire cages are susceptible to bending and deformation leading to poorly placed rebar and a weaker concrete structure.
Second, many rebar chairs are constructed from multiple pieces that may require welding and other preparation or maintenance, causing increased cost and construction time.
Furthermore, the traditional method often times requires two or more workers to successfully install the rebar chairs, also causing increased cost and construction time.
Finally, the wire tied rebar intersections do not prevent angular deflection, possibly leading to a weaker concrete structure.

Embodiment Construction
[0018]The various embodiments of the present disclosure and their advantages are best understood by referring to FIGS. 1 through 6 of the drawings. The elements of the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the disclosure.
[0019]Each construction project will dictate the design of the rebar lattice work needed to reinforce the concrete used in the project. The rebar lattice design must take into account the height and spacing of each piece of rebar, and its placement throughout the concrete structure. Once the design of the lattice work has been determined, the rebar support devices of the present disclosure are strategically placed to retain the rebar in the desired locations, and at the appropriate height and spacing.
[0020]FIGS. 1-3 illustrate one embodiment of a rebar support device 105. In this embodiment, the rebar support device 105 comprises a generally planar support plate 190 that is oriented in a gene...

A rebar support device for retaining rebar in a position for reinforcing concrete, and method of using the same is claimed. The rebar support device comprises at least one concrete bonding opening dispersed throughout, at least one rebar support chase with bendable retaining gates, and at least one grade stake support hole. The rebar support device is held in a vertical position for receiving rebar by driving a grade stake through the stake support holes, such that the rebar support device is disposed perpendicularly to the rebar it receives. The rebar is then cradled in one or more of the support chases and retained by a bendable retaining gate incorporated into each rebar support device above each support chase.
Description
REFERENCE TO RELATED APPLICATION[0001]This application claims priority to U.S. Provisional Patent Application Ser. No. 60 / 890,681, entitled “Rebar Holding and Positioning Apparatus and Method for Reinforcing Concrete Using Rebar,” filed on Feb. 20, 2007, which is fully incorporated herein by reference.FIELD OF THE INVENTION[0002]The present disclosure relates generally to the field of concrete reinforcement. In particular, the present disclosure relates to a rebar holding and positioning apparatus and a method for reinforcing concrete using rebar.BACKGROUND OF THE INVENTION[0003]Many construction projects require concrete which incorporates reinforcing bar (“rebar”) lattice work for the purpose of adding strength and resisting slab failure should cracks develop. In order to effectively perform this function, the rebar lattice must retain its rectangular lattice shape, and it must be strategically placed—often times suspended near the center of the concrete structure. Current methods...
