Benefits of technology
"The invention provides an apparatus for supporting and positioning rebar in a footing during concrete installation. The apparatus includes a triangular-shaped body with a reinforcement structure and at least one tie wire to secure the rebar. The apparatus also has a keyway and recessed depressions to hold the rebar, as well as a base to rest on the ground. The apparatus is made of a cement mixture and is designed to withstand high levels of reinforced steel. The technical effects of the invention include improved stability and protection of rebar during concrete installation, as well as reduced risk of shifting or crushing during concrete installation."
Problems solved by technology
The risk of the rebar support apparatus shifting or crushing during concrete installation is virtually non-existent.

Embodiment Construction
[0032] The solid, reinforced and pre-wired rebar support apparatus provides support and positioning for rebar in a footing. Such a support apparatus is also called a “rebar bench”. The rebar support apparatus can be fashioned to accept any orientation of rebar. FIG. 1 shows a side elevation view of the rebar support apparatus 1. Each rebar support apparatus 1 consists of one or more tie wires 4 wound to a reinforcement structure 3. The body of the rebar support apparatus 1 is formed of both fine and lightweight cement aggregates combined into cement mixture. Integrated into the rebar support apparatus 1 is sufficient reinforcement 3 to rate it as a structural beam. Also embedded into the rebar support apparatus 1 are tie wires 4 which determine proper location for rebar 5 in every direction. The rebar support apparatus 1 is a solid member with a reinforcement structure 3 and a tie wire 4 system that is completely protected from moisture migration. The risk of the footing rebar appar...

A solid, reinforced and pre-wired rebar support apparatus that supports, positions and firmly secures rebar in a footing. The apparatus comprises a body made of a cement mixture having a triangular shape that includes a reinforcement structure located centrally within the body and recessed depressions wherein rebar is to be seated and secured. Tie wires are wound around the reinforcement structure and embedded into the body of the apparatus. Portions of the tie wires emanate from either side of the depressions and are twisted around the rebar once the rebar is positioned to secure the rebar and prevent it from shifting during the concrete pour.
Description
FIELD OF INVENTION [0001] The invention relates generally to a solid, reinforced and pre-wired rebar support apparatus that supports, positions and firmly secures rebar in a footing. The apparatus is for use in supporting and securing rebar in the footings and foundations of buildings during a concrete pour. BACKGROUND OF THE INVENTION [0002] Rebar support structures of one type or another have been used for many years in the construction industry to hold panels or walls in fixed relation while concrete is poured. Most often, the rebar support contains twisted wire, which serves to hold the rebar securely in place. Previous attempts have been made to improve the rebar support structures, certain features of which are generally described in U.S. Pat. No. 6,883,289 to Juedes et al; U.S. Pat. No. 6,837,017 to Hardy, Jr. et al.; U.S. Pat. No. 6,732,484 to Sotelo et al.; U.S. Pat. No. 6,629,393 to Pignataro; U.S. Pat. No. 6,571,526 to Queen; U.S. Pat. No. 6,526,721 to Nash; U.S. Des. Pat...
