Abstract

A steel placement member adapted for supporting and locating a reinforcing steel bar in a concrete structural member formed by placing concrete in an area defined by a horizontal bottom surface and a vertical perimetrical surface. The steel placement member is defined by a tubular body having a channel formed in one end for receiving the end of a reinforcing bar. The opposite end of the tubular body is provided with a plate member lying perpendicular thereto and being adapted to abut the vertical perimetrical surface. According to a preferred embodiment of the invention, the plate member is provided with a vertically depending arrow member which is adapted to rest against the horizontal bottom surface. The steel placement member, with the plate member abutting the vertical surface and the arrow member resting against the bottom surface, supports the reinforcing bar within the channel and locates the reinforcing bar a desired distance inside the vertical surface and above the bottom surface.

Claims

1. A steel placement member adapted to support and position a reinforcing steel bar in a concrete structural member formed by placing concrete within an area defined by a bottom horizontal surface and a vertical perimetrical surface comprising a tubular body having a first end, a second end, and a longitudinal axis, a generally circular channel formed in said first end of said body, said channel being defined in said tubular body by an inside diameter and an outside diameter, a generally planar plate member provided on said second end of said body, said plate member being located in a plane perpendicular to said longitudinal axis and having a back surface, said back surface being adapted to abut said vertical perimetrical surface, said plate member being defined by first, second, third and fourth corners, said first corner being disposed directly above said tubular body, said second and third corners being disposed directly one on each side of said tubular body, said fourth corner being disposed directly below said tubular body, said fourth corner being provided with an integral vertically depending arrow member, said arrow member having a tip adapted to rest against said horizontal bottom surface, said arrow member having a length, as measured by the distance from said channel to said tip, for holding said reinforcing bar a desired distance above said bottom surface when said back surface of said plate member abuts said vertical surface, said channel being adapted to receive an end of said reinforcing steel bar, said channel having a depth so as to support said end of said reinforcing steel bar a desired distance inside said vertical surface.

2. A steel placement member adapted to support and position a reinforcing steel bar in a concrete structural member formed by placing concrete within an area defined by a bottom horizontal surface and a vertical perimetrical surface comprising an integral tubular body defined by a first end, a second end, a generally planar plate member provided on said second end perpendicular to said tubular body, said plate member having a back surface, said tubular body being further defined by a continuous outer diameter surface, a continuous inner diameter surface extending from said first end toward said second end but being interrupted by a partition located within said tubular body between said first and said second ends of said tubular body, said inner diameter surface and said partition together defining an enclosed circular channel having an open end coincident with said first end and a closed end coincident with said partition, said back surface of said plate member being adapted to abut said vertical perimetrical surface, said channel being adapted to receive an end of said reinforcing bar through said open end of said channel, said reinforcing bar being adapted to be disposed in said channel such that said end of said bar abuts said partition, said closed end of said channel being located with respect to said back surface of said plate member such that said end of said bar abutting said partition is positively held within said channel a specified distance inside said vertical surface, said back surface of said plate member being adapted to be located at a specified vertical height above said horizontal bottom surface.

3. The steel placement member recited in claim 2 wherein said channel is adapted to be formed of diverse inside diameters, said inside diameters corresponding to a size of reinforcing steel bar.

4. The steel placement member recited in claim 3 wherein said steel placement member is adapted to be color-coded according to said inside diameter of said channel.

5. The steel placement member recited in claim 2 wherein said steel placement member is formed as an integral molding from styrene.

6. The steel placement member recited in claim 2 wherein said steel placement member is formed as an integral molding from polyethylene.

7. The steel placement member recited in claim 2 wherein said plate member is defined by first, second, third and fourth corners, said first corner being disposed directly above said tubular body, said second and third corners being disposed directly one on each side of said tubular body, said fourth corner being disposed directly below said tubular body.

8. The steel placement member recited in claim 7 wherein said first, second and third corners are each provided with an outwardly tapering through hole, each of said through holes being adapted to receive means for securing said steel placement member to said vertical perimetrical surface.

9. The steel placement member recited in claim 7 wherein said fourth corner is provided with an integral vertically depending arrow member, said arrow member having a tip adapted to rest against said horizontal bottom surface, said arrow member having a length, as measured by the distance from said channel to said tip, for holding said reinforcing bar a desired distance above said bottom surface when said back surface of said plate member abuts said vertical surface.

10. The steel placement member recited in claim 2 wherein said plate member is generally circular, being larger in diameter than said outside diameter of said tubular body.

11. The steel placement member recited in claim 2 wherein said specified distance inside said vertical surface is at least two inches.

12. A steel placement member adapted to support and position a reinforcing steel bar in a concrete structural member formed by placing concrete within an area defined by a horizontal bottom surface and a vertical perimetrical surface comprising a tubular body having a first end, a second end, and a longitudinal axis, a generally circular channel formed in said first end of said body, said channel being defined in said tubular body by an inside diameter and an outside diameter, a generally planar plate member provided on said second end of said body, said plate member being located in a plane perpendicular to said longitudinal axis and having a back surface, said plate member being defined by first, second, third and fourth corners, said first corner being disposed directly above said tubular body, said second and third corners being disposed directly one on each side of said tubular body, said fourth corner being disposed directly below said tubular body and being provided with an integral vertically depending arrow member having a tip, said back surface of said plate member being adapted to abut said vertical perimetrical surface, said tip being adapted to rest against said horizontal bottom surface, said channel being adapted to receive an end of said reinforcing bar, said channel having a depth so as to support said end of said reinforcing bar a desired distance inside said vertical surface, said arrow member having a length, as measured by the distance from said channel to said tip, for holding said reinforcing bar a desired distance above said bottom surface when said back surface of said plate member abuts said vertical surface.

13. The steel placement member recited in claim 12 wherein said first, second and third corners are each provided with an outwardly tapering through hole, each of said through holes being adapted to receive means for securing said steel placement member to said vertical perimetrical surface.

14. The steel placement member recited in claim 12 wherein said plate member is generally square.

15. The steel placement member recited in claim 12 wherein said channel is adapted to be formed of diverse inside diameters, said inside diameters corresponding to a size of reinforcing steel bar.

16. The steel placement member recited in claim 15 wherein said steel placement member is adapted to be color-coded according to said inside diameter of said channel.
