Method and apparatus for manufacturing concrete panels and for constructing a wall with the panels
| Details |
Inventors: Hills, Craig A.;
Assignee:
Primary Examiner: Kent; Christopher
Assistant Examiner: Glessner; Brian E.
Attorney, Agent or Firm: Nissle, P.C.; Tod R.
A method and apparatus simplify the construction of a concrete panel to include openings through which rebar and concrete slurry extend in order to anchor the panel in a trench at a construction site to form a wall. The method and apparatus of the invention also reduce the likelihood that the panel will settle and damage the panel. |

DETAILED DESCRIPTION OF THE INVENTION Turning now to the drawings which depict the presently preferred embodiments of the invention for the purpose of describing the operation thereof and not by way of limitation of the scope of the invention and in which like reference characters refer to corresponding elements throughout the several views, FIG.
1 illustrates a concrete panel 10 constructed in accordance with the invention and including an upper portion, intermediate portion, and lower portion.
The upper portion has a flat planar front surface 21 and flat planar back surface 22.
The width of the upper portion is indicated by arrows WI in FIG.
1.
Rustications can, if desired, be formed in surfaces 21 and 22.
Surfaces 21 and 22 (or surfaces 24 and 25) need not be parallel to one another, but can taper (converge or diverge toward or away from one another) or can take on any desired shape and dimension.
The lower portion has a flat planar front surface 24 and a flat planar back surface 25.
The width of the lower portion is indicated by arrows W2 in FIG.
2.
The intermediate portion interconnects the upper and lower portions of panel 10 and includes canted flat planar surfaces 11 and 112.
Surface 11 interconnects parallel surfaces 24 and 21 and is at an angle G in the range of thirty to sixty, preferably forty-five, degrees with respect to planar surface 24.
Surface 112 interconnects parallel surfaces 22 and 25 and is at an angle T (FIG.
2) of thirty to sixty, preferably forty-five, degrees with respect to planar surface 25.
A plurality of spaced apart cylindrical apertures--including apertures 13, 14--extend completely through the lower portion of panel 10.
Each aperture 13, 14 presently has a diameter in the range of about one inch to six inches, preferably about three inches, and includes a cylindrical inner wall which circumscribes and bounds a cylindrical opening extending through the lower portion of panel 10.
Apertures 13, 14, etc.
are each presently spaced apart on one foot centers, but the spacing between apertures 13, 14, etc
