a second grid disposed adjacent the first side, the first cap and the second cap and the first grid and the second grid defining a frame which envelopes and holds the core without piercing through the core.
2 . The panel of claim 1 wherein the first grid is attached to the first cap and the second cap.
3 . The panel of claim 2 wherein the second grid is attached to the first cap and the second cap.
4 . The panel of claim 3 wherein the first cap has a c shaped cross section defined by a top web and a top first flange and a top second flange, with the top web disposed on the top of the core, the top first flange disposed on the first side, and the top second flange disposed on the second side.
5 . The panel of claim 4 wherein the second cap has a c shaped cross section defined by a bottom web and a bottom first flange and a bottom second flange, with the bottom web disposed on the top of the core, the bottom first flange disposed on the first side, and the bottom second flange disposed on the second side.
6 . The panel of claim 5 including mortar or concrete disposed on the first grid.
7 . The panel of claim 6 including a plurality of first bars disposed adjacent the first side; and a plurality of second bars disposed adjacent the second side, the first cap and the second cap and the first grid and the second grid and the first bars and the second bars defining a frame which envelopes and holds the core without piercing through the core.
8 . The panel of claim 7 wherein the first bars are attached to the first cap and the second cap.
9 . The panel of claim 8 wherein the second bars are attached to the first cap and the second cap.
10 . The panel of claim 9 wherein each first bar is attached to the top first flange and the bottom first flange.
11 . The panel of claim 10 wherein each second bar is attached to the top second flange and the bottom second flange.
