A prefabricated building panel to be used in constructing a building structure includes a generally planar concrete panel one surface and opposite surface also generally planar with a plurality of arrayed hooks couple through an insulation pad opposing hooks of a similar panel mostly mirrored to the first panel providing a cavity space being back filled with a foam insulation providing an lightweight foam core building panel with improved thermal isolation.

FIELD OF THE INVENTION  
       [0001]     The invention relates to concrete shapes used in construction or various structures. More particularly, it relates to panels providing walls and finished structures having increased strength over prior art to resist storms and earthquakes. Constructs derived from this building panel have improved thermal and insulation.  
       BACKGROUND INFORMATION  
       [0002]     Concrete blocks of the prior art are conventionally rectangular shapes having cavities extending from top to bottom through the blocks. These cavities are often filled with an insulation material to reduce the heat transfer. Often aligning features have been proposed to assist the workers in laying the block, however these are at an increased cost which makes these aids cost prohibitive and in the end skilled masonry workers prevail. Various mortarless interlocking blocks have been derived to facilitate construction of block walls and structures and the cost to benefit ratio works out so that it also is prohibitive.  
         [0003]     Block construction remains very much unchanged; applying mortar and laying block end to end then course on top of course with the set mortar providing the aligning feature to resist the blocks being displaced. When a catastrophe of sufficient forces to overcomes the mass loading and displaces these blocks more than a crack then the effected blocks must be reset or worse fall with crushing force. Much less dramatic shifting of the foundation is the most common reason that a building suffers occasionally a complete loss. The state of the art has shown this block construction to be non-compliant when the acting forces overcome the stiffness, then full recovery is not likely.  
         [0004]     While the proposed designs have shown blocks that require less skill to build with them and some even have improved thermal properties none are created by an outer panel and an inner panel joined by hooks insulated between the coupling surfaces. An approximate half pitch vertically staggered course joint is achieved by starting at the base with a half panel and likewise a staggered vertical joint line is achieved. None of the art seen has demonstrated these features.  
       SUMMARY OF THE INVENTION  
       [0005]     The present invention provides a panel having a specialized texture or natural finish planar surface and for special applications the surface might be curved. This generally rectangular surface has a substantially parallel opposite side with hook shaped protrusions with the body extending angularly with a tip segment at right angle to the body and a tip. The panel size determines the quantity, shape and arrangement to consider the load requirement of these hooks. In example, to cast the hooks of small panel because it is difficult to fill small features in a mold it would be preferable to produce them as continuous across the panel.  
         [0006]     The panel according to the present invention one method of manufactured will be by casting of concrete in a foam mold. At a manufacturing site a foam mold the rectangular size of the panel to be cast and having the intended hook and rib features created in the upper side is placed on a platen. Removable walls are closely fitted to all sides and extend above the top surface of the foam mold equal to the panel thickness to. This dammed area is filled with concrete level to the top of the walls and vibrated to fill all of the features of the mold. Prior to allow the concrete to set a finish surface or texture is applied. A finished panel is created when wall are removed and the mold material is cleared exposing the hooks. Another method of manufacturing construction panels is using a permanent mold in the mold process.
