Abstract
Abstract A panel for use in the construction of composite concretereinforced walls, consisting of two parallel sheets of pressed composition material rigidly separated by metal rod members, with metal tabs projecting from the panel sheets to bear against similar adjoining panels, together with additional steel reinforcement members between the panel sheets. The interior spaces of the panel are filled with concrete which sets to form an interlocking composite wall structure of metal rod members, additional steel reinforcements, the external panel sheet and the concrete.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
A panel for use in the construction of composite concretereinforced walls, which panel becomes the permanent external surfaces of the finished composite wall, with consequent improvement in the attractiveness of the external wall surfaces, said panel consisting of two similar size sheets of pressed composition material, spaced a uniform distance apart from each other, in parallel planes, by metal rod members which are fastened to each of the panel sheets so as to form a rigid unit of the said two sheets and rod members., with a metal tab fastened to the rod member at the interior surface of each of said sheets and located so as to project beyond each said sheet in the plane of the sheet, said tabs adaptable to bear against the interior surfaces of the adjoining sheets of an adjoining panel of similiar construction, said tab being pivotably joined to the rod member so as to be free to rotate about said rod member, but is restricted from travel in the axial direction of the rod member.
Claim 2
Dependent Claim
172 words

Claim 3
Dependent Claim
36 words
A panel as described in claim 1 joined to similar adjoining panel by the projecting metal tabs so as to form a hollow wall prior to the addition of rEinforcing rods and the pouring of concrete.
Claim 4
Dependent Claim
57 words
A panel as described in claim 2 in which the interior of said panel contains additional steel members to serve as reinforcements, togehter with concrete which is poured into the interior sections of the panel and allowed to set in place, said concrete interlocking with the protruding metal tabs, said metal rod members, and said panel sheets.
