Abstract
Abstract A unitized framework of steel beams with reinforcing rods and stiffening brackets welded throughout, and made completely rigid by casting concrete within the framework and bonding the concrete to the framework, provides a rigid panel that approximates the characteristics of a reinforced concrete plate while requiring less concrete and less steel than prior art panels for equal load conditions. The steel and concrete plate is constructed by arranging steel members into a framework, the size and shape of the desired plate, and welding adjacent metered ends of the members together. Added framework rigidity is provided by welding stiffening steel members at each corner. A plurality of reinforcing rods, spaced apart, extend from one side of the framework to the other. The reinforcing rods are first welded to a spacer bar having predetermined holes slightly larger than the rods and are then welded to the steel members. Added lateral support is provided for the reinforcing rods by welding several additional rods to the opposite sides of the framework substantially perpendicular to the first set of reinforcing rods. The rigid plate construction is finalized by casting concrete into the steel framework which is previously prepared with a mounting agent. The resulting unitary steel and concrete plate requires less concrete and less steel than normal panels when subjected to equal loads.
