Technical Specifications for the AAA Three Dimensional Panel System

 

The shop-fabricated AAA Three Dimensional Panels consist of a three dimensional welded wire space frame utilizing a truss concept for stress transfer and stiffness. Each surface of the wire space frame has a 2 inch square welded mesh (11 gauge galvanized) pattern of longitudinal and transverse wires of the same diameter.

Individually welded internal strut wires (9 gauge alvanized) or diagonals extend through the panel core between each surface. These galvanized strut wires are welded continuously in the required spacing so they form, with the welded wire fabric, into a triangulated truss system which greatly increases the panel strength.

When welded in place, these strut wires pierce through a modified expanded polystyrene core placed between the two layers of welded wire fabric, maintain the required distance apart and provide the shear transfer between the panel surfaces.

The modified expanded polystyrene core (minimum density 0.9 pounds per cubic foot) is held 1/2" or 3/4" from each face of the wire frame to permit the wire to be embedded in an application of approximately 1" - 2" thick concrete mixture with 2,500 psi minimum.

Conduit, Breaker Panels and Utility boxes are cut into panels

Wind Load Data

Above wind load curves are based upon final in-place wind loads and should be used as a starting point to determine the panel thickness when Insteel is used between two concrete layers of equal thickness. Each curve represents the use of with various amounts of additional reinforcing and insulation. The distance between the floor support and the roof support is considered the "span." No intermediate supports are considered.
