<p>A precast panel for a building comprises a pair of molded concrete inner and outer panel elements with a steel wire mesh embedded throughout each panel element. A series of laterally spaced continuous steel rod trusses are interposed between and extend at right angles to the panel elements with end portions of the trusses embedded into the panel elements. An insulating layer overlies and is bonded to the interior side of the outer panel element occupying part of the space between the panel elements, the remainder of the space providing an air barrier zone. Pairs of aligned panels and right angularly related corner panels are interconnected by a concrete column poured in situ between the adjacent panels. The method of making the building panel includes the steps of assembling and interconnecting a series of wire trusses between a pair of wire mesh reinforcements forming a reinforcement member, supporting the reinforcement member upon a first mold, pouring concrete into the mold to enclose one steel wire mesh reinforcement and the one edge portions of the trusses, and curing to form a reinforced inner panel element with one of the wire mesh and portions of the trusses embedded therein. Further steps include applying and bonding series of strips of insulating material between the trusses in a plane spaced from the inner panel element and mounting the inner panel element, reinforcement and insulating strips horizontally with the insulating strips forming the bottom of a second mold and successively pouring concrete into the second mold enclosing the other wire mesh reinforcement and other edge portions of the trusses and curing to provide a unit building panel.</p> |
