An insulated wall construction is formed of a pair of parallel, spaced apart foam plastic sheets and a poured-in-place concrete core filling the space between the sheets. The sheets are each formed of numerous smaller panels which are interconnected edge to edge to form their respective sheets. The sheets are secured together, before the concrete is poured, by means of numerous metal tie members. Each tie member is formed of a pair of parallel, elongated, thin, rigid sheet metal plates which are interconnected by thin, narrow, elongated sheet metal strips whose opposite ends are connected to the respective plates and with the strips being twisted along their lengths. Each of the plates are inserted within aligned edge pockets formed in the abutting edges of adjacent panels which assists in aligning and interconnecting the panels. The plates carry tooth-like clips which embed within the pocket walls to hold the panels from moving, due to hydrostatic forces, during the concrete pouring. The plates and the stirps dissipate heat, such as caused by fire, to increase the fire resistance and the insulation capacity of the wall construction.

An insulated wall construction comprising: a pair of parallel, spaced apart, foam plastic sheets, each formed of numerous smaller panels that are engaged together edge to edge to form a sheet; a poured and cured in place concrete core filling the space between the sheets to form a composite plastic-concrete-plastic structure; aligned pockets formed in at least some of the engaged edges of adjacent panels, each pocket having an open slot formed through the wall surface into the interior of the pocket and facing toward the opposing panel; tie members for interconnecting and immobilizing the panels and the sheets during the pouring and curing of the concrete, with said tie members each comprising a pair of elongated, thin, rigid sheet metal plates having opposite surfaces, said plates are sized and shaped to snugly fit into a pair of aligned edge pockets, and a number of thin, narrow, sheet metal strips having opposite ends and extending between each pair of plates, with the opposite ends of the strips extending through the pocket slots into the pockets and connected to the plates; a portion of the opposite ends of each of the strips being bent into a U-shape having at least two legs and a bight, with the legs of the U-shape at right angles to an initial plane of each strip, and with the bight of the U-shape extending through a corresponding slot formed through the plate so that the legs are arranged parallel to the opposite surfaces of the plate; said legs being secured together and to the plates by means of mechanical fastener means, such as a rivet, extending through the legs and portions of the plate which the legs overlie; and tooth members carried by the plates for embedding into the plastic panels adjacent thereto; wherein the tie members rigidly hold the panels in position prior to and during the pouring of the concrete, thereby forming a casting mold for the concrete, and mechanically fasten the panels and concrete core together, and further, rapidly dissipate heat, such as due to fire, applied to one surface of the wall, into the concrete core for increasing the heat resistance and insulation capacity of the wall.
