Title: Prefabricated multi-layer steel-reinforced concrete panels

Abstract: A sandwich panel assembly or slab structure has a pair of steel-reinforced concrete plates generally coextensive with one another and a cushion of insulating foamed synthetic resin therebetween. A tubular anchor is located at the center (centroid) of at least a portion of the panel and is embedded in the concrete plates. At least one slightly flexible elongated auxiliary anchor plate or membrane sheet provides additional fixation of the assembly. This membrane is spaced from the tubular anchor and traverses the resin cushion and is embedded in each of the concrete plates. Metal bars extend through and from the membrane and are embedded in the concrete plates.
