Invention herewith described refers to the prefabricated building structure built with prefabricated ferro-concrete ribbed element sandwich type cast in moulds. The invention is essentially all about new prefabrication of ferro-concrete elements (E) cast in special molds (K), by whose connection in an original way, the structures of building construction are built in the form of curved structures. Prefabricated ferro-concrete elements (E) are packed in special packages (P) and delivered by trailers onto the site. The essence of the solution lies in the fact that on the detachable two-part arc steel scaffold (3), with adjustable ends (4) fixed to the edges with construction adhesive, are placed two arched series of ferro-concrete elements (E) with a space left between for setting the steel reinforcement, closed from the outside and from the inside with formwork panels (7) interconnected by wire, in which is successively poured concrete to form the main bearing reinforced concrete arch (6) where are squeezed longitudinal reinforcements - whiskers (19) of ferro-concrete elements ( E), after which the formwork (7) and arch scaffolding (3) are removed. Prefabricated ferro-concrete ribbed element (E) sandwich type cast in a special mould (K) with a built-in vibrating motor consists of a box-shell (15) of ferro-concrete with reinforced ribs (16) a thermo-insulating layer (17) and the protective layer (5). The element (E) on the front sides has hooks (18) of reinforcement for removal the same from the mold (K) and positioning it on the site. Whiskers (19) of the reinforcement from the front side are used for its binding to the reinforcement of reinforced - concrete arches (6), and optionally have openings (8) for windows, ventilation and other installations.
