A method as claimed in claim 1, wherein said prefabricated panels are provided by conveyor lines to said assembly station from two opposite sides of said station. 12. A method as claimed in claim 11, wherein said panels are provided to said assembly station from storage areas in which areas some drying, setting or hardening of the material of said panels takes place. 13. A method as claimed in claim 12, wherein said panels are made in a manufacturing part of said production line and are conveyed from that part to at least one storage area adjacent said assembly station. 14. A method as claimed in claim 13, wherein said panels are moved to said storage area by conveying members arranged to move over and above said manufacturing part of said production line. 15. A method as claimed in claim 14, wherein said panels are moved from said storage area to said assembly station by means of said conveying members for said panels. 16. A method as claimed in claim 15, wherein said panels are made in jigs provided along said manufacturing part of said production line. 17. A method as claimed in claim 16, wherein at least some of said panels are formed pricipally from slabs of castable material, and wherein a metal beam is provided along at least one edge of each such slab. 18. A method as claimed in claim 17, wherein said castable material is concrete. 19. A method as claimed in claim 18, wherein means is provided for heating said castable material and said material is conveyed to casting jigs in said manufacturing part in a hot condition. 20. A method as claimed in claim 17, wherein said concrete is prepared in a mixing area and is provided said manufacturing part of said production line by a conveyor belt, further conveying means being provided for moving the castable material from the conveyor belt to individual and casting jigs of said manufacturing part. 21. A method as claimed in claim 17, wherein at least some of said jigs in which at least parts of the panels are cast are provided with means for moving them from substantially horizontal positions into substantially vertical positions, and wherein, after a panel has hardened to an extent sufficient to permit its removal from the corresponding jig, that jig is brought to its substantially vertical position and the panel is engaged by conveying means so that it may be transported in a substantially vertical position by that conveying means from said manufacturing part of said production line to said storage area. 22. A method as claimed in claim 13, wherein said floor panels and ceiling or roof panels are transported from said manufacturing part of said production line to said storage area in dispositions which are substantially identical to those in which they were cast. 23. A method as claimed in claim 13, wherein at least some of said panels are provided on said manufacturing part of said production line with corresponding frames, said frames being made in at least one jig in a construction part of said production line. 24. A method as claimed in claim 23, wherein said frames are formed from metal beams which are welded together in said jig. 25. A method as claimed in claim 24, wherein said metal beams are subject to an antioxidizing treatment prior to their use in said jig in which said prefabricated panels are made. 26. A method as claimed in claim 25, wherein said antioxidizing treatment is effected by dipping said metal beams in at least one bath of a liquid oxidizing protective agent. 27. A method as claimed in claim 1 comprising the initial step of manufacturing panels for the floors of said sections of concrete material cast within a framework of metal beams which is incorporated in each said floor panel as its outer periphery, and subsequently utilizing said frameworks of metal beams in moving said structural sections by said conveying mechanism whereby said framework is employed for the connection between said conveying mechanism and each said section. 28.
