Claims: What I claim is: 1. A method for the manufacture of prefabricated building sections on a production line, the method comprising the steps of producing prefabricated panels in a manufacturing part of the production line, making such panels which are intended for use as floor panels and ceiling or roof panels in an elongated rectangular shape in said manufacturing part while being maintained in a predetermined relative orientation, storing said floor panels and ceiling or roof panels in substantially said predetermined relative orientation proximate said production line, conveying said floor panels and ceiling or roof panels while substantially in said predetermined relative orientation to a location beside an assembly station, conveying said floor panels and said ceiling or roof panels to said assembly station while maintaining them in said predetermined relative orientation, assembling said prefabricated panels in at least one assembly jib at said assembly station while arranging and holding said panels in said jig in substantially said predetermined relative orientation, securing said floor panels and said ceiling or roof panels and wall panels to one another in said jig, said floor panels and said ceiling or roof panels being substantially in said predetermined relative orientation while and immediately after being so secured to form the sections in a basically completed structural condition, and moving said basically completed structural sections out of said assembly jig for finishing operations on a further part of the production line. 2. A method for the manufacture of prefabricated building sections on a production line, the method comprising the steps of producing prefabricated panels in a manufacturing part of the production line, making such panels which are intended for use as floor panels and ceiling or roof panels in an elongated rectangular shape in said manufacturing part while being maintained in a predetermined relative orientation, storing said floor panels and ceiling or roof panels in substantially said predetermined relative orientation proximate said production line, conveying said floor panels and ceiling or roof panels while substantially in predetermined relative orientation to a location beside an assembly station in a direction parallel to the longer sides of said floor panels and said ceiling or roof panels, conveying said floor panels and said ceiling or roof panels to said assembly station while maintaining them in said predetermined relative orientation in a direction substantially perpendicular to said longer sides of said panels, assembling said prefabricated panels in at least one assembly jig at said assembly station while arranging and holding said panels in said jib in substantially said predetermined relative orientation, securing said floor panels and said ceiling or roof panels and wall panels to one another in said jig, said floor panels and said ceiling or roof panels being substantially in said predetermined relative orientation while and immediately after being so secured to form the sections in a basically completed structural condition, and moving said basically completed structural sections out of said assembly jig for finishing operations on a further part of the production line. 3. A method for the manufacture of prefabricated building sections on a production line, the method comprising the steps of producing prefabricated panels in a manufacturing part of the production line, making such panels which are intended for use as floor panels and ceiling or roofs panels in an elongated rectangular shape in said manufacturing part, the floor members including a rectangular framework of metal beams, casting a concretive material in said framework while said framework is in a horizontal position, drying and hardening said material in said framework which thereby becomes affixed to said framework, storing said floor panels and ceiling or roof panels, conveying said floor panels and ceiling or roof panels to a location beside an assembly station in a direction parallel to the longer sides of said floor panels and said ceiling or roof panels, conveying said floor panels and said ceiling or roof panels to said assembly station in a direction substantially perpendicular to said longer sides of said panels, assembling said prefabricated panels in at least one assembly jig at said assembly station while arranging and holding said panels in said jig, securing said floor panels and said ceiling or roof panels and wall panels to one another in said jig, said floor panels and said wall panels and said ceiling or roof panels being secured to form the sections in a basically completed structural condition, and moving said basically completed structural sections out of said assembly jig for finishing operations on a further part of the production line. 4. A method for the manufacture of prefabricated building sections on a production line, the method comprising the steps of producing prefabricated panels in a manufacturing part of the production line, making such panels which are intended for use as floor panels and ceiling or roof panels in an elongated rectangular shape in said manufacturing part, storing said floor panels and ceiling or roof panels, conveying said floor panels and ceiling or roof panels to a location beside an assembly station in a direction parallel to the longer sides of said floor panels and said ceiling or roof panels, conveying said floor panels and said ceiling or roof panels to said assembly station in a direction substantially perpendicular to said longer sides of said panels, assembling said prefabricated panels in at least one assembly jig at said assembly station while arranging and holding said panels in said jig, securing said floor panels and said ceiling or roof panels and wall panels to one another in said jig, said floor panels and said ceiling or roof panels being secured to form the sections in a basically completed structural condition, and moving said basically completed structural sections out of said assembly jig for finishing operations on a further part of the production line. 5. A method as claimed in claim 4, wherein the prefabricated building sections are assembled individually in said assembly jig. 6. A method as claimed in claim 4, each said section being moved from said assembly jig to said further part of the production line in a direction substantially parallel to said section's longer sides. 7. A method as claimed in claim 6, wherein said section is moved through said further part of the production line in a direction substantially parallel to said section's longer sides. 8. A method as claimed in claim 4, wherein the prefabricated panels are conveyed from at least one storage area at one side of said assembly jig to said assembly jig in a direction transverse to the length of the production line. 9. A method as claimed in claim 4, wherein the assembly station comprises at least two separate rows of assembly jigs, each said row comprising at least two assembly jigs, each row extending substantially parallel to the direction in which assembled sections are moved from said station to said further part of the production line. 10. A method as claimed in claim 4, wherein the prefabricated panels are made in a manufacturing part of the production line, the panels intended for use as floor panels and ceiling or roof panels being made in said manufacturing part in substantially the same relative orientation they will subsequently occupy in said assembly jig. 11. A method as claimed in claim 10, wherein said metal beams are welded to one another in an assembly station comprising said assembly jig to form said building sections. 12. A method as claimed in claim 4, wherein said further part of the production line comprises means for supporting at least two separate rows of building sections for movement therealong. 13. A method as claimed in claim 12, wherein means are provided for moving building sections of each said row independently of the other said row. 14. A method as claimed in claim 4, wherein materials, apparatus, appliances and the like for use in the finishing of said building section are supplied to the further part of the production line from supply facilities located at at least one side of that part. 15. A method as claimed in claim 4, wherein said building section is moved from said assembly jig to the destination end of said further part of the production line along a substantially straight path. 16. A method as claimed in claim 4, wherein the prefabricated panels are fed to an assembly station comprising said assembly jig from two opposite sides of said assembly station. 17. A method for the manufacture of prefabricated building sections which comprise the steps of manufacturing panels to comprise floor, wall and ceiling or roof members of the sections, the floor members including a rectangular framework of metal beams, said metal beams comprising two pairs of parallel beams, casting a concretive material in said framework while said framework is in a horizontal position, drying and hardening said material whereby it becomes affixed to said framework, thereafter assembling said members into a basic building section structure, placing said structure on an assembly line wherein two parallel beams comprising one said pair of said parallel beams of said framework bear directly on two spaced lines each comprising a plurality of supporting rollers, rolling said structure along said assembly line by moving means applying force directly to a rear metal beam of said framework other than said two parallel metal beams of said framework while maintaining said structure in its desired lateral orientation by guide means which extend longitudinally along each said spaced line of supporting rollers and are proximate said two parallel metal beams of said framework whereby all moving contacts occurring between said structure and said assembly line are directly via said framework. 18.
