Prefabricated building sections or room units and methods for the manufacture of such sections or units

A method for the manufacture of a prefabricated panel for use in building comprising the steps of forming a frame by connecting at least two beam members, arranging a first plate on said frame by placing said frame in a jig with said beam members provided to surround the sides thereof and casting said first plate while in said jig surrounded by said beam members of said frame, arranging a second plate on said frame in a vertically parallel spaced relationship with said first plate, providing at least one tubular service conduit internally of at least one of said plates, forming said plates to define at least in part superimposed substantially identical openings adjacent one of said beam members and providing that said one beam member defines at least part of at least one of said openings, said plates being made from castable material which is cast contacting said one beam member, inserting a vertically disposed frame beam completely through both said openings defined by said plates and said one beam member, and rigidly securing said vertical frame beam to said one beam member.

A method for the manufacture of prefabricated building sections comprising making a panel and subsequently connecting at least one vertically disposed frame beam to that panel, wherein making the panel comprises the steps of forming a frame of beam members, arranging a first plate on said frame, arranging a second plate which is spaced vertically from said first plate on said frame and providing the panel with at least one tubular service conduit, providing an opening completely through said panel which is at least in part through said frame, the completed panel subsequently having said frame beam connected thereto by inserting the lower part of said frame beam through said opening for the entire vertical height of said panel, said frame beam comprising a central core and a surrounding sheath-like layer, said core being of metallic construction and the connection of said frame beam to the completed panel frame including the step of welding said metal core to at least one said beam member of said panel frame.

A method for the manufacture of prefabricated building sections comprising making a panel and subsequently connecting at least one vertically disposed frame beam to that panel, wherein making the panel comprises the steps of forming a frame of beam members, arranging a first plate on said frame,arranging a second plate which is spaced vertically from said first plate on said frame and providing the panel with at least one tubular service conduit, providing an opening completely through said panel which is at least in part through said frame, the completed panel subsequently having said frame beam connected thereto by inserting the lower part of said frame beam through said opening for the entire vertical height of said panel, said first and second plates of said panel being formed principally from cast concrete and being provided in the casting step with edges to define said opening through said panel.

A method for the manufacture of a prefabricated panel for use in building comprising the steps of forming a frame by interconnecting at least two beam members, arranging a first plate on said frame, arranging a second plate on said frame in a vertically parallel spaced relationship with said first plate, providing at least one tubular service conduit internally of at least one of said plates, forming said plates to define at least in part superimposed substantially identical openings adjacent one of said beam members and providing that said one beam member defines at least part of at least one of said openings, inserting a vertically disposed frame beam completely through said openings defined by said plates and said one beam member, and rigidly securing said vertical frame beam to said one beam member, said plates being made from castable material which is cast contacting one said beam member, and panel frame being laid in a jig with said beam members provided to surround the sides thereof, the material of which said first plate is cast in said jig being surrounded by said beam members of said frame, at least one rib and a layer of reenforcing mesh being arranged between said surrounding beam members of said panel frame before the material of said first plate is cast.

A method of manufacturing prefabricated building sections which comprises the steps of:

• making a panel with a hollow interior by forming a frame of metal channel beams with their vertically spaced horizontal limbs all extending inwardly, casting a first plate of concrete material which extends between and under the upper of said limbs and substantially covers the interior vertical portions of said channel beams, casting a second plate of concrete material which extends between and over the lower of said limbs and joins the portion of the first plate's casting covering the interior vertical portions of the channel beams whereby said first and second plates substantially cover the entire interior surface area of said channel beams, and providing in said casting steps a pair of similar openings, one of said openings in each said plates, which are in vertical register;
• placing a metal vertical frame beam in said openings and casting a hardenable material around said frame beam where it is received in said panel whereby a layer of concrete material is disposed substantially entirely between said frame and said frame beam on one hand and the hollow interior of said panel on the other.
