Buildings formed by one or more prefabricated building sections, and method of manufacturing prefabricated building sections

A building comprising at least one prefabricated box-shaped building section enclosing at least part of the building's living area, said section having at least one vertically disposed rectangular wall which comprises a single slab of cast concrete, metal frame beams at least in part surrounding the outer periphery of said slab including the vertical edges thereof and joining the peripheral edges of said slab substantially over said slab's entire thickness, said slab including a plurality of stiffening bars embedded therein which are each inclined relative to each said metal frame beam and which are proximate to but not touching and spaced from said frame beams at each corner of said slab.

A building comprising at least one prefabricated box-shaped building section which encloses at least part of the building's living area, said section being elongated and having only one vertically disposed rectangular wall at each shorter end of said section, each said wall comprising a single slab of cast concrete having a uniform thickness substantially throughout, metal frame beams included in said wall at least in part surrounding the outer periphery of said slab, each said slab including a plurality of stiffening bars embedded therein, all of said stiffening bars being inclined relative to each of said frame beams surrounding the outer periphery of each said wall, the end portion of each said stiffening rod being proximate but not touching at least one of said frame beams.

A building comprising at least one elongated prefabricated box-shaped building section which encloses at least part of the building's living area, said section having a wall at one shorter end thereof which is comprised of only a single slab of concrete which is surrounded at least in part by a framework of metal beams, a plurality of stiffening bars embedded in said slab, all of said stiffening bars being inclined relative to each of said metal beams, the end portions of each said stiffening bar being located proximate the periphery of said slab, said end portion of each said stiffening rod being located proximate to but separated from a said metal beam.

A building comprising at least one elongated prefabricated box-shaped building section which encloses at least part of the building's living area, said section having a wall at one longer end thereof which is comprised of only a single slab of concrete which is surrounded at least in part by a framework of metal beams, at least two horizontally spaced openings for receiving a window or door in said slab, a plurality of stiffening bars embedded in said slab, said stiffening bars being provided between said openings in said slab and between each said opening and a vertical edge of said slab which are inclined relative to said metal beams, a further stiffening bar embedded in said slab, said further stiffening bar arranged to extend over both said openings.

A building comprising box-shaped prefabricated sections which enclose at least part of the building's living area, said sections having at least two adjoining vertically disposed rectangular walls each of which comprises a single slab of concrete having a uniform thickness substantially throughout, a framework of metal beams included in each said wall for each said slab, said metal beams joining and substantially surrounding each said slab, vertical metal beams of each said framework in each said wall in an adjoining relationship where said walls adjoin, each said vertical beam covering the entire vertical edge of the corresponding slab, each said slab including a plurality of stiffening bars embedded therein which are inclined relative to said metal beams, end portions of said stiffening bars being proximate to but not touching said frameworks, each said wall comprising a first layer composed of an insulating material covering said slab and said framework and a second protective layer outside said first layer.

A building comprised of a plurality of prefabricated elongated box-shaped sections, each said section having a framework of metal beams whereby the walls of said sections each have a surrounding framework of metal beams at the periphery thereof, each said wall composed of a cast material, stiffening bars encased in each said wall, said stiffening bars being entirely spaced from and inclined relative to the beams of said framework and having an end portion proximate to a corner of each wall but not touching said beams, said corner being defined by said framework, at least two of said inclined stiffening bars intersecting each other in each said wall.

A building comprising a plurality of prefabricated box-shaped sections, each said section having a framework or horizontal and vertical metal beams whereby the walls of said sections each have a framework of metal beams at the periphery thereof, at least one of said walls being of a uniform thickness substantially throughout and composed of a cast material, a rectangular opening through said cast material for a passageway in said wall, said opening having at least two of its sides defined by said metal beams of said framework and the other two sides defined by said cast material, stiffening bars entirely encased in said one wall, each of said stiffening bars being inclined relative to both said vertical beams and the horizontal beam, each corner of said opening which is defined at least in part by said cast material having proximate thereto a portion of one of said inclined stiffening bars.

A building comprising at least one prefabricated, box-shaped building section enclosing at least part of a living area and having at least one vertically disposed wall, said wall comprising a single slab only which is composed of cast concrete material and is provided with crossed stiffening bars, metal frame beams provided at the outer periphery only of said slab which at least in part surrounds said slab, each said stiffening bar being inclined relative to the horizontal and to each of the circumferential edges of said wall, said frame beams joining said slab substantially throughout said slab's thickness, each said stiffening bar being wholly spaced from said frame beams.

A building comprising at least one prefabricated box-shaped building section enclosing at least part of a living area and having at least one vertically disposed wall, said wall comprising a single slab only which is composed of cast concrete non-layered material and is provided with crossed stiffening bars, which are substantially completely embedded in said concrete material, metal frame beams provided at the outer periphery only of said slab which at least in part surround that slab, said stiffening bars each being inclined relative to the horizontal and not touching and spaced from said metal beams.
