A prefabricated section for a building having a concrete slab floor with a concrete rim elevated relative thereto and spaced inboard a relatively short distance of the slab periphery. Walls are provided which are supported by metal beams which extend upwardly from the rim and have adjacent wooden beams. A ceiling member is provided which is supported by girders which are supported, in turn, by the metal beams. The girders also support the roof so that it is spaced a substantial distance above the ceiling. Insulation is provided immediately above the ceiling and against the inner wall sheets, the insulation being spaced from the roof and outer wall sheets. The upper ends of the metal beams have hoist connection members for receiving through closable openings in the roof hoisting cables and hooks for raising and moving the section. The walls, ceiling and roof are composed of materials which are light in weight compared to the concrete slab so that the center of gravity of the section is low. The concrete slab extends under the walls and the metal beams which support the walls are structurally connected to the slab either directly or through horizontal beams so that in hoisting the section via the beams, tension and compression stresses on the section are minimal.
A prefabricated box-shaped structural section which comprises a concrete slab floor with a vertically disposed periphery, at last two upright walls, and a ceiling member, said floor comprising a concrete slab and horizontally disposed structural metal beams surrounding and connected with at least the greater part of said periphery of said concrete slab, said floor slab being provided with a rim which is elevated relative to the remainder of the slab and is spaced a relatively short distance inboard of said periphery and is substantially parallel therewith, said walls joining said rim at least in part, said upright walls having at least two upright beams secured to said metal beams of said floor with their outer facing sides flush with said vertically disposed periphery, wall sheets mounted on opposite inner and said outer facing sides of said upright beams so that the beams are situated between the wall sheets, said wall sheets mounted on said outer facing sides of said upright beams overlapping and contacting said vertically disposed periphery, said walls being composed of a non-concretitious material providing a density substantially less than concrete and including between sheets a non-concretitious insulating material, the upper ends of each of said upright beams being connected with longitudinal and transverse beams provided to form with said upright beams and said horizontal metal beams a parallelepiped frame structure, a ceiling member being connected to said longitudinal and transverse beams, said ceiling member being composed of light weight non-concretitious materials whereby the section has a relatively low center of gravity.
A prefabricated box-shaped structural section which comprises a floor, at least two walls, and a ceiling member, said floor comprising a concrete slab, horizontally disposed structural metal beams surrounding at least a greater part of the periphery of said concrete slab, said concrete slab having a rim which is elevated relatively to substantially the entire remainder of said concrete slab, at least part of said walls joining said elevated rim, said walls being composed of a non-concretitious material providing a density substantially less than concrete, said walls having sheets on opposite inner and outer facing sides of upright beams provided in said walls so that the beams are situated between said wall sheets, the lower ends of said upright beams being connected to said horizontal metal structural beams of said floor, the upper ends of each of said upright beams being connected with longitudinal and transverse beams to form with said upright beams and said horizontal metal beams, a parallelepiped frame structure, a ceiling member being connected to said longitudinal and transverse beams, said ceiling member being composed of light weight non-concretitious materials whereby the section has a relatively low center of gravity.
A prefabricated box-shaped structural section which comprises a floor having a concrete layer and horizontally disposed structural metal beams including horizontal portions which are in part in said layer and which portions extend around at least a greater part of the periphery of said concrete layer, said layer being provided with a rim elevated relative to adjoining parts of said layer, at least two upright walls joining said rim, and a horizontal ceiling member, each said wall having at least two upright hollow beams rigidly secured to said horizontal portions of the corresponding of said horizontal structural metal beams, wall sheets mounted on opposite inner and outer facing sides of said upright beams, said upright beams being interconnected on the upper sides by girders, a horizontal roof structure, said ceiling member and said roof structure being substantially parallel throughout and connected to said girders whereby they are spaced apart throughout substantially their proximate horizontal areas, said wall sheets being composed of non-concretitious materials and being provided at opposite sides of said upright beams so that said upright beams are situated between said wall sheets.
A prefabricated box-shaped structural section which comprises a floor having a concrete slab and horizontally disposed structural metal beams including a horizontal portion thereof disposed around at least the greater part of the periphery of said concrete slab, said horizontal portion extending in said slab at least in part, at least two upright walls, upright beams, a ceiling member, and a roof structure, said slab including a rim which is elevated relative to the adjoining parts of said slab, said walls joining said elevated rim, each said wall including at least two of said upright beams which are rigidly secured to said horizontal portion of the corresponding of said horizontal structural metal beams, said upright beams being situated on the corners of said concrete slab, interior and exterior wall sheets mounted on opposite sides of said upright beams which are situated on the corners of said concrete slab, said exterior wall sheets extending over said upright beams and said horizontal portion, said upright beams being interconnected in their upper sides by girders, said ceiling member and said roof structure being connected to said girders, said upright beams extending above said ceiling member to proximate said roof structure and being provided above said ceiling member with a plurality of hoist connection members adapted for a connection to hoisting means for transport and vertical displacement of the section.
