A structural element constituting a panel for a floor, wall or roof of a space defining elongated box-shaped prefabricated section which includes a rectangular concrete slab with a peripheral rectangular frame of beams. A reinforcement network is attached to the frame beams. With I-beams constituting the frame beams, one side of an upper flange is cast within the slab, such flange being connected to the reinforcement network. Recesses are provided at the corners of the slab to receive upright extensions affixed to the top of the upper flanges of the I-beams, such extensions being adapted to receive for attachment columns or other components of the section. The recess provided for the extensions may be spaced therefrom and being filled in with a concrete or other plastic type material when the further component is received on the extension. The extension may extend above the slab without a recess. A covering material may be applied to the top of the slab and folded over its edges. An L-shaped edge piece may be connected to the slab at its upper edges, the vertical leg of the edge piece extending to the exposed edges of the upper flanges of the I-beam and the horizontal leg of the edge piece extending inwardly and being flush with the top surface of the slab. An angle piece member may be connected to the slab at its edges so it is received on top of the upper flange of the I-beam and its vertical portion extends upwardly from the exposed edges of the upper flanges of the I-beam. A further alternative is to furnish a wooden border member with its top flush with the top surface of the slab. Another alternative is to place a wooden beam on top of the slab which is rigidly connected to the I-beam, such wooden beam having a wall affixed thereto. Further, transverse I-beams may be connected to the web and lower flanges of the I-beam spaced below the slab to provide increased rigidity. The same structure is disclosed with channel beams. A wooden frame is disclosed wherein the frame beams are made up of two frame parts connected side-by-side with the outer frame part higher than the inner frame part and the slab received so as to be coplanar with the upper edge of the inner frame part, such upper edge being utilized to secure the reinforcement network. Transverse beams are located between the two longer sides which are the same height as the inner frame part so as to be received in the slab at the level of the reinforcement and beams in place is disclosed as well as a method for utilizing such jig apparatus.
A structural element which constitutes a panel for a box-shaped prefabricated section, said structural element comprising a slab of concrete-like cast material, beams composed of a material other than concrete, said slab having an upper side and a lower side, said beams connected at substantially only on one side of said slab so that they are spaced vertically apart from the other side of said slab and the upper surface of said slab is higher than the upper surface of said beams, structural columns which are connected to said beams and extend normally therefrom, said columns each being fastened to an upper side of a portion of at least one of said beams, the lower side of said portion having said slab connected thereto, said beams being provided with an extension on the upper side of each said portion adapted to receive said columns, each said extension having circumferential configuration, the periphery of each said column having a uniform cross-section such that its periphery at its end defines a further configuration matched for being received in a close close fit by the outer side of its corresponding said extension, the form of each extension and of the part of the corresponding said column receiving same being such that it determines the exact position of said column relative to said beam on which the corresponding said extension is provided.
A structural element which constitutes a panel for a floor for a box-shaped prefabricated section, said structural element comprising a slab of concrete-like cast material, beams composed of a material other than concrete, said slab having an upper flat surface and a lower surface, said beams being connected on one of their respective sides at a level between said upper surface and said lower surface to said slab with their other respective sides spaced outwardly from the adjacent edge of said slab, columns connected to said beams extending normally therefrom, said columns being fastened to an upper side portion of said beams, the lower side of said portion having said slab connected thereto, said beams provided with an extension on each said portion adapted to receive said columns, each said extension having a circumferential configuration the outer side of which is matched to receive the interior lower peripheral part of the corresponding column, said extension extending upwardly from the beam to which it is fastened to a level lower than the level of said upper surface, a recess in said slab in the area thereof adjacent each said extension and larger than the lower part of said corresponding columns received thereon, said recess receiving a hardening sealing material which substantially fills it to the same level as said upper surface.
A structural element which constitutes a panel for a floor of a box-shaped, prefabricated section, said structural element comprising:
A structural element which constitutes a panel for a floor for a box-shaped prefabricated section, said structural element comprising a slab of concrete-like material, said slab having an upper flat surface and a lower surface, beams formed of a structural material other than concrete, a portion of said beams being connected to the periphery of said slab at a level which is lower than said upper surface and higher than said lower surface, said portion of beams having locations on an upper side which are free of said slab, said portion of beams having structural columns extending normally from said locations to the top of the section, extensions mounted at said locations on said beams each having a circumferential configuration which snugly receives the lower peripheral part of the corresponding said columns, said portion of beams including two parallel longitudinal beams connected to said slab on opposite sides thereof and two parallel transverse beams arranged between said longitudinal beams, a further longitudinal beam between said two longitudinal beams and parallel thereto, all said longitudinal beams and said transverse beams having the same height, their upper sides being at a level between said upper surface and said lower surface.
A structural element which constitutes a panel for a floor to be incorporated in a box-shaped prefabricated section, said structural element comprising a rectangular slab composed of a cast concrete-like material, a peripheral rectangular frame of I-beams having its outside dimensions substantially the same as the outside dimensions of said slab, said I-beams all having substantially the same cross-section and being rigidly connected together whereby their upper and lower flanges fall within parallel planes, one side of the upper flange of said I-beams received substantially in the lower portion of said slab with the upper surface of said upper flange substantially covered by said slab which is in direct contact therewith, said slab having been cast with said upper flange side received affixed therein and said lower flange spaced apart from the bottom of said slab, a reinforcement network also cast within said slab attached to said upper flanges, a recess provided at each corner of said slab, an upright extension mounted on the top of said upper flange in each said recess, each said extension snugly receiving an upright column provided at each vertically disposed corner of the section, said frame of I-beams being rigidly and structurally interconnected under said slab across opposite sides by a plurality of further beams only, said further beams all being spaced entirely below said slab and having their lowest aspects contained in the plane of said I-beams.
