Definitions

  • ABSTRACT The metallic frame-work and floor resulting therefrom is composed of lengthwise extending frame members closed on at least part of their length by an added metallic strip, cross-pieces being secured'to lateral sides of said frame members and Z-shaped terminal flanges connected to outer sides thereof.
  • the present invention relates to a new frame-work for floors made of thin folded iron sheets and which, in case of need, makes possible the whole prefabrication at plant of a floor which eventually may include the ground coating and the ceiling coating and further inserted pipe for circulating fluids.
  • the floor although made of metal has high sound proofing properties.
  • the floor is such that it may be mounted only by laying on framing elements of a building, without the necessity of making use of securing means or of a layer of concrete orlike material.
  • a further advantage of the invention is that the floor may have a very long span between bearing points and thus makes possible the realization of very simple carrying structures and which participates to the resistance thereof.
  • the metallic frame work and floor resulting therefrom comprise lengthwise extending frame members constituted by steel sheets folded substantially in the shape of a trapezoid with the large base thereof directed downwardly and laterally extended by at least a wing, said frame members being closed on at least part of their length'by an added metallic strip constituting said large base, cross-pieces having in cross-section the shape of a trapezoid ex tended by a wing protruding from the large base thereof and the ends of which are diagonally cut-off and secured to the lateral sides of said frame members and at least Z-shaped terminal flanges connected to outer sides of said frame members and provided at the top'thereof with a bearing surface substantially aligned with the top of said floor.
  • FIG. 1 is a partial prospective view illustrating the frame-work of the box-shaped floor of the invention
  • FIG. 2 is a partial end section of the floor unit.
  • FIG. 3 is a cross section of the frame-work roughly made along line III-'III of FIG. 1.
  • FIG. 4 is a perspective view of the completed floor.
  • FIG. 5' is a perspective view showing a further application of the invention. 7
  • FIG. 6 is a partial perspective view showing the structure of the floor frame-work according to a modification.
  • FIG. 7 is a longitudinal sectional view of the floor shown along line VII-VII of FIG. 6.
  • FIG. 8 is a transverse sectional view along line VIII- -VIII of FIG. 6.
  • FIG. 9 is an exploded perspective view showing the floor being completed.
  • FIG. 10 is a schematic partial perspective view illustrating a further development of the invention.
  • FIG. 11 is a perspective view showing a detail of FIG. 10.
  • the floor frame-work is constituted of frame members 1, la, lb made of folded steel sheets, having in cross-section the shape of a trapezoid, the large base of which is extended by side wings 2 clearly shown on FIG. 3.
  • the frame members I which have their concavity downwardly directed are closed on their whole length or on a part thereof by means of iron plates 3, so that it is possible to regulate the moment of inertia of said frame members, of which the resistance to mechanical forces to which they are submitted may, thus be adjusted to have a very high value although the sheets used for the manufacturing of the frame members are very thin (for example about 1.5 mm).
  • the frame members are connected together from place to place by means of cross-pieces 4, made exactly like the frame members by folded trapezoid shaped iron sheets.
  • the ends of said cross-pieces are obliquely cut in order to bear on the sloped sides of the frame members 1, while wings 4a thereof bear on the wings 2 of two consecutive frame members as clearly shown on FIG. 3.
  • Connection between the cross-pieces 4 and the frame members is preferably made either by means of welding scams or, eventually, by electric welding between wings 2 and 4a.
  • the frame members and eventually the iron sheets 3 secured to said frame members engage the base plate 5 of terminal flanges 6, having towards the outside of the floor a protruding edge 7 extended by a raising edge 8 (FIG. 2) whereby the terminal flange 6 has substantially a Z-shape extended by the raising edge 8.
  • An angle iron 9 is connected to the flanges 6 in order to coverthe top of the frame members which are thus boxed-up in the terminal flanges 6 to which they are secured by any suitable means.
  • said framework when the frame-work of the floor is assembled, said framework have the shape of a frame delimited by the side flanges l0 and the terminal flanges 6, and that cells are delimited in the thickness of the frame, by frame members l and cross-pieces 4.
  • the above described frame-work is provided on its top with a wide-waved ribbed sheet 11 (FIGS. 2 and 4).
  • Lathes 13 made preferably of wood are disposed in the hollow ribs 12 of said ribbed sheet, these lathes extending across the direction of the frame members. In that manner, said ribbed sheet 11 shows a flat top surface since the lathes 13 are completely filling up the hollow ribs 12.
  • the ends of said ribbed sheets are fixed to the terminal flanges 6 and the sides thereof to the flanges 10. Moreover, the sheet may be connected by means of screws both to the members I and to the cross-pieces 4.
  • the lathes 13 are consequently used as filling material for the screwing of bolts, screws and the like.
  • the covering sheet 11 is evenly distributing the loads on the whole area of the floor-frame, particularly since the ribs thereof extend transversally to the direction of said frame members.
  • the protruding edge 7 of the terminal flanges 6 is used as a bearing surface for making the whole of the floor to bear upon the top of supporting girders, such as girders 14 shown on FIG. 2.
  • the width of the protruding edge is provided, for instance, to overlay only one half of the girder 14, so that two floors may be endto-end joined.
  • the above described floor when provided to be prefabricated in factory, includes advantageously the constitutive elements of a ceiling, said ceiling being made of slabs or wall-tiles 15, of square or rectangular shape, which are fixed under the frame members and under the cross-pieces, for example, by means of self tapering screws 16.
  • said ceiling is advantageously provided -with a removable cover 17 made of steel sheet or synthetic resin sheet said cover fitting on the floor flanges and thus covering entirely the ceiling.
  • said floor may also receive the ground coating and, in this case, as shown by FIGS. 2 and 4, it is provided to fix previously on the upper surface of the sheet 11, a sheet or plate 18 made of relatively flexible material such as a felt or a rubbery product or the same on which is laid the final ground coating, referred 19.
  • the covering sheet 11 delimits with the floor frame-work channels and recesses 20 either for the passage of pipes, or used directly for the circulation of a gaseous fluid such as ventilating air.
  • the frame-floor such as above described may particularly be easily adapted to a building with a very deep sound proofing, and this in spite of its all metallic structure.
  • the cells delimited between the frame members and the cross-pieces as well as the hollow bodies delimited by said frame members and crosspieces are, preferably, tilled-up with sound deadening material which is thus divided, this division improving the sound proofing qualities of the used materials.
  • the cells and hollow bodies are, preferably, filled-up with glass-wool compressed on a support, made for instance of bituminous kraft paper, thus making-up sound insulating panels which are stacked into said cells in such a manner that the supports are arranged in opposition with respect to the floor median plate 21 (FIG. 3). In this way, a reflective effect of the sound waves will be obtained simultaneously with a damping of said waves.
  • FIG. 5 illustrates a further development of the inve htion according to which the frame-work comprises at the ends thereof cross-pieces 4, one of these having wing 4a, flushing with the ends of the frame members.
  • intermediate wedges 2 similar to cross-pieces 4, but these wedges comprise on their top surface a plate 23 in order to make possible their fixing, for instance by screwing together on the wings and on the top of lateral frame members of two adjacent frame-work elements, as for example elements A and C on FIG. 5.
  • a continuous girder is obtained at the ends of the successive frame-works of the floor and it is thus possible to join two successive uprights 24 and 25 only by means of a folded sheet 26 of which the wing 26a closes the girder formed by the floor-frame.
  • Said wing which may bereinforced as shown at 27 fairly increases the bending moment of said girder.
  • the frame-work includes three frame members 1,, la, and lb, made of folded iron sheet.
  • the median frame member 1a is similar to those described above and has in cross-section the shape of a trapezoid of which the large base is extended by lateral wings 2. 1
  • Lateral frame members 1, and lb, (FIG. 7) have the shape of a right angled trapezoid and are provided with only one lateral wing 2,.
  • Frame members 1 have their base closed on the whole or on part of the length thereof by means of iron sheets 3 for the median member la, and by means of iron sheets 3, and 3, for the lateral right angled trapezoid shaped members.
  • Iron sheets 3, and 3 are folded at right angle in order to form a rising edge soldered within the volume delimited by said frame members 1, and 1b,.
  • Frame members are connected from place-to-place by cross-pieces but, as shown on FIGS. 6 8, the crossmembers are made of iron sheets 30, cutin the shape of an isocelestrapezoid and folded in an obtuse angle, in order to be applied on the sloped sides of the frame members while, by means of their wings 31, they bear on the top of said frame members, and by means of their wings 31a they bear on the frame member wings.
  • Frame members are, at their ends, placed on the base plate 5 (FIG. 6) of the Zrshaped terminal flanges 6 having, towards the outside of the floor a protruding edge 7 extended by a raising edge 8.
  • a wedge of absorbing or damping material as for example the material known under the same of neoprene is fixed under the edge 7, as'shown in 7a, in order that said wedge insulates the floor from the metallic or concrete supports 47 (FIG. 8) on which said floor bears by means of said edge 7.
  • FIG. 8 shows that supports 47 provide a clearing with the flanges 6, this avoiding sound transmissions and making possible the compensation of building tolerances frequently important in the building manufacturing.
  • An angle iron 9 is fixed upon each flange 6 in the purpose of covering the frame members top surface, so that said frame members are wholly surrounded by the terminal flange 6 to which they are connected by any suitable means.
  • the top surface of the above described frame-work is covered by plates 32, preferably made of compressed rock-wool, said plates being besides themselves covered with a panel 33 made of agglomerated material making possible the further fixing of any kind of desired ground coating.
  • the volume extending from the bottom of the plate (or plates) 32 up to the iron sheets 3, 3, and 3 closing the frame members is entirely filled with panels 34, 34a 34n arranged both between and inside the frame members, said panels being, for example made of rock-wool coated in a casing forming a spacer diaphragm between the various panels.
  • reflective screens are constituted spacing the absorbing coating forming the panel of rock-wool or similar material thereby preventing propagation of sounds in a very unexpected manner, owing to the slight mass of the floor with respect to a conventional floor composed of heavy elements, for instance made of concrete, and spaced by light elements made of felt or synthetic resin.
  • Sheets 3, 3,, 3, are used for fixing, under their bottom surface, strips 35 also preferably made of agglomerated rock-wool, said strips being, for example fixed by gluing by means of a glue made of synthetic resin.
  • Strips 35 are provided within their thickness, are particularly shown on FIG. 7, with magnetic parts 36 made for example of soft iron which are embedded within the thickness of the material of which said strips are made.
  • the strips 35 make that, between the ceiling and the insulating panels 34 34n, free spaces 39 are delimited FIG. 7) in which it is possible to lay out various pipes and eventually to set some fluids circulation.
  • rectangular floor panels with a thickness of 12 to 20 cm and having a length possibly reaching about 6 meters and a width 2.5 meters while using for the manufacture of such frame-works thin iron sheets of about 1.5 mm in thickness.
  • a further object of the invention is to make possible theautomatic assembling of two adjacent floor-panels and, for this purpose, as shown on FIGS. 10 and 1 l, the frame members lateral edges 3 are fitted with strap shaped gussets 40, each of said gussets having a small bar 41 (FIG. 11) fixed thereinto.
  • frame members 3 are provided with lugs 42 forming a tongue 43 bounded by a folded edge 44.
  • gussets 40 and 42 are at least for a part sunk into plates made of absorbing material made of agglomerated rock-wool; said plates being arranged on the lateral sides of frame members 3 and 3 as shown under reference number 45 on FIG. 2.
