Definitions

  • ABSTRACT A load-supporting construction element, for spanning a pair of spaced-apart supports and adapted to form a wall, floor, deck or roofing structure or a support for a wall, floor, deck or roofing surface which consists of a sheet-metal plate of generally rectangular-plan configuration and a plurality of troughs and crests in alternating relationship and of trapezoidal cross-section.
  • the apices of the troughs and/or crests are provided with integral (unitary) ridges concave in the direction in which the corrugation bulges and of trapezoidal or arcuate cross-section.
  • the flanks of the trapezoidal corrugations are stepped.
  • the present invention relates to a construction element and, more particularly, to a load-supporting, support-spanning, structural member of rectangular-plan configuration and adapted to be used as wall, floor, deck or roof member and/or as a sheathing for any structure and/or as a partition member, alone or in combination with a planar or other supported surface.
  • flooring built up from wood, slabs, cast in situ or prefabricated of concrete, or boads, plates or sheets of a variety of materials adapted to rest upon the supporting members and designed to span large areas.
  • structural elements having a generally flat configuration and intended to span large areas were integrally or unitarily provided .with stiffening formations intended to to increase the load-supporting capacity of the body and to replace girders, beams and separate supports which otherwise were required to extend along the flat web of the structural element.
  • Typical of systems of the latter type were concrete slabs cast with trapezoidal ribs to form a monolithic body in which the ribs served as beams and the web'between the ribs as the covering portion of the structural element.
  • Another object of the invention is to provide a generally flat or sheet-like structural element which may be used as a load-supporting member without girders, beams or the like, i.e. which provides the compression and tension flanges upon loading in an integral or unitary manner.
  • Still another object of the invention is to provide a generally flat, load-supporting construction element with increased load-bearing capacity without increases in thickness of the material and with satisfactory stacking ability.
  • the stiffening ribs of generally trapezoidal cross-section comprise flanks or side walls which converge alternately upwardly and downwardly to a crest or trough which, according to the present invention, is provided with a longitudinally extending unitarily formed profile rib which is concave in the direction in which the corrugation bulges and which has a transversewidth equal to at least a substantial fraction of the width of' the flattened crest or trough in which it is formed.
  • the structural element which can be used as a roofing plate, a wall plate, a sheath plate or the like, or for any of the other purposes previously described, also is provided along the flanks of the trapezoidal cross-section with longitudinally extending steps such that a transition is formed between a slender trapezoid in the region of the small side of the trapezoidal corrugation and an enlarged trapezoid close to the broad base thereof.
  • This combination of a step in each flank and a rib or channel in each crest or trough has been found to impart substantially greater stiffness and antibuckling resistance to the construction element than has been attainable with existing corrugated plates and furthermore permits the plate to take up shear stresses and bending moments in the transverse direction with greater effectiveness.
  • the width of the flattened crest or trough is substantially equal to the height of the flanks or walls of the corrugation and the altitude thereof.
  • the alternating corrugations of the plate constitute the compression and tension flanges of the structural element when the latter is a load-supporting body in accordance with the present invention and the crest ribs and flank steps have been found to enable the altitude of the corrugations to be relatively high.
  • the compression and tension flanges can effectively be removed from a median plane through the plate to a much greater extent than has been possible heretofore.
  • the stacking properties of the plate are thereby improved as is the load-carrying capability for a given sheet thickness.
  • the crest rib is formed of arcuate cross-section along the upper portions of the plate and of trapezoidal crosssection along the downwardly facing portion of the plate, in both cases the crest rib being dimensioned to correspond to at least 90 of circular arc.
  • the side walls preferably include angles of about 1 with horizontal flanges of the plate while the angle of the step is advantageously about 145.
  • FIG. 1 is a perspective view of a structural element according to the present invention.
  • FIG. 2 is a detailed view of a portion thereof in end elevation corresponding to the region viewed along line 11-11ofFlG. 1.
  • the generally fiat structural element illustrated in the drawing is preferably round from sheet metal or extruded from a synthetic resin using a round extruder and in most cases will be composed of a sheet metal such as aluminum or steel which may be coated with anticorrosion layers or the like.
  • the plate is of rectangular plan-configuration and is formed with corrugations 1, 2, 3, extending in the longitudinal direction and alternately open upwardly and downwardly. Each corrugation is defined between a pair of flanks or side walls which converge upwardly to a flat tened crest 2 or downwardly to a flattened trough 3.
  • the plate is generally employed as a roof, wall or sheath member.
  • the side walls or flanks 1 are provided with longitudinally extending steps 4 inclined in an angle of substantially 145 to the wall or flank which, in turn, includes an angle of 115 to the horizontal portions 2 and 3 extending therefrom.
  • the steps 4 are located approximately midway of the height of each wall or flank 1.
  • the crests 2 of the upwardly bulging corrugations are formed with reinforcing ribs 5 of arcuate cross-section, the ribs 5 defining a concavity open in the direction in which its corrugation bulges.
  • ribs 6 are formed in the trough floor 3 and open in the direction in which their corrugations bulge, i.e. downwardly.
  • the formations 5 and 6 extend in cross-section over substantially a quadrant of a circle, i.e. about 90, as shown at e in FIG. 2.
  • the altitude G of rib 6 is approximately 125 mm in the preferred case and has abroad base E substantially twice as wide as its narrow base L. E may be about 3 G.
  • the thickness of the plate is preferably about 1 mm. Structural elements of this type have been found to be satisfactory for spanning large distances and carrying considerable loads.
  • the transverse width A or D of the flattened crest 2 or trough 3 of the respective corrugation is approximately equal to the altitude H thereof.
  • the width of the channel formed by the rib 5 or 6 is represented at B or E, respectively, and A/2 s B E s A/4 and preferably B E z A/3.
  • the altitude F z G of the formations 5 and 6 may be defined by the relationship 13/4 PS B/2 so that in the preferred state F z 8/3.
  • the step ofeach flank 1 may have a width 1 z I-1/4 or K/2 wherein J and K are respectively with widths of the portions of the side walls flanking the step 4.
  • the angle a between the flank K and the floor 3 ofa trough is about 1 15 as previously described while the angle B between the portions of the side wall 1 and the step 4 formed therein may be 145.
  • the angle y between the side wall and crest 2 is approximately 1 15 while the angle 8 of the flank of the rib 6 is about We claim:
  • a construction element which comprises a generally planar plate of rectangular plan configuration unitarily formed with alternately upwardly and downwardly bulging corrugation of generally trapezoidal cross-section, said corrugations being formed with generally flat flanks converging to flattened crests and troughs respectively, said flanks being formed with lon gitudinally extending steps and said crests and troughs being formed unitarily with longitudinally extending rib profiles deformed therein and concave in the direction in which the respective corrugation bulges, said corrugations having altitudes approximately equal to the transverse widths of said flattened troughs and crests, said steps being formed substantially midway along said flanks, and said flanks including angles of about 115 with said flattened troughs and crestd and said steps include angles of substantially with said flanks.
