Definitions

  • the invention relates to a structural member formed of sheet metal for use in construction of buildings, and in particular to a metal stud member for use in building of bearing and non-loadbearing walls and partitions.
  • Construction makes use of studs either of wood or metal.
  • Metal studs are greatly preferred in many forms of construction, since they are resistant to termites, rot and fire damage.
  • Metal studs are lighter than wooden studs, of equal strength, and are thus suitable for non-loadbearing walls and partitions in commercial buildings. In high rise buildings they are preferred, or even required by architects and engineers, in order to avoid excessive weight in the building.
  • Metal studs support wall covering materials and are frequently used in association with panels of drywall material. Walls also carry services such as wiring, and the like.
  • any metal stud it is desirable to reduce the effects inherent in the use of metal, such as transfer of heat, and transfer of sound. Heat loss is a significant problem in exterior walls.
  • Various proposals have been made to provide studs for exterior walls, in which the path for heat transfer has been reduced by forming openings in the stud.
  • the studs should be as free as possible from sound transfer. It is also desirable that they shall be as rigid as is required to maintain the panels in position, and also to be as light as possible.
  • typical metal drywall studs involved a generally three sided channel section having a central web and two side walls, bent into a channel shaped cross-section. This section was continuous along the length of the studs.
  • the invention comprises a light weight structural metal stud member, formed of thin gauge sheet metal, and having two parallel spaced apart generally L-shaped angled members extending parallel to one another, a plurality of spaced apart strut members extending integrally from one said angle member to the other, and defining openings therebetween, edge flange formations formed on the said strut members, enlarged root portions on each end of said strut members where the same join said L-shaped members, each of said L-shaped members defining parallel spaced apart panel attaching facing flanges, lying in generally parallel spaced apart planes, to which wall covering materials may be attached, and, a plurality of intended rib formations formed transversely of said L-shaped angle portions, said ribs being formed in said wall facing flanges, and in adjacent portions of said L-shaped angle members, said ribs being formed at spaced apart intervals along the length of said L-shaped members, whereby to resist flexing of said facing flanges during
  • a typical wall comprises panels of walls covering material, typically plasterboard or dry wall materials, indicated as panels 10, supported on spaced-apart vertical metal stud members indicated generally as 12.
  • the stud members 12 in this embodiment will typically be spaced apart at intervals of sixteen inches, assuming that the panel 10 has a standard dimension of four feet by eight feet. In some wall systems the studs may be further apart or closer together, and in any event this is well known in the art and forms no part of the invention.
  • top and bottom plate members (not shown) which will typically be metal channel sections attached to the floor and to the fabric of the ceiling, for securing the top and bottom of each stud.
  • Figure 1 illustrates wall panelling materials on both sides of the stud, and thus illustrates an interior wall
  • wall panelling would be attached usually to only one side, and some other material would be attached to the other side, depending upon the type of construction.
  • the panels 10 are secured to the studs 12 by means of fastening devices typically being so-called drywall screws shown generally as 14.
  • Such screws 14 while forming no part of this invention, are of significance in that they are generally formed with what is known as a self-tapping point. In a typical drywall screw a portion of such point is cut away so as to leave a sharp cutting edge.
  • the drywall stud according to the invention will be seen to comprise inner and outer generally L-shaped angle portions 20 and 22.
  • Both angle portions 20 and 22 are of identical construction. They comprise facing flanges 24, 26 and side flanges 28, 30 normal thereto. The free edge of the facing flanges 24 and 26 are turned in as at 32, 34.
  • the outwardly directed surface of the facing flanges 24, 26 may be provided with a surface formation defining a plurality of small closely spaced indentations. These indentations are now shown, but in any event it is well understood that they facilitate the insertion of the screwpoint into the sheet metal, by their tendency to hold the screw point and prevent it from slipping sideways on the metal surface.
  • struts 36 Extending between the two angle portions 20 and 22, are a plurality of generally diagonally arranged struts 36.
  • Each of struts 36 comprises a web portion 38 and sidewall portions 40-40.
  • the free inward edges of the side flanges 28 and 30 are turned inwardly as at 42, 44.
  • the inturned portions 42-44 are continuous edge-wise extensions of the sidewalls 40-40 of the struts 36.
  • openings 46 of generally trapezoidal shape.
  • the roots or ends of the struts 36 are flared outwardly, as at 48,50, and thus provide a smooth transfer of forces from the angle portion 20-22, through the struts 36.
  • a plurality of transverse indented rib formation 52-54 are formed.
  • the rib formations 52-54 extend in this preferred embodiment preferably in the region of the flared portion 48-50 at the end or roots of the struts 36.
  • Additional such ribbed formations are formed at periodic intervals along the length of the angle members 20-22.
  • ribs 56-58 are formed extending into the roots of the struts and preferably merging with ribs 52-54.
  • Ribs 56-58 will be formed at one stage of the manufacture. Ribs 52-54 will be formed later, after formation of the longitudinal bends in an angle portions 20-22.
  • the wall panel covering materials are applied and fastened by means of screws.
  • the point of the screw will pierce the facing flange, and then pass through it, and the threads of the screw will then form their own thread, thereby causing the screw to become fastened in the facing flange.
  • the side flanges 28 and 30 provide a convenient means for attaching electrical service boxes for example again by means of sheet metal screws or drywall screws.
  • any tendency for the struts 12 to flex is substantially reduced by the angled formations 20 and 22, being connected by means of transverse struts 36, which comprise channel sections along their length, and having sidewalls 30 merging with inturned edge portions 42, 44 of the angled portions 20 and 22.
  • the improved rigidity inherent in a stud according to the invention enables studs to be made of thinner gauge sheet metal. This produces a saving in weight, and also a saving in material cost, without an unacceptable loss of rigidity.
  • FIG. 3 and 4 A further embodiment of the invention is shown in Figure 3 and 4. It will be seen that this embodiment comprises inner and outer column portions 60 and 62, each of which comprises a facing flange 64, adapted to lie in the plane of the wall and adapted to support wall covering materials. At right angles to the facing flange 64, is a side flange 66. At right angles to flange 66 is a return flange 68. The free edge of facing flange 64 is turned inwardly at right angles as at 70.
  • the free edge of return flange 68 is turned inwardly at right angles, as at 72, so that it lies in the same plane as side flange 66, and is located in a plane spaced more or less between the plane of flange 66, and edge 70.
  • Struts 74 are of generally channel shaped cross section having an enlarged root portion 76, and side walls 78 formed at right angles thereto.
  • openings are formed of generally triangular shape.
  • Flanges or walls 78 continue completely around such openings, and extend along side the free edges of flanges 72, thereby providing a continuous right angular reinforcing rib or flange giving extra strength.
  • right angular transverse indentations for ribs 80 are formed at spaced intervals, extending through the right angular corner between flanges 64 and 66.
  • Additional strength can be provided by forming similar further reinforcing ribs 82, across the right angular joint between flanges 66 and 68.
  • the adjacent ends of the ribs 80 and 82 should overlap and register with one another so as to form continuous ribs through flanges 66.
  • ribs 86 may also be provided at the roots of struts 76, extending through the flanges 72 and into the flanges 68.
  • right angular L-shaped portions 90 and 92 are formed, having panel supporting facing flanges 94, and side flanges 96, formed at right angles to one another.
  • Edge flanges 98 are turned in on the free edge of flanges 94.
  • Members 90 and 92 are formed integrally of a single piece of sheet metal, and are connected integrally by interconnecting struts 100.
  • Struts 100 are separated from one another by means of openings 102 which in this case are formed as circular openings. Rims or edge flanges 104 are turned inwardly all around openings 102 for greater strength.
  • transverse reinforcing ribs 106 are formed, extending right through struts 100 and preferably into side flanges 96.
  • transverse indented rib formations 108 are formed in the same way as in the embodiment of Figure 2, at spaced intervals there along, whereby to resist flexing of the flanges 94.
