Definitions

  • This invention relates to structural members, and is more particularly, but not exclusively, concerned with structural members of galvanised steel frames for buildings.
  • U.K. Specification No. 2,146,054A describes a steel frame for this purpose which incorporates a channel-section bottom member having two ribs formed in the bottom of the channel and extending parallel to the sides of the channel. These ribs serve to support upright members having their ends extending into the channel in such a manner that there is a gap between the end of the upright member and the bottom of the channel which allows moisture accumulating within the channel to drain freely along the length of the channel.
  • an elongate structural member of channel section having a central web and two parallel flanges extending along opposite edges of the web and projecting to one side of the web, at least one rib being provided in the central web and projecting into the channel formed by the member, wherein at least one drainage hole is provided in the member so as to enable drainage of moisture accumulating within the channel at a point intermediate the two ends of the member.
  • Such an arrangement provides a significant improvement in terms of resistance to corrosion over the long term since it enables moisture to drain off not only from the ends of the member, but also from one or more points intermediate the two ends.
  • drainage holes are provided at equally spaced locations along the length of the member.
  • the drainage holes may be provided in at least one of the flanges. If provided in both flanges, the holes may alternate between the two flanges along the length of the member. Furthermore each hole may be formed so as to extend both through a flange and through the adjacent portion of the central web.
  • each rib extends longitudinally of the member, and at least one discontinuity is formed in the rib(s) at a point intermediate the two ends of the member so as to enable drainage of moisture at this point between the portions of the web on opposite sides of the discontinuity.
  • the discontinuity preferably comprises simply a portion of the web which is flush with the portions of the web on the two sides of the discontinuity.
  • discontinuities are provided in the or each rib at equally spaced locations along the length of the member. If two ribs are provided in the central web extending longitudinally of the member, the discontinuities in the two ribs may be staggered in relation to one another along the length of the member.
  • the invention also provides a method of forming such a structural member utilising separate rolling and punching operations, and preferably also a pressing operation.
  • the invention also provides a method of forming such a structural member comprising a casting operation.
  • the channel-section structural member 1 comprises a central web 2 having parallel ribs 4 and 6 extending along its length and two parallel flanges 8 and 10 extending along opposite edges of the web 2 and projecting in the same direction as the ribs 4 and 6.
  • Drainage holes 12 are formed in the flange 10 at 300mm spaced centres along the length of the member 1. These holes 12 overlap the bottom of the flange 10 and extend into the edge of the web 2. No drainage holes are provided in the flange 8.
  • discontinuities 14 are provided in the rib 4 at 300mm spaced centres along the length of the member 1
  • discontinuities 16 are provided in the rib 6 at 300mm spaced centres along the length of the member 1.
  • the discontinuities 16 in the rib 6 correspond in position to the drainage holes 12 along the length of the member 1, whereas the discontinuities 14 in the rib 4 are staggered in relation to the discontinuities 16 in the rib 6,being offset by 150mm longitudinally in relation to the discontinuities 16 and the drainage holes 12.
  • the drainage holes 12 and the discontinuities 14 and 16 in combination enable free drainage of moisture accumulating in the channel at points intermediate the two ends of the member 1, in addition to the drainage at the two ends of the channel.
  • the above-described structural member is intended primarily for use as the bottom plate of a frame, although it may also be used for studs, noggins, top plates and bracing plates of wall panels, as well as for struts, ties and bracing plates of roof trusses. Generally the member will have longer flanges when used for the bottom chord of a roof truss.
  • the member 1 may be formed by two possible methods, namely by a pressing method and by a roll-­forming method.
  • a blank in the form of a flat sheet of a predetermined fixed length and an overall width of 150 mm, for example, is placed in a press brake machine with a maximum tool length of 3658 mm, for example, and the two ribs are pressed in separate operations.
  • hole punching to a predetermined pattern is carried out.
  • Two right-­angled holes are then produced to form the required channel section, and finally the section formed is passed through another tool which produces the flattened discontinuities at predetermined centres one rib at a time.
  • a narrow coil of galvanised steel (for example about 140 mm in width) is fed through a roll former which performs the various operations to produce the final section. If required hole punching can be performed prior to use of the roll former.
  • the ribs may be formed either continuously followed by a further operation to form the flattened discontinuities in the ribs, or intermittently with the discontinuities being left between adjacent rib portions.
  • the section is then passed through a series of stages which gradually form the sides of the channel. Finally the fully formed section is cut to a predetermined length.
  • a protective coating is preferably applied to the member after forming, either by brushing or by spray application.
  • the coating is preferably a cold applied bitumen heavy duty coating which is applied in the form of a thixotropic paint.
