Description

    Technical Field of the Invention
  • This invention relates to the cladding of structural steel members especially for fire protection purposes. In particular, it relates to a method of attaching cladding boards to I or T section steel joists, herein referred to as flanged structural steelwork.
    • The Prior Art
  • Hitherto, boards have been and for that matter, still are attached to such steelwork by methods involving the use of battens and/or blocks of material jammed or otherwise secured to the steelwork between or extending along the flanges. The boards are thereafter screwed or nailed to these battens/blocks, sometimes with the aid of adhesive compositions to fill any gaps. The object of these fixing methods is to substantially completely enclose the flanged structural steelwork without actually drilling into it, if at all possible. In general terms, the use of such methods is labour-intensive and frequently necessitates the carrying out of complicated assembly work in relatively inaccessible locations, often with the aid of ladders and/or scaffolding.
  • CH-A-378514 discloses a method of attaching flat cladding panels to walls and/or ceilings. The method involves the use of U-shaped metal channels into which timber battens can be fitted.
  • These battens may be secured either to the wall/ceiling or to the cladding. However, this method is essentially intended for use with flat surfaces. It takes no account of the problems of flanged structural steelwork and more important, it is not concerned with protecting such steelwork from fire. Also it relies on purely frictional forces to retain the timber batten in place in the channels. It is therefore extremely vulnerable to fire.
  • It is an object of the present invention to simplify the installation of fire protection cladding, by the use of plain boards, readily-available metalwork and no internal or external preformed clips, whilst at the same time achieving an improved degree of structural integrity in a fire.
    • Description of the Invention
  • The invention resides in the use of single U-shaped metal channel members to attach cladding boards to flanged structural steelwork (as herein defined).
  • According to one aspect of the invention, a method of attaching cladding boards to flanged structural steelwork (as herein defined) so as to substantially enclose the latter, comprises the steps of fastening the respective bases of single U-shaped metal channel members to each one of a pair of boards so that the arms of the U project substantially normally of the board, presenting the boards to the steelwork so that an oppositely directed flange thereof is received in each of said channel members, presenting a third board to the other two so as to completely bridge and fill the gap between them and lie against an arm of each channel followed by fastening said third board to each of said arms.
  • It will be appreciated that the foregoing method serves to clad flanged structural steelwork on three sides, but the principle applies equally to the fourth side of an I-section joist the method then including the steps of fastening U-shaped channels to each of the first two boards and presenting and fastening a fourth board, in the same manner as the third board, above.
  • However, according to another aspect of the invention, a method for attaching cladding boards to flanged structural steelwork comprises joining two boards at right angles by fastening them to one arm and the base respectively of a single U-shaped metal channel member to form an L-shaped assembly and fastening a second single U-shaped metal channel member to one of said boards so that the arms of the U extend from the board parallel to those of the first channel member in the assembly; a second such assembly is then formed and the two assemblies are presented to opposite sides of an I-section flanged structural steelwork joist so that the parallel flanges thereof are received in the respective parallel channels with an arm of each assembly abutted against one of the respective side walls of each of the second channel members, followed by fastening said arms to said side walls to substantially enclose the I-section joist.
  • A particularly preferred fastening method is by the use of self-tapping screws, especially of the kind which drill their own pilot hole in the metal channel member. This enables the installation of cladding boards to be carried out without any conventional drilling operations and this helps to speed assembly.
  • An important advantage of the invention resides in the fact that fastening does not rely on any screwing or nailing only to the material of the boards themselves; the metal channel supports the load. Furthermore, it is not necessary to drill the flanged structural steelwork. Also, as much work can be carried out at ground level, installation reduces to cutting and partial assembly (on the ground), followed by temporary clamping to the flanged member and a final fastening operation.
    • Description of One Embodiment of the Invention
  • One preferred embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which the sole figure is a cross-sectional end view of an I-section joist supporting a floor slab.
  • In the figure, a concrete floor slab 1 rests on the upper face 2 of an I-section joist, 3. Fire protection boards 4, 5 and 6 enclose the joist on its three exposed sides, being retained in place by self-tapping screws (of the self-drilling kind) 7, which fasten the boards to light steel channel members 8 and 9 respectively. The gap 10 between the slab and the edges of the boards abutting the slab is filled with a conventional cement/adhesive composition, 15.
  • Installation of the cladding was carried out by the first of the two basic methods described earlier. The boards 4 and 5 were fastened to the bases of their respective channel members 8 and 9. These boards were then temporarily clamped in place on the joist after trowelling on the cement/adhesive 15, wedges being employed to preserve the gap 10 and hold the arms 11, 12 of the channels against the inside faces 13, 14 of the lower flanges of the joist. This was necessary to prevent extrusion of the cement/adhesive on carrying out the next step, which was the installation and fastening in place of the remaining board 6, to cover the lower face of the joist.
