Definitions

  • the present invention relates to fastener arrangements, particularly to fire-resistant fastener arrangements, for securing plasterboard panels to a background construction material
  • Cavity walls can be insulated by full or partial filling of the cavity with an insulating material, whilst solid wall structures can have insulation fixed on the inner or outer wall surface.
  • Insulation can be supplied in laminated board comprising a layer of insulation fixed to a sheet of gypsum drywall to form a fire resistant insulated plasterboard panel. These panels are conventionally fixed to masonry wall surfaces via a dot and dab adhesive.
  • each insulated plasterboard panel has a tendency to fail in the event of elevated temperatures such as they may be subjected to in the event of a fire.
  • adhesives have a tendency to fail in the event of elevated temperatures such as they may be subjected to in the event of a fire.
  • each insulated plasterboard panel to be mechanically fastened to the background masonry.
  • the mechanical fastener arrangements can be used in place of the dot and dab adhesive or can be supplementary to it.
  • conventional insulated plasterboard fastener arrangements comprise a combination of a plastic wall plug with expanding tip and a masonry nail.
  • a clearance bore is formed through a gypsum layer, the insulation layer and into the masonry with a drill bit that is slightly larger than the plastic wall plug/ nail arrangement.
  • the plug is hammered into the bore and the nail into the plastic plug to expand the tip of the plug and a thin coat of filler is used to disguise the nail head location.
  • the filler bonds poorly with the nail head. It is not uncommon for the filler to fall from the nail head, leaving the head exposed.
  • plastics fastening arrangements tend to fail when subjected to elevated temperatures such as they may be subjected to in the event of a fire. It is also well known that masonry nails conventionally have circular (non-profiled) shanks, which do little to mitigate heat loss, and planar heads, which have little means of retaining filler material. Plasterboard panels include outer paper layers. A further problem with using conventional nails for attaching an insulated plasterboard panel to a background material in the situation where a pilot hole is not used, is that the head tears the nearside outer layer of paper.
  • the invention seeks to provide a fastener arrangement that mitigates at least one of the above-mentioned problems, or at least provide an alternative arrangement to known fastener arrangements.
  • the invention also seeks to provide a method for attaching plaster board panels to a background material.
  • a fastener arrangement for securing plasterboard panels, and particularly insulated plasterboard panels, which include an additional layer of insulation material, to a background material
  • the fastener arrangement comprising: a fastener having an elongate shank and a profiled head, wherein the profiled head includes a shallow dished surface.
  • Fastener arrangements in accordance with an embodiment of the present invention can be used to secure plasterboard panels to a background material.
  • the fastener can be driven through the laminated insulation boards into engagement with a background construction material, for example into engagement with wood, brick, block, concrete or stone using a complementary drive tool.
  • the profiled head portion can engage and indent into the top surface of the plasterboard to secure the board to the background material.
  • the shallow dish-shaped surface improves the ability of the filler material to bond with the fastener. This can help reduce the likelihood of the head becoming exposed and therefore reduces the effects of cold bridging. It also improves the overall aesthetic effect since fewer fastener heads are exposed.
  • the fastener arrangement is fire resistant.
  • the fastener can be arranged to withstand a predetermined temperature for a predetermined period of time without failing.
  • the fasteners is arranged to withstand temperatures in excess of 900°C for a rated period of time, such as 30 minutes. This can be achieved by making the fastener out of a material that melts at a temperature in excess of 900°C, for example a suitable metal such as steel.
  • the profiled head includes a substantially convex surface.
  • substantially convex surface is defined by the dished portion of the profiled head.
  • substantially convex surface and the dished portion meet at a raised rim.
  • the substantially convex surface is adapted to have a central planar portion arranged to receive the end of an elongate shank. This improves the manufacturability of the fastener since it is easier to locate the head onto the shank during manufacture.
  • the central planar portion has a diameter that is less than twice that of the circumscribed diameter of the shank.
  • the central planar portion has a diameter that is complementary to the circumscribed diameter of the shank.
  • the convex surface is fixed adjacent the elongate shank.
  • the substantially convex surface is fixed to one end of the elongate shank.
  • the shank is orientated such that it is substantially perpendicular to the substantially convex surface. This arrangement reduces the likelihood of the head tearing the outer paper layer of the plasterboard panel when the fastener is driven in.
  • the head is welded to the profiled shank. More preferably the central planar portion of the head is welded to the profiled shank.
  • the depth of the shallow dished portion is less than one and a half times the diameter of the elongate shank this ensures that the head can be engaged with and indented into the outer layer of the laminated insulation board, without the need for the head to extend beyond said outer layer.

  • the helical formation reduces heat loss by conduction, as well as reducing heat transfer by conduction during a fire, since it has improved grip with respect to a conventional nail while at the same time having a relatively modest core size in relation to its circumscribed diameter (A).
  • the elongate shank is profiled such as to form a cross-sectional area that is between 26% and 18% of its circumscribed cross-sectional area.
  • Figure 2 shows a magnified view of the fastener arrangement of fig 1. It can be seen in this figure how the shallow dished profile (1) forms a non-destructive smooth dished like indent with the plasterboard (4) so as not to tear the paper (5) as shown later in figure 3, the depth of the dish in this case is less than the profiled diameter of the helical shank (3). Preferably the depth of the dish is less than one and a half times the diameter of the elongate shank.
  • Figure 3 shows the effect of conventional heads (6) when driven into plasterboard (4) whereupon the plasterboard (4) paper (5) will shear through (7), with these types of head profile (6) there is no complementary curvature upon the paper (5) as shown in fig 2.
  • Figure 4 shows an alternative fastener arrangement where the head profile is domed to form of a cap (8) to receive misaligned axial impacts (13).
  • Such an impact profile (8) ensures that misaligned impacts (13) are re-directed into an axial path (9), such driving will otherwise cause the driven shanks (11) later shown in fig 5 to buckle.
  • Spherical driving via convex/concave surface upon the head (8) or tool (2) (such as in fig 2) re-direct impact forces (13), such that a component of force acts axially along shank of the fastener.
  • the driving tool is arranged such that it can be misaligned by up to 15 degrees, and the fastener can still be successfully driven into a plasterboard panel.
  • This coupling/ driving arrangement has specific merit when driven upon helical shanks (3) as the impacted forces (13) are free to follow the twisting urge, thus misaligned forces are re-directed longitudinally upon corrected axially centred helical path (9) as shown in figs 6 and 7.
  • Figure 5 shows how a misaligned impact force (13) upon a conventional head (10) will cause the shank (11) of a conventional driven nail to buckle and bend. This tendency would obviously be heightened if the shank profile was twisted into a helical profile (3)
  • Figure 6 shows how the fastener arrangement when using a profiled shank in the form of a helix (3) has a natural tendency to rotate when axially driven, the tool (2) which will have a complementary concave to convex profile freely allowing the rotational urge of the helical shaft (3), thus there is an additional complementary effect of the rotary impact when driven by a hammer drill (12).
  • the coupling interface of the spherical arrangement dramatically reduces the tendency for buckling and bending of shafts (11) in fig 5 especially when in helical form.
  • Figure 7 shows how such an arrangement of driving as elaborated in figures 4, 5 and 6 could be put into practice, where upon a rotary hammer drill (12) is being used to drive a helical fastener (3) close to the confines of a corner of a wall. In this case due to such confines it is imperative that a convex/concave coupler driving arrangement is used as helically profiles are likely to buckle and be difficult to straighten up in such circumstances.
  • An SDS type chuck can be used to grip the driving tool (2).
  • an air powered percussion apparatus can be used, such as pneumatic hammer device.
  • Figure 8 shows a fastener arrangement with a dished head (1) and a profiled shaft with a number of longitudinal tapered fins (15), such a profile again demonstrates the relative small cross-sectional area of the elongate shank in relation to its effective circumscribed diameter.
  • This sort of relationship similar to a helical shaft (3) is very effective in reducing conductive heat loss as well as reducing heat transfer the other way in a fire situation.
  • Figure 9 shows a fastener arrangement that includes a spreader plate (18) which engages upon a number of board surfaces at the corners, in this case located by tabs (17) which seat into the abutting edges (19) the fastener and spreader plate are engaged upon a spherical mating surface with the head (1) .
