Definitions

  • the present invention relates to flashings for finishing work in building construction.
  • Building flashings for use in construction work generally serve to bridge wall and/or roof surfaces in a building construction to assist the surfaces weather-tightness and to this end comprise an elongate member which includes a plurality of appropriately disposed wall portion which are set at an angle or angles to each other. Aluminium and commercial quality steel are suitable materials for the manufacture of flashings and can be subsequently coated with paint and/or zinc systems.
  • a building flashing made of metal, at least one wall portion of the flashing being structurally embossed.
  • the wall portions of the flashing are preferably of commercial quality steel or aluminium and may be coated with zinc and subsequent paint systems.
  • the embossing could create an array of separate individual deformations on the flashing wall portion or alternatively a series of elongate continuous deformations or corrugations could be provided extending parallel to a deformation axis.
  • an axis of the array or said deformation axis is set at an angle to the longitudinal extent of the flashing wall portion.
  • the deformation axis of the corrugations can be set transversely to the longitudinal direction of the flashing wall portion.
  • the individual deformations of the array pattern can have a variety of shapes in plan view. Thus these deformations could be of rectangular, circular, square or oblong shape in plan with other shapes possible. Further, deformations of different planar shape could be present in a particular array.
  • the structural embossment of the flashing wall improves the structural strength property of the wall and hence of the complete flashing, enabling a thinner wall to be used with a consequent saving in material and hence in cost, or alternatively, for a given wall thickness, increased structural strength is imparted to the flashing.
  • FIG. 1 shows various forms of building flashing 1, each of these flashings comprising an elongate member providing a number of appropriately disposed wall portions 2 a , 2 b , etc.
  • the flashing 1 of Fig. 1 is a flanged ridge flashing extending between roof parts 3, 4 at a roof ridge, while Fig. 2 shows a drip flashing located at the bottom of a wall 5.
  • the corner flashings 1 of Figs. 3A and 3B bridge wall portions 6, 7 at a building corner with the flashings 1 located externally and internally respectively by means of clamp plates 8.
  • the bargeboard flashing 1 of Fig. 4 is mounted at the top of a wall 9 i.e.
  • Fig. 5 shows a further type of flashing 1 in the form of a lipped barge­board.
  • the flashings 1 can be made of aluminium or galvanised commercial quality steel. Such commercial (or profiling) quality steel would be satisfied by designations Z1 and Z2 of British Standards 2989 i.e. defined as low grade commercial or profiling quality steel.
  • structural embossing E is applied to one or more of the flashing walls 2.
  • This em­bossing has the function of strengthening the wall and also strain harde­ning the wall material.
  • the embossing may be applied substantially over the full area of the wall, but it would be possible for the embossing to be applied at only selected areas of the wall.
  • the actual embossment pattern can be chosen from a wide variety of different forms, and Figs. 6 and 8 merely show two examples.
  • the embossment applies an array of separate individual deforma­tions 11, 12.
  • the deformations 11 are of oblong form in plan view while the deformations 12 are of a smaller circular shape, the pattern arrangement being defined by an orthogonal series of lines K-K, L-L with each circular deformation 12 surrounded by four ob­long deformations 11.
  • the spacing of the lines K-K, L-L specify the pitch of the deformation array: pitch of 5 mm may be used for example.
  • the structural embossing is achieved by a cold deformation using a suit­able embossment tool e.g. rollers, and it is a feature of the embossment that the orthogonal lines K-K, L-L are oblique to the rolling direction R.
  • a suit­able embossment tool e.g. rollers
  • the longitudinal direction of the flashing (extend­ing vertically out of the plane of the paper in Fig. 6) will correspond with the rolling axis R so that the deformation array 11, 12 will be oblique to the longitudinal axis of the flashing 1 i.e. the orthogonal lines K-K, L-L will be oblique to this axis.
  • the thickness t (Fig. 7) of the wall material remains substantially uniform over the area of the wall even after the embossing process.
  • deformations of other planar shape could be presented in the array of Fig. 6 for example deformations of rectangular or square form could be used. Further, different patterns are possible such as for example a uniform array of similar deformations, and an irregular (non-uniform) deformation array is also possible.
  • Fig. 8 shows a wall portion embossed so as to be of corrugated form with nodes 13, 14 and the ratio of pitch P to valley depth H can be suitably chosen.
  • the axis of deformation (i.e. vertically out of the plane of the paper in Fig. 8) of the profile can be arranged appro­priately relative to the longitudinal direction of the flashing.
  • the profile deformation axis may be arranged parallel to the flashings longitudinal direction as shown in Fig. 1 or transversely as shown in Fig. 2.
  • the embossment has the effect of increasing a structural strength property e.g. bending resistance of the flashing by at least 5 per cent. If plastic and/or zinc coatings are to be applied to the flashing the embossment may be carried out before or after the coating is applied.
  • the thickness of flashing wall may be within the range °25mm to 5mm for example and the flashing can have any suitable length.
  • the embossment increases the strength of the flashing and this will enable a thinner metal to be used thereby lightening the flashing and consequently giving rise to a possible saving in cost since less metal is required.
  • varying quality of metal material may be utilised as the strain hardening and cold deformation of the material due the embossment process mitigates against adverse effects created by the use of varying quality material. Further, the embossing deformations will increase the corrosion resistance of the metal.
  • the deformations 11, 12 can be arranged to project from the flashing so as to be visible externally and this improves aesthetic qualities.
  • the weather face of the profile for example the surface with nodes 13, can be suitably coated with synthetic material and zinc before or after embossment. The stronger structurally embossed flashings will give a stronger more consistent line to a building and will be more aesthetically satisfying.
