[0001] The following invention relates to a ventilated wall and more particularly, though
not exclusively to a ventilated wall panel formed from a continuous sheet of corrugated
material having ventilation apertures consecutively staggered between adjacent louvres
of the corrugated material. The invention also relates to a method of manufacturing
such a ventilated wall panel.
[0002] Known louvred walls which aim at allowing ventilation therethrough while preventing
the ingress of rain for example are formed of separate longitudinal metal louvre blades
which are mounted on some form of mounting frame, one above the other. Such a method
of constructing a louvred wall is inefficient in that vertical uprights must first
be provided onto which individual horizontal slats must be separately attached. This
process is labour intensive and expensive.
[0003] Also known are louvre units such as that disclosed in US Patent No. 3302554. Such
a louvre unit comprises a frame surrounding a moulded louvre panel of a discrete size
so as to fit within a frame of a specific dimensions. A disadvantage of such a method
of constructing a ventilated wall panel is that where panels of different size are
required, separate mouldings of appropriate shape and size must be produced. The cost
involved in such moulding is high.
[0004] It is the object of the invention to overcome or substantially ameliorate the above
disadvantages and/or to provide a generally improved ventilated wall.
[0005] There is disclosed herein an elongated ventilation panel of rolled or pressed sheet
metal construction so that lengths may be cut therefrom to form discrete panel modules,
said panel being corrugated to form a series of louvres and ventilation regions interposed
between the louvres, the louvres serving as an impediment to ingress of rain for example
through the ventilation regions.
[0006] There is further disclosed herein a method of manufacturing a ventilation panel so
that lengths may be cut therefrom to form discrete panel modules, said method including
the steps of:
forming a series of ventilation apertures through a sheet of metal, providing forming
means,
passing said sheet of metal having said apertures therethrough through the forming
means to provide elongated corrugations therein, the corrugations running longitudinally
of the sheet and providing louvres and ventilation regions corresponding to said apertures
interposed between the louvres, the louvres in the finished product serving as an
impediment to ingress of rain for example through the ventilation regions.
[0007] Advantageously, such a ventilated panel may be manufactured off-site, cut to size
and erected as a single unit which may in turn result in more time efficient construction
of a finished wall.
[0008] A preferred form of the present invention will now be described by way of example
with reference to the accompanying drawings, wherein:
Figure 1 is a schematic perspective view of a ventilated wall panel, and;
Figure 2 is a more detailed schematic perspective view of the ventilated wall panel
of Figure 1.
[0009] In the accompanying drawings there is schematically depicted a ventilated wall panel
1. Panel 1 comprises a sheet of corrugated material 2 formed into a plurality of adjacent
louvre fins 6 having louvres 3 which are downwardly sloping for drainage purposes.
Each louvre 3 may comprise a longitudinal deformation, such as a dog-leg bend as indicated
at 9, or alternatively, may be substantially planar.
[0010] The wall panel 1 may for example be any form of coated steel or aluminium, either
of which may be zinc coated and painted, mill finished and/or anodised. Alternatively,
the wall panel 1 may be formed of any suitable plastics material.
[0011] Extending essentially horizontally from the outer extremity of each louvre 3 to the
inner extremity of the next below louvre is a ventilation strip 7 perforated so as
to have a plurality of ventilation apertures 4.
[0012] The ventilated wall panel 1 is adapted to be attached by way of bolts for example
to a pair of vertical uprights 5. It should be appreciated that vertical uprights
5 are located on an interior side of wall panel 1 such that the ventilation apertures
4 are protected from downward ingress of water for example due to the presence of
the louvres 3 thereabove.
[0013] The sheet of corrugated material 2 may be formed in continuous lengths, though should
extra vertical extension of the ventilated wall panel be required, a lower edge of
one panel may be overlapped with an upper edge of a downwardly adjacent panel as depicted
at 8 in Figure 2.
[0014] The ventilated wall panel 1 is typically roll formed, though pressing is an alternative
method of forming individual panel lengths. The method of manufacturing the ventilated
wall panel 1, typically comprises punching apertures 4 in desired locations in a flat
elongated sheet of metal or other suitable material. Once the apertures 4 are punched
in the metal sheet, the sheet may be formed into the corrugated configuration depicted
by conventional roll forming techniques.
[0015] If the sheet is to be manufactured by pressing, the sheet again would be punched
to provide the apertures 4, and then pressed to have the corrugations.
[0016] Ventilation apertures 4 being provided in the essentially horizontal strip 7 may
be of any suitable shape such as the elongate slots depicted, or circular for example.
The holes 4 would preferably be punched in the sheet material before forming to the
corrugated configuration.
[0017] It should be appreciated that modifications and alterations obvious to those skilled
in the art are not to be considered as beyond the scope of the present invention.
For example, the wall panel 1 need not be attached to a vertical support bracket 5
as depicted, though edges of panel 1 may be located within a recess of a suitable
U-section for example.
