Abstract

The Alu-Eave system is easily installed in standard residential installations without the need to change the facia if used with a standard grooved facia profile. The Alu-Eave system reduces installation time for eaves up to 600mm compared to soft sheet eave lining, because the support for the eave sheet is also the trim. The Alu-Eave system has a seamless transition from existing installation methods to new requiring only minimal re-training for trades. It utilises the standard grooved facia which is commonly used in the building industry. The aluminium trim is also the supporting structure for the eave sheet for eaves up to 600mm wide. Alu-Eave custom Jointer trim used to join Alu-Eave sheets together, it is designed to slide onto sheet then allow next sheet to sit on it. VSB double sided tape is used to keep the second sheet in place. Alu-Eave custom Concealer trim is used to finish against brick veneer/cladding when using concealed framing. VSB double sided tape is used to keep the trim in place. Alu-Eave custom standard trim used for support and trim of sheets against brick veneer or cladding. Heavy Duty Exterior double sided tape, compatible for brick work, is used to aid the mechanical fixing to brickwork or cladding.

Alu-eave. aluminium composite sheet eave lining system for standard residential eaves
Field of Invention
This invention relates to eave lining systems and more particularly to eave 5 lining systems that do not require fasteners to pass through the eave sheets.
Background
In most residential buildings fibre cement sheets are secured to the support structure nailing or screwing through the eave sheets.
It is desirable to provide eave sheets that have a pleasant finished look. Whilst 10 not limited to such eave sheets, it is desirable to ab able to use aluminium composite panels as eave sheets in residential situations.
Summary of the Invention
In one broad form the invention provides an eave system for a building having an exterior wall and a roof structure that extends beyond the exterior wall, 15 the roof structure having a generally horizontal groove spaced from and facing the exterior wall; a support member secured to the exterior wall and having an upper surface extending generally horizontally away from the exterior wall toward the groove; 20 comprising adjacent first and second eave sheets extending from the groove to or adjacent the exterior wall and each having a first peripheral edge portion extending into and supported by the groove and a second peripheral edge portion of the at least one eave sheet resting 25 on and supported by the upper surface, a gap between adjacent edges of the first and second eave sheets and a joiner 2015100667 09 Dec 2016 4823-20161209-description.docx - 2 - located in the gap, the joiner having a central web extending along the gap; a first arm extending transversely from the central web to lie underneath a portion of the first eave sheet; 5 a second arm extending transversely from the central web to lie underneath a portion of the second eave sheet; a third arm extending transversely from the central web to lie over a portion of the first eave sheet, and wherein the joiner does not extend over the second eave sheet 10 whereby immediately upon insertion into the groove and supporting upon the support surface the or each eave sheet can be installed in a finished state.
The support member may comprise a length having, in cross section, two perpendicular arms, a first arm extending generally horizontally and defining the upper surface and a second arm extending generally vertically upwards 15 from the first arm for securement to the exterior wall.
The eave system may include a stiffening member separate from the roof system that extends at least part way between the groove and the support member above an upper surface of the at least one eave sheet, the stiffening member being secured to the upper surface of the at least one eave sheet 20 with adhesive.
The stiffening member may be hung from the roof structure.
Preferably when installed the eave sheet(s) do not require fasteners to pass through the eave sheet.
These and other features of the invention will be more apparent from the 25 following non limiting description of preferred embodiments with reference to the accompanying drawings. 4823-20161209-description.docx 2015100667 09 Dec 2016 - 3 -

Detailed Description of Preferred and other Embodiments
The system I have come up with allows aluminium composite panel to be installed as eave lining in standard residential homes. 15 It utilises the standard grooved facia which is commonly used in the building industry.
The aluminium composite sheet product has two pre finished faces.
The trims are powder coated aluminium.
The aluminium trim is also the supporting structure for the eave sheet for 20 eaves up to 600 mm wide.
Concealed ceiling system or similar framing for eaves over 600 mm wide is used for the structure.
Alu-Eave custom Jointer trim used to join Alu-Eave sheets together, it is designed to slide onto sheet then allow next sheet to sit on it. VSB double 25 sided tape is used to keep the second sheet in place.
Alu-Eave custom Concealer trim is used to finish against brick veneer/cladding when using concealed framing. VSB double sided tape is used to keep the trim 4823-20161209-description.docx 2015100667 09 Dec 2016 - 4 - in place.
Alu-Eave custom standard trim used for support and trim of sheets against brick veneer or cladding.
Heavy Duty Exterior double sided tape, compatible for brick work, is used to 5 aid the mechanical fixing to brickwork or cladding.
All Alu-Eave trims will preferably have the appropriate double sided tape preinstalled.
Figure 1 shows a schematic view of an eave lining installation according to a first embodiment of the invention. 10 A building 10 has an external wall 12, a roof structure 14 and a standard facia board 16. The standard facia board 16 has a standard groove 18 for receiving a standard eave sheet.
Mounted on the wall is a support bracket 20, shown in more detail in figure 2, which includes a support surface 22. 15 A series of eave lining sheets 24 are supported side by side with their outer edges 26 supported in the groove 18 and their inner edges 28 supported on the support surface 22.
In this implementation, the separation between the wall 12 and facia board 16 is usually no more than 600 mm, but this depends on the stiffness of the eave 20 sheets 24.
The eave sheets will rest on the support surface under gravity but to prevent the sheets being accidentally moved it is preferable that they be secured to at least the support surface using a strip 30 double sided tape.
Referring to figure 3, adjacent side by side sheets 24A and 24B are joined to 25 each other by joiner 34. The joiner 34 serves to cover the gap 36 between the sheets and also support and maintain the two sheets together and prevent one sheet dropping or sagging relative to the other sheet.
Because the preferred method of fixing the sheets is with adhesive it is not 4823-20161209-description.docx 2015100667 09 Dec 2016 - 5 - feasible to slide the sheet 24B relative to the joiner 34.
Accordingly the first sheet 24A is installed and supported on facia 16 and support bracket 20. The joiner 34 is than mounted on the first sheet 24A. The joiner has lower flange 38 and upper flange 40 that extend from central flange 5 42 and define a slot 44 that is sized to receive the side edge portion 46 of the first sheet 24A. A single lower flange 48 extends from central flange 42 in the opposite direction from lower flange 38.
The lower flange 48 is provided with a strip 50 of double sided tape on its 10 upper surface 52.
To install the second sheet 24B, the installer inserts the outer edge portion 26 into groove 18 whilst maintaining the sheet angled with the inner edge portion raised above the support bracket 20. This maintains the side edge region 54 above the double sided tape 50. The sheet 24B may be slide sideways until 15 positioned correctly. Typically this will involve the edge region 54 contacting part of the central flange 42 at the outer edge. The installer then lowers the inner edge portion 28 until the sheet rests on the adhesive 30 and 50 and is secured in place.
Where the side of an end sheet is against a portion of brick veneer or cladding 20 the support bracket 20 may be used to support and conceal the gap between the sheet and the brick veneer or cladding.
Figure 4 shows a concealer trim 60. This is used where the side of an end sheet is against brick veneer or cladding when using concealed framing. The trim 60 has a lower flange 62 and a vertical flange 64. A strip 66 of double sided tape 25 is located on the flange 62. The trim 60 is secured against the sheet with the double sided tape 66 and with the two flanges covering any gaps.
The eaves sheets typically used are self-supporting for spans up to about 600 mm; wider spans usually require additional support.
Figure 5 shows an arrangement typically used for spans greater than 600 mm 2015100667 09 Dec 2016 4823-20161209-description.docx - 6 - wide. The same components are used as in the figure 1 embodiment and the same numerals are used. The eave sheet 24 is supported on the support bracket 20 and in groove 18. However, support trim 80 is secured to the upper surface 82 of the sheet 24 with a strip of double sided tape 90. Preferably the 5 trim 80 extends the full width of the sheet. Support members 92 extend from the roof structure to the trim 80.
