Description of an Embodiment of the Invention
Referring to the drawings, Figure 1 shows a panel fixing system 10 for fixing building panels to a supporting structure such as a supporting wall in a concealed way.
The system 10 in this example includes a plurality of building panels 12 that in this example are of compressed fibre cement (CFC) type. In this example, the panels 12 are closely adjacently disposed in a vertical direction, and are spaced from each other in a horizontal direction such that an expressed joint 14 is formed. Typical building panel dimensions are 2400mm x 1200mm; 2700mm x 1200mm and 3000mm x 1200mm. Typical building panel thicknesses are 9mm, 12mm, 15mm and 18mm.
As shown in Figure 2, the system 10 includes a plurality of battens 16 that during use are fixed to the supporting structure and extend in a generally vertical direction. In this embodiment, the battens 16 are top hat type battens that may be formed of aluminium material, although it will be understood that any suitable battens may be used.
As shown in Figures 2 and 3, each panel 12 is attached to the battens 16 using a panel mounting device that includes a first mounting portion, in this example in the form of a bottom rail 18, and a second mounting portion, in this example in the form of a top rail 22. The bottom rail 18 is fixed to the battens 16 in any suitable way, for example using screws 20, so as to extend in a generally horizontal direction. The top rail 22 is fixed to a panel 12 using fixing devices 24 shown more particularly in Figures 4 to 7 so as to extend in a generally horizontal direction. The fixing devices 24 securely fix the top rail 22 to the panel from a rear facing surface of the panel 12 without the need to create a through hole in the panel 12.
The bottom and top rails 18, 22 are configured so that the top rail 22 is engageable with the bottom rail 18 to thereby mount the panel 12 relative to the battens 16. In this example, the bottom rail 18 is configured so as to include a base plate 19 fixed to the battens 16 and a parallel offset plate 21 spaced from the base plate 19 to define a bottom plate gap between the offset plate 21 and the battens 16. Similarly, the top rail 20 is configured so as to include a base plate 23 fixed to the panel 12 and a parallel offset plate 25 spaced from the base plate 23 to define a top plate gap between the offset plate 23 and the panel 12. When the top and bottom rails 18, 22 are engaged with each other, the offset plate of the top rail 22 is disposed in the bottom rail gap, and the offset plate 21 of the bottom rail 18 is disposed in the top rail gap.
In this embodiment, bonding tape, such as Very High Bond (VHB) tape is also disposed between the top rail 22 and the panel 12.
Referring to Figures 4 to 7, an example fixing device 24 is shown. The fixing device 24 includes a first fixing portion 26 and a second fixing portion 28 engageable with the first fixing portion 26.
Figure 4 shows the first fixing portion 26 disposed in an inactive position and Figure 7 shows the first fixing portion 26 in an active position.
The first fixing portion 26 is of typical screw configuration and includes a body portion 27, a head portion 29 and an external screw threaded portion 30.
The second fixing portion 28 includes a body portion 32, a head portion 34 and a cavity 36 that extends from the head portion 34 into the body portion 32. The cavity 36 includes an internal screw threaded portion 38 capable of screw threadably engaging with the external screw threaded portion 30 of the first fixing portion 26. In this example, the body portion 32 also includes an external screw threaded portion 39.
As shown more particularly in Figure 5, which is a view of the fixing device 24 shown in
Figure 4 from below, the second fixing portion 28 also includes at least one slit 40 that extends in a direction generally parallel to the central axis of the fixing device 24. In this example, 4 slits 40 are provided that together define 4 segments 42 and a cross like slit configuration when viewed from below. The slit(s) 40 facilitate movement of the segments 42 outwardly when urged to move by screw threaded engagement of the first fixing portion 26 with the cavity 36, as described in more detail below.
In this example, the head portion 34 of the second fixing portion is provided with a channel 44 that facilitates insertion of the second fixing portion 28 into a suitable blind hole 46 formed in a rear surface of a panel 12, for example using a screwdriver.
The body portion 27 of the first fixing portion 26, and the cavity 36 of the second fixing portion 28 are configured such that when the body portion 27 of the first fixing portion 26 screw threadably engages with the cavity 36, the segments 44 move outwardly and thereby exert a force on internal walls of the blind hole 46 that progressively increases as the body portion 27 of the first fixing portion 26 is progressively screwed into the cavity 36 from the inactive position shown in Figure 4 to the active position shown in Figure 7.
In this way, a strong, secure connection is provided between the fixing device 24 and the building panel 12 even though the building panel is relatively thin.
It will be understood that providing positive screw threaded engagement between the first and second fixing portions 26, 28 of the fixing device 24 ensures that a positive connection is provided between the first and second fixing portions 26, 28 that minimises slippage as the segments 44 move outwardly and thereby exert a force on internal walls of the blind hole 46, and as a consequence, the likelihood of unwanted disengagement of the fixing device 24 from the panel 12 is reduced.
Figure 8 shows a cross sectional view 48 taken along a horizontal plane through the panel fixing system 10 shown in Figure 1 at an intermediate location of a panel 12. Figure 8 shows a supporting structure 50, such as a supporting wall, to which the panels 12 are fixed. Also shown is a vapour permeable membrane 52 that is disposed between the batten 16 and the supporting structure 50.
Figure 8 also shows the panel mounting device 56 that includes the bottom rail 18
(fixed to the batten 16) and the top rail 22 (fixed to the panel 12), and bonding tape 58 that in this example is disposed between the top rail 22 and the panel 12. The bonding tape 58 provides additional fixing strength for the panel 12.
Figure 9 shows a cross sectional view 60 taken along a horizontal plane through the panel fixing system 10 shown in Figure 1 at an expressed joint location 14. As shown, an alternate batten 62 is used at an expressed joint location 14, in this example in the form of a top hat type batten.
The alternate batten 62 includes an expressed joint backing plate 64 that spans the expressed joint 14 between the panels 12 and is disposed adjacent the panels to form a seal at the expressed joint 14. In this example, sealant material 66, such as silicone, is disposed between each panel 12 and the expressed joint backing plate 64.
Figure 10 shows a cross sectional view 70 taken along a vertical plane through the panel fixing system 10 shown in Figure 1 at a joint location 72. As shown, at the joint location 72, a backing strip 74 spans the joint 72 and is disposed between end portions of the panels 12 and the batten 62. Sealing material 66, such as silicone, may also be provided between the end portions of the panels 12 and the batten 62, and for example between an upper side of a lower panel 12 and the backing strip 74.
Referring to Figure 11, an exploded perspective view of the panel fixing system 10 is shown.
During installation, the vapour permeable membrane 52 is fixed to a suitable supporting structure 50, such as a supporting wall, in any suitable way, such as using adhesive, and a sufficient number of vertically extending battens 16 are fixed to the supporting structure 50 through the membrane 52 using a suitable fixing arrangement, such as screws. If a vertically extending expressed joint 14 is desired, 2 types of battens are used, intermediate battens 16 at intermediate locations of the panels 12 and expressed joint battens 62 that span the expressed joints 14. Horizontally extending bottom rails 18 are then fixed to the battens 16, 62 using a suitable fixing arrangement such as screws 20.
Two blind holes 46 are formed in each panel 12 and an upper rail 22 is fixed to each panel 12 by passing a fixing device 24 through a hole in the panel 12, inserting the body portion 32 of the second fixing portion 28 into the blind hole 46, and rotating the first fixing portion 26 relative to the second fixing portion 28 so that the first fixing portion 26 moves from the inactive position shown in Figure 4 to the active position shown in Figure 7, and thereby the segments 42 are caused to move outwardly and create a friction fit with the circumferential surface of the blind hole 46.
A backing strip 72 is also attached to an uppermost rear end portion of the panel 12 and the panel 12 is then mounted relative to the supporting structure 50 by engaging the top rail 22 (fixed to the panel) with the bottom rail 18 (fixed to the supporting structure 50).
A subsequent panel 12 is then mounted adjacent and above the panel 12 such that the adjacent panels span the backing strip 72.
In the claims that follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word "comprise" or variations such as "comprises" or "comprising" is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.
It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other country.
Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.
