Description
-1 A FIBRE CEMENT JOINT Technical Field The present invention relates to the joining of sheet material and more particularly, but not exclusively, to the joining of fibre cement sheet material. 5 Background of the Invention Typically, fibre cement sheets are joined by a fibreglass tape embedded in a joining composition located between the two sheets. The joining composition is typically a low modulus acrylic or styrene acrylic based composition. The above discussed known method of joining sheet material has a number of to problems including: (1) if a gap is left between the sheets it is not uncommon for bulging or peaking of the composition to occur due to changes in the gap between the sheets resulting from environmental changes and/or structural movements; and (2) cracking of the filler material if the sheets are closely butted. is Object of the Invention It is an object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages or to provide a useful alternative. Summary of the Invention There is disclosed herein in combination, a first and a second sheet member, 20 each sheet member having a front and a rear major surface joined by an edge portion, the sheet members being arranged so as to have abutting edge portions, and wherein the sheet members are joined by a tape extending across the abutting edge portions and by a filler material within which the tape is substantially embedded, said tape having a Young's Modulus of at least 1.8 x 103 mega pascals and wherein said edge portions include: 25 a first edge surface extending from the rear surface at an acute angle to said rear surface; and a second edge surface extending from the front surface and joined to the first surface, said second surface relative to said front surface providing a depression to receive said tape and filler material to secure said sheet member to said adjacent sheet 30 member. Preferably said tape has a Young's Modulus of about 2.3 x 103 mega pascals.
-2 Brief Description of the Drawings A preferred form of the present invention will now be described, by way of example only, with reference to the accompanying drawings, wherein: Figure 1 is a schematic side elevation of a sheet member joined to a like sheet 5 member by means of a filler and tape; and Figure 2 is a schematic end elevation of one of the sheet members of Figure 1. Detailed Description of the Preferred Embodiments In the accompanying drawings, there is schematically depicted a first sheet member 10 joined to an adjacent second sheet member 11 by means of a filler 12 and tape 10 13. The sheet members 10 and 11 are preferably fibre cement sheets, each having a major back surface 14 and a major front surface 15. Each sheet 10 and 11 has an edge portion 16 joining the back surface 14 with the front surface 15. The edge portion 16 includes a first edge surface 17 extending to a is second edge surface 18. The edge surface 17 extends from the back surface 14 and is inclined thereto by an acute angle 19. The second edge surface 18 extends from the front surface 15 by an acute angle 20 and extends to the first edge surface 17. As can be seen from Figure 2 the angle 20 is considerably less than the angle 19. For example, the angle 19 may be between 60 and 85 degrees while the angle 20 may be between 5 and 20 20 degrees. The surface 18 extends from the surface 15 so as to provide a depression 21. When joining the sheet 10 to the sheet 11, the sheets 10 and 11 are abutted so that the adjacent surfaces 17 diverge from the abutting portions and provide a cavity 22. The filler material 12 is applied to the cavity 17 and adjacent depressions 21 and the tape 25 13 applied. The filler 12 when cured secures the tape 13 to the abutting sheets 10 and 11. Preferably, the tape 13 is perforated tape so that the filler material 12 can pass therethrough. Typically, sufficient filler material 12 would be applied that a user would be required to level the filler material 12 so that the outer surface thereof is generally co planar with the surfaces 15. 30 Preferably, the tape has a Young's Modulus of at least 1.8 x 103 mega pascals. Preferably, the tape has a Young's Modulus of about 2.3 x 103 mega pascals. Preferably, the tape is perforated so that approximately 3 percent of the area is provided by the perforations. Preferably, the tape has a thickness of about 0.4 mm to about 0.5 mm.
-3 Preferably, the tape is a stiff non-plasticised PVC or polyester tape. One example of the filler is as follows: Raw material Proportion % Quantity Kg/Batch Propylene Glycol 4.35 100 Acrylic Emulsion 21.8 502 Biocide .1 2.14 Dispersant .1 2.14 Surfactant .1 1.3 Aga Ammonia 25% .2 5.14 Thickener .1 3.4 Mica 1.3 30 Clay .4 9.00 Dispersant .04 0.86 Calcium carbonate 65.6 1500 Fungicide .05 1.16 Methyl Ethyl Ketone 1.9 40 Water 3.96 90 Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many 5 other forms.
Claims (3)
1. In combination, a first and a second sheet member, each sheet member having a front and a rear major surface joined by an edge portion, the sheet members being arranged so as to have abutting edge portions, and wherein the sheet members are s joined by a tape extending across the abutting edge portions and by a filler material within which the tape is substantially embedded, said tape having a Young's Modulus of at least 1.8 x 103 mega pascals and wherein said edge portions include: a first edge surface extending from the rear surface at an acute angle to said rear surface; and 10 a second edge surface extending from the front surface and joined to the first surface, said second surface relative to said front surface providing a depression to receive said tape and filler material to secure said sheet member to said adjacent sheet member.
2. The combination of claim 1, wherein said tape has a Young's Modulus is of about 2.3 x 103 mega pascals.
3. The combination of claim 1, substantially as herein described with reference to Figures 1 and 2 of the accompanying drawings. Dated 21 August, 2009 CSR Limited 20 Patent Attorneys for the Applicant/Nominated Person SPRUSON & FERGUSON
