Abstract

In one embodiment, a reinforced fiber cement article comprising a fiber cement piece and a reinforcing fixture bonded to a portion of the fiber cement piece for improving the performance, strength and durability of the fiber cement piece. The reinforcing fiber cement article could be used as or in conjunction with a siding plank assembly, which further comprises an interlocking feature that allows the siding plank to be stacked with other siding planks in a manner such that a uniform and deep shadow line is created. The interlocking feature sets the gauge of the exposed plank face and allows for leveling of the plank during installation. The reinforcing fixture could also serve as a thick butt piece or a plastic spline that produces a deep shadow line. A cementitious adhesive is used to bond the reinforcing fixture to the fiber cement piece.

Claims

1. A reinforced fiber cement article, comprising:

a fiber cement article having a front surface, a back surface, a top surface and a top edge and wherein the front surface and the back surface each have a surface area;

a substantially planar reinforcing fixture having a bonding portion bonded to a localized region on at least one of the front surface and the back surface at said top surface, said substantially planar reinforcing fixture comprising, an extending portion extending beyond said top edge and configured to receive a fastener for securing said article to a structure, and said substantially planar reinforcing fixture being disposed to reinforce at least one area on the fiber cement article and to improve the strength of the fiber cement article; and

a high-shear strength adhesive layer situated between the fiber cement article and the substantially planar reinforcing fixture, wherein the high-shear strength adhesive layer is capable of maintaining the bond between the substantially planar reinforcing fixture and the fiber cement article even after being subjected to five wet/dry cycles of soaking in saturated CaO solution at 60°

F.;

wherein the surface of the substantially planar reinforcing fixture has an area that is less than the surface area of the at least one of the front surface and the back surface to which the substantially planar reinforcing fixture is bonded.

2. The reinforced article of claim 1, wherein the high-shear strength adhesive layer covers the localized region of the front surface of the fiber cement article for bonding the substantially planar reinforcing fixture to the fiber cement article.

3. The reinforced article of claim 1, wherein the high-shear strength adhesive layer covers the localized region of the front surface and the back surface of the fiber cement article for bonding the substantially planar reinforcing fixture to the front and back surface of the fiber cement article.

4. The reinforced article of claim 1, wherein the substantially planar reinforcing fixture has a tensile strength greater than the fiber cement article.

5. The reinforced article of claim 1, wherein the substantially planar reinforcing fixture is more flexible than the fiber cement article.

6. The reinforced article of claim 1, wherein the substantially planar reinforcing fixture is a metal foil.

7. The reinforced article of claim 1, wherein the substantially planar reinforcing fixture is a woven metal mesh.

8. The reinforced article of claim 1, wherein the substantially planar reinforcing fixture is a polymer film.

9. The reinforced article of claim 1, wherein the substantially planar reinforcing fixture is a nailing skirt for attaching and supporting the fiber cement article to the exterior of a building.

10. The reinforced article of claim 1, wherein the fiber cement article is a flat siding plank.

11. The reinforced article of claim 1, wherein the fiber cement article has a hollow extruded profile.

12. The reinforced article of claim 1, wherein the fiber cement article has a length extending from one end to another end of the article and the substantially planar reinforcing fixture extends along the entire length of the article.

13. The reinforced article of claim 1, wherein the high shear strength adhesive is capable of maintaining the bond between the fiber cement article and the substantially planar reinforcing fixture even after being subjected to twenty-five soak/dry or freeze/thaw cycles.

14. The reinforced article of claim 1, wherein the high shear strength adhesive has a viscosity sufficient to penetrate into the fiber cement article at about 200 to 400°

F.

15. The reinforced article of claim 1, wherein the high shear strength adhesive is a hot-melt adhesive.

16. The reinforced article of claim 1, wherein the substantially planar reinforcing fixture is a polymer fabric mesh.

17. The reinforced article of claim 16, wherein the polymer fabric mesh is non-woven.

18. The reinforced article of claim 1, wherein the substantially planar reinforcing fixture has a thickness, width, and length.

19. The reinforced article of claim 18, wherein the length of the substantially planar reinforcing fixture is substantially the same as the length of the fiber cement article.

20. The reinforced article of claim 18, wherein the substantially planar reinforcing fixture is an interlocking member.

21. The reinforced article of claim 20, wherein the interlocking member is a butt piece.

22. The reinforced article of claim 20, wherein the interlocking member is a plastic spline.

23. The reinforced article of claim 18, wherein the thickness of the substantially planar reinforcing fixture is substantially constant along the length and width of the fixture.

24. The reinforced article of claim 1, wherein the fiber cement article is a roofing shake.

25. The reinforced fiber cement article of claim 24, wherein the substantially planar reinforcing fixture is a mesh.

26. The reinforced fiber cement article of claim 25, wherein the mesh is made of a polymer material.

27. The reinforced fiber cement article of claim 1, wherein the fiber cement article has a thickness of less than 5/16 of an inch.

28. The reinforced fiber cement article of claim 27, wherein the thickness of the fiber cement article is about 3/16 of an inch.

29. The reinforced fiber cement article of claim 1, wherein the substantially planar reinforcing fixture is a mesh.

30. The reinforced fiber cement article of claim 29, wherein the mesh is made of fabric.

31. The reinforced fiber cement article of claim 29, wherein the fiber cement article is selected from the group consisting of a roofing slate and tile.
