Reinforced fiber cement article and methods of making and installing the same
First Claim
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.

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.
