FACING BUILDING MEMBER

Abstract

A facing building member, a method of forming a facing building member and a method of forming a cladding panel. The facing building member is usable with other building members in forming a cladding panel. The building member has a front face and a rear side, the rear side being profiled by cutting with a water jet so as to provide at least one mechanical key on the facing building member.

Description

Claims

1. A cladding panel comprising a plurality of facing building members mounted on a cementitious backing layer, each facing building member having a front face and a rear side, the rear side being profiled so as to provide at least one mechanical key provided by a rounded dovetail shape recess in the rear side of the facing building member, wherein the cementitious backing layer extends into the rounded dovetail shape recess of each facing building member and extends into joins between adjacent facing building members.

2. The cladding panel as claimed in claim 1, wherein a plurality of mechanical keys are provided by recesses in the rear side of each facing building member.

3. The cladding panel as claimed in claim 2, wherein each of the recesses provides more than one mechanical key.

4. The cladding panel as claimed in claim 1, wherein each facing building member is in the form of a brick facing member, and may be formed by cutting a brick into two or more parts.

5. The cladding panel as claimed in claim 2, wherein each of the recesses extends from between 10 and 60% of the thickness of the facing building member.

6. The cladding panel as claimed in claim 2, wherein the rear side of each facing building member has a regular pattern of recesses, and wherein the recesses are separated by correspondingly profiled projections.

7. The cladding panel as claimed in claim 2, wherein the recesses are separated by correspondingly profiled projections.

8. The cladding panel as claimed in claim 2, wherein the rear side of each facing building member has a recess which extends to one end of the facing building member.

9. The cladding panel as claimed in claim 1, wherein the profile of the rear side is configured with an inclination such that the distance between the rear side and the front face decreases in one or more directions across the respective facing building member.

10. The cladding panel as claimed in claim 1, wherein at least one of the facing building members is in the form of a corner member with a front face and a side face, with at least one mechanical key on the rear side from the front face.

11. A method of forming the cladding panel as claimed in claim 1, the method comprising forming a plurality of facing building members, the rear side of each facing building member being profiled by cutting with a water jet so as to provide the at least one mechanical key, the method further comprising locating the plurality of facing building members in a pattern in a mould, and locating a settable material onto the rear of the plurality of facing building members to form the cladding panel once set, wherein the settable material once set forms the cementitious backing layer on which the plurality of facing building members are mounted, wherein the cementitious backing layer extends into the rounded dovetail shape recess of each facing building member and extends into the joins between adjacent facing building members.

12. The method as claimed in claim 11, wherein the settable material is ultra high performance concrete.

13. The method as claimed in claim 11, wherein the settable material is fibre reinforced.

14. The method as claimed in claim 11, wherein the water jet includes an abrasive.

15. The method as claimed in claim 14, wherein the abrasive includes garnet.

16. The cladding panel as claimed in claim 1, wherein the rear side is profiled by cutting with a water jet so as to provide the at least one mechanical key.

17. The cladding panel as claimed in claim 16, wherein the water jet includes an abrasive.

18. The cladding panel as claimed in claim 17, wherein the abrasive includes garnet.
