Abstract

A clayware rainscreen is constructed from tiles (10) by locating them on horizontal rails (13) fixed by brackets (14) to the inner structure (not shown) to be clad, such as an inner wall or timber frame. The brackets (14) can be slid along the rails (13) suitably to position fixing screws (15). Each tile (10) is supported on a rail (13) by means of a rear nib (12) which has a downstand each corner of which rests on a resilient seating element (16) such that each seating element (16) supports the adjacent nib corners of two adjacent tiles (10). Each rail (13) has a downwardly sloping top surface (25) which sheds water penetrating the gaps (50) in the screen to the front of the screen between seating elements (16). Each tile (10) has a cranked upper end (11) which enters a concavity (20) under the rail above. Each seating element (16) has an upstand (32) and the arrangement is such that a tile (10) cannot be first lifted and then swung out of the screen (arrow A) while seating elements (16) are below it. A tool (36) may be used to slide the seating elements (16) along the rails (13) from beneath the tiles (10) enabling them to be removed. In a preferred embodiment all but one vertical row of tiles are supported by seating elements (16) which have a central partition (35) and the vertical gap (50) between adjacent vertical rows of tiles is filled by spacer elements (40) which are supported by location elements (42) engaging the rails (13).

Claims

AMENDED CLAIMS[received by the International Bureau on 25 May 1998 (25.05.98); original claims 1 and 2 amended; remaining claims unchanged (1 page)]

1. Clayware wall cladding comprising a support structure for clayware cladding plates or tiles (10), the support structure comprising a rail (13) and a plurality of support brackets (14) engaged with the rail (13) so as to prevent relative rotation, each bracket (14) being apertured for the insertion of fixing screws or like members (15) and the rail (13) having a shape such that hanging nibs (12) of clayware plates or tiles (10) may be located over it to hang a horizontal row of said plates or tiles (10) on the rail (13), characterised in that each bracket ( 14) is slidable along the length of the rail ( 13) when engaged with the rail and each bracket (14) is apertured for the insertion of fixing screws or like members (15) at positions which will not be obscured by the rail (13) when the brackets (14) engage the rail (13).

2. Clayware wall cladding as claimed in claim 1 , characterised in that each bracket (14) comprises on one side thereof a pair of vertically spaced channels respectively slideably engageable by a pair of vertically spaced flanges on one side of the rail (13), said apertures being located in portions of the brackets (14) which lie outside said channels.

3. Clayware wall cladding as claimed in either of the preceding claims, characterised in that the rail (13) is of hollow, box-section.

4. Clayware wall cladding as claimed in any one of the preceding claims characterised in that the rail (13) has a downwardly sloping upper surface (25).

5. Clayware wall cladding as claimed in any one of the preceding claims, characterised in that a plurality of seating elements (16) are provided adapted to be positioned in spaced relation along the rail (13) such that each extends between two horizontally adjacent tiles (10) supported by the rail (13).

6. Clayware wall cladding as claimed in claim 5 as appendant to claim 4, characterised in that the arrangement is such that water reaching said sloping surface (25) of the rail (13) will be shed between adjacent ones of said seating elements (16) to a position in front of tiles (10) constituting a horizontal course next below that supported by the rail (13).

7. Clayware wall cladding as claimed in any one of the preceding claims comprising two horizontal courses of similar tiles (10) one above and the other below the rail (13), characterised in that the the lower part of the rail (13) has a downwardly-opening concavity (20) to receive a cranked, upper formation (23) of each tile (10) of the course below the rail (13) such that outer surfaces of the tiles (10) of the two courses lie generally in the same plane.
