Description
CLIP FOR CAST STONE WALL SYSTEM
Field of the Invention The present invention relates to cast stone decorative wall systems and to specialized tenon clips for fastening the cast stone elements to a load supporting wall or structure.
Background Thin stone wall cladding products are available in the marketplace. When installed, an attractive natural stone appearance is presented. However, commercialization of this decorative wall facing option is slow in acceptance in part because of an inability to easily and inexpensively attach the facing stone elements to a vertical wall structure.
Typically in the art, thin stone wall systems are installed by the so-called "lick and stick"
method, which involves the use of epoxy adhesive to secure the thin stone or thin brick to plywood or OSB wall cladding, which involves the use of metal lath with a scratch coat of Portland mortar.
Such an adhered thin stone system is inherently less secure since improper application of the adhesive can lead to stones separating from the wall, which is both a nuisance and a safety problem.
Such adhered thin stone systems are typically only used in lower floor applications of residential and commercial buildings as there is a bias against their use on multi-floor buildings. Further, the adhered thin stone system is not used in conjunction with other wall elements such as drainage board and weather-resistant wrap. Accordingly, thin stone products have in the main been used primarily in commercial building applications.
Date Recue/Date Received 2020-11-04 Various bracket or clip systems have been developed to affix decorative veneer panels made to look like stone to a vertical structural wall. Although useful in particular cases, such systems lack versatility and simplicity, requiring brackets or clips with complicated structures and/or several separate components. Such brackets or clips are difficult to secure to structural walls and require time-consuming alignment of panels.
There remains a need in the art for a more versatile, secure, and mechanically stronger thin stone wall system that is less costly, easier and faster to install and requires less skilled labor.
Summary of the Invention A tenon clip for affixing cast stone elements to a supporting wall surface, according to the present invention, has a U-shaped fastening portion with a first fastening side and opposing sidewalls generally perpendicular to the first fastening side. An anchoring flange extends from each of the sidewalls. The first fastening side has a fastening aperture therethrough for fastening the tenon clip to the supporting wall surface. Each anchoring flange has one or more anchors to secure the tenon clip within the cast stone element.
In another embodiment, the one or more anchors comprises one or more apertures through the anchoring flanges.
In another embodiment, the one or more anchors comprises a tab extending generally perpendicularly from the anchoring flanges.

6 Date Recue/Date Received 2020-11-04 As shown in Fig. 3, the length of the tenon clip 10 is slightly longer than the height of the cast stone element 1, such that the fastening apertures 15 near the ends of the tenon clip 10 are positioned above or below the top or bottom edges 4 or 5 of the cast stone element 1. This permits a fastener to be driven through the fastening aperture 15 into the supporting wall surface with the .. cast stone element 1 in position against the supporting wall surface and any adjacent cast stone elements 1. As shown in Figs. 4 and 5, each successive row of cast stone elements 1 in a cast stone wall system, using the cast stone elements 1 and tenon clips 10 of the present invention, may be positioned resting directly on top of the row below with substantially no space therebetween. The fastening portion 11 of the tenon clip 10 which extends above and below the top and bottom edges 4 and 5 of the cast stone element 1 slides into the space between the rear face 3 of the cast stone element 1 below and the supporting wall surface.
Alternatively, the tenon clip 10 may be shorter than the height of the cast stone element 1. A tenon clip 10 may be positioned at the top edge 4 and another at the bottom edge 5 of the cast stone element 1. The shorter tenon clips 10 may be configured the same as the longer tenon clips 10, which span the entire height of the cast stone element 1, except that they, preferably, do not have tabs 17 at both ends and the fastening portion 11 does not extend beyond the anchoring flanges 14 at both ends. In this embodiment, tabs 17 are positioned substantially at the top or bottom edge 4 or 5 of the cast stone element 1, the fastening portion 11 of the tenon clip 10 extends beyond the same top or bottom edge 4 or 5, and the tenon clip 10 extends towards the other top or bottom edge 4 or 5 by a distance less than the height of the cast stone element 1.
A starter strip may be used to support the bottom row of cast stone elements 1 from below, from above, or from one side. The starter strip has a support flange and a base flange
Alternatively, the tenon clip 10 may be shorter than the height of the cast stone element 1. A tenon clip 10 may be positioned at the top edge 4 and another at the bottom edge 5 of the cast stone element 1. The shorter tenon clips 10 may be configured the same as the longer tenon clips 10, which span the entire height of the cast stone element 1, except that they, preferably, do not have tabs 17 at both ends and the fastening portion 11 does not extend beyond the anchoring flanges 14 at both ends. In this embodiment, tabs 17 are positioned substantially at the top or bottom edge 4 or 5 of the cast stone element 1, the fastening portion 11 of the tenon clip 10 extends beyond the same top or bottom edge 4 or 5, and the tenon clip 10 extends towards the other top or bottom edge 4 or 5 by a distance less than the height of the cast stone element 1.

7 Date Recue/Date Received 2020-11-04 extending from the support flange, preferably, at a right angle. The support flange has one or more apertures for receiving fasteners to attach the starter strip to the supporting wall surface. The base flange may have one or more drainage apertures for permitting moisture to escape from between the cast stone elements 1 and the supporting wall surface. The starter strip has a length long enough to span two or more cast stone elements 1 and, preferably, between about 3' to 12', more preferably, between 4' and 8'.
The starter strip may be straight or curved and may have an L-shaped or J-shaped cross section. Where the tenon clip 10 extends beyond both the top and bottom edges 4 and 5 of the cast stone element 1, a J-shaped starter strip may be used to accommodate the tenon clip 10 extending below the bottom edge 5 of the cast stone element 1. Curved starter strips may be used to span archways, windows, and the like.
Optionally, the tenon clip 10 may be shimmed with reference to the supporting wall surface to leave space between the supporting wall surface and the first fastening side 12 of the tenon clip 10. In this way the spacing between the cast stone element 1 and the supporting wall surface may be selectively adjusted, as required, for example, to accommodate any uneven areas on the supporting wall surface. A shim feature may be provided at the rear of the tenon clip 10, such as a raised flexible indent portion or biasing tab. An installer may incrementally depress the tab to provide the desired spacing.
The vertices of the tenon clip 10, such as the comers of the U-shaped fastening portion 11 and the point at which the anchoring flanges 14 extend from the sidewalls 13, may be structurally reinforced to prevent relative bending between the parts of the tenon clip 10.
