2. Description of Related Art
Various architectural finish elements have been used over the years to clad architectural structures such as buildings. Some of these architectural finish elements involve individual stone elements, individually secured to the architectural structure. Installation of this type of element is time-consuming, and such elements can be susceptible to release from the surface due to thermal expansion and contraction, which can loosen mortar adhesion systems that secure such elements to an architectural structure for example. Further, such individually secured stone elements are often joined by mortar joints having thicknesses of about ⅜ inches or more, and such mortar joints may have an undesirable appearance.
Some inventors have overcome the mortar adhesion problem by cutting grooves into the individual stone elements and using a support clip that cooperates with the groove to support the individual stone element, but this tends to secure the stone elements rather rigidly to the surface of the architectural structure, which can still be a problem due to wind loading and seismic loading. Forces due to these conditions can result in displacement of the individual stone elements from the clips, resulting in release of one of more of the stone elements from the structure.
The appearance of dry-stacked individual stone elements (i.e. where there are no readily apparent joint lines between adjacent stone elements) is a highly desirable and attractive finish and is generally achieved only by actually dry stacking individual stone elements. Generally, individual stone elements are not aggregated together into unitary collections to form an architectural finish element because the stone elements themselves are generally relatively heavy such that any unitary collection of stone elements is generally too heavy to be lifted by a single person and would be too heavy to meet many building codes. To reduce weight, individual stone elements may sometimes be secured to a foam backing for example, but the foam can deform over time if subjected to point loading and can be susceptible to ultraviolet radiation degradation and can present challenges for fire proofing.
Artificially formed surfaces comprised of concrete painted and molded to look like a dry-stacked arrangement of individual stone elements have been used on foam to form building blocks but are still too heavy and therefore not suitable for cladding a building. Patio and walkway surfaces have been paved by masonry panels comprising a reinforced series of masonry elements such as stone or brick pavers bound together by a cement or mortar-like material, but these too are too heavy for cladding an architectural structure.
In accordance with one aspect of the invention, there is provided an architectural finish element operable to be placed adjacent similar architectural finish elements to form a finished surface on an architectural structure.

Other aspects and features of the present invention will become apparent to those ordinarily skilled in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures.

Referring to
In this embodiment, the rock-based composite material forming the body 12 is comprised of Portland cement mixed with water and an aggregate comprised of pumice in a ratio of 1.5:1:2. In this embodiment, the veneer elements, such as shown at 16, 18 and 20 for example, may be bonded to the body 12 by casting the body adjacent the veneer elements.
The solid particle additive 14 may be recycled waste, non-toxic waste, post manufacturing waste, or post consumer waste, for example, such as is available under the trade name Re-Ad from CLP Technologies, LLC of Seattle, Wash., USA.
Alternatively, or in addition, the solid particle additive 14 may comprise lightweight synthetic particles such as polymer particles available from Syntheon Inc. of Moon Township, Pa., USA under the trade name Elemix.
The body 12 is formed such that it comprises about 25% to about 50% of the low density solid particle additive 14 by volume and such that the rock-based composite material and the low density solid particle additive are provided in amounts suitable to cause the body to have a density of no more than about 4 pounds per square foot. The real stone veneer elements 16, 18, 20 are cut thinly such that they add no more than about 6 to 11 pounds per square foot so that the completed architectural finish element will have a density of between about 10 pounds per square foot to about 15 pounds per square foot. This provides a panel of a weight suitable for manipulation by most persons and one that complies with most building codes.
At the time of manufacture, the unitary real stone veneer elements 16, 18, 20 are bonded to the body 12 in courses 22, 24, 26, 28, for example, extending in a first direction 30 and in a random non-repetitive pattern. The real stone veneer elements 16, 18, 20 are bonded to the body 12 such that a spacing 32 between adjacent courses is generally between 0 inches to about ¼ inches and such that respective face surfaces of the unitary real stone veneer elements generally lie in a common plane to form an overall face surface 34 of the architectural finish element, causing it to have a dry-stacked appearance. A dry-stacked appearance is one in which the individual stone veneer elements 16, 18, 20 are arranged so closely together that there are no “mortar” lines or “mortar joints”, i.e. gaps between adjacent such elements.

The architectural finish element may be directly secured to a flat surface of the architectural structure by placing wet mortar on the flat surface and then setting the architectural finish element into the mortar, like a wall title.
The above-described architectural finish element provides a body 12 with an overall face surface 34 provided by a unitary collection of real stone veneer elements 16, 18, 20 having a dry-stacked appearance. In the embodiment shown, the overall length of the architectural finish element is about 30 inches and the height is about 8 inches. Each projection 60 and 62 extends about 4 inches from the main body and has a height of about 4 inches. The use of an architectural finish element according to the specific embodiment described provides about 1.33 square feet of coverage to the architectural structure and can be applied as a unit, avoiding individual placement of real stone veneer directly on the architectural structure. This enables rapid application of a finishing surface or outer cladding to an architectural structure 1.33 square feet at a time, rather than direct application of real stone veneer elements that cover only a few square inches at a time, while still achieving a dry-stacked appearance.
The courses of the unitary real stone veneer elements 16, 18, 20 are bonded to the body 12 such that upper and lower edges 100 and 102 of left side veneer elements, one of which is shown at 16 adjacent the left edge 46 of the body 12, are generally the same distances from the bottom edge 44 of the body as corresponding upper and lower edges 104 and 106 of veneer elements adjacent the right edge 48 of the body such that when the left edge 52 of a first similarly configured adjacent architectural finish element 56 is engaged with the right edge 50 of the architectural finish element 10, corresponding courses of real stone veneer elements 16, 18, 20 are aligned to create the appearance of continuous courses of the real stone veneer elements across the architectural finish element 10 and the similarly configured adjacent architectural finish element 56. Similarly, when a right edge 50 of a second similarly configured adjacent architectural finish element 54 is engaged with the left edge 46 of the architectural finish element 10, corresponding courses of real stone veneer elements are aligned to create the appearance of continuous courses of the real stone veneer elements across the architectural finish element and the second architectural finish element 54. In addition, referring to
In the embodiment shown in
The architectural finish element 120 may be directly secured to a flat surface of the architectural structure by placing wet mortar on the flat surface and then setting the architectural finish element into the mortar such that the mortar becomes disposed between adjacent tenons and in contact therewith. When the mortar sets, it takes the shape of a complementary dovetail engaged with the dovetailed tenons of the architectural finish element and thus the dovetailed tenons of the architectural finish element are held securely by the mortar, which causes the architectural finish element to be secured to the surface of the architectural structure.

The mounting portion 164 comprises a generally planar sheet portion 180 of the sheet metal body having a flat surface 182, which in some embodiments may rest against the surface of the architectural structure, although in other embodiments the flat surface 182 may be spaced apart from the surface of the architectural structure. The mounting portion 164 cooperates with a load absorber shown generally at 183 that is operably configured to absorb mechanical forces between the mounting portion 164 and the architectural structure 11. The load absorber 183 includes a load absorbing member 184, a fastening bar 186 and a fastener 188 to secure the body 162 to the architectural structure.
The mounting portion 164 includes a force absorbing member holder 190 formed into the mounting portion of the sheet metal body.
The force absorbing member holder 190 has a wall 192 defining an opening 194 in the mounting portion 164, such that portions of the sheet portion about the opening define margins 196 and 198 around the opening. In the embodiment shown the opening 194 has a rectangular shape with first and second long side portions 197 and 199 and first and second short side portions 200 and 202. The force absorbing member holder 190 also has first and second guides 204 and 206 extending in parallel spaced apart relation from the wall 192 and disposed adjacent the first and second long side portions 197 and 199 of the opening 194 for holding a portion of the force absorbing member 184 in the opening and for holding another portion thereof between the guides. The guides 204 and 206 may be formed by cutting an ‘h” form having a center cut into the planar mounting portion 164 of the body 162 and then bending solid portions on opposite sides of the “h” form to extend parallel to each other, perpendicularly to the plane of the mounting portion.
In this embodiment, the force absorbing member 184 comprises a resilient body 210 comprised of Neoprene®. The resilient body is formed to include a first aligner 212 operably configured to align the force absorbing member 184 in the opening 194 and a second aligner 214 operably configured to align the force absorbing member 184 against the guides 204 and 206. The first aligner 212 includes a projection 216 on the force absorbing member 184, the projection 216 having a flat outer surface 218 for bearing against the surface of the architectural structure and having a shape complementary to the shape of the opening 194 which, in the embodiment shown, is rectangular. The second aligner 214 comprises a rectangular holding portion 220 on the force absorbing member adjacent the projection 216 and having first and second opposite end portions 222 and 224 extending outwardly on opposite sides of the projection 216 such that the first and second opposite end portions overlap with corresponding margins 196 and 198 of the sheet portion on opposite short side portions 200 and 202 of the opening 194 when the projection 216 is received in the opening 194.
The load absorber fastening bar 186 has a bearing surface 230 having a shape corresponding to the shape of the holding portion 220 of the force absorbing member (i.e. rectangular). The fastening bar 186 also has an opening 232 for receiving the fastener 188. The fastener 188 is operable to extend through the fastening bar 186 and through the force absorbing member 184 and into the surface of the architectural structure as shown in
The first holder 166 includes a first projection 250 operably configured to project upwardly when in use and operable to be received in the groove 156 in the bottom edge 150 of the architectural finish element.
The first holder 166 also includes a first receptacle 252 spaced apart from the mounting portion 164 and terminated in the first projection 250. The first receptacle 252 holds a portion of the bottom edge 150 of the architectural finish element 140 in a position spaced apart from the surface of the architectural structure. More particularly, the first receptacle 252 holds the inner projection 154 on the bottom edge 150 of the architectural finish element, while the first projection 250 is received in the groove 156 between the inner and outer projections 154 and 152 on the bottom edge 150.
To facilitate use of the dual architectural finish element support apparatus 160 in areas of the architectural finish element 140 which have dovetailed tenons, at least some of the dovetailed tenons 158 are configured with a recess 159 to receive the guides 204 and 206 extending from the mounting portion 164. In this case, the tenons 158 are configured to extend from the top edge 142 of the architectural finish element 140 to near the bottom edge 150 but not completely to the bottom edge. Rather, lower end portions 270 of the tenons 158 are spaced apart from the bottom edge 150 by the distance between the first receptacle 252 and a top 272 of the mounting portion 164, leaving only a planar surface portion 274 of the rear surface of the architectural finish element exposed in this area. The enables the entire mounting portion 164 to be received in the space defined by the lower end portion 270 of the tenon 158, and the planar surface portion 274 between the lower end portion of the tenon and the bottom edge 150 of the architectural finish element. In addition, the guides 204 and 206 on the dual architectural finish element support apparatus 160 are configured such that their distal surfaces 260 and 262 touch the flat planar surface 274 between the lower end portion 270 of the tenon 158 and the bottom edge 167 of the architectural finish element 140. In addition, distal flat surfaces 280 of the tenons 158 touch the flat surface 282 of the architectural structure. This provides for additional support.
The second holder 168 includes a second projection 290 operably configured to project downwardly when in use, in a direction opposite to the first projection 250 and operably configured to bear against a portion of a top edge 169 of the second architectural finish element 170. In particular, in this embodiment, the second projection 290 is configured to bear against the second flat top surface 146 and a vertical surface 292 between the first and second flat top surfaces 144 and 146 of the second architectural finish element 170 such that the top edge 169 of the second architectural finish element is aligned with the bottom edge 167 of the architectural finish element 140 held by the first receptacle 252 and first projection 250.
When architectural finish elements 140 and 170 of the type described are secured to the architectural structure in the above manner, adjacent tenons 158 and the planar surface portions 274 between adjacent tenons form air passageways 300 that extend parallel to the tenons and permit air to move therein, in a direction generally parallel to the orientation of the tenons. This enables moisture that may ingress between adjacent architectural finish elements 140 and 170 to reach an air passageway 300. Such air passageways 300 formed by respective vertically adjacent architectural finish elements 140 and 170 are in communication with each other and facilitate airflow vertically along the passageways, which facilitates drying of moisture therein, thereby impeding moisture from reaching the architectural structure to which the architectural finish elements are attached. Thus, the tenons 158 act as integral moisture path interference structures operably configured to interfere with seepage of moisture from between adjacent architectural finish elements toward the architectural structure.

Causing the first holder 166 on the body 162 to hold a portion of a bottom edge 167 of the first architectural finish element 140 comprises causing the first projection 250 on the first holder 166 to be received in the groove 156 in the bottom edge 167 of the first architectural finish element 140 and holding the bottom edge 167 of the first architectural finish element 140 in a position spaced apart from the surface 111 of the architectural structure 11.
The method further involves causing coplanar distal surfaces 260 and 262 of the guides 204 and 206 to touch the planar surface portion 274 on a back side of the first architectural finish element 140 to position the first architectural finish element on the surface 111.
The method further involves causing the second projection 290 on the body 162 to bear against a portion of the top edge 169 of the second architectural finish element 170.
Although the method described above involves a dual architectural finish element support apparatus 160, in alternative embodiments, architectural finish element such as those illustrated in

Thus, in this embodiment, like the earlier embodiment, the body 404 has main portion 412 and top, bottom and left and right edges 414, 416, 418 and 420. The left and right edges 418 and 420 have complementary shapes for engaging with corresponding right and left edges of left and right adjacent similar architectural finish elements respectively as described above. In the embodiment shown, the left and right edges 418 and 420 of the body 404 have a complementary stepped-shape, wherein the left edge has an upper projection 422 and the right edge has a lower projection 424, both projecting from the main portion 412 by the same distance, to as to form a lower receptacle 426 on the left side of the main portion 412 and an upper receptacle 428 on the right side of the main portion 412. As above, this permits a lower projection of an adjacent left element (not shown) to be received in the lower receptacle 426, while the upper projection 422 of the left edge is received in an upper receptacle (not shown) of the adjacent left element. Similarly an upper projection (not shown) of the adjacent right element (not shown) is received in the upper receptacle 428, while the lower projection 424 of the right edge 420 is received in the lower receptacle (not shown) of the adjacent right element.

The courses of the unitary real stone elements 402 are glued together such that upper and lower edges of left side stone elements 402 adjacent the left edge 418 of the body 404 are generally the same distance from the bottom edge 416 of the body as corresponding upper and lower edges of right side veneer elements adjacent the right edge 420 of the body such that when a left edge (not shown) of a first similarly configured adjacent architectural finish element (not shown) is engaged with the right edge 420 of the architectural finish element 400, corresponding courses 406 of real stone veneer elements are aligned to create the appearance of continuous courses of the real stone veneer elements across the architectural finish element 400 and the similarly configured adjacent architectural finish element and such that when a right edge (not shown) of a second similarly configured adjacent architectural finish element (not shown) is engaged with the left edge 418 of the architectural finish element 400, corresponding courses of real stone veneer elements are aligned to create the appearance of continuous courses of the real stone veneer elements across the architectural finish element and the second architectural finish element. In addition, due to the engagement of the stepped left and right edges 418 and 420 and the engagement of the top and bottom edges 414 and 416 with adjacent architectural finish elements, and due to the consistent placement of the real stone elements 402 in courses aligned at each edge, as described above, when a plurality of such architectural finish elements are engaged as described to form an overall surface on the architectural structure, the resulting overall surface has a consistent, uniform dry-stacked appearance with the randomness of stones in respective courses, but with the regularity of courses along the entire finished surface, in a manner similar to that described and shown in connection with
