Description

PANELIZED VENEER WITH BACKER-TO-BACKER LOCATORS

TECHNICAL FIELD AND INDUSTRIAL APPLICATBILITY OF THE INVENTION

This invention relates generally to the construction field and, more particularly, to a cast veneer wall panel, a backing panel for a cast veneer wall panel and a method of making a cast veneer wall panel.

BACKGROUND OF THE INVENTION

Cast veneer wall panels have been developed as a quick and efficient way to provide a masonry appearance for a building while simplifying construction and lowering construction costs. Such panels typically include a front plate or panel carrying a series of design or masonry elements. These design elements simulate brick, stone, tile and other masonry building components or materials commonly used in the construction of buildings. Examples of cast veneer wall panels are disclosed in U.S. Patent 3,332,187 to Arcari and co-pending U.S. Patent Application Serial No. 11/647,679, entitled "Fiber Reinforced Concrete Stone Panel System" owned by the assignee of the present invention and incorporated herein by reference.

Cast veneer wall panels are typically made from reinforced construction materials such as fiberglass reinforced concrete. While cast veneer wall panels made from such reinforced materials are more resistant to damage from handling during packaging, shipping and installation, further improvements in durability to reduce loss due to breakage are still desired. The present invention relates to a cast veneer wall panel of enhanced durability providing significantly improved handling characteristics due to light weight construction and ability to fasten by nailing. The cast veneer wall panel is also easier and quicker to orient, seat and install.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

Reference is now made to Figures 1-2 illustrating the cast veneer wall panel 10 of the present invention. As illustrated, the cast veneer wall panel 10 comprises a backing panel 12 and a facing panel 14. The body of the backing panel 12 includes a rear face 16 and a front face 18. As further illustrated in Figure 3, the front face 18 includes a boundary wall 20 that at least partially encircles a casting field 22. More specifically, the wall 20 comprises a raised lip or ridge.

The backing panel 12 may be made from any suitable material such as wood, treated wood, metal, such as galvanized steel, aluminum, copper or as a single molded piece from a polymer material or a composite material. Polymer materials useful for making the backing panel 12 include various thermoplastic and thermoset resins, including but not limited to polyolefins, polyesters, polyvinyl chloride, polypropylene, polyethylene, polyamide, epoxy, vinyl ester, acrylic, polystyrene, ABS, melamine and mixtures thereof. Composite materials used to make the backing panel 20 include reinforcing material and a matrix binder. Appropriate reinforcing materials useful in the present invention include but are not limited to glass fibers, natural fibers, mineral fibers, basalt fibers, carbon fibers, kanaf fibers, jutte fibers, hemp fibers, E-glass fibers, C-glass fibers, R-glass fibers, S-glass fibers, ECR-glass fibers, AR-glass fibers and mixtures thereof. It should be appreciated that substantially any type of glass fiber may be used for reinforcement fibers. Glass fibers appropriate for use in the present invention may be loose chopped strand or glass mat and include those available from Owens Corning with headquarters in Toledo, Ohio, under the trademarks Hypertex and Advantex. Matrix binder materials useful for this purpose include but are not limited to polyolefins, polyesters, polyvinyl chloride, polypropylene, polyethylene, polyamide, epoxy, vinyl ester and mixtures thereof. The facing panel 14 is formed from a cast material received and preferably held within the casting field 22 by the upstanding, encircling boundary wall 20. The facing panel 14 includes at least one design element 24. In the illustrated embodiment the cast veneer wall panel 10 includes a series of a masonry or design elements 24. The design elements 24 are illustrated as simulated bricks aligned in a regimented pattern in accordance with standard masonry practices. In other embodiments, the design elements 24 comprise stones, such as ledgestones, limestone, or substantially any other stone texture available for example from Owens Corning of Toledo, Ohio under the Cultured Stone® brand. The facing panel 14 also includes a mortar bed area 26 between the design elements 24. Following installation the mortar bed area 26 is typically grouted by injecting mortar between the design elements 24 so as to provide a finished masonry appearance. In an alternative embodiment, certain textures may resemble a dry stack, and not include the mortar.

While the design elements 24 illustrated in the drawing figures correspond to simulated bricks, it should be appreciated that substantially any other masonry material known in the art may be simulated including bricks of different sizes, stones of different shapes and sizes, tiles of different shapes and sizes and the like. The facing panel 14 is made from a cast material such as concrete, reinforced concrete, reinforced cementitious material and mixtures thereof. Typically the cast material reinforcement comprises fibers selected from a group of materials consisting of glass fibers, mineral fibers, natural fibers, polymer fibers and mixtures thereof. Where glass fibers are used they are typically of the E-glass or AR-glass type, which exhibit some alkali resistance.

As best illustrated in Figure 4, the rear face 16 of the backing panel 12 preferably includes a series of concavities 28, and the front face 14 includes a series of corresponding, projecting pads 30 that nest within the design elements 24 of the facing panel 14. More specifically, during production of the cast veneer wall panel 10, some of the cast material enters the concavities 28 through the apertures 32 in the wall of the backing panel defining the concavities 28 and pads 30 (note set cast material 34 illustrated in Figure 2 that keys the panels 12, 14 together). The cast material 34 wraps around the margins of the backing panel 12 surrounding the apertures 32. When this cast material sets, the facing panel 14 and backing panel 12 are securely fastened together. As best illustrated in Figure 3, a continuous abutment 36 is formed by the boundary wall 20 and a wall portion of several of the concavities 28/pads 30. As illustrated, the abutment 36 extends completely around the perimeter of the casting field 22. The abutment 36 effectively maintains the casting material used to make the facing panel 14 inboard of the abutment on the casting field 22. At the same time, the abutment 36 provides a continuous abutment face 37 free and clear of any cast material. Such an abutment face 37 allow a better fit and finish in a manner described in greater detail below. In an alternative embodiment, the abutment 26 is provided in a substantially continuous manner. In yet another embodiment, the abutment 36 may be provided in a discontinuous manner to provide a discrete mating surface at each interface to an adjacent panel.

As best illustrated in Figures 3-5, the backing panel 12 further includes a mounting flange 44 that extends beyond a first portion 38 of the continuous abutment 36. A series of locating slots 46 are provided in the first portion 38 of the abutment 36. In the illustrated embodiments each of the locating slots 46 extends into the mounting flange 44 and also communicates with the adjacent concavities 28 through the walls of the pads 30.

The backing panel 12 further includes a series of locating tabs 48 that project from a second portion 40 of the continuous abutment 36. The second portion 40 is opposite the first portion 38 of the abutment 36. When the cast veneer panel 10 is properly installed on the framework of a building (see Figure 2), the first portion 38 is provided at the top of the cast veneer panel 10 while the second portion 40 is provided at the bottom or base. Thus, adjacent panels may be retained by an adjacent panel in an in/out relationship relative to the vertical wall, and/or in a side -to-side (lateral) manner with respect to an adjacent panel.

As best illustrated in Figure 4, the rear face 16 of the backing panel 12 is provided with a series of spaced dimples 50. The dimples 50 project outwardly from the rear face 16 in order to provide an appropriate air gap G between the panel 10 and the sheeting S of the building framework in order to allow for moisture dissipation (see Figure 2). In the illustrated embodiment, a row of dimples 50 are provided along the rear of the mounting flange 44. The dimples 50 have a depth of approximately 0.125 inches and provide a minimum flow area of about 65%. Additional dimples 52 are provided at spaced locations along the rear face 16 between the concavities 28. Obviously, the dimples 50, 52 may be cut down or ground down as necessary in order to compensate for any bowing or deviation in the sheeting S that might otherwise cause a wall panel 10 to seat improperly.

Reference is now made to Figures 2, and 4-6 illustrating the installation of one cast veneer wall panel 10 over another cast veneer wall panel 10' previously installed to the sheeting S of a building. The first cast veneer wall panel 10' is properly positioned on the sheeting S. A series of nails or other fasteners F are then driven through the mounting flange 44 into the sheeting S and any underlying wall studs (not shown) in order to secure the first cast veneer wall panel 10' in position. The installer places the second cast veneer wall panel 10 over the first cast veneer wall panel 10' by initially aligning the locating tabs 48 at the bottom of the wall panel 10 in the locating slots 46 at the top of the wall panel 10'. The top edge of the wall panel 10 is then pivoted toward the sheeting S and the locating tabs 48 on the wall panel 10 drop fully down into the locating slots 46 on the wall panel 10' until the wall panel 10 is fully seated with the second portion 40 of the abutment 36 of the top wall panel 10 resting on and abutting the first portion 38 of the abutment 36 of the lower wall panel 10' (see Figure 6). The cooperating locating slots and tabs 46, 48 ensure that the two wall panels 10, 10' are properly oriented so that each row of design elements 24 is properly staggered. At the same time, the continuous abutment 36 ensures that the abutment face 37 around each backing panel 12 is presented for direct contact/abutment with the abutment face 37 of any adjacent panel. As a consequence, no cast material interferes with the manufactured fit of the wall panels 10, 10'. By avoiding any cast material-to-cast material contact between adjacent wall panels 10, 10', it is possible to maintain closer dimensional tolerances and thereby provide a better fit and finish.

Once the wall panel 10 is properly seated on the wall panel 10' with the locating tabs 48 fully received in the locating slots 46 and the ridges 20 of the two panels in abutting engagement (see Figure 2), the installer uses fasteners F driven through the mounting flange 44 of the wall panel 10 in order to secure the new wall panel 10 in position. Significantly, it should be noted that the interlocking locating slots 46 and locating tabs 48 on the wall panels 10, 10' mean that fasteners only need be provided in the mounting flanges 44 at the top of each wall panel in order to secure a wall panel in position. No fasteners are required along the bottom. This simplifies the installation process and allows a wall panel 10 to be installed in a shorter period of time. While not illustrated, it should be appreciated that proper spacing between the design elements 24 of side -by-side wall panels 10 is maintained by the third and fourth portions 39 and 41 of the continuous abutment 36 and the second margin 54 as illustrated at the left side of wall panel 10 in Figure 3. Following installation of all the wall panels 10, the mortar bed area 26 is grouted between the design elements 24 in order to provide the desired finished masonry appearance.

Reference is now made to Figures 7-9 illustrating an alternative embodiment of a backing panel 12' of the present invention. The backing panel 12' illustrated in Figures 7-9 is identical to the backing panel 12 illustrated in Figures 1-6 except in one respect. Specifically, the locating tabs 48' are shaped in the form of hooks. The other structural features of the backing panel 12', corresponding with the backing panel 12, are identified with the same reference numerals.

During the installation of a wall panel 10, including the backing panel 12, over the top of another such panel, the locating tabs or hooks 48' are inserted in the cooperating locating slots 46 of a previously mounted wall panel 10'. Once the locating hooks 48' are fully inserted in the locating slots 46 the new wall panel 10 is shifted laterally in the direction of arrow A (see Figure 9) so as to engage the hook with the abutment 36 of the underlying panel 10' and thereby securely interlock the two wall panels together.

In summary, numerous benefits result from employing the concepts of the present invention. A quick and efficient method of installing cast veneer wall panels is created. The method includes the steps of (a) fastening a first cast veneer wall panel to a support structure, (b) aligning cooperating tabs and slots provided on the first cast veneer wall panel and a second cast veneer wall panel, (c) engaging the tabs in the slots and (d) fastening the second wall panel to the support structure. Specifically, the method effectively reduces the number of fasteners required to secure the cast veneer wall panels to a support structure such as a building and conveniently aligns the panels for installation. These benefits are accomplished by providing the wall panels with cooperating locating tabs and slots that are engaged during wall panel installation. The foregoing description of the preferred embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. For example, Figure 10 illustrates a backing panel 12 including a series of spaced ribs 200 on the rear face of the mounting flange 44. The ribs 200 are provided in place of the spaced dimples 50. Typically, the ribs 200 are between about 0.05" and about 0.75" tall, between about 0.03" and about 0.5" wide and are spaced on centers of between about 0.25" and about 2.0". In one possible embodiment the ribs are 0.1" wide, 0.125" tall and are spaced on 0.58" centers. Like the dimples 50, the ribs 200 function to maintain an air gap between the panel 10 and the sheeting of the building framework for drainage and ventilation. The ribs 200 also function to strengthen the mounting flange 44 so that it will better hold a nail. Still further, cooperating locating tabs and slots could be provided at the opposite ends/sides of the panels 12 if desired. The optional structures could be similar to the locating tabs 48 and slots 46 provided along the top and bottom of the wall panel 12 (for example, a tab at the right end of the panel shown in Fig. 8) to provide further interlock of adjacent panels.

The embodiments were chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled. The drawings and preferred embodiments do not and are not intended to limit the ordinary meaning of the claims in their fair and broad interpretation in any way.
