This invention generally relates to a wall panel system.
Exterior, and interior, wall panel systems provide an efficient and cost-effective way to create or improve the appearance of a building. Often used in commercial or industrial building construction, wall panel systems give builders and owners a wide variety of exterior finishes to choose from.
A common problem for many conventional wall panel applications, especially those made from metal, is that, when fixed in some type of channel, the metal panel tend to expand and contract due to normal variations in temperature. Often, this results in a condition known as “oil canning”, which is the buckled or wavy appearance seen in some wall panels.
Embodiments of the present invention address the aforementioned problem and represent an improvement to the state of the art in the construction of both exterior and interior wall panel systems. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.
In one aspect, embodiments of the invention provide wall panel system that includes a plurality of wall panels, and one or more hat channels each configured to be attached to a supporting wall and each configured to be attached to the one or more of the plurality of wall panels. The one or more hat channels maintains a predetermined distance between the supporting wall and the plurality of wall panels. One or more keeper members are each configured to be attached to one of the one or more hat channels. When the wall panel system is assembled, each keeper member at least partially supports the weight of the one or more wall panels
In a particular embodiment, the one or more hat channels are one or more vertical hat channels that extend vertically so as to maintain a horizontal distance between horizontally-adjacent wall panels. In some embodiments, the one or more vertical hat channels maintain a uniform horizontal distance between horizontally-adjacent wall panels.
In other embodiments, the one or more hat channels are one or more horizontal hat channels that extend horizontally so as to maintain a vertical distance between vertically-stacked wall panels. In some embodiments, the one or more horizontal hat channels maintain a uniform vertical distance between vertically-stacked wall panels.
In certain embodiments, the one of the one or more keeper members includes an upper portion and a U-shaped lower portion configured to receive a downward-extending flange from at least one of the plurality of wall panels. At least one of the one or more keeper members may include one or more openings in the U-shaped portion to allow for the escape of moisture. Furthermore, the U-shaped lower portion may be positioned in front of a top flange for one of the plurality of wall panels directly below the at least one of the one or more keeper members.
In a further embodiment, a top-most wall panel includes a hanging flange on a top edge of the top-most wall panel, the hanging flange extending rearward from the top-most wall panel then downward. Embodiments of the invention include a top rail with a U-shaped portion configured to receive the downward-extending portion of the hanging flange. Moreover, the wall panel may be made from aluminum, and the thickness of the aluminum may range from 0.050 of an inch to 0.063 of an inch. At least one of the one or more keeper members and at least one of the one or more hat channels may also be made from aluminum, and the thickness of the aluminum may range from 0.050 of an inch to 0.063 of an inch.
Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
Embodiments of the invention described herein include a wall panel system that could be used on the interior or exterior of commercial and industrial buildings. As will be shown below, embodiments of the invention show a wall panel system composed of stackable horizontal wall panels, and a wall panel system composed of stackable vertical wall panels. In both systems, the wall panels are tied together using devices referred to below as keeper members, and hat channels. The hat channels may be horizontal or vertical and the wall panels and keeper members may be mounted onto the various hat channels.
The wall panels 102 may be made from a variety of suitable materials. In specific embodiments of the invention, the wall panels 102 are made from aluminum. In a particular embodiment of the invention, aluminum panels 102 are constructed using aluminum of either 0.050″ or 0.063″ thickness. However, it is understood that the wall panels 102 and channel members may both be made of aluminum, or some other similarly suitable material, whose thickness is less than 0.050″ or greater than 0.063″.
In specific embodiments and as shown in
In the embodiment shown, the wall panel system 100 is supported by the sill 112 at the base of the wall. The sill 112 may also support one or vertical reveals 114, attached to the sill 112 at the floor level. The sill 112 may also include one or more horizontal support channels to support and separate the bottom-most wall panels 102 from the floor. As shown in
A horizontal reveal 116 runs horizontally (e.g., between vertical reveals 114), and provides vertical separation between vertically-stacked wall panels 102. As shown in
In this way, the keeper member 124 positioned below the wall panel 102 supports the weight of the wall panel 102. With respect to the keeper member 124 positioned above the wall panel 102, the top flange 110 of the wall panel 102 extends upward behind the channel portion 128 of the keeper member 124 positioned above to keep the wall panel upright and against the wall.
In particular embodiments, the upper panel 126 of the keeper member 124 may include long relatively straight portion which can be attached to a hat channel member described in more detail below. The channel portion 128 of the keeper member 124 may be substantially U-shaped and extend downward from the upper panel 126. The U-shaped channel portion 128 is designed to securely hold the downward-extending lower flange 130 of the wall panel 102 such that the wall panel is not prohibited from expanding or contracting due to temperature variation, but is nevertheless securely held in place. Further, the keeper member 124 helps maintain a uniform vertical spacing between vertically-stacked wall panels 102. However, alternate embodiments allow for keeper members 124 designed to maintain varying or non-uniform spacing between wall panels 102.
One of the advantages of the wall panel system 100 described herein is the wall panel's ability to “free-float” within the keeper channels 124. Because embodiments of the present invention provide for a “free-floating panel” within the confines of the keeper channels 124, the wall panel system is not susceptible to oil canning, as the system 100 is not significantly affected by the expansions and contractions of individual wall panels 102 due to normal temperature variation.
The top rail 120 is similar to the aforementioned keeper members 124, but typically, though not necessarily, has a different shape. In a particular embodiment, the top rail 120 has a straight portion for attachment to the supporting wall, and an angled portion which connects that straight portion to the U-shaped portion that helps support the weight of the top-most wall panel 102.
Like the wall panels 102, in particular embodiments, the vertical and horizontal hat channel members 134, 144 are constructed of aluminum of either 0.050″ or 0.063″ thickness, or some thickness in between. The wall panel system 100 with the above-described vertical reveals 114 and the vertical and horizontal hat channels 134, 144 in combination with the keeper members 124, allows for the wall panels 102 to be easily and quickly assembled one upon another, and side-by-side. This allows for a much faster, and less expensive, installation process.
The wall panels 102 are vertically stackable and spaced horizontally through the use of the aforementioned vertical and horizontal hat channels 134, 144 which attach to the supporting wall and maintain uniform separation between adjacent wall panels 102 and between the wall panels 102 and the supporting wall. It is also envisioned that, in some embodiments, the vertical and horizontal hat channels 134, 144 may be designed to maintain a varying, or non-uniform, separation between the wall panels and the supporting wall.
Vertical hat channels 134 are typically used in wall panel systems 131 comprised of horizontal wall panels 132, while horizontal hat channels 144 are typically used in wall panel systems 141 comprised of vertical wall panels 142. In both types of wall channels, vertical stacking is facilitated by the use of the aforementioned keeper members 124 which are attached to the vertical and horizontal hat channels 134, 144.
Certain embodiments of the wall panel system may be used in conjunction with a rain screen type system. A rain screen system is not by design a waterproof system, rather it is water-inhibiting system which relies on a waterproof substrate for water-tight integrity.
