DETAILED DESCRIPTION
[0063]
[0064] The standing seams 20 may at least generally proceed in the direction of or along the slope or pitch of the roofing surface 12 (e.g., the pitch of the length dimension of the standing seams 20 may match the pitch of the corresponding portion of the overall roofing surface 12). Each panel 18 includes at least one base section 22 that is at least generally flat or planar and that is disposed between each adjacent pair of standing seams 20 on the roofing surface 12. Each panel 18 could include one or more crests, minor ribs, intermediate ribs, partial ribs, striations, fluting, or flutes between its corresponding pair of standing seams 20 so as to provide multiple base sections 22 on each panel 18 (not shown).
[0065] The panels 18 may be of any appropriate configuration so to allow them to be interconnected or nested in a manner that defines a standing seam 20, and the standing seams 20 may be disposed in any appropriate orientation relative to the base sections 22 of the panels 18 that define the standing seam 20. Generally, each standing seam 20 is a protrusion of some sort that is defined at least in part by an adjacent pair of metal panels 18. For instance, the standing seams 20 may be characterized as at least initially extending orthogonally (e.g., perpendicularly) relative to the base sections 22 of the corresponding panels 18 (or relative to a pitch of the corresponding portion of the roofing surface 12). The illustrated standing seams 20 may be characterized as having a vertical end section, or as being of a vertical standing seam configuration. However, the end sections of the various standing seams 20 could also have portions that are horizontally disposed (e.g., at least generally parallel with the base sections 22 of the corresponding panels 18; at least generally parallel to a pitch of the corresponding portion of the roofing surface 12), or as being of a horizontal standing seam configuration.
[0066]
[0067] As noted, an edge portion (or longitudinal edge portion) of one panel may be interconnected with an edge portion (or longitudinal edge portion) of an adjacent panel to define a standing seam. Various types of standing seam configurations exist. One type of standing seam configuration has a larger space within the standing seam and may be referred to as a hollow seam rib configuration.
[0068]
[0069] Each hollow seam rib 86 of the panel assembly 80 may be characterized as having a first sidewall 88a and an oppositely disposed second sidewall 88b that are disposed in spaced relation (spaced in the lateral dimension 30). The first sidewall 88a includes an indentation 90a on an exterior of the seam rib 86, while the second sidewall 88b includes an indentation 90b on an exterior of the seam rib 86. The indentations 90a and 90b are disposed in opposing relation (e.g., disposed along a common axis that is orthogonal to the height of the hollow seam rib 86).
[0070] The seam rib 86 is of a hollow configuration, and includes an open space 96. A portion 92a of an internal surface of the seam rib 86 that is opposite of the indentation 90a (on the exterior of the seam rib 86) is spaced from a portion 92b of an opposing internal surface of the seam rib 86 that is opposite of the indentation 90b (on the exterior of the seam rib 86). In one embodiment, the portions 92a, 92b of the opposing internal surfaces of the seam rib 86 are separated by a distance D.sub.1 of at least about 0.35 inches (prior to being engaged by any seam fasteners not shown) and that is measured in the lateral dimension 30. In one embodiment, the portions 92a, 92b of the opposing internal surfaces of the seam rib 86 are separated by a distance D.sub.1 within a range of about 0.35 inches to about 0.75 inches. The open space 96 occupies the entire distance between the portions 92a, 92b of the opposing internal surfaces of the hollow seam rib 86. No other structure exists in this open space 96 throughout the entirety of the span between the portions 92a, 92b for the illustrated embodiment.
[0071] Exposed metal components of various types of equipment may be installed on a standing seam panel assembly of the types described herein and may become electrically energized, which in turn may electrically energize the standing seam panel assembly. In this regard, disclosed herein are various embodiments of standing seam panel assemblies that utilize an electrical bonding clip to establish an electrical path between adjacent pairs of panels that define a standing seam, and that may be used to electrically ground the standing seam panel assembly.
[0072] One embodiment of a standing seam panel assembly is illustrated in
[0073] The panels 82′ of the standing seam panel assembly 100 are interconnected to define a standing steam 102 that is of a configuration that is different from the hollow seam rib configuration depicted in
[0074] The right edge section 182b includes a sidewall 188b that extends upwardly when the corresponding panel 82′ is horizontally disposed (e.g., disposed orthogonal to the pitch of the corresponding roofing surface; extending away from a reference plane that contains the main body of the corresponding panel 82′), along with an end section 183b that extends downwardly when the corresponding panel 82′ is horizontally disposed (extending toward a reference plane that contains the main body of the corresponding panel 82′). The sidewall 188b and the end section 183b of the right edge section 182b are interconnected by an arcuate section, and with the end section 183b being disposed “outwardly” of the sidewall 188b in the lateral dimension 30. In the illustrated embodiment, the spacing between the sidewall 188b and its corresponding end section 183b is larger than the spacing between the sidewall 188a and its corresponding end section 183a.
[0075] Each panel 82′ further includes a first lateral edge or end 132 and a second lateral edge or end 136 that are spaced from one another, and each of which coincides with the lateral dimension 30. Typically the lateral dimension 30 will be that which coincides with a constant elevation when proceeding along a line in the lateral dimension 30 and when the panel assembly 100 is in an installed configuration to define a pitched roofing surface. In any case and as noted, a right edge section 182b of one panel 82′ is disposed over a left edge section 182a of an adjacent panel 82′ to define a standing seam 102 in the case of the panel assembly 100. At this time, the sidewall 188b of the right edge section 182b of one panel 82′ may be disposed in closely spaced relation (and/or actually in interfacing relation) with the sidewall 188a of the left edge section 182a of the adjacent panel 82′. An electrical bonding clip 104 may be installed on the standing seam 102 of the panel assembly 100, namely on corresponding portions of the sidewall 188b of one panel 82′ and the corresponding sidewall 188a of the adjacent panel 82′ that collectively define a standing seam 102. In the case of the standing seam panel assembly 100, the electrical bonding clip 104 may be characterized as being installed in a vertical orientation.
[0076] Details of each electrical bonding clip 104 used by the standing seam panel assembly 100 are presented in
[0077] The first clip member 112 and the second clip member 116 of the electrical bonding clip 104 may be biased at least generally toward one another (e.g., via the elasticity of the end section 124 of the clip 104), including to the extent where the first clip member 112 and second clip member 116 are in contact with one another prior to being installed on a standing seam 102 of the panel assembly 100 (although such is not required). In any case, the spacing between the first clip member 112 and the second clip member 116 increases as/when the electrical bonding clip 104 is being installed on a standing seam 102. This “expansion” of the electrical bonding clip 104 may be realized by a flexing or bending (e.g., an elastic deformation) of the electrical bonding clip 104, may be characterized as a relative deflection of the first clip member 112 and the second clip member 116 at least generally away from one another, or both. For instance, the end section 124 of the electrical bonding clip 104 may be characterized as a “living hinge” (e.g., an arcuately-shaped, elastically-deformable, pliable portion) that allows relative movement between and interconnects the first clip member 112 and the second clip member 116. As such, the first clip member 112 and the second clip member 116 of the electrical bonding clip 104 may be characterized as being relatively deflectable away from one another (e.g., the second clip member 116 of the electrical bonding clip 104 may at least generally move away from the first clip member 112 by an elastic deformation of an interconnecting portion of the electrical bonding clip 104, for instance the noted living hinge in the form of the end section 124; pivotal or pivotal-like motion at least generally about the end section 124).
[0078] The first clip member 112 and the second clip member 116 of the electrical bonding clip 104 may at least at some point in time be biased toward one another as noted, and again this biasing force may be provided by the end section 124 (e.g., an elastic configuration). During at least a portion of the relative movement of the first clip member 112 and the second clip member 116 away from one another, the amount of biasing force may progressively increase (e.g., by an elastic “flexing” of the corresponding end section 124). Although a biasing force could be exerted on one or more of the first clip member 112 and the second clip member 116 prior to being installed on a standing seam 102 (including when the clip members 112, 116 are in contact with one another), such may not be required.
[0079] Referring now to
[0080] The noted grounding projections 128 for the first surface 114 and second surface 118 of the electrical bonding clip 104 may be characterized as providing electrical continuity between standing seam panels that are engaged by the electrical bonding clip 104 (e.g., an electrical path may encompass a first panel 82′ engaged with one or more grounding projections 128 on the first surface 114 of the electrical bonding clip 104, the first surface 114 of the electrical bonding clip 104 being electrically connected to the second surface 118 of the electrical bonding clip 104 through the end section 124, and one or more grounding projections 128 of the second surface 118 of the electrical bonding clip 104 being engaged with a second panel 82′). This may be referred to as “bonding” or “electrically bonding” a pair of adjacent panels 82′. In any case, the noted electrical connection provided by the grounding projections 128 of the electrical bonding clip 104 may be used to electrically connect standing seam panels, which in turn may be used to provide an electrical path to ground an entire building surface of standing seam panels (or any portion thereof).
[0081] The electrical bonding clip 104 may be formed of any appropriate material or combination of materials to establish an electrical connection between a pair of panels 82′ that together define a standing seam 102 (e.g., a metal or a metal alloy, and including from an electrically conductive material). For example, the electrical bonding clip 104 may be formed entirely of stainless steel. Furthermore, the electrical bonding clip 104 may be fabricated in any appropriate manner. For instance, the electrical bonding clip 104 could be of a one-piece construction (e.g., being integrally formed from a piece of sheet metal).
[0082] In summary, an electrical bonding clip 104 of the panel assembly 100 may electrically engage overlapping portions of a first panel 82′ and a second panel 82′, namely at a standing seam 102 defined by the interconnection of these two panels 82′. In this regard, the electrical bonding clip 104 may be appropriate for installation on other standing seam configurations that are defined at least in part by overlapping portions from two adjacent panels, such as a double fold or double-folded standing seam configurations. The electrical bonding clip 104 provides what may be characterized as a “slide fit” for the pair of panels 82′ on which the clip 104 is installed. In this regard, the inlet section 120 of the electrical bonding clip 104 will be aligned with the adjacently disposed sidewalls 188a, 188b for the two panels 82′ at the lateral edges 132 of the two panels 82′ (another clip 104 could be installed on the same standing seam 102 at the oppositely disposed lateral edges 136 of the panels 82′ as desired/required). The electrical bonding clip 104 will then be advanced toward the standing seam 102 (e.g., at least generally in the direction of the opposing lateral edges 136 of the panels 82′) to position the first clip member 112 on one side of the standing seam 102 and to position the second clip member 116 on the other side of the standing seam 102. The electrical bonding clip 104 may be slid onto the standing seam 102 in the noted manner until the end section 124 of the electrical bonding clip 104 engages the lateral edges 132 of the two panels 82′ at the standing seam 102, although such may not be required in all instances.
[0083] In the embodiment shown in
[0084] When an electrical bonding clip 104 has been installed on a standing seam 102 in the noted manner, the two panels 82′ may be characterized as being “bonded” or “electrically bonded” via the electrical bonding clip 104. A series of panels 82′ that collectively define the panel assembly 100 may therefore be electrically connected by each associated electrical bonding clip 104, namely by installing at least one electrical bonding clip 104 on each adjacent pair of panels 82′ that collectively define a corresponding standing seam 102. This electrical path may be used to ground the entire panel assembly 100 (e.g., by running a grounding wire from one or more of the panels 82′ of the panel assembly 100 to ground, as each adjacent pair of standing seam panels 82′ in the panel assembly 100 should be electrically interconnected by at least one electrical bonding clip 104). The noted electrical path includes the left metal panel 82′ shown in
[0085]
[0086] In the illustrated embodiment, the electrical contact 128′ is at least generally triangularly-shaped, and in any case extends toward the opposing clip member 112, 116 at an angle. Other configurations may be appropriate. A free end section or point 128c of the electrical contact 128′ may be characterized as being disposed in the direction of the closed end section 124 of the electrical bonding clip 104, while the hinge 128b may be characterized as being disposed in the direction of the inlet 120. That is, the electrical contact 128′ may be characterized as extending from its hinge 128b at least generally in the direction of the closed end section 124. As noted, the electrical contact 128′ may also be characterized as extending from its hinge 128 associated with one of the clip members 112, 116, at least generally in the direction of the other of the clip members 112, 116.
[0087] Another embodiment of a standing seam panel assembly is illustrated in
[0088] The electrical bonding clips 104 used by the standing seam panel assembly 100 of
[0089] Referring now primarily to
[0090]
[0091] The electrical bonding clip 204 of the panel assembly 200 includes a first clip section 248 and a second clip section 252 that are spaced from one another in the lateral dimension 30. The first clip section 248 is positioned on one side of the standing seam 202 and engages only one of the two panels 82″ that defines this standing seam 202. In the view shown in
[0092] Additional details of the electrical bonding clip are shown in
[0093] The first clip member 212 for each of the first clip section 248 and second clip section 252 includes a first surface 214 that faces or projects toward the corresponding second clip member 216 (i.e., an interior surface for the corresponding clip section 248, 252) and that includes at least one of the above-noted grounding projections 128. The second clip member 216 for each of the first clip section 248 and the second clip section 252 includes a second surface 218 that faces or projects toward the corresponding first clip member 212. In the illustrated embodiment, the second surface 218 of the second clip member 216 for each clip section 248, 252 lacks any type of grounding projection (e.g., in the form of a smooth surface). The first clip member 212 for each of the first clip section 248 and the second clip section 252 is disposed on and engages an underside (or interior side) of the corresponding panel 82″, while the second clip member 216 for each of the first clip section 248 and the second clip section 252 is disposed on and engages a topside (or exterior side) of the corresponding panel 82″. As the second clip member 216 for each of the first clip section 248 and the second clip section 252 does not include any ground projections in the illustrated embodiment, installation of the electrical bonding clip 204 should not scratch the top or upper surface of the corresponding panels 82″ to any significant degree.
[0094] As illustrated in
[0095] In the case of the standing seam panel assembly 200 and as shown in
[0096] The clip sections 248, 252 for the electrical bonding clip 204 will typically be of a common configuration. The following discussion is equally applicable to both clip sections 248, 252 unless otherwise noted. The first clip member 212 and the corresponding second clip member 216 may be biased at least generally toward one another (e.g., via the elasticity of the corresponding closed end 224), including to the extent where the first clip member 212 and the corresponding second clip member 216 are in contact with one another prior to being installed on an adjacent pair of panels 82″ of the panel assembly 200 (although such is not required). In any case, the spacing between the first clip member 212 and the corresponding second clip member 216 increases as/when the electrical bonding clip 204 is installed on an adjacent pair of panels 82″ of the panel assembly 200. This “expansion” of the clip sections 248, 252 may be realized by a flexing or bending (e.g., an elastic deformation) of the clip sections 248, 252, may be characterized as a relative deflection of the first clip member 212 and the corresponding second clip member 216 at least generally away from one another, or both. For instance, the end section 224 for each of the clip sections 248, 252 may be characterized as a “living hinge” (e.g., an arcuately-shaped, elastically-deformable, pliable portion) that allows relative movement between and interconnects a first clip member 212 and a corresponding second clip member 216. As such, the first clip member 212 and the corresponding second clip member 216 may be characterized as being relatively deflectable away from one another (e.g., the second clip member 216 may at least generally move away (relatively) from the corresponding first clip member 212 by an elastic deformation of an interconnecting portion of the corresponding clip section 248, 252, for instance the noted living hinge in the form of the corresponding end section 224; pivotal or pivotal-like motion at least generally about the end section 224). The first clip member 212 and the corresponding second clip member 216 may at least at some point in time be biased toward one another as noted, and again this biasing force may be provided by the corresponding end section 224 disposed therebetween (e.g., an elastic configuration). During at least a portion of the relative movement of the first clip member 212 and the corresponding second clip member 216 away from one another, the amount of the biasing force may progressively increase (e.g., by an elastic “flexing” of the corresponding end section 224). Although a biasing force could be exerted on one or more of the first clip member 212 and the corresponding second clip member 216 prior to being installed on an adjacent pair of panels 82″ of the panel assembly 200 (including when the corresponding clip members 212, 216 are in contact with one another), such is not required.
[0097] Referring now to
[0098] The noted grounding projections 128 for the first surface 214 of the first clip member 212 for each of the clip sections 248, 252 of the electrical bonding clip 204 may be characterized as providing electrical continuity between a pair of standing seam panels that are engaged by the electrical bonding clip 204 (e.g., an electrical path may encompass one panel 82″ being engaged by one or more grounding projections 128 of the first clip member 212 for the first clip section 248 of the electrical bonding clip 204, by the first clip member 212 for the first clip section 248 of the electrical bonding clip 204 being electrically connected with the first clip member 212 for the second clip section 252 of the electrical bonding clip 204 by the intermediate portion 260 of the bottom plate 256, and the adjacent panel 82″ being engaged by one or more grounding projections 128 of the first clip member 212 for the second clip section 252 of the electrical bonding clip 204). Again, this may be referred to as “bonding” or “electrically bonding” an adjacent pair of panels 82″. In any case, the noted electrical connection provided by the grounding projections 128 of the electrical bonding clip 204 may be used to electrically connect adjacent pairs of standing seam panels, which in turn may be used to provide an electrical path to ground an entire building surface of standing seam panels (or any discrete portion thereof).
[0099] The electrical bonding clip 204 may be formed of any appropriate material or combination of materials to establish an electrical connection between a pair of panels 82″ that together define a standing seam 202 (e.g., a metal or a metal alloy, and including from an electrically conductive material). For example, the electrical bonding clip 204 may be formed entirely of stainless steel. Furthermore, the electrical bonding clip 204 may be fabricated in any appropriate manner. For instance, the electrical bonding clip 204 could be of a one-piece construction (e.g., being integrally formed from a piece of sheet metal).
[0100] In summary, an electrical bonding clip 204 electrically engages an adjacent pair of panels 82″ other than at the standing seam 202 defined by this adjacent pair of panels 82″ for the case of the panel assembly 200 of
[0101] When an electrical bonding clip 204 has been installed on an adjacent pair of panels 82″ in the above-noted manner, the two panels 82″ may be characterized as being “bonded” or “electrically bonded” via the electrical bonding clip 204. A series of panels 82″ that collectively define the panel assembly 200 may therefore be electrically connected by each associated electrical bonding clip 204, namely by installing at least one electrical bonding clip 204 on each adjacent pair of panels 82″ that collectively define a corresponding standing seam 202. This electrical path may be used to ground the entire panel assembly 200 (e.g., by running a grounding wire from one or more of the panels 82″ of the panel assembly 200 to ground, as each adjacent pair of standing seam panels 82″ in the panel assembly 200 should be electrically interconnected by at least one electrical bonding clip 204). An electrical path in accordance with the embodiment of
