Abstract
Description
- The present invention generally relates to a clamp device for a cable tray assembly.
- Cable tray is used by industry to support electrical cable. A length or section of cable tray comprises a pair of side rails connected by cable-supporting rungs extending between the rails at intervals along the tray. The side rails are typically made from sheet metal of a particular gauge (i.e., thickness). Typically, supports, such as trapeze supports, are installed at regular intervals of the cable tray run.
- Cable trays are rated according to their load-bearing capacities. For example, the International Electrotechnical Commission (IEC) has a standard IEC 61537 to determine the load-bearing capacity of a cable tray. In general, the rated load-bearing capacity of a cable tray is the load on the cable tray that deflects the cable tray 1/100th of the span length using one of a number of predefined test methods, such as type II test. For example, using a cable tray having a span of 6 m during the type II test, the load on the cable tray that causes the cable tray to deflect 60 mm ( 1/100th of 6 m) is the rated load-bearing capacity of that specific tray.
- One way to increase load-bearing capacity for particular cable tray is to increase the thickness or gauge of the rails. However, this approach increases both the weight and the cost of the cable tray.
- It is an object of the present disclosure to increase a load-bearing capacity of a cable tray without increasing the thickness or gauge of the rails. This object is accomplished through the use of a clamp device including a clamping plate having a first side portion that is sized and shaped for reception into a channel defined by a bottom channel portion of one of the rails of the cable tray. The clamping plate has a second side portion configured for fastening to a cable tray support such that the bottom channel portion of the rail is clamped between the clamping plate and the cable tray support. The use of the clamp device increases the load-bearing capacity of the cable tray over an identical cable tray that does not include the clamping plate.

Referring toFIGS. 1 and 6 , the laddercable tray assembly 10 includes two parallel rails, each generally indicated by 24, extending lengthwise of the cable tray assembly (a centerline CL extending lengthwise of the cable tray assembly is shown inFIG. 1 ) and forming sides of the cable tray assembly. A plurality of cable-supportingrungs 26 extend between therails 24 at intervals spaced lengthwise of the rails. Together, therails 24 and therungs 26 form a cable tray of the assembly. Eachrail 24 comprises a generallyvertical web 30, anupper crown 32 at the upper end of the web, and a bottom channel section, generally indicated at 38, at a lower end of the web. Theupper crown 32 defines inboard and outboard flanges, 32A, 32B, respectively. Thebottom channel section 38 has aheel portion 42 projecting laterally outward (i.e., in an outboard direction relative to the rail) from theweb 30 and a generallyhorizontal toe portion 46 projecting laterally inward (i.e., in an inboard direction relative to the rail) from the heel portion to a location inboard or inward of theweb 30. The heel andtoe portions channel 50 extending lengthwise of therail 24 and facing inboard or toward the centerline CL. Theweb 30 defines a bead 52 (or indentation) extending in the inboard direction lengthwise of therail 24. A vertical gap between thebead 52 and thetoe portion 46 receive ends of therungs 26. Therungs 26 may be secured (e.g., by welding) to inboard portions of therails 24. In one embodiment,rails 24 are formed from 1.2 mm sheet metal (e.g., 304 or 316 stainless steel). Therails 24 may be formed from sheet metal of other thicknesses. - Referring to
FIG. 6 , the illustratedcable tray assembly 10 further includes a first and second clamp devices, generally indicated at 60, 62, respectively, for clamping thebottom channel sections 38 of therails 24 to a cable tray support 66 (e.g., a strut, a trapeze support, etc.) opposing lower surfaces of the channel sections. It is understood that the use of two illustratedclamp devices FIG. 5 , theclamp devices rail 24 and an opposing clamp device of the same type on the other rail. - Referring to
FIGS. 6 and 7 , thefirst clamp device 60 includes aclamping plate 70 having afirst side portion 70A sized and shaped for reception in thechannel 50 and asecond side portion 70B extending toward the centerline between therails 24, inward of thebottom channel section 38. As shown inFIGS. 1, 2, 5, 6 and 7 , thesecond side portion 70B defines a fastener opening 72 (e.g., a slot-shaped opening extending lengthwise of the rails 24) through which a fastener 74 (e.g., a bolt) extends for securing the clamping plate to thecable tray support 66. With thefirst side portion 70A received in thechannel 50 and thefastener 74 extending through the fastener opening 70B and fastened to the cable tray support 66 (FIG. 6 ), thebottom channel section 38 of thecorresponding rail 24 is clamped between theclamping plate 70 and the cable tray support. It is understood that theclamping plate 70 may include more than one fastener opening 72 and more than onefastener 74. - The
clamping plate 70 may have a uniform thickness T, as shown inFIG. 6 , measuring from about 3.5 mm to about 4.2 mm, such as about 4.0 mm, so that thefirst side portion 70A fits snugly, and/or has an interference fit, within thechannel 50. For example, as shown inFIG. 9 , a clearance C between anupper surface 70 a of theclamping plate 70 and theinner surface 50 a of the upper wall of thechannel 50 may be between about 0.01 mm and about 1.70 mm. Alternatively, theclamping plate 70 may have a non-uniform thickness (not shown), with thefirst side portion 70A having a thickness from about 3.5 mm to about 4.2 mm, such as about 4.0 mm, and/or a clearance C between theupper surface 70 a of theclamping plate 70 and theinner surface 50 a of the upper wall of thechannel 50 between about 0.01 mm and about 1.70 mm. As shown inFIG. 7 , theclamping plate 70 may have a longitudinal dimension L (e.g., a length), which extends lengthwise of thecable tray assembly 10, measuring from about 65 mm to about 75 mm, such as about 70 mm, and a transverse dimension W (e.g., a width) measuring from about 60 mm to about 65 mm, such as about 62 mm. In the illustrated embodiment, when theclamping plate 70 is secured to thesupport 26, theterminal end 70 c of the clamping plate is at or extends past the mid-point of a depth D (FIG. 9 ) of thechannel 50, and in one example, the terminal end is at or extends past ¾ of the depth of the channel. Theclamping plate 70 may be formed from a generally rigid material, such as metal (e.g., 304 or 316 stainless steel, or other metal). - In one embodiment of a method of use, a plurality of
first clamp devices 60 clamp bothrails 24 of thecable tray assembly 10 to thecable tray support 66 at uniform intervals lengthwise of the cable tray assembly. For example, thefirst clamp devices 60 may be spaced at uniform intervals measuring about 3 m to 6 m lengthwise of thecorresponding rail 24. Thefirst clamp devices 60 may be spaced at other uniform intervals or at non-uniform intervals lengthwise of therail 24. In one embodiment, thefirst clamp devices 60 may be spaced at intervals sufficient to increase the load-bearing capacity of thecable tray assembly 10 compared to an identical cable tray assembly that does not include the first clamp devices. Theclamp device 60 increases the load-bearing capacity of thecable tray assembly 10 in two ways: 1) theclamping plates 70, by virtue of the clamping plates being received in thechannel 50, inhibit crushing of the bottom channel section 38 (i.e., narrowing of the channel 50) when a load is applied to the cable tray assembly; and 2) the clamping plates, by virtue of the clamping plates being secured to thesupports 26, rigidify the rails to retain the heightwise axis H (FIG. 9 ) of the rails (e.g., vertical axes) at orthogonal or perpendicular angles relative to the plane S (FIG. 9 ) in which the supports 66 lie (e.g., a horizontal plane extending between the two rails). Moreover, theclamping plates 70 are retained in thechannels 50 and are inhibited from slipping out of the channels by virtue of the clamping plates being fastened to thesupports 66. - In one example, a
cable tray assembly 10 constructed according to the principles of the present disclosure included therails 24 of 316 stainless steel having a thickness of 1.2 mm, therungs 26 spaced apart at uniform intervals of about 300 mm, and thefirst clamp devices 60 spaced apart at uniform intervals of about 3 m. This cable tray assembly was rated to have a load-bearing capacity of 340 kg/m using IEC 61537 test type II. An identical cable tray assembly that did not include thefirst clamp devices 60 was rated to have a load-bearing capacity of 250 kg/m using IEC 61537 test type II. - Referring to
FIGS. 3, 4 and 6 , eachsecond clamp device 62 includes the clampingplate 70 of the first clamp device (or another clamping plate) and a web bracket (or gusset), generally indicated at 80, interconnecting therail web 30 to the clampingplate 70. The teachings set forth above with respect to thefirst clamping plate 70 of the first clamp device, including the dimensions of the clamping plate, the clearance C between the clamping plate and thechannel 50, and the depth at which the clamping plate is inserted into the channel, apply equally to the clamping plate of thesecond clamp device 62. As described above with respect to thefirst clamp device 60, the clampingplate 70 includes afirst side portion 70A received in thechannel 50 and afastener opening 72 in asecond side portion 70B inward of thetoe portion 46 of therail 24. As also shown inFIG. 8 , theweb bracket 80 includes a web-securement portion 80A, a clamping-plate-securement portion 80B, and anangled portion 80C extending between the web-securement portion and the clamping-plate-securement portion. The web-securement portion 80A defines at least one fastener opening 84 (e.g., two fastener openings) and is in face-to-face engagement with the inboard side of theweb 30 above thebead 52. Referring toFIGS. 3 and 4 , the web-securement portion 80A is secured to theweb 30 by at least one fastener 86 (e.g., two bolts) extending through thefastener openings 84 and at least one opening 87 (e.g., two openings) in the web that are at least partially aligned with respective fastener opening. The clamping-plate-securement portion 80B defines at least one fastener opening 88 (e.g., a slot-shaped opening extending lengthwise of the rail 24) and is in face-to-face engagement with the clampingplate 70 such that at least portions of thefastener openings fastener openings cable tray support 66. Theangled portion 80C of theweb bracket 80 may extends at an acute angle (e.g., from about 30-60 degrees, such as 45 degrees) relative to a vertical center plane Vp (FIG. 6 ) of thecable tray assembly 10. In the illustrated embodiment, theweb bracket 80 and the clampingplate 70 of thesecond clamp device 62 are formed separately and secured to one another by the fastener(s) 90. - Referring to
FIGS. 10 and 11 , in a second embodiment the second clamp, indicated generally at 162, is integrally formed as a single, one-piece component. For example, thesecond clamp 162 may be formed from a single sheet of metal, such as by stamping. In the illustrated embodiment, theclamp device 162 includes aclamping plate 170 and a web bracket (or gusset), generally indicated at 180, interconnecting therail web 30 to the clampingplate 70, as shown inFIG. 11 . The teachings set forth above with respect to thefirst clamping plate 70 of the first clamp device, including the dimensions of the clamping plate, the clearance C between the clamping plate and thechannel 50, and the depth at which the clamping plate is inserted into the channel, apply equally to the clamping plate of the second embodiment of thesecond clamp device 162. As described above with respect to thefirst clamp device 60, the clampingplate 170 includes afirst side portion 170A received in thechannel 50 and a fastener opening 172 in asecond side portion 170B inward of thetoe portion 46 of therail 24. As also shown inFIG. 10 , theweb bracket 180 includes a web-securement portion 180A and an angled portion orarms 180C extending between the web-securement portion and theclamping plate 170. The web-securement portion 180A defines at least one fastener opening 184 (e.g., two fastener openings) and is in face-to-face engagement with the inboard side of theweb 30 above thebead 52. The clampingplate 170 may have a uniform thickness T measuring from about 3.5 mm to about 4.2 mm, such as about 4.0 mm, so that thefirst side portion 170A fits snugly, and/or has an interference fit, within thechannel 50. For example, a clearance C between an upper surface 170 a of theclamping plate 170 and theinner surface 50 a of the upper wall of thechannel 50 may be between about 0.01 mm and about 1.70 mm. - Referring to
FIG. 11 , the web-securement portion 180A is secured to theweb 30 by at least one fastener 86 (e.g., two bolts) extending through thefastener openings 184 and at least one opening 87 (e.g., two openings) in the web that are at least partially aligned with respective fastener opening. The clampingplate 170 defines at least one fastener opening 188 (e.g., a slot-shaped opening extending lengthwise of the rail 24), as shown inFIG. 10 . At least one fastener 90 (e.g., a bolt) extends through thefastener opening 188 and is secured to thecable tray support 66. Theangled portion 180C of theweb bracket 180 may extends at an acute angle (e.g., from about 30-60 degrees, such as 45 degrees) relative to a vertical center plane Vp (FIG. 6 ) of thecable tray assembly 10. - In one embodiment of a method of use, a plurality of
second clamp devices 62, 162 (e.g., the first embodiment, the second embodiment, or a combination of the embodiments) clamp therails 24 to thecable tray support 66 at uniform intervals lengthwise of thecable tray assembly 10. For example, thesecond clamp devices rail 24. Thesecond clamp devices rail 24. In one embodiment, thesecond clamp devices cable tray assembly 10 compared to an identical cable tray assembly that does not include the first clamp devices. Thesecond clamp device cable tray assembly 10 in three ways: 1) theclamping plates channel 50, inhibit crushing or compression of the bottom channel portion 38 (i.e., narrowing of the channel 50) when a load is applied to the cable tray assembly; and 2) the clamping plates, by virtue of the clamping plates being secured to thesupports 26, rigidify the rails to retain the heightwise axis H (FIG. 9 ) of the rails (e.g., vertical axes) at orthogonal or perpendicular angles relative to the plane S (FIG. 9 ) in which thesupports 66 lie (e.g., a horizontal plane extending between the two rails); and 3) theweb bracket webs 30 of the rails. Moreover, the clampingplates channels 50 and are inhibited from slipping out of the channel by virtue of the clamping plates being secured to the supports. - In one example, a cable tray assembly constructed according to the principles of the present disclosure included the
