DESCRIPTION OF THE EMBODIMENT

[0043] Referring to the drawings, FIGS. 1 and 2 show alternate embodiments of the pipe-on-pipe pipe support apparatus 10 of Applicant's invention. The apparatus 10 shown in FIG. 1 has a support base 11 having a corrugated upper surface or support top 12 with a series of ridges 16 and valleys 18 and a support bottom 14. Preferably, support base 11 is configured in a polygonal-shaped, such as a rectangle or square, although support base 11 may also be circular or oval in shape. Support base 11 of apparatus 10 has a height or thickness 20 sized to provide a desired pre-determined load bearing capacity for the apparatus 10. The support bottom 14 of base 11 of apparatus 10 has a pipe support area 24. Pipe support area 24 may be a curved support surface 15A with curved edges 17, as shown in FIG. 1, configured to conform to a curved underlying support surface such as a circular pipe support surface 32 as shown in FIG. 5.

[0044] Pipe support area 24 may also have a flat support surface 15B interposed between opposing support edges 17a positioned at intersecting angles as shown in FIG. 2. The opposing support edges 17a provide support surface 15B of support area 24 with beveled edge surfaces configured to conform to and intersect with a curved surface such as the circular pipe support surface 32 of underlying support structure 30 as shown in FIG. 6. Flanges or guides 22 adjacent the support edges 17 provide strength to the apparatus 10 and serve in placement and seating of the pipe support apparatus 10 upon its underlying support structure.

[0045] The flat support surface 15B with the opposing angled support edges 17a of support area 24 also provides an added advantage of allowing the pipe-on-pipe pipe support apparatus 10 shown in FIG. 2 to be used upon both an underlying support structure 30 having a curved upper surface 32 as shown in FIG. 6 or upon an underlying support structure 30 having a flat upper surface 33 such as the flat top of a beam flange or the flat top 31 of a column as shown in FIG. 9.

[0046] Support base 11 of the pipe support apparatus 10 will preferably be integrally molded from an isolating composite material with the thermal, load, and mechanical properties as may be required for suitable load bearing pipe supports. A suitable isolating composite material will preferably be comprised of fiber reinforced thermoplastic resin material. Suitable fiber reinforcement (not shown) for the fiber thermoplastic resin material for the support base 11 may include discrete fiber segments, including long or short fiber segments or a combination thereof, including metal or metal alloy fibers, glass fibers, synthetic fibers, natural fibers, and woven fiber fabric woven from such fiber materials, including woven fiber fabric impregnated with resin.

[0047] Other types of isolating composite material such as fiber reinforced concrete may be utilized also be utilized for the base 11 of pipe support apparatus 10. Suitable fiber reinforced concrete for the support base 11 will be a composite material consisting of mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fiber reinforcements. Suitable fiber reinforcement for the fiber reinforced concrete may be discrete fiber segments, including long or short fiber segments or a combination thereof, including metal or metal alloy fibers, glass fibers, synthetic fibers, natural fibers, and woven fiber fabric woven from such fiber materials, including woven fiber fabric impregnated with resin.

[0048] Depending upon the load to be supported, the anticipated environmental conditions, or other anticipated design considerations, the base 11 of pipe support apparatus 10 may also be cast, machined, or otherwise constructed of metal or metal alloys such as steel alloys, aluminum alloys, or cast iron. Preferably the apparatus 10 constructed of metal or metal alloys will be constructed of corrosion-resistant metal or metal alloys such as stainless steel or anodized aluminum or provided with a corrosion-resistant coating such as a galvanized coating, a polymer coating, or a bituminous coating as an isolating material.

[0049] The pipe support area 24 on the bottom 14 of the base 11 of pipe support apparatus 10 may be provided with a skid-resistant surface 26 as shown in FIG. 3 to increase the coefficient of friction of support area 24. When the pipe support apparatus 10 is in use, as shown in FIGS. 4, 5, and 6, the pipe support area 24 with the skid-resistant surface 26 is positioned upon the upper outer surface 32 of its underlying pipe support structure 30 to reduce slippage between the pipe support area 24 of pipe support apparatus 10 and the support surface 32. Preferably, the skid resistant surface 26 will provide the pipe support area 24 with a coefficient of friction in the range of 0.2μ to 0.8μ.

[0050] The skid-resistant surface 26 on support area 24 may be a skid-resistant surface coating such as a ceramic, paint, epoxy, or polymer coating, or combinations thereof having an anti-slip additive such as sand, silica, granulated stone, ceramics, combinations thereof, or other suitable anti-slip additives. It is thought that an anti-slip additive comprised of ceramic material will produce a coefficient of friction in the range ≥0.2μ to ≤0.8μ. The skid-resistant surface 26 of the support area 24 may also be provided by integrally molding the anti-slip additive into the surfaces 15A or 15B of a support area 24 of a desired base 11.

[0051] The pipe-on-pipe pipe support apparatus 10 may be used as shown in FIGS. 4, 5 and 6 during the initial construction of a piping system. For use, a support apparatus 10 of a desired predetermined configuration is installed by placing the support area 24 of the support bottom 14 of a support apparatus 10 to rest upon the curved upper surface 32 of a selected pipe support structure 30. Then, after the pipe support apparatus 10 is so installed, the piping P of the piping system is then positioned to rest upon and be supported by the ridges 16 of the support top 12 of the installed pipe support apparatus 10. Any rainwater or other liquids to which the piping P is exposed when so supported will then be collected in the valleys 18 on the support top 12, away from the piping P, thereby minimizing corrosion of the piping P. Guides 22 adjacent the edges 17 of the support area 24 provide strength to the apparatus 10 and serve to retain the pipe support apparatus 10 upon surface 32 of the underling pipe support structure 30.

[0052] The upgrade or replacement of an existing pipe support of a piping system with the pipe-on-pipe pipe support apparatus 10 described herein may typically be accomplished by the additional steps of lifting the segment of piping P where a pipe support replacement is desired, removing the existing pipe support from the underlying pipe support structure 30, removing any undesirable debris from the curved upper surface 32 of the underlying pipe support structure 30, if necessary, and then placing a pipe support apparatus 10 of a desired configuration upon the upper surface 32 of the underlying pipe support structure 30, and placing the segment of piping P of the piping system previously lifted upon the ridges 16 on the support top 12 of the replacement pipe support apparatus 10 as shown in FIGS. 4, 5, 6, 9 and 11. This replacement may be accomplished without any welding or attachment of the pipe support apparatus 10 to the underlying pipe support structure 30 or to the piping P.

[0053] In some situations, it may be necessary to use an attachment mechanism 34 to attach the pipe support apparatus 10 to piping P of a piping system or to the underlying pipe support structure 30. FIG. 7 shows attachment of the pipe support apparatus 10 to the supported piping P of a piping system by U-Bolts as the attachment mechanism 34. FIG. 8 shows the attachment of pipe support apparatus 10 a piping segment that serves as the underlying pipe support structure 30 by U-bolts as the attachment mechanism 34 for support of the piping P. Other suitable attachment mechanisms such as cables, hangers, straps, belts, or clamps may also be utilized as the attachment mechanism 34 to attach the pipe support apparatus 10 to the piping P or to the underlying pipe support structure 30.

[0054] FIG. 10 shows another alternate embodiment of the pipe-on-pipe pipe support apparatus 10 of Applicant's invention. The apparatus 10 shown in FIG. 10 has a support base 11, a corrugated support top 12 with a series of ridges 16 and valleys 18, a support bottom 14 with a pipe support area 24, and a height or thickness 20. However, in the embodiment of FIG. 10, the pipe support area 24 on bottom 14 of apparatus 10 is comprised of intersecting angled support edges 17b that create a beveled V-shaped support surface 15C with adjacent flanges or guides 22. The beveled V-shaped support surface 15C also allows the embodiment of apparatus 10 as depicted FIG. 10 allows the support edges 17 to be positioned upon a curved support surface 32 of an underlying support structure such as a piping segment as shown in FIG. 11. If desired, the pipe support area 24 may also have a skid-resistant surface 26 as previously described and shown in FIG. 3.

[0055] It will be evident that various other changes may be made in the form, construction and arrangement of the parts and steps of the apparatus and method described herein without departing from the spirit, scope, and material advantages of the invention. It is also thought that the method and apparatus presented herein will be understood from the foregoing description and that the forms and steps described herein are intended to be merely exemplary embodiments of the invention.
