Definitions

  • the present invention relates to an improved structural pole construction, particularly, but not exclusively, for use in transmission lines.
  • the structural pole of the present invention is comprised of two upright metal channel members interconnected by diagonal structural bars extending serially across the channel members whereby the pole is resistant to eccentric loads.
  • CA-A-1,073,632 relating to a semi-lattice pole construction comprising opposed channel members interconnected by a plurality of cross-arm braces disposed on opposed sides of the channel members. It can be seen that such a structural pole requires many parts for its constructions, i.e., braces and bolts, and is time consuming to assemble.
  • GB-A-628 868 discloses a structural pole corresponding to the definition given in the preamble of Claim 1.
  • the main upright members are standard channels with a web and two flanges extending inwardly from a flat outer wall of the channels.
  • the present invention provides a structural pole comprising a pair of upright metal channel members having an elongated flat outer wall with inwardly extending tranverse structural flanges; said channel members being interconnected in substantially parallel relationship, with their flanges extending inwardly, by a series of inner braces interconnected together and to said outer walls and spanning diagonally across said channel members and disposed in a predetermined pattern throughout the lengths of the channel members; each said diagonal brace being an elongated structural angle-iron bar having flat angulated connecting ends having a through bore therein and securable to said channel members by overlapping said connecting ends of adjacent diagonal braces, and a fastener interconnecting each said overlapping connecting ends with said flat outer wall of said channels, characterised in that said structural flanges of said pair of channel members have a right angle inner lip extending inwardly and parallel to said flat outer wall, and said elongated structural angle-iron bars have right angle walls of equal width, said inner braces in at least a lower portion of
  • the pole is comprised essentially of a pair of upright metal channel members 11 and 11' which are interconnected in substantially parallel relationship by a plurality of inwardly disposed braces 12 extending diagonally along the length of the pole.
  • the base 13 of the pole is secured in a concrete form 14 located beneath a ground surface 15.
  • the top end of the pole 10 supports a transmission line mast 16.
  • the pole can be used for a multitude of other applications and may be interconnected with like poles to form support columns.
  • the channel members 11 and 11' are formed steel channel members having an elongated flat outer wall 17 and transverse opposed structural flanges 18.
  • the ends of the structural flanges 18 are provided with a right angled inner lip 19 extending inwardly and parallel to the flat outer wall whereby to provide more structural rigidity to the channel members.
  • the top ones of the channel members need not have flanges with inner lips 19 as they are subjected to less loading than the bottom channel members where more structural strength is required.
  • the channel members 11 and 11' are interconnected in parallel relationship by a series of diagonally disposed inner braces 12 which are elongated structural bars, herein angle iron bars having a cross-wall 20 formed with right angle sections which are of equal width and form a right angle structure brace.
  • the ends of the bars are flattened to form angulated connecting ends 22.
  • the connecting ends are provided with one or two, herein one, through bore 23 which is centrally aligned with the apex 21 of the bar.
  • each bar 12 is overlapped with a connecting end 22 of an adjacent bar (see Figure 2) and interconnected together by a fastener 24 which extends through aligned bores 23 of overlapped interconnecting ends 22 and a bore 25 provided in the outer wall 17 of the channels 11 and 11', respectively.
  • a single bolt fastener secures opposed ends of diagonal braces 12 to the channels with the bars 12 spanning the structural channels 11 and 11' throughout the length of the pole. Therefore, any load on the poles will be transmitted to the connecting points (the bolt connection 24) disposed on opposed walls whereby the channels are not subjected to eccentric loads.
  • a pole is constructed by interconnecting two or more pairs of channel members 11 and 11' end-to-end by a telescopic overlap section, as illustrated at 27.
  • the telescopic connection simply consists in providing a top pole section which is provided with like channel members 28 and 28', but of smaller size whereby to slide fit inside a top portion of the channels 11 and 11' respectively.
  • a plurality of splice bolts 29 would then secure these overlapped ends together.
  • Transverse cross braces 30 may also interconnect the channels 11, 11' and 28 and 28' together and solidify the splice.
  • the braces 12 are disposed such that a brace 12' spans the splice region 27 to strengthen the joint.
  • next diagonal brace 12" extends diagonally across opposed sides of the channel members while the next brace 12" extends diagonally between the other common side of the channel members.
  • This pattern provides for a stronger pole section by providing improved torsional resistance and preventing the side wall 17 from bowing out.
  • an elongated reinforcing rib 31 may be formed in the outer wall 17 of the channel members 11 and 11' and located centrally thereof, whereby to strengthen the wall 17 and lower pole section.
  • the pattern of these braces 12 can vary along the length of the pole dependent of the number of pairs of channel members being interconnected end to end.
  • the upper sections of the pole may have all their braces interconnected along a common central plane 26 as illustrated in Figure 3A as this facilitates installation.
  • the flanges 18 of the top channel members need not have a right angle inner lip 19 as shown in Figure 3B, as this section of the pole is subjected to less stress.
  • Some of the channel members 11 and 11' may also be provided with interspaced series of three holes 32 (see Figure 4) for attachment of the braces 12 in any desired abovementioned configuration.
  • the space holes 32 may be used to attach auxiliary equipment to the pole, such as guy wires, transformers, platforms (not shown), etc.
  • poles can be strengthed by the configuration of the serially interconnected braces which span the opposed channel members internally of the pole.
  • a still further advantage of this pole is that it is of more pleasing aesthetic design which is an advantage when a pole line extends through a residential community.
