Abstract
There is provided a pole or tower structure for supporting electric power supply cables wherein the structure has a generally rectangular configuration having four faces, the structure comprising a first ladder assembly having a pair of longitudinally extending members with generally parallel battens welded thereto interconnecting the members, a second ladder structure also having a plurality of battens interconnecting two longitudinally extending members, and each of the ladder structures being interconnected by braces mechanically attached to adjacent longitudinally extending members, all of the faces preferably having a generally tapered configuration from the bottom to the top. The structure can be easily engineered to replace wood poles presently used and allows for a relatively inexpensive structure providing ease of assembly at the site.
Description
The present invention relates to a tower or pole and more particularly, to a tower or pole suitable for supporting electric power supply cables and the like.
The use of poles for supporting electric power supply cables for power distribution and/or other cables to residences and light industry is well known. Generally, such poles have tended to be formed of wood for economic reasons. For shipping and ease of maneuver, wood poles have several advantages; however, wood poles also suffer from the disadvantage that they cannot be engineered to provide specific strength characteristics since this is inherent in the nature of the material.
It is an object of the present invention to provide a pole suitable for supporting electric power supply cables, and which pole can be engineered to provide desired structural characteristics.
It is a further object of the present invention to provide a pole suitable for electric power supply cables and which pole can be shipped in a knocked-down condition to the site and then assembled.
According to one aspect of the present invention, there is provided a pole or tower structure suitable for supporting electric power supply cables, the pole structure comprising four substantially vertically extending members, the vertically extending members being arranged in a rectangular configuration to provide four faces, a first pair of the substantially vertically extending members having extending therebetween a plurality of generally parallel battens, the battens being substantially perpendicular to the longitudinally extending members, a second pair of the substantially vertically extending members also being secured together by a plurality of generally parallel battens and which battens are the battens being welded to the vertically extending members, and a plurality of diagonally extending braces extending between adjacent members which are not secured together by the battens.
According to a further aspect of the present invention, there is provided a tower structure suitable for supporting electric power supply cables, the tower structure having a generally rectangular cross sectional configuration, the structure comprising a first ladder structure comprising a pair of longitudinally extending members and a plurality of generally parallel battens interconnecting the longitudinally extending members, each of the battens being substantially perpendicular to the longitudinally extending members, a second ladder structure comprising a pair of longitudinally extending members having a plurality of generally parallel battens interconnecting the longitudinally extending members, the battens being substantially perpendicular to the longitudinally extending members, the battens being welded to the longitudinally extending members, and a plurality of diagonally extending braces extending between adjacent longitudinally extending members not interconnected by said battens, the braces being connected to the longitudinally extending members by mechanical fastening means, and the tower having a generally inwardly tapered configuration on all faces thereof from its bottom to a top.
In greater detail, although the generally longitudinally extending members may have different configurations such as rectangular, circular, etc., a conventional preferred arrangement is the use of conventional angle irons - i.e. a piece of material having a pair of mutually perpendicular flanges. Suitable material for forming the angles would be various steel alloys.
A preferred arrangement is one in which a first ladder structure is formed by joining together a pair of the longitudinally extending angle irons by a plurality of substantially parallel battens which are welded to one of the flanges of the angle irons. The battens are preferably welded to a free marginal edge of the flange to thereby form a flat exterior surface.
A preferred arrangement is one in which the longitudinally extending members are angled inwardly so as to provide a slightly overall uniformly inwardly tapered and/or parallel configuration from the bottom to the top.
The amount of taper will vary depending upon the length of the structure, but generally a taper of between 1 and 15 is desired. A non tapered configuration can also be employed.
A second ladder structure is formed in a similar manner to the first ladder structure.
For shipping purposes, the assembled ladders having the desired length may then be shipped to the site where they are to be installed. At this point, the final assembly of the structure is carried out. To this end, the first and second ladder structures are secured together by diagonal bracing which extends between adjacent longitudinally extending members as will be described in the preferred embodiments.
The diagonal bracing may be any suitable type of member and is secured to the angles by suitable mechanical means - i.e. nuts and bolts. The assembled tower can then be erected and held in place by suitable means - i.e. either free standing or by the use of guy wires, etc.
The above type of tower structure provides substantial advantages. The combination of the welded ladder sub-assemblies and mechanically fastened bracing provides for a structure which has less surface area to thereby provide less wind resistance. This is also useful in period of inclement weather such as freezing rain and the like since there is less surface for the freezing rain to accumulate on.
The structure is also advantageous in that it uses a minimum of material for the strength achieved. The weight and ease of assembly also are positive factors.
21~gO31 The use of the battens makes it easier to climb with ladders - i.e. the battens provide a suitable place for a ladder rest.
The structure can be used as a single member or may be used in combinations as is known in the art.
Having thus generally described the invention, reference will be made to the accompanying drawings illustrating an embodiment thereof, in which:
Figure 1 is a perspective view of a tower structure according to the present invention;
Figure 2 is a cross sectional view taken along the lines 2-2 of Figure 1;
Figure 3 is a partial side elevational view as seen from the right hand side of Figure 2;
Figure 4 is a partial side elevational view as seen from the top and bottom of Figure 2; and Figures 5 to ~ are schematic views of different arrangements using the tower structure of the present invention.
Referring to the drawings in greater detail and by reference characters thereto, there is illustrated a tower structure according to the present invention and which structure is generally designated by reference numeral lO.
Tower structure lO is of a generally rectangular cross sectional configuration and has angle irons 12, 18, 24 and 30 at its corners. Angle iron 12 is formed to have 2154~31 mutually perpendicular flanges 14 and 16. Similarly, angle iron 18 has mutually perpendicular flanges 20 and 22; angle iron 24 being comprised of flanges 26, 28 and angle 30 of flanges 32, 34.
Interconnecting flanges 14 and 20 are a plurality of battens 36. As may best be seen in Figure 2, battens 36 extend between the free end of flanges 14 and 20 and are secured thereto by means of a weld 38 and 40 respectively.
On the other side, flanges 26 and 32 are connected between their free marginal edge by battens 42 which are secured thereto by means of welds 44 and 46 respectively.
Extending between flanges 22 and 28 are a plurality of diagonally extending braces 48. Braces 48 are secured to flanges 16 and 22 by means of a nut and bolt assembly adapted to pass through apertures 52 provided in flanges 22 and 28.
Similarly, apertures (not shown) are provided in flanges 16 and 34 permitting flanges 16 and 34 to be interconnected by means of braces 50.
It will be noted that braces 48, 50 are designed to be incrementally shorter from the bottom of the structure to the top. This provides an inwardly sloped or tapering structure to a pair of sides while the sides having battens 36 and 42 are straight.
As shown in Figure 5, tower structure 10 may be used as a self-supporting type of structure and suitably secured to the ground through cement or other means.
In Figure 6, tower structure 10 uses a guy wire 56 or additional security and support.
In Figure 7, a pair of tower structures 10 are employed with a pair of diagonal braces 58 and 60 extending therebetween and a horizontal arm 62 for supporting the electric power supply cables.
In Figure 8, a single tower structure 10 is employed on top of which is mounted standard structural steel framing generally designated by reference numeral 64 along with guy wires 66 and 68.
It will be understood that the above described embodiment is for purposes of illustration only and that changes and modifications may be made thereto without departing from the spirit and scope of the invention.
