TECHNICAL FIELD
This document pertains generally, but not by way of limitation, to platforms such as for utility poles such as monopoles, such as for raised antenna implementations in the field.
BACKGROUND
Utility and communication poles can include monopoles that can be used to raise or support lights, communications equipment, or other devices above the surface to which they are mounted. Platforms can be mounted to the monopole, such as at an extended distance above the earth or other surface from which the monopole extends. A human worker may climb the monopole and stand on the platform. Equipment may be mounted to the platform.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
FIG. 1 is an example of a platform that can be mounted to a utility or communications monopole.
FIG. 2 is an example of such a platform that can include vertical corner pedestals to provide increased stability, and can accommodate variations in vertical locations of the mounting pipes extending between a triangular or other arrangement of lower rails and a similar triangular or other arrangement of upper rails.
DETAILED DESCRIPTION
The present inventor has recognized, among other things, that structural integrity and the ability to accommodate variations in equipment sizes and mounting orientations to platforms can be important considerations.
FIG. 1 shows an example of a platform assembly 100 such as can be mounted onto a utility monopole, such as via a bracket 102. In an example, the bracket 102 can include a collar, such as a tri-collar bracket assembly that can accommodate a 10 inch through 40 inch monopole extending there through. Any number (e.g., three) of platforms 104 can be mounted to the bracket 102, such as on arms 106 extending laterally and radially therefrom. The platforms 104 can respectively include a trapezoidal or other frame extending from the arms. A metal mesh or other flooring material can be welded or otherwise affixed to the frames of the platforms 104, such as to provide a floor or step that a human utility or communications worker can stand upon, such as while the communications worker is mounting communications or other equipment directly or indirectly to the monopole.
Adjacent platforms 104 can be connected and braced by square tube or other lower rails 108, which can be bolted to peripheral edges of the adjacent platforms, such as to form a triangle, such as shown in FIG. 1. A similar triangular arrangement of upper rails 110 can be located above corresponding lower rails 108. Vertical mounting pipes 112 can extend between the lower rails 108 and the corresponding upper rails 110, such as by being bolted thereto, such as using U-bolts, or otherwise. The vertical mounting pipes 112 can support the upper rails 110 above the corresponding lower rails 108. Corner connection plates 114 can be bolted between adjacent upper rails 110, such as using U-bolts or otherwise, such as to secure adjacent upper rails 110 to each other in their triangular arrangement.
One problem with the approach shown in FIG. 1 is that the vertical mounting pipes 112 are generally longer than the spacing between the upper rails 110 and the lower rails 108 and, therefore, may not be mounted at a consistent height with respect to the upper rails 110, the lower rails 108, or both. In addition, in many instances it is advantageous to have the center of the vertical mounting pipes 112 raised above the center of the lower rails 108. Such variations in the moments imposed by loading creates variable stresses than must be accommodated, preferably by adding as little weight as possible and as few components as possible.
FIG. 2 shows an example of such additional components that can accomplish this objective. FIG. 2 shows an example of a platform assembly 200, similar to the platform assembly 100 shown in FIG. 1, but including a number (e.g., one or more of three) of vertical pedestals that can be bolted to and extend between respective platforms 104 and corresponding corner connection plates 114 that are located above such respective platforms 104. This can provide increased stability to the triangular arrangement of upper rails 110, which, in turn, can allow the platform assembly 200 to bear more equipment or other weight, including when there is variability in the height or vertical location of one or more of the individual vertical pipes 112. The arrangement shown in FIG. 2 can be implemented in a new instantiation of a platform assembly 200, or can be implemented as a retrofit of a platform assembly similar to that shown in FIG. 1, or the like.
