Abstract
A means and method for rigidly elevating a structure includes a base member securable in the ground and which has a portion extending above the ground. A pole section, having a bore inside a lower end, and an upper end, can be stacked upon the base means upwardly by slip fitting the pole section onto the base end and securing it in place. A flexible, easily transportable and durable system is thereby created for elevating structures.
Claims12
A method of rigidly suspending a plurality of pre-aimed light fixtures mounted on a cross arm in a substantially elevated position to concurrently elevate and precisely position the light fixtures so that manual aiming of the light fixtures from the elevated position is not needed, comprising the steps of:
- manufacturing a preformed concrete base and a tubular steel pole selected for appropriate sizes to suspend the cross arm and light fixtures to a desired elevation, the base having a tapered top portion upon which a mating tapered bottom portion of the pole is slip fit;
- excavating a hole in the ground which is wider in diameter than the base;
- positioning the base, capable of supporting the pole, cross arm and light fixtures, in the hole in a relatively plumb position, the tapered top portion of the base extending above ground level when the base is positioned in the hole, the top portion of the base being substantially closer to the ground than to the light fixtures once elevated;
- backfilling concrete into the hole around the base;
- plumbing the base during backfilling of the concrete;
- allowing the backfilled concrete to at least partially set;
- installing the tapered bottom portion of the pole onto the base with the cross arm and pre-aimed light fixtures attached by slip fitting the pole onto the base to a point that the pole has substantial vertical stability yet can be rotated;
- rotationally adjusting the pole on the base to precisely aim the cross arm and light fixtures relative to a target;
- and
- seating the pole on the base by further slip fitting so that the bottom end of the pole is above ground and the pole means is rigidly mounted to the base so that it can not be moved vertically or rotated by normal environmental forces.
A method of installing a light assembly-sports pole combination, the light assembly including a cross arm having known reference points upon which are mounted in predetermined orientations with respect to the known reference points of the cross arm a plurality of pre-aimed light fixtures, said method comprising:
- positioning a concrete base partially above ground and partially below ground in a plumb position and in a manner capable of withstanding substantial lateral forces, said base being adapted for mating relationship with a sports pole light assembly-combination;
- slip fitting a hollow end of the light assembly-sports pole combination in mating relationship over an above ground portion of the concrete base;
- aligning the light assembly by rotating the sports pole on said base to precisely orient the cross arm to a sporting field area and consequently precisely aim the light fixtures to the sports field area;
- and
- securing said pole onto said base in an aligned position so that manual aiming of the light fixtures, once elevated, is not necessary.
