This invention relates to construction equipment and methods.
More particularly, the present invention relates to methods and equipment for emplacing columns in a surface.
In the field of construction, emplacing columns for a structure, such parking shade structures, requires a great deal of labor. The columns must be properly positioned, a hole must be dug to receive the column, the column inserted into the hole and the hole backfilled. While backfilling, the column must remain properly positioned, and the backfill must be strong enough to support the column and structure of which it is a part. The time and effort needed to emplace columns is substantial, resulting in high costs for this kind of construction.
It would be highly advantageous, therefore, to remedy the foregoing and other deficiencies inherent in the prior art.
An object of the present invention is to provide apparatus and method for quickly and easily emplacing columns.
Briefly, to achieve the desired objects and advantages of the instant invention, provided is a sonic drilling apparatus with adapter for emplacing columns. Included is a sonic drilling apparatus having a fitting. An adapter is coupled to the fitting. The adapter includes a base having a socket extending upwardly therefrom and coupled to the fitting, and a coupling mechanism extending downwardly from the base. A tubular polygonal column is removably attached to the adapter by the coupling mechanism.
Also provided is a method of emplacing a tubular column including providing a sonic drilling apparatus having a fitting, and an adapter including a base having a socket extending upwardly therefrom, and a coupling mechanism extending downwardly from the base. Attaching the adapter to a tubular polygonal column with the coupling mechanism. Coupling the socket to the fitting, and driving the tubular polygonal column vertically into a supporting substrate to a depth desired and sufficient to provide stability to the tubular polygonal column employed for the construction of a structure.
Specific objects and advantages of the invention will become readily apparent to those skilled in the art from the following detailed description of a preferred embodiment thereof, taken in conjunction with the drawings in which:
Turning now to the drawings in which like reference characters indicate corresponding elements throughout the several views, attention is directed to
Sonic drilling apparatus 10 is utilized to drive column 16 into a supporting substrate 18 such as earth. In operation, column 16 can be driven through typical soil, concrete, asphalt and other substrates 18. By using resonant sonic drilling methods an oscillator is adapted to transmit sinusoidal pressure waves through column 16 to create a cutting action at the lower edge. The pressure waves are typically created by two counter-rotating, offset balance roller weights each having an eccentric axis located in the orbiting mass oscillator 12. Frequencies close to the natural frequency of column 16 are generated, thereby causing the column to vibrate elastically along its longitudinal axis. In the resonant condition, the column stores and releases energy, thereby generating large forces between the lower edge and the substrate. It will be understood that sonic drilling apparatus 10 can be carried by a drill vehicle, mounted on a tripod or other structure, and the like. These structures carrying sonic drilling apparatus 10 allow for transportation of apparatus 10 as well as accurate placement of column 16.

With additional reference to
In operation, a column 16 is coupled to adapter 15. Adapter 15 is then coupled to orbiting mass oscillator 12 by attachment to threaded fitting 14. Column 16 is then positioned over the location in which it is to be emplaced, and using the sonic drilling apparatus, driven vertically into the substrate to a depth desired and sufficient to provide stability to column 16. Column 16 is not rotated, but simply driven vertically downward. Column 16 is then employed as a column for the construction of a structure such as a parking structure, shade structure, building and the like. By employing sonic drill technology to emplace columns, holes need not be dug, and filler need not be replaced after positioning the column. The column is simply inserted through the substrate, which closely engages the column preventing removal thereof without the additional use of the sonic drill apparatus. Column 16 is driven into the substrate when the correct frequency is achieved for the material of the column to resonate.
To achieve an emplaced column, column 16 is at least 128 thousandths of an inch thick and preferably in the range of 128 to 150 thousandths of an inch thick. The material of column is steel being a high strength steel in the range of 85-100 KSI. The thickness and hardness scales are required to prevent welds forming column 16 from tearing loose, and to prevent the forces generated by sonic drilling apparatus 10 from damaging column 16.
