Technical Field
The present invention relates to a pile. In particular, the invention relates to, but is not limited to, piles for ground anchoring systems in building foundations.
Background
Reference herein to background art is not to be construed as an admission that such art forms part of the common general knowledge in australia or elsewhere.
In many industries, a common process involves winding a pile (e.g., a pole) into the ground to form a foundation. Piles are often a form of foundation that is cost effective, for example, piles may provide a reduced environmental impact compared to other foundations. Other advantages of pile foundations may also include ease of installation and reduced risk to personnel, since foundations are typically machine-threaded, for example.
The design of the pile is based on structural and geotechnical principles. Currently available screw piles and lobed piles are not always effective, particularly in wet land or land consisting primarily of gravel and sand. Such soils tend to be non-tacky or "loose", with little or no enough clay to bind the soil together. Wet or loose ground tends to slip off the sides of the blades of the lobed pile or the screw of the helical pile, respectively, resulting in a lower load-bearing capacity of the pile. Furthermore, conventional screw piles and lobed piles are also known to have very low lateral load bearing capacity.
It is believed to be desirable to provide a pile that overcomes or ameliorates one or more of the disadvantages or problems described above, or at least provides an alternative to the piles of the current form.
Disclosure of Invention
In one form, although not necessarily the only or broadest form, the invention resides in a pile comprising:
an elongated member; and
an anchor portion connected to the elongated member,
wherein the anchor portion has an arcuate member radially spaced from the elongated member.
The elongate member may be substantially cylindrical. The outer diameter of the elongated member may comprise any value, for example, from 50mm to 100mm, although no limitation should be inferred therefrom.
The elongate member may be hollow. The wall thickness of the elongated member may comprise any value from 2mm to 10 mm. Again, however, this is merely exemplary, and no limitation should be inferred therefrom. The elongate member need not be hollow, but may be solid.
The elongate member may be in the form of a shaft.
The elongated member may include a connecting portion.
The connecting portion may be located at an end (first end) of the elongate member. The connecting portion may be located at an opposite end of the elongate member (of the pile or pile section) to the anchoring portion.
The connecting portion may be configured to releasably connect to a machine. The machine may be in the form of a rotary power head, auger driver, or the like. The connecting portion may also be configured to releasably connect to another pile or pile section.
The connection portion may also (or alternatively) be configured to connect to a separate component. The separate member may be in the form of an extension member or an extension stake or another stake.
The anchor portion may be connected to a surface of the elongated member. The anchor portion may be secured directly to the elongated member or a surface of the elongated member.
The anchor portion may extend away from a surface of the elongated member.
The anchor portion may be located at (or generally towards) an end (second end) of the elongate member. The anchoring portion may be located at (or generally towards) the opposite end relative to the connecting portion.
The anchor portion may include at least one plate. The anchoring member may comprise two plates. Two plates may be connected to the elongate member at equal but opposite angles (i.e. at angles having equal angular extent but opposite directions) -in other words, one plate may be inclined by X degrees in one direction (one way) relative to the elongate member (or the longitudinal axis of the elongate member) and the other plate may be inclined relatively by the same amount relative to the elongate member (or the longitudinal axis of the elongate member). The plate may be flat/planar. The plate may also be arcuate in shape (i.e. like a partial disc).
The (or each) plate may have an arcuate distal edge. The arcuate distal edge (and all portions thereof) may be substantially equidistant (i.e., a constant distance) from the outer surface of the elongate member.
The (or each) plate may have a guide portion which engages with the ground as the pile is screwed into the ground. The guide portion may comprise a lower portion of the arcuate distal edge that is not connected to or covered by the respective arcuate member.
The (or each) arcuate member may extend from the arcuate distal edge of the respective plate in a direction parallel to the elongate member (or parallel to the longitudinal axis).
The (or each) arcuate member may extend concentrically with the elongate member about the longitudinal axis.
The (or each) arcuate member may be attached to the arcuate distal edge of the (or each) plate along intersecting arcs on the inner surface of the arcuate member. The intersecting arc may extend laterally and substantially along a center of the inner surface.
The (or each) arcuate member may extend only partially (rather than all the way) along the arcuate distal edge of the (or each) plate, leaving a lower portion of the arcuate distal edge of the (or each) plate exposed.
The first arcuate member may be connected to the first plate and the second arcuate member may be connected to the second plate. The first and second arcuate members may be oriented at equal but opposite angles (i.e., at angles having equal angular extent but opposite directions) relative to the longitudinal axis of the elongate member-in other words, one arcuate member may be inclined by X degrees in one direction relative to the elongate member (or the longitudinal axis of the elongate member) and the other arcuate member may be inclined relatively by the same amount relative to the elongate member (or the longitudinal axis of the elongate member).
The first arcuate member may have an upper (curved) edge and a lower (curved) edge.
The second arcuate member may have an upper (curved) edge and a lower (curved) edge.
The upper (curved) edge of the first arcuate member and the upper (curved) edge of the second arcuate member may lie in planes that are perpendicular or angled relative to the longitudinal axis of the elongated member (in the same plane, or parallel planes, or differently oriented planes relative to each other).
The lower (curved) edge of the first arcuate member and the lower (curved) edge of the second arcuate member may also lie in planes that are perpendicular or angled relative to the longitudinal axis of the elongated member (again, in the same plane, or parallel planes, or differently oriented planes relative to each other).
The pile may further comprise a second anchoring portion connected to the elongate member.
The second anchor portion may be the same as or different from the first anchor portion described above. The second anchoring portion may comprise two plates. The two plates of the second anchoring portion may be oriented at equal but opposite angles relative to the longitudinal axis of the elongate member. The two plates may be arcuate.
The second anchor portion may be spaced apart from the first anchor portion along the longitudinal axis of the elongate member.
The second anchoring portion may be located closer to an end of the elongate member opposite the (second) end having the connecting portion (i.e., closer to the first end of the elongate member).
The second anchor portion may be located between the connecting portion and the first anchor portion. There may also be a third (or more) anchoring portion(s) connected to the elongated member.
In one particular form, the invention relates to a pile comprising:
an elongated member having a longitudinal axis; and
an anchor portion connected to the elongated member,
wherein: the anchor portion has a plate and an arcuate member radially spaced from the elongate member; the plate having an arcuate distal edge; the plate is connected to the elongated member at a non-perpendicular angle relative to the longitudinal axis; the arcuate member is located on the arcuate distal edge of the plate; and the plate has a pilot portion including a lower portion of the arcuate distal edge which extends beyond the arcuate member and engages the ground as the pile is screwed into the ground.
Another form of the invention resides in a method for making a pile, the method including the steps of:
connecting an anchoring member to the elongate member or a surface of the elongate member; and
the arcuate members are connected relative to the anchor members,
wherein the arcuate member is radially spaced from the elongated member.
The anchoring member may be an arcuate plate.
The step of attaching the anchoring member to (a surface of) the elongate member may comprise welding the anchoring member thereto.
The step of connecting the arch member relative to the anchor member may include welding the arch member to the anchor member.
The method may further include connecting a second anchor portion to the elongate member.
The step of attaching the second anchoring portion to (a surface of) the elongate member may comprise welding the second anchoring member thereto.
