There is disclosed an improved pile point for foundation piles such as the H-beam pile. The point provides an improved biting edge which eliminates skidding and slipping on inclined rock stratum or when the pile is used as a batter pile. The point includes a web and a pair of flanges positioned at the ends of the web and perpendicular thereto, the flanges including, typically, angled side portions to which are fixedly secured teeth-like protrusions. The latter provide a biting edge which grab hold of the supporting stratum, even when it is at a sharply inclined angle, to eliminate slipping and skidding on such surfaces. Such teeth-like protrusions are provided on a flattened portion of the web and flange affording additional biting edges. The latter protrusions can be arranged such that the point can provide improved biting regardless of its orientation relative to the rock stratum.
An improved point for a standard H-beam pile, which includes a web and two flanges, each of said flanges substantially perpendicular to said web and disposed at opposite ends of said web, said flanges each having side portions disposed in spatial relationship with the horizontal, wherein the improvement comprises at least one tooth-like protrusion fixedly secured to at least one of said side portions, said tooth-like protrusion extending substantially downward from said side portion when said pile is in a vertical position, said protrusion including a biting edge for grabbing and holding the rock stratum upon which the pile is to be supported, said protrusion shaped and disposed upon said side portion such that the forces developed upon contacting said rock stratum are distributed through said corresponding flange towards the webs of said point and H-beam pile.
