<p>AN IMPROVED POINT ATTACHMENT FOR FOUNDATION PILE There is disclosed on 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.</p> |
