FOUNDATION PILE AND METHOD OF JOINING OF STEEL PIPE PILE OF FOUNDATION PILE WITH STRUCTURE

摘要

PURPOSE:To reduce a construction cost, by a method wherein each of anchor bolts is emerged upward from the upper end of a pile and is secured in a space between the top parts of driven steel pipe pile by means of concrete, and a structure placed on the piles is coupled integrally to the piles by means of the anchor bolts. CONSTITUTION:A foundation steel pipe pile 1 is driven in a ground, and a round steel 8 is welded and secured in an annular manner to the inner surface of the pile 1. After anchor bolts are attached to the pile 1, expansion concrete is placed in the upper part of the pile 1, and a filling substance 7 is formed to form a foundation pile K. After regulating mortar is placed on the upper surface of the filling substance 7 to form a bed mortar 5, the structure 6 is placed on the bed mortar 5 to tighten the structure against anchor bolts 4 by means of nuts.
