MOUNTING STRUCTURE AND MOUNTING METHOD FOR PILE-HEAD BASE PLATE TO STEEL-PIPE PILE IN BOLTED-CONNECTION STRUCTURE OF STEEL-PIPE PILE AND COLUMN

摘要

PROBLEM TO BE SOLVED: To provide the mounting structure or the like of the pile-head base plate to a steel-pipe pile in the bolted connection structure of the steel-pipe pile and a column in which a time up to the installation of the pile-head base plate to the pile after the steel-pipe pile is driven can be drastically reduced.;SOLUTION: A subplate 6 having a through-hole 6a in a size adapted to the outer peripheral section of the pile head of the steel-pipe pile 1 is constituted so that the pile head of the pile 1 is inserted into the through-hole 6a and the peripheral section of the through-hole is welded to the outer peripheral section of the pile head of the pile 1 on the top-face side of the subplate 6. The through-hole 3a in the size larger than the size of the outer periphery of the pile head of the pile 1 is formed to the pile-head base plate 3. The base plate 3 is superposed on the subplate 6 by the projection of the extra-length section of the pile head into the through-hole 3a so that a bolthole 3b is conformed to the bolthole 4b of the column-side base plate 4, and the peripheral section of the through-hole is welded on the top face of the subplate 6.;COPYRIGHT: (C)2005,JPO&NCIPI
