METHOD FOR ERECTING PILE-COLUMN IN BUILDING USING PILE AS COLUMN, AND PILE-COLUMN SUPPORT BAND FOR USE THEREIN

Japanese Patent JP3129676

B2

PROBLEM TO BE SOLVED: To secure the pile-column erecting accuracy needed to provide a pile-column with functions as both a pile and a column in a building which uses piles as columns.
SOLUTION: A vertical hole 14 having a slightly larger diameter than a pile-column 12 is dug slightly deeper than design pile penetration depth, and after a pile-end consolidating liquid and a pile-periphery fixing liquid are injected into the vertical hole 14, the lower portion of the pilecolumn 12 is sunk into the vertical hole 14. H-steel members 18x, 18x, 18y, 18y are assembled in the form of a well around the opening of the vertical hole 14 above the ground to form a frame 18. Then a pile-column support band 19 is attached to the pile-column 12, with the lower end of the pile-column support band 19 set in a position which is higher than the lower end of the pile-column 12 by the total length of the design pile penetration depth and the height of the frame 18. The pile-column support band 19 is split into semicircular steel members 20, 20, and is pressed against the pile-column 12 by bolting together flanges 21, 21 at their circumferential ends. A projection 23 is projected radially outwards from the circumferential center of each semicircular steel member 20, and, by hooking the projection 13 to the H-steel member 18x, the pile-column 12 is suspended vertically inside the vertical hole 14 while being supported on two front and rear points along the Y-direction.
