CONNECTING STRUCTURE OF FILL-UP GROUND RECLAIMING INSERT AND ROUND STEEL SUPPORT BAR

摘要

PROBLEM TO BE SOLVED: To prevent a support bar from being broken by shearing force when reclaiming a fill-up ground by enhancing the shearing yield strength of the support bar in a connecting structure of a fill-up ground reclaiming insert and a round steel support bar.;SOLUTION: While forming a female screw part 15a on the depth directional inmost side in a connecting hole 15 of the insert I embedded in an earth retaining concrete panel P according to one end screw part 11 of the support bar B buried in the banking ground G, a fitting hole part 15b larger than a trough diameter of a female screw and having the almost same diameter as a shaft part 10 of the support bar B is formed in a depth range up to the female screw part 15a from an inserting port 16 of the connecting hole 15. The support bar B is connected to the insert I in a state of fitting the same columnar part 10a near the one end screw part 11 in the shaft part 10 over the length equivalent to the depth of the fitting hole part 15b when the one end screw part 11 is inserted into the connecting hole 15 and is screwed into the female screw part 15a.;COPYRIGHT: (C)2004,JPO
