THE BOLT CAP COUPLING STRUCTURE OF PRETENTIONED SPUN HIGH STRENGTH CONCRETE PILES AND PIPE PILE USING THE SAME

摘要

PURPOSE: A connection structure of a PHC pile using a bolt cap and a pile using the same are provided to easily and securely connect PHC piles to each other and to improve the connecting strength of the PHC piles. CONSTITUTION: A connection structure of a PHC pile using a bolt cap is composed as follows. Lower and upper bolt caps(100,200) are formed in both ends of PHC piles(400,400'). Steel bar coupling holes of the lower and upper bolt holes touching each other correspond to each other. Bolts(300) inserted into a watertight box(221) are coupled to coupling nut units.
