PIER STUD CONNECTION STRUCTURE AND PIER STUD CONNECTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pier stud connection structure which occupies a small construction area, contributes to a shortened construction period and reduced construction costs, and exerts sufficient durability at a connection, and to provide a pier stud connecting method.;SOLUTION: The pier stud connection structure for connecting between a pile head 3a of an RC pile 3 and a base structure 4b of a steel square cylindrical pier 4, is implemented by a connection unit 5 which is formed of the base structure 4b; an extended plate 15 extended from each flange 12 of the base structure 4b; connecting reinforcements 8 protruded upward form the pile head 4b; and a cylindrical steel shell 21 externally fitted onto the base structure 4b and the connecting reinforcements 8, and rigidly connected to the base structure 4b via the extended portions 15, to thereby restrain poured joining concrete 31 from the periphery. According to the pier stud connection structure, a number of deviation preventive holes 16 are formed in webs 11, the flanges 12, ribs 13, 14, and the extended portions 15 of the base structure 4b, for transmitting shearing force from the base structure 4b via the joining concrete 31 to the pile head 3a.;COPYRIGHT: (C)2006,JPO&NCIPI
