PHC pile head cutting work and reinforced concrete structure for jointing scaffolding structural steel and construction method therof

摘要

PURPOSE: A structure of a head portion of a PHC pile for connecting structural steel of a temporary facility is provided to obtain stability by having a head portion of a PHC pile in order to have a precise horizontal surface in a head portion and to have economic feasibility by recycling a head reinforcing plate after constructing the head portion. CONSTITUTION: A structure of a head portion of a PHC pile for connecting structural steel of a temporary facility comprises a plurality of auxiliary reinforcing bars(20), and one or more stirrup bars(22), an inner form, a plurality of level regulating nuts(26), and a level regulating fixing bolt(28). The auxiliary reinforcing bars are arranged in between strands(12), thereby perpendicularly inserted. The stirrup bars connect the auxiliary reinforcing bars and strand. The inner form is supported by a crushed cross section of a PHC pile. The level regulating fixing bolt is all or selectively fixed to the plurality of auxiliary reinforcing bars. The height of level regulating nuts is adjusted because the level regulating nuts are joined to a plurality of level regulating nuts.
