Abstract

PURPOSE: To increase the final strength of a prestressed concrete pile after the generation of cracks in the concrete by embedding in the prestressed concrete pile a plurality of deformed bars in parallel with prestressed concrete steel materials.
CONSTITUTION: The highly strong prestressed concrete pile is prepared by the pretensioning system: Prestressed concrete steel material 1..., spiral hoop reinforcement 2, deformed bars 4... are cagelikely arranged, then with tensile forced applied to the prestressed concrete steel materials 1, concrete 3 is placed, and after the concrete 3 has hardened, the tensile force is removed from the prestressed concrete steel materials 1, to allow the concrete 3 to be prestressed. Thereby, since the deformed bars 4... and the concrete 3 are stuck to each other, the deformed bars 4 are also prestressed. Consequently, if the stress previously applied to the concrete 3 has decreased, the prestressed concrete pile still has been sufficiently prestressed as the whole.
