摘要

PROBLEM TO BE SOLVED: To provide a construction method reutilizing existing piles at re- erection and a building structure reutilizing the existing piles capable of easily reutilizing the existing piles as the piles of a new building by introducing a technique that normal vertical force is transferred between the existing piles and the direct foundation of the new building but earthquake horizontal force is not transferred or a technology that the normal vertical force and the earthquake horizontal force are transferred but earthquake bending moment is not transferred when the earthquake resistance of the existing piles is relatively high, thereby minimizing the cracks occurring on the existing piles, and improving durability. SOLUTION: In this construction method reutilizing the existing piles as the piles of the new building when a building is re-erected, a supporting means that transfers the vertical force but does not transfer the earthquake horizontal force between the pile head sections of the existing piles and the direct foundation such as the mat slab of the new building or a supporting means that transfers the vertical force but does not transfer the earthquake bending moment is installed to reutilize the existing piles.
