STRUCTURE AND METHOD FOR JOINING CAST-IN-PLACE CONCRETE PILE AND REINFORCED CONCRETE FOOTING BEAM

摘要

PROBLEM TO BE SOLVED: To provide a structure and method for joining a cast-in-place concrete pile and a footing beam by which the cast-in-place concrete pile and the footing beam are joined to each other with simple construction without constructing a foundation.SOLUTION: A footing beam 20 comprises a footing beam central part 202 arranged between two cast-in-place concrete piles 10, and a footing beam end part 201 joined to a head of the cast-in-place concrete pile 10. The footing beam end part 201 has a width approximately equal to the diameter of the head of the cast-in-place concrete pile 10, and is provided with a third main reinforcement which is juxtaposed with a second main reinforcement of the footing beam central part 202, is orthogonal to a first main reinforcement 11 together with the second main reinforcement to come into contact with the outer peripheral part of an installation range 101, and is arranged so as to penetrate the head of the cast-in-place concrete pile 10. The cast-in-place concrete pile 10 and the footing beam 20 are joined to each other by driving concrete into the respective main reinforcements.
