Document Type and Number:
Japanese Patent JP2016006287
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a practical concrete pile that has high peripheral surface frictional force for enabling high bearing capacity and high pulling-out bearing strength, is capable of being inexpensively and easily manufactured, and hardly allows a crack caused by internal stress derived from heat of hydration to be generated at the time of manufacturing the concrete pile.SOLUTION: A concrete pile 1 is formed in a quadrangular prism shape and has a plurality of projections 3, 3, .. formed on two opposite faces of an outer periphery of the pile along the longer direction of the pile. The projections 3, 3, .. have a U-shaped horizontal cross section and two side faces forming a taper. The concrete pile 1 includes a reinforcement structure 6 disposed inside, where the reinforcement structure 6 is made by welding, at predetermined intervals, four reinforcing bars 4, 4, .. to quadrangular ring bodies 5, 5, ...
