REINFORCING STRUCTURE FOR COUPLER OF STEEL PIPE PILE

摘要

PURPOSE: A reinforcing structure for a coupler of a steel pipe pile is provided to improve the quality of a coupler-reinforcing structure of a steel pipe pile and to enhance a structure against initial tensile force. CONSTITUTION: The reinforcing structure for a coupler of a steel pipe pile(10) comprises: a coupling ring(20) interposed into the steel pipe pile(10) and bolted to the steel pipe pile(10), and a bearing ring(22) formed on the coupling ring(20) and placed over the upper end of the steel pipe pile(10); a bearing plate(28) located to the deep inside of the steel pipe pile(10) through many rods(26) of the bearing ring(22) to support concrete and to reinforce footing concrete; and many bracing blocks installed into the steel pipe piles(10) by a fixing pin to set up against initial tensile force and compressive force of concrete filled in the steel pipe piles(10).
