Anchoring joint for steel pile head and concrete footing and thereof construction structure

摘要

PURPOSE: A fastener for the reinforcement coupling between a steel pile and a concrete base and coupling structure using the fastener are provided to improve the convenience of construction and the economic efficiency by adopting mechanical connection using a steel and concrete composite instead of the work of welding inside a steel pipe. CONSTITUTION: In the fastener for coupling a head portion of a steel pile and a concrete base of a structure, a basic anchor iron bar coupling part(31), a steel pile coupling part(32), and a reinforced concrete anchor part(33) are integrally formed. The basic anchor iron bar coupling part is shaped into a female screw form so as to be coupled with a basic anchor iron bar whose lower end is processed into a screw form. The steel pile coupling part is formed at the lower side of the basic anchor iron bar coupling part and has a bolt hole(35) at the side thereof. The reinforced concrete anchor part is formed at the lower side of the steel pile coupling part.
