REINFORCING-COUPLING STRUCTURE OF A STEEL PIPE PILE HEAD AND A CONCRETE FLOOR SLAB CAPABLE OF INCREASING THE BINDING STRENGTH BETWEEN A PILE AND A FOUNDATION BY A FASTENER AND HAVING STABLE BEARING STRENGTH AGAINST EXTERNAL FORCE SUCH AS BENDING MOMENT AND SHEAR STRENGTH, ETC. USING A FASTENER AND THE FILLED CONCRETE

摘要

PURPOSE: A reinforcing-coupling structure of a steel pipe pile head and a concrete floor slab is provided to improve the binding strength of a pile and a foundation by a fastener having a connecting bar, to prevent the slide of a pile by a fixing bar and to have the stable bearing strength against external force by a fastener and the filled concrete. CONSTITUTION: The reinforcing-coupling structure of a steel pipe pile head and a concrete floor slab comprises the steps of coupling a fastener(10) having many connecting bars(14,14') on the upper end of a steel pipe pile(1) and coupling a steel pipe pile(1) and a concrete floor slab. The steel pipe pile(1) is provided with many fitting holes(2,2'), and the fastener(10) comprises the steps of erecting many vertical fixing bars(12,12') on the upper side of an isolation plate(11), erecting many connecting bars(14,14') to the inside of a fixing coil(13) radially, coupling the end of the vertical fixing bars(12,12') and the fixing coil(13), and inserting additional fixing bars(3,3') into the fitting holes(2,2') of the steel pipe pile(1), then placing the fixing coil(13) of the fastener(10) inserted into the front of the steel pipe pile(1) to couple the concrete floor slab, the steel pipe pile(1) and the fastener(10) firmly.
