PROBLEM TO BE SOLVED: To provide a weldless joint for a pile at low cost, which uses a reduced number of members and has satisfactory working efficiency. SOLUTION: This weldless joint for a pile includes a plurality of arcuate connection plates which are formed by radially dividing a cylinder, made to straddle over the metal fittings at both ends of piles to be connected to each other, and fitted to the outer peripheries thereof; and ribs and grooves which extend in the circumferential direction of the piles and which are fitted between the inner peripheral surface of the arcuate connection plate and the outer peripheral surfaces of the metal fittings at both ends. Inter-plate fixing projections are integrally provided to the outer surface of the arcuate connection plate at both ends. The weldless joint further includes fixing fittings for fixing the inter-plate fixing projections at the ends of the mutually adjacent arcuate connection plates. The two inter-plate fixing projections of the arcuate connection plates adjacent to each other are tapered in the pile axis direction, and the cross section thereof is formed in a dovetail form. The fixing metal fitting comprises a tapered dovetail groove to which the tapered dovetail form is fitted. The two projections adjacent to each other are fitted into the dovetail groove while sliding in the tapered direction. COPYRIGHT: (C)2011,JPO&INPIT
