Rope End-Fastening Method, Rope with End Fastener, and End Fitting for Use in Rope End-Fastening Method

摘要

A rope terminal fixing method is provided, which may be used easily at a construction site, causes less shearing load, and may reliably prevent the falling-off of the rope.;The rope terminal fixing method comprises the following steps. A tubular terminal metal fitting which comprises a proximal opening, a distal opening, and a through hole communicating the proximal and distal openings is prepared. A terminal of a rope is inserted through the proximal opening into the through hole, a portion of the terminal of the rope extended from the distal opening is loosened, and a diameter-enlarging member is fixed to a core wire of the rope. Then, the terminal of the rope is brought back into the through hole. A fixed width portion extending in an axial direction of the terminal metal fitting is pressed from the outside in a circumferential direction by swaging, such that a protrusion constraining the rope so as to reduce its diameter is formed in the through hole. The diameter-enlarging member cooperates with an end of the protrusion located on the distal opening side to constrain surrounding wires other than the core wire in a sandwiching manner. A rope with terminal fixing tools, which comprises the terminal fixing tools attached thereto by this method, is also provided.

1. A rope terminal fixing method comprising the steps of:
preparing a tubular terminal metal fitting having a proximal opening formed at its proximal end, a distal opening formed at its distal end, and a through hole communicating the proximal opening and the distal opening; inserting a terminal of a rope through the proximal opening into the through hole to extend a portion of the terminal of the rope out of the distal opening; enlarging a diameter of the terminal of the rope; bringing the terminal of the rope back into the through hole; and pressing the terminal metal fitting from the outside in a circumferential direction to make a diameter of the through hole smaller than the maximum diameter of the diameter-enlarged terminal of the rope and form a protrusion on an inner surface of the through hole, the protrusion pushing against an outer peripheral surface of the rope to constrain the rope within the through hole.
