Title: COUPLING STRUCTURE FOR FIBER REINFORCED PLASTIC STRUCTURE MEMBER AND MACHINING METHOD FOR COUPLING SECTION
Abstract:
Provided are a machining method and a coupling structure to be used as a structure member by joining a coupling member to an end of a fiber reinforced plastic structure member. A coupling structure for a fiber reinforced plastic structure member: a fiber reinforced plastic structure member 1 for which an end of the fiber reinforced plastic structure member is narrowed; a reinforcing member 4 that inhibits expansion by adhering to the outer circumference of the narrowed portion of the fiber reinforced plastic structure member; a locking member 2 that is provided with a through-hole 2a in the axial direction and that fits into a narrowed portion 1a of the fiber reinforced plastic structure member 1; a coupling anchoring member 3 that is provided with a rotation stop on the side thereof; and a spacer 5 that restricts only the rotation of the coupling anchoring member 3 and that is mounted between a member 7 to be coupled and an end of the fiber reinforced plastic structure member 1 by passing the coupling anchoring member 3 through so as to be able to slide in the axial direction. The coupling anchoring member 3 is coupled by being screwed onto threads 7a of the member 7 to be coupled by rotating the spacer 5.
