Claims

[Claims for Utility Model Registration] (1) A shaft portion is formed on the tip side of the tapered end portion, and a non-circular cross-sectional portion having a larger cross-sectional area than the shaft portion is formed on the tip side of the shaft portion via a step. A shaft bolt is formed, and a threaded portion is formed on the distal end side of this non-circular cross section, and a shaft is formed on the distal end side of a hole having a tapered end portion and a straight portion corresponding to the tapered end portion and the shaft portion of the shaft bolt. It has an inner surface with an engagement hole located on the outer circumferential side of the non-circular cross section of the shaft bolt with a gap through the step that contacts the step of the bolt, and forms a fastening portion that fits into the pipe to be fastened. A fastening member having an outer surface and further divided into a plurality of parts in the circumferential direction, and a non-circular cross-section hole that engages with the non-circular cross-section portion of the shaft bolt so as to be movable in the axial direction, and an engagement hole portion of the fastening member. a rotation operating member having an engaging portion on its outer periphery that is rotatable about an axis and engaged while restraining axial movement;
It consists of a holding member made of an elastic material that is wrapped or fitted around the outer periphery of the fastening member divided into a plurality of parts to collectively hold the fastening member, and the tapered end of the shaft bolt and the fastening part of the shaft and the fastening member are fitted into the pipe. ,
A part of the rotation operation member or a support portion protruding toward the end of the fastening part of the part and the fastening member is arranged between the pipe and the mounting member, and the internal thread provided on the attachment member is connected to the rotation of the rotation operation member. A fastening fitting for a structural pipe, characterized in that the male threaded part of the shaft bolt protruding from the operating member is tightened by the action of the operating member, and the fastening part of the fastening member is crimped onto the inner circumferential surface of the pipe. (2) The fastening part of the fastening member has a plurality of tapered grooves whose end portions have a small diameter, which are arranged in parallel in the axial direction via steps. Metal fittings. (3) The fastening fitting for a structural pipe according to claim 1 or 2, wherein the holding member is a tape coated with adhesive on the inner surface and wrapped around the outer periphery of the fastening member. (4) The fastening fitting for a structural pipe according to claim 2, wherein the holding member is an elastic ring that is fitted into the tapered groove of the fastening member and has a cutoff section at one location in the circumferential direction.
