Claims

[Scope of utility model registration request]

A joint pipe with an outer diameter that can be inserted into a beam, a nut mounting part that is integrally formed with a recess in a part of the joint pipe, and a blind nut that is attached to the nut mounting part using a nut holding plate. and,
The nut mounting portion has an oval nut insertion hole formed therein, the nut holding plate has an opening, and the blind nut has a bolt that is screwed into the blind nut. The lower part has a length part, and the length part is shorter than the sum of the thickness of the nut mounting part and the thickness of the joint pipe, and has an elliptical cylinder shape. The diameter of the shaft is shorter than the diameter of the major axis of the nut insertion hole and longer than the diameter of the minor axis of the nut insertion hole, and the diameter of the minor axis of the length is shorter than the diameter of the minor axis of the nut insertion hole. A pair of grooves into which a nut holding plate is fitted are formed on the long axis side of the length, and the distance between the grooves is shorter than the length of the opening in the longitudinal direction. Fittings for protective fences.
