The screw rod 12 is screwed to the base plate 1 by a pair of thick nuts 13 that are integrated with the base plate 1 by fixing means such as caulking and welding, and disposed inside the through hole. Further, it is fixed by a thin plate-like thin nut 14 and is made up of all screw bolts standing upright to the base plate 1, and the curved band 2 protrudes so as to be horizontal with the arc band 21 at the center position and both longitudinal ends thereof. For example, it is assumed that a fastening piece 22 having the same width as the arc band 21 is formed by press molding, and the nut 4 has a male screw diameter of the screw rod 12. There as by a hexagonal nut having a female screw was. At this time, the level band A can be supported according to the outer diameter of the pipe pipe B as a plurality of types in which the dimensions of the base plate 1, the screw rod 12, the curved band 2, and the nut 4 are changed. The base plate 1 is about 15 to 22 cm long and about 2.5 to 4 cm wide, and the screw rod 12 is about 10 to 20 cm high and about 1 to 2 cm thick and curved. The arc band 21 of the band 2 has a width of about 2.5 to 4 cm in which the outer periphery of a plurality of pipe pipes B of about 5 to 15 cm is fitted or inscribed in the outer periphery, and the fastening piece 22 The nut 4 has the same width as the arc band 21 and has a length of about 4 cm, and the nut 4 has a female screw corresponding to the thickness of the screw rod 12 and is used in accordance with the outer diameter of the pipe B. As That.

  The curved band 2 arranged oppositely has the screw rod receiving holes 23 in the fastening pieces 22 at both ends in the longitudinal direction thereof. In the present example, the screw rod receiving holes 23 serve as out-of-plane communication grooves 23b. The fastening piece 22 at one end in the longitudinal direction is arranged on one curved band 2 arranged opposite to the fastening piece 22 at the other end in the longitudinal direction and the fastening pieces 22 on both ends in the longitudinal direction of the other curved band 2 arranged opposite to each other. Each screw rod receiving hole 23 is a circular through hole or a long hole in the longitudinal direction, in this example, an in-plane through hole 23a of the long hole. At this time, the screw rod receiving hole 23 is an out-of-plane communication groove. The bending band 2 having the fastening piece 22 at one end in the longitudinal direction, which is 23b, is used as the upper one bending band 2a arranged oppositely.

It is a thick piece-shaped molded part having a U-shaped cross section at the position of the opposed bent piece 32. In this example, the retrofitting fixture 3 has its substrate 31 slightly larger than the width of the curved band 2. The width of the front and back is a plane rectangle having a width that covers the screw hole receiving hole 23 from the front end of the fastening piece 22 in the protruding direction. Each of the front and rear ends intersecting with the protruding direction of the attachment piece 22 is also suspended, and a receiving groove 33 for receiving screw rods is formed as an out-of-plane communication groove 23b in the fastening piece 22 at one end in the longitudinal direction when the nut 4 is fastened. Parallel to or crossing in this example, parallel in this example In this case, the receiving groove 33 of this example is arranged from the in-plane intermediate position of the substrate to one of the opposing bent pieces 32. This one bending piece 32 is arranged so as to be cut out at the same time. At this time, the substrate 31 of the retrofitting fixture 3 has a width of about 2.5 to 4 cm, for example, and a width of about 2 to 3 cm from the front end of the fastening piece 22 in the protruding direction. The opposing bent piece 32 is at least twice the height of the fastening piece 22 of the bending band 2 with respect to the thickness of 2 mm, for example, and has a considerable margin, for example, the same height of about 1 cm. Also, the receiving groove 33 for receiving the screw rod is an opposed bent piece on one side from a position where the width of the screw rod diameter is added to the middle position in the front and rear of the plane of the substrate 31, that is, the center position. As a plurality of types that are used in accordance with the width of the fastening piece 22 of the curved band 2 and the thickness of the screw rod 12 so as to be slightly larger than the diameter of the screw rod 12 reaching 32. is there.
