A notch portion 13 is formed, and one set of the notch portions 13 are formed at positions facing each other.
This will be explained in detail below.

The pipe holding band 1 will be explained.
As shown in FIG. 1(a), the pipe holding band 1 includes a pipe holding part 2 in which the band plate material is formed in a semicircular shape, and a pipe holding part 2 extending straight outward from the base end 21 of the pipe holding part 2. It has one set of holding members 4 each having a mounting portion 3 extending therefrom. By connecting the other end portions 22 of one set of pipe holding portions 2 to each other, the pipe holding band 1 can be opened and closed around the other end portion 22. As shown in FIG. 2(a), two circular insertion holes 31 are formed in the mounting portion 3 in parallel in the longitudinal direction.

Next, the temporary fixing piece 10 will be explained.
The temporary fixing piece 10 is made of a rectangular elastic plate. The elastic plate material may be a flexible metal material or a flexible resin material. The temporary fixing piece 10 is formed to have a smaller length in the longitudinal direction than the attachment part 3, and is temporarily attached when it is secured to a fastener 5 such as a bolt inserted into the insertion hole 31 of the attachment part 3. The entire piece 10 is formed in a size and shape that overlaps the mounting portion 3 (see FIG. 2(b)). The temporary fixing piece 10 has two rectangular holes 11 arranged in the longitudinal direction. The hole 11 penetrates the temporary fixing piece 10 in the thickness direction. The hole 11 has opposing edges 12 that are parallel to each other. The opposing edge portion 12 on the long side of the hole 11 is labeled 12A, and the opposing edge portion 12 on the short side of the hole 11 is labeled 12B. The opposing edge portion 12A on the long side extends in the longitudinal direction of the temporary fixing piece 10, and the opposing edge portion 12B on the short side extends in the lateral direction of the temporary fixing piece 10. A notch 13 extending in the short direction of the temporary fixing piece 10 is formed in each of the opposing edges 12A on the long side so as to move away from the opposing edges 12A. That is, the temporary fixing piece 10 has a hole 11 formed in a rectangular shape (long hole) and a set (two) of notches 13 . A pair of notches 13 are formed at opposing positions, respectively, so that the fixing tool 5 can be stably fixed. Further, the distance W3 between the outer end portions 13a, 13a of the cut portions 13, 13 is formed to be larger than the diameter of the insertion hole 31 of the attachment portion 3. It is desirable that the notches 13 are provided at the center of each opposing edge 12 .

In the side view of the attachment part 3 in FIG. 2(a), the hole 11 and the notch 13 of the temporary fixing piece 10 are shown by two-dot chain lines. The separation distance W1 between the opposing edge portions 12A, 12A on the long side of the hole portion 11 is smaller than the diameter of the insertion hole 31 of the attachment portion 3. The separation distance W2 between the opposing edges 12B, 12B on the short side of the hole 11 is set to be larger than the diameter of the insertion hole 31 of the attachment portion 3. In the thickness direction of the attachment portion 3, the holes 11, 11 are formed at positions overlapping with the insertion holes 31, 31 of the attachment portion 3.

Next, how to use the temporary fixing piece 10 will be explained.
The fixing tool 5 is inserted into the insertion hole 31 of one of the attachment parts 3. As a result, the tip portion 51 of the fastener 5 protrudes inward of the attachment portion 3 of the pipe holding band 1. Then, by press-fitting the fixing tool 5 from the tip portion 51 into the hole 11 of the temporary fixing piece 10, as shown in FIG. 2(b), which is a sectional view taken along the line XX in FIG. 1(a), The temporary fixing piece 10 is locked to the fixing tool 5.

Since the temporary fixing piece 10 is made of an elastic plate material, an elastic biasing force acts so that the opposing edge 12A on the long side and the surrounding area sandwich the fixing tool 5. This makes it difficult for the temporary fixing piece 10 to fall off from the fixing tool 5. Further, if the fixing tool 5 is a bolt or the like having a threaded groove, a part of the opposing edge portion 12A fits into the threaded groove, so that the temporary fixing piece 10 becomes more difficult to fall off from the fixing tool 5. Since one of the attachment parts 3 is interposed between the head 52 of the fastening tool 5 and the temporary fixing piece 10, the fastening tool 5 becomes difficult to fall off from the pipe holding band 1. Use of such a temporary fixing piece 10 is effective when temporarily fixing the fixing tool 5 to the pipe holding band 1 when packing the pipe holding band 1 or using the pipe holding band 1. Since the fixing device 5 can be packed in advance in a state where it is temporarily fixed to the mounting part 3 using the temporary fixing piece 10 (see FIG. 1(a)), the pipe holding band 1 can be used immediately after being unpacked. becomes possible. Since the fastening tool 5 is fixed by the temporary fixing piece 10, the fastening tool 5 is prevented from falling during work, and there is no need to hold down the fastening tool 5 by hand to prevent it from falling during work. The installation work of the pipe holding band 1 can be quickly performed.

Since the temporary fixing piece 10 of this embodiment has a rectangular hole 11 and a set of notches 13, it can be manufactured easily and at a lower cost than that described in Patent Document 1. It is possible to reduce the Further, since the hole 11 is formed so that the separation distance W1 between the opposing edges 12A, 12A on the long side is smaller than the diameter of the insertion hole 31 of the attachment part 3, the fixing tool 5 can be firmly sandwiched therein. This makes it easier for the elastic biasing force to work. Furthermore, the separation distance W2 between the opposing edges 12B on the short side, which is also the length of the opposing edges 12A on the long side, is larger than the diameter of the insertion hole 31 of the attachment portion 3. Therefore, when the fastener 5 is inserted into the hole 11, the peripheral part of the hole 11 is easily deformed, and the fastener 5 is easily inserted into the hole 11.

Next, a method for holding the pipe holding band 1 on the pipe 8 will be explained with reference to FIG. 3. Note that here, the pipe 8 is assumed to be a vertical gutter that is fixed by a leg member 7 attached to an outer wall of a house or the like.
The holding members 4, 4 are opened around the other ends 22, 22 of the pipe holding parts 2, 2. Then, the pipe holding band 1 is moved so that the pipe 8 is located within the pipe holding parts 2, 2. Once the pipe 8 is located within the pipe holding parts 2, 2, the holding members 4, 4 are closed around the other ends 22, 22 of the pipe holding parts 2, 2. As shown in FIG. 3(a), the insertion hole 31 of one attachment part 3, the hole 11 of the temporary fixing piece 10, the elongated hole 71 of the foot member 7, and the insertion hole 31 of the other attachment part 3 are inserted in this order. The fixing tool 5 is inserted, and the tip end 51 of the fixing tool 5 is fastened with the nut 6 (see FIG. b)). As described above, the pipe holding band 1 holds the pipe 8 with the pipe holding parts 2, 2.

The cut portion 13 is formed to extend in the longitudinal direction away from the opposing edge portion 12A on the long side. In such a temporary fixing piece 10D, the proportion occupied by the hole 11 in the longitudinal direction of the temporary fixing piece 10D can be reduced. Therefore, even if the intervals between the plurality of insertion holes 31 of the attachment part 3 are narrow, it is easy to form the holes 11 in the number corresponding to each of the insertion holes 31 of the attachment part 3 in the temporary fixing piece 10D. . Even in the temporary fixing piece 10D in which such a hole 11 is formed, the hole 11 and its surrounding area are easily deformed when the fixing tool 5 is inserted due to the opposed edge portion 12A on the long side.
