A side bar 28 is detachably attached to the tip of each spoke bar 3 of the drum body 10 along the same direction as the spoke bar 3. That is, as shown in FIGS. 5 and 7, the side bar insertion cylinder 26 is arranged and fixed along the same direction as the spoke bar 3 on the oblique side of the tip of each spoke bar 3. The side bar insertion cylinder 26 is opened on the side close to the outer periphery of the ring body 4, and a compression spring 27 is internally provided therein, and the inner part of the side bar insertion cylinder 26 is formed on the bottom plate portion of the side bar insertion cylinder 26. The structure is fixed so that it does not come out.
[0014]
The side end of the side bar 28 is inserted into the side bar insertion cylinder 26, and the remaining portion is disposed outside the outer peripheral surface of the drum body 10 (or the outer peripheral portion of the ring body 4). Therefore, the ring bundle-like wiring / pipe material A attached to the drum main body 10 is a member that prevents the wiring / pipe material A from protruding sideways. As shown in FIGS. 7 and 10, an L-shaped engagement piece 29 that engages with the ring body 4 is integrally attached to a portion near the base end portion of the side bar 28. Yes.
[0015]
Therefore, the L-shaped engagement piece 29 is compressed as it is in a positional relationship where the engagement piece 29 and the ring body 4 do not interfere such that the L-shaped engagement piece 29 is parallel to the side surface of the drum body 10 (see FIG. 8). The side bar 28 is pressed until the entire engagement piece 29 is positioned inside the ring body 4 against the compressive force of the spring 27, and the base end portion is inserted through the side bar insertion cylinder 26 (FIG. 9). In this state, when the side bar 28 is rotated by a predetermined angle in the direction in which the engagement piece 29 and the ring body 4 are engaged, and the pressing force F against the side bar 28 is released, the compression spring 27 is restored. The side bar 28 protrudes by a predetermined length from the side bar insertion cylinder 26 by force, and the engagement piece 29 and the ring body 4 are engaged with each other, and the state is maintained (see FIGS. 10 and 11). ). Thereby, the side bar 28 is attached to the tip of each spoke bar 3 of the drum body 10 along the same direction as the spoke bar 3.

Further, the bald material fixing tool 9 can be turned toward the sidebar insertion cylinder 26 due to its shape, but in a state where the sidebar 28 is inserted into the sidebar insertion cylinder 26, the bald material is fixed. Since the side bar 28 is disposed substantially on the side of the fixture 9, the curling material fixture 9 is prevented from rotating in the above direction.
[0017]
Then, attaching the new wiring and piping material A in the drum D ₁ is performed as follows. First, as shown in FIG. 12, removing all the side bar 28 of one side of the drum D _1. To remove the side bar 28, the side bar 28 is pressed against the restoring force of the compression spring 27 to release the engagement between the engagement piece 29 and the ring body 4. In this state, the side bar 28 is When the pressing force F is released by turning 90 ° or more, the side bar 28 is removed from the side bar insertion tube 26. Since the outer diameter of the drum D ₁ is about 3 m and is large, the removal of the side bar 28 described above is performed by rotating the drum D ₁ by a predetermined angle while the drum D ₁ is supported on the gantry B ₁ . It is desirable to perform it at a position where the worker can work most easily. Since the side bar 28 protrudes in the radial direction of the drum main body 10, the side bar 28 tends to become an obstacle when the drum D ₁ is transported and stored. Therefore, all the side bars 28 may be removed during the transport and storage. desirable.
[0018]
Next, after removing the retaining ring 19 from the shaft retaining box 21, the drum D ₁ is lifted upward to remove the drum D ₁ from the gantry B _{1 so} that the drum D ₁ is in a single state. Then, as shown in FIG. 12, the ring bundle-like wiring / piping material A is lifted, the drum body 10 of the drum D ₁ is inserted inside the wiring / piping material A, and the drum body 10 is Install wiring / piping material A on the outside.

Then, the drum D _{1 on} which the wiring / piping material A is mounted is lifted (see FIG. 14), and both ends of the drum shaft 1 are inserted into and supported by the box bearings 2 of the gantry B ₁ . When the retaining ring 19 is attached to the retaining box 21, the drum shaft 1 does not come out from each box bearing 2, and the drum D ₁ on which the wiring / piping material A is mounted is supported by the gantry B ₁ (FIG. 1). Or see FIG.
[0019]
After that, in the lowest part of the drum D ₁ , the gap 20 formed between the two connecting bars 5 connecting the pair of ring bodies 4 of the drum body 10 and the wiring / pipe material A was cut. The material 8 is inserted and fixed to the spoke bar 3 via the material fixing tool 9 having both ends thereof bent. The drum D ₁ is sequentially rotated, and the material 8 held in the gap 20 is inserted between the two connection bars 5 and the wiring / piping material A in the same manner as described above in all the connection bars 5. . As a result, as shown in FIG. 1, the wiring / piping material A no longer rotates idly with respect to the drum body 10, and the wiring / piping material A can be fed out by the rotation of the drum D ₁ . In FIG. 1, the connecting bar 5 on which the bald material 8 is placed is not shown in order to avoid complication of the drawing. Further, with regard mounting operation of the side bar 28, it is also possible to perform the drum D ₁ wiring and piping material A is mounted in a state of being supported on the frame B _1. In any case, since a plurality of side bars 28 are arranged on both sides of the wiring / piping material A mounted in the inserted state outside the drum body 10, Slipping out is prevented.
[0020]
Subsequently, another embodiment of the present invention will be described. In the case where the wiring / pipe material is the information sheath tube A ′, it is often used by pulling out six at the same time, and this embodiment is adapted to this.
