  Hereinafter, embodiments will be described and embodiments of the present invention will be described. In the second and subsequent embodiments, the same components as those already described are denoted by the same reference numerals, and description thereof is omitted.

[First Embodiment]
First, the first embodiment will be described. The piping system 10 which concerns on this embodiment is shown by FIGS. 1-3. The piping system 10 includes a connection-type header 12 and a mount 13 according to the present embodiment on which the header 12 is placed and the upper side of the header 12 is protected.

  As shown in FIGS. 4 to 6, the header 12 is formed by connecting a plurality of header bases 14, and a connecting portion 41 is formed between the adjacent header bases 14 and the header bases 14. The header base 14 is integrally provided with a branch pipe connecting portion 18 in the main pipe portion 16. A straight flow path 20 is provided inside the main pipe portion 16, and a rising flow path 22 is provided inside the branch pipe connection portion 18.

  The branch pipe connecting portion 18 is provided with a synthetic resin inner cylinder 26 that is inserted into the resin pipe 24 connected to the rising flow path 22, for example, colored in black, on the outer surface of the inner cylinder 26. An O-ring 30 is fitted in the formed circumferential groove 28.

A transparent synthetic resin outer cylinder 32 is disposed on the outer peripheral side of the inner cylinder 26 through a gap into which the resin pipe 24 is inserted. A pipe holding ring 34 having a V-shaped cross section is disposed on the distal end side of the outer cylinder 32, and a cylindrical cap 36 for preventing the pipe holding ring 34 from being detached is attached to the outer cylinder 32. .
In addition, a release ring 38 for releasing the biting of the claw portion of the pipe holding ring 34 is mounted inside the cap 36.

  When the resin pipe 24 is inserted between the inner cylinder 26 and the outer cylinder 32, the inner peripheral side end of the pipe holding ring 34 is caught on the outer peripheral surface of the resin pipe 24 to prevent the resin pipe 24 from coming off. Thus, the O-ring 30 is in close contact with the inner peripheral surface of the resin pipe 24 for sealing (so-called inner surface sealing). The resin pipe 24 is rotatable while being inserted between the inner cylinder 26 and the outer cylinder 32.

  When the release ring 38 is pushed in and pressed against the pipe holding ring 34, the taper portion of the release ring 38 slides on the inclined surface on the inner peripheral side of the pipe holding ring 34, and the inner diameter of the release ring 34 is increased to increase the resin pipe. The hook with 24 is released, and the resin pipe 24 can be pulled out.

  One end portion of the main pipe portion 16 has the same structure as that of the branch pipe connecting portion 18, and the other end portion is a cylindrical body portion 40 having the same inner and outer diameter as the resin pipe 24. And the outer cylinder 32 can be inserted.

  Therefore, by inserting the cylindrical portion 40 of the main pipe portion 16 of the header base body 14 between the inner and outer cylinders of the main pipe portion 16 of another adjacent header base body 14, as shown in FIG. The headers 14 can be connected to each other so that each header base 14 can be rotated.

  1, 2, and 4, all the branch pipe connection portions 18 are directed in the same direction. However, for example, as shown in FIG. 3, by rotating any one of the header bases 14, The branch pipe connection 18 can be directed in another direction.

As shown in FIGS. 1 to 3, the gantry 13 is provided with a long mounting portion 50 on which the header 12 to be laid is placed at the center position in the width direction. Placed on the top. The gantry 13 has long side portions 52 that are continuous on both sides of the placement portion 50 in the width direction. In the side portion 52, a pore portion 54 for fixing a side band 56 described later is formed at a predetermined position. 1 to 3, the pores 54 formed in the side portion 52 that can be seen on the near side are illustrated, but the longitudinal side portion on the opposite side (the far side) from the near side is similarly thinned. A hole is formed.
Note that the pores 54 may not be formed. In this case, in order to fix the side band 56, an operation such as screwing directly to the slab is performed.

  Further, the gantry 13 is provided with a side band 56 that fixes the header 12 to the placement unit 50. Then, as a protective cover that can be opened and closed on the upper side of the header 12, that is, a position that protects the header 12 with strength on the upper side of the header, and a position that is retracted from the rotation locus R (see FIG. 3) of the branch pipe connecting portion 18. As the protective cover that can be moved in the above, plate members 58P and 58Q extending from the side band upper portion 56U to both sides in the mounting portion longitudinal direction U are provided. The plate members 58P and 58Q are connected to each other on the base side so as to be rotatable by hinges 60 on both sides of the side band upper portion 56U, and are folded in the upward direction H (see FIGS. 2 and 3). It can be switched to a state (see FIG. 1) along the placement portion longitudinal direction U.

  The side band 56 is U-shaped when viewed from the mounting portion longitudinal direction U, and a leg portion 62 extending outward in the width direction is formed at the lower end portion. The leg portion 62 is formed with a circular hole portion 64 for fixing with a rivet, a bolt or the like so that the leg portion 62 can be fixed to the pore portion 54. 1 to 3, the front side leg portion 62 of the side band 56 is illustrated, but a circular hole portion is similarly formed in the leg portion on the opposite side (far side).

  In the present embodiment, after the header 12 connected to the plurality of header bases 14 is placed on the placement unit 50, the header 12 is fixed to a predetermined position of the placement unit 50 by the side band 56. As a result, the upper side of the header 12 is protected by the plate members 58P and 58Q. Therefore, even if an operator accidentally steps from above the laid header 12 or an operator accidentally drops a transported object from above the header 12, the plate members 58P and 58Q protect the header 12. Therefore, there is no possibility that the header 12 is damaged.

When it is necessary to move the plate materials (protective covers) 58P and 58Q to the position retracted from the rotation trajectory R of the branch pipe connection portion 18, the plate materials 58P and 58Q are respectively bent in the upward direction H from the root side. Thus, the plate members 58P and 58Q are opened with respect to the header 12. When this is necessary, for example, as shown in FIG. 3, one of the branch pipe connecting portions 18 is connected in the upward direction H or the reverse direction by rotating any one of the header bases 14. This is when the need arises.
Further, the headers 12 are protected by the plate members 58P and 58Q on the upper side of the header by returning the plate members 58P and 58Q to a position along the placement portion longitudinal direction U.

  As described above, in this embodiment, the plate members 58P and 58Q are positioned on the upper side of the header 12, so that the header 12 can be prevented from being damaged due to pressing or impact from above. Even if the plate members 58P and 58Q are provided, the plate members 58P and 58Q can be moved to a position retracted from the rotation trajectory R of the branch pipe connecting portion 18 to switch the positions.

Further, instead of the plate members 58P and 58Q, as shown in FIGS. 7 and 8, a plate member 78 fixed on the upper side of the side band 56 by a fixture 77 may be provided. In this case, for example, the plate member 78 includes a curved flat plate-shaped central portion 78C along the side band upper portion 56U (see FIG. 1), and a wing portion 78P rotatably connected to both sides of the central portion 78C by hinges 68. 78Q. And the attachment 77 is made into the curved flat plate shape along the center part 78C, and it is set as the structure fixed to the side band 56 by the side band short side seen from the plane.
As a result, even if the plate member 78 is attached by the attachment 77 after the side band 56 is attached, the wings 78P and 78Q are bent upward H (see FIG. 8) and the header 12 is protected on the upper side of the header. It is possible to switch to the state (see FIG. 7).
