Furthermore, the retaining ring 11 can be freely disassembled into a pair of half rings 12 and 13, or assembled together. 16 is semicircle 1
A connecting piece 17 having a through hole 18 extends from the base of each half ring body 12, 13. The joint portion 19 connected to the above-mentioned fixture 8 has a flanged nut 23 having a flange 22 rotatably inserted into a round hole 21 opened at one end of a joint body 20 bent into a substantially battledore shape. The flanged nut 23 is prevented from slipping outward by the flanges 22, and the flanged nut 23 is prevented from slipping outward by the flanges 22. This prevents the nut 23 from slipping out inward. A headless bolt 26 can be inserted into the female screw hole 25 at the center of the flanged nut 23, if necessary. Here, the female threaded hole 25 has the same diameter as the bolt-like connecting portion 4 of the fixture 8. Further, a connected piece 28 having a through hole 27 is provided at the other end of the joint main body 20. Thus, by sandwiching the connected piece 28 of the joint portion 19 between the connecting pieces 17 of the retaining ring 11, or inserting the connecting piece 17 of the retaining ring 11 between the connected pieces 28 of the joint portion 19, each through hole is inserted. 18 and the connecting bolt 29 inserted through the through hole 27 with the nut 3.
The pipe holding device 3 can be constructed by connecting the retaining ring 11 and the joint portion 19 by tightening the bolt 29 and the joint portion 19. The angle between the two can be freely adjusted within a range of 180 degrees.

However, when constructing it, it is carried out as follows. Although FIG. 3 shows a C-channel steel beam 5 as a frame material for fixing the pipe 10, it is of course possible to use a wooden frame material.
The method is not limited to construction materials or framework materials, and the application location can be freely selected, and what is shown in FIG. 3 is an example of a construction example. First, grasp the screw operation part 1 of the fixture 8 with a tool such as a spanner or box wrench, press the tip of the tapping screw part 2 against the bottom surface of the beam 5, and turn the fixture 8 with the tool to cut the tip of the tapping screw part 2. The tapping screw part 2 is screwed into the beam 5 while making a hole in the beam 5 with a blade 9, and the tapping screw part 2 is screwed into the beam 5 until the screw-in operation part 1 is tightened to the beam 5. As a result, the fixture 8 is firmly fixed to the beam 5. Next, remove the headless bolt 26 from the flanged nut 23 of the joint part 19 separated from the retaining ring 11, turn the flanged nut 23, and insert the bolt-shaped connecting part of the fixture 8 into the flanged nut 23. 4 are screwed together, and the joint portion 19 is connected to the fixture 8 fixed to the beam 5. Furthermore, the retaining ring 11 is opened and the pipe 10 is held in the retaining ring 11, and the retaining ring 11 is closed while retaining the pipe 10.

and the joint part 19 to connect the pipe holding device 3.
Assemble. At this time, the angle of the retaining ring 11 can be freely adjusted along the piping direction of the pipe 10 depending on the inclination with the joint part 19 and the angle between the joint part main body 20 and the flanged nut 23. Furthermore, the height of the retaining ring 11 can be freely adjusted by turning the flanged nut 23 and moving it up and down with respect to the connecting part 4.

The one shown in FIGS. 4 and 5 is another example of the fixture 8, in which a tapping screw part 2 is provided at the tip of a relatively long hexagonal column-shaped screw-in operation part 1, and the screw-in operation part 1 is screwed in from the rear end surface of the screw-in operation part 1. A connecting portion 4 is provided in the shape of a nut or internal thread toward the inside of the operating portion 1. The diameter of this connecting portion 4 is equal to the diameter of the headless bolt 26. As shown in FIG. 6, this fixture 8 is also used to screw the tapping screw part 2 into the beam 5 using a tool, and after fixing the fixture 8, a headless nut is inserted into the flanged nut 23 of the joint part 19. Insert the bolt 26, connect this headless bolt 26 to the nut-shaped connecting part 4 of the fixture 8, and connect the joint part 19 to the fixture 8.
It is now connected to.

In the above embodiment, in order to provide versatility in the structure of the pipe holding device 3, the headless bolt 26 is not used so that the pipe holding device 3 can be applied to both types of fittings 8. It is also possible to use a flanged bolt instead of the nut 23 and use a dedicated pipe holding device 3 in the fixture 8 of FIGS. 4 and 5.
