Description

[Technical Field]

[0001] The present disclosure relates to a pipe support device and a pipe support device system for supporting pipes with a car stop function installed on roads, sidewalks, parks, etc., or support pipes used at construction sites. [Background technology]

[0002] Pipes with a bollard function have traditionally been installed on roads, sidewalks, parks, etc. to prevent vehicles from entering. Support pipes are also installed at construction sites for workers. Furthermore, depending on the installation environment (facility entrances and exits), it may be necessary to install pipes that can be removed and attached. In such cases, pipes are generally installed by burying the pipe, but in some cases, such as retrofitting or when it is not possible to dig deep into the ground, shallow installation is required.

[0003] Such pipes are installed above ground using a pipe support device, in which the pipe is either rotated and clamped to the pipe support device or is attached by sliding it laterally to the pipe support device. [Prior art documents] [Patent documents]

[0005] However, some of the above-mentioned pipes, such as U-shaped pipes, cannot be tightened by rotating them. Also, some pipes have a predetermined rotation angle and installation position, so they cannot be rotated or slid when installed.

[0006] The present disclosure has been made in consideration of these points, and aims to provide a pipe support device and a pipe support device system that can easily and stably install a pipe on the ground surface without rotating or sliding the pipe. [Means for solving the problem]

[0007] The present disclosure relates to a pipe support device comprising: a base having a base body; a pedestal placed on the base; a pipe support part connected to the pedestal and supporting a pipe; a retaining plate interposed between the pedestal and the pipe support part; and a rotating body having an outer peripheral plate and fastened to the outer peripheral surface of the base body of the base, wherein the pedestal is fixed between the retaining plate of the rotating body and the base body of the base by fastening the rotating body to the base.

[0008] The present disclosure relates to a pipe support device in which a pair of outer inclined plates are provided on the outer peripheral surface of the base body of the base, and a pair of inner inclined plates that engage with the outer inclined plates are provided on the inner peripheral surface of the outer peripheral plate of the rotating body.

[0009] The present disclosure relates to a pipe support device in which each inner inclined plate of the outer peripheral plate is inserted between a pair of outer inclined plates of the base, and the rotating body is rotated, so that each inner inclined plate abuts against the corresponding outer inclined plate, and the rotating body is tightened to the outer peripheral surface of the base, thereby fixing the base between the retaining plate of the rotating body and the base of the base.

[0010] The present disclosure relates to a pipe support device in which, before the rotating body is tightened, the pipe support portion and the base are movable horizontally relative to the retaining plate, and by tightening the rotating body, the base is fixed between the retaining plate of the rotating body and the base body of the base.

[0011] The present disclosure is a pipe support device system comprising the above-described pipe support device and a rod-shaped pipe extending linearly in the vertical direction, the lower end of the rod-shaped pipe being supported by the pipe support device.

[0012] The present disclosure is a pipe support device system comprising a pair of the above-described pipe support devices and a U-shaped pipe, with each end of the U-shaped pipe supported by a corresponding one of the pipe support devices. [Effects of the Invention]

[0013] As described above, according to the present disclosure, a pipe can be easily installed on the ground without rotating or sliding the pipe. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] First Embodiment Hereinafter, a first embodiment of the present disclosure will be described with reference to the drawings.

[0016] 1 to 13 are diagrams illustrating a first embodiment of the present disclosure.

[0017] As shown in FIGS. 1 to 3, a pipe support device 1 according to the present disclosure supports, for example, a U-shaped pipe 2 (see FIGS. 6 and 7) having a car stop function on the ground G (see FIG. 8).

[0018] The U-shaped pipe 2 supported by the pipe support device in this way is installed on roads, sidewalks, parks, etc., and functions as a car stopper.

[0019] In this specification, when the pipe support device 1 is placed as shown in Figures 1 to 3, the up-down direction in Figures 1 to 3 is the vertical direction, and the lateral direction perpendicular to this vertical direction is the horizontal direction.

[0020] The pipe support device 1 is installed on the ground surface G and comprises a base 10 having a base body 11, a pedestal 20 placed on the base 10, a pipe support part 40 connected to the pedestal 20 by a connecting bolt 25 and supporting one end 2A of the U-shaped pipe 2, and a rotating body 30 having a retaining plate 31 interposed between the pedestal 20 and the pipe support part 40 and fastened to the outer peripheral surface of the base body 11 of the base.

[0021] Of these, the base 10 has a support plate 13 that is placed on the ground surface G, and the base body 11 is made of a cylindrical body that is placed on this support plate 13.

[0022] The base 10 will now be further described with reference to Figures 8 to 10C.

[0023] First, a post-installed anchor 3 having an internal thread is installed in a sufficiently strong ground surface G, such as concrete 5 installed on pebbles 6. Then, a bolt 17, which will be described later, is inserted into this post-installed anchor 3.

[0024] As shown in Figures 10A to 10C, the base 10 has a support plate 13 placed on the ground surface G and a base body 11 consisting of a cylindrical body provided on the support plate 13, and a pair of outer inclined plates 12, 12 are provided on the outer peripheral surface of the base body 11.

[0025] 10A to 10C, FIG. 10A is a perspective view showing the base 10, FIG. 10B is a plan view showing the base 10, and FIG. 10C is a bottom view showing the base 10. In FIG.

[0026] As shown in Figure 10B, each outer inclined plate 12, 12 provided on the outer peripheral surface of the base 11 is arranged at a circumferential angle of approximately 90° on the outer peripheral surface of the base 11, and a cutout portion 14 where no outer inclined plate 12 is formed is formed between each outer inclined plate 12, 12.

[0027] Furthermore, support plate 13 of base 10 is provided with bolt holes 15 into which the above-mentioned bolts 17 are inserted, and base 10 is fixed to the ground surface G by tightening bolts 17 inserted into bolt holes 15 of support plate 13 into post-installed anchors 3. Bolts 17 tightened into post-installed anchors 3 are covered with bolt covers 16 so as not to be exposed to the outside. Furthermore, base body 11 of base 10 is provided with a pair of recesses 18 that engage with a pair of protrusions 28 formed on the bottom surface of base body 20A of pedestal 20, which will be described later.

[0028] Next, the base 20 will be described with reference to Figures 11A to 11C. Figure 11A is a perspective view showing the base 20, Figure 11B is a plan view showing the base 20, and Figure 11C is a bottom view showing the base 20.

[0029] The base 20 has a disk-shaped base main body 20A, a small portion 20B provided on the base main body 20A, and a pair of circumferential protrusions 21 that protrude radially outward from the outer surface of the base main body 20A and extend circumferentially. On the outer surface of the base main body 20A, cutout portions 22 are formed between the circumferential protrusions 21, where no circumferential protrusions 21 are formed. In addition, on the outer surface of the small portion 20B, a pair of circumferential protrusions 23 are provided that protrude radially outward and extend circumferentially, and a cutout portion 24 is formed between the circumferential protrusions 23, where no circumferential protrusions 23 are formed.

[0030] 11B, the small-shaped portion 20B has an outer edge that is smaller than the outer edge of the base body 20A. A bolt hole 27 is provided through the base body 20A and the small-shaped portion 20B. Furthermore, a pair of protrusions 28 is provided on the bottom surface of the base body 20A at positions corresponding to the pair of recesses 18 provided on the base 11. The pair of protrusions 28 provided on the base body 20A of the base 20 are engaged with the pair of recesses 18 provided on the base body 11 of the base 10. This allows the approximate rotation direction of the base 20 and the pipe support 40 connected to the base 20 relative to the base 10 to be determined. The pair of recesses 18 on the base 11 and the pair of protrusions 28 on the base body 20A are not necessarily required. The base 20 and the pipe support 40 connected to the base 20 may be configured to be freely rotatable to any rotational position relative to the base 10 before the rotating body 30 is fastened.

[0031] Next, the rotating body 30 will be described with reference to Figures 12A to 12C. Figure 12A is a perspective view showing the rotating body 30, Figure 12B is a plan view showing the rotating body 30, and Figure 12C is a bottom view showing the rotating body.

[0032] The rotor 30 has a retaining plate 31 interposed between the base 20 and the pipe support portion 40, and a cylindrical outer peripheral plate 33 connected to the retaining plate 31. A pair of inner inclined plates 32 that engage with the pair of outer inclined plates 12 of the base 10 is provided on the inner peripheral surface of the outer peripheral plate 33. The retaining plate 31 of the rotor 30 is ring-shaped, and the small portion 20B of the base 20 is fitted into the ring-shaped retaining plate 31. An inner peripheral surface of the ring-shaped retaining plate 31 is provided with an inner protrusion 35 that engages with the circumferential protrusion 23 of the small portion 20B. Before the rotor 30 is tightened (see FIG. 4), the inner protrusion 35 of the rotor 30 abuts against the circumferential protrusion 23 of the small portion 20B, thereby determining the rotational position of the rotor 30 before tightening. That is, by rotating the rotor 30 in the loosening direction (counterclockwise), the inner protrusion 35 of the rotor 30 comes into contact with the circumferential protrusion 23 of the small-shaped portion 20B, and the rotor 30 cannot be rotated further in the loosening direction. Therefore, the rotor 30 can only rotate in the tightening direction (clockwise). Then, by tightening the rotor 30, the inner protrusion 35 of the rotor 30 rotates along the cutout portion 24 of the small-shaped portion 20B.

[0033] As shown in Figure 12C, each inner inclined plate 32 provided on the inner surface of the outer plate 33 is arranged at a circumferential angle of approximately 90° on the inner surface of the outer plate 33, and a cutout portion 34 where no inner inclined plate 32 is formed is formed between each inner inclined plate 32, 32.

[0034] Then, by fitting the outer peripheral plate 33 of the rotating body 30 onto the base 11 of the base 10 on the outside and rotating the rotating body 30, the inner inclined plate 32 of the outer peripheral plate 33 engages with the outer inclined plate 12 of the base 11, the rotating body 30 is tightened to the outer peripheral surface of the base 11, and the outer peripheral plate 33 of the rotating body 30 is fixed to the base 11 of the base 10.

[0035] When fitting the outer peripheral plate 33 of the rotating body 30 outside the base body 11 of the base 10, the positions of the base 10 and the rotating body 30 are aligned so that the inner inclined plate 32 of the outer peripheral plate 33 is positioned corresponding to the cutout portion 14 between the outer inclined plates 12 of the base body 11. Thereafter, by rotating the rotating body 30 in the tightening direction (clockwise), the inner inclined plate 32 of the outer peripheral plate 33 engages with the outer inclined plate 12 of the base body 11, and the rotating body 30 is tightened toward the base 10. As a result, the base body 20A of the pedestal 20 is sandwiched and fixed between the base body 11 of the base 10 and the holding plate 31 of the rotating body 30.

[0036] As described above, the pedestal 20 is connected to the pipe support part 40, which supports the pipe 2, by the connecting bolt 25. Therefore, the pedestal body 20A of the pedestal 20 is fixed between the base body 11 of the base 10 and the retaining plate 31 of the rotating body 30, and the pipe support part 40 is also firmly fixed to the base 10.

[0037] In this embodiment, each outer inclined plate 12 of the base 11 and each inner inclined plate 32 of the outer peripheral plate 33 are arranged at a circumferential angle of approximately 90° along the circumferential direction and have inclined surfaces that are inclined toward each other. Then, by engaging the outer inclined plate 12 with the inner inclined plate 32 with each other and rotating the rotating body 30 by approximately 90° relative to the base 10, the rotating body 30 is fastened to the base 10 side, and as a result, the base body 20A of the pedestal 20 is sandwiched between the base 11 of the base 10 and the holding plate 31 of the rotating body 30, and the rotation of the rotating body 30 is stopped.

[0038] Next, the pipe support portion 40 will be described with reference to FIGS. 13A to 13D.

[0039] Here, Figure 13A is an oblique view showing the pipe support part 40, Figure 13B is a plan view showing the pipe support part 40, Figure 13C is a bottom view showing the pipe support part 40, and Figure 13D is a side cross-sectional view showing the state in which the pipe support part 40 and the base 20 are connected.

[0040] 13A to 13D, pipe support part 40 has a cylindrical body 41 that fits over one end 2A of pipe 2 and supports this pipe 2, and a flange part 42 connected to cylindrical body 41. Furthermore, flange part 42 is provided with bolt holes 47 at positions corresponding to bolt holes 27 of base 20. Furthermore, a bottom plate 2a is fixed to one end 2A of pipe 2 in advance.

[0041] One end 2A of the pipe 2 is fitted into the cylindrical body 41 of the pipe support 40 configured as described above, and the pipe support 40 with the fitted one end 2A of the pipe 2 is placed on the base 20 via the retaining plate 31 of the rotor 30. Then, a connecting bolt 25 is passed through the bolt hole 27 of the base 20 and the bolt hole 47 of the pipe support 40, and this connecting bolt 25 is further engaged with a female thread (not shown) in the bottom plate 2a provided at the one end 2A of the pipe 2. Next, the connecting bolt 25 is tightened into the female thread of the bottom plate 2a provided at the pipe 2. In this way, the connecting bolt 25 secures the pipe support 40 to the base 20, and simultaneously secures the one end 2A of the pipe 2 to the pipe support 40 (see FIG. 13D). It is not necessarily necessary to fix the pipe support part 40, the base 20 and one end 2A of the pipe 2 as a single unit using the connecting bolt 25. For example, the one end 2A of the pipe 2 may be fixed to the pipe support part 40 by welding in advance, and only the pipe support part 40 and the base 20 may be fixed using the connecting bolt 25.

[0042] 13D, as described above, the holding plate 31 of the rotating body 30 is interposed on the outer periphery of the small portion 20B of the base 20. The holding plate 31 of the rotating body 30 is located between the base main body 20A of the base 20 and the flange portion 42 of the pipe support portion 40, and is disposed with a certain vertical gap between the base main body 20A and the flange portion 42. Therefore, the holding plate 31 of the rotating body 30 is movable horizontally between the base main body 20A and the flange portion 42 (see FIG. 13D).

[0043] Next, the operation of this embodiment configured as described above will be explained. First, an example will be shown in which a U-shaped pipe 2 having a car stop function is supported by a pair of pipe support devices 1.

[0044] First, a post-installed anchor 3 having a female thread is attached to a ground surface G of sufficiently strong ground, such as concrete 5 laid on pebbles 6.

[0045] Next, a support plate 13 is placed on the post-installed anchors 3 in the concrete 5, and bolts 17 are inserted into bolt holes 15 in the support plate 13. Next, the bolts 17 are tightened against the post-installed anchors 3, thereby fixing the base 10 of the support device 1 for one pipe to the ground surface G. Thereafter, the bolts 17 are covered with bolt covers 16.

[0046] During this time, a U-shaped pipe 2 having a car stop function is prepared in advance, and one end 2A of the U-shaped pipe 2 is fitted into the cylindrical body 41 of the corresponding pipe support part 40, and in this way one end 2A of the U-shaped pipe 2 is supported by the pipe support part 40 of the pipe support device 1.

[0047] Next, the base 20, the rotor 30, and the pipe support part 40 supporting one end 2A of the U-shaped pipe 2 are overlapped. After that, the connecting bolt 25 is passed through the base 20 and the pipe support part 40 from the base 20 side, and the connecting bolt 25 is engaged with the female thread of the bottom plate 2a provided at one end 2A of the pipe 2 and tightened. By tightening the connecting bolt 25 in this manner, the one end 2A of the pipe 2, the pipe support part 40, and the base 20 are connected to one another with the retaining plate 31 of the rotor 30 interposed between the pipe support part 40 and the base 20.

[0048] Next, the rotor 30 is brought close to the base 10 fixed to the ground surface G, and the outer peripheral plate 33 of the rotor 30 is fitted onto the outside of the base body 11 of the base 10 (see FIGS. 2 and 3).

[0049] In this case, the holding plate 31 of the rotating body 30 is movable horizontally between the base body 20A and the flange portion 42, so that the pipe support portion 40 and base 20 that hold the pipe 2 relative to the rotating body 30 can move horizontally.

[0050] Therefore, even if the U-shaped pipe 2 is slightly warped or deformed, when the rotor 30 is brought close to the base 10 and the outer plate 33 of the rotor 30 is fitted onto the outside of the base body 11 of the base 10, the pipe support part 40 that supports one end 2A of the pipe 2 moves horizontally relative to the rotor 30, thereby absorbing the warp and deformation of the U-shaped pipe 2. Therefore, the rotor 30 can be fitted onto the outside of the base body 11 of the base 10 easily and reliably.

[0051] Next, the operation of fitting and rotating the rotating body 30 into the base 10 will be further explained with reference to Figures 4 and 5. When fitting the rotating body 30 into the base 10, the position mark M1 provided on the support plate 13 of the base 10, the position marks M2 provided on the holding plate 31 and outer peripheral plate 33 of the rotating body 30, and the position mark M3 provided on the flange 42 of the pipe support part 40 are aligned with one another (see Figure 4).

[0052] 4 and 5 are diagrams showing the action of fitting the rotating body 30 into the base 10 and rotating it, and for convenience, the pipe 2 has been removed from the pipe support part 40.

[0053] 4 and 5, the position mark M1 of the base 10 is provided corresponding to the cutout portion 14 between the outer inclined plates 12, 12 provided on the base body of the base 10 (see FIG. 1), the position mark M2 of the rotating body 30 is provided corresponding to the inner inclined plate 32 provided on the outer peripheral plate 33 (see FIGS. 1 and 12C), and the position mark M3 of the pipe support portion 40 is provided corresponding to the cutout portion 22 between the circumferential protrusions 21 provided on the base body 20A (see FIG. 1).

[0054] In this case, a pair of protrusions 28 on the base body 20A of the base 20 engage with a pair of recesses 18 on the base body 11 of the base 10, roughly determining the rotational position of the base 20 relative to the base 10. As a result, the position mark M1 on the base 10 corresponds to the position mark M3 on the pipe support part 40 connected to the base 20. Furthermore, by rotating the rotating body 30 in the loosening direction (counterclockwise), the inner protrusion 35 of the rotating body 30 abuts against the circumferential protrusion 23 of the small portion 20B, determining the rotational position of the rotating body 30, and the position mark M2 on the rotating body 30 coincides with the position mark M1 on the base 10 and the position mark M3 on the pipe support part 40. By aligning the position marks M1, M2, and M3 in this way, the inner inclined plate 32 of the outer peripheral plate 33 of the rotating body 30 corresponds to the cutout portion 14 between the outer inclined plates 12 of the base body 11. In this way, the rotating body 30 can be securely fitted into the base body 11 of the base 10. Then, by rotating the rotating body 30 clockwise relative to the base 10 and tightening it, the inner inclined plate 32 of the outer peripheral plate 33 engages with the outer inclined plate 12 of the base body 11, and the rotating body 30 is tightened toward the base 10 (see Figure 5).

[0055] As a result, the base body 20A of the base 20 is sandwiched and fixed between the base body 11 of the base 10 and the holding plate 31 of the rotating body 30.

[0056] In this case, as described above, the pedestal 20 is connected to the pipe support part 40, which supports one end 2A of the pipe 2, and to one end 2A of the pipe 2 by the connecting bolt 25. Therefore, the pedestal body 20A of the pedestal 20 is fixed between the base body 11 of the base 10 and the retaining plate 31 of the rotating body 30, and the pipe 2 and the pipe support part 40 are also firmly fixed to the base 10.

[0057] As shown in Figures 4 and 5, the base body 20A of the pedestal 20 can be clamped between the base body 11 of the base 10 and the retaining plate 31 of the rotating body 30 simply by rotating the rotating body by 90° relative to the base 10, at which point the rotation of the rotating body 30 stops (see Figure 5).

[0058] In this case, as shown in FIG. 5, the position marks M1 and M3 are aligned, but the position mark M2 is spaced apart from the position marks M1 and M3 by approximately 90° in the circumferential direction.

[0059] As shown in Figure 5, when the position mark M2 of the rotating body 30 moves away from the position mark M1 of the base 10 and the position mark M3 of the pipe support portion 40 in the circumferential direction, the opening 35A provided in the rotating body 30 reaches the vicinity of the position mark M1 of the base 10 and the position mark M3 of the pipe support portion 40.

[0060] In this case, the position of the opening 35A of the rotor 30 corresponds to the cutout 34 between the inner inclined plates 32 provided on the outer peripheral plate 33 of the rotor 30 because the rotor 30 rotates by approximately 90 degrees.

[0061] In Figure 5, after tightening and fixing the rotating body 30 to the base 10, the hook 38a of the padlock 38 is inserted through the opening 35A corresponding to the cutout portion 34 between the inner inclined plates 32, and the hook 38a of this padlock 38 is hooked onto the locking portion 35a inside the opening 35A.

[0062] As described above, the opening 35A of the rotor 30 is located at a position corresponding to the notch 34 between the inner inclined plates 32, and the opening 35A is located near the position mark M1 indicating the notch 14 between the outer inclined plates 12 of the base 10.

[0063] Therefore, the hook 38a of the padlock 38 inserted into the opening 35A fits into the notch 14 between the outer inclined plates 12 of the base 10. As a result, when the rotating body 30 is rotated counterclockwise to loosen it from the base 10, the hook 38a of the padlock 38 comes into contact with the outer inclined plate 12 of the base 10, preventing the rotating body 30 from rotating.

[0064] In this way, the hook 38a of the padlock 38 can prevent the rotating body 30 from being loosened from the base 10, and can prevent the rotating body 30 from being removed from the base 10 in advance.

[0065] In this way, as shown in FIGS. 6 and 7, one end 2A of the U-shaped pipe 2 can be easily and reliably supported by the pipe support device 1.

[0066] As shown in Figures 6 and 7, the other end 2B of the U-shaped pipe 2 can also be supported by the support device 1 for the other pipe in the same way that one end 2A of the pipe 2 is supported by the support device 1 for the pipe.

[0067] As described above, by supporting one end 2A and the other end 2B of the U-shaped pipe 2 with the pipe support device 1, a pair of pipe support devices 1 and the U-shaped pipe 2 form a pipe support device system 1A.

[0068] As described above, according to this embodiment, when installing the U-shaped pipe 2 having a car stop function on the ground G, there is no need to rotate or slide the pipe 2 horizontally. One end 2A and the other end 2B of the pipe 2 are attached to the pipe support part 40, and the rotating body 30, which is connected to the pipe support part 40 in advance, is fitted into the corresponding base part 10 and rotated. In this way, one end 2A and the other end 2B of the pipe 2 can be easily and reliably installed on the ground G via the pipe support device 1.

[0069] Furthermore, even if the U-shaped pipe 2 is distorted or deformed, in each pipe support device 1, the pipe support part 40 and the base 20 are movable horizontally relative to the holding plate 31 of the rotating body 30, so that the pipe support part 40 and the base 20 can move horizontally relative to the holding plate 31 of the rotating body 30, thereby absorbing the distortion or deformation of the shape of the pipe 2. Therefore, there is no problem with fitting the rotating body 30 onto the outside of the base 10 or subsequently rotating the rotating body 30 relative to the base 10.

[0070] <Second embodiment> Next, a second embodiment of the present disclosure will be described with reference to FIGS.

[0071] The second embodiment shown in Figures 14 and 15 has a rod-shaped pipe 52 that has a car stop function and extends linearly in the vertical direction, instead of the U-shaped pipe 2, supported by a pipe support device 1, and the other configurations are approximately the same as those of the first embodiment shown in Figures 1 to 13D.

[0072] In the second embodiment shown in FIGS. 14 and 15, the same parts as those in the first embodiment shown in FIGS. 1 to 13D are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0073] 14, one end 52A of a rod-shaped pipe 52 is attached to the pipe support part 40 of the pipe support device 1. The base 20, the rotating body 30, and the pipe support part 40 to which the one end 52A of the rod-shaped pipe 52 is attached are overlapped with each other, and the one end 52A of the rod-shaped pipe 52 and the pipe support part 40 are attached to the base 20 via the holding plate 31 of the rotating body 30 by a connecting bolt 25 (see FIG. 13D).

[0074] Next, the rotating body 30 connected to one end 52A of the rod-shaped pipe 52, the pipe support part 40, and the base 20 is fitted into the base 10 of the pipe support device 1 and rotated. In this way, the one end 52A of the rod-shaped pipe 52 can be placed on the ground G via the pipe support device 1 (see FIG. 15).

[0075] 14 and 15, a pipe support device system 1A is configured by a pipe support device 1 and a rod-shaped pipe 52.

[0076] Next, as shown in FIG. 15, a plurality of chains 54 are successively attached to the rod-shaped pipes 52 via locking rings 53, and these chains 54 are connected to adjacent rod-shaped pipes 52 for use.

[0077] Therefore, in the second embodiment, the circumferential position of the rod-shaped pipe 52 is determined by the chain 54.

[0078] As described above, according to this embodiment, when installing rod-shaped pipe 52 having a car stop function on the ground G, there is no need to rotate or slide pipe 52 horizontally. One end 52A of pipe 52 is attached to pipe support part 40, and rotating body 30, which is connected to pipe support part 40 in advance, is fitted into the corresponding base part 10 and rotated (see FIG. 14). This allows one end 52A of pipe 52 to be easily and reliably installed on the ground G via pipe support device 1 (see FIG. 15).

[0079] When installing the rod-shaped pipe 52 on the ground G in this way, there is no need to rotate or slide the pipe 52 horizontally, so even when using the rod-shaped pipe 52 to provide a continuous chain 54 between adjacent rod-shaped pipes 52, the rod-shaped pipe 52 can be installed on the ground G via the pipe support device 1 while maintaining the circumferential position of the pipe 52 without rotating the pipe 52. Therefore, the chains 54 can be easily installed on the rod-shaped pipe 52 in a straight line.

[0080] 14 and 15, an example has been described in which the rod-shaped pipe 52 has a car stop function, but the rod-shaped pipe 52 is not limited to this and may be a support pipe used at a construction site. Furthermore, the rod-shaped pipe 52 may be a detachable pipe provided according to the installation environment (facility entrance / exit). [Explanation of symbols]
