Description

[Technical Field]

[0001] The present invention relates to a pipe support fitting for supporting and holding pipes. [Background technology]

[0002] When installing pipes and long objects such as electrical conduits (PF pipes, etc.) and cables on floors or walls, channel bases and pipe support fittings have traditionally been used (see Non-Patent Document 1). The channel base is a long object with a roughly U-shaped cross section, with opposing lips formed on both end edges.

[0003] On the other hand, the pipe support fitting includes two support plates of approximately the same shape. That is, the support plate is a substantially rectangular plate material, and lip insertion portions for inserting the lip portions of the channel base are formed on both side edges of one end of the support plate, and the other end is bent into an arc to form a flange portion at the tip. This flange portion is formed so as to be positioned approximately vertically above the pipe when the pipe is clamped between the two support plates as described below. Furthermore, the flange portion of one support plate is formed with a bolt insertion hole for inserting a connecting bolt, and the flange portion of the other support plate is formed with a screw hole into which the connecting bolt screws.

[0004] The pipes are then placed on the opening side of the channel base so as to be approximately perpendicular to the channel base, and the two support plates of the pipe support bracket are arranged on the channel base so as to sandwich the pipes. That is, the support plate is tilted and one end is inserted into the opening of the channel base, and the support plate is then positioned so as to be approximately perpendicular to the longitudinal direction of the channel base, allowing the lip portions of the channel base to be inserted into both lip insertion portions. Next, a connecting bolt is inserted into the bolt insertion hole of one support plate, and the connecting bolt is tightened into the screw hole of the other support plate. In this way, the two support plates are connected to the channel base, and the pipes are sandwiched and supported by the two support plates. [Prior art documents] [Patent documents]

[0005] [Non-Patent Document 1] "Marui Electric Equipment Parts General Catalog 2020 No.2" published by Marui Sangyo Co., Ltd., p.212 Summary of the Invention [Problem to be solved by the invention]

[0006] However, if the two support plates of a piping support fitting are transported to the construction site separately, there is a risk of losing the support plates or connecting bolts, so the piping support fitting is transported to the construction site with the two support plates connected by the connecting bolts. However, as described above, when installing the piping support fitting in the channel base, the support plate must be tilted and one end inserted into the opening in the channel base, and the lip portion must be inserted into the lip insertion portion, and if the two support plates remain connected, this cannot be done because the support plate will interfere with the piping or the channel base.

[0007] This required removing the connecting bolts to separate the two support plates, placing each plate on its own channel base, and then reconnecting the two support plates with the connecting bolts, which was time-consuming and labor-intensive. Particularly when installing a large number of pipe support fittings, this not only required a great deal of time and labor, but also placed a heavy burden on the workers.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a pipe support fitting that can be installed on a channel base even when two support plates remain connected by connecting bolts. [Means for solving the problem]

The present invention is characterized in that a pipe support fitting is used that has a connecting bolt that connects the first support plate and the second support plate, and an avoidance portion that prevents the second support plate from interfering with the pipes is provided in the form of a notch from the second lip insertion portion of at least one side edge of the second support plate toward the second flange portion, and the first support plate and the second support plate are connected with the connecting bolt, and with the lip portion of the channel base inserted into the first lip insertion portion of the first support plate, the lip portion of the channel base is inserted into the second lip insertion portion of the second support plate while avoiding the second support plate from interfering with the pipes via the avoidance portion, thereby supporting the pipes on the channel base. [Effects of the Invention]

[0016] Claim 1, 5 and 11 According to the invention described in Similar Since the avoidance portion for avoiding interference between the first and second support plates is provided on the side edge of the second support plate, it is possible to install the piping support fitting on the channel base even when the two support plates are connected with the connecting bolt. In other words, with the two support plates connected with the connecting bolt and the lip portion of the channel base inserted into the first lip insertion portion of the first support plate, Similar By inserting the lip portion of the channel base into the second lip insertion portion of the second support plate while avoiding interference with the avoidance portion, it becomes possible to arrange the piping support fittings on the channel base even while the two support plates are connected with the connecting bolt.

[0017] This eliminates the need to remove the connecting bolts and separate the two support plates, as was previously the case, reducing the effort and time required to install pipe support fittings. In particular, when installing a large number of pipe support fittings, not only can this significantly reduce the effort and time required, but it also significantly reduces the burden on workers. In addition, because there is no need to separate the two support plates, there is no risk of losing the support plates or connecting bolts.

[0018] Claim 7According to the invention described in (1), the first flange and the second flange are formed so that their surfaces are positioned obliquely with respect to a reference plane that is substantially perpendicular to the longitudinal direction of the channel base and extends substantially above the opening. In other words, the connecting bolt is disposed so as to extend obliquely with respect to the channel base, and the second support plate is positioned on the channel base side (the lower side of the piping), making it easy to insert the lip of the channel base into the second lip insertion portion of the second support plate. As a result, the piping support fitting can be easily and quickly disposed on the channel base.

[0019] Furthermore, because the connecting bolts extend diagonally relative to the channel base, even when multiple pipes are closely spaced on the channel base (when the distance between adjacent pipe support fittings is short), it is possible to tighten the connecting bolts using an electric screwdriver, etc. In other words, it is possible to arrange multiple pipes with narrow adjacent spacing.

[0020] Claim 8 According to the invention described above, the second support plate is composed only of a second flat plate portion having an approximately flat plate shape and a second flange portion, so that the structure is simple and it is possible to reduce manufacturing costs, including mold costs.

[0021] Claim 9 According to the invention described in (1), the leading edge of the second support plate on the second lip insertion portion side is formed in a substantially arc shape, so that the second support plate does not interfere with the piping or the channel base, and it is easy to insert the lip portion of the channel base into the second lip insertion portion of the second support plate. As a result, it is possible to easily and quickly arrange the piping support fitting on the channel base.

[0022] Claim 2 According to the invention described in the document, an avoidance portion is formed in the shape of a notch that spans the second flange portion. In other words, since the avoidance portion is formed on the opposite side of the second lip insertion portion, it is possible to insert the lip portion into the second lip insertion portion by pushing the avoidance portion toward the piping, thereby avoiding interference with the channel base, etc.

[0023] Claim 3 According to the invention described in the above, the avoidance portion is formed in the shape of a notch that overlaps the second flange portion side of the second lip insertion portion and bites into the center of the second support plate further than the second lip insertion portion. Therefore, by inserting the lip portion up to the avoidance portion and avoiding interference with the channel base, etc., it becomes possible to insert the lip portion into the second lip insertion portion.

[0024] Claim 5 According to the invention described in the above, a part of the side edge of the second support plate is bent to form an avoidance portion. In other words, since the avoidance portion is formed by bending rather than by cutting out, it is possible to increase the strength and rigidity of the second support plate.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The present invention will be described below based on the illustrated embodiments.

[0027] (Embodiment 1) Fig. 1 is a first perspective view (a) and a second perspective view (b) showing a piping support fitting 1 according to this embodiment, and Fig. 2 is a perspective view showing a state in which an electric conduit L is supported by the piping support fitting 1. This piping support fitting 1 is a fitting for supporting and holding piping arranged on a channel base C, and in this embodiment, the case in which the piping is an electric conduit L will be mainly described, but the piping may also be a cable, piping, pipe, etc.

[0028] Here, the channel base C is a long body having a generally U-shaped cross section with opposing lip portions C3 formed on both end edges. That is, channel side portions C2 extend substantially perpendicularly from both end edges of a band-shaped channel bottom portion C1, and further, opposing short-side lip portions C3 extend substantially parallel to the channel bottom portion C1 from the end edges of both channel side portions C2 opposite the channel bottom portion C1. The conduit L placed on the opening side of such a channel base C, i.e., on the lip portion C3 side, is supported by the piping support bracket 1.

[0029] The pipe support fitting 1 includes a first support plate 2 and a second support plate 3 that are asymmetrical and have different shapes, and a connecting bolt 4 that connects these together.

[0030] The first support plate 2 is a member having first lip insertion portions 21a formed on both side edges of one end of a substantially rectangular plate material, and having the other end bent into an arc shape and a first flange portion 23 formed at the tip and protruding outward. Specifically, as shown in Fig. 3, from one end side, the first support plate 2 comprises, in order, a substantially flat first flat portion 21, an arc portion 22 connected to the first flat portion 21 and bent into a substantially arc shape, and a substantially flat first flange portion 23 connected to the arc portion 22 and protruding outward. The thickness and width of the first support plate 2 are set so as to obtain a predetermined strength required to firmly support and hold the conduit L.

[0031] A tip edge 21b on one end side (opposite the arc portion 22 side) of the first flat plate portion 21 extends substantially perpendicular to the longitudinal direction of the first flat plate portion 21, and corners on both sides extend obliquely toward the arc portion 22 side, making it easy to insert the lip portion C3 of the channel base C. In addition, first lip insertion portions 21a for inserting the lip portion C3 are formed on both side edges on one end side of the first flat plate portion 21, and the area between the first lip insertion portions 21a and the tip edge 21b forms a locking portion 21c that locks with the lip portion C3.

[0032] The first lip insertion portion 21a is a generally U-shaped notch that bites into the widthwise center of the first flat plate portion 21, and the opening side (bottom side of the U-shape) on the tip edge 21b side extends gently obliquely toward the arc portion 22 side and outward, thereby enabling the locking portion 21c to firmly lock onto the lip portion C3. On the other hand, the opening side (top side of the U-shape) on the arc portion 22 side extends obliquely toward the arc portion 22 side at a large angle (45° in this embodiment), thereby making it easier to insert the lip portion C3.

[0033] In this embodiment, both side edges of the first support plate 2, excluding the locking portion 21c, are bent outward to form bent portions 2a, so that when supporting piping such as cables, the piping is not damaged. In addition, a reinforcing portion 21d that protrudes outward is formed in the center between the first lip insertion portions 21a to increase strength.

[0034] The arc portion 22 is formed so that its inner surface is in contact with the outer peripheral surface of the conduit L, and the arc length is set so that the surface of the first flange portion 23 is positioned at an angle with respect to a reference plane S. That is, the reference plane S is a plane that is approximately perpendicular to the longitudinal direction of the channel base C and extends approximately above the opening (lip portion C3). Then, as will be described later, the arc length of the arc portion 22 is set so that, in this embodiment, the surface of the first flange portion 23 is positioned at an angle of approximately 60° with respect to the reference plane S (first flat plate portion 21) when the lip portion C3 is inserted into the first lip insertion portion 21a and the first flat plate portion 21 extends approximately perpendicular to the channel base C, thereby forming the first flange portion 23.

[0035] The reason why the surface of the first flange portion 23 is set at approximately 60° is because the inventors of the present application confirmed that setting it at approximately 60° makes it easiest to insert the lip portion C3 into the second lip insertion portion 31a, which will be described later. The same applies to the second flange portion 32, which will be described later.

[0036] A bolt insertion hole 23a for inserting the connecting bolt 4 is formed in the center of the first flange portion 23. The bolt insertion hole 23a is formed cylindrically by burring, and its inner diameter is set larger than the standard hole diameter specified by the Japanese Industrial Standards for the nominal diameter of the connecting bolt 4. For example, if the nominal diameter of the connecting bolt 4 is 6 mm, the Japanese Industrial Standards specify bolt hole diameters as 6.4 mm for Class 1, 6.6 mm for Class 2, and 7 mm for Class 3, but the inner diameter of the bolt insertion hole 23a is set to 8 mm. By making the bolt insertion hole 23a larger than the standard bolt hole diameter, the movable range of the connecting bolt 4, i.e., the second support plate 3, is increased, making it easier to insert the lip portion C3 into the second lip insertion portion 31a, which will be described later.

[0037] The second support plate 3 is a member in which second lip insertion portions 31a are formed on both side edges of one end of a substantially rectangular plate material, and a second flange portion 32 that protrudes outward is formed at the tip of the other end. Specifically, as shown in Fig. 4, a substantially rectangular plate material is bent to include, in order from one end, a substantially flat second flat portion 31 and a substantially flat second flange portion 32 that is connected to the second flat portion 31. The thickness and width of the second support plate 3 are set so that a predetermined strength required to firmly support and hold the conduit L is obtained even when a later-described avoidance portion 3b is formed.

[0038] The leading edge 31b on one end side (opposite the second flange portion 32 side) of the second flat plate portion 31 has the same shape as the leading edge 21b of the first flat plate portion 21. In addition, notched second lip insertion portions 31a for inserting the lip portion C3 of the channel base C are formed on both side edges on the one end side of the second flat plate portion 31, and the region between the second lip insertion portions 31a and the leading edge 31b forms a locking portion 31c that locks with the lip portion C3. The second lip insertion portions 31a have the same shape as the first lip insertion portion 21a.

[0039] In this embodiment, both side edges of the second support plate 3, excluding the locking portion 31c, are bent outward to form bent portions 3a, similar to the first support plate 2. In addition, a reinforcing portion 31d that protrudes outward to increase strength is formed in the center between the second lip insertion portions 31a.

[0040] The second flange portion 32 is formed so that its surface is positioned at an angle with respect to the reference plane S. That is, as will be described later, the second flange portion 32 is formed so that, in this embodiment, the surface of the second flange portion 32 is positioned at an angle of approximately 60° with respect to the reference plane S (second flat plate portion 31) when the lip portion C3 is inserted into the second lip insertion portion 31a and the second flat plate portion 31 extends approximately perpendicular to the channel base C.

[0041] A screw hole (female threaded portion) 32a into which the connecting bolt 4 is screwed is formed in the center of the second flange portion 32. This screw hole 32a is formed into a cylindrical shape by burring, and a female thread is formed on the inner peripheral surface thereof. In this embodiment, the screw hole 32a is formed as the female threaded portion, but a bolt insertion hole may be formed in the second flange portion 32 and a nut may be provided as the female threaded portion.

[0042] Furthermore, an avoidance portion 3b is provided from the second lip insertion portion 31a on one side edge portion of the second support plate 3 toward the second flange portion 32. This avoidance portion 3b is a shaped portion for preventing the second support plate 3 from interfering with the conduit L and the channel base C so that the lip portion C3 can be inserted into the second lip insertion portion 31a of the second support plate 3 when the first support plate 2 and the second support plate 3 are connected by the connecting bolt 4 and the lip portion C3 of the channel base C is inserted into the first lip insertion portion 21a of the first support plate 2.

[0043] In this embodiment, the avoidance portion 3b is formed in the shape of a notch spanning the second flange portion 32 from the second lip insertion portion 31a to the second flange portion 32. That is, the avoidance portion 3b is formed so as to cut out the second flange portion 32 side of the second lip insertion portion 31a, thereby cutting out a portion of the second flange portion 32 (leaving the free end side). The avoidance portion 3b is also formed so as not to cut into the second support plate 3 on the widthwise center side thereof relative to the second lip insertion portion 31a. As will be described later, the lip portion C3 can be inserted into the second lip insertion portion 31a by pushing the avoidance portion 3b into or against the conduit L. In other words, the avoidance portion 3b is formed to enable such insertion.

[0044] The connecting bolt 4 is a bolt that connects the first support plate 2 and the second support plate 3 by being inserted into the bolt insertion hole 23a and screwed into the threaded hole 32a, and its length is set longer than standard. For example, assuming that it is normal for the threads of a bolt to protrude approximately three to five times from a nut or the like after tightening, the connecting bolt 4 is set so that when tightened into the threaded hole 32a as described below, more than twice the standard number of threads protrudes from the threaded hole 32a. In this way, making the length of the connecting bolt 4 longer than standard increases the range of movement of the second support plate 3, making it easier to insert the lip portion C3 into the second lip insertion portion 31a. In other words, the length of the connecting bolt 4 is set longer than standard so that the lip portion C3 can be easily inserted into the second lip insertion portion 31a.

[0045] Next, we will explain how to support and hold the electric conduit L with the pipe support bracket 1 configured as described above. First, a first support plate 2 and a second support plate 3 are connected with a connecting bolt 4, and the second support plate 3 is disposed on the free end side of the connecting bolt 4.

[0046] First, as shown in Fig. 5, with the conduit L placed on the lip portion C3 side of the channel base C so as to be approximately perpendicular to the channel base C, both lip portions C3 are inserted into the first lip insertion portion 21a of the first support plate 2, and the arc portion 22 is aligned with the outer peripheral surface of the conduit L. Next, as shown in Fig. 6, the second support plate 3 is held and moved so that the lip portion C3 is inserted into the second lip insertion portion 31a of the second support plate 3.

[0047] At this time, as shown in Fig. 7, the avoiding portion 3b is pushed (pressed) into the electric conduit L, and the locking portion 31c on the avoiding portion 3b side is turned under the lip portion C3 and locked onto the lip portion C3. Next, the other locking portion 31c is also turned under the lip portion C3 and locked onto the lip portion C3, whereby the piping support fitting 1 is temporarily fixed to the channel base C so that the electric conduit L is sandwiched between the first support plate 2 and the second support plate 3, as shown in Fig. 8.

[0048] 9, the connecting bolts 4 are tightened to fix the piping support bracket 1 and the electric conduit L to the channel base C. In this arrangement, the first flat plate portion 21 and the second flat plate portion 31 extend substantially perpendicular to the channel base C, and the surfaces of the first flange portion 23 and the second flange portion 32 are positioned at approximately 60° with respect to the reference plane S.

[0049] As described above, according to this piping support fitting 1, the avoiding portion 3b that avoids interference with the electric conduit L and the channel base C is provided on the side edge portion of the second support plate 3, and therefore, it is possible to arrange the piping support fitting 1 on the channel base C even when the two support plates 2, 3 remain connected with the connecting bolt 4. That is, with the two support plates 2, 3 connected with the connecting bolt 4 and the lip portion C3 inserted into the first lip insertion portion 21a of the first support plate 2, the lip portion C3 can be inserted into the second lip insertion portion 31a of the second support plate 3 while avoiding interference with the electric conduit L and the channel base C with the avoiding portion 3b, thereby making it possible to arrange the piping support fitting 1 on the channel base C even when the two support plates 2, 3 remain connected.

[0050] In particular, in this embodiment, the avoidance portion 3b is formed in the shape of a notch that straddles the second flange portion 32. In other words, since the avoidance portion 3b is formed on the opposite side of the second lip insertion portion 31a, it is possible to insert the lip portion C3 into the second lip insertion portion 31a by pushing the avoidance portion 3b toward the conduit L to avoid interference with the channel base C, etc.

[0051] This eliminates the need to remove the connecting bolts 4 and separate the two support plates 2, 3 as in the past, reducing the effort and time required to install the piping support fitting 1. In particular, when installing a large number of piping support fittings 1, not only can the effort and time be significantly reduced, but the burden on the worker can also be significantly reduced. In addition, because there is no need to separate the two support plates 2, 3, there is no risk of losing the support plates 2, 3 or the connecting bolts 4.

[0052] Furthermore, the first flange portion 23 and the second flange portion 32 are formed so that their surfaces are positioned at approximately 60° with respect to a reference plane S that is approximately perpendicular to the longitudinal direction of the channel base C and extends approximately above the opening. In other words, the connecting bolt 4 is disposed so as to extend obliquely with respect to the channel base C, and the second support plate 3 is positioned on the channel base C side (the lower side of the electric conduit L), making it easy to insert the lip portion C3 into the second lip insertion portion 31a. As a result, the piping support fitting 1 can be disposed in the channel base C easily and quickly.

[0053] Furthermore, because the connecting bolts 4 extend diagonally relative to the channel base C, as shown in FIG. 10 , even when multiple electrical conduits L are closely spaced on the channel base C (when the distance between adjacent pipe support fittings 1 is short), the connecting bolts 4 can be tightened using an electric screwdriver D or the like. In other words, when the connecting bolts 4 extend parallel to the channel base C as in the past, the adjacent pipe support fittings 1 get in the way, making it difficult to tighten the connecting bolts 4 with an electric screwdriver. In contrast, because the connecting bolts 4 extend diagonally, the adjacent pipe support fittings 1 do not get in the way, making it possible to properly tighten the connecting bolts 4. In other words, it is possible to arrange multiple electrical conduits L with a narrower spacing between adjacent fittings.

[0054] Furthermore, since the second support plate 3 is composed only of a second flat plate portion 31 having an approximately flat plate shape and a second flange portion 32, the configuration is simple and it is possible to reduce manufacturing costs, including mold costs.

[0055] The shapes of the support plates 2, 3, etc. are not limited to those described above, and may be any appropriate shape depending on the size of the conduit L and the shape of the channel base C. For example, as shown in Fig. 11, the second flat plate portion 31 of the second support plate 3 may be made relatively long, and an avoidance portion 3b may be provided on the second flange portion 32 side so as not to overlap the second lip insertion portion 31a.

[0056] (Embodiment 2) 12(a) is a front view showing a first example of the shape of the second support plate 3 of the pipe support fitting according to this embodiment. This embodiment differs from the first embodiment in that the leading edge 31b of the second support plate 3 on the second lip insertion portion 31a side is formed in a generally arcuate shape that protrudes outward, and the same components as those in the first embodiment are denoted by the same reference numerals and will not be described again.

[0057] That is, the tip edge 31b is formed in the shape of a single arc that protrudes outward over its entire length and is approximately symmetrical, and the radius of curvature R of the arc is set so that the lip portion C3 can be inserted into the second lip insertion portion 31a without interfering with the second support plate 3 and the electric conduit L and the channel base C, or so that the insertion is easy.

[0058] In this way, because the tip edge 31b is formed in an arc shape, the second support plate 3 does not interfere with the electric conduit L or the channel base C, and the lip portion C3 can be easily inserted into the second lip insertion portion 31a. As a result, the piping support fitting can be easily and quickly arranged in the channel base C.

[0059] Incidentally, as in the second shape example shown in Figure 12(b), the second support plate 3 does not necessarily have to have the bent portions 3a formed on both side edges, and this is also the case in the above-mentioned embodiment 1 and the embodiments 3 and 4 described below.

[0060] (Embodiment 3) 13(a) is a front view showing the second support plate 3 of the pipe support fitting according to this embodiment. In this embodiment, the position and shape of the avoidance portion 3b differ from those in embodiment 1, and the same components as those in embodiment 1 are given the same reference numerals and their description will be omitted.

[0061] The avoidance portion 3b in this embodiment overlaps the second flange portion 32 side of the second lip insertion portion 31a and is formed as a notch that bites into the second support plate 3 closer to the center than the second lip insertion portion 31a. That is, in the case of a second support plate in which the avoidance portion 3b is not formed as shown in Fig. 13(b), the second flange portion 32 side of the second lip insertion portion 31a (the anti-locking portion 31c side) is cut out and the avoidance portion 3b is formed so as to bite into the width center side of the second flat plate portion 31 closer to the reinforcing portion 31d than the second lip insertion portion 31a.

[0062] As a result, the lip portion C3 can be inserted into the second lip insertion portion 31a by pushing it up to one of the avoidance portions 3b and inserting both locking portions 31c under the lip portion C3 to lock it in place. In other words, the position and shape of the avoidance portion 3b are set to allow this type of insertion. In this way, by inserting the lip portion C3 up to the avoidance portion 3b and avoiding interference with the channel base C, etc., the lip portion C3 can be inserted into the second lip insertion portion 31a. Furthermore, because the locking portion 31c side of the second lip insertion portion 31a remains, the second support plate 3 can be disposed on the channel base C without any play, with the locking portions 31c locked in place on the lip portion C3.

[0063] In this embodiment, since the avoidance portions 3b are provided on both side edges of the second support plate 3, the lip portion C3 can be inserted into the second lip insertion portion 31a from either side. However, as described above, it is necessary to set the thickness and width of the second support plate 3 (and the strength of the material, if necessary) so that a predetermined strength is obtained. In this way, the avoidance portions 3b may be provided on both side edges of the second support plate 3, as in the above-mentioned embodiments 1 and 2, and the embodiment 4 described below.

[0064] (Fourth embodiment) 14A is a front view showing the second support plate 3 of the pipe support fitting according to this embodiment, and FIG. 14B is a YY cross-sectional view of FIG. 14A. In this embodiment, the shape of the avoidance portion 3b is different from that of the first embodiment, and the same components as those of the first embodiment are designated by the same reference numerals and will not be described.

[0065] The avoidance portion 3b in this embodiment is formed by bending a part of the side edge of the second support plate 3 toward the side opposite to the first support plate 2. That is, the second flange portion 32 side of the second lip insertion portion 31a and a bent portion 31e that is part of the second flange portion 32 are bent toward the side opposite to the first support plate 2 (the side opposite to the conduit L), and the avoidance portion 3b that spans from the second lip insertion portion 31a to the second flange portion 32 is formed.

[0066] In this way, since the avoidance portion 3b is not a notch but is formed by bending a part of the side edge portion of the second support plate 3, it is possible to increase the strength and rigidity of the second support plate 3.

[0067] Although the embodiments of the present invention have been described above, the specific configuration is not limited to the above embodiments, and the present invention also includes design changes within the scope of the present invention. For example, in the above embodiments, the surfaces of the first flange portion 23 and the second flange portion 32 are positioned at approximately 60° with respect to the reference plane S, but they may be positioned at any angle depending on the size of the piping and the shape of the support plates 2, 3, etc. The inventors have confirmed that when the outer diameter of the piping is large, an angle in the range of 45° to 90° is desirable.

[0068] Furthermore, the shape of the locking portions 21c, 31c is not limited to the above shapes, and may be, for example, arc-shaped or chamfered, and may also be shorter in length. Also, in the second embodiment, the entire tip edge 31b of the second support plate 3 is formed in an arc shape, but other shapes are also possible, for example, it may be formed into a substantially arc shape by chamfering. Furthermore, a reversing portion 3a may be provided in the avoidance portion 3b.
