Description

[Technical Field]

[0001] The present invention relates to a support for an elongated body. [Background technology]

[0002] Long body supports are used to support long bodies such as refrigerant pipes in buildings and other structures. For example, an angle bar may be fixed to the building, the long body may be positioned crosswise relative to the angle bar, and the long body may be supported relative to the angle bar by the long body support. An example of such a long body support is disclosed in JP 2022-156338 A (Patent Document 1).

[0003] The long body support (piping support device 1) of Patent Document 1 includes a U-bolt 11 that is passed through an angle material (L-shaped angle LA) and surrounds the long body (piping PL) between the angle material and the U-bolt 11, and nuts 12 that are screwed onto the threaded portions at both ends of the U-bolt 11. By tightening the two nuts 12, the U-bolt 11 is fixed to the angle material while surrounding the long body, and the long body is thereby supported by the angle material.

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-156338 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the long body support device of Patent Document 1, the tightening operation of the two nuts 12 must be performed on the back side of the angle bar, which not only requires a small working space but also makes it difficult to see, resulting in poor workability.

[0006] It is desirable to realize a support tool for long objects that is easy to work with. [Means for solving the problem]

[0007] The elongated body support device according to the present invention comprises: A long body support device for supporting a long body arranged across an angle member, a holding portion for holding the elongated body in a holding space formed between the holding portion and the angle bar; clamping means connected to the holding portion and configured to detachably clamp a first portion of the angle member; Equipped with.

[0008] With this configuration, while the elongated body is held in the holding space of the holding part, the first portion of the angle bar is clamped by the clamping means, thereby fixing the holding part to the angle bar and supporting the elongated body relative to the angle bar. Clamping of the first portion of the angle bar by the clamping means can be easily performed in a visible state from the front side or outside of the first portion of the angle bar, where there is relatively ample space. Therefore, a elongated body support device with excellent workability can be provided.

[0009] Preferred embodiments of the present invention will be described below, but the scope of the present invention is not limited to the preferred embodiments described below.

[0010] In one embodiment, It is preferable that the clamping means has an abutment portion that is arranged in abutment along the first portion of the angle iron, and a fixing portion that is arranged on the opposite side of the abutment portion from the first portion of the angle iron, and that the first portion of the angle iron is removably clamped between the abutment portion and the fixing portion.

[0011] According to this configuration, a structure can be easily realized in which the abutment portion and the fixing portion, which are arranged on opposite sides of the first portion of the angle iron, detachably sandwich the first portion of the angle iron between them.

[0012] In one embodiment, the clamping means further includes a fastening bolt inserted through the abutment portion and an internal thread portion into which the fastening bolt is screwed, It is preferable that the internal thread portion is integrally formed with the fixing portion.

[0013] With this configuration, the fastening bolt is fastened to move the abutting portion and the fixed portion closer to each other, so that the first portion of the angle iron can be easily and firmly sandwiched between the abutting portion and the fixed portion. The fastening bolt can be fastened from the front side of the first portion of the angle iron, where there is often ample space, further improving workability.

[0014] In one embodiment, It is preferable that a position maintaining mechanism be provided that maintains the fixing portion in a position overlapping the first portion of the angle member when the fastening bolt is fastened.

[0015] With this configuration, when tightening the fastening bolt, the fixing portion and the first portion of the angle iron are kept overlapping without the worker being particularly conscious of it. Therefore, by simply continuing to tighten the fastening bolt, the first portion of the angle iron can be sandwiched between the abutment portion and the fixing portion, further improving workability.

[0016] In one embodiment, It is preferable that the angle member further comprises a locking arm that extends from the holding portion along the second portion of the angle member and locks onto an end of the second portion.

[0017] With this configuration, the holding part can be temporarily held on the angle bar while the locking arm is locked onto the end of the second part of the angle bar. Therefore, the clamping operation of the first part of the angle bar with the clamping means can be performed without holding down the holding part, while keeping both hands free. This further improves workability.

[0018] In one embodiment, The holding portion is formed in a U-shape having a pair of legs and a connecting portion that connects the pair of legs together, It is preferable that the clamping means is provided on only one of the pair of legs that constitute the holding portion.

[0019] With this configuration, by installing the clamping means on only one of the pair of legs, it is possible to ensure a minimum level of fixing force to the angle bar while reducing the number of clamping operations, thereby further improving workability.

[0020] In one embodiment, The angle iron is preferably a holeless angle iron.

[0021] The elongated body support device of the present invention is fixed to the angle iron by clamping the first part of the angle iron between the abutment portion and the clamping means, so that even if the angle iron to be attached is a holeless angle iron without an insertion hole, the elongated body support device can be fixed to the holeless angle iron without any problems.

[0022] Further features and advantages of the present invention will become more apparent from the following description of exemplary and non-limiting embodiments, which is given with reference to the drawings. [Brief explanation of the drawings]

[0024] An embodiment of a support for a long body will be described with reference to the drawings. As shown in Fig. 1, a support for a long body 1 is used to support a long body 9 that is arranged to cross an angle iron 8. In this embodiment, the support for a long body 1 fixes the angle iron 8 horizontally to a structure such as a building, and supports the long body 9 that is arranged vertically perpendicular to the angle iron 8.

[0025] The angle iron 8 is fixed to the building in the horizontal direction. The angle iron 8 is a steel material with an L-shaped cross section, and angle irons such as equal-leg angle irons and unequal-leg angle irons can be used. The angle iron 8 may be, for example, a perforated angle iron with an insertion hole formed therein through which the shank of a bolt can be inserted, or a holeless angle iron without such an insertion hole. FIG. 1 shows an example in which a holeless equal-leg angle iron is used as the angle iron 8.

[0026] The angle iron 8 has a first portion 81 and a second portion 82 that is perpendicular to the first portion 81. In this embodiment, the first portion 81 and the second portion 82 are the same size. In this embodiment, the first portion 81 is fixed to the building and arranged in the vertical direction. The second portion 82 is fixed to the building and arranged in the horizontal direction.

[0027] The elongated body 9 is an elongated object, and in this embodiment, is arranged in the vertical direction. The elongated body 9 in this embodiment includes, for example, a piping member 91 through which a refrigerant of an air conditioner flows, and a heat insulating material 92 surrounding the piping member 91.

[0028] The elongated body support device 1 is fixed to the angle bar 8 in a state in which it surrounds one or more elongated bodies 9 from the outside, thereby supporting the elongated bodies 9 relative to the angle bar 8.

[0029] As shown in FIG. 2, the elongate body support device 1 has a holding portion 10 and a clamping means 20 as its main components. The elongate body support device 1 also has a locking arm 40. In this embodiment, the holding portion 10, a portion of the clamping means 20 (abutment portion 21 described below), and the locking arm 40 are integrally formed. The other portion of the clamping means 20 (fixing portion 31 and fastening bolt 35 described below) are configured as separate bodies from the integrated holding portion 10, abutment portion 21, and locking arm 40.

[0030] The holding part 10 holds the elongated body 9 in a holding space R (see FIG. 1 ) formed between the holding part 10 and the angle iron 8. The holding part 10 is formed using a strip-like member having a predetermined width in the vertical direction (in this example, a length slightly shorter than the first portion 81 of the angle iron 8) and is U-shaped when viewed in the vertical direction. The holding part 10 has a pair of opposing legs 11 and a connecting part 12 connecting the pair of legs 11 to each other. The legs 11 are arranged in an orientation perpendicular to the first portion 81 of the angle iron 8. The connecting part 12 is arranged in an orientation parallel to the first portion 81 of the angle iron 8 with a predetermined distance between them. The holding space R is formed as a space surrounded by the pair of legs 11, the connecting part 12, and the first portion 81 of the angle iron 8, and the holding part 10 holds the elongated body 9 in the holding space R.

[0031] In this example, the boundary between the leg portion 11 and the connecting portion 12 is formed in a rounded shape that follows the outer surface of the elongated body 9 (specifically, the heat insulating material 92). However, without being limited to this configuration, the boundary between the leg portion 11 and the connecting portion 12 may be formed in a C-shaped shape, or may be formed to have a corner.

[0032] In this embodiment, the holding portion 10 further has an extension portion 13 extending downward from the leg portion 11. The extension portion 13 is provided on only one of the pair of legs 11 and is formed integrally with that leg portion 11. The extension portion 13 extends further downward beyond the lower end of the first portion 81 of the angle iron 8 (see FIG. 1). The extension portion 13, together with the leg portion 11, is disposed in an orientation perpendicular to the first portion 81 of the angle iron 8.

[0033] The clamping means 20 is connected to the holding portion 10 and detachably clamps the first portion 81 of the angle iron 8. As shown in FIG. 2 , the clamping means 20 of this embodiment has a contact portion 21, a fixing portion 31, a fastening bolt 35, and an internal thread portion 38.

[0034] In this embodiment, the abutment portion 21 is integrated with the holding portion 10. Since the abutment portion 21 is integrated with the holding portion 10, the clamping means 20 is connected to the holding portion 10. The abutment portion 21 is arranged to abut along the first portion 81 of the angle iron 8. In this embodiment, the abutment portion 21 is integrated with one leg portion 11 of the holding portion 10 and the extension portion 13 connected thereto. The abutment portion 21 is formed in a flat plate shape. The abutment portion 21 is perpendicular to the one leg portion 11 and the extension portion 13 and is arranged to abut along the entire surface of the first portion 81 of the angle iron 8. The abutment portion 21, together with the extension portion 13, extends further downward beyond the lower end of the first portion 81 of the angle iron 8 (see FIG. 1 ). An insertion hole 22 is formed through a portion of the abutment portion 21 that is located further below the first portion 81 of the angle iron 8. A shaft portion 35B of a fastening bolt 35 is inserted into this insertion hole 22.

[0035] A bent piece 25 extends from the abutting portion 21. The bent piece 25 is formed so as to bend and extend from the lower end side of the abutting portion 21 toward the rear side. The bent piece 25 extends in the front-to-rear direction beyond the first portion 81 of the angle iron 8 and further to the rear side (see FIG. 4). The side wall portion 31B of the fixing portion 31 can abut against this bent piece 25 (see FIG. 5).

[0036] The fixing portion 31 is disposed on the opposite side of the abutment portion 21 with respect to the first portion 81 of the angle iron 8. The abutment portion 21 abuts against the first portion 81 of the angle iron 8 from the front side, and the fixing portion 31 is disposed on the rear side of the first portion 81 of the angle iron 8. The fixing portion 31 has a main body 31A and a pair of side wall portions 31B erected from both ends of the main body 31A. The main body 31A is formed in a flat plate shape and is disposed parallel to the abutment portion 21. The side wall portions 31B erect from the main body 31A toward the abutment portion 21 side (front side). The tip of the side wall portion 31B can abut against the first portion 81 of the angle iron 8 from the rear side (see Figure 6).

[0037] In this embodiment, the tip of the side wall portion 31B is formed in a sawtooth shape, which reduces the contact area between the fixing portion 31 and the first portion 81 when the clamping means 20 clamps the first portion 81 of the angle iron 8, increasing the surface pressure and enabling the elongated body support tool 1 to be firmly fixed to the angle iron 8.

[0038] The fastening bolt 35 connects the abutment portion 21 and the fixed portion 31. The fastening bolt 35 has a head portion 35A and a shaft portion 35B. The head portion 35A is the operated portion that is operated with a tool when fastening the fastening bolt 35. The shaft portion 35B is inserted into the abutment portion 21 (the insertion hole 22 formed therein). The shaft portion 35B is externally threaded. The external threads of the shaft portion 35B are threaded into the internal thread portion 38. The internal thread portion 38 into which the fastening bolt 35 is threaded is provided integrally with the fixed portion 31. In this embodiment, the internal thread portion 38 is formed directly in the main body portion 31A of the fixed portion 31 by tapping.

[0039] By tightening the fastening bolt 35, the fixing portion 31 moves closer to the head portion 35A and the abutment portion 21, sandwiching the first portion 81 of the angle iron 8 between the abutment portion 21 and the fixing portion 31 (see Figure 6).

[0040] In this embodiment, the elongate body support tool 1 has only one clamping means 20. The clamping means 20 is provided on only one of the pair of legs 11 that make up the holding part 10 (the one that is integrated with the extension part 13).

[0041] The locking arm 40 extends from the holding part 10 along the second portion 82 of the angle iron 8 and locks onto the end of the second portion 82. In this embodiment, the locking arm 40 extends from each of the pair of legs 11 that make up the holding part 10 along the second portion 82 of the angle iron 8. The locking arm 40 is integrally connected to the upper end of the leg 11. The locking arm 40 has an extension part 41 that extends linearly from the leg 11 and a locking part 42 formed in a curved shape at the tip of the extension part 41. The extension length of the extension part 41 from the holding part 10 corresponds to the width of the second portion 82 of the angle iron 8, and the locking part 42 provided at the tip of the extension part 41 locks onto the end of the second portion 82 of the angle iron 8 (see Figures 1 and 6, etc.).

[0042] To support a long body 9 on an angle member 8 using the long body support device 1 of this embodiment, first, as shown in Figure 3, the long body 9 is positioned in a vertical direction adjacent to the first portion 81 of the angle member 8. In this state, the long body support device 1 is attached to the angle member 8 so as to surround the long body 9 from the outside at the point where the angle member 8 and the long body 9 intersect.

[0043] At this time, in the clamping means 20, the fixing portion 31 is rotated downward when the fastening bolt 35 is in a loosened state, and most of the fixing portion 31 does not overlap with the first portion 81 when viewed from the front of the angle iron 8 (see Figures 4 and 5). Therefore, the long body support device 1 can be properly attached to the angle iron 8 without interfering with the first portion 81 of the angle iron 8.

[0044] 4, in this embodiment, the locking arm 40 locks onto the end of the second portion 82 on the opposite side of the first portion 81, which is the portion of the angle iron 8 that is clamped by the clamping means 20. This allows the long body support 1 to be temporarily held onto the angle iron 8. Therefore, the subsequent tightening operation of the fastening bolt 35 can be performed with both hands free without having to hold down the long body support 1, improving workability.

[0045] The fastening bolts 35 can be fastened from the front side of the angle iron 8. There is often ample space on the front side of the angle iron 8, and in such cases the fastening bolts 35 can be fastened using, for example, an electric tool, which significantly improves workability.

[0046] When the fastening bolt 35 is tightened, the fixing portion 31, which is threadedly attached to it by the internal thread portion 38, also rotates. This rotation of the fixing portion 31 continues until the edge of one side wall portion 31B abuts against the upper surface of the bent piece 25, as shown in FIG. 5. In this state, the fixing portion 31 is in a position where most of the pair of side wall portions 31B overlaps with the first portion 81 when viewed from the front of the angle iron 8 (hereinafter, this may be referred to as the "overlapping position"). After one side wall portion 31B and the bent piece 25 abut against each other, the overlapping position of the fixing portion 31 is maintained even if the fastening bolt 35 is tightened.

[0047] In this embodiment, the side wall portion 31B and the bent piece 25 that abut against each other form a position maintaining mechanism P that maintains the fixing portion 31 in the overlapping position as the fastening bolt 35 is fastened.

[0048] When the fastening bolt 35 is further tightened, as shown in Fig. 6, the abutment portion 21 and the first portion 81 of the angle iron 8 are sandwiched between the head 35A of the fastening bolt 35 and the fixing portion 31, thereby fixing the elongated body support tool 1 to the angle iron 8. In this way, the elongated body 9 can be supported by the angle iron 8 with good workability.

[0049] Other Embodiments (1) In the above embodiment, an example has been described in which the clamping means 20 is configured as a bolt-fastening type using the fastening bolt 35. However, the present invention is not limited to such a configuration, and the clamping means 20 may be configured as, for example, a clip-type. Such a clip-type clamping means 20 may have, for example, the same abutting portion 21 and fixing portion 31 as in the above embodiment, and an elastic member (typically, a spring plate member) that biases the abutting portion 21 and fixing portion 31 toward each other. The clip-type clamping means 20 can be attached from the outside (bottom side) of the first portion 81 of the angle iron 8, where there is often relatively more space.

[0050] (2) In the above embodiment, the internal thread portion 38 onto which the fastening bolt 35 is threaded is integrally formed on the fixed portion 31 by tapping, and the internal thread portion 38 is directly formed on the main body 31A of the fixed portion 31. However, the present invention is not limited to such a configuration, and for example, a fastening nut having the internal thread portion 38 may be integrally fixed to the fixed portion 31.

[0051] (3) In the above embodiment, an example has been described in which the internal thread portion 38 onto which the fastening bolt 35 is threaded is provided integrally with the fixing portion 31. However, the present invention is not limited to such a configuration. For example, a fastening nut having the internal thread portion 38 and separate from the fixing portion 31 may be threaded onto the shank 35B of the fastening bolt 35 on the back surface side of the fixing portion 31.

[0052] (4) In the above embodiment, the clamping means 20 is provided on only one of the pair of legs 11 that make up the holding part 10. However, the present invention is not limited to such a configuration, and for example, two clamping means 20 may be provided separately on both sides of the holding part 10.

[0053] (5) In the above embodiment, an example has been described in which the elongate body support tool 1 further includes a locking arm 40 in addition to the holding portion 10 and the clamping means 20. However, the present invention is not limited to such a configuration, and the locking arm 40 does not necessarily have to be provided.

[0054] (6) In the above embodiment, an example has been described in which the position maintaining mechanism P is configured by one of the side wall portions 31B and the bent piece 25 abutting against each other, maintaining the fixed portion 31 in the overlapping position in conjunction with the fastening operation of the fastening bolt 35. However, without being limited to such a configuration, the specific configuration of the position maintaining mechanism P may be arbitrary, for example, by providing a convex portion and a concave portion that engage with each other separately on the abutting portion 21 and the fixed portion 31. Furthermore, the position maintaining mechanism P does not necessarily have to be provided.

[0055] (7) In the above embodiment, the abutting portion 21 extends from the holding portion 10. However, the present invention is not limited to such a configuration, and the abutting portion 21 may extend from the locking arm 40, for example.

[0056] (8) In the above embodiment, an example has been described in which the abutting portion 21 constituting the clamping means 20 is integrated with the holding portion 10. However, the present invention is not limited to such a configuration. For example, as shown in FIG. 7 , the abutting portion 21 may be configured separately from the holding portion 10. In this example, the clamping means 20 includes a connecting portion 26 integrated with the holding portion 10, a contact portion 21 separate from the holding portion 10, a fixing portion 31, a fastening bolt 35, and an internally threaded portion 38. An insertion hole 27 through which the shank 35B of the fastening bolt 35 is inserted is formed in the connecting portion 26. The fastening bolt 35 is inserted through the insertion hole 27 of the connecting portion 26 and the insertion hole 22 of the abutting portion 21 and is threaded into the internally threaded portion 38 of the fixing portion 31. Even in this configuration, when the fastening bolt 35 is tightened, the first portion 81 of the angle bar 8 is clamped between the abutting portion 21 and the fixing portion 31 via the connecting portion 26.

[0057] (9) In the above embodiment, an example has been described in which the fastening bolt 35 constituting the clamping means 20 plays an indirect role in clamping the first portion 81 of the angle iron 8 by moving the abutting portion 21 and the fixing portion 31 closer to each other. However, the present invention is not limited to such a configuration, and as shown in FIG. 8 , for example, the fastening bolt 35 may directly contribute to clamping the first portion 81 of the angle iron 8. In this example, the clamping means 20 includes a U-shaped plate 33 integrated with the holding portion 10 and the fastening bolt 35. The U-shaped plate 33 includes a front plate 33A having an internal thread portion 34 formed therein, a rear plate 33B disposed on the rear side of the first portion 81 of the angle iron 8, and a connecting plate 33C connecting the front plate 33A and the rear plate 33B below the first portion 81 of the angle iron 8. In this configuration, when the fastening bolt 35 is screwed into the internal thread portion 34 of the front plate portion 33A and tightened, the first portion 81 of the angle iron 8 is sandwiched between the tip of the fastening bolt 35 and the rear plate portion 33B.

[0058] (10) In the above embodiment, an example has been described in which the first portion 81 of the angle iron 8 is arranged in the vertical direction and the second portion 82 is arranged in the horizontal direction. However, the present invention is not limited to such a configuration, and the first portion 81 of the angle iron 8 may be arranged in the horizontal direction and the second portion 82 may be arranged in the vertical direction. In this case, the elongated body support 1 supports the elongated body 9 arranged in the horizontal direction on the upper surface side of the angle iron 8 in an orthogonal state.

[0059] (11) In the above embodiment, the elongated body 9 supported by the elongated body support 1 has a piping member 91 and a surrounding insulating material 92. However, the elongated body 9 is not limited to such a configuration, and may be, for example, composed of only the piping member 91, or may be a cable member such as an electric cable or a communication cable.

[0060] (12) The configurations disclosed in the above-described embodiments (including the above-described embodiments and other embodiments; the same applies hereinafter) can be applied in combination with configurations disclosed in other embodiments, as long as no contradiction occurs. Regarding other configurations, the embodiments disclosed in this specification are illustrative in all respects and can be appropriately modified within the scope of the present disclosure.
