Description

[Technical Field]

[0001] The present invention relates to a method of supporting an elongated body and a supporting bracket for suspending an object from an elongated body that is asymmetric in cross section, such as a channel or L-shaped angle, or for suspending and installing the elongated body itself. [Background technology]

[0002] Generally, to suspend and install supported parts such as pipes, electrical materials, or equipment from the framework of a building, such as the ceiling, a channel (also called a lip channel steel or C-channel) is fixed to the framework, and the supported object is suspended from the channel via a hanging bracket and installed on the framework. Turnbuckles (see Patent Document 1) or the like are used as the hanging bracket to install the channel on the hanging bolt, but channels come in a variety of shapes on the market, and processing such as drilling is performed on site as necessary.

[0003] The following technologies (1) to (4) are available for this type of hanging hardware. (1) A hanging hardware for channel materials has been proposed in which a bolt is passed through the opening of the channel and a middle nut is hooked from the inside onto the folded portion (lip portion) around the opening of the channel to secure it (see Patent Document 2).

[0004] However, the hanging hardware of Patent Document 2 requires the time and effort of drilling a hole to pass the bolt through the opening. In addition, the nut must be fastened in a narrow opening, which requires the nut to be held with the fingers during installation, which is time-consuming.

[0005] (2) A fixing fixture has been proposed that has a first retaining portion that holds a bolt fixed to the ceiling and a second retaining portion that holds a channel, and that has a first rotation guide portion that rotates the inner abutment portion so that the first direction is aligned with the extension direction of the channel as the fixing fixture moves closer to the channel (see Patent Document 3).

[0006] However, the fixing bracket of Patent Document 3 is attached by passing a rotation guide member through an upward opening, which means that the opening of the channel is limited to facing upward, and it cannot be installed sideways or downward.

[0007] (3) A connecting fitting has been proposed for cross-constructing channels, which includes a first retaining portion that holds the first channel and a second retaining portion that holds the second channel, and the second retaining portion has an outer abutment portion that abuts against a pair of lip portions of the second channel from the outside, and an inner abutment portion that abuts against the pair of lip portions of the second channel from the inside (see Patent Document 4).

[0008] However, with the connecting fittings of Patent Document 4, if it is desired to install the channel opening sideways or downwards, it is necessary to drill holes in the channel, which makes installation time-consuming and increases the workload and costs.

[0009] (4) For the connecting members that intersect the channels, a support device has been proposed that includes an orthogonal connecting member that connects the upper channel (frame member) and the lower channel (frame member) in a crisscross pattern while orthogonally intersecting each other, a hanging member connecting member that connects the hanging member hanging from the ceiling structure to the upper surface of the pair of upper channels, and a support member that is attached to the underside of the pair of lower channels and consists of support bolts, nuts, etc. that support the ceiling-suspended object in a suspended state (see Patent Document 5).

[0010] However, with the support device of Patent Document 5, if it is desired to install the opening in a desired orientation, such as sideways, upward, or downward, it is necessary to drill holes in the channel, which makes installation time-consuming and increases the workload and costs.

[0024] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0025] [Embodiment] 1 is an explanatory diagram of a channel support construction method according to an embodiment, in which support fittings are used to construct a lattice structure. Note that in this embodiment, a channel is described as an example of a long body that is asymmetric in cross section, but the present invention can also be applied to long bodies with other structures.

[0026] As shown in Figure 1, in the channel support method of the embodiment, when supporting a channel, a support bracket 12 is used to surround and support a channel 10 having an opening 10a on the side, multiple channels 10, 10 are made to intersect with each other, and support brackets 12 (polygonal bands 16) are installed at the intersections 14 of each channel 10, 10, and the multiple channels 10, 10 are constructed in a crisscross pattern using support brackets 12 connecting the installed polygonal bands 16, 16, and a support object (corresponding to the "object") 30 is suspended from the multiple channels 10, 10 constructed in a crisscross pattern using polygonal bands 16, and the multiple channels 10, 10 constructed in a crisscross pattern are themselves installed on structural steel 24 using polygonal bands 16.

[0027] The support fitting of the present invention is preferably a polygonal band having three or more points of contact with the elongated body, and the three or more points of contact within the polygonal band firmly support the elongated body by restricting its rotation. In other words, since the band that surrounds and supports the elongated body can be triangular in cross section, it is preferable that the band have three or more points of contact with the elongated body.

[0028] The support fitting 12 of this embodiment surrounds and supports the channel 10, and includes a polygonal band 16 whose position can be selectively set on at least two sides of the outer periphery of the channel 10. The polygonal band 16 has a polygonal shape when viewed in the axial direction, so that the opening direction of the elongated body can be freely selected, and the polygonal band 16 abuts on at least two surfaces of the elongated body in surface contact, so that it can be firmly supported in the selected direction.

[0029] The supporting method according to the embodiment shown in FIG. 1 employs the structure of the supporting fixtures according to the embodiments described below in order to construct a plurality of channels in a grid pattern.

[0030] As shown in Figures 2 to 4, the support bracket 12A of the first embodiment supports the channel 10 by connecting it to a hanging bracket 20 having a flange nut 26 that screws onto the hanging screw 18A using a through bolt 28 (bolt body 28a, nut 28b: corresponding to the "connecting member").

[0031] 5 and 6, support fitting 12B of the second embodiment uses hanging fitting 22 having notch 22a, and hanging screw 18B is attached to hanging fitting 22 which is fixed with a nut and connected by through bolt 28. Hanging screw 18B is used to hang various types of supported object 30 (see FIG. 1).

[0032] As shown in FIGS. 7 and 8, a support fitting 12C of the third embodiment is formed by connecting a plurality of polygonal bands 16, 16 to each other.

[0033] As shown in FIGS. 9 and 10, a support fitting 12D of the fourth embodiment is connected to a fixing fitting 32 (see FIG. 1) fixed to a structural steel 24.

[0034] [First embodiment] As shown in Figures 2 and 3, the support bracket 12A of the first embodiment is a support bracket 12A that supports a channel 10 having an opening 10a on its side, and is provided with a polygonal band 16 that surrounds and supports the channel 10, and at least two surfaces on the outer periphery of the channel 10 can be selectively positioned, and the polygonal band 16 has an insertion hole formed therein for inserting a through bolt 28 (corresponding to a "connecting member"), and is provided with a rotating part for opening and closing the polygonal band.

[0035] Furthermore, support bracket 12A is connected to hanger bracket 20 having flange nut 26 onto which hanger screw 18A is threaded, and hanger bracket 20 and polygonal band 16 are connected by through-bolt 28 (connecting member). Through-bolt 28 has nut 28b threadedly engaged with bolt body 28a, and nut 28b is tightened against bolt body 28a to secure support bracket 12 to hanger bracket 20.

[0036] The lifting hardware 20 has a turnbuckle structure in which a flange nut 26 is rotatably attached to a frame 20a. The flange nut 26 consists of a body 26a and a flange 26b. The frame 20a has an insertion hole 20a2 in a horizontal upper plate 20a1 into which the body 26a of the flange nut 26 is inserted, and a pair of downward-facing lower plates 20a3, 20a3 have bolt holes 20a4, 20a4 through which polygonal bands 16 or the like are passed and bolts 28 are passed to secure the frame. Protrusions 20a5, 20a5 (see Figure 4) are often provided to prevent the flange nuts 26 from falling off during transportation, etc.

[0037] The polygonal band 16 is formed in a polygonal shape having at least four sides on the outer periphery of the channel 10, when viewed in the axial direction along the length of the channel 10, so that two surfaces of the polygonal band 16 can be selectively positioned.

[0038] For example, if the polygonal band is octagonal, it can provide strong support whether the channel opening is facing upward or to the right. The channel has a roughly rectangular cross-section with both the longitudinal and lateral directions, and the supporting objects vary, including piping and equipment, so the opening direction can be selected as desired. Making the band rectangular to fit the longitudinal direction allows for good fit, but there is a risk of misalignment in the lateral direction. Therefore, making the band octagonal allows for fit in the longitudinal direction while restricting misalignment in the lateral direction with the edges, achieving strong support regardless of the opening direction. Furthermore, while the band shown in the embodiment is symmetrical, the polygonal band of the present invention does not have to be entirely polygonal; it can simply include a polygonal portion, and may have an asymmetrical shape, such as a semicircular side and a polygonal side.

[0039] 2 to 4, polygonal band 16 has a rotating portion in which one upper end portion is separated and the other lower end portion is rotatably connected by hinge 16a, and pieces 16b, 16b having insertion holes (not shown) formed therein, protrude from both sides of the separated end portion in the outer circumferential direction of polygonal band 16. With channel 10 housed within polygonal band 16, through-bolts 28 are inserted through the insertion holes formed in each of pieces 16b, 16b, and the pieces 16b, 16b are fastened together by through-bolts 28, thereby making it possible to fix channel 10 to polygonal band 16.

[0040] The rotating part is provided at the bottom of the polygonal band 16, and has a hinge mechanism (hinge 16a) that rotates around the rivet by fastening a rivet to a hole formed by curling the polygonal band 16, and the channel 10 can be inserted into the polygonal band 16 from the side, improving workability. The rotating part shown in the embodiment is a hinge mechanism, but it may also be an assembly-type mechanism in which a protrusion is provided on one side of the polygonal band and a groove is provided on the other, or a lantern-type mechanism in which the polygonal band is formed from a thin plate and opens and closes using elastic force.

[0041] The polygonal band 16 has an upper edge 16u separated by a gap, and a lower edge 16d separated by a hinge 16a between the two edges, allowing it to be freely folded. The right and left edges 16r and 16l are straight and face each other. A portion 16s connects the edges 16u, 16r, 16d, and 16l. In this embodiment, the edges 16u, 16r, 16d, and 16l and the connecting portions 16s form an irregular octagonal shape. A channel with its opening 10a facing the desired edge can be installed at a desired angle.

[0042] The polygonal band 16 of this embodiment is formed such that each of the sides 16u, 16r, 16d, and 16l corresponds to the side of the cross section of the channel 10 and is slightly larger than the other.

[0043] FIG. 4 is an explanatory diagram of various modes for installing the channel 10 in the polygonal band 16. When the channel 10 is installed and fixed in the polygonal band 16, the orientation of the opening 10a of the channel 10 within the polygonal band 16 can be selected in various ways. That is, the channel 10 can be fixed in any orientation, such as facing upward as shown in Figure 4(a), facing left as shown in Figure 4(b), facing downward as shown in Figure 4(c), or facing right as shown in Figure 4(d). It is also possible to eliminate the short sides and make the shape roughly rectangular, as in the polygonal band shown in Fig. 9. It is also possible to lengthen the short sides and install channels with openings 10a facing in accordance with each side of the octagon, making it possible to install the channels at even more precise angular positions as desired.

[0044] [Second embodiment] Figures 5 and 6 are explanatory diagrams and installation diagrams of a support bracket 12B according to the second embodiment, in which a hanging bracket 22 fixed to a hanging screw 18B with a nut 18c and a polygonal band 16 are connected by a through bolt 28 (corresponding to a "connecting member").

[0045] 5 and 6, hanging hardware 22 is a generally flat member having a notch 22a on one side through which hanging screw 18B is inserted and nut 18c is screwed onto it to secure it, and an insertion hole 22b on the other side for through-bolt 28. Notch 22a is cut into one end and presents a generally T-shape that widens at the back, and hanging screw 18B is inserted into notch 22a and nuts 18c, 18c are screwed onto it from above and below to secure hanging hardware 22 to hanging screw 18B.

[0046] Hanging hardware 22 is positioned horizontally, with arms 16b, 16b of polygonal band 16 protruding horizontally, and is clamped from above and below and secured with through-bolts 28. In the second embodiment, opening 10a of channel 10 is installed in polygonal band 16 facing upward, but the orientation of opening 10a can be set arbitrarily in any of the directions shown in FIG.

[0047] In addition, as shown in Figure 1, the support bracket 12B can be fixed to the channel 10 with the opening 10a of the channel 10 facing downward, and the support object 30 can be suspended by fixing it to the fixing member 30a with a hanging screw 18B supported by the support bracket 12B.

[0048] [Third embodiment] As shown in FIGS. 7 and 8, a support fitting 12C of the third embodiment is formed by connecting a plurality of polygonal bands 16, 16 to each other.

[0049] As shown in Figures 7 and 8, two (multiple examples) polygonal bands 16, 16 are connected together at a location other than the insertion holes of the pieces 16b, 16b. Specifically, the two polygonal bands 16, 16 are connected by crossing the sides on which the pieces 16b, 16b are not formed and connecting the bands with a connector 36 such as a rivet through a through-hole (not shown) formed in each band. In the example of Figure 7, a structure that allows for a certain degree of rotation when fastening the bands with the connector 36 such as a rivet makes it easy to select the relative angle and facilitate installation. Of course, the rotation of the connector 36 may be restricted. Alternatively, a modification in which the bands are connected by welding instead of rivets may be used.

[0050] [Fourth embodiment] As shown in FIGS. 9 and 10, a support fitting 12D of the fourth embodiment is connected to a fixing fitting 32 (see FIG. 1) fixed to a structural steel 24.

[0051] As shown in Figures 9 and 10, the support bracket 12D is equipped with a fixing bracket 32 ​​that is fixed to the structural steel 24, and the fixing bracket 32 ​​and the polygonal band 16 are connected with a through bolt 28 (corresponding to a "connecting member"), making it possible to fix the channel 10 to the structural steel 24 via the polygonal band 16.

[0052] The fixing bracket 32 ​​has a flange 24a of the structural steel 24 attached to a notch 32a formed in the side portion, and clamps and fixes the flange 24a in the notch 12a with a fixing screw 32b threaded into the upper portion.

[0053] The lower part of the fixing bracket 32 ​​is sandwiched between the pieces 16b, 16b, and a bolt 28 (bolt body 28a) is inserted into the mounting hole 32c, and the nut 28b is tightened to fix the polygonal band 16 that surrounds and supports the channel 10.

[0054] The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention. In the embodiments, a channel is given as an example of a long body that is asymmetric in cross section, but the long body of the present invention is not limited to this. For example, an L-shaped steel beam that has at least one horizontal or vertical surface in cross section is also included in the scope of the long body of the present invention. [Industrial Applicability]

[0055] The channel support method and support fittings of the present invention can be used to fix a channel to a main structure. [Explanation of symbols]
