Description

[Technical Field]

[0001] The present invention relates to a rod support and a method for attaching the rod support. [Background technology]

[0002] Suspension bolt supports for suspending suspension bolts from a ceiling slab or the like and fixing various electrical equipment (cables, piping, etc.) to the suspension bolts are known (see, for example, Patent Documents 1 to 4). The suspension bolt supports are fastened at any height relative to the suspension bolt and have a structure that supports electrical equipment such as cables and piping in any position via support fittings such as Pyrack clips. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5849424 [Patent Document 2] Patent No. 5102997 [Patent Document 3] Patent No. 5069193 [Patent Document 4] Japanese Utility Model Application Publication No. 61-162687 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-described suspension bolt support has the following problem. Specifically, when fastening a suspension bolt at a desired height by tightening a screw or the like, it is necessary to position the suspension bolt support with one hand and tighten the fastening bolt with the other. This requires the worker to use both hands. However, it is sometimes necessary to adjust the height of the suspension bolt support depending on its position relative to other materials, i.e., depending on the handling situation of the electrical equipment. In such cases, the worker must tighten the screw while adjusting the suspension bolt support to the appropriate height from an unstable stepladder or ladder, which is dangerous and cumbersome.

[0005] Furthermore, since metal fittings for hanging bolts are typically used in large numbers and are not removed once attached to the hanging bolts, there is also the problem that if the temporary fastening structure is complex, manufacturing costs increase, which in turn increases the overall product cost.

[0006] Therefore, there is a demand for a support for a suspension bolt that can be temporarily fastened to the suspension bolt with a simple operation and can be manufactured at low cost. [Means for solving the problem]

[0007] The rod support according to this embodiment can be detachably attached to any position on the side of a rod. The rod support includes a main body formed in the shape of a generally rectangular cylinder with a bottom, a clamping section housed within the main body and configured as a groove with a generally U-shaped cross section, a fastening bolt fastening the main body and the clamping section together, and an elastic member biasing the main body and the clamping section in a direction to clamp a rod placed therebetween. The leading edges of the side plates of the main body are notched in a concave shape, and the groove plates of the clamping section are configured in a hook shape. A rod is introduced between the concave edges of the side plates of the main body and the hook-shaped groove plates of the clamping section, and the rod support is pushed onto the introduced rod and slid to temporarily secure the rod support to the rod. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a suspension bolt support that can be temporarily fixed to a suspension bolt with a simple operation and can be manufactured at low cost. [Brief explanation of the drawings]

[0010] (First embodiment) 1 and 2 respectively show how a suspension bolt support 10 according to a first embodiment of the present invention is used. As shown in FIGS. 1 and 2, the suspension bolt support 10 is fixed to a suspension bolt B when in use. For example, as shown in FIG. 1, a Pyrack clip Q is attached to the suspension bolt support 10 fixed to the suspension bolt B, and an electric wire pipe P (electrical equipment) is passed through the Pyrack clip Q and fixed with a bolt and nut. Also, as shown in FIG. 2, a cable support fitting S, which is a steel rod curved into a semicircular shape, is attached via a screw to the suspension bolt support 10 fixed to the suspension bolt B, and a cable C is laid through the cable support fitting S and fixed with a cable tie.

[0011] As shown in Figures 3 to 8, the suspension bolt support 10 houses an auxiliary metal fitting (clamping portion) 60 configured as a groove frame with a roughly U-shaped cross section inside a main metal fitting (main body) 20 configured as a roughly rectangular cylinder with a bottom, and the main body 20 and clamping portion 60 are fastened to each other's bottom plates with a fastening bolt 90. The leading edges of the upper and lower side plates of the main body 20 are notched in a concave shape. The upper and lower groove plates of the clamping portion 60 are configured in a hook shape. A suspension bolt B is introduced between the concave edges of the upper and lower side plates of the main body 20 and the hook-shaped groove plate of the clamping portion 60. The main body 20 and the clamping portion 60 are biased by an elastic member in a direction that clamps the suspension bolt B. The elastic member allows the suspension bolt support 10 to be temporarily fastened to the suspension bolt B in a temporary fastening state in which the fastening bolt 90 is not fully tightened. Typically, these parts are made of metal, but all or some of the parts may be made of hard resin. In detail, the suspension bolt support 10 is configured as follows.

[0012] The main body 20 is configured as a substantially rectangular cylinder with a bottom. Specifically, the main body 20 includes a rectangular plate-shaped main body base 30, a pair of plate-shaped bracket attachment portions 40, 50 provided on both short-side edge portions of the main body base 30, and a pair of plate-shaped support portions 31, 32 provided on both long-side edge portions. Typically, the main body base 30, the bracket attachment portions 40, 50, and the support portions 31, 32 that constitute the main body 20 are formed by bending, deforming, cutting, drilling, etc., a single sheet of metal.

[0013] An insertion hole 30a into which the threaded portion of the fastening bolt 90 is inserted is formed in the main body base portion 30. As shown in FIG. 8, the insertion hole 30a has an oval shape and is provided at a position offset in the longitudinal direction from the center position of the main body base portion 30. Note that the insertion hole 30a is not limited to an oval shape and may be rectangular. By making the insertion hole 30a oval or rectangular, the range of motion of the clamping portion 60 relative to the main body portion 20 can be expanded, the clamping portion 60 can be tilted relative to the main body portion 20, and its position can be adjusted. This allows the clamping portion 60 to be used with different diameters of the hanging bolt B without requiring design changes.

[0014] The support portions 31 and 32 are each formed by being bent at a right angle to the main body base portion 30. Gently arc-shaped recesses (first recesses) 31a and 32a are formed at the tip edges of the support portions 31 and 32, respectively. The diameter of the arc of the recesses 31a and 32a is larger than the diameter of the hanging bolt B.

[0015] The bracket mounting portions 40, 50 are each formed by being bent at a right angle to the main body base portion 30. A bracket mounting hole 40a, 50a is formed in the center of each bracket mounting portion 40, 50. The bracket mounting holes 40a, 50a can be replaced with various structures, such as a screw hole or a protrusion, depending on the application of the suspension bolt support 10.

[0016] Plate-shaped guide portions 41, 42 are provided on both side edges of the bracket mounting portion 40. The guide portions 41, 42 are each formed by being bent at a right angle to the bracket mounting portion 40. The guide portions 41, 42 are located outside the support portions 31, 32, and their leading edges reach the first recesses 31a, 32a of the support portions 31, 32. The corner edges on the leading edge side of the guide portions 41, 42 corresponding to the leading edge side of the main body 20 are cut out in a gentle curve, and guide edges 41a, 42a that continue to the first recesses 31a, 32a of the support portions 31, 32 are formed.

[0017] Plate-shaped guide portions 51, 52 are provided on both side edges of the bracket mounting portion 50. The guide portions 51, 52 are each formed by being bent at a right angle to the bracket mounting portion 50. The guide portions 51, 52 are located outside the support portions 31, 32, and their leading edges reach the first recesses 31a, 32a of the support portions 31, 32. The leading edges of the guide portions 51, 52 are provided with outer recesses 51a, 52a that are recessed in an arc shape. The diameter of the arc of the outer recesses 51a, 52a is larger than the diameter of the hanging bolt B.

[0018] 5, 6, and 7, the clamping portion 60 is configured as a groove frame having a U-shaped cross section. The depth of the clamping portion 60 is approximately equal to the depth of the inner space of the main body portion 20, and the width of the clamping portion 60 is approximately equal to the depth of the inner space of the main body portion 20. This configuration makes it shorter than the width of the inner space, thereby increasing the range of movement of the clamping part 60 in the inner space of the main body part 20, and enabling it to tilt and slide relative to the main body part 20.

[0019] Specifically, the clamping unit 60 includes a rectangular clamping base 70 and a pair of plate-shaped engaging portions (hook plates) 80 provided on both edges of the long sides of the clamping base 70. As shown in FIG. 6, a screw hole 71 is formed in the clamping base 70 to be threadedly engaged with the thread of a fastening bolt 90. The screw hole 71 is provided at a position offset in the longitudinal direction from the center of the clamping base 70. The insertion hole 30a formed in the main body base 30 and the screw hole 71 formed in the clamping base 70 are both provided at positions offset from the center. This prevents the clamping unit 60 from being oriented incorrectly during the assembly process of inserting the clamping unit 60 into the main body 20 and fastening it to the fastening bolt 90, thereby enabling efficient assembly. Hook-shaped hook pieces 81, 82 are formed on the tip ends of the pair of engaging portions 80, respectively. The hook pieces 81, 82 are curved inward and downward, and their respective inner edges form gently arc-shaped hook portions (second recesses) 81a, 82a. The outer edges of the hook pieces 81, 82 form gently curved guide edges 81b, 82b. The guide edges 81b, 82b make it possible to easily guide the suspension bolt B between the guide edges 41a, 42a on the main body 20 side and the hook pieces 81, 82 on the clamping portion 60 side. The diameter of the arc of the hook portions 81a, 82a is larger than the diameter of the suspension bolt B.

[0020] The first recesses 31a, 32a of the main body 20, the hooks 81a, 82a of the clamping portion 60, and the outer recesses 51a, 52a form a hollow portion H for holding or passing the suspension bolt B.

[0021] The main body 20 and the clamping part 60 are fastened together at their bottom plates by a fastening bolt 90. Specifically, the fastening bolt 90 is inserted into the insertion hole 30a in the main body base 30, and its threaded part is screwed into the screw hole 71 in the clamping base 70. Therefore, the clamping part 60 can move towards and away from the main body 20 along the axial direction of the fastening bolt 90 within the range of the length of the fastening bolt 90.

[0022] The suspension bolt support 10 includes an elastic member that biases the main body 20 and the clamping portion 60 in a direction that brings them closer to each other. The direction in which the main body 20 and the clamping portion 60 move closer to each other corresponds to the direction in which the gap between the hollow portion H between the first recesses 31a, 32a and the second recesses 81a, 82a narrows. As shown in FIGS. 3, 4, and 5, a conical coil spring (elastic member) 95 is interposed between the head 91 of the fastening bolt 90 and the main body base 30 of the main body 20. The configuration is not limited to the above, as long as it can bias the main body 20 and the clamping portion 60 in a direction that narrows the gap between the hollow portion H between the first recesses 31a, 32a and the second recesses 81a, 82a. For example, the fastening bolt 90 may be inserted from the clamping portion 60 side. In addition, the conical coil spring 95 can be replaced with a tension coil spring interposed between the main body base portion 30 and the clamping base portion 70.

[0023] Hereinafter, the tightening of the fastening bolt 90 until the conical coil spring 95 is slightly crushed will be referred to as pre-tightening, and the tightening of the fastening bolt 90 until the conical coil spring 95 is completely crushed, or until it cannot be tightened any further, will be referred to as final tightening.

[0024] The suspension bolt support 10 according to this embodiment is used with the fastening bolt 90 temporarily fastened. In this state, the conical coil spring 95 biases the head 91 of the fastening bolt 90 in a direction that moves the head 91 away from the main body base 30. Because the clamping base 70 is threadedly engaged with the fastening bolt 90, the clamping base 70 is pulled toward the main body base 30 (downward in FIG. 5 ) and overlaps and adheres tightly to the main body base 30. At this time, the hollow portion H between the first recesses 31a, 32a and the second recesses 81a, 82a is configured to be narrower than the diameter of the suspension bolt B.

[0025] The suspension bolt support 10 configured in this manner is used as shown in Figures 9, 10, and 11. One feature of the suspension bolt support 10 according to this embodiment is that it has a structure that allows the suspension bolt support 10 to be temporarily fixed to the suspension bolt simply by pushing the suspension bolt support 10 onto the suspension bolt. The principle behind the suspension bolt support 10 being temporarily fixed simply by pushing it onto the suspension bolt is as follows.

[0026] 9(a), the worker operates the suspension bolt support 10 so that the suspension bolt B is positioned between the guide edges 41a, 42a on the main body 20 side and the hook pieces 81, 82 on the clamping portion 60 side, and then pushes the suspension bolt support 10 onto the suspension bolt B. Then, the clamping portion 60 is pushed by the suspension bolt B, sliding in the direction of arrow M1 while rotating in the direction of arrow R1 around the end portion P1 of the clamping base portion 70 as a fulcrum. In this way, the suspension bolt B can enter the hollow portion H along the guide edges 41a, 42a while pushing the clamping portion 60.

[0027] 9(b), when the suspension bolt support 10 is slid relative to the suspension bolt B, the clamping portion 60 is lifted in the direction of arrow M2 by the suspension bolt B. This allows the suspension bolt B to be accommodated in the hollow portion H.

[0028] As shown in FIG. 9(c), the first recesses 31a and 32a of the main body 20 engage with one side of the circumferential surface of the hanging bolt B housed in the hollow portion H, and the second recesses 81a and 82a of the clamping portion 60 engage with the other side of the circumferential surface of the hanging bolt B, so that the main body 20 and the clamping portion 60 firmly clamp the circumferential surface of the hanging bolt B from both sides. The holding force at this time is due to the elastic force of the conical coil spring 95, and the fastening bolt 90 is temporarily tightened so that the force is sufficient to prevent the hanging bolt support 10 from falling off the hanging bolt B due to its own weight. Therefore, as will be explained in FIG. 10, the worker can easily adjust the height of the hanging bolt support 10. The holding force can be adjusted by the degree to which the fastening bolt 90 is tightened. Therefore, if you want to increase the force with which the suspension bolt support 10 is temporarily fastened to the suspension bolt B, you can simply tighten the fastening bolt 90 a little, and if you want to decrease the force with which the suspension bolt support 10 is temporarily fastened to the suspension bolt B, you can simply loosen the fastening bolt 90 a little. The ability to adjust this temporary fastening force is also an important factor in being able to accommodate various thicknesses and weights.

[0029] Since the insertion hole 30a is oval and the outer width of the clamping portion 60 is narrow relative to the width of the interior of the main body 20, the clamping portion 60 can be slid along the arrow M1. This sliding movement is perpendicular to the direction in which the conical coil spring 95 urges the clamping portion 60 toward the main body 20, and does not require a large force. Furthermore, since the insertion hole 30a is oval, the clamping portion 60 can be tilted relative to the main body 20. Since the position at which the fastening bolt 90 is threaded in the clamping base 70 is offset from the center to the side opposite the direction in which the fastening bolt 90 is pushed in by the hanging bolt B, when the hanging bolt B is pressed against the hook pieces 81, 82, the principle of leverage comes into play and the clamping portion 60 can be rotated in the direction of the arrow R1 with little force.

[0030] In this way, the worker can temporarily fasten the suspension bolt support 10 to the suspension bolt B with a simple operation of simply pushing and sliding the suspension bolt support 10 onto the suspension bolt B, and with little force. The above operation is simple and can be done with one hand, which contributes to improving the worker's work efficiency.

[0031] The state in which the suspension bolt support 10 has been temporarily fastened to the suspension bolt B can be released by the following operation. That is, as shown in FIG. 10 , by pressing the head 91 of the fastening bolt 90 with a force F that resists the biasing force of the conical coil spring 95, the clamping portion 60 is moved away from the main body 20, and the hollow portion H formed by the main body 20 and the clamping portion 60 can be widened. This allows the suspension bolt support 10 to be released from the state in which it has been temporarily fastened to the suspension bolt B. Of course, the above operation may also be performed when temporarily fastening the suspension bolt support 10 to the suspension bolt B. That is, instead of pressing the suspension bolt support 10 against the suspension bolt B, the head 91 of the fastening bolt 90 may be pushed in as described above, and the hollow portion H may then be widened, and the suspension bolt B may then be introduced into the hollow portion H. When an operator wants to adjust the position of the suspension bolt support 10 temporarily fixed to the suspension bolt B, the operator presses the head 91 of the fastening bolt 90 to release the temporary fixation, then moves the suspension bolt support 10 to the desired position, and releases his / her hand from the head 91 to temporarily fix the suspension bolt support 10 to the suspension bolt B.

[0032] Furthermore, for fine adjustment of the suspension bolt support 10, the worker may perform the following operation. The suspension bolt support 10 is temporarily fastened to the suspension bolt B with a clamping force sufficient to prevent the suspension bolt support 10 from falling off the suspension bolt B, and the first recesses 31a, 32a and the second recesses 81a, 82a have a plate thickness greater than the thread groove of the suspension bolt B and are not completely fitted into the thread groove of the suspension bolt B. Therefore, in the temporarily fastened state, the worker can adjust the position of the suspension bolt support 10 simply by moving the suspension bolt support 10 in the axial direction of the suspension bolt B with a force that resists the clamping force, without the need to press the fastening bolt 90. Furthermore, by configuring the plate thickness of the first recesses 31a, 32a and the second recesses 81a, 82a to be thinner than the thread groove of the hanging bolt B so that the first recesses 31a, 32a and the second recesses 81a, 82a fit completely into the thread groove of the hanging bolt B, it is possible to make the hanging bolt support 10 even less likely to fall off from the hanging bolt B.

[0033] As shown in FIG. 11 , once the installation position of the suspension bolt support 10 is determined, the fastening bolt 90 is tightened from its pre-tightened state until it is fully tightened. At this time, the suspension bolt support 10 is temporarily fastened to the suspension bolt B, and both the main body 20 and the clamping portion 60 are fixed by the elastic force of the conical coil spring 95. This allows the worker to tighten the fastening bolt 90 without holding the main body 20 with their hands. This contributes to improved workability. By fully tightening the fastening bolt 90, the head 91 of the fastening bolt 90 does not move even when pressed, so the main body 20 and the clamping portion 60 are fixed (fully fastened) in the positional relationship they had in the pre-tightened state. The main body 20 and the clamping portion 60 are firmly fastened by the fastening bolt 90 with the suspension bolt B sandwiched between them. The fastening force at this time is much stronger than the biasing force of the conical coil spring 95. Therefore, the suspension bolt support 10 can be fastened to the suspension bolt B with sufficient force.

[0034] Furthermore, since the conical coil spring 95 is exposed on the surface of the suspension bolt support 10, it is possible to check whether the suspension bolt support 10 is in a permanently or temporarily fixed state relative to the suspension bolt B simply by looking at the conical coil spring 95.

[0035] With the suspension bolt support 10 according to the first embodiment described above, the worker can easily temporarily fasten the suspension bolt B and adjust the height with one hand, and once the height position is determined, the worker can firmly fasten the suspension bolt B by fully tightening the fastening bolt 90. This improves work efficiency. Furthermore, the number of parts is small, and the main body 20 and clamping portion 60 can each be formed from a single piece of sheet metal, thereby reducing manufacturing costs.

[0036] Although the conical coil spring 95 is used as an example of the elastic member that biases the main body base 30 and the head 91 of the fastening bolt 90 in the direction of separating them from each other from the viewpoint of the stability of the pressing operation by the operator, other elastic members such as a leaf spring may also be used. Also, for example, a part of the main body base 30 or the clamping base 70 may be cut out and bent to bias the fastening bolt 90.

[0037] In the first embodiment of the suspension bolt support 10, a conical coil spring 95 is placed between the main body 20 and the head 91 of the fastening bolt 90, and the force attracting the clamping portion 60 to the main body 20 is used to clamp the suspension bolt B placed between the main body 20 and the clamping portion 60. However, the shape of the main body 20 and the clamping portion 60 may be configured so that the conical coil spring 95 is placed between the main body base 30 and the clamping base 70, and the force moving the clamping portion 60 away from the main body 20 is used to clamp the suspension bolt B placed between the main body 20 and the clamping portion 60.

[0038] The suspension bolt support 10 according to the first embodiment clamps the suspension bolt B between the main body 20 and the clamping portion 60 to temporarily secure the suspension bolt B. Therefore, the suspension bolt support 10 can be used as a rod support that can temporarily secure rod-shaped materials, such as round steel bars and square steel bars, that do not have thread grooves. In this case, the clamping force can be strengthened by increasing the contact area between the main body 20 and the clamping portion 60 and the rod-shaped material, thereby increasing the frictional force generated between them. The same effect can also be achieved by attaching pads to the portions of the main body 20 and the clamping portion 60 that come into contact with the rod-shaped material to increase the frictional force generated between them.

[0039] The suspension bolt support 10 according to the first embodiment is configured such that both the main body 20 and the clamping portion 60 are provided with recesses that receive the circumferential surface of the suspension bolt B. This allows the suspension bolt B, guided between the first recesses 31a, 32a of the main body 20 and the second recesses 81a, 82a of the clamping portion 60, to be retained and stably clamped. Furthermore, lateral movement of the clamped suspension bolt B is restricted, reducing the possibility of the suspension bolt support 10 falling off the suspension bolt B. This effect can be achieved by providing a recess in at least one of the main body 20 and the clamping portion 60. Furthermore, as long as the suspension bolt B is clamped between the main body 20 and the clamping portion 60, it is not necessary to provide recesses in both the main body 20 and the clamping portion 60.

[0040] (Second embodiment) FIG. 12 is an exploded perspective view showing a suspension bolt support 100 according to a second embodiment of the present invention. Like the suspension bolt support 10 described above, the suspension bolt support 100 can be attached to the suspension bolt B at any height. The major difference between the suspension bolt support 100 according to the second embodiment and the suspension bolt support 10 according to the first embodiment is the different shape of the hook piece of the clamping portion. The following description will focus on the clamping portion 150 of the suspension bolt support 100 according to the second embodiment. Note that the main body 110 of the suspension bolt support 100 according to the second embodiment will be described with reference numerals assigned only to necessary parts.

[0041] The clamping unit 150 includes a rectangular plate-shaped clamping base 160 and a plate-shaped engaging unit 170 formed on the edge of the long side of the clamping base 160. A screw hole 161 is provided in the center of the clamping base 160. The engaging unit 170 has an engaging plate 171, and a hole 171a is formed in the engaging plate 171. A pair of hook pieces 172 is formed on the tip side of the engaging plate 171. The pair of hook pieces 172 are curved inward and downward, and each inner surface forms a gently arc-shaped hook portion (second recess) 172a, and the outer surface forms a gently curved guide edge 172b. The diameter of the arc of the hook portion 172a is larger than the diameter of the hanging bolt B.

[0042] The hook portion 172a of the clamping portion 150 and the first recesses 121a and 122a of the main body portion 110 form a hollow portion H for holding or passing the suspension bolt B.

[0043] The suspension bolt support 100 according to the second embodiment can be temporarily fixed to the suspension bolt B simply by pushing it into the suspension bolt B, using the same principle as the suspension bolt support 10 according to the first embodiment. In addition, the position of the suspension bolt support 100 temporarily fixed to the suspension bolt B can be adjusted with a simple operation. Furthermore, the suspension bolt support 100 can be permanently fixed to the suspension bolt B by finally tightening the fastening bolt 190. In this way, the suspension bolt support 100 according to the second embodiment exhibits the same effects as the suspension bolt support 10 according to the first embodiment.

[0044] The present invention is not limited to the above-described embodiments, and various modifications can be made in the implementation stage without departing from the spirit of the invention. Furthermore, the embodiments may be implemented in appropriate combinations, in which case the combined effects can be obtained. Furthermore, the above-described embodiments include various inventions, and various inventions can be extracted by combining selected elements from the disclosed elements.
