Description

  The present invention relates to a support tool for an arrangement body that is fixed to a rod-like body such as a suspension bolt and supports an arrangement body such as a piping material or an electric energy type box.

  Conventionally, pipes such as electric pipes and water supply pipes, wiring materials such as cables, electric energy type boxes, fire detectors, etc., are used as rods such as suspension bolts, which are construction materials, using support tools. Installed. As this type of support, for example, one disclosed in Japanese Utility Model Publication No. 3-53541 is disclosed. FIG. 14 shows an electric wire connection box for fixing a suspension bolt as a support for an arrangement body described in the above publication. In FIG. 14, an electric wire connection box 81 includes a fixing portion 82 for holding and fixing a suspension bolt 61 suspended from a ceiling or the like, a hooking portion 83 as a support portion for supporting a wire connection portion so as not to drop, And a protective cover 84 for protecting the connection points. The fixing portion 82 has two clamp members 85 and 86 that are open along the axial direction of the suspension bolt 61 and whose inner surface has a curved surface that matches the outer shape of the suspension bolt 61. Screws 87 are inserted into each other, and nuts 88 are tightened, whereby suspension bolts 61 are clamped and fixed.

  However, the clamp members 85 and 86 of the electric wire connection box described in the above publication have side end portions 85a and 86a that are opposed to each other in a straight line, and the engagement amount with the outer peripheral surface of the suspension bolt 61 is relatively large. Therefore, when a large load is applied to the latching portion 83 or a large force is applied such as pulling the latching portion 83 in the horizontal direction, the distance between the side end portions 85a and 86a is increased and the suspension bolt 61 There is a risk of removal.

On the other hand, in Japanese Patent Laid-Open No. 10-318436, as shown in FIG. 15, protrusions 96 projecting in the circumferential direction at the side end portions 94 and 95 at the tips of the two clamp pieces 92 and 93, respectively. 97 is formed, and the projections 91 are arranged in an interlocking manner with the protrusions shifted from each other in the axial direction of the pipe 62. Since this clamp device 91 has a large engagement amount with the outer peripheral surface of the pipe 62 because the protrusions of the respective clamp pieces protrude in the circumferential direction, the clamp members 85 of the wire connection box 81 shown in FIG. From 86, the resistance and deterrence against the pulling out from the pipe 62 are large, and it is difficult to pull out from the pipe 62.
Japanese Utility Model Publication No. 3-53541 JP 10-318436 A

  However, when the clamp device 91 described in Patent Document 2 is removed from the pipe 62, the connection bolt 98 connecting the two clamp pieces 92 and 93 is loosened and removed, or the connection bolt 98 is sufficiently tightened. The pipe 62 cannot be pulled out from the space between the side ends unless the distance between the side end 94 of the clamp piece 92 and the side end 95 of the clamp piece 93 is greatly expanded. Cannot be removed from the pipe 62. In addition, when the clamp device 91 is attached to the pipe 62 and fixed, if the clamp piece 91 and the clamp piece 93 are assembled in advance through the connecting bolt 98, the same procedure is performed. The connecting bolt 98 must be removed, or the tightening of the connecting bolt 98 should be sufficiently loosened to greatly expand the distance between the side end portion 94 of the clamp piece 92 and the side end portion 95 of the clamp piece 93. The pipe 62 cannot pass through the space between them. Then, after the pipe 62 is inserted into the clamp piece 92 and the clamp piece 93, even when the connection bolt 98 is tightened again, the connection piece 98 must be rotated a number of times and screwed for a corresponding distance unless the connection bolt 98 is screwed. 93, the pipe 62 cannot be clamped and fixed. For this reason, the clamping device 91 must be screwed up by a considerable distance by loosening or tightening the connecting bolt 98 many times when attaching / detaching to / from the pipe 62, which requires a great deal of labor and time. It cost.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a support for an arrangement body that can be prevented from being removed from the rod-shaped body and can be easily attached to and detached from the rod-shaped body in a short time. It is.

The support for the arrangement body according to claim 1 includes a pair of holding pieces for holding the rod-like body, a support member connected to the holding piece and supporting the arrangement body, the pair of holding pieces, and the support member . A pair of clamping pieces, wherein the pair of clamping pieces sandwich the rod-shaped body, and the side end portions facing each other incline linearly with respect to the axial direction of the rod-shaped body , and the coupling By the operation of the tool, the distance between the pair of side end portions in the direction orthogonal to the rod-shaped body is changed to a size through which the rod-shaped body can pass.

  Thereby, since the side edge part which mutually opposes a pair of clamping piece inclines linearly with respect to the axial direction of a rod-shaped body, the engagement length of the circumferential direction with a rod-shaped body can be enlarged. That is, the pair of sandwiching pieces can form overlapping portions in the circumferential direction of the rod-like body in a state where they are shifted from each other in the axial direction of the rod-like body, not in the stacking direction, Since the body is clamped, the circumferential engagement length with the rod-shaped body is large. As a result, even when an external force is applied to the support tool, the support tool can be prevented from being detached from the rod-shaped body.

  In addition, since the side end portions of the pair of sandwiching pieces are linearly inclined with respect to the axial direction of the rod-shaped body, the side ends of the pair of sandwiching pieces can be removed when the support tool is attached to and removed from the rod-shaped body. If the support is rotated by a predetermined angle and tilted so that the portion is parallel to the axis of the rod-shaped body, the distance between the side ends of the pair of sandwiching pieces is expanded larger than the outer diameter of the rod-shaped body and passes through the rod-shaped body. The amount of expansion of the interval necessary for the reduction is small. As a result, the number of rotations can be reduced to loosen the tightening of the connecting bolt, and the screwing distance can be shortened.

Here, the rod-shaped body corresponds to a suspension bolt that is a construction material. There are suspension bolts that are suspended from a double ceiling or the like, and those that are disposed in an inclined state as a steady rest.
Each side end portion of the pair of sandwiching pieces is formed in a straight line shape, and the straight line shape includes those in which some unevenness is formed without departing from the gist of the present invention.
Although it is desirable that each side edge part of a pair of clamping piece is mutually parallel, it is not necessarily restricted to this.
The connector is generally composed of a bolt and a nut, but can be composed only of a bolt.

  The support of the arrangement body according to claim 2 is formed such that the side end portions of the pair of holding pieces are parallel to each other in a state where the rod-like body is held.

  According to the first aspect of the present invention, since the opposing side end portions of the pair of sandwiching pieces are inclined linearly with respect to the axial direction of the rod-shaped body, the circumferential engagement length with the rod-shaped body is increased. Can be prevented from being removed from the rod-shaped body, and when attaching to and detaching from the rod-shaped body, the connecting tool can be loosened or tightened by rotating the support tool at a predetermined angle with respect to the rod-shaped body. By reducing the number of rotations and the amount of screwing, the time required for fixing and removing the support can be shortened, and these operations can be easily performed.

  In the invention of claim 2, since the side end portions of the pair of sandwiching pieces are parallel to each other, both effects of preventing the removal from the rod-shaped body and improving workability of fixing to the rod-shaped body and removal are balanced. Obtainable.

Hereinafter, a support for an arrangement body according to an embodiment of the present invention will be described with reference to the drawings. In this embodiment, the suspension bolt arrange | positioned by the ceiling of a building etc. as a rod-shaped body is illustrated.
In FIG. 1 to FIG. 5, the support 1 is fixed to the suspension bolt 61 in order to support the piping material 72 as the arrangement body 71 to the suspension bolt 61 as a construction material. The support 1 includes a fixing member 11 fixed to the suspension bolt 61, a support member 21 connected to the fixing member 11 and supporting the arrangement body 71, and a connection connecting the fixing member 11 and the support member 21. The tool 31 is provided. Hereinafter, each component will be described in detail.

  As shown in FIG. 3, the fixing member 11 is composed of a pair of sandwiching pieces 12 and 13 whose one end is curved in an arc shape by pressing a metal plate material such as a substantially rectangular plate-shaped steel plate. As shown in FIGS. 3A and 3B, the sandwiching pieces 12 and 13 are formed in the same manner except for the position of a through-hole 17 to be described later. In other words, the pair of sandwiching pieces 12 and 13 are symmetric except for the shape of one end. Each clamping piece includes a fixing portion 14 and a fixing portion 15 that are fixed to the suspension bolt 61, and a connecting portion 16 that is connected to the support member 21. The inner surface of each fixing portion is formed into a curved surface having substantially the same curvature as the outer peripheral surface of the suspension bolt 61.

  And as shown in FIG.3 (d), as for the fixing | fixed part 14 in one clamping piece 12, the side edge part 14a facing the fixing | fixed part 15 has the continuous protrusion length of a horizontal direction toward a lower end from an upper end. It is inclined in a straight line shape when viewed from the side, and changes in a spiral shape with respect to the suspension bolt 61. Here, the side view means a state in which the opposing portions of the pair of sandwiching pieces 12 and 13 are viewed from the side of the suspension bolt 61. Further, the fixing portion 15 in the other sandwiching piece 13 has a side end portion 15a inclined in a straight line shape in a side view as the protrusion length in the horizontal direction continuously decreases from the upper end to the lower end. In the state where both the sandwiching pieces sandwich the suspension bolt 61, the lower end corner portion 14b of the side end portion 14a of the sandwiching piece 12 and the upper end corner portion 15b of the side end portion 15a of the sandwiching piece 13 are both the center of the suspension bolt 61. Extends beyond the line. In addition, since the side end portion of each clamping piece is formed by cutting an arc-shaped bent portion of the fixing portion of each clamping piece obliquely with respect to the axial direction of the suspension bolt 61, FIG. As shown in (b), when viewed from the side, it has a curved shape slightly bulging outward. Here, it is assumed that the end portions on both sides include, for example, those in which a large number of extremely small irregularities are formed along the longitudinal direction. Furthermore, in the state fixed to the suspension bolt 61, the side end portion 14a of the holding piece 12 and the side end portion 15a of the holding piece 13 are parallel to each other in an oblique direction and separated by a certain width. In addition, a rib 14c for reinforcement is formed on the outer wall surface of the fixed portion 14, and a rib 15c is formed on the outer wall surface of the fixed portion 15, and deformation in this portion is prevented.

  A through hole 17 through which the connecting bolt 32 passes is formed in the connecting portion 16 of the fixing member 11. A rectangular detent protrusion 18 that abuts a side surface of a hexagon nut 33 described later is provided on the periphery of the through-hole 17 of one clamping piece 12. Furthermore, a bent piece 19 that is bent 90 degrees toward the opposite side is formed at each of the upper and lower ends of the substantially intermediate portion between each fixed portion and the connecting portion 16, and the bent piece 19 is a curved surface of the fixed portion. Thus, the suspension bolt 61 functions as a misalignment prevention unit that prevents the suspension bolt 61 from shifting in a direction perpendicular to the axis thereof, and the support member 21 is prevented from rotating beyond a certain angle range with respect to the fixed member 11. Function as a stopper. In addition, a U-shaped notch 20a is formed in the peripheral edge portion 20 adjacent to the bent piece 19 at the lower end portion of each sandwiching piece, and an end surface 20b on the connecting portion 16 side of the notch 20a is a rotation of a support member 21 described later. It can come into contact with the movement preventing portion 27.

  On the other hand, as shown in FIG. 4, the support member 21 is integrally formed with a connecting vertical plate portion 23 having a constant width along the length direction at the center in the width direction of the support plate portion 22 formed in an elongated substantially rectangular plate shape. An insertion hole 24 and an insertion hole 25 through which the connection bolt 32 is inserted are provided at one end portion and an intermediate portion in the longitudinal direction at the upper portion of the connection vertical plate portion 23, respectively. A peripheral wall 26 having a fixed height is provided on the periphery of the support plate portion 22 along the periphery. However, U-shaped notch openings 26 a are formed on both sides of the connecting vertical plate portion 23 at the end of the peripheral wall 26 on the insertion hole 24 side. As shown in FIG. 5, the lower end portion of the notch opening 26 a is a step portion 26 b that slightly protrudes downward from the bottom surface of the support plate portion 22, and this step portion 26 b is a notch of the peripheral edge portion 20 of each clamping piece. The rotation prevention part 27 which the end surface 20b in 20a contact | abuts is comprised.

  Furthermore, a groove hole 28 is formed along the longitudinal direction in the intermediate portion of the back surface of the support plate 22 along the longitudinal direction, and this groove hole 28 has a width smaller than the screw outer diameter of a screw for fixing a saddle to be described later. It is formed and can be screwed in. The support plate portion 22 is provided with four rectangular square holes 29 penetrating inward and outward at intervals in the longitudinal direction on both sides of the slot 28. The square hole 29 is inserted with a binding band 73 or the like, and the arrangement body 71 is held by the support plate portion 22 by the binding band 73 or the like. Further, in the support plate 22, a misalignment prevention recess 30 that is slightly recessed in the shape of a circular arc is formed at an intermediate position of each square hole 29, and a placement member 71 such as a piping material 72 and a cable is positioned in the support plate 22. It is held at a fixed position without shifting.

  A hexagon bolt is used as the coupling bolt 32 as the coupling tool 31. The coupling bolt 32 penetrates the through holes 17 of the pair of holding pieces 12, 13, the insertion holes 24 of the support member 21, and the like, and is tightened with a hexagon nut 33. The sandwiching pieces 12 and 13 and the support member 21 are connected to each other and are detachably attached to the pair of sandwiching pieces 12 and 13 and the support member 21. Further, a plain washer 34 and a spring washer 35 are externally fitted to the threaded portion of the connecting bolt 32, and tightening by the connecting bolt 32 is strengthened. However, these flat washers 34, spring washers 35, etc. are not necessarily required. When the two are connected by the connecting bolt 32, the hexagonal nut 33 is held at a constant angle by bringing the side surface of the hexagonal nut 33 into contact with the anti-rotation protrusion 18 provided on one clamping piece 12. Therefore, it is not necessary to hold the hexagon nut 33 with one hand, and the tightening operation can be performed easily.

Next, the support of the arrangement body by the support 1 configured as described above will be described.
First, when the suspension bolt 61 is suspended from the ceiling or the like and the support member 21 cannot rotate about the connecting bolt 32, the piping material 72 as the arrangement body 71 is supported at a fixed position. The support form shown in FIG. That is, the support 1 is fixed to the suspension bolt 61 in a state of extending in the horizontal direction perpendicular to the axis thereof. At this time, the fixing portions of the pair of sandwiching pieces 12 and 13 are fixed to the suspension bolts 61 with their side edges parallel to an oblique direction and spaced apart at a constant interval, as shown in FIG. The In addition, the support tool 1 of FIG. 5 is turned upside down with respect to the support tool 1 of FIGS.

  In this support mode, the end surface 20b of the notch 20a formed on the peripheral edge 20 at the upper end of each clamping piece abuts against and interferes with the rotation blocking portion 27 of the support member 21, so that the support member 21 is connected to the shaft of the connecting bolt 32. Rotating clockwise about the heart is prevented. On the other hand, since the end portion of the connecting vertical plate portion 23 of the support member 21 contacts the bent piece 19 at the upper end of each clamping piece, the support member 21 is prevented from rotating counterclockwise. For these reasons, the support member 21 is prevented from rotating clockwise and counterclockwise about the axis of the connecting bolt 32 with respect to the fixed member 11, and is thus held at a constant horizontal position. As a result, the two pipe members 72 are also supported in a fixed posture that is always juxtaposed in the horizontal direction without shaking.

  Next, the suspension bolt 61 is provided obliquely as an anti-sway member, and the two piping members 72 are juxtaposed to allow the support member 21 to rotate around the connecting bolt 32 during mounting. In the case of supporting, the support form shown in FIG. 5B, the support 1 shown in FIG. 5B is connected to the support member 21 by integrating the pair of sandwiching bodies 12 and 13 of the fixing member 11 as compared with the support form shown in FIG. The difference is that the bolt 32 is attached by being inverted 180 degrees in the vertical direction around the axis of the bolt 32.

In FIG. 5B, the support member 21 slightly lowers the connection bolt 32, thereby lowering the lower surface of the connection vertical plate portion 23 of the support member 21 from a state perpendicular to the suspension bolt 61 around the axis of the connection bolt 32. Is pivotable clockwise until it comes into contact with the bent piece 19 at the lower end of each clamping piece.
In order to support the arrangement body 71 on the support 1, the support member 21 is rotated in the vertical direction in a state where the fixing member 11 is fixed to the inclined suspension bolt 61, and when the horizontal position is reached, the connecting bolt 32. Tighten firmly. Thereby, the two piping materials 72 are supported by the support 1 in the state juxtaposed in the horizontal direction. As a result, when the suspension bolt 61 suspended vertically and the suspension bolt 61 suspended obliquely are provided in the piping path of the piping material 72, the two piping materials 72 are The entire piping path can be supported by each suspension bolt 61 in a state of being aligned in a certain horizontal direction and piped.

Next, prevention of removal of the support 1 configured as described above from the suspension bolt 61 will be described with reference to FIG. Here, FIG. 6 is an explanatory view schematically showing the interval between the side end portions of the pair of clamping pieces.
As shown in FIG. 6 (a), the support 1 of the present embodiment has a pair of sandwiching pieces 12, in a state where the suspension bolt 61 is sandwiched between the pair of sandwiching pieces 12 and 13 and fixed to the suspension bolt 61. 13 has an overlapping portion in the circumferential direction of the suspension bolt 61 in a state where the side end portions are separated from each other by the interval S, and the sandwiching piece 12 and the sandwiching piece 13 are the same except for the position of the through hole 17 and the like. Therefore, the engagement length in the circumferential direction with the outer peripheral surface of the suspension bolt 61 on the lower side 12a of the sandwiching piece 12 and the upper side 13a of the sandwiching piece 13 is a side view at a location where the pair of sandwiching pieces 12 and 13 face each other. In both cases, the length is L1.

  On the other hand, in the case of the sandwiching pieces such as the pair of clamp members 85 and 86 described in Patent Document 1, as shown in FIG. 6B, the opposing sides of the pair of sandwiching pieces 12 and 13 The end portions are linearly formed along the axial direction of the suspension bolt 61, the side end portions are separated from each other by a distance S, and the engagement length with the outer peripheral surface of the suspension bolt 61 is L2 in a side view. It is length.

  Therefore, when both are compared, the side end portions are spaced apart at the same interval S, but the engagement length with the outer peripheral surface of the suspension bolt 61 is, as is apparent from FIG. L1> L2. This is the same regardless of the distance between the side end portions of the pair of sandwiching pieces 12 and 13, for example, even when the side end portions are in contact with each other and the interval is zero. For this reason, a load that causes the support member 21 to rotate downward about the portion that holds the suspension bolt 61 is applied, or a large force that pulls the support tool 1 in a direction perpendicular to the axis of the suspension bolt 61 is applied. The support member 1 according to the present embodiment clearly has a larger force that prevents the suspension bolt 61 from being pulled out from the suspension bolt 61, like the pair of clamp members 85 and 86 described in the conventional Patent Document 1. In the case of a simple clamping piece, the suspension bolt 61 may be removed, whereas in the case of the support tool 1 of the present embodiment, such a problem does not occur.

Next, workability when the support 1 of the present embodiment is attached to and detached from the suspension bolt 61 will be described with reference to FIG. FIG. 7 is an explanatory view schematically showing the interval between the side end portions of a pair of sandwiching pieces.
First, the case where the support tool 1 is attached and fixed to the suspension bolt 61 will be described. Here, it is assumed that the support 1 is preliminarily assembled with a fixing member 11 and a support member 21 via a connector 31. In this state, the connecting bolt 32 or the hexagon nut 33 is loosened, and the pair of clamping pieces 12 and 13 are temporarily moved from the position indicated by the solid line in FIG. If the interval between the side end portions 15a is expanded in the direction orthogonal to the axis of the suspension bolt 61, that is, the arrow direction in FIG. 7A, the lower end corner portion 14b of the holding piece 12 and the upper end corner portion 15b of the holding piece 13 Is moved from P1 to P2, and the suspension bolt 61 is moved in the space between the pair of sandwiching pieces 12 and 13 only when the distance between the side end portion 14a and the side end portion 15a is at least larger than the outer diameter of the suspension bolt 61. It is possible to pass through and accommodate in the pair of sandwiching pieces 12 and 13. For this reason, it is necessary to loosen the connecting tool 31 and move both the clamping pieces to the left and right outwards by at least the length of L1, but since P1 extends to a position beyond the center line of the suspension bolt 61, At the time of the movement, the connector 31 has to be screwed by a considerable distance by a considerable number of turns.

  However, in the support tool 1 of the present embodiment, the opposing side end portions of the respective clamping pieces are inclined linearly, so that the fastening of the connecting tool 31 is loosened by rotating the support tool 1 by a predetermined angle. The number of turns and the screwing distance can be greatly reduced. That is, as shown in FIG. 7B, when the support 1 is rotated by a predetermined angle about the rotation center O to be parallel to the axis of the suspension bolt 61, the side end portion 14a of the clamping piece 12 is obtained. Both the lower end corner 14b and the upper end corner 15b of the side end 15a of the sandwiching piece 13 retreat from the position P1 in FIG. 7 (a) to the position P3 in FIG. 7 (b), and the inclination in FIG. 7 (b). In terms of angle, both retreat to the opposite side of the center line of the suspension bolt 61. As a result, in order to allow the suspension bolt 61 to pass through the space between the pair of sandwiching pieces 12, 13, the sandwiching piece 12 and the sandwiching piece 13 have a length L3 from P3 to P4 in the direction of the arrow in FIG. Just move it. Here, as is apparent from FIG. 7, L3 <L1. Therefore, prior to attaching the preliminarily assembled support tool 1 to the suspension bolt 61, the connecting tool 31 is loosened to extend the distance between the side end portion 14a of the holding piece 12 and the side end portion 15a of the holding piece 13. The amount will be greatly reduced.

  Incidentally, in the case of the conventional clamping device described in Patent Document 2, in order to hold the pipe between the pair of clamp pieces 92 and 93, each clamp piece has a length of at least L4 as shown in FIG. The length must be widened and the connector 31 must be loosened over a considerable length.

Thus, if the space | interval of the side edge part of a pair of clamping pieces 12 and 13 is expanded, the suspension bolt 61 will be allowed to pass through in the expanded space, and it will accommodate in the inside of a pair of clamping pieces 12 and 13. Next, the support tool 1 is rotated by a predetermined angle in the reverse direction to return to the original position, that is, the fixed position, and then the connection tool 31 is tightened to fix the support tool 1. Here, in the tightening, since the amount of expansion of each side end portion of the pair of sandwiching pieces 12 and 13 when passing the suspension bolt 61 is small, naturally, the number of times of tightening by turning the connector 31 is Less and the screwing distance may be short.
Therefore, when the connecting tool 31 is loosened and the suspension bolt 61 is passed through the space between the side ends of the pair of sandwiching pieces 12 and 13, and when the connecting tool 31 is tightened after passing, the rotation of the connecting tool 31 is performed. The number and the screwing distance can be reduced, and the mounting operation can be performed promptly.

  Although the case where the support tool 1 is attached to the suspension bolt 61 has been described above, the same applies to the case where the support tool 1 fixed to the suspension bolt 61 is removed. That is, as shown in FIG. 7 (b), the support 1 is rotated by a predetermined angle with respect to the suspension bolt 61 and tilted so that the side ends of the pair of sandwiching pieces 12, 13 are parallel to the axis of the suspension bolt 61. In this state, the pair of sandwiching pieces 12 and 13 can be removed by merely expanding the pair of sandwiching pieces 12 and 13 in the direction of the arrow in FIG. Accordingly, the amount of loosening the connecting bolt 31 may be reduced accordingly, so that the removal work can be performed quickly. Note that when the support tool 1 is rotated and tilted, it cannot be immediately rotated, so that the connecting bolt 31 is loosened while the distance between the side ends of the pair of holding pieces 12 and 13 is increased. It will be rotated.

  By the way, as for the support tool 1 of the said embodiment, although the pair of clamping pieces 12 and 13 are each provided with the one through-hole 17 of a connection bolt, it has shown what expands right and left in the same height. As shown in FIG. 8, it is good also as what formed the through-hole 17 of the at least one clamping piece in the elongate hole 17a elongated in the up-down direction. That is, as shown in FIG. 9A, the support 1 may be configured such that the pair of sandwiching pieces 12 and 13 are relatively spaced apart in the vertical direction in addition to being spaced apart from each other in the horizontal direction. In FIG. 8, one of the holding pieces 12 is formed with a long hole 17 a that is long in the vertical direction, and when the support tool 1 is attached to and removed from the suspension bolt 61, the connector 31 is loosened. At the same time, the shaft portion of the connecting bolt 32 is moved in the long hole 17 a of the sandwiching piece 12, and the sandwiching piece 12 is moved downward relative to the sandwiching piece 13. In this case, of course, even if the connecting tool 31 is loosened and the holding piece 12 is moved downward, the side ends of the pair of holding pieces 12 and 13 are immediately parallel to the axial direction of the suspension bolt 61. Since the support tool 1 cannot be rotated and tilted, the support tool 1 is rotated while the connection tool 31 is loosened.

  Thus, when the holding piece 13 is moved vertically downward, the distance between the side end portions of the pair of holding pieces 12 and 13 is a length L5 corresponding to the relative movement downward as shown in FIG. 9 (a). The distance between the pair of sandwiching pieces 12 and 13 is initially S but is expanded to (S + S1). Further, as shown in FIG. 9 (b), the spread amount of the sandwiching piece 12 is sufficient by a length L6 that is smaller than L3 in FIG. 7 (b). Therefore, the connecting tool 31 can further reduce the number of rotations that are further loosened by the amount of increase in the interval as described above, thereby reducing the amount of screwing. In addition, also in the clamping piece 13, if the through-hole 17 of a connection bolt is formed in a long hole, the screwing amount of the connection tool 31 required when the support tool 1 is attached or detached can be further reduced. These are the effects derived from the fact that the side end portions of the pair of sandwiching pieces 12 and 13 are linearly inclined with respect to the axial direction of the suspension bolt 61.

Next, the operation of the support tool of this embodiment will be described.
In the support 1, the side end portions of the pair of sandwiching pieces 12 and 13 are inclined linearly with respect to the axial direction of the suspension bolt 61, so the engagement length in the circumferential direction with the suspension bolt 61 is increased. can do.
For this reason, a great load is applied to the support member 21 or a strong external force is applied to move the support tool 1 in a direction perpendicular to the axis of the suspension bolt 61 to pull the support tool 1 out of the suspension bolt 61. It is possible to prevent the support 1 from being pulled out of the suspension bolt 61 when force is applied.

  In addition, since the side end portions of the pair of sandwiching pieces 12 and 13 are inclined linearly with respect to the axial direction of the suspension bolt 61, when the support tool 1 is attached to and detached from the suspension bolt 61, the pair of sandwiching pieces 12 and 13 is sandwiched. Even if the amount of screwing to loosen the coupling tool 31 is small by tilting the support tool 1 by a predetermined angle so that the side ends of the pieces 12 and 13 are parallel to the axis of the suspension bolt 61, the suspension bolt 1 61 can be passed in the space between the side ends of the pair of sandwiching pieces 12 and 13. As a result, the time required for fixing and removing the support tool 1 can be shortened, and the work can be easily performed. Further, by making the through-hole 17 of the connecting bolt 32 in at least one clamping piece a long hole in the vertical direction, the clamping pieces can be separated from each other in the vertical direction, thereby increasing the interval between the clamping pieces. . As a result, the amount of screwing of the connector 31 can be further reduced by the amount of the increase in the interval.

  Next, in the support 1 of the above embodiment, the support member 21 shown in FIG. 4 and the like is connected to the fixing member 11 including the pair of sandwiching pieces 12 and 13. Various support members can be connected according to the body and the support form. FIG. 10 shows another support member 41. In FIG. 10, the support member 41 is formed in a flat rectangular box-like body whose one surface is opened by a synthetic resin material, and a large number of small holes 43 into which screws can be screwed at predetermined intervals on the surface side of the bottom wall 42. Various installation bodies such as wiring devices, breakers, switch devices, lighting devices, watt-hour meters boxes, instrument boxes, etc. It can be installed freely at any position. In the support member 41, an insertion hole 44 through which a cable is inserted is provided at the center of the bottom wall 42. The side wall 45 of the support member 41 is provided with a line knockout 46 used for drawing in a VE pipe or the like.

  At two locations on the inner surface side of the bottom wall 42 of the support member 41, fixing member mounting portions 47 formed of a substantially U-shaped standing frame are provided. The central portion of the fixing member mounting portion 47 is a through space, and the connecting bolt 32 can be inserted therethrough. The pair of clamping pieces 12 and 13 of the fixing member 11 are arranged so as to be sandwiched from both sides of the fixing member mounting portion 47, and the connecting bolt 32 is connected to the through holes 17 of the pair of clamping pieces 12 and 13 and the fixing member mounting portion 47. After being inserted through the through space, the fixing member 11 and the support member 41 are connected by the hexagon nut 33 being screwed and tightened.

  Now, assuming that the fixing member 11 and the supporting member 41 are temporarily assembled to the support tool 1 via the connector 31, in order to fix the support tool 1 to the suspension bolt 61, the support tool shown in FIG. 1, the fixing member 11 and the support member 41 are connected to each other and the connecting tool 31 that is temporarily fixed is loosened to widen the distance between the side end portions of the pair of sandwiching pieces 12, 13. When the outer diameter of 61 is larger, the suspension bolt 61 is passed from the side in the space between the pair of sandwiching pieces 12 and 13 and accommodated in the pair of sandwiching pieces 12 and 13, and then the connector 31 is firmly tightened. . Thereby, the support tool 1 is fixed to a vertically long state or a horizontally long state with respect to the suspension bolt 61 as shown in FIG. Thereafter, a screw is screwed into an arbitrary small hole 43 of the support member 41 so that, for example, a watt-hour meter box 74 as an arrangement body is supported by the support member 41 as shown by a two-dot chain line in FIG. Let

  In the support tool 1 to which the support member 41 is connected, the amount of loosening the connection tool 31 can be reduced when attached to the suspension bolt 61 in the same manner as the support tool 1 shown in FIG. Since the amount of screwing required for tightening the connecting bolt can be reduced even during re-tightening, the support 1 can be easily fixed to the suspension bolt 61 in a short time. Similarly, when the support 1 is removed from the suspension bolt 61, the amount of loosening the connecting bolt can be reduced, and the removal can be easily performed in a short time.

  By the way, although a pair of clamping pieces 12 and 13 of the support 1 of each said embodiment are formed symmetrically except for one end part etc., as shown in Drawing 12, for example, the peripheral direction of clamping piece 13 The engagement length may be longer than the sandwiching piece 12. The pair of sandwiching pieces 12 and 13 are formed by bending one end of a metal plate material such as a substantially rectangular plate-shaped steel plate into a circular arc shape by pressing, but are not limited to this shape.

  Further, as shown in FIG. 13, the support tool of each of the above embodiments is provided at least one of the lower end corner portion 14 b of the lower side 12 a of the holding piece 12 and the upper end corner portion 15 b of the upper side 13 a of the holding piece 13. A locking protrusion 13b or the like that slightly protrudes and fits between the threads of the suspension bolt 61 may be provided. In this case, it is possible to reliably prevent the support 1 from shifting in the axial direction with respect to the suspension bolt 61.

  Further, the pair of holding pieces 12 and 13 of the support 1 of each of the above embodiments are formed so that the side end portions are parallel to each other in a state where the suspension bolt 61 is held, but the present invention is not limited to this. In addition, the support 1 of the present invention can also be applied to those in which the sandwiching pieces are not parallel to each other.

And although the said support tool 1 is connected with the pair of clamping pieces 12 and 13 and the support member via the connection tool 31, it is good also as what integrated one of the clamping pieces and the support member. .
Each support member may be connected to only one of the sandwiching pieces via the connector 31.

  In addition, in each of the above embodiments, the suspension bolt 61 is applied as a rod-shaped body. However, the rod-shaped body is not limited to this, and a rod-shaped body having a circular cross section without a threaded portion or an elliptical cross section. The present invention can be similarly applied to a rod-shaped body, various elongated cylindrical bodies, a rod-shaped body having a hexagonal cross section, an octagonal shape, and the like.

  In addition, the connecting bolt 32 is connected to the pair of holding pieces 12 and 13 and the support member by the hexagon nut 33, but the peripheral edge of the through hole 17 of one or both holding pieces is cut and raised. A female screw into which the male screw of the connecting bolt 32 is screwed may be screwed into the raising portion. In this case, the hexagon nut 33 can be dispensed with.
