Description

  The present invention relates to a long material support for supporting a long material such as a cable, a conduit tube, or a sheath tube on a round bar material such as a suspension bolt or a deformed reinforcing bar of a building.

  Conventionally, a long bar material such as a cable or a conduit is supported on a round bar material such as a suspension bolt of a building, and the long material is laid along the laying path. The long material can be supported by a round bar through a support, and for example, a support described in JP-A-2003-348739 is used.

  FIG. 11 shows a support tool described in Japanese Patent Laid-Open No. 2003-348739. In FIG. 11, the support tool 61 is configured by connecting a mounting part 62 and a support part 63 which are separate members. A pair of clamping pieces 65 for supporting the suspension bolt 41 as a round bar so that the attachment portion 62 of the support 61 is curvedly formed on the base portion 64 and held from the opposite side of the attachment portion 62 of the suspension bolt 41 of FIG. They are arranged apart from each other in the axial direction. On the other hand, the support portion 63 of the support 61 is connected such that the connecting shaft 67 is inserted into the connection hole 66 of the attachment portion 62 so that the mounting direction with respect to the attachment portion 62 can be changed. A support piece 68 that supports, for example, the cable 51 as a material is provided.

  The support 61 configured in this manner is parallel to the surface of the base 64 after the suspension bolt 41 is inserted between the pair of sandwiching pieces 65 perpendicular to the parallel arrangement direction of the pair of sandwiching pieces 65. Then, the suspension bolt is rotated 90 degrees in the vertical direction, and the suspension bolt 41 is attached to an appropriate position of the suspension bolt 41 so as to be fitted into the holding piece 65. After being attached in this way, as shown in FIG. 12, the support portion 62 has the curved portion of the holding piece 65 in contact with the outer peripheral surface of the suspension bolt 41, so that the suspension bolt 41 is interposed between the support portion 62 and the base portion 64. Thus, the suspension bolt 41 is stably held by the suspension bolt 41.

JP 2003-348739 A

  By the way, the suspension bolt 41 generally has a diameter of W3 / 8, that is, M10, but in recent years, the frequency of use of a diameter of W1 / 2, that is, M12 has increased.

  However, the conventional support tool disclosed in JP-A-2003-348739 and the like is provided with a dedicated support for each suspension bolt 41 having a different diameter, and is selectively used according to the size of the suspension bolt 41. For this reason, the cost is high, and parts management is also complicated.

  Here, it is also conceivable that the space between the pair of holding pieces 65 of the support tool 61 and the accommodation space are formed corresponding to the diameter of the large-diameter suspension bolt 41 so that the large and small suspension bolts 41 can be shared. However, when the support tool 61 formed corresponding to the large-diameter suspension bolt 41 is attached to the small-diameter suspension bolt 41, there is a gap between the inner surface of the holding piece 65 of the support tool 61 and the outer peripheral surface of the suspension bolt 41. As shown in FIG. 13, when the external force is applied from the lateral direction, lateral displacement occurs, and in some cases, the clamping piece 65 is detached from the suspension bolt 41 and dropped. There is a risk that. Therefore, the support state is very unstable, and along with this, a long material such as a cable or a tube supported by the support portion 63 of the support tool 61 may rattle and fall.

  Conversely, when the support 61 formed corresponding to the small-diameter suspension bolt 41 is attached to the large-diameter suspension bolt 41, the suspension bolt 41 cannot be accommodated in the clamping piece 65. It will be in the state inclined with respect to the said suspension bolt 41, and cannot be supported in a predetermined position.

  Accordingly, an object of the present invention is to provide a long material support that can be shared by a single type of round bar material having different diameters and can be selectively attached.

  The long material support according to claim 1, which supports a long material that can be attached to at least two types of round bars having different diameters, and is attached to the round bar. Part and the support part which supports the said elongate material. The attachment portion is spaced apart from the base portion in the axial direction of the round bar in the attached state, and is juxtaposed to the base, and is bent so as to hold the round bar from the opposite side. It has a pair of clamping pieces, and an insertion part formed between the pair of clamping pieces and into which the round bar is inserted perpendicularly to the juxtaposed direction.

  The pair of sandwiching pieces can be expanded outwardly so as to accommodate a large-diameter round bar in the interior, and after the accommodation, the pair of sandwiching pieces can be connected to the base by an elastic restoring force in a direction of reducing the diameter inward. It is formed so that it may be pinched. Further, the pair of sandwiching pieces can be expanded outwardly so as to accommodate a small-diameter round bar material inside, and the gap formed between the small-diameter round bar material and the sandwiching piece after the accommodation. In order to prevent the round bar from moving, a fitting recess in which the outer peripheral part of the small-diameter round bar is fitted is attached between at least one of the clamping pieces in the base and the inner side of the clamping piece. It is formed along the axial direction of the round bar in the state, and in the fitted state, it is formed so as to be sandwiched between the base by an elastic restoring force in the direction of reducing the diameter inward.

  In the following description, the round bar is a bar having a circular cross section such as a suspension bolt or deformed reinforcing bar, and is mainly intended for a screw whose outer peripheral surface is threaded, such as a suspension bolt. Also included are those in which the screw is partially formed and those not formed to the full length. The long material is a wire material such as a cable, or a tube material such as a conduit tube, and is laid along the laying path supported by the round bar material.

  The support includes an attachment portion attached to the round bar and a support portion that supports the elongated member, and the attachment portion and the support portion are formed integrally or separately. It is formed by connecting them as a body. When the attachment part and the support part are configured separately, it is possible to replace only the support part and apply to various long materials. It is also possible to change the support direction of the long material with respect to the round bar by changing the mounting direction and position of the support portion with respect to the attachment portion.

  The attachment portion has a base, a pair of clamping pieces that are clamped so as to hold the round bar from the opposite side, and an insertion part into which the round bar is inserted before clamping. The pair of sandwiching pieces are arranged in parallel to the base portion apart from each other in the axial direction of the round bar in a state of being attached to the round bar, that is, provided at an oblique position, A synthetic resin or the like can be used to stand integrally with the base. The pair of sandwiching pieces rise from the base, and are bent in a direction approaching each other in the middle, and sandwich the round bar with the base so as to hold it from the opposite side.

  An insertion portion of the round bar is formed between a pair of holding pieces that are spaced apart in the axial direction of the round bar, and the round bar is, for example, at the start of attachment of the pair of holding pieces. It is inserted perpendicularly to the juxtaposed direction, and can then be accommodated in the holding piece by turning the support tool by 90 degrees.

  The pair of sandwiching pieces can be expanded in diameter so as to accommodate a large-diameter round bar member, and are formed so as to be sandwiched between the base portion by elastic restoring force after being accommodated. As a result, the support is held at a fixed position with respect to the large-diameter round bar, and is prevented from being laterally displaced by receiving a lateral external force. The sandwiching piece is erected on the base, and then curved toward the inside of the support, and the curved portion has a topmost portion that is the portion farthest upward from the base in the curved portion. Furthermore, it extends to a position beyond that to prevent separation from the clamping piece.

  Further, the pair of sandwiching pieces is formed with a fitting recess in which the outer peripheral portion of the small-diameter round bar is fitted between the sandwiching pieces in the base portion, on the inner surface side of the sandwiching piece, or both. In the fitted state, it is formed so as to be held between the base portion by an elastic restoring force. Thus, the support is held at a fixed position along the axis with respect to the small-diameter round bar, and is prevented from being laterally displaced by an external force.

  Here, the clamping piece is formed in a curved shape and has a large shape rigidity. Further, the plate thickness is formed to a certain size or more. Therefore, since it has a required rigidity and a large elastic restoring force in the direction of reducing the diameter inward, the round bar is firmly held between the base and stably held by the round bar. When attaching to the round bar, the pair of sandwiching pieces bend at the upright part from the base, and the opening between the tip of the curved part and the base widens and expands outward. A round bar can be inserted into the holding piece and accommodated.

  According to a second aspect of the present invention, there is provided the elongated material support, wherein the pair of sandwiching pieces are formed of an upright portion erected on the base portion and an arc portion that abuts along the outer peripheral surface of the large-diameter round bar material, The interval between the upright portions is the same as the diameter of the large-diameter round bar. Thereby, while being able to attach a support tool to a large diameter round bar material, it is hold | maintained to the said round bar material more stably.

  The long material support of claim 3 is formed so that the fitting recess comes into contact with the outer peripheral surface of the small-diameter round bar. Thereby, a support tool is stably hold | maintained by the fixed position along the axis | shaft with respect to the said small diameter round bar.

  According to a fourth aspect of the present invention, the attachment member and the support portion are separately formed, and the support portion is detachably attached to the attachment portion.

  According to a fifth aspect of the present invention, there is provided the support member for a long material in which the support portion is attached to the attachment portion so that the attachment direction can be changed. The mounting direction can be changed by shifting the connecting position.

  The long material support according to claim 1 is stably held at a fixed position with respect to any of at least two types of round bars having different diameters, and accordingly, the long material is supported by the support. The material is stable and is supported stably. For this reason, it can be selectively attached to a round bar having a different diameter. As a result, the number of parts can be reduced, the cost can be reduced, and parts management can be facilitated.

  The long material support according to claim 2 or 3 is more stably held against any of at least two types of round bars having different diameters. Thereby, like Claim 1, it can attach to a round bar with a different diameter freely.

  Since the support part of the long material of Claim 4 is attached to the attachment part so that attachment or detachment is possible, only this support part can be replaced | exchanged according to the kind of long material. Thereby, the attachment portion can be used in common, and the component cost can be reduced.

  Since the support part of the long material of Claim 5 is attached so that attachment direction can be changed with respect to an attachment part, the support direction of the long material supported by a support part can be changed arbitrarily. .

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 6. Here, FIG. 1 is a perspective view showing a support tool according to an embodiment of the present invention, FIG. 2 is a partially broken side view of the support tool, FIG. 3 is an exploded perspective view of the support tool, and FIG. The attachment part which comprises a tool is shown. In addition, in this embodiment, the support tool which supports a cable to the suspending bolt hanging from the ceiling is shown.

  1 to 4, the support 1 is attached to a suspension bolt 41 suspended from a double ceiling of a building to support the cable 51, and the attachment portion 2 attached to the suspension bolt 41 and And a support portion 21 that supports the cable 51. The attachment part 2 and the support part 21 are formed as separate bodies, are detachably assembled at each central part, and are each formed of a synthetic resin. The suspension bolt 41 corresponds to the round bar of the claims, and generally, a small diameter W3 / 4 and a large diameter W1 / 2 are used, and a male screw is formed over the entire length. ing. The cable 51 corresponds to the long material of the claims, and is supported in a horizontal direction orthogonal to the axial direction of the suspension bolt 41 in FIG.

  First, the attachment portion 2 has a predetermined distance in the axial direction of the suspension bolt 41 in the attached state, that is, in the vertical direction in FIG. 1, when the pair of sandwiching pieces 4 are sandwiched so as to hold the suspension bolt 41 on the rectangular plate-shaped base portion 3. They are spaced apart from each other. And the insertion part by which the said suspending bolt 41 is inserted in the state orthogonal to the parallel arrangement direction of the said clamping piece 4, or an oblique state between the pair of clamping pieces 4, ie, a horizontal direction or an oblique direction, if it shows in FIG. 9 is formed. In other words, the pair of sandwiching pieces 4 are spaced apart at least at an interval larger than the outer diameter of the suspension bolt 41 in the vertical direction in FIG. 4C, and the insertion portion 9 formed therebetween is in a state in which the suspension bolt 41 is attached. It is formed in such a size that it can be inserted from a direction perpendicular to the axis or from an oblique direction.

  The pair of sandwiching pieces 4 rises at a position near the side portion of the base portion 3 and then bend in an arc shape toward the center, and the tips thereof are most upward from the base portion 3 at least in the curved portion in the attached state. It extends to a position beyond the topmost part 6a which is a distant part. An opening 7 is formed between the distal end of the sandwiching piece 4 and the base 3 so that the suspension bolt 41 is inserted along the surface of the base 3 as described later. More specifically, the sandwiching piece 4 is roughly upright and rises substantially vertically with a length corresponding to the radius of the suspension bolt 41, and a large-diameter suspension bolt 41 curved from the upper end of the elevation 5. And an arcuate portion 6 that abuts along the outer peripheral surface. The distance between the upright portions 5 of the pair of sandwiching pieces 4 is formed to be substantially the same as the diameter of the large-diameter suspension bolt 41. And the said clamping piece 4 is formed in the whole width | variety, the cross-sectional shape is constant, and plate | board thickness is about 2 mm. However, it goes without saying that the thickness of the sandwiching piece 4 is not limited to about 2 mm.

  The arc portion 6 of the sandwiching piece 4 formed in this way has an arc shape having a large shape rigidity over the entire width, and since the plate thickness is also large, the rigidity is large overall and a constant shape is maintained. It is difficult to deform. Therefore, since the elastic restoring force for reducing the diameter inward after the suspension bolt 41 is accommodated after the diameter is expanded outward at the time of attachment is large, the suspension bolt 41 is firmly held between the base portion 3. . In addition, when attaching to the suspension bolt 41, the deflection 7 occurs at the rising portion 5 from the base portion 3, the opening 7 between the distal end of the curved portion and the base portion 3 expands, and the suspension bolt 41 is placed in the holding piece 4. Can be inserted and housed.

  Further, a claw portion 8 is provided at a substantially central portion of the end portion on the insertion portion 9 side of the circular arc portion 6 so as to protrude to the inner side and engage with a screw concave portion of the hanging bolt 41 after the attachment.

  On the other hand, an arcuate fitting recess 10 that abuts along the outer peripheral surface of the small-diameter suspension bolt 41 is formed substantially in the center of the base portion 3 in the axial direction of the suspension bolt 41 in the attached state. The fitting recess 10 is formed in such a size and depth that at least the outer peripheral portion of the small-diameter suspension bolt 41 is fitted and cannot be easily detached and laterally displaced by an external force or the like. If the fitting recess 10 is too deep, the outer peripheral surface of the suspension bolt 41 does not come into contact with the arc portion 6 of the sandwiching piece 4, and the suspension bolt 41 cannot be sandwiched. Therefore, it is necessary to set the optimal size in consideration of both. As a result, the small-diameter suspension bolt 41 has a part of its outer peripheral portion in contact with the inner wall surface of the fitting recess 10, and the fitting force is applied by the elastic restoring force in the direction of reducing the diameter inward after the suspension bolt 41 is received. Since the inner wall surface of the recess 10 and the clamping piece 4 are firmly clamped, the support 1 is stably held along the axis of the suspension bolt 41.

  Further, a connecting hole 11 for connecting to the support portion 21 is provided in the central portion of the base portion 3. An annular step portion 12 that extends to the entire inner periphery and protrudes into the connection hole 11 is integrally provided at a substantially intermediate position in the depth direction of the connection hole 11. Further, as shown in FIG. 4B, engaging grooves 13 that radially extend around the rotation center C are formed at equal intervals in the circumferential direction on the back surface side of the base 3. In this engagement groove 13, a protrusion 26 of the support portion 21 to be described later is engaged. In the present embodiment, eight engagement grooves 13 are formed at equal intervals in the circumferential direction with a central angle of 45 degrees.

  Next, the support portion 21 connected to the attachment portion 2 has a connection shaft 23 having a slit 24 in the center portion on one surface side of the support portion 21 facing the connection hole 11 of the base portion 3 of the attachment portion 2. Are provided integrally. On the opposite surface side of the base portion 22 of the support portion 21, a support piece 27 is integrally arranged in a direction perpendicular to the plane of the base portion 22. The connecting shaft 23 is formed with a locking claw 25 at the tip portion to be locked to the annular stepped portion 12 of the attachment portion 2 to prevent it from coming off, and the slits 24 of the connecting shaft 23 are formed on the surface of the base portion 22. A protrusion 26 is provided at the bottom portion so as to reach the entire width of the base portion 22 and fit into the engagement groove 13 of the base portion 3 of the attachment portion 2. The protrusion 26 is elastically detached from the engagement groove 13 by forcibly rotating about the rotation center C while pulling the support portion 21 to the opposite side of the attachment portion 2, It can be fitted in the engaging groove 13. Thereby, the support portion 21 can change the mounting direction with respect to the attachment portion 2 while shifting the central angle in the circumferential direction about the rotation center C by 45 degrees.

  On the other hand, the support pieces 27 of the support portion 21 are arranged side by side on the base portion 22 at equal intervals. In the present embodiment, four support pieces 27 are formed. A cable 51 is placed and supported in the support space 28 formed between the support pieces 27. In FIG. 1, the support portion 21 supports the cable 51 so as to be laid in a horizontal direction orthogonal to the suspension bolt 41. However, as described above, the mounting direction of the attachment portion 2 is changed. By doing so, the supporting direction of the cable 51 can be changed to a direction inclined by 45 degrees from the horizontal direction and further to a vertical direction.

Next, a method for attaching the support tool of the present embodiment configured as described above to the suspension bolt 41 will be described with reference to FIG.
First, as shown in FIG. 5A, the support 1 is brought close to the suspension bolt 41 from the side direction orthogonal to the axis thereof, and the suspension bolt 41 is inserted into the insertion portion 9. Next, the support 1 is rotated counterclockwise along the surface of the base 3, and the corners of the arc 6 of the clamping piece 4 are the outer peripheral surfaces of the suspension bolts 41 as shown in FIG. Then, the suspension bolt 41 is forcibly rotated in the same direction, and the suspension bolt 41 is accommodated inside the holding piece 4 while elastically expanding the opening 7 of the holding piece 4. At this time, since the arc portion 6 has rigidity and is not easily deformed, the sandwiching piece 4 is bent mainly at the upright portion 5, and the opening 7 is expanded and inserted. When the suspension bolt 41 is accommodated in the clamping piece 4, it is held at the position shown in FIG.

  Here, when attached to the large-diameter suspension bolt 41, as shown in FIG. 6A, the entire arc portion 6 abuts on the outer peripheral surface of the suspension bolt 41, and the fitting recess 10 has both opening edges. Comes into contact with the outer peripheral surface of the suspension bolt 41. On the other hand, when attached to the small-diameter suspension bolt 41, the axial direction of the suspension bolt 41 with the entire inner surface of the fitting recess 10 in contact with the outer peripheral surface of the suspension bolt 41 as shown in FIG. Mate along.

Next, the operation of the support tool of the present embodiment will be described.
In the support 1 of this embodiment, the insertion portion 9 into which the suspension bolt 41 is inserted is formed between the sandwiching pieces 4, and the sandwiching pieces 4 on both sides thereof are formed in an arc shape so as to hold the suspension bolt 41. From the direction perpendicular to the axis of the suspension bolt 41, and when the suspension bolt 41 is inserted into the insertion portion 9, the suspension bolt 41 is forcedly rotated along the surface of the base portion 3 to hold the suspension bolt 41 in the clamping piece 4. Can be housed and attached. Therefore, the support 1 can be easily attached to the suspension bolt 41 from a direction orthogonal to the axis of the suspension bolt 41 at an arbitrary position and height of the suspension bolt 41.

  In particular, the pair of clamping pieces 4 of the attachment portion 2 can accommodate a large-diameter suspension bolt 41 therein, and the arc portion 6 abuts along the outer peripheral surface of the large-diameter suspension bolt 41. A fitting recess 10 that is formed in an arc shape and abuts along the outer peripheral surface of the small-diameter suspension bolt 41 is formed in the base portion 3 of the attachment portion 2 in the axial direction of the suspension bolt 41 in the attachment state. Therefore, it is possible to selectively attach to two types of suspension bolts 41 having different types of large and small diameters.

  That is, first, for both large and small suspension bolts 41, the sandwiching piece 4 can be inserted into the sandwiching piece 4 with the raised portion 5 being mainly bent and the opening 7 being expanded. Further, the sandwiching piece 4 is formed such that the interval between the raised portions 5 is substantially the same as the diameter of the large-diameter suspension bolt 41 and can accommodate the large-diameter suspension bolt 41 therein. Therefore, the support 1 can be attached to both the large and small suspension bolts 41.

  Next, the large-diameter suspension bolt 41 is formed in an arc shape in which the arc portion 6 reaches the entire width of the sandwiching piece 4 and abuts along the outer peripheral surface of the large-diameter suspension bolt 41 as described above. After the attachment, as shown in FIG. 6 (a), the inner surface of the arc portion 6 is entirely brought into contact with the outer peripheral surface of the suspension bolt 41 by the elastic restoring force in the direction of reducing the diameter inward, and the base 3 Press strongly toward the side. In addition, the arc portion 6 is highly rigid in shape and thick, and is not easily deformed. As a result, the suspension bolt 41 is strongly clamped between the base 3 and the clamping piece 4, so that the support 1 is not laterally displaced as shown in FIG. It is always held stably in a fixed posture without moving away. As a result, the cable 51 supported by the support 1 is also stably supported in a certain direction, and a good laying state can be maintained.

  Next, with respect to the small-diameter suspension bolt 41, the base 3 of the attachment portion 2 has a fitting recess 10 that abuts along the outer peripheral surface of the small-diameter suspension bolt 41. It is formed in the axial direction. After the attachment, as shown in FIG. 6 (b), the inner surface of the fitting recess 10 is entirely in contact with the outer peripheral surface of the suspension bolt 41. At this time, the circular arc portion 6 is brought into contact with the abutting portion 4a of one clamping piece 4 and the other clamping piece 4 in FIG. 6B by the elastic restoring force in the direction in which the outer peripheral surface of the suspension bolt 41 is reduced inward. The suspension bolt 41 is strongly pressed against the inner surface of the fitting recess 10 in order to press strongly in the radial direction at the contact portion 4b. For this reason, since the suspension bolt 41 is strongly clamped by the clamping piece 4 and the fitting recess 10 formed in the base portion 3, it is prevented from being detached from the fitting recess 10 in the lateral direction and is always in the fitting recess 10. Maintained. As a result, as shown in FIG. 6 (b), even if there is a gap between the inner surface of the clamping piece 4 and the outer peripheral surface of the suspension bolt 41, there is no rattling, and in the case of a large-diameter suspension bolt 41. In the same manner as described above, when an external force is applied, a lateral shift does not occur as shown in FIG. As a result, the cable 51 supported by the support 1 is also stably supported in a certain direction, and a good laying state can be maintained.

  Therefore, according to the support tool 1 of the present embodiment, both the large-diameter suspension bolt 41 and the small-diameter suspension bolt 41 are rattled, laterally displaced by an external force from the side, and further from the opening 7. Without being detached, it is stably held at a fixed position. Therefore, as described above, the suspension bolt 41 can be shared by two types of large and small suspension bolts 41 having different diameters.

  In addition, it is possible that the external force to the said support tool 1 applies directly, and acts via elongate materials, such as a tubular body supported by the support part 21.

  By the way, although the fitting recessed part 10 of the said embodiment is formed in the base 3, it can also be formed in the inner surface side of the clamping piece 4. FIG. FIG. 7 shows the support 1 in which the fitting recess 10 is formed on the inner surface side of the holding piece 4. FIG. 7A shows a state before the support 1 is attached to the suspension bolt 41. FIG. Fig. 7 (c) shows a case where it is attached to a large-diameter suspension bolt 41, and Fig. 7 (c) shows a case where it is attached to a small-diameter suspension bolt 41.

  In FIG. 7A, the fitting recess 10 formed in the range A on the inner surface side of the holding piece 4 has an arc of the fitting recess 10 so as to abut along the outer peripheral surface of the small-diameter suspension bolt 41. It is formed to have the same curvature as the outer peripheral surface of the small-diameter suspension bolt 41. Further, in the sandwiching piece 4, the arc portion 6 on the distal end side with respect to the fitting recess 10 is formed so as to contact along the outer peripheral surface having a large diameter. In FIG. 7, the description of the range “a” is omitted for the pinching piece 4 on the back side.

  Also in this support tool 1, similarly to the support tool 1 in which the fitting recess 10 is formed in the base portion 3 described above, the support tool 1 is held in a stable state with respect to both the large and small suspension bolts 41. That is, when the large-diameter suspension bolt 41 is attached, the large-diameter suspension bolt 41 is accommodated between the pair of sandwiching pieces 4 as shown in FIG. 6 is brought into contact with the outer peripheral surface of the suspension bolt 41 and is held between the holding piece 4 and the base portion 3 by an elastic restoring force in a direction of reducing the diameter inward and held at a fixed position. When the small-diameter suspension bolt 41 is attached, the small-diameter suspension bolt 41 is fitted in the fitting recess 10 formed in the range of the arc portion 6 of the holding piece 4 as shown in FIG. Is abutted along the outer peripheral surface of the suspension bolt 41 and is held between the fitting recess 10 and the base 3 by an elastic restoring force in the direction of reducing the diameter inward and held at a fixed position.

  Here, as described above, the fitting recess 10 of each of the above embodiments is formed between the sandwiching pieces 4 in the base portion 3 or on the inner surface side of the arc portion 6 of the sandwiching piece 4. It may be formed on both sides, and in this case, the support 1 can be held on the suspension bolt 41 more stably.

  Moreover, although the support tool 1 in each said embodiment has shown what is selectively attached to two types of large and small suspension bolts 41 from which a diameter differs, for example, as shown schematically in FIG. In addition, by forming two types of fitting recesses, it is possible to selectably attach to three types of large, medium and small suspension bolts 41 having different diameters. That is, a fitting recess 10a that is in contact with the outer peripheral surface of the small-diameter suspension bolt 41a indicated by a solid line is formed in the range b of the center portion of the fitting recess, and a double-dotted line is formed in the range c on both sides of the fitting recess. A fitting recess 10b is formed that abuts along the outer peripheral surface of the illustrated medium-diameter suspension bolt 41b. Thereby, the outer peripheral surfaces of two types of suspension bolts are fitted into the fitting recess. The large-diameter suspension bolt 41c indicated by a two-dot chain line has an outer peripheral surface that abuts against the opening edge portions on the left and right sides of the fitting recess, and is similar to the other medium and small suspension bolts. It is pressed against the base 3 by the elastic restoring force, and is strongly held between the base 3 and the holding piece 4. As a result, it is possible to stably attach to three types of suspension bolts of large, medium and small with one type of support 1.

  Next, although the support part 21 of the said embodiment has shown what supports the cable 51, for example, when supporting a pipe etc., the support part formed in the cyclic | annular band body like FIG. 31 can be assembled. That is, since the support portion is detachably attached to the attachment portion 2, only the support portion can be easily replaced with one suitable for the type of the long material. Thereby, the attachment part 2 can be used in common and a component cost can be reduced.

  Moreover, although the support tool 1 of the said embodiment forms the attachment part and the support part in the different body, and connects this, it is not restricted to this, For example, as shown in FIG. The attachment part 2 and the support part 32 may be integrated. The support portion 32 can be fixed by binding a cable 51 or a tubular body by attaching a binding band 34 using a guide piece 33 integrally formed at the lower portion as a guide.

  Further, the upright portion 5 may not be vertical but may be bent and rise immediately from the base portion 3.

  In addition, in the present embodiment, the suspension bolt 41 is taken as an example of the round bar material, but the present invention can be similarly applied to other deformed reinforcing bars.
