Description

  The present invention relates to the construction of structures and the like for wiring and piping of cables and the like, and conduits, water supply pipes, steam pipes and the like for housing and protecting cables and the like along the walls of buildings. The present invention relates to a fixing device for wiring and piping material fixed to a material.

  Conventionally, there is a fixing device that is fixed to a construction material such as a reinforcing bar or a steel structure for wiring and piping this kind of wiring and piping material along the wall surface, ceiling surface, etc. of buildings such as factories, premises and warehouses. It is used. This fixing device is generally composed of a support that supports the wiring / piping material and a fixing device that is fixed to the construction material, and examples thereof include those described in JP-A-2002-339919. .

  FIG. 8 shows a fixing device 41 described in the publication, etc., and this fixing device 41 is composed of a fixture 42 fixed to the construction material 2 and a two-part body, and the conduit 4 as a piping material is attached from both sides. The support tool 43 is supported by being sandwiched and fixedly connected to the fixing tool 42. The fixing device 42 is formed in a U-shaped plate shape, has a circular locking hole 44, the fixing bolt 31 screwed into a screw hole 45 a opened in one opposing plate-like portion 45, and the other It is fixed to the flange 2a etc. of the building material 2 by being gripped by the plate-like portion 46. On the other hand, the support tool 43 has a locking claw 47 inserted into the locking hole 44 of the fixing tool 42 and locked at one end of each of the arc band plate member 43a and the arc band plate member 43b divided into two. Is provided. Further, the support tool 43 clamps the conduit tube 4 from both sides by tightening the other end portions close to each other via the connecting bolt 32, and a pair of locking claws 47 provided at the one end portion are expanded. The fixing fixture 42 is connected and fixed to the fixing fixture 42 by being pressed and locked to the peripheral wall surface 44 a of the locking hole 44 of the opening fixture 42.

The fixing device 41 configured as described above fixes the fixing tool 42 to the construction material 2, locks the locking claw 47 of the support tool 43 into the locking hole 44 of the fixing tool 42, and fixes the support tool 43. By connecting and fixing to the fixture 42 and holding the electric conduit 4 with the support fixture 43, it can be piped along the wall surface, ceiling surface, etc. of the building.
JP 2002-339919 A

  However, when the conduit 4 is long and flexible, it is generally stored and carried in a wound state. For this reason, since the electric wire 4 is wound by the fact that it was wound, the restoring force which tries to return to the original winding state elastically remains. On the other hand, in the fixing device 41 described in Japanese Patent Laid-Open No. 2002-339919, the locking hole 44 of the fixing tool 42 is formed in a circular shape, and the support tool 43 locked in the locking hole 44 is engaged. The pawl 47 is considered to have a press-contact portion that is pressed against the peripheral wall surface 44 a of the locking hole 44 in an arc shape corresponding to the shape of the locking hole 44. Therefore, the support tool 43 is in a state where it can easily rotate with respect to the fixing tool 42 about the connecting portion. For this reason, after the conduit 4 is piped along the wall surface, ceiling surface, etc. of the building using the fixing device 41 described in the above publication, the support 43 is supported by the elastic restoring force due to the curl remaining on the conduit 4. May rotate relative to the fixture 42.

  That is, by strongly tightening the connecting bolt 32, the locking claw 47 of the support tool 43 is strongly pressed against the peripheral wall surface 44a of the locking hole 44 of the fixing tool 42, and the support tool 43 is firmly connected and fixed to the fixing tool 42. Since the locking hole 44 of the fixing tool 42 is formed in a circular shape and the locking claw 47 of the support tool 43 is considered to be formed in an arc shape, the locking claw 47 of the support tool 43 is shaped in shape. It is easy to rotate along the peripheral wall surface 44 a of the locking hole 44. In general, the elastic restoring force due to the winding habit of the conduit 4 is considerably large, and this tendency is strengthened especially when the tube diameter is large. In such a situation, when the fixing of the support tool 43 to the fixing tool 42 can be loosened or some impact is applied to the conduit 4, the press contact portion of the locking claw 47 of the support tool 43 becomes the locking hole of the fixing tool 42. As a result, the support member 43 is rotated by a predetermined angle. For this reason, at the time of connecting and fixing, for example, as shown in FIG. 9A, the support tool 43 is fixed in a vertical state with respect to the fixing tool 42, and the conduit 4 is laid in a horizontal state. As shown in FIG. 9 (b), the rotating and tilting may cause the conduit 4 to meander and become unsightly.

  Further, as described above, the conduit 4 has a curl, the locking hole 44 of the fixing tool 42 is formed in a circular shape, and the locking claw 47 of the support tool 43 is formed around the locking hole 44. It is easy to rotate along the wall surface 44a. For this reason, when piping work is performed along the wall surface, ceiling surface, etc. of the building, the position of the conduit tube 4 is not shifted by the curl after the conduit tube 4 is placed in a certain posture such as a horizontal state with one hand. While holding this carefully, the connecting bolt 32 must be tightened using a tool with the other hand, and the support tool 43 must be connected and fixed to the fixing tool 42 while holding the conduit 4 with the support tool 43. There wasn't. Therefore, the installation work is cumbersome and troublesome. Further, when the support tool 43 is positioned and connected and fixed at a predetermined angle with respect to the fixing tool 42 and the conduit 4 is piped in a fixed posture, the locking hole 44 of the fixing tool 42 is formed in a circular shape. For this reason, it is difficult to accurately align with a predetermined horizontal state, for example, and the pipe may be inclined in a tilted state unless a jig or the like is used. In that case, it was necessary to loosen and fix the connecting bolt 32 again.

  In view of this, the present invention is designed so that after the installation on the construction material, the support is rotated by the elastic restoring force due to the winding habit of the wiring / pipe material, the mounting angle with respect to the fixture is shifted, and the alignment state of the wiring / pipe is disturbed. In addition, the support tool can be accurately positioned and fixed at a predetermined angle with good workability at the time of installation on the construction material, so that the wiring / piping material can be easily wired in a predetermined arrangement state. An object of the present invention is to provide a fixing device for wiring and piping material that can be piped.

  The fixing device for wiring / piping material according to claim 1 includes a fixing member that is provided with a polygonal locking hole, is fixed to the construction material, and a two-part body, and is provided so as to face each other at one end portion thereof. A pair of locking claws are inserted into the locking holes of the fixing tool, expanded in opposite directions to each other, and pressed and locked to the peripheral wall surface of the locking hole to be connected and fixed to the fixing tool, And a support that supports the wiring / pipe material from both sides. Then, after the support tool is connected and fixed to the fixing tool, an external force is applied to the support tool to forcibly rotate the connecting part with the fixing tool as a shaft. The claw is pressed against the peripheral wall surface of the locking hole of the fixing tool, moves in the diameter reducing direction along the peripheral wall surface, gets over the adjacent diameter expanding direction while being close to each other, and elastically returns to be engaged in the diameter expanding position. The support member is formed such that a phase with respect to the fixing member having the connecting portion as an axis is displaced stepwise corresponding to a polygonal shape of the locking hole.

  Here, the wiring / piping material is long and has a flexibility made of synthetic resin, rubber, etc., and has a curl for storing and carrying it in a wound state, and unwinds and extends it. The main object is the one that bends. A pair of locking claws of the support tool is provided at one end of each of the two divided bodies so as to face each other, and a pair of the support tools is provided as a whole.

  A pair of opposing locking claws are pressed against the peripheral wall surface of the locking hole, that is, the inner peripheral wall surface of the fixing tool in opposite directions, and the support tool is held and fixed to the fixing tool by the pressing force. Therefore, although the locking claw of the support is prevented from being pulled out from the locking hole of the fixing tool, the locking portion with the locking hole, that is, between the supporting tool and the fixing tool, depending only on the pressure contact force. It is difficult to prevent relative rotation with respect to the locking hole with the connecting portion as an axis. If the locking claw is excessively pressed, the pressure contact portion is damaged.

  However, since the locking hole of the fixture according to claim 1 is formed in a polygonal shape, the interval from the rotation center to the peripheral wall surface of the locking hole, that is, the side of the polygon is the rotation of the corner of the polygon. Less than the radius. For this reason, if the pair of locking claws try to rotate, they receive a compressive force from the peripheral wall surface of the locking hole and receive a large sliding resistance from the peripheral surface of the locking hole. Will be blocked. As a result, after fixing the fixing tool to the construction material and connecting and fixing the support tool to the fixing tool, the support tool is relatively relative to the fixing tool with respect to the fixing tool due to the elastic restoring force due to the curl of the wiring / pipe material. It is possible to prevent the tilting from being shifted from the predetermined mounting angle.

  The locking hole of the fixing tool is formed in a polygonal shape, and the distance from the center to the side of the locking hole is smaller from the center to the corner, and the diameter decreases toward the middle of the side of the locking hole. It has become a thing. Therefore, after the support tool is connected and fixed to the fixing tool, when the support tool is forcibly rotated about the connecting portion with the fixing tool, the pair of locking claws of the support tool is fixed to the fixing tool. While being pressed by the peripheral wall surface of the locking hole, the roller moves in the diameter reducing direction along the peripheral wall surface and reaches the center position of the side while being close to each other. In this state, the locking claw is elastically deformed. Next, the center position is overcome in the adjacent diameter-expanding direction, elastically returns to the original stable state, and is locked at a certain position where the diameter has been expanded. Along with this, the phase of the support with respect to the fixing tool with the connecting portion as an axis, that is, the mounting angle, is displaced stepwise corresponding to the polygonal shape of the locking hole. As a result, even after the support tool is connected and fixed to the fixing tool, the support tool is gripped by hand, and the external force in the rotational direction is forced against the sliding resistance received from the peripheral wall surface of the polygonal locking hole. , The support can be rotated to set and adjust to a predetermined mounting angle. In addition, in the case where the locking hole of the support is square, depending on the size and the shape of the locking claw, forcible rotation may be difficult by applying an external force. Therefore, the locking hole of the fixing tool and the locking claw of the support tool need to be appropriately sized and shaped.

  Specifically, the fixing device and the support device can be configured as claimed in claim 2 or claim 3. However, the wiring and piping material fixing device according to claim 1 is not limited to these configurations.

  According to a second aspect of the present invention, there is provided a fixing device for wiring / piping material, which further embodies the structure of the fixing member and the supporting member according to the first aspect. Then, it is fixed to the construction material by gripping it with a fixing bolt screwed into a screw hole opened in one opposing plate-like portion and the other plate-like portion. The support member is formed of an arc-shaped belt plate-like two-part body, and a pair of locking claws formed by folding back one end portions to the opposite sides are inserted into the locking holes of the fixing device. It expands in the opposite direction and is pressed and locked to the peripheral wall surface of the locking hole to be connected and fixed to the fixture, and supports the wiring / pipe material sandwiched from both sides. Similarly, the locking hole of the fixture is formed in a polygonal shape.

  According to a third aspect of the present invention, there is provided a wiring / piping material fixing device in which the locking claw of the support tool of claim 1 is pressed against and locked to the peripheral wall surface of the locking hole of the fixing tool, and the support tool is connected and fixed to the fixing tool. The structure is a more specific configuration, and the support is configured by wiring the flanges provided opposite to each other at the other end portions of the two-divided body by tightening the connecting bolts inserted through these flanges.・ Pinching the piping material, and a pair of locking claws provided at one end of each of the pipes expands and is pressed against and locked to the peripheral wall surface of the locking hole of the fixing tool, and is fixedly connected to the fixing tool. The

  The fixing device for a wiring / piping material according to claim 4 includes: a supporting tool in which the locking hole of the fixing tool and the locking claw of the supporting tool are connected and fixed to the fixing tool by an elastic restoring force due to the winding hook of the wiring / pipe material It is formed in a shape and size that prevent the connecting portion with the fixture from rotating about the axis. For example, if the locking hole of the support tool is a polygonal shape close to a circle or is small, the support tool can be easily rotated around the connecting part with the fixing tool by the elastic restoring force due to the winding of the wiring / pipe material. May end up. Therefore, the locking hole of the fixing tool and the locking claw of the support tool need to be appropriately sized and shaped.

  In the wire / pipe material fixing device according to the fifth aspect, the locking hole of the fixing tool is formed in an even-angled shape. As a result, the pair of opposing locking claws are aligned with the opposing sides or corners of the locking hole of the fixture, and fit into the position of the peripheral wall surface.

  In the wiring / piping material fixing device according to the sixth aspect, the locking hole of the fixing tool is formed in an octagonal shape.

  In the wire / pipe material fixing device according to claim 7, the press-contact portion with the peripheral wall surface of the locking hole of the fixing tool in the locking claw of the support tool is bent corresponding to the polygonal shape of the locking hole. .

  According to the first aspect of the present invention, since the locking hole of the fixing tool is formed in a polygonal shape, even if the support tool tries to rotate relative to the fixing tool with the connecting portion as an axis, the engagement of the support tool. Since the pawl receives a large sliding resistance due to contact with the polygonal side of the locking hole, the rotation is prevented. Therefore, after fixing the fixing tool to the construction material and connecting and fixing the support tool to the fixing tool, the support tool is rotated relative to the fixing tool by the elastic restoring force due to the winding curl of the wiring / pipe material. It is prevented from being tilted out of the mounting angle. This prevents wiring or piping materials from being routed or plumbed along the walls of the building, etc., immediately or gradually tilting the support, and the wiring or piping materials meandering to prevent the alignment from being disturbed and deteriorating in appearance. be able to.

  Also, when performing wiring and piping work along the wall or ceiling of the building, fix the fixture to the construction material, connect the fixture to the fixture, and then hold the fixture by hand. The support tool can be rotated to easily set and adjust to a predetermined mounting angle by forcibly applying external force in the rotating direction against the sliding resistance received from the peripheral wall surface of the polygonal locking hole. can do. Therefore, it is not necessary to carefully hold the wiring / pipe material in a fixed position while the support is connected and fixed to the fixing tool. Because it can be easily corrected and adjusted by moving, wiring and piping can be wired and piping with good workability in a state where the wiring and piping materials are arranged in a certain state.

  Furthermore, since the locking hole of the fixing tool is formed in a polygonal shape, the locking claw of the support tool is stably held at a fixed position corresponding to the polygonal shape of the locking hole. As a result, the polygonal shape of the locking hole serves as a guide, making it easy to position the wiring / piping material in a predetermined mounting state such as a horizontal state or a vertical state, and wiring and piping at a predetermined mounting angle accurately. Can do.

  The invention of claim 2 further embodies the structure of the fixing tool and the support tool of claim 1, and has the same effect as that of claim 1, and in particular, the wiring / pipe material reliably with a simple structure. Can be supported.

  The invention of claim 3 further embodies the structure in which the locking claw of the support tool of claim 1 is pressed and locked to the peripheral wall surface of the lock hole of the fixing tool and the structure in which the support tool is connected and fixed to the fixing tool. In particular, with a simple configuration in which the other ends of the two parts of the support are fastened together by connecting bolts inserted through them, the wiring / pipe material is sandwiched, and at the same time, a pair of locking claws are attached. The support member can be connected and fixed to the fixing member by being expanded and pressed against the peripheral wall surface of the locking hole of the fixing member.

  The invention according to claim 4 prevents the support member connected and fixed to the fixture by the elastic restoring force due to the curl of the wire / pipe material from rotating about the connecting portion with the fixture. After wiring and piping the piping material in a predetermined state along the wall of the building, etc., immediately or gradually tilt the support, the wiring and piping material meanders, the alignment is disturbed, and the appearance deteriorates. Can be prevented.

  According to the fifth aspect of the present invention, since the locking holes of the fixing tool are formed in even-numbered corners, the opposing pair of locking claws are matched with the opposing sides or corners of the locking holes of the fixing tool. Can be stably held at a fixed position.

  In the invention of claim 6, since the locking hole of the fixture is formed in an octagonal shape, the wiring / pipe material can be arbitrarily set to any one of a horizontal state, a vertical state, and an inclined state of 45 degrees. You can select and align them easily.

  According to the seventh aspect of the present invention, the press contact portion of the locking claw of the support tool with the peripheral wall surface of the locking hole of the fixing tool is bent corresponding to the polygonal shape of the locking hole. Combined with the action of the polygonal shape of the locking hole, the support member connected and fixed to the fixture by the elastic restoring force due to the winding of the wiring / pipe material rotates about the connecting portion with the fixture. Can be prevented more reliably.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 6. Here, FIG. 1 shows a fixing device according to an embodiment of the present invention, FIG. 2 is a state of connecting and fixing the fixing tool and the supporting tool of FIG. 1, and FIG. The locking relationship is shown.
1 to 6, the fixing device 1 includes a fixing tool 11 fixed to the construction material 2 and a two-part body. The fixing device 1 is connected and fixed to the fixing tool 11 and sandwiches the wiring / pipe material from both sides. And a supporting tool 21 to be supported. A regular octagonal locking hole 18 is formed in the fixture 11. Further, the support tool 21 is provided with locking claws 24 that are opposed to each other after assembly and are inserted into the locking holes 18 of the fixing tool 11 and pressed against and locked to the peripheral wall surfaces at one end of each divided body. Here, the wiring and piping material applied in the present embodiment is a long and flexible corrugated conduit 3 having a circular cross section that accommodates and protects an electric wire such as a cable therein, and has an annular shape. The ridges and the annular valleys are alternately formed, and the outer peripheral surface has an uneven shape, which is intended for a relatively large diameter.

  The fixing device 1 will be described in more detail. First, as shown in FIG. 4, the fixing device 11 is formed by bending a metal plate material such as a steel plate to form a substantially U-shaped plate as a whole. A flange 15 is provided at both ends in the width direction of the plate-like portion formed by bending the flat plate into a U-shaped plate so as to stand upright on the inner side of the fixture 11 so as to protrude to the full length. Further, a rib 16 is provided at the entire boundary portion between the plate-like portion and the flange 15 to increase the overall rigidity. A screw hole 17 into which a fixing bolt 31 is screwed is opened at substantially the center of one plate-like portion 12 facing the fixing tool 11. A locking hole 18 having a regular octagonal shape is opened at the center of the other plate-like portion 13 facing each other and the connecting plate-like portion 14 between the opposite plate-like portions and connecting them. . Furthermore, the front end surface of the flange 15 erected on both ends of the other plate-like portion 13 is formed in a sawtooth shape. The fixture 11 is formed by gripping the flange 2a of the construction material 2 with the fixing bolt 31 screwed into the screw hole 17 of the opposite plate-like portion 12 and the flange 15 of the other plate-like portion 13. It is designed to be fixed to the construction material 2.

  Next, as shown in FIG. 5 and FIG. 6, the support 21 is made of a long arc strip plate member 22 and a short arc strip plate member 23 which are made of metal and formed in an arc strip shape. It consists of two parts, and when both arc strip members are combined, an annular strip member is formed so that the corrugated conduit 3 can be sandwiched and supported from both sides. One end portion of each of the arc strip members is formed in a tapered shape, and the distal end side thereof is folded back to the opposite side to be inserted and locked in the locking hole 18 of the fixture 11. A locking claw 24 is formed. Each of these locking claws 24 forms a pair of locking claws that press against the peripheral wall surface 19 of the locking hole 18 of the fixture 11 in opposite directions. Each of the locking claws 24 has an outer surface 25 a that is in pressure contact with the peripheral wall surface 19 of the locking hole 18 of the fixture 11 at the folded-back bent portion 25, and the bent portion 25 is connected to the locking hole 18. It also serves as a pressure contact portion with the peripheral wall surface 19.

  Further, the bent portion 25 is bent at two locations corresponding to the shape of the locking hole 18 of the fixture 11 and is bent with respect to the central portion 24a as shown by a in FIG. Further, the bending angle of both side portions 24b is set to 48 °. The inside angle of the regular octagon of the locking hole 18 of the fixture 11 is 135 °, and correspondingly, it is 48 ° with a slight margin. The distal end portion of the locking claw 24 is formed in a substantially arc shape so that it can be easily inserted into the locking hole 18. Each arc strip member is provided with reinforcing ribs 26 along the arc direction. However, the rib 26 may be unnecessary when the support 21 is constant, such as a small one.

  On the other hand, the other end portion of each arc strip member is bent outward, and a flange 27 is formed at the tip portion. Each flange 27 forms a pair of flanges facing each other in parallel. Furthermore, in one of the present embodiments, a long hole 27a through which the connecting bolt 32 is inserted is formed at the center of the flange 27 on the long arc strip member 22 side. Then, a screw hole 27b into which the connecting bolt 32 is screwed is formed at a position of the flange 27 of the short arc strip member 23 facing the long hole 27a of the one flange 27. The screw hole 27b may be an insertion hole when the flange 27 is thin, and the connecting bolt 32 may be tightened using a nut.

  The support tool 21 is formed in this manner, and after the pair of locking claws 24 and 24 are inserted into the locking holes 18 of the fixing tool 11, the support tool 21 is inserted into the long hole 27 a of the flange 27 of the arc strip member 22. By tightening the connecting bolt 32 screwed into the screw hole 27b of the arc strip member 23 and bringing the flanges 27 close to each other, the bent portions 25 of the locking claws 24 expand in opposite directions, and the fixture 11 The locking hole 18 is pressed against and locked to the peripheral wall surface 19 to be connected and fixed to the fixture 11, and the corrugated conduit 3 is supported by being sandwiched from both sides.

  Here, if the diameter of the locking hole 18 of the fixing tool 11 is too small, the sliding resistance of the locking hole 18 as a whole becomes small, and the locking claw 24 of the support tool 21 has a corrugated conduit. May be rotated by the elastic restoring force of the curl. Moreover, when the diameter of the latching claw 24 is too large, the strength of the plate-like portion of the fixture 11 is lowered. Accordingly, the diameter of the locking hole 18 is set to an appropriate size in consideration of the size of the corrugated conduit 3 and the like. In the present embodiment, in the fixture 11 having a width of 30 mm, the locking hole 18 is set to have a distance between opposite sides of 13.8 mm.

  In addition, for example, when the bend radius of the two bent portions in the bent portion 25 is large with respect to the locking claw 24 of the support tool 21, the support tool 21 is similarly rotated by the winding rod of the corrugated conduit 3. May end up. Accordingly, the locking hole 18 of the support 21 is similarly set to an appropriate shape.

Next, a method of piping the corrugated conduit 3 along the wall surface of the building using the fixing device 1 configured as described above will be described.
First, the fixing bolt 31 is screwed into the screw hole 17 of the one plate-like portion 12 of the fixing tool 11 facing, and the flange 2a or the like of the construction material 2 is opposed to the tip of the fixing bolt 31 and the other plate-like portion 13 of the opposite. The fixing tool 11 is fixed to the construction material 2 by gripping with the flange 15 formed in a sawtooth shape.

  Next, while holding the corrugated conduit 3 in a predetermined arrangement direction by sandwiching the two-divided arc strip member of the support 21 from both sides of the outer surface of the corrugated conduit 3, the flange 27 of the arc strip member is held. After the connection bolt 32 is attached to the long hole 27 a and the screw hole 27 b, the pair of locking claws 24, 24 are inserted into the locking holes 18 of the fixture 11. At this time, since one locking hole 18 of the fixture 11 is provided in each of the plate-like portion 13 and the connecting plate-like portion 14, the support 21 selects one of the two directions orthogonal to the fixture 11. Can be installed. Next, as shown by the arrow in FIG. 2, when the connecting bolt 32 is tightened to bring the flanges 27 close to each other, the bent portion 25 of the locking claw 24 is as shown by the arrow in FIG. 2 and FIG. In response to the forces in the direction of expanding to the opposite sides, they are strongly pressed and locked against the peripheral wall surface 19 of the locking hole 18 of the fixture 11 corresponding to the tightening force of the connecting bolt 32. Thereby, the support tool 21 is firmly connected and fixed to the fixing tool 11. At the same time, the corrugated conduit 3 is firmly clamped from both sides by the arc strip member 22 and the arc strip member 23 of the support 21 and supported by the support 21.

  Here, after the support tool 21 is connected and fixed to the fixing tool 11, when the corrugated conduit 3 is piped out of a predetermined arrangement direction, the support tool 21 is gripped by hand, and a regular octagonal shape is formed. The external force in the rotational direction is forcibly applied against the sliding resistance received from the peripheral wall surface 19 of the locking hole 18, and the support 21 is displaced stepwise corresponding to the regular octagonal shape of the locking hole 18. The corrugated conduit 3 can be adjusted in a predetermined arrangement direction by rotating and correcting to a predetermined mounting angle. At this time, the pair of locking claws 24, 24 of the support tool 21 move in the diameter reducing direction along the peripheral wall surface 19 while being pressed by the peripheral wall surface 19 of the locking hole 18 of the fixing tool 11. Then, while approaching each other, it overcomes the adjacent diameter-expanding direction and elastically recovers and locks in the diameter-expanded position. This point will be further described later.

  In the above procedure, the operation of fixing the fixing tool 11 to the construction material 2 can be performed after the support tool 21 is connected and fixed to the fixing tool 11. However, since it has to be fixed to the construction material 2 while holding the fixing tool 11 and the support tool 21, it becomes somewhat difficult to work.

Next, the operation of the fixing device 1 of this embodiment will be described.
In the fixing device 1, the locking holes 18 of the fixing tool 11 are formed in a regular octagonal shape, so that the pair of locking claws 24, 24 of the support tool 21 are caused by the elastic restoring force due to the curl of the corrugated conduit 3. Even if the rotation is attempted, as described above, in FIG. 3C, the distance L from the rotation center O to the octagonal side 18a of the locking hole 18 is smaller than the rotation radius R of the corner 18b. 3B, the bent portions 25 of the locking claws 24, that is, the end portions 25b of the pressure contact portions or the two bent portions 25c are formed on the side 18a near the corner portions 18b of the locking holes 18. As shown in FIG. At the end, a compression force is received from the peripheral wall surface 19 of the locking hole 18, and a large sliding resistance is generated to prevent the rotation. As a result, the fixing tool 11 is fixed to the construction material 2 and the support tool 21 is connected and fixed to the fixing tool 11, and then the support tool 21 is fixed to the fixing tool 11 by the elastic restoring force caused by the curl of the corrugated conduit 3. It is possible to prevent the corrugated conduit tube 3 from being disturbed by rotating the connecting portion relative to the shaft and tilting it from a predetermined mounting angle.

  Further, when performing construction work for wiring and piping along the wall surface, ceiling surface, and the like of the building, the fixing tool 11 is fixed to the construction material 2, the support tool 21 is connected and fixed to the fixing tool 11, and then the fixing tool 11. When the mounting angle of the support tool 21 with respect to is shifted, the support tool 21 is gripped by hand and is forced to move against the sliding resistance received from the peripheral wall surface 19 of the octagonal locking hole 18. Apply external force. Then, the pair of locking claws 24, 24 of the support tool 21 are pressed by the compressive force of the peripheral wall surface 19 of the locking hole 18, and retracted while elastically deforming to the inner side of the locking hole 18. Along the peripheral wall surface 19, toward the intermediate position of the side 18 a of the locking hole 18, and reaches the central position of the side 118 a while being close to each other. In this state, the locking claw is elastically deformed. Next, the center position is overcome in the adjacent diameter-enlarging direction, the elastic state is restored to the original stable state, and the center position is locked at the adjacent diameter-expanded fixed position. Along with this, the support 21 can be displaced stepwise in accordance with the polygonal shape of the locking hole 18 in terms of the phase, that is, the mounting angle with respect to the fixture 11 having the connecting portion as an axis.

  Here, in the support tool 21 formed in an annular shape, the pair of locking claws 24 and 24 can be close to each other because the support tool 21 is formed by the arc belt plate member 22 and the arc belt plate member 23. Since it is formed in two parts, it can be elastically deformed at the bent portion of the flange 27 bent at the other end portion of each arc strip member, and therefore at these portions. This is because dimensional changes due to proximity can be absorbed.

  Accordingly, even after the support tool 21 is connected and fixed to the fixing tool 11, the support tool 21 is rotated while being gradually displaced by 45 ° corresponding to the regular octagonal shape, and is easily set to a predetermined mounting angle. Can be adjusted. As a result, it is not necessary to carefully hold the corrugated conduit 3 at a fixed position while the support tool 21 is connected and fixed to the fixing tool 11. It can be rotated to easily correct and adjust the position. Thereby, the corrugated conduit 3 can be piped with good workability in a certain aligned state.

  Further, since the locking hole 18 of the fixing tool 11 is formed in a regular octagonal shape, the locking claw 24 of the support tool 21 is stabilized at a fixed position corresponding to the shape of the locking hole 18, that is, at intervals of 45 °. Held. As a result, the shape of the locking hole 18 serves as a guide, and the support tool 21 can be arbitrarily accurately and easily positioned relative to the fixing tool 11 at any mounting angle of a horizontal state, a vertical state, and a 45 ° inclined state. Thus, the corrugated conduit 3 can be reliably piped in a predetermined arrangement state.

  By the way, as shown in FIG. 3B, the pair of locking claws 24, 24 of the support tool 21 has a pair of central portions 24 a, 24 a aligned with the opposing sides 18 a, 18 a of the locking hole 18. Although it is stably held at a fixed position, the present invention is not limited to this. For example, as shown in FIG. 3 (d), the fixed positions are matched with the opposite corners 18b, 18b of the locking hole 18. It can also be held stably. In FIG. 3D, each locking claw 24 is formed in an arc shape or an elliptical arc shape having a larger radius of curvature than the locking hole 18. This is because when the locking claw 24 is formed in an arc shape, even if the locking claw 24 is rotated, the end portion does not hit the side 18a of the locking hole 18 and is not blocked by the side 18a. This is because it easily rotates.

  Also, as shown in FIG. 3 (e), each locking claw 24 is bent into a square shape, and this is matched with the opposite corners 18b, 18b of the locking hole 18 so as to be stably at a fixed position. It may be held.

  Furthermore, although the locking hole 18 of the fixture 11 of the above embodiment is formed in a regular octagonal shape, it is not necessarily limited to this, and may be in an octagonal shape other than this. It is good also as a shape and a square shape. Moreover, it is not restricted to these even angle shapes, You may form in odd angle shapes. However, in order to forcibly rotate the support tool 21 after the support tool 21 is connected and fixed to the fixing tool 11 and to prevent the support tool 21 from rotating due to the winding of the corrugated conduit 3, A regular octagonal shape is optimal.

FIG. 7 illustrates the shape of the locking claw 24 of the support tool 21 when the locking hole 18 of the fixing tool 11 is formed in a square shape. If the locking hole 18 has a quadrangular shape, the angle between the two sides is 90 °, and it is bent abruptly. Therefore, after the support tool 21 is connected and fixed to the fixing tool 11, the support tool 21 is forcibly rotated. Requires considerable rotational power. However, as shown in FIG. 7, the force required for rotation can be made small by forming the latching claw 24 in the shape of a plate bent at two locations.
For this reason, in order to forcibly rotate the support tool 21 and prevent the support tool 21 from rotating due to the winding rod of the corrugated conduit 3, in addition to the locking hole 18, the support tool It is also necessary to consider the shape of the 21 locking claws 24.

  Further, the locking hole 18 of the fixture 11 is formed in a straight arc shape on each side 18a, but may be formed in an arc shape that curves inward or outward. Furthermore, fine serrated irregularities may be formed on the peripheral wall surface 19 of the locking hole 18, and in this case, resistance to rotation between the locking claw 24 and the peripheral wall surface 19 of the locking hole 18 is reduced. Can be bigger.

  And a pair of latching claws 24 and 24 of support implement 21 of the above-mentioned embodiment may mutually differ in shape. Further, the locking claw 24 is bent at 48 ° at two locations of the bent portion 25 corresponding to the locking hole 18 of the fixture 11, but is not limited to this angle. The bent portion 25 may be formed in an arc shape as described above without being bent.

  In addition, the support 21 of the above embodiment is formed by a two-part body of a long arc strip member 22 and a short arc strip member 23, but a pair of symmetrical semicircular arcs. You may form in the 2 division body of a strip member.

  Moreover, although the fixing tool 11 and the support tool 21 are made of metal, they are not limited to this, and can be made of a hard synthetic resin containing reinforcing fibers.

  Furthermore, although the fixing device 1 of the above embodiment uses the corrugated electric conduit 3 having a circular cross section as a wiring / pipe material, it can be similarly applied to a straight tube or a rectangular cross section. Of course, it can also be used to support non-flexible wiring and piping materials.
