Description

  The present invention has a bottom surface portion and a side surface portion, and wiring that draws the wiring / piping material into a wiring / piping material receiving member capable of laying wiring / piping material such as a cable, a water supply pipe, and a hot water supply pipe on the side surface portion -It is related with a piping material drawing-in apparatus and a drawing tool.

  Various wiring / piping material receptacles are used for laying wiring / piping materials in factories, buildings, etc., and wiring / piping material receptacles having bottom and side portions are usually wired / piping. A material that is laid by placing the material on the bottom is used, but a so-called vertical receiver is used in which the wiring / pipe material is attached to the side by installing it vertically from the standpoint of installation space, etc. Sometimes. A technique related to this type of vertical wiring / pipe material holder is disclosed in, for example, Japanese Utility Model Publication No. 53-51998.

  The wiring / pipe material holder disclosed in Japanese Utility Model Publication No. 53-51998 has a plurality of holes in the vertical mounting surface, and a plurality of cables are bound by passing a band body or a bind wire through the holes. , And can be mounted on the vertical mounting surface.

Japanese Utility Model Publication No. 53-51998

  However, the wiring / pipe material holder disclosed in Japanese Utility Model Publication No. 53-51998 is a hole in which a binding band or the like is provided on the vertical mounting surface at predetermined intervals while holding the cable each time the cable is laid. It has to be bundled through, and it has been complicated and time-consuming work. In particular, when a cable to be laid is long, it is a great burden.

  For this reason, once the cable is drawn onto the bottom surface of the wiring / pipe material holder, it is lifted and placed on the side surface of the hook member that is provided at predetermined intervals in the longitudinal direction. It is done. According to this, since it is not necessary to bind a plurality of cables with a binding band or the like each time, it is possible to reduce labor required for laying.

  However, the wiring / pipe material holder that is installed by laying this cable open to the side opposite to the side surface where the cable is replaced when the cable is pulled into the bottom surface of the wiring / pipe material holder. Therefore, the middle part behind the tip of the cable falls off from the opening, and particularly when the cable is pulled into the portion where the laying path is bent inward, the middle part easily falls off. Moreover, since the cable meanders with a curl etc., it may fall out from a side opening similarly. When the middle part of the cable falls off from the opening of the receiver in this way, that part hangs down in a curved state, and in that state the resistance is large and cannot be retracted. It must be returned to the department, which places a heavy burden on the installation work. Although it is conceivable to increase the width of the bottom surface of the wiring / pipe material holder in order to prevent it from falling off, there is an advantage of the so-called vertical holder that is used in a standing state using a narrow space. It will be lost.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. Here, FIG. 1 is a perspective view showing the wiring / pipe material drawing device of the embodiment of the present invention, and FIG. 2 is a drawing showing the drawing tool of FIG.

  1 and 2, the wiring / piping material drawing-in device 1 is mounted on the receiving device 11 from the outer surface side, with a receiving device 11 on which a cable C serving as wiring / piping material is placed and installed along the installation path. And a pull-in tool 31 used to prevent the cable C from falling off the receiver 11 and to draw the cable C into the pull-in path 17 of the receiver 11. The retracting path 17 is formed on the bottom surface portion 14 of the receiver 11, and the cable C is easily dropped at the portion where the laying path is bent inward when retracted. Attached to the bent portion 18. In addition, since the cable C meanders with a winding rod or the like, it may fall off even in the straight portion of the lead-in path 17, so that the pull-in tool 31 is appropriately attached to this straight portion. Here, the cable C is held in the laying direction while holding the tip portion of the cable C, and is laid in the lead-in path 17 of the receiver 11. It drops off from the path 17 and hangs down in a curved shape. Accordingly, the retracting tool 31 supports the intermediate portion of the cable C and prevents its dropout.

  First, the receiver 11 is configured by assembling vertical bars 12 and horizontal bars 13 made of a metal wire having a circular cross section into a lattice shape by welding or the like. The vertical stripes 12 are bent in a substantially U shape, are arranged at appropriate intervals in the laying direction, and are connected by horizontal stripes 13 arranged in a plurality of stages in the vertical direction. As described above, the receiving device 11 formed by assembling the vertical stripes 12 and the horizontal stripes 13 as a whole has a bottom surface portion 14, a side surface portion 15 erected on one side of the bottom surface portion 14, and the side surface portion 15. An upper surface portion 16 that protrudes horizontally in the upper end portion and faces the bottom surface portion 14 is provided, and a portion facing the side surface portion 15 on the other side of the bottom surface portion 14 is open. The upper surface of the bottom surface portion 14 is a drawing path 17 on which the cable C is drawn and placed. The receiver 11 is a so-called vertical receiver capable of laying the cable C on the side surface portion 15. Further, in FIG. 1, the receiver 11 is shown installed at the bent portion of the laying path, and the bent portion 18 is curved toward the other side of the bottom surface portion 14, that is, the opening side.

  Here, since the metal wire has a circular cross section, the cable C can be prevented from being damaged by contact during and after installation. However, the metal wire is not limited to a circular cross section, and various types such as a rectangular, hexagonal, elliptical, oval, etc. cross section can be used. When the cross section is rectangular, oval, etc., the contact area between the vertical bars 12 and the horizontal bars 13 increases, and the welding strength increases.

A roller 19 on which the cable C is placed on the upper surface is attached to a predetermined vertical bar 12 in the bottom surface part 14 of the receiver 11 so as to be rotatable about the metal wire of the vertical bar 12. Pulling resistance is reduced by sliding contact with C. The roller 19 may have any form. For example, a half-columnar half body 19a and a half body 19b divided into two in the axial direction, such as the roller shown in FIG. It can be fitted and assembled. The roller 19 having this configuration can be attached as a retrofit even after the receiving device 11 is formed. By attaching this roller 19, the force required to pull in the cable C is reduced and can be pulled in easily. However, the bottom surface portion 14 of the receiving fixture 11 may be as not attached to the roller 19, in this case, the bottom surface portion 14 becomes flat, the effect is obtained that is easily retractable cable C, and the roller 19 Whether to attach or not may be appropriately selected according to the actual installation situation.

  Further, a plurality of hook members 20 that are formed in a hook shape and on which the cable C is placed are attached to the side surface portion 15 of the receiver 11 at appropriate positions on the side surface portion 15. The hook member 20 hooks the upper key-like hooking portion 20a on the adjacent upper horizontal stripe 13 and then pivots downward to elastically adjoin the locking portion 20b formed of the lower elastic protrusion. By engaging with the horizontal bar 13 on the lower side, it can be installed between the horizontal bar 13 from the opening side of the support 11. Here, since the horizontal bar 13 is made of a metal wire having a circular cross section, the upper hooking part 20a is smoothly rotated downward while being hooked on the horizontal bar 13 and the lower hooking part 20b is adjacent to the lower baring part 20b. It can be locked to the transverse muscle 13. The cable C is placed on a substantially L-shaped placement portion 20 c that protrudes toward the opening side of the receiver 11. However, the hook member 20 may be attached to the longitudinal bars 12. In FIG. 1, the hook member 20 is arranged in two upper and lower steps on the side surface portion 15, and the cable C can be laid in two upper and lower steps on the side surface portion 15.

  The receiver 11 is suspended from a plurality of suspension bolts 61 suspended from the ceiling via suspension members 62. The hanger 62 is formed in a substantially L shape by bending a steel material having a substantially U-shaped cross section, and a plurality of substantially T-shaped notch grooves 62a are provided on both side surfaces on the vertical side. The horizontal bar 13 of the holder 11 is inserted through the opening 62a and is held by the lower part of the notch groove 62a.

  Next, the retraction tool 31 is attached in the vicinity of the retraction path 17 of the receiver 11, and as shown in FIG. 1 and FIG. A roller 39 is attached to a base member 32 formed in an L shape via a roller attachment member 36. A plurality of substantially T-shaped notch grooves 33a that are partially open on the side of the lead-in path 17 are provided on both side surfaces of the vertical portion 33 of the substantially L-shaped base member 32 at predetermined intervals in the vertical direction. In the figure, three are provided. Here, since a plurality of the cutout grooves 33 a are provided, the load of the retracting tool 31 is distributed and applied to the three horizontal bars 13, and the horizontal bars 13 that support the retracting tool 31 are provided on the pulling tool 31. It can be prevented from being deformed by a load. However, when the pull-in tool 31 is lightweight, when the force acting on the horizontal stripes 13 is small or the strength of the horizontal stripes 13 is high, the number of cutout grooves 33a can be reduced.

  A horizontal portion 34 extends from the lower end portion of the vertical portion 33 of the base member 32 toward the retracting path 17 of the receiver 11, and the horizontal portion 34 of the retractor 31 and the bottom surface portion 14 of the receiver 11. A space 35 with a predetermined interval is formed between the two. In addition, the notch groove 33a of the vertical part 33 of the said drawing tool 31 is corresponded to the attaching part which can be attached from the outer surface side of the receiving tool of a claim. Further, the horizontal portion 34 of the retracting tool 31 extends from the vertical portion 33 to the other side of the bottom surface portion 14, that is, the inner surface side of the receiving device 11 so that the roller 39 is disposed on the other side of the bottom surface portion 14 of the receiving device 11. This corresponds to the connecting portion of the claims.

  A roller mounting member 36 made of a steel material having a substantially U-shaped cross section is erected on the protruding front end side of the horizontal portion 34, and the upper end portion and the middle portion of the roller mounting member 36 are directed toward the drawing path 17 side, respectively. The flange 37 and the flange 38 projecting horizontally are integrally provided. A roller 39 that rotates about the vertical direction is pivotally mounted between the flange 37 and the flange 38 of the roller mounting member 36. The side surface of the roller 39 is attached at a height and a horizontal position where the roller 39 is in sliding contact with the cable C drawn into the lead-in path 17 of the receiver 11. A set screw member 40 is screwed to the bottom surface of the vertical portion 33 of the base member 32. The base member 32 and the roller mounting member 36 of the retracting tool 31 may be formed of synthetic resin or the like.

  The retracting tool 31 moves the vertical portion 33 of the base member 32 from the outer surface side of the receiving tool 11, that is, from the opposite side of the opening of the receiving tool 11 toward the side surface part 15 of the receiving tool 11, and the cutout groove 33 a. Is hooked on the horizontal bar 13 of the support 11 from the opening, and then the set screw member 40 is rotated to screw the screw part 40 a to the lower part of the horizontal bar 13. Thereby, the upper part of the notch groove 33a of the base member 32 is supported by the horizontal stripe 13 and the retraction tool 31 is attached to the side surface portion 15 from the outer surface side of the receiving tool 11.

  It is desirable that the horizontal bar 13 of the support 11 is retracted to the outer surface side of the vertical bar 12, that is, the rear side opposite to the opening of the bar 11 and welded to the vertical bar 12 for assembly. Further, the protrusions at the opening of the notch groove 33 a of the retracting tool 31, that is, the tips of both side surfaces of the base member 32 of the retracting tool 31 are forward of the vertical muscle 12, that is, receiving the retracting tool 31 to the receiving tool 11. It is desirable to form so that it does not protrude to the inner surface side of the tool 11. These are for preventing the base member 32 of the retractor 31 from coming into contact with the cable C and being damaged.

  Next, a method of laying a plurality of cables C by the wiring / pipe material drawing device of the present embodiment configured as described above will be described with reference to FIGS.

  First, as shown in FIG. 3, a laying rope (not shown) is connected to the tip of the first cable C, and is pulled from one end side to the other end side of the receiver 11 to be on the bottom surface portion 14 of the receiver 11. It draws in the lead-in path 17 of At this time, in the bent portion 18 that curves to the other side of the bottom surface portion 14 of the receiver 11, that is, the opening side, an intermediate portion behind the distal end portion of the cable C is brought closer to the inside of the bent portion 18 of the receiver 11. Although there is a possibility of dropping from the opening of the receiver 11, in this embodiment, since the retracting tool 31 is attached, the side surface portion of the cable C comes into contact with the roller 39 of the retracting tool 31 and falls off. Is prevented.

  Here, since the roller 39 of the retracting tool 31 is rotatably mounted with the vertical direction as an axis, the sliding contact resistance with the cable C is reduced and the retracting force can be reduced, so that it can be retracted easily. However, the roller 39 does not necessarily need to be attached, and a simple plate material, bar member, or the like may be provided upright as long as the cable C can be pulled in smoothly and easily. The roller 39 of the retracting tool 31 shields the lower part of the opening of the receiving tool 11 and prevents the cable C from falling off, and therefore corresponds to a drop-off preventing part in claims.

  Next, when the first cable C is drawn to the full length of the lead-in path 17, the cable C is left as it is from below as shown in FIG. It is lifted upward and placed on the upper hook member 20 disposed on the side surface 15 of the receiver 11. Here, the transfer of the cable C to the hook member 20 on the upper stage can be easily performed by lifting it using a hand or a lifting tool.

Next, the second cable C is drawn in the same manner as the first cable C, as shown in FIG. Also at this time, the second cable C is prevented from dropping from the opening of the receiving tool 11 by the roller 39 which is a drop preventing part of the retracting tool 31. When the drawing of the second cable C into the drawing path 17 is completed, the second cable C is transferred onto the lower hook member 20 of the receiving tool 11 in the same manner. Here, in FIGS. 3 to 5, the hook members 20 are provided in two upper and lower stages, but if they are provided in three or more stages, the third and subsequent cables C can be laid in the same manner. The final cable C may be transferred to the side surface portion 15 of the receiver 11, but may be laid in a state where the cable C is still drawn into the lead-in path 17.

As described above, the plurality of cables C are laid on the side surface portion 15 of the receiver 11 in a plurality of stages in the vertical direction. Note that a roller 19 for reducing the pulling force is attached to the metal wire of the vertical bars 12 of the bottom surface portion 14. However, as described above, if the pulling path 17 is flatter, it is easier to pull the roller 19. Can be omitted.

  Next, the operation of the wiring / pipe material drawing device 1 and the drawing tool 31 will be described.

  In the wiring / piping material drawing-in device 1, the drawing tool 31 is provided with a roller 39 as a drop-off preventing part. Therefore, when the cable C is drawn into the drawing-in path 17 on the bottom surface part 14, the cable C is connected to the receiving tool 11. It is prevented from falling off from the opening, and it is avoided that the middle part behind the tip of the cable C hangs down in a curved shape. As a result, there is no need to lift the falling portion of the cable C and return it to the bottom surface portion 14, and the cable C is smoothly drawn into the drawing path 17 of the receiver 11.

Further, if the retracting tool is attached to the bottom surface portion 14 of the receiving device 11 from the inner surface side of the receiving device 11, the retracting device projects on the bottom surface portion 14 and draws the cable C into the retracting path 17. It becomes a disturbed, but may not smoothly retracted, in the present embodiment, since the pull member 31 is attached to the outer surface of the receiving member 11 from the outer surface side of the bracket as 11, pull-passage 17 by the pull-in member 31 Retraction is not hindered. As a result, the cable C is drawn smoothly.

  Further, after the cable C is laid on the receiver 11, if the final cable C is placed on the retracting path 17 on the bottom surface portion 14 of the receiver 11, the retractor 31 is temporarily connected to the receiver 11. If it is attached from the inner surface side to prevent the retracting tool 31 from projecting from the receiving tool 11 after laying, or to reuse the retracting tool 31 for reuse, etc., Since it is installed below the cable C placed on the lead-in path 17, it cannot be removed unless the cable C is once lifted and moved upward. However, since the retracting tool 31 of this embodiment is attached from the outer surface side of the receiving tool 11 and is not installed on the lower side of the cable C in the retracting path 17, it is immediately retracted without lifting the cable C. The tool 31 can be removed from the receiver 11. Since the retracting tool 31 can be easily removed, the removed retracting tool 31 can be easily reused when another receiving tool is retracted.

  In addition, the retracting tool 31 is attached from the outer surface side of the receiving tool 11, and the roller 39 is merely in sliding contact with the side portion of the cable C, and does not support the heavy cable C from below. Therefore, it is not necessary to increase the special strength and rigidity, and it is possible to make it small, light and inexpensive.

By the way, in the said embodiment, the space 35 of the predetermined space | interval is formed between the bottom face part 14 of the receiving tool 11, and the horizontal part 34 of the drawing tool 31.
