Hereinafter, a wiring / piping material drawing tool and a drawing device according to an embodiment of the present invention will be described with reference to the drawings.
1 and 2, a wiring / piping material drawing device 1 includes a receiving tool 2 that accommodates a cable C as a wiring / piping material, and a drawing tool 11 attached to the receiving tool 2. The drawing tool 11 is attached to a position where the cable C is drawn in the longitudinal direction at the longitudinal end portion of the receiving tool 2. Here, the longitudinal direction of the receiver is a direction in which the wiring / pipe material is laid, and the width direction of the receiver described later refers to a direction orthogonal to the longitudinal direction.

  The receiver 2 is a so-called mesh-type receiver formed by assembling a plurality of metal wire rods in a mesh form vertically and horizontally by welding. The support 2 is composed of a plurality of circular cross-section metal wire rods arranged in the longitudinal direction with a predetermined interval in the width direction, and a predetermined interval in the longitudinal direction orthogonal to this. In this embodiment, the child wire 4 is made of a metal wire bent in a U-shape with a plurality of circular cross-sections arranged in the width direction, and the upper end of the child wire 4 is perpendicular to the longitudinal direction. And a pair of left and right cross-sectionally shaped oval shaped wire rods made of metal wire rods, which are integrally assembled by welding the intersecting portions of these wire rods. The main reinforcement wire 3 is cut at a position adjacent to the welding portion with the child reinforcement wire 4 at the longitudinal end portion of the support 2. Here, the parent reinforcing wire 3 and the deformed reinforcing wire 5 correspond to the “wire extending in the longitudinal direction of the receiver” in the claims, and the child reinforcing wire 4 is the “wire extending in the width direction of the receiver” in the claims. It corresponds to.

  The parent rebar wire 3 of the support 2 is disposed below the child rebar wire 4, and the deformed rebar wire 5 is disposed outside the child rebar wire 4. Further, the deformed reinforcing wire 5 is formed so that both side surfaces in the width direction are parallel to each other, thereby increasing the contact area with the child reinforcing wire 4 and increasing the joining strength by welding.

  As a whole, the support 2 is also formed by a bottom portion 6 on which the main reinforcement wire 3 and the child reinforcement wire 4 are disposed, and side portions 7 erected on both sides of the bottom portion 6. The bottom 6 forms a laying surface 8 on which the cable C is laid. An end portion on one side in the longitudinal direction of the receiving tool 2 serves as an outlet 9 through which the cable C accommodated therein is pulled out in the longitudinal direction.

  On the other hand, the drawer 11 attached to the outlet 9 of the receiver 2 is formed by bending one steel plate as shown in FIG. It can be installed from below. The drawing tool 11 includes an abutting portion 12 on which the main reinforcing wire 3 extending in the longitudinal direction is placed and abutted, and a support portion 13 that supports the cable C drawn from the receiving device 2 from below. Further, in the drawing tool 11, a step portion 14 is formed between the contact portion 12 and the support portion 13 so that the contact portion side start end 13 a of the support portion 13 is higher than the contact portion 12. Further, a vertical piece 15 that is bent substantially vertically downward is integrally formed at the end of the contact portion 12 opposite to the support portion 13. Further, a detent projection piece 16 is extended on the same plane at the lower end central portion of the vertical piece 15. The drawer 11 is detachably attached to the drawer 9 of the receiver 2 using a fixing bracket 21 shown in FIG. Of course, the drawer 11 can be attached using a fixture other than the fixture 21.

  More specifically, the drawing tool 11 is first formed in the shape of a horizontal plate, and the portion near the vertical piece 15 is provided with a fixing hole 12a composed of a plurality of square holes at predetermined intervals. It has been. Similarly, the vertical piece 15 is provided with a fixing hole 15a composed of a plurality of square holes at a predetermined interval. These fixing holes 12a and 15a are through-holes for attaching and fixing the drawing tool 11 to the receiving tool 2 by inserting bolts used for the fixing fitting 21 into these parts and tightening the nuts. These fixing holes 12a and 15a are not limited to square holes.

  Here, the fixing fitting 21 is provided with a pair of parallel engaging recesses that fit into the wire, and a bolt insertion hole 22 through which a bolt is inserted is provided in an intermediate portion thereof. A round head square root bolt is used as the bolt. Although the round head square root bolt is not shown, the base of the bolt shaft is formed in a prismatic shape, and when the bolt shaft is inserted into the bolt insertion hole 22 and the fixing hole 12a of the extraction tool 11, the base of the bolt shaft becomes the bolt insertion hole 22. Mating. For this reason, at the time of attaching the drawing tool 11, the nut can be tightened with the round head square root bolt in a non-rotating state. Further, since the head of the bolt is a round head, the cable C is not damaged by contact on the contact portion 12 of the drawing tool 11. Any one of the pair of parallel engaging recesses can be arbitrarily selected and engaged with the wire.

  Next, the support part 13 is formed in the curved plate shape which made the upper side convex, and the cable C on the laying surface 8 of the receiving device 2 draws a gentle arc, and is pulled out below. The curvature of the support portion 13 is set so as to draw an optimal arc in consideration of the diameter, rigidity, etc. of the cable C. A bundling hole 13b composed of a plurality of square holes is provided at an end of the support part 13 on the side opposite to the abutting part. This bundling hole 13b is a through-hole for bundling the cable C by inserting a bundling band, a bundling string, etc. in order to prevent displacement and movement of the cable C drawn and placed on the support portion 13 and to keep it stably. It is.

The step portion 14 of the drawing tool 11 is formed so that the contact portion side start end 13a of the support portion 13 is higher than the planar position of the contact portion 12, and is formed in a straight shape in a direction perpendicular to the drawing direction of the cable C. Has been. The step, which is the vertical height of the step portion 14, is formed to have a length that is the same as or slightly smaller than the outer diameter of the main reinforcement wire 3, and at least the cable C is cut on the contact portion 12. It is formed in the level | step difference which does not contact the made edge part 3a. In addition, although the step part 14 is formed in the inclined surface in FIG. 3 etc., you may form in a perpendicular | vertical surface. Here, the level difference of the stepped portion 14 is slightly smaller than the outer diameter of the parent reinforcing wire 3. The level difference of the stepped portion 14 is required to have a rotation preventing function in the side drawer of the support 2 shown in FIG. From the property, it means that the length is at least half of the outer diameter of the wire extending in the longitudinal direction.

  Next, in order to attach the drawer 11 configured in this way to the outlet 9 of the receiver 2, the drawer 11 is brought close to the laying surface 8 of the outlet 9 of the receiver 2 from below, and the fixing bracket 21 is attached. The abutting portion 12 of the drawing tool 11 is used and fixed to the parent muscle wire 3 of the receiving tool 2. Specifically, although illustration of a bolt and a nut is omitted, after fitting any one of the engagement recesses of the fixing bracket 21 to the main reinforcement wire 3 from above, the bolt is inserted from above the bolt insertion hole 22 and the drawing tool. 11 is inserted into the fixing hole 12a of the abutting portion 12, and the nut is tightened from the back side of the abutting portion 12 of the drawing tool 11, that is, from below, and the bolts and nuts are used to tighten the parent reinforcing wire 3 and the drawing tool 11 The contact part 12 is clamped. Since the bolt head is round as described above after the drawer 11 is attached, the cable C will not be damaged by contact with the bolt head.

  When the drawing tool 11 is attached in this manner, the drawing portion of the cable C is placed on the support portion 13 of the drawing tool 11 and hangs downward. Accordingly, the cable C gently descends along the curved surface of the support portion 13 and is prevented from being broken due to a sharp bend in the lead-out portion. After the cable C is placed on the support portion 13, although not shown, a binding member such as a binding band or a binding string is inserted into the binding hole 13 b of the support portion 13 to fix the cable C on the support portion 13. In FIG. 1, in order to show the end portion 3 a of the main reinforcement wire 3, the cable C is illustrated at a position spaced apart from the main reinforcement wire 3 in the width direction. Of course, it is often pulled out.

Next, the operation of the drawer 11 will be described.
Since the pulling tool 11 has a stepped portion 14 formed between the contact portion 12 and the support portion 13, the end portion 3a of the parent muscle wire 3 positioned on the contact portion 12 is shown in FIGS. As shown in FIG. 4, the stepped portion 14 of the drawer 11 becomes a kind of wall surface and is covered with this. For this reason, since the cable C drawn out from the outlet 9 is prevented from coming into contact with the end portion 3 a of the main reinforcement wire 3, the cable C is surely prevented from being damaged by the end portion 3 a of the main reinforcement wire 3. The Here, it does not matter whether the end portion 3a of the parent reinforcing wire 3 is cut at the site or is formed by cutting in advance.

  Moreover, since the level | step difference which is the perpendicular | vertical height of the step part 14 is formed the same as the outer diameter of the main reinforcement wire 3, or slightly smaller, the contact part side start end 13a of the support part 13 which forms the step part 14 is By being too higher than the contact part 12, it can prevent that the front end surface of the cable C pulled out cannot be smoothly pulled out by the step part 14.

  By the way, in the said embodiment, although the drawing tool 11 showed what was attached to the edge part of the longitudinal direction of the receiving tool 2, the attachment location of the drawing tool 11 is not restricted to this. For example, as shown in FIG. 4, the two main reinforcement wires 3 are cut at a position adjacent to the welded portion with the child reinforcement wire 4 in the middle of the longitudinal direction of the support 2, and formed by this cutting. The drawer 11 can be attached to the outlet 9 in the same manner. In this case, the drawing tool 11 has a narrow width, and the cut end portion 3a of the main reinforcing wire 3 is covered with the stepped portion 14 of the support tool 11 and pulled out as in the case shown in FIG. The cable C is prevented from coming into contact with the end portion 3a of the parent reinforcing wire 3 and being damaged. Further, although not shown, the laying surface 8 of the receiver 2 is formed in two upper and lower stages, and may be attached to the end of the longitudinal direction of the laying surface 8 on the upper stage side or a place where the cable C is pulled out in the middle. it can. Alternatively, in the receiver 2 of the above embodiment, the bottom 6 is the laying surface 8 of the cable C, but the cable C is used in the so-called vertical receiver 2 that is installed vertically and the side 7 is the laying surface 8. It can also be attached to the place where it is pulled out. In the case of this vertical receiver 2, the side portion 7 corresponds to a “bottom portion” in the claims, and the bottom portion 6 corresponds to a “side portion” in the claims.

  In addition, in each of the above-described embodiments, the cable C is drawn out in the longitudinal direction of the receiver 2. However, the drawer 11 can be applied to the side of the receiver 2. FIG. 5 shows an embodiment in which the cable C is pulled out to the side of the support 2, and the support 2 is welded in the middle of one main reinforcement wire 3 and one child reinforcement 4 in the middle. The outlet 9 which is cut at a position adjacent to the portion and thereby opens to the side is formed. In this case, although the drawing tool 11 is not illustrated, the drawing tool 11 is attached and fixed to the receiving tool 2 by the fixing bracket 21 or the like using the fixing hole 12a of the contact portion 12, and the cable C is connected to the receiving tool 2 side from the outlet 9. Pulled out towards. Here, the step part 14 of this drawing tool 11 has a level | step difference for two wires which added the main reinforcement wire 3 and the child reinforcement wire 4 so that the edge part 4a of the cut child reinforcement wire 4 may be covered. As can be seen from this, the drawing tool 11 of the present invention is not limited to the step 14 having the same or slightly smaller step than the outer diameter of the main reinforcing wire 3 described above. The case shown in FIG. 5 corresponds to the embodiment of claim 2.

By the way, when the step portion 14 has a step that is the same as or slightly smaller than the outer diameter of the main reinforcing wire 3, the drawing tool 11 of the present invention is designed to pull out the cable C from the side of the receiving tool 2. It can also be attached to a portion around the side portion 7 that is the end of the width direction 2.
That is, in the drawing tool 11 shown in FIG. 6 (a), since the step portion 14 is formed at a level difference that is the same as or slightly smaller than the outer diameter of the main reinforcement wire 3, as shown in FIG. Since the contact portion side start end 13a of the portion 13 does not interfere with the bent portion 4b between the bottom portion 6 and the side portion 7 of the child reinforcing wire 4, it can be freely attached to the end portion in the width direction of the receiver 2 without any trouble. it can. In FIG. 6, the illustration of the cable C is omitted, and only the drawing direction of the cable C is indicated by a white arrow. The same applies to FIG. 7A described later.

In this case, the stepped portion 14 of the drawer 11 can be brought into contact with the main reinforcing wire 3 at the end in the width direction of the receiver 2 in a straight line along its longitudinal direction and locked. It also serves as a mating portion, and can be stably attached to a predetermined position of the receiving tool 2 by preventing the drawing tool 11 from rotating. In addition, although the drawer | drawing-out tool 11 is making the step part 14 contact | abut and latch along the longitudinal direction to the main reinforcement 3 of the width direction of the holder 2 along the longitudinal direction, the step part 14 of the holder 2 is attached. You may attach to the support 2 by making it contact | abut to the main reinforcement wire 3 of the width direction inside along a longitudinal direction, and latching .

  Next, as shown in FIG. 7, the drawer 11 can be attached to the deformed wire 5 of the receiver 2 and the cable C can be pulled out to the side of the receiver 2. As shown in FIG. 7 (a), the drawing tool 11 can be attached by using the fixing hole 15 a of the vertical piece 15 and attaching the fixing fitting 21 to the upright portion of the reinforcing bar 4. When the drawer 11 is attached, the cable C rises from the laying surface 8 of the receiver 2 and climbs over the contact portion 12 of the drawer 11 as shown in FIG. It pulls out in the direction and is placed on the support part 13 and hangs diagonally downward. It should be noted that, when the drawer 11 is attached, immediately before the fixing bracket 21 is attached, if the drawer 11 is not gripped by hand, the deformed wire 5 is caused by the load of the cable C placed on the support portion 13. The rotation-protruding protrusion 16 at the center of the lower end of the vertical piece 15 is the main reinforcing wire in the width direction of the holder 2. 3, the drawing tool 11 is prevented from rotating about the contact portion P with the deformed muscle wire 5 as an axis, and is temporarily held and prevented from falling. Thereby, the attaching operation | work of the drawer 11 can be performed smoothly.

By the way, although the drawing tool 11 of each said embodiment is attached to the receiving tool 2 using the fixing hole 12a of the contact part 12, or the fixing hole 15a of the vertical piece 15, you may attach by other means, These fixing holes are not necessarily required.
In addition, although the cable C is fixed on the support portion 13 by passing a binding member such as a binding band through the binding hole 13b of the support portion 13 of the drawer 11, the binding hole 13b is not necessarily required. The formation of can also be omitted.
Furthermore, although the drawer | drawing-out tool 11 is formed by bending a steel plate, it is not restricted to this, For example, you may form a sheet of a synthetic resin board.

In each of the above embodiments, in the receiving device 2, the parent muscle wire 3 is disposed on the lower side of the child muscle wire 4, but the parent muscle wire 3 is disposed on the upper side of the child muscle wire 4. It may be what was done.
Moreover, in each said embodiment, although the cable C is shown as wiring and piping material, it cannot be overemphasized that the drawer 11 of this invention is applicable similarly when using other wiring and piping material.
