2. Description of the Related Art For example, Japanese Patent Application Laid-Open No. 7-184309 discloses a technique for receiving a wiring and piping material of this type. 4 and 5 show a conventional receiving device for wiring and piping materials. A receiving device 1 includes a mounting portion 2 on which a cable C as a wiring and piping material is mounted, and a standing portion from both ends of the mounting portion 2. And the side portions 3 provided. This receiving device 1 connects a plurality of metal supporting wires 4 bent in a substantially U-shape with a bottom portion 5 forming a mounting portion 2 and a rising portion 6 forming both side portions 3 in a longitudinal direction. Are connected to each other by a metal connecting wire 7 and a holding wire 9 disposed on the upper end portion and the mounting portion 2, respectively, to form a vertical and horizontal mesh. The outer surface of the upper end of the rising portion 6 of the support wire 4 and the connection wire 7 are connected by welding at a fusion portion 8 where they intersect. Also, the lower surface of the bottom 5 of the support wire 4 and the holding wire 9 are similarly connected by welding.

[0003]

However, the above-mentioned conventional wire and pipe receiving device 1 is formed in a net shape by welding the supporting wire 4 to the connecting wire 7 and the holding wire 9. Since the supporting wire 4 and the connecting wire 7 are fused at the fusion portion 8, after welding, as shown in FIG. 6, the inner dimension L1 of both connecting wires 7 is equal to the amount of the left and right elution allowances a. It becomes smaller than the outer dimension L2 of the rising portion 6 of the support wire 4. As a result, in storage, transportation, etc.
One support 1 is displaced in the longitudinal direction, that is, in the installation direction, with respect to the support wire 4 of the other support 1 with respect to the support wire 4 of the other support 1.
Is stacked on another receiving device 1, since the outer surface of the rising portion 6 of the supporting wire 4 interferes with the inner surface of the connecting wire 7,
The support wire 4 of one receiver 1 cannot be fitted between the connecting wires 7 of the other receiver 1. Therefore, it is not possible to stack a large number of the receiving devices 1 vertically in multiple stages without creating a useless space, which increases the storage space and inconvenience in transportation.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wiring and piping material receiving member which can be stacked easily in multiple stages without wasteful space and which can enhance the transportation and storage efficiency. It is.

And a plurality of metal supporting wires 4 bent in a substantially U-shape with the rising portion 6 forming the upper portion 6 and the metal supporting wires 4 disposed on the upper end portion of the side portion 3 and the mounting portion 2 in the longitudinal direction. The connection wire 7 and the holding wire 9 are connected to form a vertical and horizontal mesh. The outer surface of the upper end of the rising portion 6 of the support wire 4 and the connection wire 7 are connected by welding at a fusion portion 8 where they intersect. Also, the lower surface of the bottom 5 of the support wire 4 and the holding wire 9 are similarly connected by welding.

[0007] The connecting wire 7 is flattened up and down, and at least a side surface in contact with the supporting wire 4 is formed flat. The flattening of the connecting wire 7 can be performed by crushing in the lateral direction by a known means. In addition,
The connecting wire 7 may have other shapes. However, if the flattening is performed, it is easy to weld, and a material having high strength can be obtained. Further, the connecting wire 7 is connected so as to protrude slightly upward from the upper end of the rising portion 6 of the supporting wire 4. However, the present invention is not necessarily limited to this, and does not prevent connection near the upper end of the rising portion 6.

The supporting wire 4 has an upper portion 6 having a stepped portion 6a which is bent in a stepped shape at an intermediate portion thereof, and a lower portion of the lower portion than the fusion portion 8 with the connecting wire 7 is an upper end portion. , Protrudes inside the receiving member 1 by the dimension of the step b. Further, in the fused portion 8 where the supporting wire 4 and the connecting wire 7 are welded, either due to the elution of both the supporting wire 4 and the connecting wire 7 or due to the difference in the material between the supporting wire 4 and the connecting wire 7. If only one of them is eluted, the elution of one of them results in the amount of support wire 4 corresponding to elution margin a.
The contact surface between the wire and the connecting wire 7 is recessed into the other member. Here, the dimensional difference between the step b, that is, the outer surface of the upper end portion of the rising portion 6 and the outer surface of the portion below the step portion 6a protruding inside the holder 1 is formed to be at least larger than the elution allowance a. Here, the step b corresponds to the bending dimension of the claims.

In FIG. 2, L1 indicates the inside dimension of the connecting wire 7 at the fusion joint 8, and L2 indicates the outside dimension of the rising portion 6 of the supporting wire 4. Here, between the inner dimension L1 of the connecting wire 7 and the outer dimension L2 of the rising portion 6, as described above, since b> a, a relationship of L1> L2 is always established.

Next, the operation of the receiving device of the present embodiment configured as described above will be described. In the receiving device 1 of the present embodiment, since the step portion 6a where b> a is formed, the relationship of L1> L2 is always satisfied, and the connecting wire 7 is provided on both side portions 3 of the receiving device 1 respectively. Only one is provided. For this reason, when storing and transporting, the receiving wires 1 are vertically stacked with the supporting wire 4 of one receiving device 1 shifted in the longitudinal direction, that is, the laying direction with respect to the supporting wire 4 of the other receiving device 1. In addition, the support wire 4 of one receiving tool 1 can be fitted between the connection wires 7 without being interfered with by the other connection wires 7. After the fitting, as shown in FIG. 3, the connecting wires 7 of each receiving device 1 may have a gap in the vertical direction, but at least the lower surface of the supporting wire 4 at the bottom 5 of each receiving device 1 The bottom of the other receiver 1 is securely brought into contact with the upper surface of the support wire 4. Therefore, since a large number of the receiving members 1 can be easily stacked vertically in multiple stages in a state where at least the bottom supporting wires 4 are in contact with each other, the receiving members 1 can be stored compactly and can be easily transported.

Further, since the connecting wire 7 is flattened and at least a side surface in contact with the connecting wire 7 is formed in a flat surface, even if the supporting wire 4 has a round bar shape, it can be easily welded to a predetermined position. As well as increase the welding strength.

Further, the connecting wire 7 is connected to the rising portion 6 of the supporting wire 4.
Is welded at a position projecting slightly upward from the upper end of the supporting wire 4 when the cable C is drawn into the installation path of the receiving device 1 from the side of the receiving device 1. Can be prevented from being damaged by welding with the upper end corners of the.
