Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wire connecting jig.

[0002]

[Prior Art]

 When forming a box body by connecting wire mesh plates formed of vertical and horizontal steel wires, it is necessary to connect the steel wires of the wire mesh plates. BACKGROUND ART Conventionally, when connecting wire materials such as steel wires, various methods such as welding, bundling, use of C-type fixing metal fittings, use of hinges, use of coils, etc. have been used.

[0003]

[Problems to be solved by the device]

 The conventional connection technology of wire rods has the following problems. <a> The welding method requires workers with special skills and welding machines, is costly, labor-intensive, and cannot be easily disassembled. <B> As a binding method, a binding wire made of the same material as the wire is used, but the strength is insufficient, the binding work is troublesome, and the cut end of the binding wire is sharp and dangerous. <C> C-type fixing brackets are generally called C-rings or Heartco clips, and require workers and machines with special skills similar to welding, which is expensive and labor-intensive. , I cannot easily dismantle it. <D> Hinges can be connected so that they can be bent, and are convenient for assembly. However, when fixing them, additional complicated work such as welding and screwing is required. <E> In the case of a coil, it is easier than the above four methods, but the shape is not fixed firmly and is unstable, and it is difficult to use it when assembling a wire mesh plate into a box shape.

[0004]

[Means for Solving the Problems]

 The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a wire rod connecting jig that can be connected and disassembled easily and quickly and at low cost. That is, the present invention is a jig for connecting a plurality of wire rods arranged in parallel with each other, and has a plurality of arch-shaped holding surfaces each having a diameter approximately equal to the longest dimension of the wire rod cross section, and each holding surface has an axis line. Parallel to each other, a part of each holding surface is opened over the entire length in the axial direction, and the width of this opening is formed to be slightly smaller than the longest dimension of the cross section of the wire. It is a connecting jig.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a plurality of arch-shaped holding surfaces 11 having a diameter substantially equal to the longest dimension of a wire rod cross section are formed on an elastic chip 1 such as hard resin such as plastic, metal, wood, rubber or the like. .. FIG. 1 shows a case where the holding surfaces 11 are formed at two locations, and each holding surface 11 is configured such that the axes thereof are parallel to each other. In addition, a part of each holding surface 11 is opened over the entire length in the axial direction, and the width of the open portion 12 is formed to be slightly smaller than the longest dimension of the wire rod cross section. 2 and 3 are diagrams showing an example of dimensions of each part. The diameter A of the holding surface 11 is formed to be substantially equal to the longest dimension of the wire rod cross section as described above. Since the wire rods to be connected have various sectional shapes such as a circular shape, a rectangular shape, and an elliptical shape, they are formed so as to have a length approximately equal to the longest dimension of the cross section so that they can be stored and held in the holding surface 11. The width B of the release portion 12 is, for example, 5 to 25% smaller than the diameter of the wire rod so that the wire rod can be easily fitted and can be removed with some force. Further, the dimension C between the open portions 12 is 20% or more of the wire diameter, the depth D of the holding surface 11 is 60% or more of the wire diameter, and the thickness of the chip 1 shown in FIG. 1 is 30% or more of the wire diameter. The structure is such that the holding power of the material does not decrease and the ease of attachment / detachment can be secured.

[0006]

[Connecting method]

 Next, a method of connecting the wire rods will be described. In this embodiment, the case where the frame wire 21 of the wire mesh plate 2 as shown in FIG. 5 is connected will be described, but it goes without saying that other wire rods can be connected. First, as shown in FIGS. 3 and 4, the frame lines 21 of the wire mesh plate 2 are arranged in parallel. Then, the two open portions 12 of the chip 1 are pressed against the two frame lines 21 and fitted. Thereby, the two frame lines 21 can be easily connected. When the frame line 21 is disassembled, the chip 1 can be easily disassembled by pulling out the chip 1 in the direction opposite to that at the time of connection. There may be a case where only one chip 1 is used for connection, a case where the chips 1 are attached from both sides of the frame line 21 as shown in FIG. 3, or a case where three or more chips are attached.

[0007]

Second Embodiment In addition to the above embodiment, as shown in FIG. 6, parallel portions 13 having the same dimensions as the open portion 12 may be provided on both sides of the open portion 12.

[0008]

Third Embodiment Further, without using the chip 1, a band plate having elasticity such as hard resin such as plastic, metal, wood, rubber, etc. is bent to form the connecting jig 3, and the above-mentioned embodiment is carried out. In some cases, the holding surface 31 and the opening 32 having the same function as the above may be formed.

[0009]

Fourth Embodiment Further, as shown in FIGS. 8 and 9, connecting jigs 4 and 5 having three or more holding surfaces 41 and 51 and open portions 42 and 52 may be formed.

[0010]

[Effect of the present invention]

 Since the present invention is as described above, the following effects can be obtained. <A> The connecting jig of the present invention can be easily and quickly connected and disassembled by simply attaching / detaching it to / from the wire without using any other machine. Therefore, labor and construction time can be reduced.

<B> The manufacturing cost can be reduced because the structure is simple and the arch-shaped holding surface is formed of plastic or the like.

<C> Since the wire rod can be securely held and fixed by the holding surface, it can be used even when the box body is made of a wire mesh plate.
