2. Description of the Related Art For example, a square gabion (futon cage) as shown in FIG. 8 is used for earth retaining work, revetment construction, river bottom conservation construction, etc. on sloping ground. This gabion is assembled in a cage shape by connecting a plurality of wire meshes 1a, 1b, 1c, ... Having a predetermined shape and size, and a wire is spirally wound to connect each wire mesh. The formed connecting line 2 is used, and by this connecting line 2, the row lines 3 and 3 of the adjacent wire meshes are used.
The bone lines 4, 4 inserted through the rings or the meshes of the ends of the column lines are connected to each other.

However, the conventional connecting wire 2 has a very small spiral pitch (hence a large number of turns), and when connecting wire mesh using this, the connecting wire 2
While gradually applying a force in the circumferential direction to the shaft while rotating it around the central axis, the screw is gradually advanced along the spiral, and it is sequentially inserted into the mesh of the adjacent wire mesh and locked to the row lines 3 and 3.
The wire nets are connected by being wound around the adjacent bone lines 4 and 4. Therefore, the plurality of connecting lines as a whole must be rotated by a very large number before the connecting work is completed for each ridgeline of the gabion, which is a troublesome and time-consuming operation.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a spiral connecting wire which can be connected without applying a force in the circumferential direction and rotating it around the central axis.

[0005]

In order to solve the above-mentioned problems, the connecting wire of the present invention is formed in a spiral shape with a wire, and the lead angle of the spiral is applied to the end of the connecting portion of the wire mesh. When it is pushed in the axial direction, the size is such that it can advance along the spiral while rotating around the axis itself.

[0007]

The tip of the connecting wire is applied to the end of the connecting portion with which the wire net to be connected is in contact, and the rear end of the connecting wire is pushed in the axial direction to be pushed along the connecting portion. Then, the connecting line advances along the spiral while rotating itself around the central axis and is inserted into the meshes of both wire meshes and locked to the row line, or
Alternatively, the wire mesh is wrapped around the bone wire, and the two wire nets are connected by this.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The connecting wire 10 of the first embodiment shown in FIGS. 1 and 2 has a rigidity sufficient to maintain the connected state. Is formed by spirally winding the wire, and the lead angle θ of the spiral, that is, the tangent line 11 of the spiral is a plane 1 perpendicular to the central axis 12.
The connecting portion 17 where the wire mesh to be connected is in contact with the angle θ formed by 3
When the tip end of the connecting wire 10 is applied to the end portion (see FIG. 4) and the connecting wire 10 is pushed in the direction of the central axis 12, the connecting wire 10 rotates around the central axis 12 by itself and follows the spiral. The size is set so that it can move forward.
The size of the lead angle θ that meets such conditions is 45 degrees or more and less than 90 degrees, but if the angle is small, the resistance at the time of pushing becomes large and the workability is poor, and conversely, if the angle is large, There is a problem that the number of turns decreases due to the large pitch of the spiral and the connection strength decreases. Therefore, the preferable range of the pitch angle θ is 60 to 88 degrees, and the more preferable range is 70 to 85 degrees. The spiral winding direction may be opposite to that shown, and the spiral winding diameter D
Is appropriately determined according to the thickness and the number of filaments to be wound therein.

When a plurality of wire nets 15 and 16 are connected to each other by the connecting wire 10 having the above structure, as shown in FIG. 4, the connecting wire 10 is connected to the central axis 12 with respect to the connecting portion 17 where both wire nets are in contact with each other. Are arranged so that they are parallel to each other, and the tip thereof is applied to the end of the connecting portion 17 so that one or two peaks are wound around the bone wires 18 and 19, and the rear end of the connecting wire 10 is Push in the direction of the central axis 12
So that it is pushed in along. Then, the connecting line 10
As shown in FIG. 5, while advancing along the spiral while rotating itself around the central axis 12, the bone lines 18 and 19 attached to the ends of the row lines 20 and 21 of both wire nets 15 and 16 are attached. The wire nets 15 and 16 are wound so as to surround the wire nets, and the wire nets 15 and 16 are connected to each other.

Here, when the connecting wire 10 is pushed in along the connecting portion 17, the tip of the connecting wire 10 has bone lines 18, 1.
If the forward movement is impeded by hitting 9 or the column lines 20, 21, etc., the elastic force of the connecting wire 10 is used to push the tip while appropriately deflecting the tip of the connecting wire 1.
0 can be easily advanced. Also, the connecting line 10
By forming the pitch of the spiral in (1) to be an integral multiple or a fraction of the interval of the meshes of the wire nets 15 and 16, the work of pushing the connecting wire 10 can be performed more smoothly.

When the connecting portion 17 of the wire mesh is long, a plurality of connecting wires 10 having a shorter length than the connecting portion 17 are used, and these connecting wires 10 are wound around the connecting portion 17 one by one so that they are connected to each other. May be connected.

The connecting wire 10 thus attached prevents the connecting wire 10 from moving and falling off, or losing the connecting function due to the collapse of the spiral shape due to the external force acting on the wire mesh.
The ends 2 and 21 and the bone line 1 are bent by means such as bending.
It is desirable that the connecting wires 10 and 8 be locked to each other or be connected to another connecting wire 10, and in order to facilitate the work of preventing the connecting wire 10 from being pulled out, the rear end portion of the connecting wire 10 is indicated by a chain line in FIG. It is possible to preliminarily form a bent portion 22 that is bent into a U-shape or another shape. By forming such a bent portion 22, the connecting line 10 is connected as described above. When pushing into the portion 17, the cut end of the wire end is prevented from touching the hand, and the work can be safely carried out.

In the case of assembling a square gabion as shown in FIG. 8, the connecting line 1 is connected to each ridge line that needs to be connected.
The adjacent wire nets are connected to each other by 0, and the ends of the respective connecting wires are connected to the connecting wires attached to the row lines, the bone wires, and the other ridgelines of the wire nets as necessary.

The connecting line 10 has rings 20a and 21a at the ends of the column lines 20 and 21, as shown in FIGS.
It is not used only when connecting the bone wires 18 and 19 inserted through the wire, as shown in FIG.
When the 16 column lines 20 and 21 are directly connected,
As shown in FIG. 7, when the column wire 20 of one wire mesh 15 and the bone wire 19 attached to the column wire 21 of the other wire mesh 16 are connected to each other, regardless of the presence or absence of the bone wire and the type and shape of the wire mesh. Can be used for interlocking any wire mesh.

Further, the connecting wire 10 is used not only when assembling the gabion but also when assembling the assembled gabions with each other, or other than the gabion, such as fences, lock nets, etc. Needless to say, it can also be used for connecting wire nets such as those described above, or for connecting wire nets and wire ropes.

FIG. 3 shows a second embodiment of the present invention.
The connecting wire 30 formed in the same manner as in FIG. 1 is provided with an inclined portion 31 that inclines toward the outer side of the spiral.
The inclined portion 31 prevents the tip of the connecting line 10 from abutting against the bone line, the row line, or the like when the connecting line 10 advances while rotating around the connecting line 10 by itself, and the advance of the connecting line 10 is prevented. It is very effective for smoothing. In particular, this is effective when the connecting wire 10 having a small winding diameter is used and wound around the bone wire with a small gap. In this case, the angle α with which the inclined portion 31 is inclined with respect to the spiral is preferably 45 degrees or less.

The connecting wires 10 and 30 are not limited to those wound along a cylindrical surface as shown in FIG. 2, but may be wound along an elliptic cylindrical surface, and their cross-sectional shapes are also possible. It is optional.

[0018]

According to the connecting wire of the present invention having the above-mentioned structure, it is possible to easily wind the connecting wire by simply rotating the wire itself by applying the tip of the connecting wire to the connecting portion of the wire mesh and pushing it in the axial direction. Therefore, it is not necessary to apply a force in the circumferential direction to rotate, and the connecting work can be performed easily and quickly.
