Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a square gabion used in revetment work, residential land construction work and the like, and a packaging method thereof.

[0002]

2. Description of the Related Art For example, as shown in FIG. 9, generally, a square gabion used for revetment work, residential land construction work and the like has a plurality of wire mesh panels 1a, 1b, 1c, 1 made of diamond wire mesh.
It is formed by d, 1e, and 1f, and is assembled into a rectangular parallelepiped by connecting these wire mesh panels to each other. When the gabion is transported to the installation site, the wire mesh panels 1a to 1f are unfolded and packaged in a state where they are superposed on each other, and are transported to the site for assembly.

However, as shown in detail in FIGS. 10 to 12, in the diamond-shaped wire net constituting the wire net panel 1, the column lines 2 and 2 wound in a flat spiral shape are sequentially connected at the bent portion 2a. Therefore, the thickness t of the wire mesh is considerably large. Moreover, when a plurality of wire mesh panels 1 and 1 are polymerized and packed as shown in the drawing, the line portion 2b below the spiral of the column line 2 in the upper wire mesh panel 1 is formed.
Of the wire mesh panel 1 in the lower row, but is contacted on the upper line portion 2c of the spiral of the column wire 2 to be polymerized, so that the total thickness T of the polymer is naturally the thickness of each wire mesh panel 1, 1. t
It will be the sum of Sa. Therefore, when a large number of wire mesh panels, such as several or dozens, are polymerized, the bulkiness becomes very large, and there is a drawback that transport efficiency is poor.

[0004]

SUMMARY OF THE INVENTION The technical problem of the present invention is to provide a rectangular gauze convenient for packaging, in which the thickness of a metal mesh panel when polymerized is less than the total thickness of the individual metal mesh panels. And a method of packaging the same.

[0005]

In order to solve the above-mentioned problems, a square gabion of the present invention is a square gabion consisting of a plurality of wire mesh panels, wherein each wire mesh panel is wound in a flat spiral shape. A part of the wire mesh panel is formed by a diamond wire mesh formed by connecting column lines in sequence, and a part of the wire mesh panel is formed by a standard mesh diamond wire mesh in which the spiral winding direction in the column line is the positive direction, and the remaining wire mesh. It is characterized in that the panel is formed by a rhombic wire mesh having a reverse mesh in which the spiral winding direction in the column line is the reverse direction.

In addition, the method for packaging a square gabion of the present invention is such that a square gabion consisting of a standard mesh wire mesh panel and a reverse mesh wire mesh panel as described above is packaged by unfolding and polymerizing the wire mesh panel. The standard mesh wire mesh panel and the reverse mesh wire mesh panel are polymerized with each other.

Thus, according to the present invention, the wire mesh panel of the standard mesh and the wire mesh panel of the reverse mesh are overlapped with each other, so that the spirally wound column lines constituting the wire mesh panels are reversed. The spiral-shaped column wire wound in the direction fits into each other between the spirals, and the lower line portion of the spiral of the column wire in the upper wire mesh panel and the line wire of the lower wire mesh panel The line portion on the lower side of the helix abuts, and the line portion on the upper side of the spiral of the column wire in the upper wire mesh panel and the line portion on the upper side of the helix of the column wire in the lower wire mesh panel abut. Therefore, the upper and lower wire netting panels are overlapped with each other with a slight height difference corresponding to the wire diameter of the column line, and as a result, the total thickness of the polymer can be made equal to or less than the total thickness of the individual wire netting panels.

[0008]

1 and 2 show an embodiment of a rectangular gabion according to the present invention. This gabion has a bottom wire mesh panel 11a, a front wire mesh panel 11b and a rear wire mesh panel 11c, and left and right side wire mesh panels 11d and 1
1e and an upper surface metal mesh panel 11f, each of these metal mesh panels 11a to 11f is individually configured by rhombic metal meshes having different shapes, and they are assembled into a rectangular parallelepiped by connecting them. There is. In the following description, each wire mesh panel 1 will be described.
Unless it is necessary to individually represent 1a to 11f, they are represented by a common reference numeral 11.

As shown in FIGS. 3 (A) to (C) and FIGS. 4 (A) to (C), the diamond-shaped wire mesh forming each wire mesh panel 11 has a plurality of column lines wound in a flat spiral shape. 13A or 1
It is formed by sequentially connecting 3B in the bent portion 13a. Of these, the diamond wire mesh 12A shown in FIG.
Is a diamond mesh of a standard mesh in which the spiral winding direction on the column line 13A is right-handed (forward direction). In the diamond-shaped wire net 12B shown in FIG. 4, the spiral winding direction on the column line 13B is left-handed (reverse). Direction) is a diamond mesh of reverse mesh.

Then, one of the pair of wire mesh panels at the opposite positions of the gabion is formed by the diamond mesh 12A of the standard mesh and the other is the diamond mesh 12 of the reverse mesh.
It is formed by B. That is, the bottom wire mesh panel 11a
And any one of the upper surface wire mesh panel 11f, one of the front surface wire mesh panel 11b and the rear surface wire mesh panel 11c, and one of the left and right side surface wire mesh panels 11d and 11e. Rhombus wire mesh 12A
And the other is formed by the diamond mesh 12B of the reverse mesh.

Each of the wire mesh panels 11a to 11f is provided with a frame line 15 made of wire on four sides of the outer circumference, and the frame lines 15 and 15 of the adjacent wire mesh panels 11 and 11 are connected to each other by a coil-shaped connecting fitting or the like. Although they can be assembled by connecting them to each other, the form of the wire mesh panel 11 and the connecting method thereof are not limited to this. For example, the adjacent side edges of adjacent wire mesh panels 11 and 11 are connected to each other by inserting a common bone line into a bent portion of a column line located on each side, or adjacent wire mesh panels. 1
It is also possible to connect the mutually adjacent end sides of 1 and 11 by inserting a common bone line into a ring formed at the end of the column line.

The square gabion having the above structure is shown in FIG.
Each wire mesh panel 1 is expanded as shown in Fig.
1 is packaged in the state of being polymerized with each other, and it is transported to the installation site. Then, as shown in FIG. 1, in the field, the bottom wire mesh panel 11a, the front wire mesh panel 11b, the rear wire mesh panel 11c, and the left and right side wire mesh panels 11d and 11e are assembled into a container shape and placed at a predetermined place. After that, they are filled with gravel and the like, and the upper surface wire netting panel 11f is attached to install.

5 to 7 when the wire mesh panels are superposed on each other and packaged in the transportation of the gabion.
As shown in, the bottom mesh screen panel 11a, the top mesh screen panel 11f and the front mesh screen panel 11f are arranged so that the metal mesh panel 11A composed of the standard mesh diamond mesh 12A and the mesh mesh panel 11B composed of the reverse mesh diamond mesh 12B are alternately overlapped.
b, the rear wire mesh panel 11c, and the left and right side wire mesh panels 11d are sequentially polymerized and packaged.

5 to 7 show, as an example, a case where two wire mesh panels 11A and 11B having a standard mesh and a reverse mesh are superposed. As is clear from these figures, when the standard mesh wire mesh panel 11A and the reverse mesh wire mesh panel 11B are polymerized with each other, those wire mesh panels 11A, 11
The column line 13A of the forward-direction spiral and the column line 13B of the reverse-direction spiral forming B are fitted into the spirals by falling in between each other and the column line 13 in the upper wire mesh panel 11A.
The lower line portion 13b of the spiral of A and the lower wire mesh panel 1
The lower line portion 13b of the spiral of the column line 13B in 1B abuts each other, and the upper line portion 13c of the spiral of the column line 13A in the upper wire mesh panel 11A and the line line 13B of the lower wire mesh panel 11B. Similarly, the line portion 13c on the upper side of the spiral abuts. For this reason,
As can be seen from FIG. 7, the upper and lower wire mesh panels 11A and 11B are overlapped with each other with a slight height difference substantially corresponding to the diameter of the column line, and the thickness T as a polymer is one wire mesh panel 1
Compared with the thickness t of 1A or 11B, only the line diameter of the column line is substantially different. As a result, the thickness of the polymer can be made much smaller than the total thickness of the individual wire mesh panels 11A and 11B.

When three or more standard mesh and reverse mesh wire mesh panels are to be polymerized, the wire mesh panels 11A and 11B having different mesh shapes try to occupy the above-mentioned positional relationship, but every other sheet. Since the wire mesh panels 11A and 11A or 11B and 11B having the same mesh shape located in each other interfere with each other, it is difficult to polymerize the wire mesh panels 11A and 11B with a small thickness as in the case of polymerizing the two metal mesh panels 11A and 11B. However, since the total thickness of the polymer is definitely smaller than the total thickness of the individual wire mesh panels 11, the bulkiness of the wire mesh panels 11 is increased when a large number of wire mesh panels 11, such as several or several tens, are polymerized. Can be made very small, mass transportation is possible, and transportation efficiency can be improved.

In the above description, the bottom wire mesh panel 11 is used.
a and the top wire mesh panel 11f, the front wire mesh panel 11b and the rear wire mesh panel 11c, and the left and right side wire mesh panels 11
Although d and 11e are sequentially polymerized, it is not always necessary to polymerize in such an order. The point is that if the standard mesh wire mesh panel 11A and the reverse mesh wire mesh panel 11B are alternately polymerized. It's good.

Further, it is not necessary to form all the pair of wire mesh panels at the opposite positions in such a normal mesh relationship, and a part of the plurality of wire mesh panels forming the gabion is a standard mesh wire mesh panel. 11A, and the rest is formed by the reverse mesh wire mesh panel 11B, and it is sufficient that they are polymerized with each other at the time of packaging, so that the gabion has only the standard mesh wire mesh panel 11A or the reverse mesh wire. Compared with the case where only the wire mesh panel 11B is formed,
It is possible to surely reduce the thickness of the wire mesh panel 11 at the time of polymerization.

Further, the gabion of the illustrated embodiment has eight wire mesh panels 11a to 11f, but the form of the gabion is not limited to this. For example, one or more partition nets for partitioning the inside into a plurality of stone-filled regions may be provided, and the top wire net panel 11f may be omitted depending on the installation conditions. Alternatively, in the case where the gabion is connected to the front and back and left and right to be installed, in order to eliminate the waste of a plurality of wire mesh panels 11 interposed between the joint surfaces of the adjacent gabions,
For example, as shown in FIG. 8, a gabion provided with a bottom surface gauze panel 11a, a front surface gauze panel 11b and one side surface gauze panel 11d is used, but the present invention can also be applied to such a modified gabion. . In this case, it is desirable that the front wire mesh panel 11b and the side wire mesh panel 11d are formed of standard mesh and reverse mesh wire mesh panels, but they are both formed of standard mesh or reverse mesh wire mesh panels, and the bottom metal mesh panel is formed. The panel 11a may be formed of a reverse mesh or standard mesh wire mesh panel.

[0019]

As described in detail above, according to the present invention,
Part of the multiple wire mesh panels that make up the gabion is formed by a standard mesh diamond wire mesh where the spiral winding direction in the row line is the positive direction, and the remaining wire mesh panels are in the reverse winding direction in the row line. Since it is formed by the reverse mesh rhombic wire mesh, the thickness when the wire mesh panels are polymerized when the gabion is developed and transported can be made equal to or less than the total thickness of the individual wire mesh panels.
