And at least one of the fourth side nets, and each of these side nets is formed to have a rectangular basic shape by a rhombic wire net formed by sequentially linking column lines bent in a uniform flat spiral shape. And at least the bottom net and the first side net among the bottom net, the first side net, and the second side net are each configured to be adjustable in the widthwise direction, and at least one of these double-side nets The first side net is composed of two left and right net portions that are individually formed and can be connected to each other with their ends overlapping each other, and the above-mentioned size is adjusted by changing the degree of overlap between these two net portions. That is configured to Square Jakago is provided to symptoms.

[0006] The square gabion having the above-mentioned structure can be obtained by adjusting the dimensions of the bottom net and the first side net, or by adjusting the dimensions of the second side net, so that the trapezoidal gabion in the plan view and the overall width dimension can be obtained. A gabion or the like having a reduced size can be formed easily and quickly. For this reason, it is suitable when a plurality of gabions are connected in a curved shape and installed without gaps, or when a gabion smaller than the regular size must be partially installed in a narrow place, etc. Easy and excellent workability.

According to one specific embodiment of the present invention, each of the two net portions of the first side net is formed by stretching a diamond-shaped wire net on a rectangular frame line, and at least one of the net portions is formed. Has one or more connecting bone lines attached at an intermediate position of the mesh portion,
With this column line, both net portions can be connected in an overlapping state. It is preferable that the connection bone line is inserted into the spiral space of the row line and both ends are movably connected to the frame line, so that the position can be adjusted in the spiral space of the row line.

According to a preferred specific embodiment of the present invention, the size of the bottom net can be adjusted by loosening the connection between the column lines and increasing the degree of overlap between the adjacent column lines. For example, the linkage between the column lines in the bottom network is gradually loosened gradually from the second side connected to the second side network toward the first side connected to the first side network. The first according to the size of one side
By reducing the size of the side net, the gabion can be formed in a trapezoidal shape in plan view.

[0009]

1 and 2 show a preferred embodiment of a square gabion according to the present invention. The gabion 1A includes a bottom net 10, a pair of opposing first side nets 11 and second side nets 12, a pair of other opposing third side nets 13 and fourth side nets 14, and a top net 15. And is formed by connecting these surface nets in a hexahedral shape. As will be described below,
By reducing the size of the side on the first side net 11 side between the first side net 11 and the upper side net 15, the first side net 11 is formed in a trapezoidal shape in plan view by reducing the size of the first side net 11 in the width direction. .

Each of the screen nets 10 to 15 is individually formed by a rhombic wire net formed by sequentially linking column lines 17 bent in a uniform flat spiral shape, and has a uniform rectangular shape such as a rectangular shape or a square shape. It is formed as follows, and on the outer periphery of each screen net,
A frame 18 made of wire is formed on a ring formed at the end of each column line 17.
, The frame line 18 is attached in a rectangular shape. The direction of the column line 17 in each of these surface nets is such that the axis of each column line 17 is oriented in the vertical (up and down) direction in the side nets 11 to 14, and the column line 17 is in the bottom net 10 and the top net 15. Are oriented so as to point in the direction connecting the first side net 11 and the second side net 12.

The first side net 11 is divided into left and right two net portions 11a and 11b, and the first side net 11 is connected to each other by connecting these net portions 11a and 11b to each other. Is formed. Each of the above net portions 11
a and 11b are individually formed by stretching the above-mentioned rhombic wire netting on the rectangular frame line 18, and each width dimension a is about 1 of the width dimension b of the second side net 12. / 2, and these two net portions 11
The first side net 11 having substantially the same dimensions as the second side net 12 when the end sides of the first side net 11a and the first side net 11b are connected to each other by abutting each other.
Is formed, and when the ends are overlapped and connected as shown in FIG.
A side net 11 is formed. That is, the size of the first side net 11 can be adjusted by adjusting the degree of overlap between the ends of the two net portions 11a and 11b.

At least one bone line 21 for mutual connection is attached to at least one of the two net portions 11a and 11b at an intermediate position at an appropriate interval, and the bone line 21 and the other net portion 11b are provided. By connecting the frame line 18 at the tip of the wire with a wire or a spiral connection metal fitting,
The two net portions 11a and 11b can be firmly connected in a state where the dimensions are adjusted to a required length. In this case, it is desirable that the upper and lower frame lines 18 of both net portions 11a and 11b are also connected at appropriate positions. The bone line 21 is the column line 17
The two ends are movably connected to the upper and lower frame lines 18 in a state of being vertically inserted into the spiral space of the column line 17 so that the connection position can be adjusted in the spiral space of the row line 17. By adjusting the position of the bone line 21, the first
The size of the side net 11 can be finely adjusted.

When connecting the two net portions 11a and 11b to each other, as shown by a chain line in FIG.
The tip of 18 is extended straight, and its extension 18d,
18d may be connected to the upper and lower frame lines 18, 18 of the other net portion 11a. In this case, the extension 18d
Is preferably the same as the length of the portion that does not overlap when the other net portion 11a is connected, so that at least one continuous frame line 18 is provided on the upper and lower sides of the first side net 11 over its entire length. As a result, not only the connection strength between the net portions increases, but also the connection strength between the first side net 11 and the bottom net 10 and the top net 15 increases.

The dimensions of the bottom net 10 and the top net 15 in the width direction can be adjusted. The adjustment is
This is performed by loosening the linkage between the column lines to increase the degree of overlap between the adjacent column lines 17, and when the linkage is loosened evenly over the entire network, the dimensions of the entire network are reduced uniformly. However, in this embodiment, as shown in FIG. 3, the connection between the column lines in the bottom net 10 and the top net 15 is changed to the second side 10 to which the second side net 12 is connected.
By gradually loosening from the sides b and 15b toward the first sides 10a and 15a to which the first side net 11 is connected, only the dimensions of the first sides 10a and 15a are reduced, whereby 10 and the upper surface net 15 are formed in a trapezoidal shape.

As a preferred example of the method of adjusting the size of the screen net, as shown in FIG.
A frame line 18a for dimension adjustment is attached to each of the a and 15a so that the length thereof can be adjusted, and the ends of the respective column lines 17 are converged inward along the frame line 18a to thereby measure the size of the side. After reducing the size of the frame 18
There is a method of adjusting the length of a and then connecting and fixing both ends of the frame line 18a to the frame line 18 on the other side. in this case,
The frame line 18a for dimension adjustment is fixed to the fixed end 1 by locking one end thereof to the column line 17 at the side end or another frame line 18.
8b, and the other end is desirably extended outside the side as a non-fixed end 18c. Alternatively, such a fixed end 1
Frame lines 18a and 18 having a fixed end 8c and an unfixed end 18c.
a are mounted in opposite directions, and these frame lines 18
Each column line 17 can be tightened from both sides by pulling the non-fixed end 18c in both directions. It should be noted that the frame line 18a for dimension adjustment and the other normal frame line 18 are represented by a common symbol "18" except when they are distinguished and displayed.

Each of the screen nets 11 to 15 is transported to the site in a state where they are all separated from each other.
5 and the first side net 11 are adjusted in size.
1 and the side nets 11 to 14 are connected to form a gabion as shown in FIG. 1, and a filler such as rubble and earth and sand is filled therein, and then a top net 15 is attached or installed. As illustrated in FIG. 4, other screen nets 10 to 14 except for the upper screen net 15 are connected in advance in an expanded state, and are transported to the site to be assembled while adjusting the dimensions. In the latter case, it is possible to save the trouble of connecting the screens at the site as compared with the former.

The one shown in FIG. 4 has a second side net 12 on a second side 10b of the four sides of the bottom net 10, and a third side 10b.
The third side net 13 is provided on the side 10c, and the fourth side net 13 is provided on the fourth side 10d.
The side nets 14 are rotatably connected to each other.
On one short side 13a of the side net 13 is the first side net 11
Of one of the two net portions 11a and 11b constituting the short side 1 corresponding to that of the fourth side net 14.
The other net portion 11b is rotatably connected to 4a. The connection of each of these screens is performed by connecting
It is performed by suturing each other with a coil-shaped connecting wire 22, but what kind of connecting wire 22 is used is arbitrary. In addition, a frame line 18a for dimension adjustment is attached to the first side 10a of the bottom net 10 where the dimension is to be adjusted so that the length can be freely adjusted. Although not shown in FIG. 4, a frame 18a for dimension adjustment is similarly attached to the first side 15a of the upper surface net 15.

[0018] Such a network of connected nets is transported to the site in a state where it is folded to an appropriate size as required, and after it is unfolded at the site as shown in FIG. 4, as shown in FIG. The side nets 11 to 14 are erected and the sides of the adjacent side nets are connected to each other by a connection line 22, and the first side 10 a of the bottom net 10 is reduced by size adjustment, and two The first side nets 11 are formed by connecting the net portions 11a and 11b in a partially overlapping state, and these net portions 11a and 11b are connected to the first side 10a of the bottom net 10.
Are connected by a connection line 22. Also, the first side 1 of the upper surface net 15
5a is also reduced according to the first side 15a of the bottom net 10. Thus, a trapezoidal square gabion as shown in FIG. 1 is formed.

The gabions 1A thus formed are arranged side by side in a curved shape as shown in FIG. 5, and adjacent ones are connected as required. Thereby, the plurality of gabions 1A can be continuously provided in a curved shape without gaps. Moreover, only by reducing the dimension of a specific side at the construction site, it is possible to easily form a deformed shape having different dimensions at one end side and the other end side, so that the handling is easy.

The above-mentioned gabion can be stacked up and down in a plurality of stages. In this case, by omitting the top net 15 except for the top gabion, the bottom net 10 is connected between the upper gabion and the lower gabion. It is possible to eliminate waste that the upper surface net 15 and the upper surface net 15 are interposed twice.

Although the size of the gabion on the first side net 11 is reduced in the above example, it is needless to say that the size of the second side net 12 can be reduced by a similar configuration. is there.

In addition, at least one of the bottom net 10 and the top net 15 whose dimensions have been adjusted by loosening the linkage of the row lines 17, the loose row lines 17 are pushed outward by stuffing stones or the like and bulged outward. Or misalignment,
One or more reinforcing wires can be attached in at least one of a longitudinal or lateral direction or a diagonal direction. These reinforcing wires may be attached by sewing the mesh of the wire mesh, inserted by being inserted into the spiral space of the column wire 17, or inserted by being inserted into the engaging portion between the row wires 17, It may be attached to the front surface or the back surface, and the attachment method is not limited.

FIG. 6 shows a second embodiment of the square gabion of the present invention. The difference between the square gabion 1B of the second embodiment and the square gabion 1A of the first embodiment is that the first embodiment is different from the first embodiment. Then
By reducing only the size of the gabion on the first side net 11 side, the gabion is formed in a trapezoidal shape.
In the embodiment, the overall width of the gabion is reduced by reducing the size of both the first side net 11 and the second side net 12. In this case, the dimensions of the bottom net 10, the second side net 12, and the top net 15 (not shown) are reduced as a whole by loosening the connection between the column lines 17 almost uniformly over the entire net. ing.

The configuration of the second embodiment other than the above is substantially the same as that of the first embodiment.
The same reference numerals as in the embodiment are used and the description is omitted.

FIG. 7 shows a third embodiment of a square gabion according to the present invention. The difference between the square gabion 1C of the third embodiment and the square gabion 1B of the second embodiment is that the second side net is provided. 12 is formed by two net portions 12a and 12b as in the case of the first side net 11, and the size is adjusted by overlapping and connecting these net portions 12a and 12b.

Since the configuration of the third embodiment other than the above is substantially the same as that of the second embodiment, the same components as those of the second embodiment are denoted by the same reference numerals and the description thereof is omitted.

Since the gabions of the first to third embodiments have both the third side net 13 and the fourth side net 14, when they are arranged side by side as shown in FIG. The two side nets 13 and 14 will be interposed at the joining part of. Therefore, in order to eliminate such waste, one of the third side net 13 and the fourth side net 14 can be omitted.

In this case, when a plurality of meshes are to be transported to a site in a partially connected state in advance and assembled,
For example, as shown in FIG.
And the third side net 13 and the third side net 13
Are connected to each other by overlapping two net portions 11a and 11b forming the first side net 11 on the short side 13a. Then, as shown in FIG. 9, each of the side nets 12 and 13 of the above-mentioned net mesh connection body is erected, and two net portions 1 are formed.
After 1a and 11b are expanded in both the left and right directions and the size of the bottom net 10 is adjusted, adjacent gabions are connected to each other. At this time, the net portion 11 connected to one gabion
The first side net 11 is formed by connecting a and the net portion 11b connected to the other gabion in an overlapping state.

As the gabion connected to one end of the gabion row, a gabion in which only one net portion 11a is attached to the third side net 13 is used, and the end of the gabion connected to the other end is used. The part is a fourth side net 13 with a net portion 11b attached.
Is attached.

In each of the above embodiments, the bottom net 10 is
As in the case of the side net 11, the net may be divided into two net portions, and the dimension in the width direction may be adjusted by adjusting the degree of overlap. In this case, by gradually increasing the degree of overlap between the two net portions from the second side 10b side to the first side 10a side, the bottom net can be formed in a trapezoidal shape, and both net portions are evenly overlapped. This allows the overall width dimension to be adjusted.
