In this embodiment, at least the bottom and the opening of the mesh bag 21 are provided with a reinforcing band 22 extending over the entire circumference, and the inside is filled with a heavy material (not shown) such as a stone or a concrete lump. The mesh bags 21 are aligned in the length direction or the width direction, and a plurality of tension members 23 are overlapped with at least the reinforcing band 22 provided at the bottom and the opening of the mesh bags 21. Are arranged, and these tension members 23 and at least the reinforcing band 22 provided at the bottom and the opening are connected by a connecting member 24, so that the plurality of mesh bags 21 are integrated. I have.
[0010]
To explain these details, the tension member 23 is made of a metal wire, a synthetic resin wire constituting the mesh bag 21, or the like, and preferably a metal wire is used.
[0011]
The connecting member 24 is attached to the tension member 23 so as to be fixable and to be movable in the length direction of the tension member 23.
More specifically, as shown in FIGS. 3 and 4, these connecting members 24 are connected to a substantially U-shaped engaging member 25 disposed so as to surround the reinforcing band 22. A clamp member 26 is provided so as to be bridged between both ends of the member 25 and is fixed to the tension member 23 by sandwiching the tension member 23.
[0012]
The clamp member 26 is movably attached to two sets of lock nuts 27 screwed to each end of the engagement member 25, and movably attached to both ends of the engagement member 25. The tension member 23 is inserted between the clamp plates 28, and the tension members 23 are mutually connected by the two sets of lock nuts 27. By tightening in the approaching direction, the tension member 23 is sandwiched between the two clamp plates 28.

[0013]
In order to manufacture the mesh bag 21, as shown in FIG. 5 (a), a reinforcing band 22 is attached to the bottom and the opening of the mesh bag 21 and the opening is turned upward. As shown in FIG. 1), the mesh bag 21 is inserted into a bottomed cylindrical form C. Then, the mesh bag 21 is filled with a heavy material such as a stone or a concrete lump through an opening thereof to open the mesh bag 21. After binding the parts, the mesh bag 21 is pulled out from the mold C as shown in FIG.
[0014]
Then, the net-like bag 21 manufactured as described above is laid down in the horizontal direction as shown in FIG. 6B, and then, for example, as shown in FIG. Can be
[0015]
In this state, the tension member 23, to which the connecting member 24 is attached, is moved along the longitudinal direction along a plurality of locations spaced in the circumferential direction of the mesh bag 21 on the surface of the adjacent mesh bag 21 in the length direction. At the same time, an engaging member 25 constituting the connecting member 24 is attached so as to surround the reinforcing band 22, and the engaging member 25 is fixed to the tension member 23 by the clamp plate 28 and the lock nut 27. I do.
Thereby, a plurality of the plurality of net-like bags 21 are integrated, and the futon basket 20 according to the present embodiment is obtained.
[0016]
In the futon basket 20 obtained in this manner, the horizontal linear body 21b is knitted substantially orthogonally to the vertical linear body 21a when each mesh bag 21 is manufactured. The distance between each vertical linear body 21a and each horizontal linear body 21b is kept substantially constant.
That is, the stitches formed by the vertical linear bodies 21a and the horizontal linear bodies 21b are held in a rectangular shape.
As a result, the mesh body 21 formed by the vertical linear bodies 21a and the horizontal linear bodies 21b is held substantially in a cylindrical shape, and as a result, the installation density of the formed futon basket 20 is increased.
Further, in the present embodiment, by integrating the plurality of net-like bags 21, the weight as a whole is secured, and a drag against the flow of water is generated.
Further, by the action of the reinforcing band 22 provided at the bottom and the opening, the outer shape of each net-like bag 21 is restrained in a substantially columnar shape, and the installation density can be easily increased.
On the other hand, since the reinforcing bands 22 located at the ends of the adjacent net-like bags 21 are connected to each other, a sufficient connection strength between them is ensured, and there is no possibility that the net-like bags 21 are separated from each other. The weight gain function is not impaired.
[0017]
In particular, in the present embodiment, since the position of the connecting member 24 can be adjusted with respect to the tension member 23, for example, even if the shape of the mesh bag 21 is slightly deformed, the shape is adjusted according to the amount of deformation. Since the connecting member 24 can be located at the position, the connection of the mesh bag 21 can be easily and reliably connected.
[0018]
Note that the shapes, dimensions, and the like of each constituent member shown in the above-described embodiment are merely examples, and can be variously changed based on design requirements and the like.
For example, in the above-described embodiment, an example has been described in which the reinforcing band 22 is disposed at the bottom and the opening of the mesh bag 21. However, the reinforcing band 22 is also provided at an intermediate portion in the longitudinal direction of the mesh bag 21. It is also possible to provide.
With such a configuration, a change in the outer shape of the mesh bag 21 can be further suppressed.
By connecting the reinforcing band 22 provided at the intermediate portion to the tension member 23 via the connecting member 24, the connection between the mesh bags 21 can be further strengthened.
Further, as shown in FIG. 9, a swinging piece 29 is attached in the middle of the engaging member 25, and the swinging piece 29 is attached so as to be rotatable toward the inside of the engaging member 25. When the piece 29 rotates outward, engagement with the engagement member 25 restrains the outward rotation. Further, between the swinging piece 29 and the engagement member 25, It is also possible to adopt a configuration in which the swinging piece 29 is interposed with a return spring 30 that holds the swinging piece 29 at an engagement position with the engagement member 25.
With this configuration, when the engaging member 25 is attached to the reinforcing band 22, the reinforcing band 22 is brought into contact with the rocking piece 29, and the rocking piece 29 is rotated inward. By releasing the contact with the rocking piece 29 after the 22 is pulled into the engagement member 25, the rocking piece 29 is returned to the engagement position with the engagement member 25 by the return spring 30. By such a simple operation, the connection between the engagement member 25 and the reinforcing band 22 can be performed.
[0019]
On the other hand, as shown in FIG. 10, a bottom tie rope 21c is attached to the lower part of the mesh bag 21, and a mouth tie rope 21d is attached to the lower part. The mesh bag 21 may be formed in a bottomed cylindrical shape by performing bottom binding so that
The method of attaching the bottom tie rope 21c and the mouth tie rope 21d is not particularly limited, but it is necessary that the attachment method be such that the bottom tie rope 21c and the mouth tie rope 21d do not easily come off from the mesh bag 21.
[0020]
【The invention's effect】
As described above, according to the futon basket for civil engineering work according to the present invention, since the horizontal linear members constituting each net-like bag are woven substantially orthogonally to the vertical linear members, the inside is massive. When the heavy objects are packed, the stitches formed by the vertical linear bodies and the horizontal linear bodies can be held in a rectangular shape.
As a result, even in a state in which a massive load is filled, the mesh body can be held substantially in a cylindrical shape, and the installation density of the futon basket can be increased.
In addition, by integrating a plurality of net-like bags, the weight as a whole can be secured, and the drag against the flow of water can be greatly improved.
In addition, by mutually connecting the reinforcing bands located at the ends of the adjacent mesh bags, a sufficient connection strength between them can be ensured, the mesh bags can be prevented from detaching, and the weight increasing function can be performed for a long time. Can be secured.
Furthermore, the outer shape of each net-like bag is constrained in a substantially columnar shape by the reinforcing band provided at the bottom and the opening, whereby the installation density can be easily increased.
In particular, by making the position of the connecting member adjustable with respect to the tension member, for example, even if the shape of the mesh bag is slightly deformed, the connecting member can be positioned at a position corresponding to the amount of deformation. Therefore, the mesh bags can be easily and reliably connected.
