In the structure of the futon basket, the side surface requires relatively strong rigidity to resist the earth pressure and the internal pressure due to the filling material, while the bottom part is supported by the ground or the bottom padding of the futon basket. Therefore, it does not require as much rigidity as the side surface.
Therefore, in the main body panel 10 of the present invention, the side surface portion 11 is made of a highly rigid welded wire net, while the bottom surface portion 12 is made of a parallel structure of the connecting wire rods 12a instead of the welded wire net, thereby integrating the civil engineering structure A described later. It is possible to exhibit a plurality of functions such as a function, a cost reduction function by reducing the number of wires, and a weight saving function.

And at least a plurality of reinforcing members 40.
By connecting the body panels 10 in the length direction, the length of the futon basket 1 can be extended. Note that FIG. 2 shows only one end of the continuous futon basket 1.

<2> Edge panel.
The end panel 20 is a face material that closes both ends of the futon basket 1.
In this example, a rectangular welded wire mesh is adopted as the end panel 20. Note that the present invention is not limited to this, and a welded wire net having an L-shaped cross section, which has a horizontal portion at the lower end of the side surface portion, may be adopted.
It is desirable that the mesh pitch of the end panel 20 corresponds to the pitch of the side surface portion 11 of the main body panel 10.

<3> connecting material.
