The civil engineering structure using a conventional futon basket has a small particle size filling material that flows out of the mesh or moves and meshes with each other after a certain period of time. The entire filling material sinks.
Here, the welded wire mesh futon is excellent in rigidity, but it is not very flexible, and even if the filling material in the lower futon is sinking, the bottom of the upper futon can not be deformed following it. A gap G is formed at the top of the filling material (FIG. 5). In this manner, the upper middle packing material and the lower middle packing material are edge-cut into the bottom surface, so that the civil engineering structure has an unstable structure with weak integration.

  In view of the above problems, an object of the present invention is to provide a main body panel and a futon bag of a futon bag having both rigidity and flexibility, and a civil engineering structure having a strong unity.

The main body panel of the futon basket of the present invention has a side surface portion composed of a plurality of vertical wire rods and a plurality of horizontal wire rods substantially orthogonal thereto, and a bottom surface portion composed of a plurality of connection wire rods extending in the width direction. Both ends of the wire are continuous with the vertical wire.
According to this structure, it is possible to improve the followability to the filling material, reduce the material cost, and reduce the weight by reducing the number of wires on the bottom surface.

The main body panel of the futon basket of the present invention has a plurality of connecting wires extending in the width direction, and a plurality of connecting wires extending in the width direction. It consists of a plurality of reinforcing wires orthogonal to each other, the vertical wire is continuous with both ends of the connecting wire, and the reinforcing wire is located only in the vicinity of both ends in the width direction of the bottom portion.
According to this structure, it is possible to exhibit followability to the filling material at the central portion while reinforcing the side end portion of the bottom surface portion with a lattice structure of reinforcing wires.

The futon bag of the present invention is characterized by comprising a plurality of main body panels arranged in series, a plurality of end panels closing the end, a plurality of connecting members, and a plurality of reinforcing members.
According to this structure, it is possible to provide a futon bag having both rigidity at the side surface and followability at the bottom surface.

The civil engineering structure of the present invention comprises futon baskets and filling materials arranged in a stack.
According to this structure, it is possible to provide a robust civil engineering structure having a desired unit of strength and a strong integrity of the filling material by combining the side surface portion with excellent rigidity and the bottom surface portion with excellent followability. .

Since this invention is provided with the above structure, it has at least one of the following effects.
<1> Since the bottom surface portion is not a lattice structure but a parallel structure of wire rods, it is easy to open and has flexibility to follow the shape of the filling material. For this reason, even if the filling material in the lower futon bowl sinks, the upper connecting wire opens, and the upper filling material and the lower filling material mesh with each other, preventing the generation of voids, A robust civil engineering structure in which the upper and lower filling materials are firmly integrated can be constructed.
<2> The manufacturing cost can be reduced by reducing the number of wires on the bottom surface.
