プ）のものが提案されている。Futon baskets, that is, square-shaped nets filled with stones, are widely used for construction of flood control facilities such as revetments, jetties, headraces, and root consolidations. Regarding this futon basket, Japanese Patent Publication No. 56-31405 proposes a type (steel material type) using a plate-shaped reinforcing member such as a strip steel.

う問題があった。This steel type futon basket has an advantage that stones can be filled without forming pits in the ground, as compared with a so-called rope type in which a net-like body formed by braiding iron wires is connected. However, in the prior art, since no reinforcing material is provided on the lid net and the bottom net that form the upper and lower surfaces, the weight of the stone material is supported only by the wire net, and when the hoisting movement is performed, a large shape is formed as shown in FIG. When collapsed and deformed, it is thrown into water and grounded, and it swells in the opposite direction, that is, on the side of the lid net. Due to this improper bending, the yield strength of the wire mesh is impaired, and there is a problem that a good shape-retaining state cannot be obtained when the wire meshes are stacked in multiple stages. Further, in this prior art, since the horizontal reinforcing plate and the vertical plate are connected to each other by bolts at the lower end and the upper end, respectively, many bolts and nuts are required, and the number of tightening is increased, so that quick and efficient assembly work is achieved. There was a problem that it was difficult to plan.

It is an object of the present invention to provide a futon basket of this type of steel material, which can realize well-balanced deformation in a well-balanced manner and can be assembled easily and efficiently.

に自在に対応可能となる。Reference numeral 11 is a plurality of bottom strips, and the corner bending portion 1 has bolt holes 111 at both longitudinal ends as shown in FIG. 6 (f).
10, 110 are formed. The bottom strip 11 is arranged below the bottom surface 1a, and the bent portions 110, 110 at both ends are overlapped with the vertical strip 8 as shown in FIGS. 2 and 3, and the bottom strip 11 is provided as shown in FIG. Both the frame A and the frame A are connected by a bolt nut 13. It is preferable that the bottom strip 11 together with the lower frame A, the upper frame B, and the vertical strip 8 satisfy a predetermined condition in order to obtain a good balance between the shape retaining force and the conformability. According to an experiment by the present inventor, the total area of the bottom strip is 1 to 20% of the bottom surface area, assuming that the above-mentioned corner members have the same plate thickness.
The range is, especially preferably 3 to 10%. If the area ratio exceeds the lower limit, the degree of support is good, but the degree of support of the weight of the stone material by the metal net increases, so the shape retention is poor, and the shape deformation becomes large during storage and movement. When the area ratio exceeds the upper limit, the shape retaining force is good, but the rigidity is too high so that the deformation due to the weight of stone material does not easily occur during the work such as embankment, and the conformability to the unevenness of the ground shape and the conformity between the top and bottom when stacking are hindered. Bottom 1 if within the above range
Since a moderate rigidity is given to a and the stone weight applied to the wire mesh is supported by the lower frame A, the upper frame B and the vertical strip 8, the deformation at the time of movement or insertion as shown in FIG. 7 should be made small. You can On the other hand, at the time of embankment, it can be easily deformed by being bent by the weight of the stone material in the car, so that it is possible to deal with unevenness of the ground freely.

A basket made with the side plate 2 made of wire mesh, arranged so as to penetrate the mesh at the boundary position between all the side surfaces and the bottom surface of this cage,
Long and short 2 which forms the lower frame A by connecting the ends to each other
The lower frame strip plates 6, 6, 7, and 7 are formed one by one, and the insertion holes 82 are formed by bending the plates in the plate thickness direction at the upper end, and the bolt holes 81 are formed at the lower end portion. A plurality of vertical strips 8 arranged in a direction orthogonal to the strips 6, 6, 7 and 7 so as to penetrate the mesh of the four side faces 1b, 1c, 2b and 2c, and the four side faces 1.
The upper frames B, 1c, 2b, 2c are meshed at the upper positions and are inserted through the through holes 82 of the vertical strips 8 to hold the middle, and the ends are joined together to form the upper frame B. The upper frame strips 9, 9, 10, 10 each having two long and short,
Square bent parts 11 with bolt holes 111 at both ends in the longitudinal direction
0, 110 are arranged at a predetermined interval on the bottom surface 1a, and the corner bending portions 110, 110 are overlapped with the lower end portions of the lower frame strip plates 6 and 7 and the vertical strip plate 8 and are provided on them. And a plurality of bottom strips 11 coupled by common bolt nuts 13 penetrating the bolt holes 61, 71, 81 provided, and the total area of the bottom strips 11 is in the range of 1 to 20% of the bottom surface area. Due to the certain structure, in addition to the basic advantages of the steel plate reinforced type that does not require pit digging for stone filling, the following excellent effects are obtained.

ができる。A plurality of bottom strips 11 that fit within the range of 1 to 20% of this area are passed to the bottom face 1a of the car, and the bent portions at both ends of the bottom strip 11 are shared with the lower frame A by a common bolt nut 13 and vertically. Since it is connected to the belt 8 for use, an appropriate rigidity is given to the bottom surface of the car to stably support the weight of the input stone material, and the lower frame A and the upper frame B can be used for storage, suspension movement, and water bottom input. The collapsible deformation can be prevented by the cooperation of the vertical strip 8 and the bottom strip 11, and transient bulging on the bottom surface side can be suppressed to perform water bottom injection. And, even when it is installed on the bottom of the water and constructed, the bottom strip 11 stays within the range of 1 to 20% of the bottom surface area as described above, and therefore is bent and deformed by the weight of the stone material in the basket. Therefore, it is possible to adapt to the unevenness of the ground, and also to improve the familiarity between the upper and lower futon baskets when stacking.

0 and 110 are overlapped with the lower end portions of the lower frame strip plates 6 and 7 and the vertical strip plate 8 and bolt holes 61, 71 and 8 provided therein.
Being connected with a common bolt nut 13 that penetrates 1,
The vertical strip 8 has an insertion hole 82 formed at the upper end by bending the plate in the plate thickness direction, and the upper frame B is formed in the insertion hole 82.
Since the upper frame strips 9, 9, 10, and 10 constituting the upper frame B are held by holding the upper frame B, the number of bolts and nuts can be reduced, and the coupling work can be simplified and speeded up. The cost of the futon basket manufactured and installed on site can be significantly reduced.
