Abstract
Description
Technical Field
[0001] The present invention relates to a panel unit and a futon cage, and particularly to a panel unit having a folding structure that is easy to transport and a bottomless futon cage that is easy to assemble.
Background Art
[0002] A futon cage is a cage used for civil engineering applications such as retaining slopes, coastal protection, and riverbank protection. A futon cage is formed by assembling a wire mesh into a box shape and filling it with a filling material inside. As a conventional technology related to a futon cage, Patent Document 1 discloses a futon cage including a panel unit having a reverse U-shaped cross section in which two opposing side meshes and a bottom mesh are integrated, and an end face mesh that closes the ends of the panel unit (FIGS. 6A to 6H). Further, Patent Document 2 discloses a bottomless futon cage formed by combining main body panels having a substantially L-shaped cross section. When constructing civil engineering structures such as retaining walls and riverbank protection using a bottomless futon cage, the main body panels are arranged in parallel facing each other along the continuous direction of the retaining wall or the like, the space between the main body panels is connected with a reinforcing material, and the outermost ends are closed with an end face mesh and crushed stones or the like are put into the inside.

Summary of the Invention
Problems to be Solved by the Invention
[0004] The futon cage composed of the panel unit having a reverse U-shaped cross section in Patent Document 1 has a problem that the amount of wire mesh used is large and the material cost is high because the side mesh and the bottom mesh are of an integral structure. In particular, the material cost increases as the design has a larger cross section. In addition, since it is necessary to manufacture futon cages in a plurality of sizes according to the cross-sectional width required in the design, product management is complicated. On the other hand, the bottomless futon cage of Patent Document 2 does not have a bottom net, so the amount of material used is significantly less and the material cost is low. In addition, since the amount of the main body net used is constant with respect to the cross-sectional width of the futon cage, the unit price of the material becomes lower as the cross-section becomes larger for the futon cage with a bottom. On the other hand, at the time of assembly, since the two main body panels have to be transported separately, it takes time for installation, and it takes labor to connect the two main body panels to the reinforcing material.
[0005] An object of the present invention is to provide a panel unit and a futon cage for solving the problems of the prior art as described above.
Means for Solving the Problems
[0006] The panel unit of the present invention is a main body panel in which a side net and a bottom net are connected in a substantially L-shaped cross section, and two main body panels in which each bottom net is arranged in an opposing direction, and a middle frame spanned between the two main body panels, and a plurality of connecting members connecting the main body panel and the middle frame, and the connecting member rotatably holds the vertical wire of the side net and the vertical frame of the middle frame, so that the two main body panels are configured to be foldable so that the two side nets are close to each other.
[0007] The panel unit of the present invention may be configured such that the bottom net is foldable with respect to the side net.
[0008] The panel unit of the present invention may have a width such that the width of the bottom net does not interfere with the opposing main body panels in the folded state of the panel unit.
[0009] In the panel unit of the present invention, the middle frame may be composed of two divided frames arranged in parallel in the width direction, and the two divided frames may be connected to be foldable with each other.
[0010] The connecting member of the panel unit of the present invention may be a metal coil.
[0011] The futon cage of the present invention includes a panel unit and an end face net that connects between two side nets at the end of the panel unit, and is characterized in that an opening surrounded by the bottom face net and the end face net of the panel unit is formed at the bottom.
Effects of the Invention
[0012] The panel unit and the futon cage of the present invention have at least one of the following effects due to the above-described structure. <1> Since it has a bottomless structure with an opening at the bottom, the material cost is low. <2> By combining an end face net corresponding to the cross-sectional width with a main body panel of a single standard, it can correspond to various cross-sectional widths. Therefore, the number of member standards can be reduced, and product management is easy. <3> Since it is an integrated structure in which two main body panels are foldably connected, it can be transported in a folded state and assembled simply by unfolding it at the installation location. Therefore, transportation is easy and the work efficiency of assembly is high.

Best Mode for Carrying Out the Invention
[0014] Hereinafter, the panel unit and the futon cage of the present invention will be described in detail with reference to the drawings. In the present invention, the "length" of the futon cage, panel unit, and each member means the dimension in the longitudinal direction of the futon cage in FIG. 1, and the "width" means the dimension in the width direction of the futon cage in FIG. 1, respectively.
Embodiment
[0015] [Futon cage] <1>Overall configuration (FIG. 1) The futon cage A of the present invention is a bottomless futon cage that can be easily assembled. The futon cage A includes at least a panel unit 1 and an end face net A1 connected to the end of the panel unit 1, and forms an opening H surrounded by the panel unit 1 and the end face net A1 on the bottom surface. In FIG. 1, the smallest unit of the futon cage A consisting of one panel unit 1 and two end face nets A1 is shown, but the number of panel units 1 is not limited to this, and the length of the futon cage A can be extended by connecting a plurality of panel units 1 in the length direction. Since the futon cage A has a substantially bottomless structure with an opening H on the bottom surface, the material cost is low, it is lightweight, and easy to transport.
[0016] <2>Panel unit (FIG. 2) The panel unit 1 of the present invention is a unit for the futon cage A. The panel unit 1 includes at least two main body panels 10 with the bottom net 12 arranged inwardly, a plurality of middle frames 20 spanned between the two main body panels 10, and a plurality of connecting members 30 connecting the main body panels 10 and the middle frames 20. In this example, a combination of two main body panels 10, three middle frames 20, and six connecting members 30 will be described. The number of members of the middle frames 20 and the connecting members 30 in one panel unit 1 is not limited to this. For example, there may be one middle frame 20. The panel unit 1 is characterized by a structure in which the two main body panels 10 can be folded so as to be close to each other.
[0017] <2.1> Main body panel The main body panel 10 is a wire mesh panel that constitutes the side surface of the panel unit 1. The main body panel 10 is made of a wire mesh that is substantially L-shaped in side view and includes a side net 11 and a bottom net 12. In this example, a welded wire mesh with a height of 500 mm × a length of 2,000 mm × a bottom width of 100 mm is adopted as the main body panel 10. By setting the width of the bottom net 12 (100 mm) to be smaller than the thickness of the folded panel unit 1 (about 110 mm), the bottom net 12 does not interfere with the side net 11 when folding, so the minimum thickness can be achieved. In this example, zinc-10% aluminum alloy plated iron wire is adopted as the material of the main body panel 10. However, it is not limited to this, and zinc-plated iron wire or the like may also be used.
[0018] <2.2> Middle frame The middle frame 20 is a member that has both the reinforcement function of the futon cage A and the folding function of the panel unit 1. The middle frame 20 is formed by assembling wire rods into a frame shape corresponding to the cross-sectional shape of the futon cage A. In this example, as the middle frame 20, a metal frame formed by assembling a plurality of vertical frame members 20a having a length corresponding to the height (500 mm) of the futon cage A and a plurality of horizontal frame members 20b having a length corresponding to the width (1,000 mm) of the futon cage A is adopted. The middle frame 20 is arranged between the side nets 11 of the two opposing main body panels 10, and both sides of the middle frame 20 are connected to the side nets 11 of the main body panels 10 by the connecting members 30. By connecting the opposing main body panels 10 with the middle frame 20, it is possible to prevent the side nets 11 from bulging out or deforming due to the lateral pressure of the filling material.
[0019] <2.3> Connecting Member The connecting member 30 is a means for connecting the main body panel 10 and the middle frame 20. In this example, as the connecting member 30, a metal coil wound around the wire of the wire mesh is adopted. The metal coil is wound around the vertical wire 11a of the main body panel 10 and the vertical frame member 20a of the middle frame 20, and the upper and lower ends of the coil are crushed to connect the main body panel 10 and the middle frame 20 rotatably. However, the connecting member 30 is not limited to the connecting coil, and it may be a metal ring, a binding band, or the like. The key is that it should have a structure that can connect the main body panel 10 and the middle frame 20 rotatably.
[0020] <3> End Face Net The end face net A1 is a wire mesh panel that constitutes the end face of the futon cage A. The end face net A1 has the same height as the main body panel 10. In this example, as the end face net A1, a welded wire mesh with a height of 500 mm × a width of 1,000 mm is adopted. In this example, as the material of the end face net A1, a zinc - 10% aluminum alloy plated iron wire is adopted. However, it is not limited to this, and a zinc - plated iron wire or the like may also be used. The end face net A1 is connected to the end of the main body panel 10 by a connecting member such as a connecting coil.
[0021] <4> Folding Method From the state where the panel unit 1 is deployed on the ground, grasp one of the main body panels 10 with both hands and fold it obliquely from the diagonal direction so as to approach the main body panel 10 on the opposite side (Figs. 3A and 3B). By folding, the panel unit 1 becomes a bundle of flat plate - like bodies, and by the operator putting fingers on both sides of the main body panel 10, it can be easily carried by one person (Fig. 3C).
Example
[0022] [Example of the structure where the bottom net is foldable] In this example, the bottom net 12 of the main body panel 10 has a foldable structure. Specifically, the side net 11 and the bottom net 12 are separate members, and the side edges of the bottom net 12 are rotatably connected to the lower edges of the side net 11 via metal coils (Figure 4). In the case of this example, by folding the bottom net 12 to the outside of the side net 11, when the entire panel unit 1 is folded, the bottom nets 12 do not interfere with each other. Therefore, while ensuring the width of the bottom net 12, the panel unit 1 can be folded flat.
Example
[0023] [Example of the structure where the middle frame is foldable] In this example, the middle frame 20 has a foldable structure. Specifically, the middle frame 20 is composed of a combination of two split frames 21, and the two split frames 21 are arranged in parallel in the width direction (Figure 5). The two split frames 21 are rotatably connected to each other by metal coils at the adjacent vertical frame members 20a. As a result, the panel unit 1 can be folded into a substantially M - shaped in plan view. In the case of Example 1, when the panel unit 1 is folded, while the overall width becomes smaller, the length in the folded state is longer than that in the unfolded state. On the contrary, in this example, since the middle frame 20 can be folded into a substantially M - shape, the panel unit 1 can be folded with the same length as in the unfolded state. This makes transportation easier and reduces the storage space required.
