Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a futon basket and a hanging device used for river construction, road construction or various retaining wall construction.

[0002]

2. Description of the Related Art A futon basket comprises a box body whose bottom and side surfaces are surrounded by a net material, and a net lid which closes the upper opening of the box body. Futon baskets are stuffed with stones on site to give weight that can withstand water flow and earth pressure. By the way, the conventional futon basket does not have a special hanging tool. For this reason, hanging wires laid in a crisscross shape are laid under the bedding basket before stone filling, and the ends of the hanging wires are hooked together at one location on the crane hook and hung.

[0003]

Problems to be Solved by the Present Invention The above-mentioned conventional futon basket has the following problems. <B> Since the hanging wire is arranged under the futon basket, it is very difficult to collect the hanging wire after laying the futon basket. <B> Since the end of the hanging wire is concentrated in one place, it is easy for the mesh surface to stick out to the outside when the futon basket is lifted. <C> It may be possible to hang a futon basket with a hook, but the attachment / detachment mechanism with the hook is complicated, and it is not practical.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and it is an object of the present invention to effectively prevent deformation of a futon basket and to hang the futon basket easily.
To provide a futon basket and a hanging device.

[0005]

That is, according to the present invention, in a box-like futon basket having side nets attached to the periphery of the bottom net, bar-shaped reinforcing members are attached to a plurality of side nets across the net surface. The futon basket is characterized in that hanging hooks are formed on top of each reinforcing member in the same direction as each other. Further, according to the present invention, in a suspending device for lifting a futon basket, a rigid frame formed to have substantially the same shape as the plan view of the futon basket and a plurality of hanging hooks hanging on the rigid frame on the extension line of the reinforcement of the futon basket are provided. The hanging device is characterized in that the hanging hooks are formed in the same direction.

[0006]

The present invention will be described below with reference to the drawings.

<B> Futon Basket FIG. 1 shows an example of the futon basket 1. The futon basket 1 is composed of a box body formed by attaching a plurality of side nets 12 to the periphery of a rectangular bottom net 11 and a rectangular lid net 13 that closes the upper opening of the box body. Each of the nets 11 to 13 is formed by attaching a frame body having a higher strength than the metal net to the periphery of a known metal net. Each side network 12
A reinforcing member 14 having a wire diameter larger than that of a wire mesh is attached to the wire in such a manner as to traverse the mesh surface in the vertical direction. Further, a ring-shaped suspension ring 15 is provided at the upper end of each reinforcing member 14 projecting upward from the bedding basket 1.
Are formed. When forming the hanging hooks 15, it is essential that the directions of the openings of all the hanging hooks 15 are aligned in the same direction. The hanging hook 15 may be formed of an independent member other than the reinforcing material. In addition, a band net may be attached inside the futon basket 1 to divide the inner space of the futon basket 1 into a plurality of spaces.

<B> Suspension Device As shown in FIG. 2, the suspension device 2 is composed of a rigid frame 21 having substantially the same shape as that of the blanket basket 1 and a plurality of hanging hooks 22 suspended below the rigid frame 21. To be done. The rigid frame 21 is formed by joining steel materials such as H steel in a rectangular shape, and a suspension bracket 23 for connecting the sling wire 3 is attached to the upper portion of the frame body. As shown in the enlarged view of FIG. 3, the hanging hook 22 has a J-shape as a whole, and a stopper 25 is formed on the upper end thereof.
A hook-shaped bent portion 26 is formed in the lower portion thereof and is provided at the same interval as the hanging hook 15 of the bedding basket 1. The hanging hooks 22 are positioned on the rigid frame 21 so that the bending portions 26 are bent in the same direction. As the positioning means, a combination of a protrusion 27 continuously provided on the circumferential surface of the straight portion of the hanging hook 22 and a modified opening 28 formed on the rigid frame 21 side in accordance with the protrusion of the protrusion 27 is adopted. can do. Further, the spring 4 is fitted under the neck of the stopper 25. The spring force of the spring 4 is set so that the hanging hook 22 can be lowered by hand.

[0009]

Next, the operation will be described.

<a> Filling the bedding basket with stones After putting the aggregate 5 such as quarry into the bedding basket 1 shown in FIG. 1,
Attach the lid net 13. The stone stuffing work may be performed on site, or the bedding basket 1 filled with stones may be transported to the site at a quarry where the working environment is good.

<B> Lifting the Futon Basket Next, as shown in FIGS. 2 and 3, the hanging device 2 is positioned right above the futon basket 1, and the hanging hooks 22 are inserted into the hanging hooks 15 of the futon basket 1. Insert. For the hanging work of the hanging hooks 22, the worker holds each of the hanging hooks 22 by hand, pulls down the hanging hooks 22 against the spring force of the spring 4, inserts the bent portion 26 into the hanging hooks 15, and then the hanging hooks. Release 22. Then, the restoring force of the spring 4 raises the hanging hook 22 until the bent portion 26 is hooked on the upper portion of the hanging hook 15, and prevents the hanging hook 22 from coming out. Alternatively, the suspending device 2 may be horizontally moved in the bending direction of the hanging hooks 22, and all the hanging hooks 22 may be inserted into the hanging hooks 15 all at once. When the setting of each hanging hook 22 of the hanging device 2 is completed,
Lift the suspending device 2 with a crane or the like. As a result, only the rigid frame 21 rises while contracting the spring 4, and when the stopper 25 comes into contact with the rigid frame 21, the lifting force of the suspending device 2 is transmitted to the hanging hook 15, and the futon basket 1 is lifted.
Move to a predetermined position.

<C> Movement of Futon Basket The futon basket 1 is pulled up in the extension direction of the reinforcing member 14 via the hanging hook 22, and the reinforcing member 14 integral with the hanging hook 15 serves as a reinforcing member for each side net 12. Function. Therefore, it is possible to effectively prevent the side net 12 from sticking out by the aggregate 5 even when the futon basket 1 is lifted.

<D> Removal of Hanging Device When the bedding basket 1 has bottomed in place, the hanging device 2 is lowered until the spring 4 is restored, and then the hanging device 2 is retracted. Hanging hooks 22 all at once from the hanging hook 15
Pull out. Since the hanging hooks 15 and the hanging hooks 22 are aligned in the same direction, it is possible for the worker to save the labor of manually pulling out the hanging hooks 22. This is particularly advantageous when the depth of water at the installation site of the bedding basket 1 is deep.

[0014]

[Other Modifications] In the above embodiment, the hanging hook 15 is formed in an annular shape, and the lower portion of the hanging hook 22 is formed in a hook shape. However, the ring body and the hook body may be combined in reverse.

[0015]

[Other Embodiments] FIG. 4 shows another embodiment of the suspending device 2. In this embodiment, the middle of the hanging hook 22a is pivotally supported on the rigid frame 21 by the support shaft 29, the upper portions of the hanging hooks 22a are connected by the connecting member 6, and the hanging hook 22a is oscillated by sliding the connecting member 6. It can be moved and attached to and removed from the hanging hook 15a extending from the futon basket.

[0016]

Since the present invention is as described above, the following effects can be obtained.

<B> Direction and direction of each hanging hook of the futon basket
