Abstract

PURPOSE:To improve the workability on lifting a mat cage, by arranging flexible reinforcing ropes between side nets oppositely positioned to cross the bottom net and fitting reinforcing ropes so as to freely slide against respective nets. CONSTITUTION:Reinforcing ropes 14 are fitted to mat cages 10 and coils 30 are wound on the outer peripheral face of nets 11, 12, so as to freely slide against the oppositely positioned side nets 12 and the bottom net 11. Since the ropes 14 are attached on the outer periphery of the cage to freely slide, the load acting on the coils 30 and the ropes 14 decreases on lifting the cage and also the position of lifting rings can be easily corrected. Since the rope is flexible and fitted across the opposite nets 12, 11, the net 12 is prevented from bulging out and the net 11 is prevented from deforming on lifting the cage. Since the limit of load acting on the rope is high, the number of ropes and 14 and lifting rings 15 is reduced. In this way, the deformation can be prevented and it can cope with an uneven ground and the lifting rings can be rapidly detached.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a futon basket which can be suspended for use in 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, in the conventional futon basket, a hanging hook is provided for lifting the net material on the side surface of the futon basket or a partition net installed in the middle thereof.

[0003]

Problems to be Solved by the Present Invention The above-mentioned conventional futon basket has the following problems.

<B> Since the futon basket is made of net, the bottom net is easily deformed when it is lifted.

<B> As a method of preventing the bottom net from deforming, a method of manufacturing the bottom net with high strength is considered. However, there is a limit to increase the strength of the bottom net due to the need to cope with the inferiority of the installed ground.

<C> Further, as a method of preventing the deformation of the futon basket, there is a method of increasing the number of hooks installed to distribute the load load on each net. This method has a drawback that the number of processing steps for attaching the hook to the futon basket and the number of steps for attaching and detaching the hanger to each hook increase. There is also a problem that high mounting accuracy is required in order to equalize the load burden on each hook.

<D> In order to distribute and support the weight of the futon basket during lifting, a large number of reinforcing ropes and hanging hooks are attached to the upper end of the covering, so that the hanging hooks can be attached and removed. It is difficult and time-consuming, and it is especially difficult to remove it underwater.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to effectively prevent deformation and to easily lift a futon basket with a small amount of work. To provide.

[0009]

SUMMARY OF THE INVENTION The present invention is a futon basket constructed by erection of side nets at the peripheral edge of a bottom net, and is flexible between side nets facing each other across the bottom net. It is a futon basket characterized in that a reinforcing rope having a property is arranged, and the reinforcing rope is attached so as to allow sliding with respect to each net. In addition, it is a futon basket characterized in that the reinforcing rope is connected by winding a coil around the overlapping portion of the net.

[0010]

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

<B> Configuration of Futon Basket FIG. 1 shows an example of the futon basket 10. The futon basket 10 is composed of a box body formed by vertically arranging a plurality of side nets 12 on 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 21 having a higher strength than the wire net 20 to the periphery of a known wire net 20. A continuous reinforcing rope 14 is attached to the bottom net 11 and the side nets 12 facing each other.

<Ro> Reinforcing Rope The reinforcing rope 14 is a flexible rope material such as a wire rope, and a suspension ring 15 is formed at both ends thereof. The entire length of the reinforcing rope 14 is set so that the height of the suspension ring 15 attached to the upper end protruding upward from the bedding basket 10 is the same.

<C> Rope mounting means As shown in FIG. 2, the reinforcing rope 14 can be mounted on the futon basket 10 so as to be slidable with respect to the side net 12 and the bottom net 11 facing each other. So that the coil 3 is formed on the outer peripheral surface of each net body 11 and 12.
It is done by wrapping around 0. The reason why the reinforcing rope 14 is attached to the outer peripheral surface of the bedding basket 10 is that the reinforcing efficiency at the time of lifting is better than that to the inner peripheral surface. The reinforcing rope 14 may be attached in parallel with the assembly of the futon basket, or may be additionally attached to the completed futon basket. In the present embodiment, the mounting of the reinforcing rope 14 by winding the coil 30 has been described, but other known means that is slidably mounted on the nets 11 and 12 can also be used.

[0014]

[Action]

<A> Stuffing the bedding basket with stones After the aggregate 50 such as quarry is put into the bedding basket 10 shown in FIG. 1, the lid net 13 is attached. The stone stuffing work is performed on site by assembling the bedding basket 10 or at the quarry where the working environment is good, and the bedding basket 10 is loaded on a transportation means such as a truck and transported to the site.

<B> Lifting the Futon Basket Next, as shown in FIG. 4, the lifting device 4 is placed just above the futon basket 10.
0 is positioned, and each hanging hook 41 is hooked on each hanging ring 15 of the bedding basket 10 by the worker. Alternatively, the suspending device 2 may be horizontally moved in the bending direction of the hanging hooks 41, and all the hanging hooks 41 may be simultaneously inserted into the hanging ring 15. When the setting of each hanging hook 41 of the suspending device 2 is completed, the suspending device 40 is lifted by a crane or the like (not shown) as shown in FIG.

<C> Function of the rope material during lifting

Due to the sliding structure of the rope material Since the reinforcing rope 14 is slidably attached to the outer circumference of the futon basket 10, the rope 1 is lifted when the futon basket 10 is lifted.
Since the suspension load applied to the 4 itself can be dispersed, a mounting tool such as the coil 14 for mounting the rope 14 and a roll.
The load on the loop 14 is reduced. Further, the position of the suspension rings 15 formed at both ends of the rope 14 can be easily corrected.

Due to the continuity of the rope material Since the reinforcing rope 14 is a flexible rope material and is attached across the bottom net 11 from the side nets 12 facing each other, It prevents the side nets 12 from protruding (deformation) at the time of lifting, and also prevents the bottom net 11 from deforming. Further, the load concentrated on the connecting portion between the bottom net 11 and the side net 12 at the time of hoisting can be easily avoided / distributed because the reinforcing rope 14 is formed integrally with the side net 12 part and the bottom net 11 part. .

Due to the synergistic effect of the above and the above, since one reinforcing rope 14 has a high limit for receiving a load, the rope 14 is used to lift the futon basket 10. Since it is not necessary to use a large amount, the total number of suspension rings 15 formed at both ends of the rope 14 can be reduced, and the labor for attaching and detaching the hanging hook 41 can be reduced.

<D> Removal of Hanging Device When the bedding basket 10 is bottomed at a predetermined position, the hanging hooks 41 are simultaneously pulled out from each hanging ring 15. Since the hanging rings 15 and the hanging hooks 41 are aligned in the same direction, it is possible for the worker to save the labor of manually pulling out the hanging hooks 41. In particular, it is advantageous when the water depth at the installation site of the futon basket 10 is deep.

[0022]

Other Modifications In the above-described embodiment, the case where the hanging ring 15 is formed in an annular shape and the lower part of the hanging hook 22 is formed in a hook shape has been described, but the ring body and the hook body may be combined in reverse.

[0023]

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

<A> Since the reinforcing ropes are slidably attached, the weight of the futon basket can be evenly distributed without being concentrated and concentrated on the bottom net and each side net. It is possible to effectively prevent the deformation such as the protrusion that occurs in the.

<B> Even with the same material as the conventional futon basket, it has strength comparable to that of a high-strength material due to the additional attachment of the reinforcing rope, and in the bottom net, the inferiority of the installation ground is supported as before. it can.

<C> Since the reinforcement ropes are easily attached to the futon basket by winding the coils, the reinforcement measures and the bar arrangement work can be efficiently performed in a short time without any trouble.

<D> Since the slidable reinforcing ropes can distribute the dead weight of the futon basket, the number of hanging rings can be reduced. You can easily do it in no time. Further, the slidable reinforcing rope makes it easy to equalize the load on each suspension ring.

<E> Since the total number of suspension rings can be reduced, the attachment / detachment operation can be facilitated and the operation time can be shortened.
