Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a futon car which is used in a stair-like and multi-tiered form in slope protection work and seawall protection work.

[0002]

2. Description of the Related Art In a slope protection work and a seawall protection work, a futon car construction method is known in which futon cars filled with stone materials such as cobblestones and split stones are stacked in multiple stages along a slope.

[0003] Futon baskets are usually a combination of a bottom net, a front net, a rear net, left and right side nets, and a lid net formed by attaching a frame to the outer periphery of a mesh material of a rhombic wire net (also referred to as a twill net). It is configured. Therefore, this net is made by connecting the front net, rear net, and side net to each side of the bottom net, standing up, forming a box shape with an open top, filling the inside with stones, and covering the front net with the front net and the rear net. , Can be mounted on the upper side of the side net to close the upper surface.

[0004]

According to the prior art, when the stone material hits the borders of the front and rear nets at the time of stuffing, the front ends of the front and rear nets face inward and downward. In addition, it becomes difficult to attach the lid net, and the front net and the rear net are deformed outward by stuffing stones, so the maximum height is about 5
It has to be limited to about 0 cm, and there is a problem that the required number of stacking stages tends to be excessive.

Accordingly, an object of the present invention is to make the first frame line on the front end side thicker than the second frame lines on both sides for each of the front net and the rear net in view of the problems of the prior art. It is an object of the present invention to provide a futon car which can reduce the number of stacking steps by minimizing deformation of the front net and the rear net at the time of stuffing by mounting a bone line thicker than the frame line of the above.

[0006]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a rectangular bottom net, a front net attached to the long side of the bottom net, a rear net, and at least one of the short nets. Side nets attached to the sides, the front net and the rear net each have the first frame line on the tip side thicker than the second frame lines on both sides, and the bone line thicker than the second frame line. The gist is to attach it in parallel with the second frame line.

[0007] The front net and the rear net can be connected by a partition net.

[0008] The front net may be formed of a net material having a smaller mesh pitch than the bottom net, or a front flat net may be provided at the end.

Further, the bottom net and the rear net can be integrally formed by a single net material.

[0010]

According to the structure of the present invention, the front net and the rear net each have the first frame line on the tip side wider than the second frame lines on both sides, and the bone lines larger than the second frame line are attached. As a result, the overall strength is sufficiently improved, and when stuffing stones, the central part may be deformed so as to bulge outward, or the stone material may be excessively deformed inward, downward, etc. It can be effectively prevented. It is preferable that a thick wire having a wire diameter of 7 to 10 mm is used for the first frame line and the bone line, and a thin wire having a wire diameter of 4 to 6 mm is used for the second frame line. The side net may be provided on both short sides of the bottom net, or may be provided only on one short side of the bottom net, and may be shared with another adjacent futon car.

[0011] If the front net and the rear net are connected by the partition net, the front net and the rear net are reinforced through the partition net, so that outward deformation can be more effectively prevented. In addition, the partition net connects the middle part of the front net and the rear net in the long side direction of the bottom net, and the front net and the rear net have a bone line thicker than the second frame line corresponding to the partition net. Another connecting bone line shall be fitted. Also,
At this time, it is assumed that a bone line thicker than the second frame line is arranged between the connection bone line corresponding to the partition net and the second frame lines on both sides.

The fore net having a smaller mesh pitch than the bottom net strengthens the front surface exposed to the outside when stacking, and prevents leakage of small-diameter stone. In addition, the fore net is a bottom net, by using a connecting line that is commonly inserted into the end of each net material of the fore net,
It can be easily connected to the bottom net without using a coil wire. However, the connecting line may have the same thickness as the second frame line, or may be thicker than the second frame line.

If the front net is attached to the tip of the front net, the front net can partially close the upper surface of the futon car and omit the lid net. This is because the upper surface of the Futon car can be closed by the front net and the bottom net of the upper Futon car. The front net may be formed separately from the front net and connected to the front net, or may be formed integrally with the front net.

By integrally forming the bottom net and the rear net with a single net material, the connecting step can be omitted and the manufacturing cost can be reduced. In addition, the bottom net and the rear net at this time shall be foldable via a partition line, and the partition line may have the same thickness as the second frame line. It may be thick.
