2. Description of the Related Art As a civil engineering work on a slope, there is known a Futon car construction method in which broken stones are packed and laid inside a Futon car.

[0003] Futon baskets are usually composed of a bottom net, a front net, a rear net, a left and right width net made of a rhombic wire mesh (also called a woven wire mesh).
It has a lid net, and the bottom net, front net, and rear net are formed from a continuous single net material, and the width net and the lid net are made of the same net material as the bottom net, front net, and rear net. Formed individually. Therefore, in this product, the front net and the rear net are bent upward with respect to the bottom net, each width net is connected to the bottom net via a coil wire, the whole is formed into a box shape with an open top, and the inside is split Can be packed. Note that the lid net is fixed to the upper end of each of the front net, the rear net, and the width net via a coil wire after the stone filling operation is completed.

On the other hand, in recent years, it is often difficult to obtain a large quantity of high-quality large-diameter crushed stones. In such a case, small-diameter crushed stones must be mixed and used. Therefore, in such a case, the futon cage is a front net, rear net, width net,
It is necessary to make the pitch of the mesh of the lid net smaller than that of the bottom net, and to prevent the small-diameter broken stones from being discharged to the outside through the net, so that the futon cage in this case should , Rear net, width net, lid net are all formed individually,
It is necessary to connect via a coil wire.

[0005]

According to the prior art, the mesh materials constituting the front net, the rear net and the width net have different mesh pitches with respect to the bottom net. There has been a problem that the connection has to be individually connected to the bottom net and the connection operation is extremely complicated.

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, it is an object of the present invention to use a connecting line to greatly simplify the connecting operation and improve the work efficiency even if the mesh members have different mesh pitches. It is an object of the present invention to provide a connection structure of a net material in a futon car capable of achieving the above-mentioned, and a futon car using the same.

[0007]

According to a first aspect of the present invention, there is provided a mesh material comprising a pair of diamond wire meshes having different mesh pitches, and an adjacent edge of each mesh material. It consists of a connecting line that is commonly inserted into the bent portion of the upper row line, and each mesh material sets a combination of mesh pitches so that the bent portions do not interfere with each other on the connecting line, and through the connecting line The gist is to connect.

[0008] The connecting wire can be formed with retaining members at both ends.

The second invention comprises a bottom net, a front net provided along one long side of the bottom net, a rear net provided along the other long side of the bottom net, and a short net of the bottom net. It is provided with a pair of width nets attached along the side, and a lid net arranged above the bottom net, and at least one of the front net, the rear net, and the net is a connection structure according to the first invention. The gist of the present invention is that the bottom net is connected to a net material having a small mesh pitch, and the bottom net is made to correspond to a net material having a large mesh pitch.

[0010] The pitch of the lid net can be the same as any of the front net, the rear net, and the wide net connected to the bottom net via the connecting structure according to the first invention.

[0011]

According to the structure of the first aspect of the invention, the respective net members can be connected by inserting a connecting line in common into the bent portions of the column lines on the adjacent end sides. Forms a frame at adjacent edges of both nets and also forms a connecting member connecting the nets. In addition, the pitch of the mesh of each mesh material, in the total length of the connecting line,
Any combination can be set as long as the bent portions of the respective column lines do not interfere with each other.

When forming stoppers at both ends of the connecting wire,
The retaining prevents the connecting wire from accidentally falling out of the net material.

According to the structure of the second invention, at least one of the front net, the rear net, and the pair of wide nets is connected via the connecting line even if the mesh pitch is different from the bottom net. Since it can be connected to the bottom net, it can be connected to the bottom net very easily without using a coil wire, and the connection structure can be simplified to save material. The net material connected to the bottom net via a connecting line may be any one or both of the front net and the rear net, or one or both of the pair of wide nets.

If the pitch of the mesh of the lid net is equal to that of the front net, the rear net or the width net connected to the bottom net via the connection structure according to the first invention, the pitch of the net of the lid net becomes small. This makes it possible to form a futon cage having a fine mesh on the top surface with respect to the bottom surface.

[0015]

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

The connection structure of the net members in the Futon basket is such that the net members N1, N2, which are a pair of diamond-shaped wire nets, and the net members N1, N2,
And a connecting line H1 connecting N2 (FIG. 1).

The net material N1 is bent at a predetermined mesh pitch d1 into a mountain shape to form bent portions Na1, Na1,..., And a plurality of column lines Na, Na1,. Are continuously entangled with each other. Further, the net material N1 is held in a planar shape through the frame lines H2, H2 by forming the fixed portions Na2, Na2 by winding both ends of each column line Na around the corresponding frame line H2. The net material N2 has the same structure as the net material N1. That is, the mesh material N2 has a constant mesh pitch d2.
(D2 <d1), bent into a chevron and bent parts Nb1, Nb
are formed from a plurality of column lines Nb, Nb,. Further, the net material N2 is held flat by the frame lines H2, H2 by winding both ends of each column line Nb around another corresponding frame line H2 to form fixed portions Nb2, Nb2. I have.

The connecting lines H1 are formed by bending the column lines Na, Nb on the adjacent edges of the net members N1, N2.
By commonly passing through Nb1,..., The net members N1, N2 can be connected in a freely foldable manner. The pitches d1, d2 of the mesh of the net materials N1, N2 are the bent portions Na1, Na1,.
Any combination can be set as long as 1, Nb1... Do not interfere with each other on the connection line H1. For example,
What is necessary is to set d2 = 50, 65, 75 mm, etc. for d1 = 100 mm. The connecting wires H1 are formed by forming coil-shaped retaining stoppers H1a, H1a at both ends to thereby form the net materials N1, N2.
Has been stopped against. The connecting line H1 is inserted through the coil-shaped fixing portions H2a, H2a,... Formed at each end of the frame lines H2, H2. They are rotatably combined. However, the retaining stopper H1a and the fixing portion H2a may be formed in a single-turn loop shape so as not to excessively project in the direction perpendicular to the connecting line H1 and the frame line H2, respectively (FIG. 2A). ), And may be formed in a hook shape ((B) in the same figure).

The connection structure of the net material in the Futon car can be used in the Futon car 10 (FIG. 3).

The futon cage 10 includes a vertically long bottom net 11, a front net 12a provided along one long side of the bottom net 11, and a rear net 12b provided along the other long side of the bottom net 11. , A pair of width nets 13, 13 attached along the short side of the bottom net 11.
And a lid net 14 as main members. In addition, these net materials are formed in a rectangular shape, and corresponding sides are unified to have substantially the same dimensions. Further, the bottom net 11 and the rear net 12b are made of a continuous single net material, and correspond to the net material N1 having a large mesh pitch shown in FIG. Further, the bottom net 11 has a bent portion Na shown in FIG.
1, Na1... Are formed. Frame lines H2, H2 are attached to both short sides of the bottom net 11, and a common frame line H2 is attached to one long side and both short sides of the rear net 12b. The bottom net 11 and the rear net 12b are separated through the bone line H3 by inserting the bone line H3 in the middle. Therefore, the rear net 12b can be freely bent at the position of the bone line H3, and is freely foldable with respect to the bottom net 11.

The front net 12a corresponds to the net material N2 in FIG. 1 in which the mesh pitch is smaller than that of the bottom net 11, and one long side and both short sides have a common frame line H2. It is installed. Further, the front net 12a is formed with bent portions Nb1, Nb1,... Shown in FIG. 1 along the other long side connected to the bottom net 11. Therefore, the front net 12a can be foldably connected to the bottom net 11 via the connection line H1 by the connection structure shown in FIG.

The width of the width nets 13, 13 is such that the mesh pitch is
1, the same as the rear net 12b, and the mesh of the lid net 14 is the same as the pitch of the front net 12a. A rectangular frame line H2 is attached to the outer periphery of each of the width net 13 and the lid net 14. Width net 1
3 and 13 are foldably connected to each short side of the bottom net 11 via coil wires L1 and L1. That is,
Each width mesh 13 is defined by a frame line H2 on the short side of the bottom mesh 11 and the width mesh 13
And the frame line H2 is connected by tangling the coil line L1 in common. The coil wire L1 is a single wire formed in a coil shape, and can be simultaneously taken in by rotating the frame lines H2 and H2 from one end while rotating and entering the same.

The futon car 10 includes a front net 12a and a rear net 12
b is folded on the bottom net 11, and the width nets 13, 13 are
By folding it up, all members except the lid net 14 can be folded compactly into a flat plate equivalent to the outer dimension of the bottom net 11. Further, the futon car 10 raises the front net 12a, the rear net 12b, and the width nets 13 and 13 and attaches the coil wire L1 to each of the adjacent corners of the front net 12a, the width net 13, the rear net 12b, and the width net 13. By inserting it, it can be assembled in a box shape (FIGS. 3 and 4), and can be packed with stones. After completion of the stone-packing operation, the lid net 14 is moved to another coil wire L.
1, L1..., Front net 12a, rear net 12b, width net 1
What is necessary is just to attach to the upper end of 3,13.

The futon car 10 can be laid in a stepwise manner so that the surfaces of the front net 12a and the lid net 14 having a fine mesh are exposed to the outside on the slope M (FIG. 5). However, the futon cages 10, 10... Are laid in tandem in the longitudinal direction of the bottom net 11, respectively. That is, since the bottom net 11 and the rear net 12b are not exposed to the outside and the possibility that the broken stone is discharged to the outside is small,
Although the mesh may be coarse, the front net 12a and the lid net 14 are provided so that small-diameter split stones are not discharged and the upper futon basket 10 is used.
It is preferable that each mesh is set to a sufficiently fine mesh so that a small-diameter split stone does not fall into the lower Futon basket 10. Further, since the width meshes 13 and 13 are not exposed to the outside in principle, the meshes may be coarse. However, when forming the end faces at both ends of the sloping surface M, or when forming the partition part at the intermediate part, the width nets 13 and 13 prevent the small-diameter crushed stone from being discharged to the outside, or perform stone-packing work. When performing the above, a fine mesh may be set so that the small-diameter split stone does not inadvertently leak into the other adjacent Futon car 10.

In the above description, the futon cage 10
Instead of making the pitch of the lid net 14 smaller than that of the bottom net 11, the pitch of the net of the bottom net 11 may be the same.

Further, similarly to the front net 12a, the rear net 12b may have a mesh pitch smaller than that of the net 11 and may be connected to the bottom net 11 using the connecting line H1.

On the other hand, when the bent portions Na1, Na1... Of the bottom net 11 are positioned on the short side, one or both of the width nets 13, 13 are connected to the bottom net 11 via the connection line H1. Can be. The width net 13 connected by the connecting line H1
Makes the mesh pitch smaller than the bottom mesh 11,
The bent portions Nb1, Nb1,... Are formed on the long sides adjacent to the bottom net 11. Further, the width net 13 on the side not using the connection line H1 may be continuous with the bottom net 11 via the bone line H3, or may be connected to the bottom net 11 via the coil line L1.
However, the front net 12a and the rear net 12b at this time may be connected to the bottom net 11 via the coil wire L1.

That is, the futon car 10 is connected to the connecting line H1.
, At least one of the front net 12a, the rear net 12b, and the width nets 13, 13 can be connected to the bottom net 11.

[0029]

As described above, according to the first aspect of the present invention, a connecting line is commonly inserted into a bent portion of a column line on an adjacent end of a pair of mesh materials having different mesh pitches. By doing so, each mesh material can be connected via a connecting wire without using a complicated coil wire, so that the connecting structure can be simplified and material can be saved.
The coupling work is also simple, and there is an excellent effect that the work efficiency can be greatly improved.

According to the second invention, at least one of the front net, the rear net, and the width net is connected to the bottom net via the connection line even if the mesh pitch is relatively small with respect to the bottom net. Therefore, the same effect as in the first invention can be exerted.
