DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a square basket used in revetment work, residential land development work and the like.

[0002]

2. Description of the Related Art Conventionally, as this kind of square basket, there has been known one as shown in FIGS. In general, a trunk net 1 is formed by a rhombic wire net into a rectangular cylindrical shape whose both ends in the axial direction are open, a lid net 2 which closes both open ends of the trunk net 1, and these trunk nets 1 and lid nets 2 And a connection frame line 3 for connecting each of the column lines 1a in the trunk network 1.
A ring 4 for inserting a connection frame line is formed at an end of the body frame 1, and a bone line 5 is inserted into each corner of the trunk network 1. When connecting the trunk net 1 and the lid net 2, the frame line 2 a of the lid net 2 is sandwiched between the ends of the two column lines 1 a, 1 a crossing each other at the open end of the trunk net 1. In this state, the connecting frame line 3 is inserted into the ring 4 at the end of the row line, and the adjacent connecting frame lines 3 and 3 are entangled with each other and joined together.
The end of the bone line 5 inserted into the corner of the
a or the connection frame line 3 so as to be joined.

However, as described above, the bone line 5 inserted into each corner of the trunk net 1 is connected to the frame line 2a or the connection frame line 3 of the lid net 2 by bending it at the site when the lid net 2 is attached. The method of making is that the diameter of the bone line 5 is 4 to 5 mm.
Due to the extremely high rigidity, the bending work is not only troublesome and troublesome, but also it is difficult to accurately fold it to the designed length of the basket, There has been a problem that the dimensions of the basket change and errors easily occur.

That is, this kind of square basket is generally
Because it is formed by a rhombus wire mesh that sequentially connects column lines bent in a flat spiral shape, it is extremely unstable in dimensions,
It relatively easily expands and contracts in the length direction (axial direction) or width direction, and the expansion and contraction ratio may reach 3 to 4%. Therefore, even if the trunk net is formed to the designed dimensions, the dimensions after the installation change due to the acting force of the padding or the like often cause errors. For example, if 10 square baskets with a length of 2 m are arranged side by side and if there is a total expansion and contraction of 3%,
The dimensional error is as large as 60 cm.

In assembling the basket, if the above-mentioned bone line 5 can be bent accurately and locked to the two lid nets 2 in accordance with the design length of the basket, the bone line 5 itself does not expand and contract. Although the distance between the two lid nets 2 and 2 can be prevented from being widened, the length of the basket can be maintained as designed, but it is difficult to bend the bone line 5 to the correct length as described above. For this reason, it is impossible to prevent the dimensions of the basket from being changed from the design values by the bone line.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to simplify the assembling operation by eliminating the need for bending the bone line inserted into the corner of the trunk network at the site, and to prevent dimensional changes due to the bone line. It is an object of the present invention to provide a square basket with high dimensional accuracy that has surpassed the standard.

[0007]

In order to solve the above-mentioned problems, in the present invention, a rhombic wire mesh consisting of flat spiral row lines is formed into a rectangular cylindrical shape whose both ends in the axial direction are open. And a design length of a basket, which is provided with a ring for inserting a connection frame line for connecting the lid net at an end of the trunk net, and which is inserted in each corner of the trunk net in the axial direction. A bone line having substantially the same length as above and having a ring for inserting a connection frame line at both ends, a lid net for closing an open end of the trunk net, and a ring of the trunk net and a bone line. The above-mentioned connection frame which connects the trunk net and the lid net by being inserted is provided, and a square basket which is characterized by the above-mentioned. In the present invention, it is possible to provide a shape retaining middle frame that supports the trunk net from the inside, and it is desirable that this middle frame be connected to the side surface of the trunk net.

[0008]

[Function] Since the connecting frame line insertion ring is formed in advance at both ends of the bone line to be inserted into each corner of the trunk network, the connecting frame line is simply inserted through the ring of the bone line and the column line. The torso net and the lid net and the bone line and the lid net can be connected at the site without bending the bone line, so that the basket basket assembling operation can be performed easily and quickly. In addition, the bone line functions to support the lid nets at both ends of the trunk net and prevent the gap between the two nets from expanding, but the bone line is substantially equal to the designed length of the basket. Because they are formed to the same length,
By keeping the distance between the two lid nets constant by the bone line, the length of the basket in the axial direction can be kept constant, whereby a square basket with excellent dimensional accuracy can be obtained.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a rectangular basket according to an embodiment of the present invention; FIG. It is provided with a square tubular trunk network 10 whose part is open. The trunk network 10 is formed by a rhombus wire mesh formed by sequentially connecting a plurality of column lines 11 bent in a flat spiral shape at a bent portion 11a, and ends of each of the column lines 11 extending in the axial direction of the trunk network 10. A ring 1 for inserting a connection frame line 13 for connecting the lid net
2 are formed.

At each corner of the trunk network 10, the trunk network 1
The bone lines 15 are respectively inserted in the 0 axis direction. These bone lines 15 have substantially the same length as the designed length of the trunk network 10, and are provided with rings 16 for inserting the connection frame lines 13 at both ends thereof. Trunk network 1
In the corner of 0, there are two interconnected column lines 11, 1
One of the bent portions 11a, 11a is inserted so as to engage with both of the bent portions 11a.

A lid net 20 is attached to both ends of the trunk net 10 in the axial direction. The lid net 20 is formed by attaching a frame 21 around a diamond-shaped wire net. As shown in FIG. 4, the frame 21 is formed by two column lines 11, 11 crossing each other at the end of the trunk net 10. In this state, independent connecting frame lines 13 for each side of the trunk net 10 are inserted into the ring 12 of the row line 11 and the ring 16 of the bone line 15 in this state, and the connecting frame line is inserted. 13 is attached to the torso net 10 by wrapping it around the bone line 15 or wrapping it around the adjacent connection frame line 13 and fixing it. In this case, any two adjacent connection frame lines 13 may be inserted into the ring 16 of the bone line 15, but only one of the connection frame lines 13, for example, only the vertical connection frame line 13 is used as the bone line. 15 ring 16
The end of the horizontal connecting frame 13 may be wound around the vertical connecting frame 13 without passing through the ring 16 of the bone line 15.

The thus-assembled square basket is assembled by simply inserting the connecting frame 13 through the ring 12 of the row line 11 and the ring 16 of the bone line 15 to connect the lid net 20 with the trunk net 10 and the bone line 15.
Since it is not necessary to bend the above-mentioned bone line 15 having a large rigidity, the assembling operation can be performed easily and quickly as compared with a conventional basket in which the bone line 15 is bent. Can be.

As can be seen from FIG. 1, one or a plurality of shape-retaining intermediate frames 23 for supporting the trunk network 10 from the inside are provided at intermediate positions inside the trunk network 10 as required. You.
The square frame 23 is preferably arranged in the trunk network 10 with rings formed at four corners and the bone lines 15 inserted through the rings, but the bone lines 15 have rings at both ends. If it cannot be inserted into the ring of the middle frame 23 because of the provision, it is not always necessary to insert it. The middle frame 23 connects at least the front and rear sides 23c, 23c of the upper side 23a, the bottom side 23b, and the front and rear sides 23c, 23c to the side portions 10c, 10c of the trunk net 10.
Furthermore, it is desirable to connect them by connecting lines 24 having a spiral shape or any other appropriate shape, so that the side portions 10c, 10c of the trunk net 10 can be prevented from spreading due to the pressure of the filling stone.

The square basket having the above-mentioned configuration is installed on the site with the inside stuffed with stones. As a method of stuffing stones, a partial opening is formed in the upper surface portion 10a of the trunk net 10 by disconnecting some of the column lines 11, and a method of performing a manual operation through the opening or a method shown in FIG. As described above, the upper surface portion 10
Although there is a method in which a is fully opened and the method is performed by a machine, any method may be used. In the case where the top surface 10a is completely opened and stone-packing is performed, the top surface 10a is closed after completion of the stone-packing, and the bone line 15 inserted at the tip of the top surface 10a is replaced with the corresponding side surface 10c. It is connected to the bone line 15 inserted at the upper end by an appropriate connecting line having a spiral shape or the like, and both ends of the upper surface portion 10a in the trunk net axial direction (that is, the ends of the column lines 11) and the lid net 20 are formed. Is connected by the connection frame line 13 in the manner described above. Note that one of the bone line 15 at the tip of the upper surface portion 10a and the bone line 15 at the upper end of the side surface portion 10c is omitted, and the bone line 15 and the column line 11 are omitted.
May be connected to each other.

Here, even if the pressure caused by the stuffing stone acts on or after the stuffing of stones in the axial direction of the skewer, the bone line 15 inserted into the corner of the trunk net 10 substantially matches the design length of the skewer. It is formed to the same length, and these bone lines 15 hold the two lid nets 20, 20 at both ends of the trunk net tightly via the connection frame line 13, and prevent the gap therebetween from expanding. The length of the basket in the axial direction is kept constant and as designed, and the occurrence of errors due to dimensional changes is reliably prevented.

The trunk net 10 has an upper surface 10a and a lower surface 1
Ob and the front and rear side portions 10c, 10c may be formed independently and connected to each other in a rectangular tube shape by appropriate means, or may be formed by bending a single diamond-shaped wire net. As shown in FIG. 6, when the trunk net 10 is formed of one diamond-shaped wire netting, as shown in FIG. 6, both ends and three intermediate portions of the developed trunk net 10, that is, positions that become corners when folded into a rectangular tube shape. Respectively, the above-mentioned bone lines 15 are inserted, and the ring 12 at the end of the column line 11 and the ring 1 at the end of
After the wire 26 for preventing entanglement has been inserted into the body net 10, the trunk net 10 is appropriately sized with the bone lines 15, 15 at both ends temporarily fixed to each other with a string or the like, as shown in FIG. It is good to fold, transport to the site and assemble. Thus, the trunk network 10 can be easily expanded into a rectangular tube shape simply by lifting the bone line 15 at the site. In this case, since the bone lines 15 are inserted through both ends of the diamond-shaped wire mesh,
At the corner where both ends are located, there are two bone lines 15.

In the embodiment shown in the drawings, a frame 21 is attached around the lid net 20, and the frame 21 is held between the ends of the two column lines 11 in the trunk net 10. The cover net 20 is connected to the trunk net 10 by inserting the connection frame line 13 into the ring 12 at the end of the row line, but without providing the frame line 21 as described above in the cover net 20, A ring similar to the column line 11 of the trunk net 10 is formed at the end of the column line 11 constituting the lid net 20, and the ring of the lid net 20 and the ring of the trunk net 10 are coaxially positioned. The cover net 20 can also be attached to the trunk net 10 by inserting the connection frame line 13 through the ring and the ring of the bone line 15 in common. In this case, out of the four sides of the lid net 20 other than the side where the end of the column line 11 is located, that is, on the side where the bent portion 11a of the column line 11 is located, the bent portion 11a It goes without saying that the connection frame line 13 is inserted.

[0018]

As described in detail above, according to the present invention,
Rings are formed in advance at both ends of the bone line to be inserted into the corners of the trunk network, and the connecting frame is inserted through the ring between the bone line and the column line without bending the bone line at the site. Nets and lid nets,
In addition, since the bone line and the lid net can be connected, the assembling operation can be performed easily and quickly as compared with a conventional basket which is bent at the site by inserting a straight bone line. In addition, the bone line functions to hold the lid nets at both ends of the trunk net and prevent the gap between the two nets from expanding, but the bone line is substantially equal to the designed length of the basket. Since they are formed to have the same length, by keeping the distance between the two lid nets constant by the bone line, the length of the basket in the axial direction can be kept constant and as designed, thereby achieving dimensional accuracy. You can get a winning square basket.
