and the line 13d is positioned both from above to the right elbow above the separation line 2.

All lines shown in FIG. 3 are electrically welded at their respective intersection points. Only the intersecting lines of line 12a of intermediate @9a are welded together, and at the intersection of rectangular line 8a with lines 12b and 12cK or the intersection of rectangular line 8b with lines 12b and 12c, these intersecting lines are welded apart. The wires 1, 2, etc. are also welded together.

FIG. 3 shows a portion of the first embodiment of the invention after completion.

This network structure includes a lower mesh product A1 having a square or rectangular mesh, and an upper mesh product B1 that is identical to this mesh product λ1, and the mesh of the mesh product A1 is connected to all the meshes of the mesh product B1. facing and also facing the separation lines 1.2 and 3. Thus, each straight section of standoff lines 1, 2 and 3 is diagonal to each line of the netting.

In the above example, lines 12a, 12b.

・A force l is formed on the upper net product B2 by 17e, and the net product A2 and the net product B2 have the same shape.

This network structure consists of lines 1, 2 and 3 shown in FIG.
Separation lines 18a, 18b and 18C very similar to
It will be completed soon. Compared to the above-mentioned implementation side numbers, some of the mesh products of the embodiment of FIG. 4 are laterally offset by half a mesh. The separation line 18a passes between the vertical line 15a and the horizontal line 17a at their intersection, between the vertical line 14a and U'ti a 16 a at their intersection, and similarly between the vertical line 15b and the horizontal line Ya, 17b. street,
Then, it passes similarly between the vertical line 14a and the horizontal line 16b. The next separation line 18b is mf: gap 15b and horizontal line 17
a f, vertical line 14b and horizontal @16a, vertical line 15・C
and the horizontal line 17b. At each intersection of these nets, one separation line intersects both the horizontal and vertical lines. At each intersection, the three wires are electrically welded together. In the embodiment of FIG. 3, one spacing line is welded to the vertical and horizontal lines in one half of the intersection, and two of the nettings in the other half of the intersection.
The lines of the book are simply welded together.

In FIG. 5, the mesh structure shown is the same as that of the lower silk product A3 having a square or rectangular mesh.
It consists of a mesh product B3 having a mesh facing the mesh. The separation line is separation line 18a shown in FIG.

Similar in shape to 18b and 18c, but instead of being welded to two adjacent lines as shown in FIG. result in a certain kind of interpenetration. In this embodiment as well, the standoff lines are welded at each intersection.

In the embodiment e shown in FIGS. 1 to 5, the transverse lines are welded on the inside of the spacing line elbow, while the longitudinal lines are also welded on the outside. Since it has proven rather difficult to position all the transverse lines as described above, in the embodiment described below this difficulty has been overcome to produce a network of the type described above. It brings another advantage in doing so.

In the embodiment shown in FIGS. 6 to 9, two identically shaped net products A6 and BaFi having square or rectangular meshes, vertical lines 27a and 27b and horizontal line 28a are used.
and 2Bb.

Compared to the embodiment of FIG. 3, one of the two net products is 89
As shown in the figure, half of one mesh is shifted in the vertical and horizontal directions, and this shift may have a different size from the size shown in the figure, and the reason for providing this shift will be explained later.

The two nettings A6 and B6' are provided with spacings i?331, 32°33 and 34 forming a zigzag (C) as shown in FIG. have

Each L 31a, 32a and 33a below the separation line corresponds to the horizontal line 28. of the net product A6. a, and these elbows are welded vertically in turn at 27a.

By the same method, each elbow 31b above the separation line,
32b and 33b are electrically welded to the horizontal line 28b of the netting B6, and these elbows are in turn connected to the vertical line 27bvc.
be welded.

Accordingly, with this configuration the meshwork is more easily assembled, since the elbow of the separation line will be located completely between the two meshworks A6 and B6.

This assembly proceeds as follows. After approximately locating the separation line, as shown in FIG.
All but a and 32b are firmly embedded in an injectable compound 35, such as polyurethane foam. A plurality of holes 36 are provided in this layer of compound.

Next, a plurality of &[ to form net products A6 and B6 are positioned such that their respective intersections are in contact with L yl 32 a and 32 bK. These three lines are the 10th
They are electrically welded together using electrodes as indicated by the arrows in the figure. Hole 36 is designed to provide a passage for a welding electrode.

The reason why multiple lines can be welded as described above is because portions of the netting are offset in the longitudinal and lateral directions, as shown in FIG. The position of the electrode during the welding operation is also indicated by arrows in FIGS. 7 and 8.

After the wires have been welded together, the holes 36 can be left behind by inserting cylindrical or frustoconical plugs, preferably of the same material as compound 35.

The embodiments shown in FIGS. 11 to 14 are particularly easy to assemble. This example consists of two preformed mesh products A7 and B with square or rectangular mesh.
7 and one preformed separation line C7. The spacing @C7 consists of a plurality of lines in a zigzag shape and a group of parallel straight lines that are welded at the elbow in a direction transverse to the zigzag shape. The separation line C7 shown in FIGS. 13 and 4 is manufactured by the same method as shown in FIGS. 1 and 1a. The relative position l of the zigzag-shaped lines mentioned above is the same as shown in FIG.

Net products A7 and B7 and separation line C7 are connected to separation line C7
are assembled by bringing the Elcera net products A7 and B7 together at the intersection and welding them together.

The embodiment shown in Fig. 17 from Fig. 15 is the first embodiment shown in Fig. 11.
This embodiment is similar to the embodiment shown in FIG. However, the two differ in the following points. 8 and B8 to the net product as shown in Figure 15.
The rhombus mesh is made from biased metal sheets. One of the mesh products is preferably offset longitudinally and laterally by half a mesh as shown in FIG. 16, so that it is more difficult to weld the mesh products A8 and B8 apart line C3VC as shown in FIG. It becomes easier. The separation line C8 may have any of the shapes described above. The welding electrode is represented by the seventeenth arrow. In Figure 17, separation @c8 is net product A.
8 and B8VC welded modes are described.

The single-dot chain @ in FIG. 16 indicates the longitudinal direction of the net product, and the net product is manufactured in this direction.

Due to the ease of correctly positioning the three components, the network can be manufactured in a continuous process, so that the embodiments shown in FIGS. 11 to 14 and the embodiments shown in FIGS. 15 to 17 has many particular advantages. This is important when considering all aspects of automatic manufacturing.

The embodiments shown in FIGS. 15 to 17 also have other advantages as follows. When assembling the netting A8 and B8 and the separation line C8, only two lines need to be welded together instead of welding three lines together as shown in all the other embodiments. There is an advantage.

In the description of the embodiments above, the term line is used to characterize the 414 product and spacing@all constituent components. This use of the term full does not imply that the diameter of the wire is particularly small.

In the description of the embodiments above, the separation line 1l-1' is generally oriented in the vertical direction, but it goes without saying that it may also be oriented in the horizontal direction. The ease of positioning on the separation line having the same length as the width of the netting makes the entire three-dimensional mesh structure virtually simple to manufacture.
