BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure between a welded wire mesh and a synthetic resin mesh buried underground to prevent collapse of an embankment.

[0002]

2. Description of the Related Art Conventionally, when forming a steep slope, various nets made of synthetic resin are buried in several layers in the horizontal direction, and the ends are constructed so as to cover the slope. Was planted to prevent collapse.

However, if these vegetation grows too much together with the weeds, the vegetation protrudes from the shoulder of the road into the road, narrowing the width of the road and impairing the scenery. ing. At this time, there is a problem that the synthetic resin net exposed on the slope is burned together with the weeds or melted by heat, and thus is not useful for preventing the slope from collapsing.

Therefore, it has been proposed to replace only the portion of the net exposed on the slope with a welding wire mesh. In this case, the connection between the welding wire mesh and the synthetic resin mesh has been devised, and the collapse of the slope has been devised. Occurs, and all of the welding wire mesh on the front collapses,
Even if the rear synthetic resin net remains in the soil, the net is not broken.

For example, the one shown in FIG. 6 winds one end of a synthetic resin net 1 around a rigid band 3 to form a wound body 11 and forms a hook-shaped projection 5 and a vertical projection 6 on a flat plate 10. And a connecting tool 4 in which a plurality of the connecting tools 4 are provided so as to face each other. The connecting tool 4 is arranged below at least the horizontal line 22 of the welded wire mesh 2 in which the vertical lines 21 and the horizontal lines 22 are arranged in a grid and their intersections are integrally welded,
As shown in FIG. 7, the hook-shaped projection 5 and the vertical projection 6 protrude above the mesh. One end in the width direction of the wound body 11 of the synthetic resin net 1 is inserted into the hook shape of the hook-shaped projection 5 of the connecting tool 4, and the mesh of the synthetic resin net 1 is meshed. Through the vertical projections 6 and at the same time
Is pressed into the inside of the vertical projection 6, that is, the hook-shaped projection 5, so that the synthetic resin net 1 and the welding metal net 2 are connected.

[0006]

However, when connecting the synthetic resin net 1 and the welding net 2 to each other, it is necessary to prepare a connecting tool 4 in advance and dispose it below the welding net 2, so that the number of parts is small. There was a problem that increases. Further, while pushing the wound body 11 around which one end of the synthetic resin net 1 is wound toward the hook-shaped projection 5 side of the connecting tool 4 arranged below the welding wire net 2,
The on-site work of passing the mesh of the synthetic resin net 1 through the vertical projections 6 was very troublesome.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a connecting structure of a welding metal net and a synthetic resin net according to the present invention is formed by winding one end of a synthetic resin net around a rigid band. A hook formed by bending one end of each vertical wire of a welded wire mesh in which the body is welded together at the intersections of iron wires arranged in a grid pattern
The wrapping body is fixed by inserting the hooks into the mesh of the synthetic resin net and fitting the hooks inside the portion .

[0008]

According to the present invention, a wound body formed by winding one end of a synthetic resin net around a rigid band is connected to each vertical wire of the welded net.
One end fitted to the inside of the hook part is bent formed, each hook
The from synthetic mesh in is passed through the wound body of the resin network are fixed and welded wire mesh and synthetic resin net has a structure which is connected, a synthetic resin network is embedded in the ground and welded wire mesh When a large tensile force acts on the synthetic resin net, the synthetic resin net does not act partially on the synthetic resin net, but rather acts as a wrapper that distributes the entire force. It is buried in a state where it can exhibit the great strength of the net itself.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing a connection structure between a welding wire net and a synthetic resin net according to one embodiment of the present invention, and FIG. 2 is a schematic perspective view showing an enlarged connection portion. ,
FIG. 3 is an enlarged sectional view of a main part.

The structure of the synthetic resin net 1 is substantially the same as that of the above-mentioned conventional synthetic resin net. For example, polyester, nylon, vinylon or the like is used for plain weaving of various synthetic fiber filaments such as aligned yarns and twisted yarns. The size of the mesh woven by garment and processed with polyvinyl chloride or acrylic resin is 5 to 40
mm, preferably about 8 to 25 mm, and the width of the woven web is about 1.5 to 2.5 m, and a long roll (about 10 to 30 m in length) is suitably used. You.

As the rigid band 3 for winding the synthetic resin net 1, a metal flat plate or a synthetic resin plate is used, and its thickness varies depending on the material.
mm that does not easily bend.
The width should be at least 5 cm or more, preferably about 7 to 15 cm, and the length should be approximately equal to or slightly longer than the horizontal width of the synthetic resin net 1.

One end of the synthetic resin net 1 is tightly wound around this band 3 in a double or triple manner, and is wound firmly so that it cannot be unraveled even if pulled by the frictional resistance between the band 3 and the net 1. Have been forgotten. In this manner, the wound body 11 is formed by winding one end of the synthetic resin net 1 around the band 3.

On the other hand, the welding wire mesh 20 has a plurality of horizontal wires 22 arranged in a grid on a plurality of vertical wires 21 each of which is an iron wire, and the intersections of the vertical wires 21 and the horizontal wires 22 are integrally formed. For example, each of the vertical lines 21 buried in the embankment is provided with a hook 23 bent in a substantially U-shape at one end thereof. In consideration of the thickness and width of the wound body 11 around which the synthetic resin net 1 is wound, the hook 23 has a height H of the rising portion 23a of 10 to 25 mm,
Bending is performed so that the width D of 3b is about 5 to 15 cm. Preferably, each of the vertical and horizontal wires 21 and 22 has a thickness of 5 to 8 mm and a mesh size of about 50 to 100 mm. In addition, since the welding wire net 20 is used by being buried in the soil, it is desirable to use a high-hardness wire that is not easily bent by the earth pressure and to have a sufficient rust prevention treatment on the surface.

A bent portion 24 is formed between the horizontal lines 22 at the other end of the welding wire net 20 on the side of the side of the welding wire mesh 20 so as to protrude in a substantially rectangular shape on the side where the horizontal line 4 is welded. The welding wire mesh 30 having the bent portion 24 is formed so as to rise along the slope of the slope described later.

As shown in FIGS. 2 and 3, the connection between the synthetic resin net 1 and the welding wire net 20 is made by folding each hook 23 bent at the rear end of each vertical line 21 of the welding wire net 20. Part 2
3b is wound around the wound body 11 of the synthetic resin net 1.
, The synthetic resin net 1 is pulled as it is, and the wound body 11 is pulled into each hook 2
By simply fitting the mesh 3 inside, the synthetic resin net 1 and the welding net 20 are easily connected. In this case, the number of parts is reduced as compared with the conventional connection structure because the connection tool 4 is not interposed.

Further, in the connecting structure of the present invention, even when a large tensile force acts on the connecting portion between the synthetic resin net 1 buried in the soil and the welding wire net 20, the synthetic resin net 1 is partially formed. Since a strong tensile force does not act on the wire, the force is dispersed throughout by the wound body 11 around which the synthetic resin net 1 is wound, so that the synthetic resin net 1 may be partially cut off. It can prevent the collapse of the embankment by exhibiting the strength of the net itself.

Such a welded wire net 20 and a synthetic resin net 1
The construction of the embankment becomes very simple when the connection structure with the above is used. That is, as shown in FIG.
4 is placed on the side of the slope to lay the welding wire mesh 20, and as described above, the end of the folded portion 23b of the hook 23 is inserted into the mesh of the synthetic resin net 1 from below, and the synthetic resin Netting 1
To fit the wound body 11 inside each hook 23.
Just by inserting, the synthetic resin net 1 and the welded net 20 are easily and reliably connected.

On the other hand, on the side of the slope, the bent portion 2
4 is placed on the lower side with the bending portion 24 of the welding wire 20 slightly shifted left and right, the welding wire mesh 30 is lifted by inserting the shaft 51 between the bending portions 24, and the shaft 51 is supported by the fulcrum. The welding wire mesh 30 is expanded at a predetermined inclination angle forming a slope with respect to the welding wire mesh 20.

When the welded wire mesh 20 and the synthetic resin mesh 1 are connected via the winding body 11 and the welded wire meshes 20 and 30 are connected by being spread at a predetermined angle, respectively, as shown in FIG. The earth and sand 52 is filled and is torsioned. At this time, the welding wire mesh 30 is a horizontal line 2 at the ends of the welding wire meshes 20, 30.
Due to the abutment of the welding wires 2 and 22, the structure does not spread more than a predetermined inclination angle, and even if the earth pressure is applied to the welding wire mesh 30 to spread it, there is no concern that the earth pressure spreads more than a predetermined desired angle. A slope is formed at the connected angles. Thereafter, the above operation is repeated to form an embankment having a slope of a predetermined height.

Since the inclination angle of the welding wire mesh 30 can be adjusted by the shape of the bending portion 24 formed on the welding wire meshes 20, 30, each bending portion 24 is bent so that the slope has a desired inclination angle. It should be processed.

[0022]

As is clear from the above description, in the connection structure of the welding wire net and the synthetic resin net of the present invention, the number of parts can be reduced, the workability is extremely good, and after the connection, the synthetic resin There is a remarkable effect that a concentrated load is not applied to a part of the net making and the net is not torn.
