Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a net connection structure buried in the ground to prevent the collapse of the embankment.

[0002]

[Prior Art]

 Conventionally, when constructing a steep slope, various synthetic resin nets were buried horizontally in multiple layers, and the edges were constructed so as to cover the slope, and plants were planted on the slope. , It was designed to prevent the collapse.

However, if these plants grow too thick together with the weeds, the plants may protrude from the road shoulders into the road, narrowing the road width and spoiling the landscape. Is being done. At this time, there was a problem that the synthetic resin net exposed on the slope was burnt together with the weeds and melted by heat, so that it was not useful for preventing the slope from collapsing.

Therefore, replacement of only the net exposed on the slope with a net made of metal has begun to be studied, and various metal nets have been proposed to prevent slope collapse.

[0005]

[Problems to be solved by the device]

 However, the metal net is heavy, and when it is desired to cut it to an appropriate length, there is a problem that it cannot be easily cut on site.

To solve this problem, a metal net is used for the net that appears on the slope, and the net that is buried in the ground is a synthetic resin that is lightweight, easy to handle, and easy to cut. Attempts have been made to connect these contact points in the ground by using a net made of metal.However, even though the net made of metal and the net made of synthetic resin have high tensile strengths, respectively, the connecting part There was a problem that the strength of the was extremely small.

That is, when the slope collapses, all of the metal net on the front collapses, the rear part using the synthetic resin net remains in the soil, and the net side made of synthetic resin is connected. It happened that the division was torn apart.

Therefore, earnest research was conducted to investigate the cause and solve the problem.

[0009]

[Means for Solving the Problems]

 The present invention has been made in view of the above circumstances, and has a structure in which a metal net and a synthetic resin net are connected, and one end of the synthetic resin net is wound around a rigid band. Is fixed on a metal net so that the wound body does not rotate, and the two are connected.

[0010]

[Action]

 The present invention has a structure in which one end of a net made of synthetic resin is wound around a rigid band, and the winding body is fixed on a metal net so that the winding body does not rotate. When a large tensile force acts on the synthetic resin net and the metal net that are used, the synthetic resin net does not have a partial strong tensile force, but the force is dispersed by the wound body. Since the net made of synthetic resin can exert the great strength of the net itself, it does not tear as in the past.

[0011] Furthermore, the winding body is placed on the metal net and is fixed so as not to rotate, and the connecting portion is not separated. Moreover, since the workability is very good, the construction time can be shortened.

【Example】

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

FIG. 1 is a front view showing an embodiment of the connecting structure of the present invention, and FIG. 2 is a plan view of the same embodiment.

In FIG. 1, reference numeral 1 designates a synthetic resin net, which is a plain weave fabric of polyester, nylon, vinylon, etc. of various synthetic fiber filaments such as aligned yarns and twisted yarns, and is made of polyvinyl chloride or acrylic resin. The size of the mesh processed by 5 to 40 mm, preferably about 8 to 25 mm, and the width of the woven net is about 1.5 to 2.5 m. -30 m) are preferably used.

Further, in FIG. 1, reference numeral 2 denotes a metal net, which is obtained by integrally welding iron wires arranged in a grid pattern at their intersections. The wire rod has a thickness of 5 to 8 mm and a mesh of mesh. A size of about 50 to 100 mm is preferably used. Considering the strength of the welded part in particular, it is desirable that the size of the mesh is a rectangle long in the width direction. Further, since the net is used in soil, it is desirable to use a high-hardness wire that is hard to bend due to earth pressure and to sufficiently rust prevent the surface of the wire.

In FIG. 1, the vertical line 22 and the horizontal line 12 of the metal net 2 are welded at their intersections as described above, but the end portions of the vertical line 22 and the horizontal line 12 are joined by two horizontal lines so as to withstand a tensile force. It is desirable to carry out reinforcement such as heavy welding or welding of a long thin plate.

In the figure, 3 is a rigid strip for winding a synthetic resin net, and a metal flat plate or a synthetic resin plate is used. Although the thickness varies depending on the material, it should be 3 to 10 mm and not easily bent. The width is at least 10 cm or more, preferably 20 to 30 cm, and the length may be approximately the same as or slightly longer than the width of the net made of synthetic resin.

One end of the net 1 made of synthetic resin is firmly wound around the band 3 in a double or triple manner, and is firmly fixed so that it cannot be unraveled even if it is pulled by the frictional resistance between the band 3 and the net 1. Wind around. The one obtained by winding one end of the synthetic resin net around the strip 3 in this manner is called a winding body 11. The wound body 11 is placed on the metal net 2, and the two are connected by a connecting tool.

In the figure, 4 is an example of a concrete connecting tool for connecting a synthetic resin net and a metal net, and the connecting tool 4 is shown in a perspective view in FIG. The flat plate 10 is provided with a plurality of hook-shaped protrusions 5 and vertical protrusions 6 facing each other.

As shown in FIGS. 1 and 2, the connector 4 is located under the metal net 2, and the hook-shaped projections 5 and the vertical projections 6 are projected from the mesh of the net 2. Then, one end in the width direction of the wound body 11 around which the synthetic resin net 1 is wound is inserted into the hook shape of the hook-shaped projection 5, and the vertical projection 6 is passed through the mesh of the net 1. At the same time, the other end of the winding body 11 is pushed into the inside of the vertical projection 6, that is, the hook-shaped projection 5 side. At this time, the position 21 of the end of the net 1 wound around the winding body 11 may be on the lower side of the winding body 11 as shown in FIG. Since the winding body 11 is pressed downward by the hook portion of the hook-shaped projection, the winding body 11 does not come off from the connector 4. In reality, the two nets 1 and 2 are pulled in opposite directions in the soil, and at that time, the connector 4 is pulled in the direction of the arrow P, but the hook-shaped projection 5 stops at the horizontal line 12 of the net 2, The vertical projection 6 also stops at another horizontal line 12. In the tensioned state of both nets 1 and 2, the synthetic resin net 1 pulls on the metal net 2 via the wrapping body 11, so that a specific thread forming the net 1 may be intensively loaded. Since it does not exist, disconnection from the connecting portion does not occur easily.

FIG. 4 is a front view of a connecting structure showing another embodiment of the present invention, in which the synthetic resin net 1 is wound around the strip 3 and the wound body 11 is placed on the metal net 2. It is placed and bound together with the net 2 through the mesh of the net 2 so that the wound body 11 does not rotate with a rope or wire having sufficient strength (hereinafter referred to as wire 30). At this time, it is important to tie at least a plurality of horizontal wires 12 of the metal net 2 so as to enter the bundle.

As described above, in the present invention, the synthetic resin net 1 and the metal net 2 may be connected by using a special connecting tool as shown in FIG. 3, or by a wire or the like as shown in FIG. May be united. In short, it does not deviate from the technical idea of the present invention as long as the end of the synthetic resin net 1 is wound around the strip and the wound one is overlapped and connected on the metal net.

[0023]

[Effect of the device]

 As is apparent from the above description, the connection structure of the present invention has extremely good workability, and since a concentrated load is not applied to a part of the synthetic resin net after the connection, the net is torn. There is a remarkable effect that there is no.
