Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for a geogrid material made of mesh.

[0002]

2. Description of the Related Art Conventionally, various methods have been used to connect geogrid materials at a construction site. The geogrid material is originally used by making use of the tensile force, but it was extremely difficult to connect the meshes of the mesh so as to have the same strength as the tensile force of the main body. Since it is a case of on-site construction, there are restrictions on tools, time, technology, etc., and construction efficiency and cost are also problems, so there was no accurate method.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a connector which is made of an inexpensive material, has good workability, has sufficient connection strength, and can be connected in various forms.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention has a large number of thin mesh-like substrates which are inserted into each mesh on at least one side edge of a strip-shaped substrate. It is formed by attaching hooks.

[0005]

With this structure, the connecting device itself can be obtained in a large amount at a low cost by processing a steel plate or the like. Moreover, the construction is extremely simple because it is only necessary to insert a large number of hooks into the mesh. Furthermore, since each mesh works, each line of the geogrid material exerts its strength, and the same strength as the main body can be secured.

[0006]

Embodiment 1 An embodiment of the present invention will be described in detail below with reference to the drawings. Although it does not define the manufacturing method, an example of the manufacturing process will be described in the order of the processes in order to facilitate understanding. As shown in FIG. 2, the thickness is 3.2 mm, the width is 15 cm,
Substrate 1 made of a long strip of galvanized steel sheet with a length of 1 m
On one side edge 11 of 0, comb tooth-shaped cuts 12 are formed at intervals of 3 cm that matches the mesh of the geogrid material. The width of the cut is 10 mm, the width at the back is 15 mm, and the depth of the cut is 3 cm. As shown in FIG. 1, a large number of notches 12 form a large number of protrusions 13 on the side edges.
Bend this protrusion 13 to the same side at a substantially right angle to form a hook 14,
A connector 1 of geogrid material is formed.

To connect the geogrid material 2 using the connecting tool 1, as shown in FIG. 3, the end portion of the geogrid material 2 to be connected is put on the connecting tool 1 and pressed.
Each of the hooks 14 is inserted into the mesh 21. Next, the mesh 21 at the end of the geogrid material 2 to be connected is inserted. If two Geogrid materials 1 are pulled in the opposite way, the mesh 21
The weft 22 is hooked to the hook 14 and connected. Board 10
Plays a role of preventing the connector 1 from collapsing, so that the connector will not rotate and the hook will not come off. It goes without saying that the two portions of the geogrid material 2 to be connected may be overlapped with each other and the hook 14 of the connecting tool 1 may be pushed in to connect them. A round hole 15 may be opened in some places of the substrate 10, a hook pin 31 may be hit, and the geogrid material 2 may be fixed to the ground 3 via the connecting tool 1.

[0008]

Second Embodiment As shown in FIG. 4, a large number of hooks 14 are attached to the side edges 11 on both sides of the belt-shaped substrate 10 as in the previous embodiment. The hook 14 is slightly rounded and curved inward.
The hook 14 is similarly provided on the opposite side edge 11 to form the connector 1. When using this connecting tool, the mesh 21 is inserted into the hooks 14 on the respective side edges to make the geogrid material 2
Used to connect fellows.

[0009]

Third Embodiment As shown in FIG. 5, a large number of hooks 14 are attached to one side edge 11 of the belt-shaped substrate 10 as in the previous embodiment. The hook 14 is slightly rounded and curved inward.
The other side edge 11 is bent at a right angle in the same direction as the hook to form an angle portion 16. The circular holes 15 are provided in the angle portion 16 at intervals of 5 cm in the longitudinal direction to complete the connector 1 of the geogrid material. The connector 1 of this Example 3 can be used to connect the geogrid material to various objects. A few methods of use are illustrated. In any case, the mesh 21 of the geogrid material 2 is inserted into the hook 14 of the side edge 11 on one side for use.

As shown in FIG. 6, the angle portion 16 is connected to a vertical pile 33 via a U-shaped bolt 32. Figure 7
As shown in, the embedded bolt 35 protruding on the back surface of the wall body 34 is passed through the round hole 15 of the angle portion and the nut is tightened.
It connects with the wall 34. As shown in FIG. 8, the geogrid members 2 each having the connector 1 of this embodiment attached to the ends thereof are connected by bolts and nuts with the backs of the angle portions 16 aligned.
It is convenient when connecting large geogrid materials in a wide area such as soft ground. As shown in FIG. 9, this is an example in which a gap 36 having a constant width is formed between the angle portions 16 to connect them. When making a hole in a part of the geogrid material 2, it is possible to reinforce the part of the hole by such a method.

[0011]

[Embodiment 4] This is an example of using a connector in which the angle portion 16 is bent to the side opposite to the hook 14. When the geogrid material 2 is used to reinforce the embankment, as shown in FIG.
6 is bent to the side opposite to the hook 14 at an acute angle to form a high angle portion. Insert the hook 14 into the mesh 21. Fill embankment 4 on it and roll it sufficiently. Geogrid material 2
Has the effect of preventing the sliding failure of the embankment due to the pull-out resistance due to the frictional force acting between it and the embankment 4 and the tensile strength of the material. Can withstand pulling out. For this reason, the geogrid material 2 can be shortened, so that the embankment 4
It is very effective when the depth is short and sufficient pulling resistance cannot be obtained. In such a case, it is possible to increase the pull-out resistance by integrating the concrete bag 37 or the sandbag formed by pouring concrete into the flexible cloth formwork at the site with the angle portion 16.

After laying the geogrid material 2 on the ground 3,
When winding up, as shown in FIG. 11, attach the connecting tool 1 from the top to the place where you want to bend the geogrid material 2,
The connecting tool 1 is pressed outward, and the geogrid material 2 is rolled up along the outer corner of the angle portion 16. It is convenient because it allows you to roll up materials that are stiff and difficult to bend, so you can wind them up neatly. When the geogrid material 2 is wound up, as shown in FIG. 12, the connector 1 having the angle portion 16 attached to the same side as the hook 14 is used, and another restraining plate material 38 is applied from above the geogrid material 2 and tightened. The method may be taken.

[0013]

[Embodiment 5] This is an example of using the substrate 10 with the hook 14 provided on one side thereof. As shown in FIG. 13, it is convenient when the hook 14 is inserted into the mesh 21 at the end of the geogrid material 2 and the turnpack 39 is attached to the hole on the opposite side to connect with another object.

Other Cases The material of the connector of the present invention is not limited to the embodiment as long as it has high strength such as stainless steel, fiber reinforced plastic, ceramic material. Further, the shape of the hook and the attaching method may be a method in which a separately formed one is attached to the substrate.

The present invention can obtain the following effects. (1) The connector can be produced at a low cost because it can be produced by forming a notch on the side edge of the strip and bending or bending it. (2) Since a steel plate having high strength can be used and there is no labor-intensive process such as welding, mass production is possible. (3) Long products are easily available. (4) Since it is sufficient to insert the hook into the mesh, the construction is very easy. (5) Since each mesh can contribute to the tensile force, it has high strength and high reliability.
