Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a connection tool for net boards that is preferably used for embanking a reclaimed land or constructing a reclaimed land.

[Conventional technology]

When constructing embankments and slopes on reclaimed land, for example, mesh-shaped resin net plates have traditionally been used as civil engineering material nets to disperse stress in the embankments and constructed soil. It is being In the case of this resin net board, a common connecting means is to sew the ends of the net board together with a rope or the like.

[Problem that the invention attempts to solve]

However, with these conventional connection methods, it is extremely troublesome and requires a tremendous amount of work time to connect a large number of net boards to each other, especially in a vast area of embankment construction. There are problems such as being unable to work properly.

The present invention has been devised in view of these conventional problems, and aims to provide a connection tool for internet boards that can quickly and accurately connect internet boards to each other.

[Means for solving problems]

In order to solve these conventional problems, the connecting device for the network board of the present invention is constructed as follows.

That is, it is a connecting tool for connecting a pair of mesh-like net boards 1, and connects a plurality of horizontal hook parts 2a formed in an arch shape with a size to be inserted into the mesh of the net board 1 into a pair of parallel hooks at equal pitches. Vertical hook portion 2b, 2
The present invention includes a ladder-shaped connecting band plate 2 and a connecting member 3 installed between b.

With the connecting ends of the pair of net boards 1 overlapped, each horizontal hook part 2a of the tie strip board 2 is inserted through each mesh of both, and the connecting material 3 is inserted into each horizontal hook part 2a inserted through the mesh. The network boards 1 are connected to each other by being inserted through the cables.

[Function] The net board connected by the connector of the present invention is, for example, called a polymer grid, and is made of a resin such as polyolefin such as polyethylene or polypropylene, or polyester such as polyethylene terephthalate or polybutylene terephthalate. Some are biaxially stretched. As for the characteristics of this net board 1, it is desirable that it has enough rigidity and flexibility to be able to be constructed in accordance with the shape of the embankment or reclaimed land, and to maintain the required three-dimensional shape even when used alone. In addition, the connecting strip board 2 is also connected to the net board 1.
It should be of the same quality. In the case of the connecting rod material 3, any material other than rod-shaped resin, lightweight metal pipe, rope material, etc. can be used as long as it has the strength to maintain the required rigidity of the connecting portion between the net boards 1. It may be hot. When connecting, the connecting ends of the two net boards 1 to be connected are overlapped with each other so that the meshes in the same row on both sides are aligned. From this, each horizontal hook portion 2a of the connecting strip plate 2 is inserted through the mesh on one side of the stacked end portion and is exposed to the other side, and a rod-shaped connecting material 3, for example, is inserted into each horizontal hook portion 2a seen from the other side.
are inserted in a so-called bar shape, and the connecting ends are sandwiched and connected by the cooperation of the connecting band plate 2 and the connecting member 3.

In addition, when using a rope as the connecting material 3, it is inserted in a bar-like manner in the same way as the rod-shaped material described above, but the rope is entwined with the horizontal hook part 2a at appropriate intervals, and the rope and the connecting plate 2 are intertwined at appropriate intervals. may be fixed.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a connecting device for a network board according to the present invention will be described below with reference to FIGS. 1 to 4.

As shown in Fig. 1, the net board 1 to be connected is made of resin biaxially stretched into a mesh shape, and can maintain the required three-dimensional shape even when used alone as a molded product, and can be used as required at the construction site. It is necessary to have appropriate mechanical strength and flexibility, such as appropriate rigidity, so that the shape of the embankment or constructed soil can be constructed.
Further, the net board 1 is formed into a long roll shape with a constant width 1a, and is cut into a required length as necessary for use.

FIG. 2 shows a tie strip plate 2, which is formed into a ladder shape as shown, and the resin used is the same as that of the net plate 1. As shown in FIG. The cross-sectional shape of the connecting strip plate 2 is approximately U-shaped or approximately V-shaped. That is, a pair of parallel vertical hook parts 2b, 2b having a predetermined length are provided, and the horizontal hook part 2 is arranged so as to cross vertically and laterally in an arch shape to the left and right vertical hook parts 2b, 2b.
It has a structure in which both ends of the hooks 2a are connected and a plurality of horizontal hooks 2a are arranged at equal pitches.

Further, as shown in FIG. 3, a straight pipe-shaped or straight rod-shaped connecting material 3 is separately prepared in a fixed length, and this connecting material 3 has an outer diameter that is large enough to engage with the inner surface of the top of the horizontal hook portion 2a. It is rigid and flexible enough not to bend excessively.

Using each of the above members, as shown in Fig. 4,
For example, when constructing a reclaimed land by connecting a plurality of regular-sized net boards 1 to each other in order to correspond to the shape of embankment or reclaimed land, the connecting ends of two adjacent net boards 1 are overlapped and connected to each other. The meshes 1a in the same row direction are overlapped so that they are aligned. The horizontal hook portions 2a of the connecting strip board 2 are inserted from one side of the overlapped end so as to be exposed to the other side, and each of the horizontal hook portions 2a of the connecting strip board 2 seen on the other side is provided with a separately prepared joint. Insert material 3. That is, the joint strips 2 and the joint material 3 work together to sandwich the connecting ends in a bar-like manner to connect two adjacent net boards 1.

FIG. 5 and FIG. 6 are diagrams showing other embodiments. The connecting strip plate 2 shown in FIG. 5 has a wedge-shaped cross section. Therefore, as shown in FIG. 5, when the connecting ends of two adjacent net boards 1a are overlapped and locked with the connecting strip board 2 as in the previous embodiment, the vertical hook portion The wedge-shaped part 2b is fitted into the mesh 1a of the net board by utilizing the flexibility of the material, and once fitted, the wedge-shaped part serves as a stopper, making it difficult for the connecting strip board to come off the mesh.

[Effect of idea]

As explained above, when connecting net boards using the connecting tool according to the present invention, the connection ends of two adjacent net boards are overlapped, and then the horizontal hooks of the connecting strips are connected. Insert it into the mesh,
The connection is completed simply by inserting the connecting material in the shape of a bar through the horizontal hook, making the connection much easier and faster than conventional connection methods.
