Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device for connecting concrete blocks or the like arranged in parallel to each other, and more particularly to a connecting device mounted between anchors attached to the concrete blocks or the like. The present invention relates to a connecting device for fixing members to be joined.

[0002]

2. Description of the Related Art In recent years, on a riverbed, a concrete block with natural stones is placed on the surface of the riverbed to create rivers, pools, rocks, etc. where fish can easily inhabit. Improvements in habitat are being done. An anchor 2 is attached to each of the concrete blocks 1 as shown in FIGS. 6 and 7. Then, connect the U-shaped connecting fittings 3 to the respective anchors 2.
2 and the bolts 4 and nuts 5 are attached to the hole 3a at the tip of the connecting fitting 3 to connect the two concrete blocks 1.

[0003]

In the above structure, since there is a gap between the anchor 2 as the member to be connected and the connecting fitting 3, the two concrete blocks 1 are not securely fixed, and the external force is not fixed. When is added, there is a problem that they move by the amount of the gap.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a connecting device capable of reliably fixing a plurality of members to be connected.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a pair of connecting members having a tightening screw portion and an insertion hole formed at a distance from the tightening screw portion are opposed to each other with a member to be joined therebetween, and one of them is connected to the other. Insert the tightening screw part of the connector into the insertion hole of the other connector,
It is characterized in that a nut is screwed into the tightening screw portion to press and fix the member to be coupled.

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of a connecting device 10 of the present invention will be described below with reference to FIGS. However, the same parts as those in the conventional example are designated by the same reference numerals. A U-shaped anchor 2 as a member to be connected is embedded in the concrete block 1. The two concrete blocks 1 are arranged adjacent to each other so that the respective anchors 2 face each other.

The pair of connecting members 11A, 11B are formed from, for example, a wire material into an L-shape, and one of them has a tightening screw portion 12A, 1B.
2B is formed. Further, the tightening screw portions 12A, 12
The end portion of B is bent in a ring shape at a substantially right angle, and insertion holes 13A and 13B are formed therein. This insertion hole 13
A and 13B are formed in a size into which the tightening screw parts 12A and 12B can be inserted, and at least two anchors 2 are sandwiched between the insertion holes 13A and 13B and the tightening screw parts 12A and 12B. Set to distance. The connector is
The plate member and the bolt may be combined to form the insertion hole 13.
The shapes of A and 13B are not limited to circular shapes and may be polygonal shapes. The number of members to be coupled may be three or more.

As shown in FIG. 1, the pair of connecting members 11A and 11B are inserted into the anchors 2, respectively, and the tightening screw portions 12A and 12B are arranged to face each other. Therefore, the tightening screw portion 12A is inserted into the insertion hole 13B, and the tightening screw portion 1
2B is inserted into the insertion hole 13A. As a result, the two anchors 2 are sandwiched between the pair of connecting tools 11A and 11B. Then, the washer 14 is inserted into the tightening screw parts 12A and 12B, and the nuts 15 are screwed into the tightening screw parts 12A and 12B. When the nut 15 is tightened, as shown in FIG. 3, the anchor 2 is pressed against the connecting tools 11A and 11B and pulled toward each other in the direction of the arrow to be pressed and fixed. That is, the concrete blocks 1 are integrally fixed to each other and do not move even if an external force is applied, for example, even if the flow rate of the river increases.

In the above embodiment, the connecting tool 11 is used.
By tightening A and 11B, the concrete block 1 is moved and the two anchors 2 are in contact with each other. However, in order to fix the concrete blocks 1 to each other, the connector 1
It is sufficient that 1A, 11B and the anchor 2 are pressed against each other, and there may be a gap between the anchors 2.

According to the above embodiment, the following effects can be obtained. (1) Since the connecting device 10 is composed of the pair of connecting tools 11A and 11B, the number of types of parts can be reduced, and parts management is easy. (2) Since the fixing work is performed by inserting the one tightening screw portion 12A, 12B into the other insertion hole 13B, 13A with the anchor 2 interposed therebetween and screwing the nut 15, the anchor 2 is not arranged. Even if it is a rule, assembly and fixing work can be done easily. (3) Since the concrete blocks 1 are integrally fixed to each other, the positional displacement does not occur even if an external force is applied.

FIG. 4 shows another embodiment of the present invention.
The difference from the above-mentioned embodiment is that the nut 15 is tightened with a tightening screw portion 12A.
It is screwed only to. This embodiment also has the same effects as the above embodiment.

FIG. 5 shows a second embodiment of the present invention. The difference from the first embodiment is that the end portions of the tightening screw portions 22 of the pair of connecting members 21 are U-shaped. The insertion hole 23 is formed by bending and further bending the tip end in a ring shape at a substantially right angle. The second embodiment has an effect that the anchors 2 can be easily coupled even when the distance between them is large.

[0013]

According to the present invention, a pair of connecting tools having a tightening screw portion and an insertion hole formed at a distance from the tightening screw portion are opposed to each other with a member to be joined interposed therebetween, and one connecting tool is tightened. The attached screw part is inserted into the insertion hole of the other connecting tool, and the nut is screwed onto the tightening screw part to press-connect / fix the member to be joined, so that the same part can be used, and part management can be performed. It has an excellent effect that it is simple and that the assembling and fixing work can be carried out easily and surely.
