Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block connecting method characterized in that, for example, annular parts projecting from the ends of four blocks are connected by one connecting metal fitting. is there.

[0002]

2. Description of the Related Art Conventionally, as a method of connecting revetment blocks, the connecting iron wires projecting from the ends of the blocks are superposed on each other and entangled, or the reinforcing bars protruding from the ends are welded. When the annular portion projects from the end, the opposing annular portion is fastened with a shackle.

[0003]

As described above, when the connecting iron wires protruding from the end of the block are entangled by being polymerized with each other, if the iron wires are too thick, it is difficult for them to be entangled manually. Further, when reinforcing bars are welded, only one side can be welded, so the strength is weak and the connection method is unreliable. Furthermore, if there are many welding points, it is not efficient in terms of efficiency and is not liked by workers, and the reinforcing bars embedded inside the block project from the end of the block into an annular part,
The best way is to pull this with a shackle and fasten it, but if there are 3 to 4 annular parts, it is difficult to fasten it with one shackle, and you can also use two shackles to fasten it. there were. If this is done, the cost of connecting metal fittings per location will be high, which is uneconomical. Also,
The method of fastening with a shackle is relatively easy when the annular portion is projected vertically, but it is difficult to secure with a single shackle when the annular portion is projected horizontally.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to provide a method for connecting four annular portions protruding from the four corners of a block together at the same time. Is a notched inclined side surface, and the reinforcing bar embedded inside is protruded in a U shape from the inclined side surface to form an annular portion, and the inclined side surfaces of such four main bodies are abutted to each other, and the middle of the U-shaped connecting metal fitting is formed. Is bent in parallel in a curved shape when viewed from the side to form a bent portion, which is first inserted into the two annular portions,
Then, it is inserted into the remaining two annular portions, and the two through holes of the plate are inserted into the free ends of the U-shaped connecting fittings to tighten the nuts. With such a configuration, the four annular parts arranged on the plane can be all connected by one connecting fitting, and the installation can be performed easily and efficiently, and at a low cost. is there.

[0005]

Embodiments will be described with reference to the drawings. Reference numeral 1 is a plate-shaped or block-shaped block formed of concrete or the like. Reference numeral 2 designates the four corners of the main body 1 as notches to form inclined side surfaces. 3 is a reinforcing bar embedded inside the main body 1,
It is an annular portion formed in a U shape projecting from the inclined side surfaces 2 at the four corners. Reference numeral 4 denotes a connecting fitting, which is formed in a U-shape, and a middle portion of which is bent in a curved shape in parallel to form a bent portion 5. 6 is a plate, which is a connecting fitting 4
A through hole 7 is formed corresponding to the distance between the free ends. The slanted side surfaces 2 of the four main bodies 1 configured as described above are butted together, and one connecting fitting 4 is first inserted into the annular portion 3 of the two main bodies 1, 1 and then the remaining two main bodies 1, 1. Annulus 3 of 1
The through hole 7 of the plate 6 is inserted into the free end of the connecting fitting 4, and the nut 8 is tightened to be attached.

[0006]

Since the present invention has the above-mentioned structure, the main body 1
If the square shape is square, the corners of the four main bodies 1 are butted together, first the two free ends of the connecting metal fitting 4 are inserted into the annular portions 3, 3 of the two main bodies 1, 1 and then the remaining two The connecting fittings 4 are inserted into the annular parts 3 and 3 of the main bodies 1 and 1 while rotating, and the through holes 7 of the plate 6 are inserted into the two free ends of the connecting fittings 4 and the nuts 8 are tightened to be attached. It is a thing.

[0007]

According to the present invention, the connecting members 4 are connected to the four annular portions 3.
To insert the plug, first insert the connecting fitting 4 into the two annular parts 3 and 3.
The free end of the is inserted while rotating, and then the remaining two annular parts 3 and 3 are inserted, but it is easy because the connecting metal fitting 4 is a curved bent part 5 when viewed from the side. Even if the four annular parts 3 are arranged on a plane, they can all be connected by one connecting fitting 4, and the insertion into the annular part 3 is easy and strong. And is economical. In addition, the connection of each block is a hinge, so it can move freely and can sufficiently follow the bending of the block, the block can well adhere to the ground and fulfill its mission, forming a strong revetment It has an effect that can be achieved.
