Description

[Detailed description of the invention] (Industrial application field) The present invention is a 26-hedron connected type block in which three 26-hedrons whose faces intersect at 135 degrees are connected in a chevron shape.
This relates to a joining structure that connects a plurality of pieces.

(Prior art) This 26-hedral articulated block has excellent wave-dissipating properties and is expected to be used as wave-dissipating structures on coastlines and sea walls.

(Problem that the invention aims to solve) The 26-hedron connected type block is used with n (n≧2) basic units installed in parallel, but in locations where wave power or tidal power is excessive, each basic unit is If the units are in an isolated state where they are not connected to each other, it is conceivable that the blocks will tilt or overturn over time, reducing the intended wave-dissipating effect.

Therefore, the purpose of the present invention is to provide a joint structure that can interconnect a plurality of basic units easily and efficiently, and that can accurately obtain a bonding strength that is sufficient to resist excessive wave force and tidal force. It is.

(Means for Solving the Problems) As explained below using the reference numerals in the attached drawings, the 26-hedral connected type block to which the joint structure of the present invention is applied, connects each side of a cube to the corresponding side. Intersect at right angles to the plane formed by adjacent sides perpendicular to
It is obtained by cutting at the cutting plane that intersects at 3, and by removing a triangular pyramid whose edge is the line where the three mutually perpendicular cutting planes intersect, and whose base side is √2/3 of the side of the cube. In addition, it is made of 6 square faces, 8 equilateral triangular faces, and 12 rectangular faces, and is made by integrally molding three 26-sided faces that intersect at an angle of 135 degrees, connected in a chevron shape. , one side of the square is 1/3 of one side of the cube, and the long side of the rectangle is √2/3 of one side of the cube.
The short side of the rectangle is 1/3 of the side of the cube, and the side of the equilateral triangle is √2/of the side of the cube.
It is 3.

In the case of a third icosahedron C, a metal pipe 2 is embedded through the center of the front right middle trunk rectangular surface 1a and the center of the rear left middle trunk rectangular surface 1b of the first icosahedron A. In addition, a connecting icosahedron in which a metal pipe 2 is embedded through the center of the right middle trunk rectangular surface 1a on the front side of the third icosahedron C and the center of the left middle trunk rectangular surface 1b on the rear side. The basic unit is the mold block, and the rear left middle trunk rectangular surface 1b of the first icosahedron A of the front basic unit and the first icosahedron A of the rear basic unit
The front right middle trunk rectangular surface 1a is brought into contact with the
Further, the left middle trunk rectangular surface 1b on the rear side of the second icosahedron B of the front basic unit is brought into contact with the right middle trunk rectangular surface 1a on the front side of the second icosahedron B of the rear basic unit, Then, the left middle trunk rectangular surface 1b on the rear side of the third icosahedron C of the front basic unit and the third 26 of the rear basic unit.
A metal rod 3 with threaded portions 3a provided at both ends is inserted into the metal pipe 2 by bringing the front side of the face piece C into contact with the rectangular surface 1a of the right middle part of the body, and tightening the nut 4 screwed into the threaded portion 3a. It connects n basic units (n≧2).

(Function) A plurality of basic units are arranged in a row in front and back, and the left middle trunk rectangular surface 1b on the rear side of the first icosahedron A of the front basic unit and the right middle of the front side of the first icosahedron A of the rear basic unit. The left middle trunk rectangular surface 1 on the rear side of the second icosahedron B of the front basic unit is in contact with the trunk rectangular surface 1a.
b and the front right middle trunk rectangular surface 1a of the second icosahedron B of the rear basic unit, and the left middle trunk rectangular surface 1b of the rear side of the third icosahedron C of the front basic unit. and the front right middle trunk rectangular surface 1a of the third icosahedron C of the rear basic unit, and the metal pipe 2 of the front basic unit and the metal pipe 2 of the rear basic unit are connected to each other or relative to each other. The metal rod 3 is inserted into each metal pipe 2 with the metal rod 3 facing the same direction.

The right middle trunk rectangular surface 1a on the front side of the first icosahedron A and third icosahedron C of the front basic unit and the left middle trunk of the rear side of the first icosahedron A and third icosahedron C of the rear basic unit. Each screw portion 3 of the metal rod 3 protruding from the rectangular surface 1b
Screw nut 4 onto a. By tightening each nut 4, the middle trunk rectangular surface 1b on the rear side of the front basic unit
The front middle trunk rectangular surface 1a of the rear basic unit is brought into close contact with the rear basic unit, thereby completing the interconnection of the plurality of front and rear basic units.

(Embodiment) In the illustrated embodiment, the metal pipe 2, metal rod 3, and nut 4 are all made of metal or ceramic materials with excellent corrosion resistance and mechanical strength, and are coated with anti-corrosion paint as necessary. A coating is applied.

When the metal rod 3 is inserted into the metal pipe 2, a rust inhibitor is filled between the metal pipe 2 and the metal rod 3. Grooves 3b are provided on both end faces of the metal rod 3 into which a tool is inserted to prevent the metal rod 3 from rotating when the nut 4 is tightened.

(Effects) As described above, the joining structure of the icosahedron connected type block of the present invention is that the center part of the rectangular face 1a of the front right middle part of the first icosahedron A and the third icosahedron C, and the left middle part of the rear side. A metal pipe 2 is embedded through the center of the rectangular surface 1b of the body, and nuts 4 are screwed into the threaded portions 3a at both ends of the metal rod 3 inserted through the metal pipe 2.
Since the nut 4 is tightened to bring the rear middle trunk rectangular surface 1b of the front basic unit into close contact with the front middle trunk rectangular surface 1a of the rear basic unit, multiple basic units can be worked efficiently. They can be easily interconnected and provide a precise bonding strength that is sufficient to resist excessive wave and tidal forces.
