The technical means of the present invention for solving such a problem is, in a polyhedron in which a ridge portion is formed by a frame, each polyhedron constituting surface constitutes a side of the polyhedron constituting surface. Configured with a frame body in which side bodies are connected,
The frames are formed by joining the side bodies of the respective frame bodies.

If necessary, the surface of the side body of the frame body is formed as a plane parallel to the polyhedron constituting surface, and the outer surface to which the side body is joined is formed at a predetermined angle between adjacent polyhedral constituting surfaces. Is formed on an inclined surface inclined with respect to the above surface. In this case, it is effective to adhere the outer surfaces of the side bodies of the adjacent frame bodies to each other with an adhesive.

Is formed on an inclined surface that is inclined with respect to the surface 12 so that the angle between the adjacent polyhedral structure surfaces M becomes a predetermined angle and that is joined to the outer side surface 14 of the adjacent side body 11. Cuboid 1
The inner side surface 15 of No. 1 is formed in a plane perpendicular to the surface 12. In addition, the end face 16 of the side body 11 is formed at an angle that is joined to the end face 16 of the adjacent side body 11 to form the polyhedral structure surface M.

In the present embodiment, FIG. 3 (a)
As shown in (b), a regular pentagonal polyhedral surface M (a)
The angle θ1 formed by the surface 12 of the side body 11 and the outer side surface 14 of the frame body 10 (a) having θ is θ1 = 73.5 degrees, and the frame body has a regular hexagonal polyhedral surface M (b). 10 (b)
Angle θ2 between the surface 12 and the outer surface 14 of the cuboid 11

Further, as shown in FIG. 3, adjacent frame bodies 1
The outer side surfaces 14 of the 0-sided body 11 are bonded to each other via only the adhesive 17. Further, as shown in FIGS. 1 and 2A, a reinforcing member 20 embedded in each side body 11 is provided at a continuous portion of adjacent side bodies 11 of the frame body 10. The reinforcing member 20 has the outer surface 14 between the adjacent side bodies 11.
It is configured by a wooden board fitted in a slit 21 formed so as to extend from the side.

Therefore, when manufacturing the polyhedron according to this embodiment, first, each frame 10 is manufactured. this is,
Front face 12, back face 13, outer face 1 of side body 11 of frame body 10
4, the inner side surface 15 and the end surface 16 are formed by cutting at a predetermined angle, and the end surface 16 of the side body 11 is joined by an adhesive. In addition, as shown in FIG. 2A, after joining, a slit 21 that straddles between the adjacent side bodies 11 is formed from the outer surface 14 side, and the wood board 2 is bonded to this slit 21 with an adhesive.
2 is fitted, and then the wood board 22 is cut along the outer side surface 14, and the wood piece remaining after fitting is used as the reinforcing member 20. Next, each frame body 10 is joined at a predetermined position. In this case, the outer side surfaces 14 of the adjacent side bodies 11 are bonded to each other via the adhesive agent 17. Thereby, the frame F is formed.

In the polyhedron thus formed,
Since the frame F is formed by joining the side bodies 11 of each frame body 10 to each other, the adjacent frame bodies 10 are side-supported as compared with the conventional point support, and the supporting strength is significantly increased. Be improved to. Therefore, even if an external pressure is applied, the polyhedral surface M is less likely to be deformed, and the polyhedral surface M is durable. In particular, the outer surface 14 to which the cuboid 11 is joined has the surface 12 such that the angles between the adjacent polyhedron constituting surfaces M become a predetermined angle.
Since it is formed on an inclined surface inclined with respect to
The ones are surface-bonded to each other to be surface-supported, so that the supporting strength is further improved. Further, since the adhesive 17 is interposed between the outer side surfaces 14, the bonding is ensured and
Since it does not depend on nails or bolts, the manufacturing is facilitated accordingly. Further, in this case, even if it is fixed only by the adhesive 17 without using nails or bolts, it can be fixed by surface bonding, so that it is possible to make it strong in strength.

Furthermore, since the reinforcing members 20 embedded in the side bodies 11 of the adjacent frame bodies 10 are provided at the connecting portions of the adjacent side bodies 11 of the frame body 10, the end faces of the side bodies 11 in each frame body 10 are provided. The joining between the 16 is also strong, and also in this respect, the supporting strength is significantly improved, and the deformation of the polyhedral structure surface M is prevented. Further, since the side body 11 of the frame body 10 and the reinforcing member 20 are made of wood, the entire body becomes light in weight, and the workability and the transportability are improved.

Since the frame is formed, the adjacent frame bodies are side-supported as compared with the conventional point support, and therefore the support strength can be significantly improved. As a result, even if an external pressure is applied, the surface of the polyhedron can be easily prevented from being deformed, and a strong structure can be obtained.

Further, the surface of the side body of the frame body is formed as a plane parallel to the polyhedron constituting surface, and the outer surface to which the side body is joined is formed on the surface so that the angle between the adjacent polyhedron constituting surfaces becomes a predetermined angle. In the case where it is formed on an inclined surface that is inclined with respect to each other, the side bodies can be surface-joined to each other, and thus each frame can be surface-supported, so that the supporting strength can be further improved. Further, since the surface of the side body of the frame body is formed as a plane parallel to the polyhedron constituting surface, the polyhedral constituting surface can be surely formed into a flat surface when attaching a paper or a plate. effective.

Further, when the outer surfaces of the side bodies of the adjacent frame bodies are adhered to each other via the adhesive agent, the adhesive agent intervenes between the side bodies, so that the connection is surely performed without using nails or bolts. In addition to being strong, it can be manufactured easily.

Furthermore, when reinforcing members embedded in the side bodies of the adjacent side bodies of the frame body are connected to each other, strengthening the joint between the side bodies in each frame body. Can
