Claims

[Claims for Utility Model Registration] 1. A joint made of synthetic resin having a long cylindrical body with a constant inner shape and dimensions, a base and a plurality of rod-shaped protrusions protruding from the base, the protrusions is solid and has a substantially uniform cross-sectional shape and dimensions adapted to the shape and dimensions of the inner surface for insertion into the cylinder. 2. The three-dimensional framework structure according to claim 1, wherein the protruding portion is solid. 3. The three-dimensional framework structure according to claim 1 or 2, wherein the base is solid. 4. Any one of claims 1 to 3, wherein the base has a polyhedral shape, and each of the plurality of protrusions protrudes from a surface constituting the polyhedron at a right angle to the surface. Three-dimensional framework structure described in crab. 5. The three-dimensional framework structure according to claim 4, wherein the cross-sectional area of the protrusion is smaller than the area of the surface from which the protrusion protrudes. 6. The three-dimensional framework structure according to any one of claims 1 to 5, wherein the side surface of the protrusion is substantially smooth. 7. The three-dimensional framework structure according to any one of claims 1 to 6, wherein a protruding strip extending in the longitudinal direction is provided on the inner surface of the cylindrical body.
