Abstract

PURPOSE: To extremely facilitate mutual coupling of spherical blocks and to increase stability of coupled bodies to minimize resistance against waves, by providing bolt holes for coupling at specified positions on spherical blocks.
CONSTITUTION: Circular hole 2 is provided on hollow porous half spherical wall body 1 toward sphere center. One piece of this hole 2 is provided on top portion of half spherical body, six pieces of them being provided at same interval in adjacent to connecting face 5, which is end face of half spherical body, totalling seven pieces being provided. And, two pieces of these half spherical bodies are connected at connecting face 5, bolt 6 is penetrated through hole 3, both ends are tightly connected and spherical block a having bolt hole 4 is formed, while in case three pieces of these blocks a are intended to be coupled holes 4 on three blocks a are faced with each other, through which bolt 7 is penetrated, both ends are tightened thereafter, tripled coupling bodies of spherical block a are then be assembled easily.
