PURPOSE:To form a light-weight block main body, by a method wherein building stones in various shapes are laid in a state of a plane into a form having a bottom part, a molding material for a joint is interposed among the building stones, then synthetic resin such as urethane rubber is cast into the form, a block body is demolded from the form after cure and a gap part of the joint is formed beautifully. CONSTITUTION:A boxlike form 1 having various dimensions and depths is formed of a metal provided with a bottom part. Building stones 2 such as natural stones such as cobblestone, pyroxene andesite or a granite and artificial stones or imitation stones such as bricks or tiles are spread all over the bottom part of the form 1 at appropriate intervals. Molding material 3 for a joint comprised of various constituent materials is interposed among the building stones 2 spread all over the form 1. Then a reinforcement material 5 such as mesh steel is laid as a core material at need. Then urethane rubber 6 in a molten state is cast and filled in order into the building materials 2, 2, the molding materials 3, 3 for the joint and the reinforcement materials 5 within the form 1. |
