PURPOSE: To prepare a rock-work stair easily in a short time without particularly requiring a masonry and a plasterer craftsman regarding a stair preparation method on a ground surface and forms and a stair material. CONSTITUTION: A plurality of stones 5 are arranged on the bottom of stair- material forms with a bottom constituted of two inlined planes crossed at approximately right angles. Concrete materials are placed on the stones 5, and stair materials 8, in which the stones 5 are exposed from fronts and top faces, are prepared. An inclined foundation bed 10 is created on an inclined ground surface. The stair materials 8 are arranged successively onto the inclined foundation bed 10 from lower sections. The stair materials 8 are fixed onto the inclined foundation bed 10. The stair material, in which flat stones are piled up in wooden ends, is obtained when stone supporters are arranged on a small inclined plane at regular intervals in the vertical direction in stair- material forms. |
