Mechanical structure and outer frame

Abstract

The objective of this invention is to provide a mechanical structure and an outer frame comprising such a mechanical structure, the mechanical structure having strength exceeding that of natural stone and comparable to that of castings, exhibiting greater attenuation than natural stone, and possessing excellent durability and dimensional accuracy. The mechanical structure system of this invention is used for main structures such as bases or columns, and comprises: a first structure made of metal; and a second structure made of a high-attenuation material, cast in contact with at least a portion of the outer surface of the first structure; and the first structure having an exposed portion protruding from the surface of the second structure.
