SOLID SUPPORTING MECHANISM MADE UP OF RAIL AND COMBINATION BODY

摘要

Three-dimensional structures are made of open or closed profile structural beams, said beams being connected perpendicularly to each other at all multiple joints and joined by an end face plate of said beams with cubic multiple joints. Such three-dimensional structures possess extremely good bearing property, said bearing capacity amounting to two and a half times its elastic limit so that these structures can compete economically with three-dimensional truss structures.
