STEEL-FRAMED BEAM HAVING JOINT JOINED RIGIDLY BY HIGH- STRENGTH BOLT

摘要

PROBLEM TO BE SOLVED: To provide a structure for making a steel-framed beam joined rigidly by a high-strength bolt, which suppresses an increase in weight, has adequate strength and rigidity, and facilitates not only transportation but also execution of work. SOLUTION: An end of the steel-framed beam is rigidly joined by only the high-strength bolt.
