PROBLEM TO BE SOLVED: To provide a joint structure between a steel pipe pole using a multi-segment diaphragm and a steel beam of stable quality and inexpensive. SOLUTION: The diaphragm 2 consists of four multi-segment diaphragms 2a which are formed by dividing the diaphragm 2 into a plurality of diaphragms in the circumference of the steel pipe pole 1. The steel beam 3 is connected by welding to the multi-segment diaphragm 2a, and the multi-segment diaphragms 2a, 2a adjacent to each other are partial penetration welded (B). Thus, since there is no need to consider a cross-section loss in the diaphragm caused by a bolt hole, it does not result in an increase in the width of the diaphragm or the plate thickness of the diaphragm. Thus, a steep rise in material costs of the diaphragm or the like can be controlled, and the inexpensive joint structure of stable quality can be provided. COPYRIGHT: (C)2007,JPO&INPIT
