POLE-BEAM JUNCTION STRUCTURE

PURPOSE: To provide a pole-beam junction structure whose work execution cost is low with simple structure and also which has large resistance and excellent energy absorptive performance, in a junction structure between a reinforcing rod concrete pole and a steel beam. CONSTITUTION: A plurality of steel beams 1 to be joined with one another on roughly the same level as the side face of a reinforcing rod concrete pole 2 are joined with one other within the pole. In each segment of the pole members made by division with these steel beams 1, a spiral loop rod 4 is arranged to surround the main reinforcing rod 3 of the pole arranged in that section. Moreover, band plates 4 are arranged in the vicinity of the upper flange 11a and in the vicinity of the lower flange 11b of the beam, and they are joined to the end plate 13 fixed to the steel beam 1. Hereby, the band plate 14 becomes continuous to surround the whole of the pole together with the end plate 13. Furthermore, a nut 6 is screwed to the main rod 3 of the pole 2, and the steel beam is fastened from above and below to restrain the displacement of the main reinforcing rod 3.
