COLUMN AND BEAM CONNECTION STRUCTURE AND METHOD

摘要

[Problem] To provide a column and beam connection structure that has excellent stress transmission performance during earthquakes and that allows mounting to columns without welding to external diaphragms, and a column and beam connection method. [Solution] A column and beam connection method to join a steel H-beam 3 to a steel pipe column 5 using an external diaphragm 1, wherein a beam plate 22 on a split diaphragm 2, which is a section of the external diaphragm 1 that is split into a plurality of sections, is mounted to a flange 31, 33 on the steel H-beam 3 and a column plate 23 provided on an end of the beam plate 22 is caused to abut the steel pipe column 5. By disposing the joining face between split diaphragms 2 near a corner 5a of the steel pipe column 5, each column face of the steel pipe column 5 abuts only the column plate 23 on one split diaphragm 2. The split diaphragms are anchored by tightening bolts 25 and nuts 26 so that the contact pressure acts from the column plate 23 to the column face of the steel pipe column 5.
