<P>PROBLEM TO BE SOLVED: To improve vibration control effects of a vibration control device provided in a joint of a wooden framework. <P>SOLUTION: A metal damper 180 is deformed by an external force of earthquake or the like, so that energy is absorbed and vibration is controlled. A fixed part 160A is fixed by a bolt 20 which vertically holds and vertically penetrates a batten 10, and a fixed part 160B is fixed by a bolt 20 which horizontally holds and horizontally penetrates a column 12. Therefore, even if a large load is applied iteratively in a direction where the fixed parts 160 are pulled out of the batten 10 and the column 12, deviation or removal is prevented or suppressed. Further, projections 163 formed by folding terminal parts of a first fixed plate 162 and a second fixed plate 164 in the fixed parts 160 are engaged into the batten 10 and the column 12, thereby preventing or suppressing deviation or removal in a direction along with the batten 10 and the column 12. Moreover, the deviation of the fixed parts 160 caused by moving a shank of the bolt 20 a little for a gap between a through hole 16 and a through hole 166 is prevented or suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
