Title:
VIBRATION CONTROL DEVICE FOR BRACE AND BRACE
Document Type and Number:
Japanese Patent JP2019157478
Kind Code:
A
Abstract:
To suppress oscillation of wooden framework structure.SOLUTION: A vibration control device for brace includes: a holding part 22 which inserts and holds an end part side of a brace body 21 so as to relatively move in the longer direction of the brace body 21 and which is fixed to a side part of a column material via a fixture; a coming-off prevention part 23 formed at the end part of the brace body 21, and for preventing coming off of the brace body 21 by coming into contact with the end part of the column material side in the longer direction of the holding part 22 in an initial position of a frame structure; a fastening mechanism 24 formed at the holding part 22 and for increasing/decreasing a frictional force when coming into contact with the brace body 21 inside by input of rotation; and a conversion mechanism 25 for inputting the rotation in the fastening mechanism 24 according to a linear motion of the brace body 21. In the case where a compressive force is applied to a brace 12, the conversion mechanism 25 increases the fastening force by the fastening mechanism 24 according to the movement of the brace body 21 and creates a state where always a predetermined frictional force acts between itself and the brace body 21. The brace body 21 is moved in this state, vibration energy is dissipated, and vibration of the frame is suppressed.SELECTED DRAWING: Figure 4
