FRICTION DAMPER MECHANISM
To provide a friction damper mechanism that generates a small friction force during a medium to a small earthquake in which the axial displacement of a damper is small, and generates a large frictional force during a large earthquake in which the axial displacement of the damper is large.SOLUTION: A friction damping mechanism comprises a first friction damping device 1 and a second friction damping device arranged in parallel with each other. The first friction damping device 1 comprises: a first upper connecting plate 11; a first lower connecting plate material 12 arranged coaxially with and axially apart from the first upper connecting plate material 11, connected to the lower structure, and formed so that the thickness in the vertical direction gradually increases as it approaches the first upper connecting plate material 11; a first upper side plate material 13; a first lower side plate material 14; first friction plate materials 15, 16; a first bearing part 17 for applying bearing pressure to the first lower connecting plate material 12 with the first upper side plate material 13 and the first lower side plate material 14; and a first movement restraining part 18 for restraining axial movement of the first upper connection plate material 11, the first upper side plate material 13 and the first lower side plate material 14.SELECTED DRAWING: Figure 2
