THE FRICTION DAMPER FOR THE EARTHQUAKE-PROOF

摘要

PURPOSE: A frictional damper for reinforcing earthquake resistance is provided to effectively damp force, which the connecting unit between frictional dampers as well as a frictional damper applies. CONSTITUTION: A frictional damper for reinforcing earthquake resistance comprises at least two frictional dampers(2), and a connecting unit(3). Each end of the frictional dampers is connected to the corner or surface of one section, which forms a square frame to reinforce the earthquake resistance of a steel frame or reinforced-concrete building. The connecting unit connects the other end of the frictional damper. The connecting unit comprises four long holes(31), first and second frictional plates(32a, 32b), two fixing bolts(33), and a nut(34). The long holes are formed on the end of one of the frictional damper in its length direction.
