Beam Connecting Type Friction Damper and Earthquake-proof Method using thereof
The present invention relates to a beam connecting type friction damper which is capable of effectively damping a lateral force concentrated on a column of a building to be reinforced when an earthquake occurs as a structure connecting parallel upper and lower beams. The present invention includes an upper friction plate (110); an upper beam attaching piece (120) coupled to the upper end surface of the upper friction plate (110) at right angles and having a plurality of anchor bolt installation holes (55) to be attached to a lower surface of the upper beam; a lower friction plate (210); a lower beam attaching piece (220) coupled to the lower end surface of the lower friction plate (210) at right angles and having a plurality of anchor bolt installation holes (55) to be attached to an upper surface of the lower beam; and a friction coupling plate (310) coupled by an upper hinge pin (320) to be overlapped with the upper friction plate (110) in the upper end portion and coupled by a lower hinge pin (330) to be overlapped with the lower friction plate (210) in the lower end portion. Each of the upper friction plate (110) and the lower friction plate (210) is provided with an arc cut-out portion (77). The frictional force is enhanced between the friction coupling plate (310) and the upper friction plate (110) and between the friction coupling plate (310) and the lower friction plate (210) by a fastening bolt (11) nut (22) fastened through the fastening bolt through hole (66) and the arc cut-out portion (77) formed in the upper and lower end portions of the friction coupling plate (310).
