1 to 4 show a first embodiment of the externally mounted damping damper system 10 of the present invention. Referring to the drawings, the externally mounted damping damper system 10 is mounted on the outer wall of the building structure 1.

The horizontal frame 14 is fixed to the beam 6 of the building structure 1 and extends in the horizontal direction along the beam 6. The vertical frame 15 extends downward along the column 5 from both lower ends of the horizontal frame 14. In addition, the coupling frame 16 extends to interconnect the lower ends of the two vertical frames 15 and extends in parallel with the base frame 12 at a predetermined interval. In particular, the coupling frame 16 is preferably installed to pass through the lower waist wall 4 of the window 7 of the building structure (1).

Preferably, the horizontal frame 14, the vertical frame 15, and the combined frame 16 are all formed of H beams.

The damper 100 is installed between the coupling frame 16 and the base frame 12 to attenuate an external force applied along the longitudinal direction of the base frame 12.

Referring to FIGS. 3 and 4, the damper 100 includes the first and second supports 110 and 120, an additional plate 130 connecting the first and second supports 110 and 120, and the first support 110. The friction plate 140 provided between the adding plate 130 and a fastening portion 150 for coupling them to each other.

The first support 110 has a first end plate 111 fixed to the coupling frame 16, and a sliding plate 114 extending downward from the first end plate 111.

A plurality of fastening holes 112 penetrating the upper and lower surfaces are formed in the first end plate 111, and fastening is performed through the fastening members 60.

The sliding plate 114 extends downward from the lower surface of the first end plate 111 by a predetermined length. The sliding plate 114 is formed to have a 'T' shape when viewed from the side. Two long holes 115 penetrating the front and rear surfaces and extending a predetermined length along the horizontal direction are formed in the sliding plate 114 to be spaced apart from each other by a predetermined distance in the horizontal direction.

The second support 120 includes a second end plate 121 fixed to the base frame 12 and an extension 123 extending upward from an upper surface of the second end plate 121. A plurality of fastening holes 122 are formed in the plate 121 so that the fastening members 60 may be mounted, and the extension part 123 may have an upper surface of the second end plate 121 so as to have an inverse 'T' shape. It extends upward from the center.

Accordingly, the first and second support members 110 and 120 may have sliding plates (1, 2, 3, 4, 4) in which the first and second end plates 111 and 121 are respectively supported by the coupling frame 16 and the base frame 12 and face each other. 114 and the extension part 123 are extended.

The additional plate 130 has coupling holes 132 corresponding to the shape of the coupling protrusion 124 so that the coupling protrusions 124 may be fitted therein.

The first bolting hole 131 is formed on the coupling holes 132 to allow the tension bolt 151 of the fastening part 150 to pass therethrough.

Although the coupling protrusion 124 is illustrated as being formed in a cylindrical shape having a predetermined diameter in this embodiment, the extension plate 123 extends along the pillar shape or the longitudinal direction in addition to the extension part 123 if it can be connected. It may be formed in the shape of an elliptic cylinder having an elliptical cross section.

The friction plate 140 is to attenuate the external force applied to the building structure by providing a frictional force when the first support 110 is slid in the horizontal direction with respect to the second support 120 by the external force.

The friction plate 140 is mounted to be positioned between the front and rear surfaces of the sliding plate 114 and the backing plate 130, and second bolting holes 141 corresponding to the first bolting holes 131 are formed. In addition, the fastening part 150 is fixed between the sliding plate 114 and the adding plate 130.

When the friction plate 140 moves in a horizontal direction so that the external force is attenuated when the sliding plate 114 is vibrated, vibration energy applied from the outside may be dissipated into thermal energy by generating frictional heat in contact with the sliding plate 114. It is intended to be, it is preferably formed of a material having a relatively small hardness compared to the sliding plate (114).

When the friction plate 140 is made of a material having a relatively low hardness compared to the sliding plate 114, when the friction plate 140 and the sliding plate 114 is in continuous friction contact, the friction plate 140 is worn and the thickness is increased. Increasingly, the sliding plate 114 can be used relatively long without deformation.

Since the replaceable friction plate 140 has a material that can be relatively easily worn, the vibration damping force of the damper 100 can be maintained at an appropriate level through the exchange of the friction plate 140.

In the present embodiment, both the sliding plate 114 and the friction plate 140 has a contact surface formed in the form of a smooth surface, but the sliding plate 114 and the friction plate 140 may be mutually coupled to expand the friction area. It may be formed to have.

The fastening part 150 is for fastening the sliding plate 114, the friction plate 140, and the back plate 130, and includes a tension bolt 151, a nut 152, and a washer member 153.

As described above, first and second bolting holes 131 and 141 are formed in the back plate 130 and the friction plate 140, respectively, and a long hole 115 is formed in the sliding plate 114.

After inserting the washer member 153 to the tension bolt 151, one side of the back plate 130 and the friction plate 140, the sliding plate 114, the other side of the friction plate 140 and the back plate 130 in order to pass through and then tension Insert the washer member 153 again on the other side of the bolt 151 and fasten with the nut 152.

The damper 100 has a different magnitude of vibration depending on the magnitude of the frictional force between the friction plate 140 and the sliding plate 114. That is, in the case of a strong earthquake, since the magnitude of vibration is large, the friction plate 140 and the sliding plate 114 must be fastened so that the frictional strength is large, and thus the damping effect of the vibration can be obtained. For a relatively small vibration, the frictional force must be small to reduce vibration energy while slip occurs between the friction plate 140 and the sliding plate 114.

Therefore, in consideration of various requirements such as the purpose or installation position of the building structure 10, the appropriate frictional strength is set, and the tension bolt 151 is tightened with a torque wrench to set the friction between the friction plate 140 and the sliding plate 114. It is desirable to have a bearing force present.

The washer member 153 is a plate spring washer was applied, if the slip continuously occurs between the friction plate 140 and the sliding plate 114 by vibration, eventually the friction plate 140 is worn, the thickness of the friction plate 140 As a result, as the fastening force of the tension bolt 151 is lowered, the frictional force between the friction plate 140 and the sliding plate 114 may not be maintained at an initially set value.

When the frictional force is reduced, the functionality of the damper 100 is reduced, so that the frictional force between the friction plate 140 and the sliding plate 114 can be maintained even when the friction plate 140 is worn through the washer member 153. 153 is preferably a dish spring washer.

In the present embodiment, the damper 100 is applied as a friction damper 100, but various types of damping devices such as steel damper 100 may be applied.
