Description

[0001] DAMPER FOR EARTHQUAKE-RESISTANT OF WOODEN STRUCTURE AND CONSTRUCTION METHOD FOR THE SAME [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anti-vibration damper technique, and more particularly, to an anti-vibration damper and a damper construction method installed on a wall of a wooden structure.

In recent years, earthquakes more than 4.0 magnitude are occurring in Korea, and the importance of seismic design of structures is increasing. An earthquake is a phenomenon in which the earth 's energy is shaken as the energy inside the earth comes out to the surface, and it can act as a load on the structure. Here, the load acting on the structure due to the ground motion due to the earthquake can be referred to as "earthquake load ". Seismic loads can act either horizontally or vertically on the structure and can be concentrated on specific layers or specific members of the structure. Therefore, the members constituting the structure should have ductility to cope with the rigidity to withstand the earthquake load and the shaking due to the earthquake.

A stiffener (e.g., an X-shaped stiffener, a brace, etc.) may be installed on the structure to improve the stiffness of the structure, and a damper may be installed on the structure to improve the ductility of the structure. The seismic performance of the structure can be improved when the stiffener and the damper are installed on the structure, but the construction cost and the construction period of the structure may be increased. Therefore, an effective method for improving the seismic performance of the structure will be needed.

In addition, the wall of the structure 100 may be formed of columns 110-1, 110-2, 110-3 and beams 120-1, 120-2. For example, the walls of the structure 100 can be formed by joining the pillars 110-1, 110-2, and 110-3 to the upper beam 120-1 and the lower beam 120-2, respectively . The pillars 110-1, 110-2 and 110-3 in the structure 100 may be joined to the beams 120-1 and 120-2 by screws (or anchor bolts, pins, etc.) .

On the other hand, when an earthquake occurs, an earthquake load can be applied to the structure 100. For example, an earthquake load may be applied to the walls of the structure 100 (e.g., columns 110-1, 110-2, 110-3, beams 120-1 and 120-2). The walls of the structure 100 can withstand seismic loads when the walls of the structure 100 have sufficient rigidity and ductility. However, when the wall of the structure 100 does not have sufficient rigidity and ductility, deformation may occur in the wall of the structure 100, and thus the structure 100 may collapse. In order to prevent such a problem, an anti-dust damper may be installed on the wall of the structure 100. The damper for damper may be constructed as follows.

5 is a front view showing a first embodiment of a structure provided with an anti-vibration damper.

Referring to Figure 5, the damper # 1 (400) for dustproofing is installed on the upper part of the wall of the structure 100 (i.e., the upper beam 120-1, the column # 1 110-1, And the damper # 2 500 for dustproofing can be installed in the lower part of the wall of the structure 100 (i.e., the lower beam 120-2, the column # 1 110-1, the column # 2 110 -2).

6 is a front view showing a first embodiment of an operating state of an anti-vibration damper provided on a structure.

Referring to Figure 6, the damper # 1 (400) for dustproofing is installed on the upper portion of the wall of the structure 100 (i.e., the upper beam 120-1, the column # 1 110-1, And the damper # 2 500 for dustproofing can be installed in the lower part of the wall of the structure 100 (i.e., the lower beam 120-2, the column # 1 110-1, the column # 2 110 -2). If a seismic load is applied to the wall, the wall may be distorted by an earthquake load. In this case, the coupling member # 3 of each of the vibration damper # 1 400 and the vibration damper # 2 500 can rotate in accordance with the earthquake load, thereby flexibly coping with the earthquake load. For example, the member # 1-2 forming the coupling member # 3 of each of the vibration damper # 1 400 and the vibration damper # 2 500 can rotate left or right around a hole formed at the center .

The cushioning material contained in the coupling member # 3 of each of the vibration damper # 1 400 and the vibration damper # 2 500 can offset a seismic load (for example, a vertical load and a horizontal load) (For example, a cushioning material including a hollow space in the form of a polygonal column) contained in the coupling member # 3 of each of the normal damper # 1 400 and the damper damper # 2 500, A wall provided with the damper # 1 400 for dust proofing and the damper # 2 500 for dust proofing) can be restored. For example, since the member # 1-2 forming the coupling member # 3 of each of the vibration damper # 1 400 and the vibration damper # 2 500 has a semicircular shape, The shock absorbing material can easily cancel the earthquake load applied in the rotating direction. That is, since the cushioning material can easily cancel the seismic load applied in the rotational direction to the vertical direction or the horizontal direction, the coupling between the damper # 1 (400) and the damper # 2 (500) The seismic performance can be further improved when the member # 1-2 forming the member # 3 has a semicircular shape.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
