Description

Steel Plate Damper

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel material damper, and more particularly, to a steel material damper capable of effectively absorbing external vibration affecting a building by improving buffering force.

The damper used in the seismic retrofitting method of steel structure or concrete structure used in domestic and foreign countries includes a steel damper (metal damper) which dissipates energy by using a yielding mechanism of steel, a friction damper which uses a friction mechanism as an energy dissipating device (Friction Damper), and viscous damper (Viscous Damper) which dissipates input energy using viscous material showing speed dependence.

With the start of steel dampers, friction dampers, and viscous dampers, vibration dampers have gained widespread acceptance as a way to improve seismic performance of seismic and structural engineering systems for the past 20 years. This trend is increasing.

Therefore, although many types of dampers are proposed recently, there is a problem that the structure is too complicated or the vibration absorbing effect is not high.

Here, the inner cylinder and the outer cylinder have check holes formed on both sides thereof facing each other in the longitudinal direction, respectively.

In the steel damper of the present invention constructed as described above, when a vibration or an impact is transmitted from the outside, the slit of the slit steel pipe is collapsed by the projecting pin provided on the outer cylinder to relieve the impact, There is an advantage that it can be prevented.

4 is a partial cut-away view of a steel material damper according to the present invention, FIG. 5 is a plan view of the damper shown in FIG. 1, and FIG. 6 is a view showing a steel damper according to the present invention installed on a steel structure .

The steel damper according to the present invention is installed in a quadrangular steel structure F installed on a wall surface of a building, and more specifically, is arranged diagonally at four corners of the steel structure F. The steel damper includes a slit steel pipe 10, an inner cylinder 20 surrounding the slit steel pipe 10, an outer cylinder 30 surrounding the inner cylinder 20, A lower cap 40 installed at the lower end, and an upper cap 50 installed at the upper end of the slit steel pipe 10.

The slit steel pipe 10 has a tubular shape of a rectangular cross section whose upper and lower ends are open and whose interior is empty. That is, the slit steel pipe 10 is connected to two steel panels of four steel panels so as to face each other to have a flat cross-sectional shape, and a plurality of slits 11 are formed on each surface at regular intervals.

The slit 11 is formed to penetrate each side of the slit steel pipe 10, and is formed to be long in the horizontal direction. The slit 11 reverses the plastic deformation when an external force such as vibration or seismic energy acts to absorb the vibration or seismic energy, thereby minimizing the influence on the building.

A through hole 12 is formed in each of the lower surfaces of the slit steel pipe 10.

The inner cylinder 20 has an upper and a lower end and is hollow and has a rectangular tube shape. The inner cylinder 20 is installed so as to be in surface contact with the outer surface of the slit steel pipe 10. That is, the inner cylinder 20 is connected to the two steel panels of the four steel panels so as to face each other, so that the flat cross-section is quadrilateral. The inner cylinder 20 has the through- .

The through hole 21 formed in the inner cylinder 20 communicates with the through hole 12 formed in the slit steel pipe 10.

The length of the inner cylinder 20 in the vertical direction is shorter than the length of the slit steel pipe 10 in the vertical direction.

Further, a check hole 22 is formed in the inner cylinder 20. The check holes 22 are elongated in the longitudinal direction on opposite sides of the inner cylinder 20 facing each other. Therefore, the shape of the slit 11 of the slit steel pipe 10 inserted into the inner cylinder 20 through the check hole 22 of the inner cylinder 20 can be confirmed.

The outer cylinder 30 has a tubular shape with an upper end and a lower end open and a hollow interior with a rectangular cross-section, and the inner side surface is provided so as to be in surface contact with the outer side surface of the inner cylinder 20. That is, the outer cylinder 30 is connected to each of the two steel panels of the four steel panels so as to face each other, so that the flat cross section is quadrilateral. The outer cylinder 30 has projecting pins 31 .

The projecting pin 31 is connected to the inside of each surface of the outer cylinder 30 and the projecting pin 31 passes through the through hole 12 of the slit steel pipe 10 and the through hole 21). The projecting pin 31 provided in the outer cylinder 30 penetrates through the through hole 12 of the slit steel pipe 10 and the through hole 21 of the inner cylinder 20 so that the slit steel pipe 10, The outer cylinder 20 and the outer cylinder 30 are not separated from each other in the vertical direction.

The length of the outer cylinder 30 is shorter than the length of the inner cylinder 20 in the vertical direction. Therefore, the length of the slit steel pipe 10 in the vertical direction is the longest, followed by the inner cylinder 20, and the shortest is the outer cylinder 30.

A check hole (32) is formed in the outer cylinder (30). The check holes 32 are elongated in the longitudinal direction on opposite sides of the outer cylinder 30 facing each other. The check hole 32 formed in the outer cylinder 30 communicates with the check hole 22 formed in the inner cylinder 20 and is inserted into the slit steel pipe 10 through the check hole 32 of the outer cylinder 30. [ The shape of the slit 11 can be confirmed.

The lower cap (40) is fixed to the lower end of the outer cylinder (30). The lower cap 40 is provided with a lower connecting rod 41 on its bottom surface. The lower connecting rod 41 is connected to a quadrangular steel structure F installed on the wall surface of the building. The lower cap 40 is fixed to the lower end of the outer cylinder 30 by welding or the like but is not fixed to the lower end of the slit steel pipe 10 or the inner cylinder 20. [ The projecting pins 31 of the outer cylinder 30 penetrate through the through holes 12 and 21 of the slit steel pipe 10 and the inner cylinder 20 so that the outer cylinder 30 and the inner cylinder 20, (10) are connected and fixed to each other.

The upper cap (50) is fixed to the upper end of the slit steel pipe (10). The upper cap 50 is provided with an upper connecting rod 51 on the upper surface thereof. The upper connecting rod (51) is connected to a quadrangular steel structure (F) installed on the wall surface of the building, so that the influence of the building due to external force such as vibration or seismic energy can be minimized. The slit steel pipe 10 and the lower ends of the inner cylinder 20 and the outer cylinder 30 are adjacent to the upper surface of the lower cap 40 and the length of the slit steel pipe 10 is larger than the length of the inner cylinder 20 or the outer cylinder 30. [ The upper cap 50 is not in contact with the upper end of the inner cylinder 20 or the outer cylinder 30. [
