Definitions

  • the present invention relates to a steel material slit damper, and more particularly, to a steel material multi-slit damper having an improved seismic and damping performance capable of efficiently absorbing external vibrations affecting a building.
  • a steel plate constituting a slit damper is divided so that a short plate having a long length and a long plate having a long length are divided into upper and lower pairs, and these are arranged in tandem to adjust the yield displacement, and these slit dampers are disposed facing each other
  • the slit damper which acts on the large earthquake share the role of each other, thereby inducing the sequential yielding of the earthquake load according to the earthquake strength, thereby operating both the small earthquake and the large earthquake, thereby maximizing the seismic reinforcement effect.
  • the present invention is configured such that when the multi-slit damper is arranged in a left-right facing relation with a vertically divided structure, that is, left and right outer slit dampers (left panel and right panel) and inner slit damper
  • the inner slit damper (center panel) is designed to have a relatively low yield strength and the outer slit damper (left panel and right panel) is designed to have a relatively higher yield strength than the inner slit damper (center panel).
  • three slit dampers are arranged so as to be spaced apart from each other by a vertically divided structure.
  • the slit damping sections (slit holes) of the outer slit damper (left panel and right panel) are formed at the same height,
  • the outer slit damper (the left panel and the right panel) behaves simultaneously when an external force such as an earthquake is applied to the slit damping section (of the slit hole) at a different height, so that the yield strength Is relatively large.
  • the present invention is characterized in that the upper plate and the lower plate, which are upper and lower pairs in each slit damper, are spaced apart from each other in a groove-projection manner. Accordingly, when a large seismic force is applied, the upper plate and the lower plate are engaged with each other and the displacement is restrained, so that it is possible to withstand additional seismic loads in the case where the slit damping section (slit hole) is not broken.
  • the spacing space between the center top plate and the center bottom plate, the spacing space between the left top plate and the left bottom plate, and the spacing space between the right top plate and the right bottom plate are located at different heights,
  • the steel damper is deformed sequentially without being deformed at the same time so that the vibration can be smoothly absorbed, thereby minimizing the influence of the vibration applied to the building.
  • FIG. 3 is an exploded perspective view of a steel multi-slit damper with improved seismic and vibration damping performance according to an embodiment of the present invention.
  • FIGS. 4 and 5 are sectional views of a steel multi-slit damper with improved seismic and vibration damping performance according to an embodiment of the present invention.
  • FIG. 6 is a perspective view of a steel multi-slit damper with improved seismic and vibration damping performance according to another embodiment of the present invention.
  • the present invention relates to an elevator, comprising an upper support connected to the upper side of a building, a lower support connected to the lower side of the building, a central upper plate connected to the upper support and having a slit hole formed in the upper and lower direction, A left upper plate installed at the left side of the central upper plate and connected to the upper support, and a left upper plate disposed at a lower side of the left upper plate, A right upper plate installed at the right side of the center top plate and connected to the upper support plate, and a right upper plate disposed at the right side of the central upper plate, And the lower end is connected to the lower support and the slit hole is formed in the upper and lower direction, And the slit holes formed in the left panel and the right panel are positioned at the same height from each other and the slit holes formed in the center panel are positioned at different heights from the slit holes formed in the left panel and the right panel
  • the present invention provides a steel multi-slit damper with improved vibration damping performance.

  • the upper support 10 is connected to and fixed to the upper side of the building.
  • the center panel 30 is installed between the upper support 10 and the lower support 20 and includes a central upper plate 31 and a central lower plate 31 spaced apart from the central upper plate 31 by a predetermined distance, (32).

  • the fastening hole 31a is a hole through which the fastening bolt B passes as described above and is a hole used for firmly fixing the left panel 40 and the right panel 50 to the center panel 30.
  • the slit hole 31b is a slip damping section that minimizes the transmission of vibrations and the like to the building by distorting the shape of the steel damper according to the present invention while absorbing the external force when an external force such as an earthquake acts.
