Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0013] Depend on Figure 1 ~ Figure 3 As shown, the damper in the embodiment includes: a first steel plate 1, a second steel plate 2, a rubber sheet 3, a steel partition 4, a splint 5, metal sand 6, a backing plate 7, a disc spring 8, a cover plate 9, Bolt 10, Bolt 11.

[0014] The second steel plate 2 is placed between two steel separators 4, and together they are placed between two first steel plates 1, and the adjacent steel plates are bonded together by vulcanization with rubber sheets 3 and adhesives. , to form a composite part 1; a hole is opened in the middle part of the composite part 1; a backing plate 7, a disc spring 8 and a cover plate 9 are installed in sequence at one end of the hole and initially fixed with bolts 10; the iron sand 6 is poured from the other end Install backing plate 7, disc spring 8, and cover plate 9 in seque...

Abstract

The invention discloses a metal sand damper which comprises three stacked steel plates, wherein a rubber sheet is adhered between the adjacent steel plates respectively; a through hole is formed in the three steel plates; metal sand is filled in the through hole; cover plates are arranged at two ends of the through hole; padding plates are arranged inside the cover plates; belleville springs are arranged between the padding plates and the cover plates; and the three steel plates are placed between two clamping plates together. The metal sand damper provided by the invention generates a damping force by applying a three-directional pressure to the metal sand when moving along with the shearing deformation of the rubber, so as to consume vibration energy in the structure. The metal sand damper has the advantages of long service life, large and reliable supplied damping force, simple structure, convenience in manufacturing, low cost and the like.

Description

technical field [0001] The invention relates to the field of dampers, in particular to a metal sand damper used for vibration control of civil engineering structures under the action of strong winds and earthquakes. Background technique [0002] Studies in recent years have shown that civil engineering can effectively suppress vibrations caused by strong winds, earthquakes, etc. by setting dampers in the structure. Although there are various dampers in the domestic market: metal yield dampers, friction dampers, viscous liquid dampers, tuned mass dampers, etc., the application research in this field is still in its infancy in the field of civil engineering. It is necessary to develop various dampers suitable for different structures and different requirements to meet the needs of the project. At the same time, in recent years, there are more and more fields using dampers for vibration reduction, so it is necessary to develop more practical and effective energy dissipation an...
