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
The present invention relates to the damper field, be specifically related to a kind of metal sand damper, be used for the vibration isolation of civil engineering structure under strong wind, geological process.
Background technology
Research in recent years shows: civil engineering can be through being provided with the vibration that the effective inhibition of damper is caused by strong wind, earthquake etc. in structure.Though it is existing on the domestic market at present: various dampers such as metal yield damper, frcition damper, viscous liquid damper, tuned mass damper; But the application study in this field also is in the starting stage at civil engineering field; Therefore, the damper that also need develop various suitable different structures, demands of different is to satisfy the demand of engineering.Simultaneously, using the field of damper vibration damping also more and more in recent years, therefore develop practical and effective energy-eliminating shock-absorbing device more, is necessary.
Summary of the invention
The purpose of this invention is to provide a kind of metal sand damper, this damper stable performance, safety and environmental protection, simple structure, and cheap, construction maintenance is convenient, has big energy dissipation capacity.
A kind of metal sand damper comprises three block plates that stack, and is bonded with sheet rubber between adjacent steel plate; Offer a through hole in three block plates; Pour into metal sand in the through hole, the two ends of through hole are equipped with cover plate, and backing plate is equipped with in the cover plate inboard; Be provided with butterfly spring between backing plate and cover plate, three block plates place between the two clamping plates together.
Further, adjacent steel plate has interleave the steel dividing plate.
Further, said sheet rubber is bonded between the adjacent steel plate through sulfuration.
Technique effect of the present invention is embodied in:
Iron sand damper of the present invention is mainly through applying triaxial pressure to metal sand, makes it produce damping force with the shearing of rubber during amoeboid movement, thereby consumes the vibrational energy in the structure.When damper is in the shear strain state, owing to irritate the hole smaller volume of metal sand, metal sand nature three dimension stress.When damper mediates no deformation position, its circumferential pressure then by clamping plate through tighting a bolt, force the rubber vertical deformation, change the diameter of hole and produce; The vertical pressure of metal sand is then produced through forcing the disk spring distortion by cover plate.The effect of first steel plate 1 and second steel plate 2: 1. retrain sheet rubber; 2. the displacement with structure passes to damper.The effect of sheet rubber 3: 1. retrain metal sand; 2. make the opposing horizontal motion can take place between first steel plate and second steel plate; 3. the back in the wrong rigidity of damper is provided.The effect of metal sand 6: with the shear strain campaign of rubber the time by the friction generates damping force between metal sand.The effect of backing plate 7, disk spring 8, cover plate 9, bolt 10: apply precompression for metal sand.The effect of clamping plate 5 and bolt 11: apply precompression to rubber.The effect of steel dividing plate 4: the height of 1. regulating iron sand; 2. the vertical deformation of stabilising rubber sheet.Because rubber is isolated with air except that periphery one circle under the pressing of steel plate, and aging corrosion can not take place.Therefore, this metal sand damper has long service life, the damping force that provides is big and advantages such as reliable, simple structure, easy to make, low price.
