Foamed aluminium is a kind of structure function material of excellence, has the advantages such as lightweight, high specific strength, high specific stiffness, damping capacity be good.Foamed aluminium/viscoelastic material composite material fills viscoelastic material, a kind of aluminium obtained and the intertexture composite material of viscoelastic material by being communicated with in foamed aluminium structure to three-dimensional open pores.This composite material, improves the mechanical properties such as the shearing of foamed aluminium, tension and compression, has the advantages that yield strength is low, plastic deformation ability is good, thus possess excellent hysteretic energy characteristic.Meanwhile, this composite material takes full advantage of the damper mechanism of foamed aluminium and viscoelastic material bi-material, possesses high damping characteristic.Therefore, this composite material has good hysteretic energy ability, can consider to use it for development of new power consumption wall device, is applied in structure energy-dissipating and shock-absorbing field, for building structure vibration damping controls to provide new tool.
Summary of the invention
Technical problem: the object of the invention is to the shearing lag return energy dissipation behavior utilizing foamed aluminium/viscoelastic material composite material excellent, proposes a kind of assembling foamed aluminium composite material damping power consumption wall device.
Technical scheme: a kind of assembling foamed aluminium composite material damping power consumption wall device of the present invention, comprises foamed aluminium composite material wallboard, fine aluminium section, junction plate, steel plate wall, split bolt; Fine aluminium section is respectively at the two ends up and down of foamed aluminium composite material wallboard, bolt hole is provided with for being connected with junction plate on the top of fine aluminium section, Long Circle hole is provided with for being connected with steel plate wall in the side of fine aluminium section, steel plate wall is arranged on both sides before and after foamed aluminium composite material wallboard, adopts split bolt that the steel plate wall of foamed aluminium composite material wallboard and its both sides is connected into power consumption wall device.
Foamed aluminium composite material wallboard is made up of foamed aluminium/viscoelastic material composite material, and foamed aluminium/viscoelastic material composite material adopts in hole viscoelastic material being packed into Open-cell Aluminum Foam and obtains.
Preferably, fine aluminium section 2 level is to being provided with bolt penetration hole.Bolt penetration hole is slotted hole, passes through and provide enough slipping space for split bolt.
Preferably, steel plate wall 4 has circular hole.
Beneficial effect: the assembling foamed aluminium composite material damping power consumption wall device related in the present invention, make use of the feature that foamed aluminium/viscoelastic material yield strength is low, plastic deformation ability is strong; Under little shake, middle shake, body of wall is unyielding, for structure provides lateral rigidity; Under large shake, body of wall enters surrender, is consumed energy by shearing lag return.Meanwhile, steel plate wall increases the out of plane stiffness of power consumption wall entirety, restrained effectively the outer unstable phenomenon of the contingent plane of power consumption wallboard.This power consumption wall device can replace common wall in building structure, neither takies the usage space of building, can realize again the effect of energy dissipation well; And this device is entirely assembling, installs, change conveniently.The proposition of this energy-dissipating device, has widened the range of application of foamed aluminium material, for it provides possibility in the application in building structure energy-dissipating and shock-absorbing field.
