And formed, each single celled seamed edge length a is 2～5mm, and cell wall thickness t is 0.06～0.2mm.
Aluminum honeycomb/the number of lead complex, thickness and width and single celled rib length and wall thickness are according to energy consumer performance
Needs determine, energy consumer energy dissipation capacity requires higher, then can suitably increase aluminum honeycomb/lead complex
Number, thickness and width, simultaneously also suitably to increase comb core single celled seamed edge length and wall thickness,
So that comb core holds onto each unicellular interior lead block well.
During use, the composite energy dissipation device of the present invention is arranged on main equipment or building structure can produce relatively
On the position of deformation, when it runs into earthquake or high wind, upper and lower fixing plate produces relative displacement, and will outward
Power passes to the aluminum honeycomb/lead complex being constrained between upper and lower groove, and the lead in complex is owing to shearing
Extruding with aluminum honeycomb is consumed energy.Aluminum honeycomb cell wall can be consumed portion of energy, aluminum by shear force simultaneously
Honeycomb cell wall and lead joint contacting surface area are relatively big, and friction between the two also can consume certain energy so that whole
Individual energy consumer energy dissipation capacity improves.
The present invention compared with prior art has the advantage that
(1) simple and reasonable for structure, each little lead block be constrained on aluminum honeycomb unicellular in and give full play to power consumption
Performance, compound energy dissipation capacity is strong；
(2) polymer of fixing complex is cheap, anticorrosion, and has that adhesive force is strong, normal-temperature operation, executes
