Description
Technical field
The utility model relates to build, municipal administration, bridge, electric power, water conservancy, the fields such as mining industry, and in particular to be applied to frame,
Framed bent, frame support, steel construction, composite structure, strengthening reconstruction, space structure, pylon, bridge, plank road etc. structural system
Metal damper.
Background technique
In well known technical field, existing metal damper generallys use several of continuous spaced set " dog bone
Formula " monolithic mild steel steel plate, by the out-of plane bending of area of section Minimum Area, realization energy-absorbing energy-dissipating simultaneously generates damping action,
This metal damper monolithic mild steel steel plate is thicker, and operating mode is single, and long-time service fatigue rupture hidden danger is obvious, damping effect
It is lower.It is therefore desirable to propose the new technical solution of one kind to solve the problems, such as this.
Utility model content
The utility model proposes a kind of biplate sandwich metal damper, solve in the prior art monolithic mild steel steel plate compared with
Thickness, operating mode is single, and long-time service is also easy to produce fatigue rupture, and service life is shorter, the lower problem of damping effect.
To achieve the goals above, the technical solution of the utility model is achieved in that a kind of metal damper, including
Loading plate, " dog bone type " biplate mild steel steel plate, friction material interlayer, " dog bone type " the biplate mild steel steel plate and loading plate weld
It connects, the friction material interlayer is arranged between " dog bone type " the biplate mild steel steel plate.
Preferably, the loading plate includes upper loading plate and lower loading plate.
Preferably, the thickness of the biplate mild steel steel plate, shape, geometric dimension are identical.
Preferably, bar shaped long hole is arranged in " dog bone type " biplate mild steel steel plate on it.
Preferably, in the long hole site of bar shaped of biplate mild steel steel plate and friction material interlayer, high-strength bolt is set.
Preferably, the friction material interlayer is aluminium sheet, and thickness is taken as the 30% to 36% of monolithic mild steel steel plate thickness,
Its shape, geometric dimension are identical with biplate mild steel steel plate, are also provided with identical bar shaped long hole on it, with biplate mild steel steel
Plate contraposition coincide.
Technology is compared, the utility model have an advantage that the utility model proposes biplate sandwich metal damper,
Firstly, bearing the active force and deformation that loading plate transmits after combining by three blocks of plates, by layers of material out-of plane bending, inhale
It can consume energy and generate damping action.Secondly, can be to biplate mild steel steel plate, friction material interlayer aluminium sheet by tightening the high-strength bolt
Apply compressive pre-stress, and then generate significant frictional force between layers of material, prevent the relative movement between plate, realizes and inhale
It can consume energy and generate damping action.Again, reaction force caused by two pieces of mild steel steel plain outside sweeps is equivalent in pairs is presented；
It is formed and prevents the counter-force of the relative movement between plate even, consumed energy and generate damping action.Above-mentioned latter two damping action is existing
Have in technology and be not present, therefore, the utility model compared with prior art, significantly improves the property such as energy-absorbing energy-dissipating and damping action
Energy.Simultaneously avoid in the prior art monolithic mild steel steel plate it is thicker, operating mode is single, be used for a long time fatiguability destroy, use the longevity
Order shorter problem.The utility model has more reliable energy consumption and damping capacity；Can more effectively resist earthquake, high wind,
The effects of shock, and can prolong the service life.
Detailed description of the invention
It, below will be to required in embodiment or technical description in order to illustrate more clearly of the technical solution of the utility model
The attached drawing used is briefly described, it is clear that, the accompanying drawings in the following description is only the embodiments of the present invention, right
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
His attached drawing.
Fig. 1 be the utility model proposes biplate sandwich metal damper structural schematic diagram；
Fig. 2 is A-A sectional view in Fig. 1；
In figure, 1 is loading plate, and 2 be " dog bone type " biplate mild steel steel plate, and 3 be high-strength bolt, and 4 be friction material interlayer.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the utility model proposes a kind of biplate sandwich metal damper, including loading plate 1, "
Dog bone type " biplate mild steel steel plate 2, high-strength bolt 3, friction material interlayer 4.The biplate mild steel steel plate and upper and lower two pieces carryings
Reciprocal sliding deformation and internal force variation that loading plate transmits are born in plate welding.Biplate mild steel steel plate, thickness, shape, dimensioning
It is very little identical.Biplate mild steel steel plate 2 and upper and lower two pieces of loading plates 1 weld, and friction material feed collet is arranged among biplate mild steel steel plate 2
Layer aluminium sheet 4, thickness are taken as the 30% to 36% of monolithic mild steel steel plate thickness.Its shape, geometric dimension and biplate mild steel steel plate are complete
It is exactly the same.The active force and deformation that loading plate transmits are born after three pieces of plate combinations, passes through layers of material out-of plane bending, energy-absorbing
It consumes energy and generates damping action.
As depicted in figs. 1 and 2, the utility model proposes a kind of biplate sandwich metal damper, biplate mild steel steel plate,
Friction material interlayer aluminium sheet opens up identical bar shaped long hole in the position shown in the figure 1.Perforation installation high-strength bolt, is twisted
The tight high-strength bolt can apply compressive pre-stress to each laminate material, and then significant frictional force is generated between layers of material, prevent
Relative movement between plate, energy-absorbing energy-dissipating simultaneously generate damping action.Two blocks of mild steel steel plates will be produced due to out-of plane bending simultaneously
Raw reaction force, which is formed, prevents the counter-force of the relative movement between plate even, and thus counter-force occasionally forms secondary energy consumption and damping and makees
With.
