Description
Technical field
The utility model relates to a kind of damper, particularly the plumbous composite damper of a kind of mild steel.
Background technology
Earthquake, as a kind of natural calamity, has the features such as sudden, unpredictability, does not also have the record of two secondary earthquakes to be the same in history, brings certain test to thus our the shockproof of building, bridge etc.The earthquake of China is divided into little shake, middle shake, large shake and megaseisms, and earthquake each time brings very large disaster to China area.In recent years, Chinese scholar have developed various new shock isolating pedestal, embody the features such as high damping, highly energy-consuming, multidimensional damping, technique is simple respectively, the steel lead combination core researched and developed as Wang Hao, Li Aiqun etc. subtracts shock insulation rubber bearing, there is the features such as damping is large, power consumption is stable, earthquake displacement is little, mild steel-the rolling shock insulation support of the research and development such as Xue Suduo, there is power transmission clearly stablize, be convenient to fabrication and installation, the advantage such as practical, the double-layer multi-dimensional shock absorption device of the research and development such as Xu Zhaodong, can to horizontal bidirectional and vertical damping simultaneously, and cheap.But, consider that common shock isolating pedestal exists certain drawback under macroseism, that is: under macroseism, excessive, the vertical compressive deformation of shock isolating pedestal sidesway reduces, easily cause vertical unstability, simple built-in lead for retractable pencil laminated steel plate neoprene bearing energy dissipation capacity is not enough simultaneously, also lack multistage energy-dissipating and shock-absorbing mechanism, the many performance objectives advocated at present can not be met and set up defences.Based on this, be necessary to research and develop and a kind ofly can guarantee reliably working under super expected earthquake and the novel earthquake isolating equipment of multistage energy-dissipating and shock-absorbing can be realized.
Utility model content
The problem that the utility model solves is the shockproof problem that the shockproof problem under all size vibrations occasion especially occurs when slightly vibrations.
For solving above-mentioned technical problem, the utility model provides the plumbous composite damper of a kind of mild steel, comprises upper junction plate, lead, mild steel central layer and base plate; The two ends of base plate are provided with lead, and the cross section of lead is dumbbell shaped, and the intermediate parallel of base plate is provided with some mild steel central layers, and the upper surface of mild steel central layer and lead is connected with upper plate jointly.
Further, the welding of mild steel central layer upper end is arranged on upper junction plate, and lower end welding is arranged on base plate.
Further, the upper surface welding of lead is arranged on upper junction plate, and lower surface welding is arranged on base plate.
Further, be arranged in parallel between upper junction plate and base plate.
Further, the spacing between two adjacent mild steel central layers is 15-20mm.
After adopting said structure, the damping to various vibrations can be met, especially when there are small size vibrations, damper also can deform, the distortion that hysteretic loop surrounds is approximately straight line, and vibrations disappear, and the distortion of damper also can disappear, ensure the abundant release of internal stress, improve the utilization ratio of damper.

Detailed description of the invention
Is the plumbous composite damper of a kind of mild steel as shown in Fig. 1 and Fig. 2, comprises upper junction plate 1, lead 2, mild steel central layer 3 and base plate 4; The two ends of base plate 4 are provided with lead 2, and the cross section of lead 2 is dumbbell shaped, and the intermediate parallel of base plate 4 is provided with some mild steel central layers 3, and the upper surface of mild steel central layer 3 and lead 2 is connected with upper plate 1 jointly.
Wherein the welding of mild steel central layer 3 upper end is arranged on upper junction plate 1, and lower end welding is arranged on base plate 4.The upper surface welding of lead 2 is arranged on upper junction plate 1, and lower surface welding is arranged on base plate 4.Be arranged in parallel between upper junction plate 1 and base plate 4.Spacing between two adjacent mild steel central layers 3 is 15-20mm.
The plumbous composite damper of mild steel is a kind of a kind of damper combining the elastic-plastic deformation power consumption of plumbous plastic deformation energy dissipation and mild steel.
The loading process of damper is divided into three phases: elastic stage, elastic-plastic phase, failure stage.Can produce the situation of thin tail sheep in time there is small size load, lead 2 enters yielding stage, now only has lead 2 stress deformation, mild steel central layer 3 is indeformable, do not there is provided rigidity, along with the increase of load, mild steel central layer 3 participates in distortion, start to provide rigidity, show be whole damper rigidity increase, the distortion that this time, hysteretic loop surrounded is less, still can think elastic stage, when load disappears after death, distortion also can disappear thereupon.When load do not disappear continue on the contrary increase time, the distortion that hysteretic loop surrounds is increasing, lead 2 is squeezed, the effect that distortion is sheared while increasing, the plastic property performance of lead 2 clearly, mild steel central layer 3 bears curved scissors effect, and elastic-plastic deformation occurs, and the distortion that the combination of lead 2 and mild steel central layer 3 can make hysteretic loop surround is round out gradually.After the whole surrender of damper, bearing capacity can continue to increase, and mainly because mild steel central layer 3 strength hardening, is now in elastic-plastic phase.When load continues to increase time, rupturing after mild steel central layer 3 and the commissure between upper junction plate 1 and base plate 4 can produce fatigue crack, is now failure stage.
The welding of mild steel central layer 3 upper end is arranged on upper junction plate 1, and lower end welding is arranged on base plate 4; The upper surface welding of lead 2 is arranged on upper junction plate 1, and lower surface welding is arranged on base plate 4, and lead 2 and mild steel central layer 3 are all adopt the mode of welding to be connected on upper junction plate 1 and base plate 4, being the intensity connected to increase it, ensureing its holding capacity.
Be arranged in parallel between upper junction plate 1 and base plate 4, damper can being made when bearing load, reaching the effect of mean forced.
Spacing between two adjacent mild steel central layers 3 is 15-20mm, and the preferential 15mm of this practicality, because now damping is best, ultimate bearing capacity is the highest.
| Spacing mm | Surrender rigidity (KN/mm) | Ultimate load KN |

| 16 | 1548 | 6580 |
| 17 | 1435 | 6486 |
| 18 | 1420 | 6450 |
