Abstract
The utility model discloses a disk vertical shock insulation and power wasting damper, which comprises an upper supporting plate, a lower supporting plate, a shape memory alloy bar and a supporting rod arranged between the upper supporting plate and the lower supporting plate. The upper supporting plate is arranged with an upper sleeve, the lower supporting plate is arranged with a lower sleeve, the upper sleeve is sleeved on the lower sleeve, a plurality of vertical shape memory alloy bars are arranged between the upper sleeve and the lower sleeve, a spring is suited on the supporting rod, and a separating plate is arranged on the lower sleeve. The structure is adopted, so the vertical earthquake energy of the structure received from an earthquake is wasted with the prestrain processing performed to the shape memory alloy bar from the structure self weight and the stress strain reciprocation and delaying circulation of compressing-loosening performed in the foundation, according to the advantage that the shape memory alloy can produce phase changing pseudo elasticity under pressure.
Description
Technical field
The utility model relates to a kind of vibrating controller of civil structure engineering, particularly a kind of dish formula vertical earthquake isolating energy-consumption damper.
Background technology
In civil structure vibration isolation field, the research and development of passive vibrating controller have obtained large development, and existing earthquake isolating equipment mainly contains sand cushion, graphite mortar (adding the rod iron energy dissipating) shock insulation layer, friction slip or slide plate shock insulation layer, mortar (adding the reinforcing bar drawknot) shock insulation layer, PVC shock insulation layer, spin (or roller bearing) shock insulation layer, swing type foundation pile shock insulation way, elastomeric isolation pad with intermediate layers etc.At present, the technology comparative maturity and at home and abroad the earthquake isolating equipment of wide popularization and application be the standard elastomeric isolation pad with intermediate layers of sandwich clad steel and rubber layer tight bond.But these isolators are all only to horizontal shear force generation effect, and the vertical force that vertical motion is produced or not the power consumption effect.Under geological process, structure also can produce vertical motion except that producing horizontal vibration.For general isolator, only horizontal component is consumed energy, do not consider the influence of vertical motion, but vertical component exists still to the harm of structure.
Summary of the invention
The purpose of this utility model will provide a kind of dish formula vertical earthquake isolating energy-consumption damper exactly, and it can overcome the deficiency of existing isolator, reaches the purpose of implementation structure vertical motion control.
The purpose of this utility model is achieved in that a kind of dish formula vertical earthquake isolating energy-consumption damper, comprise upper supporting plate 1, lower carrier plate 2, marmem rod 6 and the pole 3 between upper supporting plate 1 and lower carrier plate 2, upper supporting plate 1 is provided with upper bush 4, lower carrier plate 2 is provided with lower sleeve 5, upper bush 4 is enclosed within on the lower sleeve 5, between upper bush 4 and lower sleeve 5, be provided with vertical marmem rod 6 one by one, be with spring 7 on the pole 3.Lower sleeve 5 is provided with space bar 8.Upper and lower sleeve the 4, the 5th, circular and circular interior section polygon, or circular circumscribed polygon.Upper and lower sleeve 4,5 also can be oval and oval interior section polygon, or oval circumscribed polygon.
Operating principle of the present utility model is: dish formula vertical earthquake isolating energy-consumption damper is under by the deadweight effect of control structure, the marmem rod produces certain prestrain, do the time spent at vertical motion, the marmem rod is continued compression or stress relaxation occurred on existing prestrain basis, bring out marmem rod inside thus and martensite phase transformation and reverse transformation constantly occur, produce the ess-strain hysteretic energy and be operated in the middle Fengman District of hysteretic loop, thus the vertical motion Passive Control of implementation structure.
The utility model is owing to adopt between upper and lower support plate, the structure of marmem rod is set in the upper and lower sleeve, so the utilization marmem can produce the martensite phase transformation under action of compressive stress, the attribute of phase transformation pseudoelasticity hysteresis effect occurs, reach the purpose that dissipation external force is passed to its energy; Again because employing is provided with the structure of space bar on lower sleeve, so can reach the effect of lateral-supporting and solid shape memorial alloy rod.The utility model also has advantage such as flexibly simple in structure, easy to use.
Description of drawings
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be among Fig. 1 A-A to sectional view.
Wherein, Fig. 1 double as Figure of abstract.
Among the figure: 1, upper supporting plate, 2, lower carrier plate, 3, pole, 4, upper bush, 5, lower sleeve, 6, the marmem rod, 7, spring, 8, space bar.
The specific embodiment
As shown in Figure 1, a kind of dish formula vertical earthquake isolating energy-consumption damper, comprise upper supporting plate 1, lower carrier plate 2, marmem rod 6 and the pole 3 between upper supporting plate 1 and lower carrier plate 2, upper supporting plate 1 is provided with upper bush 4, lower carrier plate 2 is provided with lower sleeve 5, upper bush 4 is enclosed within on the lower sleeve 5, is provided with vertical marmem rod 6 one by one between upper bush 4 and lower sleeve 5, is with spring 7 on the pole 3.Lower sleeve 5 is provided with space bar 8.Upper and lower sleeve the 4, the 5th, circular and circular interior section polygon, or circular circumscribed polygon.Upper and lower sleeve 4,5 also can be oval and oval interior section polygon, or oval circumscribed polygon.
During construction, dish formula vertical earthquake isolating energy-consumption damper is positioned between controlled works and its supporting mass, because the weight of controlled works itself, act on the upper supporting plate 1, institute is so that upper supporting plate 1 pressurized, cause marmem rod 6 stressed, produce certain prestrain, the spring 7 on the pole 3 also is subjected to force compresses simultaneously.When earthquake takes place, under the effect of earthquake vertical motion power, make lower carrier plate 2 stressed, marmem rod 6 is continued compression or loose on existing prestrain basis, bring out marmem rod 6 inside thus and martensite phase transformation and reverse transformation constantly occur, produces the ess-strain hysteretic energy, and be operated in the middle Fengman District of hysteretic loop, so repeatedly, reach the vertical motion Passive Control of implementation structure, reduce the harm of earthquake the civil structure thing.
