Description
Technical field
Patent of the present invention belongs to civil engineering structure earthquake isolation technical field, particularly, the present invention relates to marmem rolling level-vertical multidimensional shock insulation support.
Background technology
As everyone knows, engineering structures easily occurs to destroy even to collapse under violent earthquake effect.In recent years, in world wide, violent earthquake frequently occurs, and creates far-reaching economic and social impacts to various countries.Huge, the far-reaching earthquake of these destructions indicates that the world enters Earthquake Activity Periods.Therefore, safer efficient, important topic that more economical reliable building structure vibration-isolating system becomes seismic resistance field is studied.
But the domestic and international research to seismic isolation technology mainly rests on the shock insulation of simple horizontal direction at present, also rare to the research realizing multidimensional horizontal seismic isolation and vertical earthquake isolating simultaneously.Can be found out by a large amount of seismographic record statisticses, vertical seismic action peak accelerator and horizontal earthquake acceleration ratio 1/2 ~ 2/3, and the seismographic record having obtained that vertical component of acceleration meets or exceeds horizontal acceleration component.And a large amount of earthquakes shows, Vertical Earthquake Loads even exceedes horizontal earthquake action sometimes, and it can not be ignored the impact of structure.
Now, normal stack neoprene bearing is the seismic isolation technology of comparative maturity, due to the advantage such as its isolation property is remarkable, is widely applied in recent years.But along with going deep into of research and increasing of practice, normal stack neoprene bearing exposes some shortcomings.At present, the modulus of deformation of normal stack neoprene bearing is lower, and horizontal distortion is large and the distortion of large deformation rear support is difficult to reset; Damping is less, energy dissipation capacity is poor, and especially the relative deformation of superstructure and Seismic Isolation of Isolation Layer is larger; Normal stack neoprene bearing does not possess the ability of vertical earthquake isolating; Also there is the easily problem such as aging, perishable in normal stack neoprene bearing.Marmem, as a kind of brand-new functional material, has unique shape memory effect, superelastic effect, excellent damping capacity, anti-fatigue performance and decay resistance, is suitable for the exploitation of novel shock insulation, damping device.

Publication number is that the Chinese invention patent application of CN103899705A discloses a kind of compound shape memory alloy damper, comprise junction steel plate, lower junction steel plate, core dissipative cell, upper steel column with holes, lower steel column with holes, core dissipative cell is fixed between upper junction plate and lower junction steel plate, upper junction steel plate is identical with the limit number of lower junction steel plate, steel column with holes is installed on each summit of upper junction steel plate, upper steel column with holes and lower steel column with holes are all between upper junction steel plate and lower junction steel plate, hole on adjacent two the upper steel columns lower with holes of steel column with holes between it pass through on steel column with holes and lower steel column with holes is through shape-memory alloy wire bundle, shape-memory alloy wire bundle is fixed by fixture and upper steel column with holes.But this damper is only applicable to the power consumption of single direction, be difficult to carry out level, vertical multiple dimension shock-proof, meanwhile, damper adopts shape-memory alloy wire, easily damages under severe earthquake action.
Publication number is that the Chinese utility model patent of CN203256901U application discloses that a kind of shape memory alloy damping energy dissipating support, this utility model is by rubber element, upper strata junction steel plate, lower floor's junction steel plate, shape-memory alloy wire bundle, smooth torus and pulley composition, rubber element is connected with upper strata junction steel plate and lower floor's junction steel plate, lower floor's junction steel plate is connected with fixed reference system, upper strata junction steel plate is connected with carrier, smooth torus is uniformly distributed and is welded on upper strata junction steel plate and lower floor's junction steel plate, pulley sleeve is in smooth torus, shape-memory alloy wire bundle, pulley is arranged in bearing surrounding by smooth torus.But this bearing provides the scarce capacity of large power output, large output displacement at severe earthquake action undersetting, and level, vertical multiple dimension shock-proof cannot be realized.
Publication number is that the Chinese invention patent application of CN102839750A discloses a kind of mild steel-rolling shock insulation support, holder top is covering plate structure, top junction plate is connected with upper base plate, and upper base plate is connected with the column part of rolling plate, is connected to form overall composition covering plate structure.Rolling plate is supported on ball, ball be positioned over bottom seat groove in, seat groove provides scroll space for ball, make ball can in base part seat groove Free-rolling.Form through cavity between upper base plate and rolling plate, the upper board of resistance to plucking cover plate can insert when moving horizontally between this cavity, and resistance to plucking cover plate lower panel is fixedly connected with between seat groove.The cavity inside that seat slot is formed in resistance to plucking cover plate bottom.A mild steel bar is placed respectively at the corner place of top junction plate and resistance to plucking cover plate.Due to the mild steel that this bearing adopts, be difficult to after distortion reset.In addition, this bearing does not possess the ability of level-vertical earthquake isolating.
Summary of the invention
In order to overcome above problems of the prior art, the invention provides a kind of marmem rolling level-vertical multidimensional shock insulation support, and the feature of this bearing is that damping capacity is strong, dependable performance, can Self-resetting.
To achieve these goals, this invention takes following technical scheme.
The invention provides marmem rolling level-vertical multidimensional shock insulation support, this bearing comprises top cover plate, flat shape memory alloy bar, vertically shape memory alloy bar, bottom cover plate, base plate; This bearing comprises horizontal seismic isolation subsystem and vertical earthquake isolating subsystem, and horizontal seismic isolation subsystem is made up of bottom cover plate, base plate, ball and vertical shape memory alloy bar, and vertical earthquake isolating subsystem comprises top cover plate, side direction plate and flat shape memory alloy bar;
Described top cover plate comprises top board and central tube, and described bottom cover plate comprises cover plate and side direction plate;
Be fixedly connected with connecting bolt on the upside of described top board, be fixedly connected with described central tube on the downside of described top board; Each side surface of described central tube is fixedly connected with described flat shape memory alloy bar (ShapeMemoryAlloy, SMA, hereinafter referred to as SMA rod), each described horizontal SMA rod other end is fixedly connected with described side direction plate, described side direction plate is fixed on described cover plate, bottom described cover plate, surrounding is equidistantly fixedly connected with described vertical SMA rod, namely (and) each described SMA rod is equal with the distance between adjacent two SMA rods, the described vertical SMA rod other end is fixedly connected with described base plate, is fixedly connected with bottom described base plate with connecting bolt.
