Description
Technical field
The utility model relates to the plumbous shearing three-dimensional vibration isolating device of a kind of level, is mainly used in the basic vibration isolation of buildings such as house and bridge, belongs to structures isolation effect control and vibration isolation field.
Background technology
The secondary vibration of surrounding buildings thing is brought out in the track traffic meeting, and this vibration can have influence on people's normal life.At present both at home and abroad the ambient vibration that track traffic is brought out is many starts with from vibration source, and to the research of building foundation isolation mounting seldom.Earthquake motion itself has the multidimensional characteristic, and present three-dimensional base isolation device is mainly the tandem compound device of lead rubber bearing and thick rubber laminated rubber bases or disk spring.Three-dimensional isolation device changes the dynamic characteristics of superstructure to building superstructure and foundation " isolation ", can greatly alleviate the dynamic action of earthquake to superstructure, thereby reach the damping effect of " defeating a force with a tenderness ".The lead rubber bearing shock insulation is a kind of comparatively ripe engineering level seismic isolation technology in the horizontal direction, and the shear strain by lead for retractable pencil provides damping force, dissipation horizontal direction seismic energy.Thick rubber laminated rubber bases of in the vertical direction or disk spring can only reduce the vertical rigidity of structure, and vertical damping is not provided, this vertical energy of earthquake that can not dissipate effectively, and can not suppress the amplification of resonance region.
The utility model content
The utility model provides a kind of level plumbous shearing three-dimensional vibration isolating device, and this device can not only provide vertical damping effectively, suppresses the resonance amplification, and can be applied among the isolation environment vibration in conjunction with the characteristics of track traffic vibration source.
To achieve these goals, the utility model has been taked following technical scheme.This device mainly includes lead rubber bearing, lower connecting plate 1, upper junction plate 11, guide 8, wherein, all be provided with envelope steel plate 2 on the upper and lower surface of lead rubber bearing, the envelope steel plate 2 of lead rubber bearing soffit is connected with lower connecting plate 1, and lower connecting plate 1 is provided with and is used for the bolt hole that links to each other with the basis; The envelope steel plate 2 of lead rubber bearing upper surface is connected with guide 8, be provided with upper junction plate 11 above the guide 8, the guide rod of guide 8 partly is arranged on the inside of the sleeve part of upper junction plate 11, upper junction plate 11 links to each other with the superstructure of building, it is characterized in that: soffit in the sleeve part, the external surface of guide rod part is provided with N pin dish spring 10, the upper end of N pin dish spring 10 is the annular platform, circumference along this annular platform extends N pin, N foot bottom has plane contact between a platform and the guide 8, at N pin and guide 8 contacted positions, on two parts, all have groove, the groove of two parts complements each other to form a cavity, is marked with lead 9 in this cavity.
Described N is 4 or 8.
N pin dish spring 10 is to be improved by disk spring.Change the upper end of disk spring into an annular platform, the lower end changes the N pin into and supports, and N pin is made the plane, and between the guide 8 enough contacts area are arranged.When vertical motion, vertical displacement passes to the annular platform of N pin dish spring by the sleeve part of upper junction plate 11, the slip that makes N pin of N pin dish spring 10 produce horizontal direction, this slip drives the distortion of lead horizontal shear, thereby provides vertical damping power for this whole isolation mounting.
Because the utility model is mainly used in the lighter relatively building of load, by selecting the thickness of disk spring, use single disk spring just can provide suitable vertical rigidity, can make whole device highly controlled like this, thus work that can safety and stability.This device is by regulating its vertical rigidity the change of N pin dish spring parameter, and by changing the groove area, thereby change the horizontal shear area of lead, vertical damping is regulated, to reach the purpose of effective separating vibration.Bring out the secondary vibration of building for track traffic, based on vertical motion.The utility model can effectively be controlled vertical motion and the seimic horizontal vibration that building is brought out in track traffic, can reduce the vibration that earthquake motion causes the vertical direction of building to a certain extent simultaneously.
The beneficial effects of the utility model: after the disk spring structure is done certain change, improved the horizontal movement of spring lower end, thereby can make the lead at N pin place produce bigger horizontal shear distortion, improved vertical vibration isolation ability, reduced the vertical dynamic response of structure; Lead shear damper in the utility model is positioned at dish spring and guide inside, both can save the space, the design, process and install also comparatively favourable;
Simple in structure, stable performance, practical of the present utility model, have wide range of applications, applicable to the secondary vibration of isolating building that track traffic is brought out, and any occasion that existing three-dimensional isolation device was suitable for reduces the dynamic response of structure to isolate earth shock.
