Description
Technical field
The present invention relates to a kind of vertical spacing-type lead shearing three-dimensional vibration isolation device, this device is combined by lead rubber bearing, disk spring, plumbous damping and vertical spacing device, has the vertical spacing function, be mainly used in the basic vibration isolation of buildings such as house and bridge, also can be applicable to the equipment vibration isolation.Belong to structures isolation effect control and vibration isolation field.
Background technology
Earthquake isolating equipment 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 research of building foundation isolation mounting is a lot, but mainly concentrates on horizontal vibration isolation direction, and the three-dimensional vibration isolating device that can effectively isolate vertical motion is few in number.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, vertical damping is not provided, the vertical energy of earthquake effectively can not dissipate, and can not suppress the amplification of resonance region, the vibration isolation lead damper that present disk spring is adopted mostly is built-in damping, and processing, installation, monitoring and maintenance are equal inconvenient.The disk spring device belongs to loosely connected system in addition, exists the situation of upwards bounce-back to take place, and controls the vibration isolation function failure that improper meeting causes system.
Summary of the invention
Can not effectively provide vertical damping, damper that the situation generation that the position is unreasonable and solution dish spring rebounds and causes the isolation mounting actual effect is set in order to overcome existing three-dimensional isolation device, the invention provides a kind of novel three-dimensional vibration isolating device, this three-dimensional vibration isolating device can not only provide vertical damping effectively, more can conveniently install, overhaul and safeguard, and can control vertical deflection, assurance device can operate as normal.
To achieve these goals, the present invention has taked following technical scheme.The present invention includes upper junction plate, lead rubber bearing, disk spring and the lower connecting plate of fixedlying connected with superstructure; Fixedlying connected with upper junction plate in the top of lead rubber bearing, fixedlys connected with substructure in the bottom.Disk spring is placed between upper junction plate and the lower connecting plate and carries out spacing by the interior guide peg of fixedlying connected with upper junction plate with the outer guide peg of fixedlying connected with lower connecting plate.Also include and be arranged on the outer guide peg covering steel plate outside, that fixedly connected with upper junction plate, the covering steel plate with outside the corresponding position of guide peg the two be provided with groove, in groove, be perfused with lead.
The both sides along continuous straight runs of guide peg is provided with the through hole through outer guide peg outside, and the diameter of through hole is greater than the diameter of spacing screw rod, and spacing screw rod is arranged in this through hole and its two ends are passed this through hole and fixedlyed connected with the covering steel plate.Spacing screw rod can move with the covering steel plate, and spacing screw rod can move up and down in the through hole of guide peg outside, up spacingly do not stress fully to the dish spring, descending spacingly flatten fully to the dish spring.
Groove on the described covering steel plate runs through the covering steel plate, the fixedly connected sealing lead steel plate that is useful on lead in the sealed groove in the outside of covering steel plate.
The present invention guide peg and last envelope steel plate inside outside is provided with lead shear damper.The vibration that three-dimensional vibration isolating device upper junction plate under the excitation of vertical load produces vertical direction, this vibration drives lead shear strain, thereby provides vertical damping power for three-dimensional vibration isolating device.Between guide peg and the covering steel plate vertical spacing device is set outside simultaneously, the guide peg both sides are provided with through hole outside, fixedly connected with the covering steel plate in the two ends of spacing screw rod, and move with the covering steel plate, spacing screw rod can move up and down in the through hole of guide peg outside, not up spacingly do not stress fully to disk spring, descending spacingly flatten fully to disk spring.Spacing screw rod can effectively be controlled the bounce-back of instantaneous dish spring, and this stopping means has the clamping plate effect simultaneously, and structure is applied level to precompression, prevents that the extruding after the plumbous surrender from losing.
The invention has the beneficial effects as follows: the lead damper among the present invention provides vertical damping, and its position makes things convenient for installation, maintenance and detection; The use of spacing screw rod has guaranteed the normal function of use of system under big displacement situation, out-of-control condition can not occur when disk spring rebounds.Simultaneously can avoid excessive lead loss, for the normal use of installing provides safeguard.
Simple in structure, stable performance, practical of the present invention, have wide range of applications, secondary vibration applicable to building that traffic is brought out, and any occasion that existing three-dimensional isolation device was suitable for is to isolate earth shock, reduce the dynamic response of structure, can be applied to simultaneously the vibratory equipment bottom, with the vibration effect of xegregating unit vibration to surrounding environment.
