Length to early stage rigidity；
By the tension cable wire tensioning, the precompression equal to design dead load is provided for laminated rubber bearing.
In such scheme, described tension cable wire and precompressed cable wire can be steel wire rope, or prestressing force steel hinge line.
The operation principle of above-mentioned three-dimensional isolation device vertical earthquake isolating is as follows：When vertical dynamic loading relative along the axis of guide post
During effect, pressure is delivered to upper head plate via laminated rubber damping bearing, makes upper and lower two end plates first to the dish-shaped bullet of mobile compression
Spring group；When dynamic loading is acted on opposite to each other along the axis of guide post, pulling force is delivered to upper head plate via tension cable wire, upper and lower two pieces of ends
Plate is moved away from, and pulls two pieces of floating platen relative movements compression disk spring groups respectively by two groups of precompressed cable wires.Thus
It can be seen that, no matter relative axial dynamic loading is or acts on three-dimensional isolation device opposite to each other, can compress disk spring group so as to sends out
Give birth to elastic deformation and consume energy.
From above-mentioned operation principle, the hole of the through hole on the precompressed cable wire described in the course of work and the floating platen
Wall can not produce friction, otherwise interfere with moving up and down for floating platen, and therefore the through-hole diameter is than the precompressed cable wire
Diameter how many greatly, not disturb and moving up and down for floating platen should be affected to be advisable.
The three-dimensional isolation device that vertical early stage rigidity can be adjusted of the present invention, wherein described precompressed cable wire are fixed on
One on floating platen can adopt conventional method anchoring, and the U-shaped similar to lifting bolt or by bar bending may also be employed
Component system connects fixation.
The three-dimensional isolation device that vertical early stage rigidity can be adjusted of the present invention is had the effect that compared with prior art：
(1) in the vertical direction, you can compression energy-dissipating and shock-absorbing, and stretchable energy-dissipating and shock-absorbing；Effectively can build depletion high level
The huge pulling force that thing is produced to building foundation is built due to waving；And one group of disk spring is only needed, vertical extension is little, stability
Good.
(2) after vertical dynamic loading is more than the defensive ability/resistance ability of default vertical early stage rigidity, vertical earthquake isolating in the present invention
The bidirectional elastic deformation of seat is symmetrical, does not therefore affect the effect of its compression power consumption because of the change of the positive negative direction of vertical load
Really；
(3) if change two groups of precompressed cable wires length can change whole device vertical early stage rigidity, external force gram
Earthquake isolating equipment cannot be made before taking the vertical early stage rigidity to produce vertical deformation, building effectively be inhibited in small earthquake and weak
Produce in the presence of wind shake and rock, the shockproof grade of the wind resistance of predeterminable building significantly reduces the shockproof cost of wind resistance；
(4), during presetting early stage rigidity, effective active length of the disk spring group is constant, will not change dish-shaped bullet
The original characterisitic parameter of spring group.
(5) using cable wire self-locking tensioning anchorage anchor by the other end of precompressed cable wire, one be can be to the length of precompressed cable wire
It is adjusted, two is using the anti-synergy for turning round compression spring and the first self-centering locking fixture, can effectively prevent pre- compressed steel
Rope is twisted during length adjustment is carried out and changes the characterisitic parameter of cable wire.
(6) thing that can effectively buffer building rocks stretching and the compression shock that trend is produced to building basis, further
Reduce the risk that building topples.

Referring to Fig. 1～3, in order to realize the purpose of predeterminable vertical early stage rigidity, above-mentioned three-dimensional isolation device installation method
As follows：(1) first according to default vertical early stage rigidity and the characterisitic parameter of disk spring group 4, calculate disk spring group 4 and meet
Length during vertical early stage rigidity；(2) vertical earthquake isolating bearing is assembled by Fig. 1, makes the other end of each precompressed cable wire certainly
First taper jaw 18-7 of corresponding cable wire self-locking tensioning anchorage 18, the second taper jaw 18-9 and hollow bolt 18-10
Pass in centre bore；Then, (3) are connected on the fag end system of the precompressed cable wire for exposing on traction stretching machine, and in traction tensioning
Simultaneously monitor the distance between two pieces of floating platens；Disk spring group 4 is compressed when the distance between two pieces of floating platens are equal to
To meet vertical early stage rigidity length when, move forward the second self-centering locking fixture, at the same adjust turn tensioning swivel nut 18-
6 so that plane bearing 18-2 is clamped tightly between the tensioning swivel nut 18-6 and tapered sleeve 18-8, and anti-torsion compression spring 18-1
Compressed, the tension force produced by which promotes the first taper jaw 18-7 reaches to clamp precompressed cable wire, turns described sky thereafter
Heart bolt 18-10 will be dead positioned at precompressed cable wire folder in the second taper jaw 18-9；Finally, traction stretching machine is removed, and it is unnecessary to block
Precompressed cable wire, you can disk spring group 4 is clamped between two pieces of floating platens all the time.(4) hereafter load onto laminated rubber every
Shake bearing, obtains final product the three-dimensional isolation device.
When presetting vertical early stage rigidity, the tension force sum of two groups of precompressed cable wires need to be more than or equal to the three-dimensional isolation device institute
The erect static load lotus that bears.
Referring to Fig. 1 and Fig. 7～11, in the work progress for installing three-dimensional isolation device or in routine maintenance procedure, if
It was found that the tension force of certain precompressed cable wire is not enough, you can the tensioning swivel nut 18-6 turned in cable wire self-locking tensioning anchorage 18 is adjusted.
Under ideal conditions, the vertical ripple of earthquake should be unable to occur to building during building transmission by earthquake isolating equipment
Displacement.This is based on, the operation principle of this example three-dimensional isolation device vertical earthquake isolating is as follows：Referring to Fig. 1, when the vertical ripple of earthquake is produced
When raw dynamic loading overcomes the vertical early stage rigidity, if the dynamic loading pushes end plate 3 along the axis of guide post 1, on
The counteracting force of end plate 2 just compresses downwards disk spring group 4, and building is motionless with shifting on ground for bottom plate 3；If the dynamic load
Axis drop-down bottom plate 3 of the lotus along guide post 1, two groups of precompressed cable wires pull two pieces of floating platen relative movements compressions respectively
Disk spring group 4, and bottom plate 3 is then moved down with ground away from upper head plate 2, now building is still motionless.As can be seen here, local
When shake compressional wave makes ground generation up-down vibration, compressible disk spring group produces elastic deformation and consumes energy.In the same manner, building exists
When rocking in the presence of wind shake or flatly seismic wave, no matter to its to the dynamic loading that the three-dimensional isolation device is produced be pulling force also
It is that the compressible disk spring group of pressure produces elastic deformation and consumes energy.
