Description
Technical field
The present invention relates to a kind of building vibration proof (or vibrations) device, be specifically related to three-dimensional isolation device.
Background technology
Three-dimensional isolation device is a kind of shockproof isolating device being located between building and basis, effectively can inhale from various dimensions
Receive, dissipate the outside energy inputted, thus reaches to protect the purpose of building safety.Three-dimensional isolation device is generally by vertical earthquake isolating
Bearing and horizontal seismic isolation bearing combine, and both absorb both vertically and horizontally seismic wave respectively.
It is known that the development of three-dimensional isolation device depends on the technological progress of antivibrator.At present, actual application is really entered
The antivibrator of main flow mainly have three major types, i.e. laminated rubber antivibrator, metal spring antivibrator (mainly disk spring and spiral shell
Rotation spring) and viscoelastic damper (bigger static load can not be undertaken).Therefore, on the existing three-dimensional shock isolation support overwhelming majority is all
State the combination of antivibrator, and be essentially all laminated rubber antivibrator and connect up and down with metal spring antivibrator.In order to overcome
Laminated rubber resistance to tension is weak, disk spring can not draw and helical spring initial stiffness is low different from compression property with stretching
Shortcoming, has some three-dimensional shock isolation supports to be additionally arranged tensile structure (as set up steel wire rope in surrounding) at laminated rubber antivibrator,
Also (or other Stretch material, such as rhombus steel by metal spring antivibrator and viscoelastic damper some three-dimensional shock isolation supports
Plate etc.) compound, utilize metal spring antivibrator to undertake static load and compression shock absorption, utilize viscoelastic damper stretching, compression power consumption.
But, the antivibrator that multiple flexible member is compound, not only structure is complicated, and needs when designing to consider horizontally and vertically to associate journey
Degree, calculates sufficiently complex.
A kind of three-dimemsional vibration insulationg system disclosed in the patent application of Publication No. CN1560395A, this system is common
Tandem compound disk spring and the viscoelastic damping being located in disk spring axis of guide centre bore on lead for retractable pencil laminated rubber vibrating isolating device
Device realizes.But, owing to viscoelastic material is relatively big with the damping characteristic difference of disk spring, and both correlation degrees have
Much, these are all intended to be determined by experiment；Especially, when described three-dimemsional vibration insulationg system is by when being pressed to tension transition,
Although disk spring is inoperative, but the energy stored by disk spring can be added on viscoelastic damper, makes viscoelasticity
Antivibrator obtains bigger initial acceleration, and viscoelastic damper is then a kind of velocity sensitization type antivibrator, it is clear that dish bullet
The impact of viscoelastic damper be can not be ignored by the energy stored by spring, and how this impact calculates, then be a difficulty
Thing.For another example a kind of three-dimensional isolation device disclosed in the patent application of Publication No. CN101761147A, this device is pressed to
During tension transition, wherein the energy of six disk spring storages also can be delivered on rhombic steel plate antivibrator by screw rod, equally
The problem that there is also design dyscalculia.Additionally, slide block, rail plate and the height in the scheme of CN101761147A patent application
Hale Horizontal limiting and stretch-proof organization that rope is constituted, not only make design dyscalculia, but also add whole shock isolation system
Complexity.
Summary of the invention
The technical problem to be solved is to provide a kind of pull bar guide type helical spring three-dimensional shock isolation support, and these are three years old
Dimension shock isolating pedestal, only with a kind of antivibrator, is not only simple in structure, and can antidumping.
The present invention solves the technical scheme of above-mentioned technical problem:
A kind of pull bar guide type helical spring three-dimensional shock isolation support, this bearing includes the upper junction plate being parallel to each other, lower company
Fishplate bar and be located between upper junction plate and lower connecting plate and be provided with four pull bar guide type coiled spring damper, each pull bar guides
Linked together by universal ball end respectively between connecting rod and upper junction plate and the lower connecting plate at formula coiled spring damper two,
Form the truncated rectangular pyramids structure that a two opposite side surfaces is respectively symmetrically；
Described pull bar guide type coiled spring damper includes helical spring, and two of this helical spring is from helical spring
End face be outwards sequentially provided with floating platen and dynamic pressure plate, each dynamic pressure plate one side opposing with floating platen is along described spiral bullet
Spring axis stretches out a connecting rod, and the end of this connecting rod is provided with bulb；
Being provided with two groups of precompressed pull bars parallel with the axis of helical spring respectively between described two floating platens, each group pre-
Pressure pull bar be three less, one of which is distributed in the centre bore of helical spring around the axisymmetrical of helical spring, another group around
The axisymmetrical of helical spring is distributed in the surrounding of helical spring；One of each group of precompressed pull bar is separately fixed at and is positioned at spiral
On the floating platen that spring is, other end be each passed through be positioned at helical spring other end floating platen and press with this floating
The dynamic pressure plate that plate is adjacent is fixed on a limit element；
Described limit element is respectively acting on the dynamic pressure plate being positioned at helical spring two, will by two groups of precompressed pull bars
Distance limit between two pieces of floating platens be helical spring be compressed to preset rigidity time length.
For ease of the distance between two pieces of floating platens of regulation so that it is equal to helical spring is compressed to preset the length of rigidity
Degree, the limit element described in such scheme is hexagonal flange nut, and described precompressed pull bar is polished rod bolt, and the two screw thread is even
Connect and be fixed on.
In order to avoid producing rigid impact between limit element and dynamic pressure plate and the second end plate, in such scheme, described
Elastic polymer material it is embedded with limit element, such as sheet rubber on the surface that dynamic pressure plate contacts.
In such scheme, the described angle between pull bar guide type coiled spring damper and lower connecting plate can be according to whole
Dead load and default earthquake intensity that individual bearing is undertaken select.
Antivibrator of the present invention has the advantages that
(1) the axial force either forward born due to each pull bar guide type coiled spring damper is the most anti-
To, helical spring all can produce elastic compression deformable shock-resistant, and three-dimensional shock isolation support the most of the present invention can seismic wave isolator
Horizontal direction component, vertical component and torsional component, and then realize three-dimensional isolation truly.
(2) whole bearing is mainly made up of the pull bar guide type coiled spring damper that two pieces of connecting plates and four are same,
Not only structure is simple and direct, and the transfer route of power is clear, clear and definite, greatly reduces design difficulty in computation.
(3) length changing precompressed pull bar can change the initial stiffness of each pull bar guide type coiled spring damper,
Therefore can calculate the initial stiffness of each antivibrator according to the static load that each bearing is to be undertaken, and then ensure withdrawing support
The vertical displacement of rear building is little, does not even produce vertical displacement.Visible three-dimensional shock isolation support of the present invention had both been suitable for new
The building shock insulation built, also is adapted for the shock-insulating reconstruction of existing building.
(4) not only can realize three-dimensional isolation truly, but also there is the effect of antidumping.
