Description
Technical field
The present invention relates to a kind of shock isolation system.
Background technology
The building foundation shock insulation is exactly that the flexible shock insulation layer that one deck has enough reliabilities is set between building and the basis, and the control seismic wave is to the superstructure transmission.Theory shows that with experimental study and engineering practice the base isolation technology is that a kind of building is resisted one of most effectual way of earthquake disaster.At present, the research of the shock insulation of horizontal earthquake component has obtained gratifying achievement in countries in the world, and has been widely used in the engineering practice.But because the ground motion during earthquake is spatial movement, except seismic wave flatly, vertical seismic wave has same destructiveness.To near the zone some highly seismic regions and the earthquake centre, vertical seismic components is very obvious, more than 2/3 of the seismic components that is up to the standard especially.Yet, the base isolation system that succeeds in developing both at home and abroad at present, (based on laminated rubber damping bearing) is the horizontal earthquake shock isolation system, but cuts little ice for vertical seismic wave.Up to now, the three-dimensional isolation systematic research of carrying out seismic wave flatly and vertical seismic wave simultaneously of domestic external enwergy does not still have substantial progress.Therefore, be badly in need of the three-dimensional isolation system of a kind of while level of isolation seismic wave of exploitation and vertical seismic wave, in order to improve structure greatly in the comprehensive ability of resisting earthquake disaster.
In addition, mechanical oscillation also have a strong impact on safety, equipment operator healthy of structure and upset resident's normal life.At present, though more vibration damping and vibration isolation device is arranged, nearly all be folk prescription to vibration isolator, and bearing capacity is less, lacks the three-dimensional vibrating vibration isolator of large bearing capacity.
Summary of the invention
The objective of the invention is to overcome above-mentioned prior art and can not isolate and suppress flatly seismic wave and the weak point of vertical seismic wave simultaneously to the upper building transmission, a kind of three-dimensional isolation system is provided, and this system can isolate and suppress flatly seismic wave and vertical seismic wave simultaneously to the upper building transmission.
For achieving the above object, the technical solution used in the present invention is: alternately pile up sheet rubber on lower connecting plate, steel disc and sheet rubber, on its topping rubber sheet, be equipped with middle junction plate, fixed guide on middle junction plate, protruding axle is housed in guide, be equipped with damping material between protruding axle and the guide, cover plate is housed on damping material, cover plate and guide fix, stretch out outside the guide upper end of protruding axle, movingly, and leave the gap between lower surface and the guide between its lower end and the guide, on the disk spring composite part, be equipped with upper junction plate, upper junction plate and protruding axle fix, and between the lateral surface of guide movingly, and and leave the gap between the upper surface of guide, the involutory number of disk spring composite part is at least two, be enclosed within on the guide lateral surface, and between the guide movingly.
Can substitute above-mentioned steel disc with cloth.
Between above-mentioned two disk springs, can be equipped with film.
The invention has the advantages that:
1. this system has suitable rigidity of three-dimensional and damping capacity simultaneously, the bearing capacity of single bearing big (can reach the hundreds of ton), and bearing capacity, rigidity and damping are adjusted especially easily.
2. this system construction is simple, long service life, and stable performance, material therefor is drawn materials extensively, and processing and manufacturing is easy, and is therefore with low cost.
3. this system has multipurpose, has great direct economic benefit and social benefit.
This system both can be used for the three-dimensional base isolation of engineering structures, can firmly support superstructure and prevent to build the rotation of toppling effectively, alleviate seismic energy and pass on, the loss that effectively alleviates even avoid earthquake that engineering structures and people's property are brought to superstructure; The vibration that can also be used for plant equipment is simultaneously isolated, and alleviates the harm of mechanical oscillation to structure, environment, personnel.

Fig. 1 is the structure diagram of an embodiment of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the structure diagram of the another kind of embodiment of the present invention.
The specific embodiment
In the present invention, the involutory number of disk spring 8 composite parts generally can be the even number between 2～16.Disk spring 8 composite parts can contain 1～6 disk spring 8, and contain 2～4 disk springs 8 for best, can be equipped with film 7 between two disk springs 8.
By illustrated in figures 1 and 2, the present invention includes steel disc 1, sheet rubber 2, lower connecting plate 3, preventing rubber layer 4, middle junction plate 5, damping material 6, film 7, disk spring 8, guide 9, steel overcoat 10, upper junction plate 11, protruding axle 12, damping material 13, cover plate 14.
Gap between the lower surface of above-mentioned protruding axle 12 and the guide 9 can and upper junction plate 11 equate with gap between guide 9 upper surfaces, and more than or equal between disk spring 8 composite parts apart from sum 2h.
Lower connecting plate 3, the sheet rubber 2 that alternately piles up on the lower connecting plate 3, steel disc 1 and sheet rubber 2, middle junction plate 5, damping material 6 constitutes horizontal shock isolating pedestal, it has gentle horizontal rigidity and higher damping, vertical rigidity is very big, and main occurred level shear strain is used for the level of isolation seismic wave during earthquake.Four disk spring that is involutory 8 composite parts, film 7, guide 9, upper junction plate 11, protruding axle 12, damping material 13 and cover plates 14 constitute the vertical earthquake isolating bearing, it has suitable vertical rigidity and damping capacity, horizontal rigidity is very big, vertical displacement almost only takes place during earthquake, is used to isolate vertical seismic wave.
When earthquake takes place when, to produce bigger horizontal movement and vertical displacement between upper junction plate 11 and the lower connecting plate 3 in the three-dimensional isolation system, the natural vibration period that makes structure level vibration and vertical motion is away from the place predominant period, thereby makes structural vibration away from formant.In addition, damping material 6 and 13 also reduces structural vibration with the absorption portion seismic energy.Like this, because most of seismic energy is absorbed by the three-dimensional isolation system consumption, the fraction seismic energy passes to superstructure, thereby makes structure produce less vibration, reaches the purpose of shock insulation.
By shown in Figure 3, different with Fig. 1 is: disk spring 8 composite parts are made of two disk springs 8 and the film 7 that is clipped in therebetween, and such composite part has six and is involutory.To the centre bore of middle junction plate 5, damping material 6 is not set at lower connecting plate 3, the lower surface of protruding axle 12 and the gap between the guide 9 can more than or equal between disk spring 8 composite parts apart from sum 3h.
Usable fibers cloth substitutes steel disc 1, and cloth is carbon cloth or aramid fiber cloth etc., and the employing cloth has increased the damping of horizontal shock isolating pedestal, and processing is easier, and cost is lower.
