Description
Technical field
The utility model is a kind of level-vertical composite shock insulation device, has suitable horizontal rigidity, vertical rigidity and damping, and enough vertical bearing capacities are arranged, and can realize reducing building level and vertical earthquake response simultaneously, belongs to a kind of building earthquake isolating equipment.
Background technology
In order to alleviate the building earthquake disaster to greatest extent, people have proposed the notion of structure control.The most feasible up to now control device or system comprise base isolation, damping energy dissipating and three kinds of schemes of ACTIVE CONTROL, and wherein base isolation is most widely used general." seismic design provision in building code " of the new promulgation of China is also included with " base isolation technology ", its objective is the superiority of giving full play to this new technology.But, these control device or system just reduce or the level of isolation geological process to greatest extent at present, because the shock insulation layer can not provide vertical relative motion, thereby can not play the effect of isolating or reducing vertical earthquake.But earthquake motion itself has the multidimensional characteristic, is positioned at important building and infrastructure near highly seismic region and the earthquake centre for some, considers that simultaneously level-vertical composite foundation the shock insulation of reduction level and vertical earthquake response is very necessary and important.Therefore, more and more scholars begins the research of the vertical composite shock insulation system of the level of paying close attention to, but does not make substantial progress as yet.
Summary of the invention
In order to overcome the existing base isolation device deficiency of level of isolation and vertical geological process simultaneously, the utility model provides level-vertical composite shock insulation device, and this device not only can the level of isolation earthquake, also can reduce vertical earthquake response effectively.
The technical scheme that its technical problem that solves the utility model adopts is: adopt stack of Belloville springs combined system in parallel as vertical base isolation system, put a main disk spring group in the centre, uniform auxiliary disk spring group around it is preferably 6～9.Because the centre pilot tube is arranged in the disk spring group, limited the horizontal movement of this device, make it almost vertical displacement can only take place.Because behind the disk spring stand under load, on area supported and superposed surfaces, between video disc and fairlead, the frictional force that produces because of the relative slip in surface is arranged all, in dynamic process, be presented as damping.The Luo Jinhua of HUST etc. show that to the experimental study result of butterfly spring the damping value that disk spring provides is easy to surpass the damping value that the general damping material can provide.Therefore this vertical earthquake isolating equipment has smaller vertical rigidity, and proper vertical damping can be provided, and this characteristic just in time can play isolating affection preferably to vertical earthquake.
At last, lead core rubber support is connected with the junction plate between the vertical earthquake isolating device, form the composite shock insulation system by bolt.
Design principle of the present utility model is: in actual engineering construction, the basal layer of building will provide stable vertical support for superstructure, has suitable vertical rigidity again, could reduce the vertical geological process of building.Because the disk spring axial dimension is less, radial dimension is bigger, is platypelloid type, and supporting capacity is bigger, therefore adopts the various combination form of disk spring to design a kind of vertical earthquake isolating equipment.Consider that lead core rubber support has outstanding horizontal shock insulation ability, and disk spring has good vertical earthquake isolating ability, therefore, if the two is organically merged, reasonably be combined into the disk spring neoprene bearing, so this new mechanism just has level and vertical earthquake isolating ability simultaneously.Like this, center master's disk spring group and auxiliary disk spring group can parallel connection be born upper load jointly, and higher vertical bearing capacity is arranged, under the normal mode of occupation of building structure, all conventional loads that can the safety supports superstructure guarantee the normal use of building structure.And, make this device have stability preferably because main disk spring group centre around auxiliary disk spring group is uniform, can effectively reduce the height of isolator.In addition, this device has suitable vertical and horizontal rigidity and damping capacity, and rigidity and damping are easy to adjust, and processing and fabricating is easy, stable performance.
Therefore the beneficial effects of the utility model are: effectively while level of isolation and vertically geological process.
Description of drawings
Fig. 1 is the facade constructional drawing of level-vertical composite shock insulation device.
Fig. 2 is the planar configuration figure of composite shock insulation device.
Among the figure, 1. center master disk spring group is 2. assisted the disk spring group, 3. upper junction plate, 4. upper junction plate bolt hole, 5. main disk spring group guide cylinder, 6. auxiliary disk spring guide cylinder, 7. disk spring device lower connecting plate, 8. lead core rubber support upper junction plate, 9. bolt, 10. rubber layer, 11. steel plates, 12. lead core rubber support lower connecting plates, 13. lead for retractable pencil, 14. glands.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Present embodiment is divided into two large divisions up and down, top is the vertical earthquake isolating device, be formed in parallel by center master's disk spring group 1, eight auxiliary disk spring groups 2, center master disk spring group 1 centering position wherein, the center that the center of auxiliary disk spring group 2 is distributed on center master's disk spring group 1 is on the great circle in the center of circle.There is main disk spring group guide cylinder 5 master's disk spring group 1 inside, center, there is auxiliary disk spring guide cylinder 6 auxiliary disk spring group 2 inside, guide cylinder is welded together in bottom and disk spring device lower connecting plate 7, and is enough big to guarantee vertical earthquake isolating device rigidity in the horizontal direction.Gland 14 is all arranged at the disk spring top of center master's disk spring group 1 and auxiliary disk spring group 2, be under the vertical uniform load q disk spring group put forth effort the position, make it stressed evenly, and flexible free.The top of vertical earthquake isolating device is a upper junction plate 3, utilizes the bolt hole 4 on the upper junction plate to be connected with superstructure.
The bottom of disk spring vertical earthquake isolating equipment is a lead core rubber support shock isolator.Lead core rubber support is to be formed through sulfuration by multilayer steel plates 11 and rubber 10, and heart hole is pressed into lead for retractable pencil 13 therein then.The lead core rubber support manufacture craft is simple, and better economy has suitable horizontal rigidity and damping capacity simultaneously.By bolt 9 lead core rubber support upper junction plate 8 and disk spring device lower connecting plate 7 are linked together.Like this, disk spring vertical earthquake isolating equipment and lead-rubber shock isolating pedestal connect to form level-vertical composite shock insulation device, connect together with the basis by lead core rubber support lower connecting plate 12.
Composite shock insulation device shown in Fig. 1,2 is placed the lower end of top, building foundation and post, the shock insulation layer is set, fix with steel plate, bolt anchoring, it is more convenient to construct.Present embodiment is all right level, vertical separately use when using.Vertical earthquake isolating equipment is arranged on the intermediate layer of building, and lead core rubber support is arranged on the base isolation layer.Like this, the bearing capacity that vertical earthquake isolating equipment need design reduces, a main disk spring group or add a few auxiliary disk spring group and just can obtain suitable vertical rigidity and bearing capacity, the height of vertical earthquake isolating equipment can shorten, design more simply, also be more conducive to the monolithic stability of structure.
