The specific embodiment
Below in conjunction with accompanying drawing the utility model patent is further specified.
Present embodiment is a kind of simple-pendulum compound three-dimensional shock isolation support, by base 5, and compositions such as guide cylinder 2, guide peg 1.
See Fig. 1-3, base 5 is positioned at the bottom of bearing, is metal construction, and the bottom surface of base 5 is the plane, is positioned on the level basis 6, and the top of base 5 is sphere slideway 9, is provided with spherical slide block 11 in the sphere slideway 9.Spherical slide block 11 slides on sphere slideway 9.Between spherical slide block 11 and sphere slideway 9, be provided with polytetrafluoroethylene (PTFE) backing plate 12.Polytetrafluoroethylene (PTFE) backing plate 12 is embedded in the bottom surface of spherical slide block 11, is spherical surface construction, and its spherical radius is identical with the spherical radius of sphere slideway 9, contacts fully to guarantee both.The spherical radius of sphere slideway 9 can design according to load, utilizes the horizontal vibration cycle of the design cycle extending structure of slide plane, reduces the horizontal vibration effect of superstructure 13 effectively; Simultaneously, the polytetrafluoroethylene (PTFE) backing plate 12 that between spherical slide block 11 and sphere slideway 9, is provided with, utilize its follow spherical slide block 11 when moving and the friction between the sphere slideway 9 come the consumption level seismic energy, reduce geological process.The top of spherical slide block 11 is bolsters 10, and bolster 10 is divided into collet and guide peg 1 two parts.Collet is fixed on the spherical slide block 11, and guide peg 1 is installed in forms bolster 10 on the collet, and the periphery of bolster 10 is provided with guide cylinder 2.Guide cylinder 2 is divided into chamber and following chamber two parts, goes up indoor filling visco-elastic damping material 7, and these visco-elastic damping materials 7 utilize the capping on guide cylinder 2 tops to be sealed in the guide cylinder 2.Between following chamber interior bolster guide peg 1 and guide cylinder 2, disk spring 8 is set on the collet.By being arranged at the disk spring 8 between guide peg 1 and the guide cylinder 2, in the extending structure vertical motion cycle, reduce the effect of superstructure 13 vertical motions reaction.The rigidity of disk spring 8 can design according to the shock insulation needs, thereby is applicable to different upper load conditions; Utilize the rubbing action between the spring video disc of disk spring 8 and the visco-elastic damping material 7 of last indoor filling, can consume vertical seismic energy, reduce superstructure 13 earthquake responses; By the cooperation of guide peg 1 and guide cylinder 2, the direction of vibration of control superstructure 13 prevents superstructure 13 and bearing unstable failure.In the outside of guide cylinder 2, around guide cylinder 2, support 3 is set, support 3 tops are top board 4, in order to support superstructure 13.
Operating principle of the present utility model:
Under the effect of seismic wave flatly, superstructure of the present utility model slides in the sphere slideway 9 of base 5 together with the superstructure 13 that it supported.Owing on the bottom surface of spherical slide block 11 polytetrafluoroethylene (PTFE) backing plate 12 is set, both contact fully in the process of sliding.Polytetrafluoroethylene (PTFE) backing plate 12 consumed energy in sliding process reduces the effect of seismic wave.Because the top of spherical slide block 11 is sphere, with the collet formation spherical hinge structure of bolster 10, this structure can guarantee that superstructure 13 remains level.The radius of sphere slideway 9 can be determined according to the shock insulation computation of Period.Sphere slideway 9 peripheries are vertical wall support 3, can not skid off bearing to guarantee spherical slide block 11, damage.As Fig. 3, under the effect of seismic wave flatly, superstructure slides with less pivot angle 14 in the sphere slideway 9 of base 5 together with the superstructure 13 that it supported, and only is out of shape superstructure 12 no changes of its support for the integral level displacement.
Under the effect of vertical seismic wave, disk spring 8 produces distortion, alleviating vertical ground seismic wave function, and the friction earthquake energy by 8 of disk springs.By the acting in conjunction of guide peg 1 and guide cylinder 2, limit the deformation direction of disk spring 8.The quantity of disk spring 8 and parameter can be determined according to calculating.Go up simultaneously further earthquake energy of visco-elastic damping material 7 that chamber interior fills in.
More than disclosed only be specific embodiment of the utility model; though the utility model discloses as above with preferred embodiment; but the utility model is not limited thereto; any those skilled in the art can think variation; in not breaking away from design philosophy of the present utility model and scope; the utility model is carried out various changes and retouching, all should drop within the protection domain of the present utility model.
