Abstract
The present invention discloses an anti-lifting device for an earth quake isolator, which is composed of an upper cover plate, a sleeve barrel and a cylindrical block, wherein the bottom of the upper cover plate and the top of the sleeve barrel are connected into a whole. The sleeve barrel is sheathed on the cylindrical block, and the sleeve barrel and the cylindrical block form sliding fit. A plurality of blind holes which are corresponding one to one are arranged between the upper cover plate and the cylindrical block, and elastic elements are arranged in the blind holes. A plurality of holes are longitudinally arranged between the upper cover plate and the cylindrical block, and guide plugs are arranged in the upper cover plate and the cylindrical block; the plugs and the holes form sliding fit. The present invention can be effectively matched with a shock absorption energy absorbing device, and can protect the safety of a vibration isolator under the lifting function of the earthquake. The purpose of protecting the building from being damaged can be obtained. The present invention has the advantages of simple structure, practicality, low cost and favourable effect. The present invention is suitable for multiform vibration isolators of a rubber shock insulation pad type, a rolling ball type, a sliding plate type, a rail type, etc.
Description
Technical field
The present invention relates to a kind ofly anti-lift from device, relate in particular to a kind of earthquake isolator with preventing lifting from device.
Background technology
Earthquake causes great destruction to building, and the earthquake isolator is a kind of effective earthquake damper facility.Isolator was subjected to the ground seismic wave function of three direction six degree of freedoms when usually, earthquake took place.By isolation and the energy dissipating effect of isolator, thereby reach with the not impaired effect of protection building to seismic wave.Yet, sometimes also can be except the horizontal shear effect when earthquake takes place to the bigger effect of vertically lifting from of isolator generation, tend to cause the earthquake isolator impaired because of drawing crack or impact.
Summary of the invention
The present invention realizes by following scheme: be made of upper cover plate, sleeve and cylindrical piece, the bottom of upper cover plate and sleeve top are connected as a body, sleeve is placed on the cylindrical piece, between the two for being slidingly matched, be provided with several blind holes one to one between upper cover plate and the cylindrical piece, be provided with flexible member in the blind hole.Blind hole is evenly arranged.
For preventing that upper cover plate sleeve of the present invention and cylinder along continuous straight runs from reversing, between upper cover plate and cylindrical piece, vertically be provided with several holes, in establish the guiding latch, between latch and hole for being slidingly matched.Can only slide up and down between upper cover plate sleeve and the cylindrical piece like this and be unlikely to produce and reverse.
Flexible member of the present invention can be common rigidity steel wire, leaf spring, the shape spring etc. of talking endlessly, and also can be flexible resilient element, elastic caoutchouc, elastoplast, elastic sponge etc.
Upper cover plate of the present invention and sleeve can divide body formed or be shaped to one.
The present invention can effectively cooperate the shock-damping energy-dissipating device to play the effect of isolation energy dissipation, reaches the unlikely impaired purpose of protection building.The present invention is simple in structure, practical, cost is low, effective, be applicable to the isolator of various ways such as rubber vibration isolation cushion, bobbin type, slide type, rail mounted.
Description of drawings
Fig. 1 is the embodiment of the invention 1 structural representation;
Fig. 2 is the embodiment of the invention 2 structural representations;
Fig. 3 is the generalized section of the present invention and rubber isolator combination embodiment.
The specific embodiment
The present invention is described in detail below in conjunction with the embodiment accompanying drawing.
Embodiment 1:
Referring to Fig. 1, present embodiment is made of with cylindrical piece 3 upper cover plate 1, sleeve 2, the bottom of upper cover plate 1 and sleeve 2 top group integrators, sleeve 2 is placed on the cylindrical piece 3, between the two for being slidingly matched, be provided with 8 blind holes 4 one to one between upper cover plate 1 and the cylindrical piece 3, be provided with flexible member 5 flexible members 5 in the blind hole 4 and be wire spring.Upper cover plate 1 and sleeve 2 minutes are body formed.
Embodiment 2:
Referring to Fig. 2, present embodiment is made of with cylindrical piece 3 upper cover plate 1, sleeve 2, the bottom of upper cover plate 1 and sleeve 2 tops are connected as a body, sleeve 2 is placed on the cylindrical piece 3, between the two for being slidingly matched, be provided with 6 blind holes 4 one to one between upper cover plate 1 and the cylindrical piece 3, be provided with flexible member 5 in the blind hole 4 to play the energy dissipating effect.Vertically be provided with 6 holes 6 between upper cover plate 1 and the cylindrical piece 3, in establish guiding latch 7,6 in latch 7 and hole are for being slidingly matched.
Operating principle of the present invention is: the upper cover plate and the cylindrical piece of the present invention 2 of isolator are connected as a single entity, and the lower shoe of isolator is connected with the building superstructure of the basis of building or interlayer shock insulation mode.Upper cover plate 1 of the present invention is connected with the bottom of building or the building bottom of interlayer shock insulation mode.The energy that produces when earthquake takes place is to propagate to diffusion all around from the earthquake centre with the form of compressional wave (P ripple) and shear wave (S ripple), can produce the motion of three degree of freedom 6 coordinates after building is shaken.Because the base plate of isolator is connected with the bottom of building foundation or interlayer shock insulation layer, whole assembly structure anti-lifts from the bottom of device upper cover plate and building or the top of interlayer shock insulation layer is connected as a single entity.Therefore, under the effect of seismic wave, can produce each between the top of building and the bottom or between the bottom of building and the basis to relative motion.When up and down between the two when generation level or twist motion, because building by the flexible working aspect of isolator, can reach isolating affection by the relative displacement that its distortion produces the top and the bottom horizontal direction.The present invention can effectively cooperate the shock-damping energy-dissipating device to play the protection isolator to lift from safety under the effect in earthquake, reach the unlikely impaired purpose of protection building.The generation vertical direction lifts from when moving when building is shaken, can produce between the sleeve of the at this moment anti-upper cover plate of lifting from device and the rigid cylindrical body and slide up and down, flexible member in the blind hole can make the anti-rigid cylindrical body of lifting from device tightly be pressed together on all kinds of isolators such as rubber vibration isolation cushion, makes isolator not be subjected to the pulling force of vertical direction all the time.And building is when falling, and each flexible member can also play the momentum that produces when cushioning effect falls because of building to slow down, and plays the effect of protecting isolator.
Embodiment 3:
Fig. 3 is with the anti-generalized section of lifting from device and rubber isolator combination embodiment of earthquake isolator.Earthquake isolator of the present invention is identical with embodiment 2 with preventing lifting from apparatus structure.It is identical that the earthquake of the isolator of other type such as slide type, bobbin type, rail mounted isolator prevents lifting from principle, do not exemplify one by one at this.
