Abstract
The utility model discloses a lifting preventing device for an earthquake shock isolator, comprising an upper cover board, a sleeve, and a column block. The bottom of the upper cover board is connected with the top of the sleeve which sheathes the column block; the sleeve and the column block can slide relatively; a plurality of one-to-one dead holes are arranged between the upper cover board and the column block and each dead hole is provided with a spring element inside. A plurality of holes are arranged between the upper cover board and the column block in the longitudinal direction and guide bolts are arranged in the holes; the guide bolts can slide relative to the holds. The utility model, effectively matching with a shock absorbing and energy dissipating device, can protect the shock isolator in earthquake lifting, reaching the purpose of protecting the buildings. With simple structure, low cost good performance and practicality, the utility model is suitable for various shock isolators as the rubber pad isolator, the rolling-ball isolator, the slide plate isolator and the rail-style isolator.
Description
Technical field
The utility model relates to a kind ofly anti-lifts from device, relates 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 utility model is realized 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 utility model 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 described in the utility model 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.
But upper cover plate described in the utility model and sleeve split are shaped or are configured as one.
The utility model 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 utility model 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 utility model embodiment 1 structural representation;
Fig. 2 is the utility model embodiment 2 structural representations;
Fig. 3 is the generalized section of the utility model and rubber isolator combination embodiment.
The specific embodiment
Below in conjunction with the embodiment accompanying drawing the utility model is elaborated.
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 is shaped with sleeve 2 splits.
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 utility model is: the upper cover plate and the cylindrical piece of the present utility model 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 utility model 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 utility model 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 utility model 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.
