Description
Technical field
The utility model relates to a kind of building vibration proof (or vibrations) device, is specifically related to a kind of three-dimensional isolation device of being connected with the vertical earthquake isolating member by laminated steel and rubber pillow.
Background technology
Earthquake isolating equipment is provided in a side of the shockproof spacer assembly between building and the basis.Early stage earthquake isolating equipment mainly is by rubber and the steel sheet two-dimentional shock isolating pedestal that constitutes of layer that be superimposed, and can only isolate the horizontal component of seismic wave.Along with the raising of people to earthquake multidimensional characteristic understanding, three-dimensional isolation device is subjected to this area researcher's attention gradually.On January 5th, 2005 state know office disclose a kind of " three-dimensional isolation system " application for a patent for invention (publication number is: 1560395), the disclosed technical scheme of this patent application be on common laminated steel and rubber pillow series connection one by compound disk spring be located at the vertical cushioning members that the damper in the compound disk spring centre bore constitutes and form.The inventor of this technical scheme has only considered the pressure that earthquake " vertical component " is produced on shock isolating pedestal, and ignored the huge pulling force that waves even topple and produced of earthquake middle-high building thing, therefore do not consider tensile structure in the scheme, the tensile structure that has only is exactly the interior set damper of compound disk spring centre bore and the vulcanizing mold laminated structure of laminated steel and rubber pillow, obviously can't bear the huge pulling force that high-rise building topples and produced.On September 21st, 2005 state's " a kind of three-dimensional rubber earthquake isolation support " utility model patent of having known innings notice of authorization, the disclosed technical scheme of this patent is at common rubber, steel sheet is superimposed under the shock isolating pedestal, and series connection one vertical earthquake isolating bearing constitutes, the last joint cover and the base (steel bushing 2) that it is characterized in that described vertical earthquake isolating bearing constitute a piston rod structure, be provided with the resilient rubbber cushion (vertical earthquake isolating plate 1) that is superimposed by rubber and steel sheet in the cavity volume of cylinder body, wherein said joint cover and steel bushing play the guiding role, the vertical earthquake isolating plate plays damping action, and The combined gets up to eliminate the vertical component of the seismic wave that is come by the ground transmission.This shows that this utility model do not have tensile structure yet, can not resist the huge pulling force that waves even topple and produced of earthquake middle-high building thing.
Summary of the invention
In view of there is above-mentioned deficiency in prior art, technical problem to be solved in the utility model is to improve the tensile strength of three-dimensional isolation device, to resist the huge pulling force that waves even topple and produced of earthquake middle-high building thing.
The technical solution that the utility model solves the problems of the technologies described above is:
A kind of novel three-dimensional earthquake isolating equipment, this device is connected in series with the vertical earthquake isolating member by laminated rubber damping bearing and constitutes, the rubber pad that it is characterized in that described laminated rubber damping bearing is interior around uniform at least three the flexible tension members of symmetrical centre wire loop, the middle bent of this flexibility tension member places in the centre bore of rubber pad, and two is fixed on the both ends of the surface up and down of rubber pad; The spread length of described flexible tension member is not more than the tensile elasticity deflection of rubber pad; The following joint cover of described laminated rubber damping bearing is located on the ring spring, and the annular edge of a wing that extends internally, the upper end of described fairlead will connect integrated circuit board within it down, be provided with the loop buffer pad between the annular edge of a wing and the following joint cover.
In the technique scheme, the complete stretching state length that the spread length of described flexible tension member equals flexible tension member deducts case of bending length poor of flexible tension member.
The new described annular edge of a wing of this practicality is to be welded on the fairlead upper end by Yi Kagai to constitute.
Flexible tension member described in the utility model is a wire rope, and the middle part free bend places in the centre bore of rubber pad.
The both ends of the surface up and down of rubber pad described in the utility model are provided with the envelope steel plate, are provided with aperture round symmetrical centre on it, and two of flexible tension member is welded on respectively on its outer face after passing through described aperture.
Three-dimensional isolation device described in the utility model has been made following 2 significant improvement than prior art, the one, be provided with flexible tension member in the rubber pad of laminated rubber damping bearing, two of this member is fixed on the both ends of the surface up and down of rubber pad, and the spread length of flexible tension member is not more than the tensile elasticity deflection of rubber pad, therefore whole shock isolating pedestal horizontal distortion amount and on draw deflection all in the scope of design of rubber pad, described flexible tension member is in free extended configuration, in case scope of design near rubber pad, flexible tension member promptly is straightened, enter the tension guard mode, bear all external broach, thereby protect the overall structure of rubber pad and laminated rubber damping bearing not to be destroyed effectively; The 2nd, the annular edge of a wing that extends internally, the upper end of described fairlead will connect integrated circuit board in fairlead down, and go up between the annular edge of a wing and the following joint cover and be provided with the loop buffer pad, constitute a tensile structure, this tensile structure both provided the structure with tension effect for the vertical earthquake isolating member, had also eliminated the bump that vertical vibrations produced.This shows that three-dimensional isolation device described in the utility model can improve the anti-ability of waving even toppling of high-rise building greatly.
