Description
The utility model relates to the field of building vibration isolation, in particular to a multidirectional composite vibration isolation support.
Background
Earthquake is a sudden and destructive natural disaster. Under the action of earthquake, the building structure is easy to be damaged in various forms such as bending, shearing, torsion and the like, and excessive plastic deformation is generated. In general, building structures collapse due to insufficient deformability. The seismic isolation technique is an effective way to avoid or mitigate the damage to the building structure from seismic events by providing a seismic isolation layer or mounting a seismic isolation mount between the foundation and the superstructure to reduce the transmission of seismic energy into the superstructure, thereby reducing the seismic impact of the structure. Rubber mounts have been used in engineering as conventional shock mounts and have been demonstrated to reduce seismic effects to some extent.
However, the rubber shock insulation support has the defects of limited deformability and small elastic range, is easy to generate excessive plastic deformation under the action of strong shock, brings great difficulty to post-shock repair work, sometimes even causes the building structure to be overturned and destroyed so as not to be repaired, and therefore, the rubber shock insulation support lacks self-resetting capability and cannot meet the requirement of structural toughness shock-resistant design. On the other hand, a great deal of researches show that the earthquake action is very complex, the peak value of the vertical vibration acceleration can reach 1/3-1/2 of the horizontal acceleration, and the vertical earthquake action has important influence on the earthquake resistance of the building structure; in addition, the seismic wave monitoring data show that the effect of the earthquake on the building structure is characterized by multiple directions. The existing shock insulation supports can only insulate the horizontal earthquake action, but cannot simultaneously cope with the vertical earthquake action. Therefore, it is necessary to invent a novel shock insulation support which has strong self-resetting capability, replaceability and is capable of coping with multi-directional earthquake actions.
The utility model of China with publication number of CN102191817A discloses a lead rubber shock insulation support, which comprises at least four main internal thread sleeves pre-buried in an upper buttress of a building, an upper pre-buried steel plate fixed on the bottom surface of the upper buttress, an upper connecting steel plate, a lead rubber shock insulation support body, a lower connecting steel plate, a lower pre-buried steel plate fixed on the top surface of a lower buttress of the building, various mechanical connecting fasteners, bolts and other components. Although the shock insulation support has good replaceable capability, the problem of toppling of a superstructure, which is easily caused by excessive plastic deformation of a shock insulation layer after a major shock, is difficult to avoid due to limited elasticity of the rubber shock insulation support.
The Chinese patent of utility model with publication number of CN209293226U discloses a tensile laminated rubber shock insulation support, which comprises an upper connecting plate, a lower connecting plate, a steel wire rope and a laminated rubber elastomer, wherein the steel wire rope is arranged between the upper connecting plate and the lower connecting plate, steel balls are arranged at two ends of the steel wire rope, when strong shearing force generated by an earthquake is transferred to the upper connecting plate and the lower connecting plate, one end of the steel ball on the steel wire rope is locked along with relative displacement of the upper connecting plate and the lower connecting plate, and the other end of the steel ball slides, so that the steel wire rope is kept in a tight state, and when the external force is eliminated after the earthquake is finished, the steel wire rope is restored to the original state. When the laminated rubber elastic body is compressed and shortened under the pressure, the steel wire rope is changed into a loose state from a tight state, the steel ball can slide freely, and the pressure is borne by the laminated rubber elastic body; when the steel ball is pulled, the steel ball is locked on the groove, the steel wire rope immediately enters a working state, and the tensile force transmitted by the upper connecting plate and the lower connecting plate is shared, so that the shock insulation and tensile requirements of high-rise buildings can be better met. However, the shock insulation support cannot well insulate the vertical earthquake action, and lacks effectiveness on multidimensional earthquake action. And, because this support uses independent stromatolite rubber shock insulation support as the main part, consequently to the major earthquake, the too big plastic deformation that causes after the major earthquake can not be fine eliminated, consequently to the long-term use of main part structure unfavorable, can not satisfy the high toughness demand of shock insulation structure well. In addition, the support device of the shock insulation support cannot be well replaced, so that the shock insulation structure is easily damaged due to the earthquake action and other various environmental factors in the long-term use process, the shock insulation capacity is reduced, and the toughness requirement of the shock insulation structure cannot be met.
The Chinese patent of the utility model with the publication number of CN215764031U discloses a three-dimensional shock-insulation support, which comprises a bottom connecting plate, a top connecting plate, a shock-insulation unit lower connecting plate, a shock-insulation unit upper connecting plate and various connecting devices, the shock insulation and noise reduction functions can be achieved at ordinary times, the vibration and noise of equipment are greatly reduced, the noise pollution is remarkably reduced, when the three-dimensional shock-insulation support and an object borne on the three-dimensional shock-insulation support are subjected to the earthquake action, the three-dimensional shock-insulation support realizes the vertical shock insulation action through the vertical extension and contraction of an elastic support, the three-dimensional shock-insulation support realizes the horizontal shock insulation action through the elastic deformation of the elastic support in the horizontal direction, the shock insulation effect and the amplitude are realized through the vertical rigidity and the horizontal rigidity of a matched spring, the three-dimensional shock-insulation support can overcome the defects of the traditional horizontal shock-insulation support to a certain extent, but the vertical tension caused by the vertical earthquake action can not be well solved, and the support can be broken by tension due to the insufficient tension, so that the requirement of a high-toughness shock-insulation structure can not be met for long-term use of the shock-insulation support.
In summary, the present seismic isolation technology has the following drawbacks and disadvantages:
1. the traditional horizontal rubber shock insulation support has the defects of poor deformation capability and weak self-resetting capability, and is easy to generate larger plastic deformation under strong shock, so that an engineering structure is overturned and damaged; in addition, the service life of the shock insulation support is reduced due to weak self-resetting capability, and great difficulty is brought to post-earthquake repair, so that a novel shock insulation support with strong self-resetting capability is required.
2. Although the existing three-dimensional vibration isolation support can improve the effectiveness of the vibration isolation capability of the multi-dimensional earthquake to a certain extent, the anti-pulling design is not performed on the vertical pulling force caused by the vertical earthquake, so that the support can be pulled to be damaged, the vibration isolation support is invalid and loses the use function, and the anti-pulling design is performed on the vibration isolation support simultaneously on the basis of considering the three-dimensional earthquake effect, so that the toughness and the tensile capability of the three-dimensional vibration isolation support are improved.
