Description
Technical Field
The utility model relates to the technical field of building structures, in particular to a device capable of vertically and horizontally isolating vibration for a building.
Background
With the rapid development of rail transit including high-speed rail and subways and the continuous encryption of urban rail transit networks, more and more construction projects cannot avoid adjacent or crossing rail transit. According to the statistical data of subway vibration of Beijing, Shanghai and Guangzhou, the ground vibration induced by the subway is mainly vertical vibration. For buildings adjacent to rail transit, when vertical vibration exceeds the national regulation limit, necessary vibration reduction measures are required, especially for buildings with high vibration requirements, such as theaters, concert halls, museums, sophisticated laboratories and the like. Environmental vibration and noise control has become a problem that must be addressed in building structure design.
Earthquake is a natural phenomenon which cannot be avoided by human beings. Under the action of earthquake, the building can be greatly horizontally deformed and even collapsed. The shock insulation technology achieves the shock absorption purpose by prolonging the self-vibration period of the structure, and after the shock insulation technology is adopted, the shock resistance of the building is obviously improved, so that the shock insulation system is suitable for various buildings such as disaster prevention and relief buildings, school buildings, important infrastructure buildings, houses, offices and the like in high-intensity earthquake areas. The seismic isolation technology is one of the most effective means for relieving earthquake disasters, and the seismic isolation technology really makes it possible that a building does not collapse in an earthquake.
The spring-added damper vibration isolator is an important means for controlling vertical vibration, however, because the allowable horizontal limit deformation of the spring vibration isolator is very small and is generally only 20-50 mm, when the allowable horizontal limit deformation is exceeded, the vertical bearing performance of the spring is sharply reduced, and the control of the horizontal deformation of the spring vibration isolator not exceeding the limit value is a crucial factor for influencing engineering safety. In non-seismic areas, the horizontal deformation of the building is small, and the vertical vibration of the structure can be reduced by adopting the spring vibration isolator. In the earthquake region, the earthquake action can cause larger horizontal deformation of the building, and when the spring vibration isolator is adopted to reduce the vertical vibration of the structure, other measures are needed to be set, so that the horizontal deformation of the spring vibration isolator is controlled within an allowable range.
At present, when a spring vibration isolator is adopted in a seismic region to control vertical vibration, a viscous damper is adopted to control the horizontal deformation of the spring vibration isolator, namely, the damper is arranged on a vibration isolation layer, the deformation of the vibration isolation layer is reduced through the energy consumption of the damper, the horizontal deformation of the spring vibration isolator is controlled within a limit value range, and meanwhile, the vertical vibration damping effect of the spring vibration isolator is not influenced. Because the allowed horizontal displacement of the spring vibration isolator is small, a viscous damper with a large tonnage is needed to limit the displacement of the vibration isolation layer within the displacement limit value of the spring vibration isolator. The large-tonnage damper not only has high manufacturing cost, but also has large internal force of the components at the joint, complex connection structure and limited reliability. Meanwhile, the displacement of the vibration isolation layer is limited within a very small range through the damper, the horizontal equivalent stiffness of the vibration isolation layer is large, the seismic effect transmitted to the upper structure cannot be effectively reduced, the vibration isolation effect is poor, and the ideal target of vertical vibration and horizontal seismic double isolation is difficult to achieve.

Example two
The second embodiment provides a method for vertical vibration isolation and horizontal vibration isolation for buildings, the second embodiment is another technical scheme of adding a method on the basis of the first embodiment, technical features disclosed by the first embodiment are also applicable to the second embodiment, and technical features disclosed by the first embodiment are not described repeatedly.
The embodiment provides a method for vertical vibration isolation and horizontal vibration isolation for a building, which comprises the following steps:
the device which can isolate the vertical vibration and the horizontal vibration for the building of the first embodiment is adopted between the upper building structure 102 and the lower building structure 304;
the vibration in the vertical direction is reduced by the vertical vibration isolation mechanism 20;
the horizontal vibration isolation mechanism reduces the vibration in the horizontal direction and restricts the horizontal deformation of the vertical vibration isolation mechanism 20.
When vertical static load of a building and environment have vertical vibration, the transmission path of the vertical force is as follows: the upper building structure 102 → the top plate 103 of the friction pendulum support → the bottom plate 101 of the friction pendulum support → the first baffle layer 203 on the inner side → the inner shock absorbing layer 204 → the inner glide layer 205 → the second baffle layer 206 on the outer side → the outer shock absorbing layer 207 → the first baffle layer 208 on the outer side → the stiffening plate 401 on the outer side → the top plate of the fixing means 30 → the vertical rib → the bottom plate of the fixing means 30 → the lower building structure 304 of the building; thereby achieving relative deformation of the upper building structure 102 and the lower building structure 304 in the horizontal direction and isolating the transmission of horizontal seismic action to the upper building structure 102. The device not only can reduce vertical vibration, but also can ensure that the spring 201 vertically bears, and the horizontal action of the isolated earthquake is transmitted to the upper building structure 102, thereby achieving the purpose of reducing the vertical vibration and the horizontal earthquake action of the upper building structure 102.
Under the action of an earthquake, the spring 201 is firstly horizontally deformed, when the horizontal deformation of the spring 201 reaches the gap width, the first horizontal shock isolation mechanism plays a role of limiting the deformation of the spring 201, and the transmission path of the horizontal force generated by the earthquake is the inner first baffle layer 203 → the inner shock absorption layer 204 → the inner sliding layer 205 → the outer second baffle layer 206 → the outer shock absorption layer 207 → the outer first baffle layer 208 → the outer stiffening plate 401 → the top plate of the fixing mechanism 30 → the vertical rib plate 303 → the bottom plate of the fixing mechanism 30. The first horizontal shock isolation mechanism limits the horizontal deformation of the spring 201, guarantees the vertical bearing of the spring 201, and meanwhile achieves the effective transmission of earthquake horizontal force, and meanwhile, due to the arrangement of the inner side shock absorption layer 204 and the outer side shock absorption layer 207, the purposes of energy absorption and shock absorption are achieved, and therefore the influence of horizontal direction shock is reduced.
By arranging the limiting device between the upper connecting plate 301 and the lower connecting plate 302, horizontal loads such as horizontal earthquake action are directly transmitted through the limiting device, the spring 201 of the spring 201 support does not bear the horizontal loads, horizontal deformation does not occur or a small amount of allowable deformation of the spring 201 occurs, and the problem that a conventional spring 201 vibration isolator cannot bear large horizontal force and is poor in horizontal deformation capacity is solved. Vertical vibration is isolated through the spring 201 with high bearing capacity, the vertical rigidity and the bearing capacity of the support are only determined by the spring 201 with high bearing capacity, and the vertical rigidity and the bearing capacity are not generated by other components. The shaped friction pendulum vibration isolation support is arranged at the top of the support vibration isolation mechanism, so that the horizontal period of the structure is prolonged, the horizontal earthquake effect is reduced, and horizontal vibration isolation is realized.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
