Description
Technical Field
The invention belongs to the technical field of building structure earthquake resistance, and particularly relates to a vertical inerter seismic isolation support.
Background
It is well known that the development of seismic isolation devices relies on the technological progress of dampers. At present, the dampers which really enter practical application are mainly classified into three major types, namely, a laminated rubber damper, a metal elastic member damper (mainly a disc-shaped elastic member and a spiral elastic member), and a viscoelastic damper (which cannot bear a large static load). Therefore, most of the existing vibration isolation supports are the combination of the dampers, and basically, the laminated rubber dampers and the metal elastic part dampers are connected in series up and down. In order to overcome the defects that laminated rubber is weak in tensile capacity, a disc-shaped elastic part cannot be pulled, a spiral elastic part is low in initial rigidity and different in tensile and compression characteristics, some shock insulation supports are additionally provided with tensile structures (such as steel wire ropes are additionally arranged on the periphery) of the laminated rubber damper, some shock insulation supports are also used for compounding a metal elastic part damper and a viscoelastic damper (or other stretchable materials, such as diamond-shaped steel plates and the like), the metal elastic part damper is used for bearing static load and compression shock absorption, and the viscoelastic damper is used for dissipating energy through stretching and compression. However, the damper with multiple elastic elements is complex in structure, and the horizontal and vertical correlation degree needs to be considered during design, so that the calculation is very complex.
In the design of a building structure, the earthquake-proof and shock-absorbing support can effectively reduce earthquake disasters; according to the requirements of national standard GB50011-2010 building earthquake-resistant design Specification, a rubber earthquake-resistant support is usually adopted as an earthquake-resistant device; under the action of earthquake, a building can generate larger horizontal displacement, and the amplitude of the horizontal displacement allowed by the existing support is smaller, so that the requirements of resisting large-intensity earthquake such as buildings, bridges and the like in engineering practice can not be met; the shock insulation support of medium and high-rise buildings usually needs to bear larger tensile force, but the existing shock insulation support has insufficient tensile capability and the application range is restricted; when the shock insulation support deforms due to displacement, the energy consumption performance is generally weak, and the earthquake action cannot be effectively weakened; in addition, after the earthquake acts, the self-resetting capability of the support is limited, so that the reuse of the support is influenced, and the economical efficiency is reduced; therefore, the vertical shock insulation support which can isolate the horizontal earthquake action, allows larger displacement, has better vertical tensile capacity and energy consumption performance is developed, and has important theoretical significance and practical application value.

Detailed Description
For a further understanding of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings and examples.
With reference to fig. 1, the vertical inerter seismic isolation bearing comprises a rotating mass block 3 arranged between a support structure 6 and a bearing structure 7, and a roller lead screw 4 arranged in the rotating mass block 3 in a penetrating manner, a lead screw nut 5 is arranged on the rotating mass block 3 at a position matched with the roller lead screw 4, two ends of the roller lead screw 4 respectively extend into the support structure 6 and the bearing structure 7, an upper rotary isolation layer 1 and a lower rotary isolation layer 2 are respectively arranged on the upper surface and the lower surface of the rotating mass block 3, and an elastic piece 8 is arranged between the upper rotary isolation layer 1 and the support structure 6.
Specifically, under the action of a vertical earthquake, the vertical inertial container vibration-isolating support disclosed by the invention drives the roller lead screw 4 to perform rotary motion relative to the lead screw nut 5 through the vertical motion of the supporting structure 6, and the lead screw nut 5 drives the rotating mass block 3 to rotate and generate damping force, so that the vibration-isolating energy consumption of the supporting structure 6 in the vertical direction is realized.
The seismic isolation support in the prior art usually has the effect of isolating a horizontal earthquake, and allows a supporting structure 6 to have larger displacement in the transverse direction, namely, when the earthquake comes, the seismic isolation support can play an effective buffering and energy consumption role on the transverse swing of a building, but the tensile capacity in the vertical direction is obviously insufficient and the energy consumption performance is poor, so that the fluctuation energy in the vertical direction of the building cannot be consumed in time, and the building collapses and is damaged under the continuous impact of earthquake fluctuation; the seismic isolation support with the vertical seismic isolation effect usually needs to consider the horizontal and vertical correlation degree, performs complex data calculation and structural design, and is not suitable for large-scale popularization and use in buildings.
According to the vertical inertial container shock insulation support, a screw rod system is matched with the rotating mass block 3, so that good transverse and vertical energy dissipation effects can be realized at the same time.
Further, in the embodiment, the lower rotary isolation layer 2 is arranged at the junction of the rotary mass block 3 and the bearing structure 7, and under the action of a horizontal earthquake, the lower rotary isolation layer 2 can generate large frictional resistance, so that the bearing structure 7 has good horizontal bearing capacity; go up rotation isolation layer 1 and set up between rotor mass piece 3 and bearing structure 6 and link to each other with the elastic component, screw-nut 5 links to each other with rotor mass piece 3, and under vertical earthquake effect, roller bearing lead screw 4 up-and-down motion drives rotor mass piece 3 through screw-nut 5 and produces great damping force, and it is clear and definite to pass power, can play better vertical shock insulation effect.
It is worth emphasizing that in the present embodiment, the roller screw 4 converts the linear relative motion between its two end points into the high-speed rotation motion of the screw nut 5, the roller screw system converts the axial translation acceleration into the rotation acceleration, and the element will generate the inertia acting force due to the existence of the rotational inertia of the rotating mass 3. Because the inertia effect generated by the rotational inertia of the rotating mass block 3 is far larger than that of the physical mass of the rotating mass block, the vertical inertial capacity shock isolation support can use smaller physical mass to generate larger inertia force, and achieves the effect of inertia synergy, namely the inertial capacity coefficient is far larger than the actual physical mass. This feature plays a very important role in structural control, and can significantly reduce the actual mass and mass of additional subsystems to save space and facilitate construction.
Therefore, the vertical inerter seismic isolation support has a vertical seismic isolation function, can simultaneously bear the horizontal seismic action and the vertical seismic action, is simple in structure, and is easy to mount and dismount.
