Background technology
Isolation structure is to set one layer between the superstructure and substructure of building to have sufficiently flexible and power consumption
Seismic Isolation of Isolation Layer, transmitted for obstructing seismic energy to superstructure., can be by isolation structure according to the difference of Seismic Isolation of Isolation Layer present position
It is divided into base isolation and Interlayer seismic isolation.The general same layer of Seismic Isolation of Isolation Layer, general same absolute altitude during with layer, difference during even if absolute altitude difference
It is smaller.
For Interlayer seismic isolation layer, because elevator needs landing, elevator rail can not hinder the deformation of Seismic Isolation of Isolation Layer, it need to be entered
Row particular design.Existing solution mainly has two kinds：
A kind of scheme is to use suspension type elevator rail, is elevator periphery and shock insulation branch by increasing core cylinder size
Sufficient space is reserved at seat, to meet Seismic Isolation of Isolation Layer deformation, maintenance and clear up；
Another scheme is to interrupt elevator rail in Seismic Isolation of Isolation Layer, and connects replacement using memorial alloy, serves as Seismic Isolation of Isolation Layer
The elevator rail in region.The program need not increase core cylinder size, but program elevator is forced stopping in coming earthquake and made
With after earthquake terminates, elevator recovers normally to use, or can be used by repairing rear；
Former scheme takes excessive building and uses space, and latter scheme does not produce influence, but elevator on building arrangements
It is forced to stop using in coming earthquake.
The content of the invention
It is an object of the invention to provide a kind of new mixing Interlayer seismic isolation system, its can not only ensure core cylinder size without

On, and can the relatively U-shaped level of frame 11 slip.
To sum up, new mixing Interlayer seismic isolation system of the invention, because the first Seismic Isolation of Isolation Layer 4 and the second Seismic Isolation of Isolation Layer 5 are arranged on
The second aseismic joint 6 is provided between different level, and floor and Core Walls Structure 3 of second Seismic Isolation of Isolation Layer below 4, so, not only Core Walls Structure 3
Size without expanding, vertical traffic main artery is not interrupted in Core Walls Structure 3, and to the building arrangements of the second Seismic Isolation of Isolation Layer more than 4 not
Influence can be produced, the influence produced to building arrangements of second Seismic Isolation of Isolation Layer below 4 is also smaller；Again due to the first Seismic Isolation of Isolation Layer 5 and core
There is the first aseismic joint 7 in the peripheral sidewalls of the bottom of heart cylinder 3, be that moving horizontally for Core Walls Structure 3 leaves enough spaces so that
Core Walls Structure 3 of second Seismic Isolation of Isolation Layer below 4 can follow upper floor to move together.
It the above is only the preferred embodiment of the present invention, it is noted that come for those skilled in the art
Say, without departing from the technical principles of the invention, some improvement and replacement can also be made, these, which improve and replaced, also should
It is considered as protection scope of the present invention.
