[0002] Airport control towers are critical infrastructure responsible for guiding aircraft takeoffs and landings. Various air traffic control equipment is deployed on the control layer. Given the frequent earthquakes in my country, ensuring the seismic safety of control tower equipment is crucial. Currently, the seismic design of control tower structures has the following problems:

[0003] Control towers play a crucial role in emergency rescue during earthquakes. When an earthquake strikes, they must not only ensure the main structure of the control tower remains intact but also guarantee the normal operation of various air traffic control equipment on the control level. However, currently, the working platforms housing the air traffic control equipment on the control level are rigidly connected to the floor slab. Under earthquake conditions, the air traffic control equipment on these platforms is easily damaged and rendered inoperable. Furthermore, earthquakes act bidirectionally along both the X and Y axes on the working platforms, and currently, there are no bidirectional seismic isolation working platforms available.

The rubber pad 33 and the steel plate pad 34 are alternately arranged on the outside of the internal lead core 31. The protective rubber layer 36 surrounds the outside of the rubber pad 33 and the steel plate pad 34. The upper connecting steel plate 32 and the lower connecting steel plate 35 are both horizontally arranged and connected to the upper and lower ends of the internal lead core 31 and the protective rubber layer 36, respectively. The outer parts of the upper connecting steel plate 32 and the lower connecting steel plate 35 are respectively provided with multiple lower connecting holes 37, wherein the multiple lower connecting holes 37 on the upper connecting steel plate 32 correspond to the multiple upper connecting holes 24 on the bottom connecting plate 23 and are connected to each other by bolts 25.

[0023] The working principle of the two-way seismic isolation working platform for the control tower provided by this utility model is that when an earthquake occurs, the lead-core rubber support 3 located at the bottom will extend the natural vibration period of the platform through shear deformation in the horizontal X and Y directions, thereby reducing the seismic energy of the platform; the damping layer 4 located at the top will deform to dissipate or absorb the seismic energy in the horizontal X and Y directions, so as to reduce the seismic response of the platform and thus avoid damage to the platform and air traffic control equipment.
