[0003] At present, viscous dampers, metal yield type dampers and buckling restrained energy dissipation supports mainly absorb and dissipate energy through linear displacement, and there are few damper devices that absorb and dissipate energy through angular displacement. Under the action of vertical wind, earthquake and the like, the cantilever part of special structures such as large cantilever structures and suspended structures will produce large vertical response, including vertical linear displacement and angular displacement. In addition to the energy dissipation damper relying on linear displacement, the energy dissipation damper relying on angular displacement can also be used. The energy dissipation damper relying on angular displacement is called angular displacement damper. On the other hand, under the same wind and earthquake action, amplifying displacement thread, including circular arc displacement thread and angular displacement thread, can improve the energy dissipation efficiency of angular displacement damper.

[0004] Therefore, providing an angular displacement damper device with thread amplification function can fill the gap in the field of building engineering. SUMMARY

[0036] Furthermore, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0037] Example 1

[0038] Figure 1 , Figure 2 In the illustrated embodiment, an angular displacement damper device with thread amplification function includes a floor 1, a wall 2, a connecting device 3, a thread amplification device 4, a guide rod 5, an arc angular displacement damper 6, and a damper support beam 7.

[0039] The floor surface 1 is connected to the floor lug 31 in the connecting device 3. Inside the connecting device 3, the floor lug 31 is connected to the force-transmitting vertical rod 32, and the force-transmitting vertical rod 32 is connected to the short lever lug 33. When the floor surface 1 generates a vertical angular displacement, the floor surface 1 transmits the angular displacement to the connecting device 3. The angular displacement transmission path in the connecting device 3 is as follows: floor surface 1 → floor lug 31 → force-transmitting vertical rod 32 → short lever lug 33.

[0040] The short lever lug 33 in the connecting device 3 is then connected to the short lever 41 in the thread amplification device 4. Inside the thread amplification device 4, the short lever 41 and the torsion beam 42 are orthogonally rigidly connected. The torsion beam 42 is supported by the torsion beam support beam 44, which allows it to rotate freely. The torsion beam support beam 44 is supported by a wall. The torsion beam 42 and the long lever 43 are orthogonally rigidly connected. The short lever lug 33 in the connecting device 3 transmits angular displacement to the short lever 41 in the thread amplification device 4. The transmission path of the angular displacement in the thread amplification device 4 is as follows: short lever lug 33 in the connecting device 3 → short lever 41 → torsion beam 42 → long lever 43.

[0041] In the thread amplification device 4, the long lever 43 is connected to the guide rod 5, and the guide rod 5 is connected to the arc angle displacement damper 6. The arc angle displacement damper is supported by the damper support beam 7, and the damper support beam 7 is supported by the wall 2.

[0042] Under the influence of vertical wind, earthquake, etc., the floor 1 generates vertical angular displacement. The floor 1 transmits the vertical angular displacement to the linear amplification device 4 through the connecting device 3. The linear amplification device 4 amplifies the angular displacement and linear displacement and transmits them to the guide rod 5. The guide rod reciprocates within the arc angular displacement damper 6, which plays a role in energy dissipation.

[0043] The working mechanism of the thread amplification device 4 is as follows: the distance from the axis of the vertical support in the connecting device 3 to the wall is defined as 'a', the length of the short lever 41 in the thread amplification device 4 is defined as 'b', and the length of the long lever 43 in the thread amplification device is defined as 'c', where b < a and b < c. Figure 3 As shown, when the floor 1 experiences an angular displacement a1 (clockwise) or a2 (counterclockwise), the connecting device 3 experiences a vertical displacement. Since b < a, under the same vertical angular displacement, the short lever 41 of the thread amplification device 4 causes a larger angular displacement b1 and b2 to the torsion beam 42 of the thread amplification device 4 than the floor 1, resulting in an angular displacement amplification effect. Since b < c, under the same angular displacement, due to the lever principle, the end of the long lever 43 of the thread amplification device 4 (the position where the long lever 43 and the guide rod 5 are connected) generates a larger vertical in-plane arc displacement than the end of the short lever 41 of the angular displacement amplification device (the position where the short lever 41 and the short lever ear plate 33 are connected), resulting in a linear displacement amplification effect. Therefore, the function of the thread amplification device 4 includes the amplification effects of angular displacement and linear displacement. The thread amplification device 4 then transmits the amplified angular displacement and linear displacement to the guide rod 5, and finally, the guide rod 5 reciprocates in the arc angular displacement damper 6, achieving a better energy dissipation effect.

[0044] The embodiments are examples and not limitations. Wall 2 can also be implemented with columns, and floor 1 can include floor slabs, beams or only floor slabs.

Its basic structure and principle are the same as in Example 1.

[0048] Figure 5 This is a schematic diagram of a third form of an angular displacement damper device with thread amplification function, shown in plan view. The circular arc angular displacement damper 6 is a long box shape on the plane. Its basic structure and principle are the same as those in Example 1.

[0049] The above description is merely a description of preferred embodiments of this application and is not intended to limit the scope of this application in any way. Any changes or modifications made by those skilled in the art based on the above-disclosed technical content should be considered as equivalent and valid embodiments and fall within the scope of protection of the technical solution of this application.
