Description

Technical Field

[0001] This invention relates to the field of yield damper technology, and specifically to a two-stage metallic yield damper. Background Technology

[0002] Building dampers are safety devices installed on buildings to mitigate earthquake damage. They are widely used in civil buildings, industrial buildings, and bridges. When an earthquake occurs, the damping wall absorbs and dissipates the impact energy of the earthquake on the building structure to the maximum extent, greatly mitigating the impact and damage of the earthquake on the building structure.

[0003] Yielding dampers are devices that dissipate seismic energy through a metal yielding process. They typically possess high energy dissipation capacity and stable hysteretic performance, effectively reducing the seismic response of structures. However, existing yielding dampers generally consist of only a single core plate, resulting in poor seismic resistance. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a two-stage metal yielding damper, which can effectively solve the problem of poor seismic performance caused by a single core plate in the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a two-stage metal yielding damper, including a base plate, and further comprising: A multi-stage seismic-resistant component includes a first core plate mounted on a base plate, a connecting plate mounted on top of the first core plate, and a second core plate mounted on top of the connecting plate; The auxiliary resistance component includes two limiting frames slidably mounted on a base plate. Each of the two limiting frames has a sliding frame slidably mounted on it, and the top of the sliding frame is in full contact with the bottom of the connecting plate. A trapezoidal frame is slidably mounted on the base plate, and a lifting member is provided between the trapezoidal frame and the sliding frame. When the connecting plate squeezes the sliding frame downward, the lifting member resists the downward movement of the sliding frame.

[0006] Furthermore, a first side plate is fixedly installed on both outer walls of the first core board, a second side plate is fixedly installed on both outer walls of the second core board, and a top plate is fixedly installed on the top wall of the second core board.

[0007] Furthermore, the limiting frame is provided with a sliding groove, the sliding frame is slidably installed in the sliding groove, a support plate is fixedly installed on the side of the sliding frame near the connecting plate, the lifting member includes a slider slidably installed on the trapezoidal frame, a first piston tube is fixedly installed on the slider, a first piston rod is movably inserted into the top of the first piston tube, the first piston rod is fixedly connected to the bottom wall of the sliding frame, and a first return spring is provided in the first piston tube.

[0008] Furthermore, the lifting component also includes a second piston tube fixedly installed on the side of the trapezoidal frame near the first core plate, a second piston rod movably inserted on the second piston tube, and the second piston rod is fixedly connected to the limiting frame, and the second piston tube and the first piston tube are connected to each other.

[0009] Furthermore, two baffles are symmetrically fixedly installed on the top of the support plate, and the distance between the two baffles is slightly greater than the width of the connecting plate.

[0010] Furthermore, an mounting plate is fixedly installed on the inner wall of the limiting frame, a third piston tube is fixedly installed on the mounting plate, a third piston rod is movably inserted into the top of the third piston tube, an auxiliary plate is fixedly installed on the top of the third piston rod, and the auxiliary plate, the third piston tube and the first piston tube are connected.

[0011] Furthermore, an air box is fixedly installed on the mounting plate, a fourth piston rod is movably inserted into the top of the air box, a push plate is elastically connected to the top of the fourth piston rod, and the push plate is slidably connected to the side wall of the limiting frame.

[0012] Furthermore, the limiting frame is provided with an inclined groove, and the push plate is slidably installed in the inclined groove. When the push plate moves up, it moves closer to the second core plate along the inclined groove.

[0013] Furthermore, a trigger plate is fixedly installed on the top of the trapezoidal frame, a vent valve is provided on the first piston tube, a trigger switch is provided on the vent valve, and a connecting pipe is connected between the vent valve and the air box. When the first piston tube slides to the top of the trapezoidal frame, the trigger plate squeezes the trigger switch.

[0014] Furthermore, a fixed frame is fixedly installed on the base plate, and a reverse push frame is rotatably installed on the fixed frame. The trapezoidal frame slides and compresses the reverse push frame to rotate, and the top of the reverse push frame turns towards the second core plate.

[0015] Furthermore, a first push block is fixedly installed at the bottom end of the pusher frame, and a second push block is fixedly installed at the top end of the pusher frame, with a pressing plate movably installed on the second push block.

Secondly, auxiliary resistance components are set on the side of the core plates. When the first core plate deforms and tilts, the corresponding sliding frame is used to prevent it from tilting according to the direction of its compression. Furthermore, when the tilt angle of the first core plate is large, the resistance is immediately distributed to the second core plate, further improving the seismic resistance effect.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to embodiments.

[0023] Example 1: refer to Figure 1A two-stage metal yielding damper includes a base plate 1 and a multi-stage seismic resisting component, including a first core plate 2 installed on the base plate 1, a connecting plate 4 installed on the top of the first core plate 2, a second core plate 5 installed on the top of the connecting plate 4, first side plates 3 fixedly installed on both outer walls of the first core plate 2, second side plates 6 fixedly installed on both outer walls of the second core plate 5, and a top plate 7 fixedly installed on the top wall of the second core plate 5. The auxiliary resistance component includes two limiting frames 8 slidably mounted on the base plate 1. Each limiting frame 8 has a sliding frame 9 slidably mounted on it, with the top of the sliding frame 9 fully contacting the bottom of the connecting plate 4. A trapezoidal frame 12 is slidably mounted on the base plate 1. A lifting member is provided between the trapezoidal frame 12 and the sliding frame 9. When the connecting plate 4 presses the sliding frame 9 downwards, the lifting member resists the downward movement of the sliding frame 9. A sliding groove is provided on the limiting frame 8, and the sliding frame 9 is slidably mounted in the groove. A support plate 10 is fixedly mounted on the side of the sliding frame 9 near the connecting plate 4. The lifting member includes a slider 13 slidably mounted on the trapezoidal frame 12, and a first... A piston tube 14 is provided, with a first piston rod 15 movably inserted into its top. The first piston rod 15 is fixedly connected to the bottom wall of the sliding frame 9. A first return spring is provided in the first piston tube 14. The lifting component also includes a second piston tube 16 fixedly installed on the trapezoidal frame 12 near the first core plate 2. A second piston rod 17 is movably inserted into the second piston tube 16, and the second piston rod 17 is fixedly connected to the limiting frame 8. The second piston tube 16 and the first piston tube 14 are connected. Two baffles 11 are symmetrically fixedly installed on the top of the support plate 10, and the distance between the two baffles 11 is slightly larger than the width of the connecting plate 4. It is worth noting that the purpose of setting the baffles 11 is to allow the support plate 10 to be pressed when the first core plate 2 tilts back and forth.

[0024] The aforementioned yielding damper is composed of two core plates made of different materials, one above the other. Due to the different materials and cross-sections of the two core plates, their yield forces are also different. The first core plate 2 is made of LY100, and the second core plate 5 is made of LY225. The cross-section of the second core plate 5 is larger than that of the first core plate 2. Under wind-induced or minor earthquake conditions, the LY100 part first enters the yielding stage and forms the first-order yield force. As the displacement increases, the LY225 part also enters the yielding stage and forms the second-order yield force. Under wind-induced or minor earthquake conditions, the first-order yielding mainly consumes energy. Under major earthquake conditions, the first-order and second-order parts consume energy simultaneously, which is more effective in consuming energy.

[0025] like Figure 4As shown, during minor vibrations, the energy is primarily offset by the deformation generated by the first core plate 2. Support plates 10 are installed on both sides of the first core plate 2. The connecting plate 4 between the first core plate 2 and the second core plate 5 rests on the support plates 10. Depending on the direction of the first core plate 2's skewed deformation, different support plates 10 will be compressed. When a support plate 10 is compressed, it will also push the corresponding limiting frame 8 to slide. During this sliding process, the support plate 10 slides along the trapezoidal frame 12. On one hand, the first piston tube 14 slides upwards along the trapezoidal frame 12, thereby lifting the sliding frame 9 and the support plate 10 to resist deformation. On the other hand, the limiting frame 8 will also compress the second piston rod 17, forcing the air in the second piston tube 16 into the first piston tube 14, further raising the height of the first piston rod 15 and further enhancing the resistance effect.

[0026] Example 2: refer to Figure 3 An installation plate is fixedly installed on the inner wall of the limiting frame 8. A third piston tube 18 is fixedly installed on the installation plate. A third piston rod 19 is movably inserted into the top of the third piston tube 18. An auxiliary plate 20 is fixedly installed on the top of the third piston rod 19. The auxiliary plate 20, the third piston tube 18 and the first piston tube 14 are connected. An air box 21 is fixedly installed on the installation plate. A fourth piston rod 22 is movably inserted into the top of the air box 21. A push plate 23 is elastically connected to the top of the fourth piston rod 22. The push plate 23 is slidably connected to the side wall of the limiting frame 8. The limiting frame 8 has an inclined groove, and the push plate 23 is slidably installed in the inclined groove. When the push plate 23 moves upward, it moves closer to the second core plate 5 along the inclined groove. The top of the trapezoidal frame 12 is fixedly installed with a trigger plate 30. The first piston tube 14 is equipped with a vent valve 24, which is equipped with a trigger switch. A connecting pipe connects the vent valve 24 and the air box 21. When the first piston tube 14 slides to the top of the trapezoidal frame 12, the trigger plate 30 presses the trigger switch. The base plate 1 is fixedly installed with a fixing frame 25, and a reverse push frame 26 is rotatably installed on the fixing frame 25. The trapezoidal frame 12 slides and presses the reverse push frame 26 to rotate, and the top of the reverse push frame 26 turns towards the second core plate 5. The bottom of the reverse push frame 26 is fixedly installed with a first push block 27, and the top of the reverse push frame 26 is fixedly installed with a second push block 28. A pressing plate (not shown in the figure, but can be hinged to maximize the contact area with the second side plate 6 during pressing) is movably installed on the second push block 28. An elastic rod 29 connects the trapezoidal frame 12 and the fixed frame 25.

[0027] When the vibration is large, the deformation of the first core plate 2 is large, and the deformation of the second core plate 5 is also large. That is, the displacement caused by the compression of the limiting frame 8 is large, which causes the first piston tube 14 to slide to the top of the trapezoidal frame 12. The vent valve 24 on the first piston tube 14 is squeezed open, and the internal air enters the air box 21, causing the fourth piston rod 22 to move upward, pushing the push plate 23 upward. During the upward movement, the push plate 23 will also move towards the second core plate 5, pressing tightly on the second side plate 6, preventing the second core plate 5 from tilting and deforming, and improving the seismic resistance.

[0028] Secondly, when the first piston tube 14 slides to the top of the trapezoidal frame 12, the trapezoidal frame 12 will be compressed and slide towards the fixed frame 25, thereby compressing the first push block 27, such as... Figure 6 and Figure 7 As shown, the first push block 27 is squeezed, causing the counter-push frame 26 to rotate and turn towards the second core plate 5. The second push block 28 and the extrusion plate movably installed on its outside are used to squeeze the second side plate 6, further improving the auxiliary resistance effect on the second core plate 5.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
