Description

Technical Field

[0001] The invention relates to the technical field of energy-saving technology for high-rise steel structure green buildings, and in particular to a multiple energy-consuming structure capable of achieving dynamic deformation under strong earthquakes. Background Art

[0002] Earthquakes are one of the most destructive natural phenomena on Earth. The seismic waves released by earthquakes can cause serious damage to various buildings, infrastructure, and human life and property on the surface.

[0003] In the related art, most traditional building structures use rigid connections to ensure stability and strength under normal conditions. During an earthquake, this rigid connection will directly transmit the earthquake action to each component of the structure, causing the structure to bear greater stress.

[0004] At the same time, traditional building structures have limited deformation capacity and lack effective energy consumption mechanisms. The post-earthquake repair and reinforcement processes are complex, which affects the progress of post-disaster reconstruction and is costly. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present invention is to propose a multiple energy dissipation structure that can achieve dynamic deformation under strong earthquakes. The multiple energy dissipation structure can realize the mutual conversion of structural types and has multiple energy dissipation mechanisms. The multiple energy dissipation structure is basically not damaged after the earthquake, and is designed with a reset system, which greatly reduces the post-earthquake repair work and has a low maintenance cost.

[0006] The multiple energy dissipation structure proposed in the present invention that can realize dynamic deformation under strong earthquakes includes: Column; Main beam; A node plate, through which opposite ends of the main beam are respectively connected to the columns; A hydraulic mechanism, the hydraulic mechanism is arranged in parallel below the main beam; An anti-buckling energy dissipation support, one end of which is connected to the node plate, and the other end of which is connected to the hydraulic mechanism through the node plate. The anti-buckling energy dissipation support drives the hydraulic mechanism to operate through the node plate to absorb seismic energy.

[0007] The multiple energy dissipation structure provided by the embodiment of the present invention can play a key supporting role in the multiple energy dissipation structure by setting columns, and can significantly improve the overall stiffness and stability of the multiple energy dissipation structure. When the building is subjected to a large earthquake, the columns can effectively transfer the earthquake energy to the ground, thereby ensuring the safety of the building. In addition, the evenly distributed columns help to effectively distribute and transfer the earthquake energy according to the stiffness, avoid local stress concentration, and thus prevent the multiple energy dissipation structure from collapsing due to excessive horizontal deformation; by setting the main beam, a frame can be formed with the columns, thereby forming the first line of defense against earthquakes, thereby ensuring the safety of the multiple energy dissipation structure; by setting the node plate, the opposite ends of the main beam can be fixedly connected to the columns respectively through the node plate. Under the action of an earthquake, the node plate can improve the deformation resistance of the node between the main beam and the column, thereby ensuring the safety of the multiple energy dissipation structure; by setting the hydraulic mechanism, when the building is stationary or subjected to a small earthquake, the multiple energy dissipation structure can be connected through the hydraulic mechanism and the columns, main beams, etc. to maintain the static stability of the building; when the building is subjected to a large earthquake, the hydraulic mechanism can realize the dynamic conversion of the multiple energy-absorbing structure through action. The multiple energy-absorbing structure can be converted from the frame-central support structure before the earthquake to the frame-bottom eccentric support structure after the earthquake, and the upper frame-central support structure. Through the conversion of the structural system and the circulation of hydraulic oil in the hydraulic mechanism, the first energy consumption of the multiple energy-absorbing structure under a strong earthquake can be realized; the main beam of the frame-bottom eccentric support structure after the earthquake adds an energy-absorbing beam section, and the second energy consumption of the multiple energy-absorbing structure under a strong earthquake can be realized through the structural deformation of the energy-absorbing beam section and the setting of the first limiter, the second limiter and the third limiter; by setting the anti-buckling energy dissipation support, the lateral displacement stiffness of the multiple energy-absorbing structure can be increased and the ductility of the multiple energy-absorbing structure can be improved. At the same time, the anti-buckling energy dissipation support can give full play to the hysteretic energy dissipation capacity of the steel due to the characteristic that it will not buckle when under pressure, and the third energy consumption of the multiple energy-absorbing structure under a strong earthquake can be realized by using the expansion and contraction deformation of the flexible material. Through the tertiary energy dissipation of multiple energy-absorbing structures under strong earthquakes, most of the internal energy transferred to the building by the earthquake can be converted into mechanical energy to do work. The stability and safety of the building under strong earthquakes can be guaranteed through the dissipation of energy.

The second limiter is used to abut against the movable end of the hydraulic rod to limit the retreat of the hydraulic rod.

[0025] Reference below Figure 1-Figure 7 A multiple energy dissipation structure 10 according to an embodiment of the present invention is described, comprising: a column 100; a main beam 200; a node plate 300, wherein opposite ends of the main beam 200 are respectively connected to the column 100 through the node plate 300; a hydraulic mechanism 400, wherein the hydraulic mechanism 400 is arranged in parallel below the main beam 200; an anti-buckling energy dissipation support 500, wherein one end of the anti-buckling energy dissipation support 500 is connected to the node plate 300, and the other end of the anti-buckling energy dissipation support 500 is connected to the hydraulic mechanism 400 through the node plate 300, and the anti-buckling energy dissipation support 500 drives the hydraulic mechanism 400 to operate through the node plate 300 to absorb seismic energy.

[0026] Specifically, the column 100 can be constructed as a steel column with an H-shaped, rectangular or grooved cross-section, or a lattice column composed of multiple steel sections, which is not specifically limited in the embodiment of the present invention. The structural material of the column 100 can be a metal material, such as steel, which is a typical metal material with high strength, good plasticity and toughness, thereby significantly improving the load-bearing performance of the multiple energy dissipation structure 10.

[0027] The columns 100 can provide support for the multiple energy dissipation structure 10, thereby increasing the overall stiffness and strength of the multiple energy dissipation structure 10 and ensuring the stability of the multiple energy dissipation structure 10; when the building is subjected to a large earthquake, the columns 100 can transfer the earthquake energy to the ground, thereby ensuring the safety of the building; the evenly distributed columns 100 can evenly distribute the earthquake energy according to the stiffness, avoiding damage to the multiple energy dissipation structure 10 caused by excessive local stress.

[0028] There can be multiple columns 100, and users can select different numbers of columns 100 according to different buildings. The spacing between the columns 100 can be calculated and determined based on the earthquake energy, earthquake intensity, earthquake resistance level, number of floors, building plane and facade related information of the building, and users can adjust the different wheelbases between the columns 100 according to different buildings.

[0029] Furthermore, the cross-sectional shape of the main beam 200 can be constructed as an H-shaped, rectangular or groove-shaped, and can also be constructed as other irregular cross-sectional shapes, which is not specifically limited in the embodiments of the present invention. The user can select the main beam 200 with different cross-sectional shapes according to the seismic energy, span, material and function requirements of the multiple energy dissipation structure 10. The opposite ends of the main beam 200 can be fixedly connected to the column 100 by welding or bolting, so that the column 100 can provide support for the main beam 200. The number of main beams 200 can be determined according to the wheelbase of the column 100, and the user can select different numbers of main beams 200 according to different buildings.

[0030] The main beam 200 can transfer seismic energy with the column 100 , thereby ensuring that the seismic energy is distributed and transferred according to the stiffness, and further ensuring the safety of the multiple energy dissipation structure 10 .

[0031] Specifically, the node plate 300 can be constructed as an irregular plate-like structure with 45-degree cut angles at both ends of the top, or other irregular plate-like structures. The embodiment of the present invention does not specifically limit this, and the user can adjust the shape of the node plate 300 according to different application scenarios. The node plate 300 can be fixedly connected to the opposite ends of the main beam 200 by welding or threaded connection, and then fixedly connected to the column 100 by welding or threaded connection. In this way, the opposite ends of the main beam 200 can be fixedly connected to the column 100 by the node plate 300. Under the action of an earthquake, the node plate 300 can improve the deformation resistance of the connection point between the main beam 200 and the column 100, thereby ensuring the safety of the multiple energy dissipation structure 10.

[0032] The number of node plates 300 can be multiple, and the node plates 300 can be hinged with the buckling-resistant energy dissipation support 500 in the following embodiments by means of a pin connection. During the installation of the pin, the surface of the pin should be kept clean to ensure that the surface of the pin is free of impurities and rust, so as to facilitate the smooth installation of the pin; lubricating oil can also be applied to the surface of the pin, so as to reduce the friction between the pin and the mounting hole (not shown in the figure), thereby extending the service life of the pin. An elastic retaining ring anti-slip device (not shown in the figure) can also be installed between the pin and the mounting hole, so as to greatly improve the stability between the node plate 300 and the buckling-resistant energy dissipation support 500, thereby greatly improving the safety of the multiple energy dissipation structure 10.

[0033] One side of the node plate 300 hinged to the buckling-resisting energy dissipation support 500 can be fixedly connected to the column 100 by spot welding, and one end of the node plate 300 can abut against the main beam 200. It should be noted that the contact surface corner of the node plate 300 abutting against the bottom of the main beam 200 can be cut at a 45-degree angle, which can ensure that the hydraulic rod 430 in the following embodiments can slide without obstacles.

[0034] Stiffening ribs 310 may be provided around the node plate 300 hinged to the buckling-resistance energy dissipation support 500. The shape of the stiffening ribs 310 may be constructed as a straight steel plate. The stiffening ribs 310 may be installed around the node plate 300 by welding, thereby improving the local stability of the node plate 300 and preventing the node plate 300 from being unstable and damaged due to excessive local stress. The stiffening ribs 310 may also enhance the rigidity of the node plate 300 and simultaneously improve the service life of the node plate 300, thereby improving the service life of the multiple energy dissipation structure 10.

[0035] The hydraulic mechanism 400 can be arranged below the main beam 200 along the height direction of the multiple energy dissipation structure 10, and keep a certain distance from the main beam 200. Such arrangement can prevent the hydraulic mechanism 400 from colliding with the main beam 200 during operation, resulting in damage to the hydraulic mechanism 400 and the main beam 200. The height direction of the multiple energy dissipation structure 10 is Figure 4 The opposite ends of the hydraulic mechanism 400 can be fixedly connected to the column 100. With such an arrangement, when the building is stationary or subjected to relatively small earthquake energy, the multiple energy dissipation structure 10 can maintain the static stability of the building through the cooperation of the hydraulic mechanism 400, the column 100 and the main beam 200; when the building is subjected to relatively large earthquake energy, the hydraulic mechanism 400 can consume most of the kinetic energy transmitted between the column 100 and the main beam 200 through action, thereby ensuring the safety of the building.

[0036] One end of the buckling-resistance support 500 can be fixedly connected to the node plate 300 by welding, bolt connection or the like, and the other end of the buckling-resistance support 500 can be hinged to the diagonal node plate 300 by a connection method of a pin (not shown in the figure). In this way, the buckling-resistance support 500 can form a frame-central support structure with the column 100 and the main beam 200, thereby improving the overall stability and lateral stiffness of the multiple energy dissipation structure 10. The other end of the buckling-resistance support 500 can also be connected to the hydraulic mechanism 400 through the node plate 300, so that the buckling-resistance support 500 drives the hydraulic mechanism 400 to move through the node plate 300, and absorbs seismic energy through the translation of the buckling-resistance support 500 and the movement of the hydraulic mechanism 400, thereby ensuring the stability of the multiple energy dissipation structure 10.

[0037] The buckling-resistance brace 500 can be installed along the height direction of the multiple energy dissipation structure 10 at a place where the relative displacement between the bottom layers of the multiple energy dissipation structure 10 is large, so that the buckling-resistance brace 500 can offset the horizontal earthquake effect of the important parts of the multiple energy dissipation structure 10, thereby ensuring the safety of the multiple energy dissipation structure 10 and simultaneously reducing the manufacturing cost of the multiple energy dissipation structure 10. The structural material of the buckling-resistance brace 500 can be metal, for example, low-yield point Q235 steel and flexible material, so that the ductility of the multiple energy dissipation structure 10 can be significantly improved, and the manufacturing cost of the multiple energy dissipation structure 10 can be simultaneously reduced.

[0038] Please continue to see Figure 1 As shown, when the building is stationary or subjected to relatively small earthquake energy, the buckling-resistance energy dissipation support 500 can provide stable support for the multiple energy dissipation structure 10 to ensure the normal function of the multiple energy dissipation structure 10. At this time, the multiple energy dissipation structure 10 can be a frame-central support structure system.

[0039] Please continue to see Figure 2 and Figure 3As shown, when the building is subjected to a large earthquake, the hydraulic mechanism 400 can realize the dynamic conversion of the multiple energy-absorbing structure 10 through action. The multiple energy-absorbing structure 10 can be converted from the frame-central support structure before the earthquake to the frame-bottom eccentric support and upper frame-central support structure after the earthquake. Through the conversion of the structural system and the circulation of the hydraulic oil in the hydraulic mechanism 400, the first energy consumption of the multiple energy-absorbing structure 10 under a strong earthquake can be realized; the main beam 200 of the frame-bottom eccentric support structure after the earthquake is increased by the energy-absorbing beam section 210 in the following embodiment, and the energy-absorbing beam section 210 is increased by the energy-absorbing beam section 210 in the following embodiment. The structural deformation of the segment 210 and the arrangement of the first limiter 440, the second limiter 450 and the third limiter 460 in the following embodiments can realize the second energy dissipation of the multiple energy dissipation structure 10 under a strong earthquake; by arranging the anti-buckling energy dissipation support 500, the lateral stiffness of the multiple energy dissipation structure 10 can be increased and the ductility of the multiple energy dissipation structure 10 can be improved. At the same time, the anti-buckling energy dissipation support 500 can give full play to the hysteresis energy dissipation capacity of the steel material due to the characteristic of not buckling when under pressure, and the expansion and contraction deformation of the flexible material can realize the third energy dissipation of the multiple energy dissipation structure 10 under a strong earthquake. Through the three-time energy dissipation of the multiple energy dissipation structure 10 under a strong earthquake, most of the internal energy of the building transferred by the earthquake action can be converted into mechanical energy to do work, and the stability and safety of the building under a strong earthquake can be guaranteed by the dissipation of energy.

[0040] According to the multiple energy dissipation structure 10 provided by the embodiment of the present invention, the columns 100 can play a key supporting role in the multiple energy dissipation structure 10, and can significantly improve the overall stiffness and stability of the multiple energy dissipation structure 10. When the building is subjected to a large earthquake, the columns 100 can effectively transfer the earthquake energy to the ground, thereby ensuring the safety of the building. In addition, the evenly distributed columns 100 help to effectively distribute and transfer the earthquake energy according to the stiffness, avoid local stress concentration, and thus prevent the multiple energy dissipation structure 10 from collapsing due to excessive horizontal deformation; by setting the main beam 200, By forming a frame with the column 100, it can resist earthquake action, thereby ensuring the safety of the multiple energy dissipation structure 10; by setting the node plate 300, the opposite ends of the main beam 200 can be fixedly connected to the column 100 respectively through the node plate 300. Under the action of earthquake, the node plate 300 can improve the anti-deformation ability of the node between the main beam 200 and the column 100, thereby ensuring the safety of the multiple energy dissipation structure 10; by setting the hydraulic mechanism 400, when the building is stationary or subjected to a small earthquake, the multiple energy dissipation structure 10 can be connected to the column 100 through the hydraulic mechanism 400. , main beam 200, etc. to maintain the static stability of the building; when the building is subjected to a large earthquake, the hydraulic mechanism 400 can realize the dynamic conversion of the multiple energy-absorbing structure 10 through action, and the multiple energy-absorbing structure 10 can be converted from the frame-central support structure before the earthquake to the frame-bottom eccentric support and upper frame-central support structure after the earthquake. Through the conversion of the structural system and the circulation of hydraulic oil in the hydraulic mechanism 400, the first energy consumption of the multiple energy-absorbing structure 10 under a strong earthquake can be realized; the main beam 200 of the frame-bottom eccentric support structure after the earthquake has increased the energy-absorbing beam Segment 210, through the structural deformation of the energy absorbing beam segment 210 and the setting of the first limiter 440, the second limiter 450 and the third limiter 460, the second energy absorbing structure 10 can achieve the second energy absorbing under strong earthquakes; by setting the anti-buckling energy dissipation support 500, the lateral stiffness of the multiple energy absorbing structure 10 can be increased and the ductility of the multiple energy absorbing structure 10 can be improved. At the same time, the anti-buckling energy dissipation support 500 can give full play to the hysteresis energy dissipation capacity of steel due to the characteristic of not buckling when under pressure, and the third energy absorbing under strong earthquakes can be achieved by using the expansion and contraction deformation of the flexible material. Through the third energy dissipation of the multiple energy absorbing structure 10 under strong earthquakes, most of the internal energy transferred to the building by the earthquake action can be converted into mechanical energy to do work, and the stability and safety of the building under strong earthquakes can be guaranteed by the dissipation of energy.

[0041] Please continue to see Figure 4-Figure 6 As shown, according to one embodiment of the present invention, the multiple energy dissipation structure 10 further includes: a guide rail 600, which is arranged in parallel below the main beam 200, and the opposite ends of the guide rail 600 are respectively connected to the column 100, and the guide rail 600 is used to connect the hydraulic mechanism 400.

[0042] Specifically, the guide rail 600 can be arranged in parallel below the main beam 200 along the height direction of the multiple energy dissipation structure 10, and the opposite ends of the guide rail 600 can be fixedly connected to the column 100 by bolt connection, welding or other connection methods. In this way, the column 100 can provide support for the guide rail 600, thereby improving the structural stability of the multiple energy dissipation structure 10. The guide rail 600 can be connected to the hydraulic mechanism 400 and provide support for the hydraulic mechanism 400. The extension direction of the guide rail 600 can be parallel to the extension direction of the main beam 200. The extension direction of the guide rail 600 is Figure 4 Such arrangement allows some components of the hydraulic mechanism 400 to slide freely on the guide rail 600, thereby ensuring that the movement direction of the hydraulic mechanism 400 is consistent with the extension direction of the main beam 200, avoiding additional stress caused by directional deviation, and thus ensuring the stability of the multiple energy dissipation structure 10.

[0043] It should be noted that a certain distance should be maintained between the guide rail 600 and the main beam 200 when they are installed, so as to ensure that the hydraulic mechanism 400 has a certain activity space, thereby avoiding damage to the multiple energy-consuming structure 10 caused by the movement of the hydraulic mechanism 400.

[0044] Please continue to see Figure 4-Figure 7 As shown, according to another embodiment of the present invention, the hydraulic mechanism 400 includes: a hydraulic cylinder 410, which is fixedly connected to the guide rail 600; a piston 420, which is movably sleeved inside the hydraulic cylinder 410, and the piston 420 divides the interior of the hydraulic cylinder 410 into a first chamber 411 and a second chamber 412, and the first chamber 411 and the second chamber 412 are respectively filled with hydraulic oil; a hydraulic rod 430, a fixed end 431 of the hydraulic rod 430 is fixedly connected to the node plate 300, and a movable end 432 of the hydraulic rod 430 passes through the opposite ends of the hydraulic cylinder 410 and the piston 420 in sequence, and the hydraulic rod 430 is fixedly connected to the piston 420, and the node plate 300 drives the piston 420 to move in the hydraulic cylinder 410 through the hydraulic rod 430.

[0045] Specifically, the hydraulic cylinder 410 can be fixedly connected to the guide rail 600 by bolt connection or welding, so as to ensure that the hydraulic cylinder 410 will not be relatively displaced during operation, thereby ensuring the safety of the multiple energy dissipation structure 10. During the installation of the hydraulic cylinder 410, it should be ensured that the central axis of the hydraulic cylinder 410 is parallel to the extension direction of the guide rail 600. For example, a level gauge or other tool can be used for measurement and adjustment, so as to ensure that the hydraulic rod 430 in the following embodiments is smooth and unobstructed during the extension process, thereby avoiding the hydraulic rod 430 from colliding with other parts during the extension process and causing damage. The interior of the hydraulic cylinder 410 can be filled with hydraulic oil. As a key medium for energy transmission and dissipation, the hydraulic oil can effectively absorb shock and vibration, reduce the impact force on the hydraulic cylinder 410, and ensure the smooth operation of the hydraulic cylinder 410.

[0046] Furthermore, the piston 420 may be constructed as an irregular shape with a hollow interior and a plurality of uniform through holes (not shown in the figure), and the cross-sectional shape of the piston 420 should be consistent with the cross-sectional shape of the interior of the hydraulic cylinder 410. Such a configuration facilitates the piston 420 to be tightly sleeved inside the hydraulic cylinder 410. The piston 420 may divide the interior of the hydraulic cylinder 410 into a first chamber 411 and a second chamber 412, both of which are closed environments, and the first chamber 411 and the second chamber 412 may be filled with hydraulic oil, respectively.

[0047] Under a strong earthquake, the hydraulic mechanism 400 starts to operate, and the hydraulic oil can flow from the first chamber 411 to the second chamber 412, or from the second chamber 412 to the first chamber 411, through the uniform through holes on the piston 420. This can effectively convert part of the kinetic energy generated by the vibration of the multiple energy-absorbing structure 10 into heat energy, thereby reducing the vibration energy transmitted to the main body of the building by the earthquake.

[0048] Furthermore, the fixed end 431 of the hydraulic rod 430 can be fixedly connected to the stiffening rib 310 of the node plate 300 by welding, so that the hydraulic rod 430 can drive the node plate 300 to move when moving. The node plate 300 and the buckling-resistance energy dissipation support 500 are connected by a pin shaft. With such an arrangement, when the multiple energy dissipation structure 10 vibrates, the hydraulic rod 430 can drive the buckling-resistance energy dissipation support 500 to translate within a certain range to dissipate energy, reduce most of the energy brought by the vibration, and thus ensure the stability of the building.

[0049] The movable end 432 of the hydraulic rod 430 can be set as a boss structure, and the movable end 432 of the hydraulic rod 430 can penetrate the opposite ends of the hydraulic cylinder 410 and the piston 420 inside the hydraulic cylinder 410 by a sleeve connection, so that the hydraulic rod 430 can reciprocate relative to the hydraulic cylinder 410. The hydraulic rod 430 can be fixedly connected with the piston 420 by a coaxial sleeve connection, and the fixed end 431 of the hydraulic rod 430 is fixedly connected with the node plate 300. In this way, when the hydraulic rod 430 and the node plate 300 are translated together, the node plate 300 can drive the piston 420 through the hydraulic rod 430, so that the piston 420 is translated in the same direction inside the hydraulic cylinder 410, thereby changing the volume inside the first chamber 411 and the second chamber 412 of the hydraulic cylinder 410. When the hydraulic rod 430 translates in the hydraulic cylinder 410, the hydraulic oil is compressed to flow between the first chamber 411 and the second chamber 412 so that the hydraulic oil can effectively absorb most of the energy generated by the earthquake in the building, thereby ensuring the stability of the building.

[0050] During the installation of the hydraulic rod 430, by evenly applying a proper amount of special lubricant on the surface of the hydraulic rod 430, the friction and wear of the hydraulic rod 430 when moving in the hydraulic cylinder 410 can be reduced, and at the same time, it helps to improve the sealing inside the hydraulic cylinder 410; during the installation of the hydraulic rod 430 and the hydraulic cylinder 410, it should be ensured that the axis of the hydraulic rod 430 coincides with the axis of the hydraulic cylinder 410, so as to avoid the hydraulic rod 430 from tilting or colliding, causing damage to the hydraulic mechanism 400 or bending of the hydraulic rod 430, thereby ensuring the safety and structural stability of the hydraulic mechanism 400.

[0051] Please continue to see Figure 4-Figure 7 As shown, according to another embodiment of the present invention, the hydraulic mechanism 400 also includes: a first limiter 440, the first limiter 440 is connected to the guide rail 600, and the first limiter 440 is spaced apart on the side of the hydraulic cylinder 410 away from the node plate 300, and the first limiter 440 is used to connect with the movable end 432 of the hydraulic rod 430 to limit the initial position of the hydraulic rod 430.

[0052] Specifically, the first stopper 440 can be constructed as a rectangular stopper plate, and the number of the first stopper 440 can be two pairs. The first stopper 440 can be installed at intervals on the upper and lower inner sides of the guide rail 600 by welding, riveting or bolting, and a symmetrical layout is adopted. The spacing distance between the first stoppers 440 can be adjusted accordingly according to different hydraulic rods 430. In this way, the practicality of the hydraulic mechanism 400 can be effectively improved. The first stopper 440 can be arranged at intervals on the side of the hydraulic cylinder 410 away from the node plate 300, which is convenient for limiting the initial position of the hydraulic mechanism 400. The first stopper 440 can be fixedly connected to the movable end 432 of the hydraulic rod 430 by threaded connection. In this way, the first stopper 440 can limit the forward movement of the hydraulic rod 430; the first stopper 440 can also be installed at intervals at the step of the movable end 432 of the hydraulic rod 430 by bolting. In this way, the first stopper 440 can limit the movement of the hydraulic rod 430.

[0053] By providing two pairs of first stoppers 440, when the building is in normal use or in a minor earthquake, the first stoppers 440 can limit the initial position of the hydraulic rod 430, thereby ensuring the static stability of the entire multiple energy dissipation structure 10. It should be noted that the spacing distance of the first stoppers 440 can be adjusted according to the thickness of the boss of the movable end 432 of the hydraulic rod 430, thereby improving the flexibility of the hydraulic mechanism 400.

[0054] The initial position of the hydraulic mechanism 400 is the initial fixed position of the hydraulic rod 430 when the multiple energy dissipation structure 10 is installed.

[0055] Please continue to see Figure 4-Figure 7 As shown, according to an optional embodiment of the present invention, the hydraulic mechanism 400 also includes: a second limiter 450, the second limiter 450 is connected to the guide rail 600, and the second limiter 450 is spaced apart on the side of the first limiter 440 away from the hydraulic cylinder 410, and the second limiter 450 is used to abut against the movable end 432 of the hydraulic rod 430 to limit the hydraulic rod 430 from retreating.

[0056] Specifically, the second stopper 450 may include a spring 451 and a trapezoidal stopper block 452, one end of the spring 451 may be fixedly connected to the right angle surface of the trapezoidal stopper block 452 by welding, and the other end of the spring 451 may be fixedly connected to the guide rail 600 by welding, so that the guide rail 600 can provide support for the second stopper 450. The second stopper 450 may also be arranged at intervals on a side of the first stopper 440 away from the hydraulic cylinder 410, and the trapezoidal stopper block 452 may be used to abut against the movable end 432 of the hydraulic rod 430, so as to limit the hydraulic rod 430 from retreating.

[0057] The installation position of the second limiter 450 can be determined according to the movable distance of the hydraulic cylinder 410 and the movable distance of the anti-buckling energy dissipation support 500. The user can select a suitable installation position of the second limiter 450 according to different application scenarios.

[0058] When the building is subjected to a large earthquake energy, by setting the second stopper 450, the hydraulic rod 430 breaks through the first stopper 440 and moves toward the second stopper 450. When the movable end 432 of the hydraulic rod 430 reaches the installation position of the second stopper 450, the hydraulic rod 430 can abut against the trapezoidal stopper 452. As the movable end 432 of the hydraulic rod 430 moves, the trapezoidal stopper 452 drives the spring 451 to squeeze and contract. When the movable end 432 of the hydraulic cylinder 410 passes through the second stopper 450, the spring 451 can drive the trapezoidal stopper 452 to return to its original state. At this time, the trapezoidal stopper 452 can limit the retreat of the movable end 432 of the hydraulic rod 430. The second stopper 450 can convert part of the kinetic energy generated by the building during a strong earthquake into elastic potential energy, thereby ensuring the stability of the building.

[0059] Please continue to see Figure 4-Figure 7 As shown, according to a further embodiment of the present invention, the hydraulic mechanism 400 also includes: a third limiter 460, which is connected to the guide rail 600, and the third limiter 460 is spaced apart on the side of the second limiter 450 away from the first limiter 440, and the third limiter 460 is used to abut against the movable end 432 of the hydraulic rod 430 to limit the terminal position of the hydraulic rod 430.

[0060] Specifically, the third stopper 460 can be constructed as a rectangular stopper block cast by concrete, and the third stopper 460 can be fixedly connected to the guide rail 600 by bolt connection. The third stopper 460 can be arranged on the side of the second stopper 450 away from the first stopper 440. In this way, the end position of the hydraulic rod 430 can be determined. The other end of the third stopper 460 can be used to abut against the movable end 432 of the hydraulic rod 430. When a strong earthquake occurs, the hydraulic rod 430 passes through the second stopper 450 to reach the third stopper 460, and the movable end 432 of the hydraulic rod 430 can abut against the third stopper 460, so that the end position of the hydraulic rod 430 can be defined.

[0061] The thickness of the third limiter 460 can be calculated and determined according to the movable distance of the hydraulic rod 430 , and the third limiter 460 can be set at the end of the stroke of the hydraulic rod 430 , thereby preventing the hydraulic rod 430 from being excessively displaced and causing damage to the multiple energy dissipation structure 10 .

[0062] The end position of the hydraulic rod 430 may be a stroke end position of the hydraulic rod 430 .

[0063] Please continue to see Figure 2 and Figure 5 As shown, in one embodiment of the present invention, when the building is under a strong left earthquake, the movable end 432 of the hydraulic rod 430 can break through the first limiter 440 and move to the left through the second limiter 450, reaching the third limiter 460 and abutting against the third limiter 460; at this time, the fixed end 431 of the hydraulic rod 430 can drive the node plate 300 to move to the left together, and the anti-buckling energy dissipation support 500 is hinged to the node plate 300. Under a strong earthquake, the anti-buckling energy dissipation support 500 can rotate counterclockwise and move to the left together with the node plate 300 until the hydraulic rod 430 abuts against the third limiter 460.

[0064] Please continue to see Figure 3 and Figure 6 As shown, in another embodiment of the present invention, when the building is under a strong right earthquake, the movable end 432 of the hydraulic rod 430 can break through the first limiter 440 and move to the right through the second limiter 450, reaching the third limiter 460 and abutting against the third limiter 460; at this time, the fixed end 431 of the hydraulic rod 430 can drive the node plate 300 to move to the right together, and the anti-buckling energy dissipation support 500 is hinged to the node plate 300. Under the action of earthquake energy, the anti-buckling energy dissipation support 500 can rotate clockwise and move to the right together with the node plate 300 until the hydraulic rod 430 abuts against the third limiter 460.

[0065] By setting the hydraulic mechanism 400, a multiple energy dissipation system can be formed, and under different earthquake energies, the multiple energy dissipation systems can play a role according to their respective advantages. Under normal / small earthquakes, the multiple energy dissipation structure 10 can rely on the anti-lateral displacement stiffness provided by the buckling-resistance energy dissipation support 500, and coordinate the force with the hydraulic mechanism 400 to maintain the stability of the building; as the earthquake energy level further increases, the multiple energy dissipation structure 10 can consume most of the energy generated by the earthquake through the flow of hydraulic oil inside the hydraulic cylinder 410 and the conversion of the structural system to achieve the first energy dissipation of the multiple energy dissipation structure 10, and then through the setting of the first limiter 440, the second limiter 450 and the third limiter 460 and the deformation of the energy dissipation beam section 210, the second energy dissipation of the multiple energy dissipation structure 10 is achieved, and finally through the flexibility of the buckling-resistance energy dissipation support 500 material itself, the third energy dissipation of the multiple energy dissipation structure 10 is achieved, so that a multiple energy dissipation system can be formed, and then the safety of the building can be effectively protected under strong earthquakes.

[0066] Please continue to see Figure 4-Figure 7As shown, in an optional embodiment of the present invention, the hydraulic mechanism 400 also includes: an oil delivery component 470, which is connected to the first chamber 411 and the second chamber 412 respectively, and the oil delivery component 470 is used to deliver hydraulic oil from the first chamber 411 to the second chamber 412 or from the second chamber 412 to the first chamber 411.

[0067] Specifically, the oil delivery assembly 470 can be connected and communicated with the first chamber 411 and the second chamber 412 of the hydraulic cylinder 410, respectively, so as to facilitate the transmission of the hydraulic oil in the hydraulic mechanism 400. In one embodiment of the present invention, the oil delivery assembly 470 can deliver the hydraulic oil in the hydraulic cylinder 410 from the first chamber 411 to the second chamber 412; in another embodiment of the present invention, the oil delivery assembly 470 can deliver the hydraulic oil in the hydraulic cylinder 410 from the second chamber 412 to the first chamber 411.

[0068] Please continue to see Figure 7 As shown, in some examples of the present invention, the oil delivery component 470 includes: an oil pump 471; an oil pipe 472, the oil pipe 472 is connected to the inlet and outlet of the oil pump 471; and a valve 473, the oil pipe 472 is connected to the first chamber 411 and the second chamber 412 respectively through the valve 473.

[0069] Specifically, the oil pump 471 can be fixedly installed in the oil delivery circuit by bolt connection. During the installation process, attention should be paid to the horizontality and verticality of the oil pump 471 to avoid vibration and noise caused by improper installation of the oil pump 471.

[0070] There may be multiple oil pipes 472, and the oil pipes 472 may connect the oil pump 471 and the first chamber 411 and the second chamber 412 of the hydraulic cylinder 410, so that the first chamber 411 and the second chamber 412 may form a closed-loop oil circuit. During installation, pipe joints (not shown in the figure) may be installed at both ends of the oil pipe 472, and one end of the oil pipe 472 with the pipe joints installed may be connected to the oil outlet of the oil pump 471, and the other end may be connected to the oil inlet of the hydraulic cylinder 410. Such an arrangement may effectively improve the sealing of the oil circuit, thereby improving the reliability of the oil delivery assembly 470.

[0071] Valve 473 can be constructed as a hydraulic valve 473, and valve 473 can be installed at both ends of the oil pipe 472. With this arrangement, hydraulic valve 473 can accurately control the flow, pressure and direction of the hydraulic mechanism 400, thereby improving the safety and reliability of the oil circuit, while reducing the maintenance cost and failure rate of the oil delivery component 470.

[0072] Under normal conditions, valve 473 is in a closed state, and the hydraulic oil in the first chamber 411 and the second chamber 412 will not be transmitted to each other through the oil circuit; when the strong earthquake is over, the user can open valve 473, and the oil pump 471 starts to work. In one embodiment of the present invention, the oil pump 471 can transport the hydraulic oil in the first chamber 411 to the second chamber 412 through the oil pipe 472, the hydraulic rod 430 is reset, and the valve 473 is closed; in another embodiment of the present invention, the oil pump 471 can transport the hydraulic oil in the second chamber 412 to the first chamber 411 through the oil pipe 472, the hydraulic rod 430 is reset, and the valve 473 is closed. By providing the oil delivery assembly 470, the hydraulic rod 430 can be quickly restored to the pre-earthquake state, thereby significantly reducing the maintenance time and cost of the multiple energy-consuming structure 10 after a strong earthquake.

[0073] In addition, in the post-earthquake repair work, compared with the traditional energy dissipation mechanism, the multiple energy dissipation structure 10 has a three-stage energy dissipation design, and the anti-buckling energy dissipation support 500 after the earthquake is basically undamaged and can continue to be put into use, thereby greatly saving the maintenance cost of the multiple energy dissipation structure 10 and significantly shortening the post-earthquake repair progress.

[0074] Please continue to see Figure 4-Figure 6 As shown, in some examples of the present invention, the main beam 200 includes: an energy-absorbing beam section 210 and a non-energy-absorbing beam section 220 that are interconnected, the energy-absorbing beam section 210 has a plurality of transverse stiffening ribs 230 that are spaced apart, and the transverse stiffening ribs 230 are used to increase the stiffness of the energy-absorbing beam section 210.

[0075] Specifically, when the hydraulic rod 430 abuts against the third stopper 460, the buckling-resistance energy dissipation support 500 rotates and translates a certain distance on the main beam 200. The beam section of the main beam 200 within the translation range of the buckling-resistance energy dissipation support 500 is the energy-absorbing beam section 210, and the beam section of the main beam 200 outside the translation range of the buckling-resistance energy dissipation support 500 is the non-energy-absorbing beam section 220. The energy-absorbing beam section 210 can absorb and consume the energy of the building caused by the earthquake through its own deformation, thereby reducing the damage of the multiple energy-absorbing structure 10 to ensure the safety of the building. The length of the energy-absorbing beam section 210 can be determined by calculation. It should be noted that the energy-absorbing beam section 210 should not be greater than 1.6Mlp / Vl as specified in the specification.

[0076] Transverse stiffening ribs 230 can be evenly arranged within the length range of the energy-absorbing beam section 210. The transverse stiffening ribs 230 can be constructed as a straight steel plate. The transverse stiffening ribs 230 can be connected to the upper and lower flanges (not shown in the figure) and the web (not shown in the figure) of the main beam 200 by welding. Such an arrangement can ensure the rigidity and local stability of the energy-absorbing beam section 210, thereby ensuring that the main beam 200 can effectively and continuously dissipate energy without instability. The spacing of the transverse stiffening ribs 230 can be determined according to calculations, and users can select different spacings of the transverse stiffening ribs 230 according to different application scenarios.

[0077] Please continue to see Figure 1-Figure 3 As shown, in some examples of the present invention, the multiple energy dissipation structure 10 further includes a straight-line central support 700 , and opposite ends of the straight-line central support 700 are respectively fixedly connected to the node plate 300 .

[0078] Specifically, one end of the straight-line center support 700 can be fixedly connected to the node plate 300 by welding, and the other end of the straight-line center support 700 can also be fixedly connected to the diagonal node plate 300 by welding. In this way, the straight-line center support 700 can provide stable support for the column 100. It should be noted that the installation position of the straight-line center support 700 should be located at the third floor or above at the bottom of the multiple energy dissipation structure 10. In this way, during a strong earthquake, the columns 100, main beams 200 and anti-buckling energy dissipation supports 500 on the bottom two floors can be converted from a frame-center support structure to a frame-bottom eccentric support structure, while the upper columns 100, main beams 200 and the straight-line center support 700 can maintain the frame-center support structure, so that the multiple energy dissipation structure 10 can achieve multiple energy dissipation and simultaneously reduce the manufacturing cost of the multiple energy dissipation structure 10.

[0079] Other components of the multiple energy dissipation structure 10 capable of achieving dynamic deformation under strong earthquakes according to the embodiment of the present invention, such as welding, pipe joints, oil circuits, etc., and operations are well known to ordinary technicians in the field and will not be described in detail here.
