Description

Technical Field

[0001] This invention relates to the field of steel-wood hybrid structure node components, specifically to an energy-dissipating and vibration-damping node component and assembly method for a steel-wood hybrid structure. Background Technology

[0002] Steel-wood hybrid structures are widely used in the construction field. They combine the high strength of steel with the environmental protection and aesthetics of wood, resulting in good comprehensive performance. However, in steel-wood hybrid structures, the joints, as key parts connecting different components, are subject to complex stress conditions and can easily become weak points in the structure under external loads such as earthquakes and strong winds.

[0003] To address the aforementioned deficiencies, existing technology 1 (Chinese patent CN214036652U, published on 2021-08-24) provides a vibration-damping connection node, comprising a fixed plate. A slide rod and a main rod are arranged on one side of the fixed plate. A first spring and a damping pad are arranged on the outer diameter of the slide rod. A transmission rod is arranged on one side of the slide rod, and a piston rod with a piston is arranged at one end of the transmission rod. The piston is slidably connected to a vibration-damping cylinder. A damping hole is formed on the piston. The first spring and the damping pad provide initial vibration damping, and the damping pad also has a noise reduction effect. Vibration is transmitted through the slide rod and transmission rod, causing the piston to move. Hydraulic oil in the vibration-damping cylinder passes through the damping hole on the piston, generating damping to reduce vibration, thereby reducing the impact of vibration on the connection node. By setting a transmission rod on the slide rod and a partition plate at the center of the vibration-damping cylinder, the transmitted vibration is divided into two parts for damping, reducing the pressure on a single vibration-damping system and improving the vibration damping effect of the connection node.

[0004] There is also a prior art (Chinese patent CN115450338B, published on 2024-06-11) of a shock-absorbing steel structure node component, which relates to the field of building steel processing technology. It includes: several parallel steel frames, each with a base at its bottom; an assembly component detachably mounted on the surface of each steel frame; and a frame assembly mounted at the top of each steel frame in a deflecting manner. The frame assembly and the assembly component are connected by a shock-absorbing mechanism, and a structural steel frame is erected above the frame assembly. The shock-absorbing mechanism includes interlocking cylindrical cylinders, and two sets of cylindrical cylinders are connected by elastic elements. By designing the shock-absorbing mechanism on the corresponding steel frame, if shear force is generated at the node position of the component, the lever principle can be used to support and dampen the structural steel frame, preventing the entire upper frame from easily breaking due to excessive force. This component can protect the node and has high applicability.

[0005] While existing technologies have achieved vibration reduction to some extent, they still have shortcomings in adapting to the characteristics of steel-wood hybrid structures and in multi-dimensional synergistic improvement of vibration reduction performance. For example, existing technologies mainly rely on a combination of springs, damping pads and hydraulic damping, which has a relatively complex structure and does not adequately consider the different deformation characteristics of steel and wood, which may lead to stress concentration or uneven vibration reduction at joints.

[0006] Therefore, we propose an energy-dissipating and vibration-damping node component and assembly method for a steel-wood hybrid structure to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an energy-dissipating and vibration-damping node component and assembly method for a steel-wood hybrid structure, in order to solve the problems mentioned in the background art, which currently mainly rely on the combination of springs, damping pads and hydraulic damping, which has a relatively complex structure and does not adequately consider the different deformation characteristics of steel and wood, which may lead to stress concentration or uneven vibration reduction effect at the node.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an energy-dissipating and vibration-damping node component and assembly method of a steel-wood hybrid structure, comprising a positioning shell, wherein fixed plates are fixedly connected to both the left and right sides of the positioning shell, and auxiliary rings are provided on the upper and lower sides of the positioning shell. The fixed plates are provided with mounting holes for fixed connection with external structures. The material is high-strength steel to ensure the stability of the connection between the node component and the main structure. A buffer mechanism is provided between the auxiliary rings and the positioning shell. The buffer mechanism achieves initial buffering of external force impact through the mutual cooperation of the first hinge and the second hinge included therein. An auxiliary mechanism is provided inside the positioning shell and inside the buffer mechanism. The auxiliary mechanism drives the airbag to deform through the buffering force to further buffer the main structure.

[0009] Preferably, the buffer mechanism includes a second connecting shaft, which is rotatably connected to the fixed plate, and the outer end of the second connecting shaft is fixedly connected to the second hinge member. The outer side of the second hinge member is hinged to the first connecting shaft, and the first connecting shaft is fixedly connected to the first hinge member. The other end of the first hinge member is fixedly connected to the auxiliary ring.

[0010] Preferably, a first torsion spring is fixedly connected to the outer side of the first connecting shaft and the outer side of the second hinge, and a second torsion spring is fixedly connected between the inner side of the second hinge and the fixing plate. The first torsion spring and the second torsion spring cooperate with each other to play a role in resetting and buffering the rotation of the first connecting shaft and the second connecting shaft.

[0011] Preferably, the auxiliary mechanism includes an abutment airbag, which is fixedly connected to the inner side of the positioning shell, and the outer side of the abutment airbag is in contact with the outer wall of the main structure. In a stable state, the inner side of the abutment airbag does not contact the positioning shell, and a connecting pipe is connected through the side of the abutment airbag.

[0012] Preferably, a fixing box is fixedly connected to the fixing plate, and the side of the fixing box is connected to the other end of the connecting pipe. An air supply plate is slidably connected inside the fixing box, and a connecting rod is fixedly connected to the lower end of the air supply plate. The connecting rod is slidably connected to the lower side of the fixing box, and a pull plate is fixedly connected to the lower end of the connecting rod. A return spring is fixedly connected between the lower surface of the air supply plate and the interior of the fixing box.

[0013] Preferably, an auxiliary shaft is fixedly connected to the outer end of the first connecting shaft, and a traction cable is fixedly connected to the outer side of the auxiliary shaft. The other end of the traction cable is fixedly connected to the bottom of the pull plate, and the air supply plate is located above the fixed box in a stable state.

[0014] Preferably, the positioning shell has an internal movable groove, and the front and rear sides of the positioning shell are fixedly connected to the abutment plates. The left and right ends of the abutment plates are slidably connected to the inside of the movable groove, and the middle part of the abutment plate is attached to the outer side of the main structure. At the same time, the edge of the abutment plate is set with an arc-shaped structure.

[0015] Preferably, auxiliary plates are fixedly connected to both sides of the inner side of the airbag, and an abutment rod is slidably connected inside the movable groove. The abutment rod has an arc-shaped side, one end of which is located between the auxiliary plate and the positioning shell, and the other end of which is positioned towards the arc-shaped end of the abutment plate.

[0016] An assembly method for an energy-dissipating and vibration-damping node component in a steel-wood hybrid structure includes the following steps:

[0017] S1: Install the positioning shell and auxiliary ring at the preset position of the main structure, ensuring that the central axis of the positioning shell is basically coincident with the central axis of the main structure, and the auxiliary ring is located on the upper and lower sides of the positioning shell and initially fits against the outer wall of the main structure.

[0018] S2: Use high-strength bolts to fix the fixing plate to the external steel-wood composite main frame through the mounting holes on the fixing plate. When tightening the bolts, ensure that the fixing plates on both sides are evenly stressed to ensure that the positioning shell is installed firmly without any looseness. Check the connection of each component of the buffer mechanism. Manually push the auxiliary ring and observe whether the rotation of the first hinge and the second hinge around the first connecting shaft and the second connecting shaft is smooth. At the same time, confirm that the first torsion spring and the second torsion spring can provide stable elastic restoring force during rotation.

[0019] S3: Debug the auxiliary mechanism. First, check whether the contact airbag is intact and whether there is any air leakage. Then, connect both ends of the connecting pipe to the contact airbag and the fixed box respectively to ensure that the connection is well sealed. Next, observe whether the air supply plate is above the fixed box in a stable state, whether the traction cable is in a taut state but not overstretched, and whether the return spring is in a natural extension and contraction state. Observe whether the buffer mechanism can achieve initial buffering through the cooperation of the first hinge and the second hinge. At the same time, observe whether the auxiliary mechanism can drive the contact airbag to deform and further buffer the main structure to ensure that the energy dissipation and shock absorption function of the entire node component is normal.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] When the main structure is subjected to external impact or vibration, the auxiliary ring first contacts the impact source and generates displacement, which drives the first hinge fixedly connected to it to move. The first hinge drives the second hinge to rotate around the second connecting shaft through the first connecting shaft. At this time, the first torsion spring and the second torsion spring undergo elastic deformation due to the relative rotation of the first connecting shaft and the second connecting shaft, and use their elastic potential energy to initially buffer the impact of the external force and consume part of the impact energy.

[0022] When the first connecting shaft rotates and drives the upper end of the second hinge to move up and down, the auxiliary shaft fixedly connected to its outer end moves synchronously, thereby generating a pulling force on the pull plate through the traction cable. After the pull plate is subjected to force, it drives the air supply plate to slide downward in the fixed box through the connecting rod. The gas inside the fixed box is compressed and is pressed into the contact airbag through the connecting pipe, causing the contact airbag to expand and deform. The expanded contact airbag will generate a greater wrapping force and squeezing force on the outer wall of the main structure. The compressibility of the gas and the elasticity of the airbag are used to further absorb and buffer the vibration energy.

[0023] When the airbag inflates, the auxiliary plates on both sides inside the airbag expand to the sides, pushing the abutment rod located between the auxiliary plates and the positioning shell. The left and right ends of the abutment plate are slidably connected in the movable groove, and the middle part is attached to the outer side of the main structure. Under the pushing force of the abutment rod, the abutment plate will move further towards the main structure, enhancing the clamping and stabilizing effect on the main structure, effectively limiting the lateral displacement of the main structure under impact, thus forming a synergistic effect with the airbag buffer of the buffer mechanism and auxiliary mechanism, significantly improving the overall energy dissipation and shock absorption effect of the node components.

[0024] When the external impact or vibration weakens or disappears, the first and second torsion springs release their elastic potential energy, causing the first and second connecting shafts to rotate in opposite directions, thus resetting the first and second hinges. The auxiliary shaft then returns to its initial position, the tension of the traction cable against the pull plate disappears, and the return spring pushes the air supply plate to move upward and reset. The initial air pressure is restored in the fixed box, the gas in the contact airbag flows back to the fixed box, the contact airbag contracts, and the contact rod and contact plate also return to a stable state after their respective forces disappear. The entire node assembly returns to its initial stable position, preparing for the next possible impact. Attached Figure Description

[0035] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: As Figure 1 , Figure 2 , Figure 6 and Figure 7 The technical solution shown in the invention provides the following technical solution: a steel-wood hybrid structure energy-dissipating and vibration-damping node component and assembly method, which discloses a positioning shell 1, with fixing plates 3 fixedly connected to both the left and right sides of the positioning shell 1, and auxiliary rings 2 provided on the upper and lower sides of the positioning shell 1. The fixing plates 3 have mounting holes for fixed connection with external structures. The material is high-strength steel to ensure the stability of the connection between the node component and the main structure. A buffer mechanism is provided between the auxiliary rings 2 and the positioning shell 1. The buffer mechanism achieves initial buffering of external force impact through the mutual cooperation of the first hinge 4 and the second hinge 5 included therein. The buffer mechanism includes a second... The connecting shaft 22 is rotatably connected to the fixed plate 3, and the outer end of the second connecting shaft 22 is fixedly connected to the second hinge 5. The outer side of the second hinge 5 is hinged to the first connecting shaft 21, and the first connecting shaft 21 is fixedly connected to the first hinge 4. The other end of the first hinge 4 is fixedly connected to the auxiliary ring 2. The outer side of the first connecting shaft 21 and the outer side of the second hinge 5 are fixedly connected to the first torsion spring 6. The inner side of the second hinge 5 and the fixed plate 3 are fixedly connected to the second torsion spring 14. The first torsion spring 6 and the second torsion spring 14 cooperate with each other to play a role in resetting and buffering the rotation of the first connecting shaft 21 and the second connecting shaft 22.

[0037] When the main structure is subjected to external impact or vibration, the auxiliary ring 2 is displaced. At this time, the first hinge 4, which is fixedly connected to the auxiliary ring 2, moves accordingly. The first hinge 4 drives the second hinge 5 to rotate around the second connecting shaft 22 through the first connecting shaft 21. During this process, the first torsion spring 6, which is fixedly connected to the outside of the first connecting shaft 21 and the outside of the second hinge 5, will undergo elastic deformation due to the relative rotation between the first connecting shaft 21 and the second hinge 5. At the same time, the second torsion spring 14, which is fixedly connected to the inside of the second hinge 5 and the fixed plate 3, will also undergo elastic deformation due to the rotation of the second hinge 5 around the second connecting shaft 22. The elastic potential energy generated by the first torsion spring 6 and the second torsion spring 14 can effectively buffer the impact of external force, converting part of the impact energy into the elastic potential energy of the spring, thereby reducing the direct impact on the main structure.

[0038] Example 2: Figures 6-9The technical solution shown in the invention provides the following technical solution: a steel-wood hybrid structure energy-dissipating and vibration-damping node component and assembly method, which discloses that an auxiliary mechanism is provided inside the positioning shell 1 and inside the buffer mechanism. The auxiliary mechanism uses a general buffering force to drive the abutment airbag 10 to deform and further buffer the main structure. The auxiliary mechanism includes an abutment airbag 10, which is fixedly connected to the inside of the positioning shell 1, and the outside of the abutment airbag 10 is in contact with the outer wall of the main structure. In a stable state, the inside of the abutment airbag 10 does not contact the positioning shell 1. At the same time, a connecting pipe 8 is connected through the side of the abutment airbag 10. A fixing plate 3 is fixedly connected to... A fixed box 7 is provided, and the side of the fixed box 7 is connected to the other end of the connecting pipe 8. An air supply plate 18 is slidably connected inside the fixed box 7. A connecting rod 17 is fixedly connected to the lower end of the air supply plate 18. The connecting rod 17 is slidably connected to the lower side of the fixed box 7. A pull plate 19 is fixedly connected to the lower end of the connecting rod 17. A return spring 20 is fixedly connected between the lower surface of the air supply plate 18 and the interior of the fixed box 7. An auxiliary shaft 16 is fixedly connected to the outer end of the first connecting shaft 21. A traction cable 15 is fixedly connected to the outer side of the auxiliary shaft 16. The other end of the traction cable 15 is fixedly connected to the lower part of the pull plate 19. In a stable state, the air supply plate 18 is located above the fixed box 7.

[0039] As the first connecting shaft 21 rotates due to the impact on the main structure, causing the upper end of the second hinge 5 to move up and down, the auxiliary shaft 16, which is fixedly connected to its outer end, will simultaneously perform circular motion. Since one end of the traction cable 15 is fixed to the outside of the auxiliary shaft 16 and the other end is fixed below the pull plate 19, the movement of the auxiliary shaft 16 will generate a pulling force on the traction cable 15. Under the action of this pulling force, the pull plate 19 will overcome the initial elastic force of the return spring 20 and drive the air supply plate 18 to slide vertically downward inside the fixed box 7 through the connecting rod 17 fixedly connected to it. As the air supply plate 18 moves downward, the gas space inside the fixed box 7 located below the air supply plate 18 is compressed, and the gas pressure increases. Under the action of the gas, the compressed gas in the fixed box 7 is forced into the interior of the contact airbag 10 through the connecting pipe 8. The contact airbag 10, which was originally in a stable state and whose inner side did not contact the positioning shell 1, gradually expands and deforms after being continuously filled with gas. The expanded contact airbag 10 will exert a greater wrapping force and squeezing force on the outer wall of the main structure it is attached to. This pressure can not only further limit the shaking of the main structure, but also absorb and buffer the vibration energy transmitted to the main structure by utilizing the compressibility of the gas and the elasticity of the airbag material itself. It can convert a part of the mechanical energy into the internal energy of the gas and the elastic potential energy of the airbag material, thereby achieving the further dissipation of the remaining impact energy after the initial buffering.

[0040] Example 3: Figures 3-5The present invention provides the following technical solution: a steel-wood hybrid structure energy-dissipating and vibration-damping node component and assembly method, wherein a movable groove 9 is provided inside the positioning shell 1, and abutment plates 13 are fixedly connected to the front and rear sides inside the positioning shell 1, and the left and right ends of the abutment plates 13 are slidably connected inside the movable groove 9, and the middle part of the abutment plates 13 is attached to the outer side of the main structure, and the edge of the abutment plates 13 is set in an arc shape. An auxiliary plate 11 is fixedly connected to the two sides inside the abutment airbag 10, and an abutment rod 12 is slidably connected inside the movable groove 9, and the edge of the abutment rod 12 is set in an arc shape. One end of the abutment rod 12 is located between the auxiliary plate 11 and the positioning shell 1, and the other end of the abutment rod 12 is set towards the arc-shaped end of the abutment plate 13.

[0041] When the airbag 10 expands under the action of the auxiliary mechanism, the auxiliary plates 11 fixedly connected to both sides inside it will move with the expansion of the airbag. Since there is an abutment rod 12 between the auxiliary plate 11 and the positioning shell 1, the opening action of the auxiliary plate 11 will generate an outward pushing force on the abutment rod 12. Under the action of this pushing force, the abutment rod 12 will slide along the movable groove 9 opened inside the positioning shell 1 towards the abutment plate 13. The side of the abutment rod 12 is designed with an arc structure, which just matches the arc structure of the edge of the abutment plate 13. When the abutment rod 12 slides to contact the arc end of the abutment plate 13, it will apply a pushing force to the arc end of the abutment plate 13. Since the left and right ends of the abutment plate 13 are slidably connected in the movable groove 9, and the middle is connected to the main... The outer side of the body structure is attached. Under the pushing action of the abutment rod 12, the abutment plate 13 will overcome the friction between itself and the main structure and its own inertia, and move further towards the main structure along the movable groove 9. This approaching action can significantly enhance the clamping force and stabilizing effect on the main structure. Through the increased positive pressure between the abutment plate 13 and the outer wall of the main structure, the lateral displacement that the main structure may produce under impact or vibration is effectively limited. Thus, together with the initial buffering achieved by the buffer mechanism through the first torsion spring 6 and the second torsion spring 14, and the gas and elastic buffering achieved by the auxiliary mechanism through the abutment airbag 10, a multi-synergistic energy dissipation and vibration reduction system is formed, which significantly improves the overall energy dissipation and vibration reduction effect of the node components and ensures the stability and safety of the main structure under complex stress conditions.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
