Description

Technical Field

[0001] This invention relates to the field of building equipment technology, and in particular to a self-resetting buckling restraint brace. Background Technology

[0002] Buckling-restrained braces (also called buckling-resistant braces) are seismic-resistant building components with dual functions of energy dissipation and load bearing. Their core advantage is that they do not buckle under compression and have consistent tensile and compressive properties, which can protect the main structure like a "fuse".

[0003] Traditional buckling-restrained braces typically employ a single elastic element reset scheme, relying solely on their own elastic potential energy as the reset force. During moderate to strong earthquakes, the buckling plate undergoes significant elastoplastic deformation, making it difficult for the brace itself to provide sufficient driving force to quickly return to its initial position. This not only results in low reset efficiency and prolonged reset time but may also prevent the brace from promptly restoring its seismic performance due to residual deformation, severely impacting the subsequent safety of the building structure. Summary of the Invention

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] The self-resetting buckling restraint brace disclosed in this invention is mainly used to address the pain points of traditional buckling restraint braces, which only elastically reset themselves and cannot quickly return to their original position after large deformation.

[0027] Reference Figures 1-8 A self-resetting buckling restraint brace includes a fixed outer shell 1, with multiple sliding plates 3 fixedly connected to the inner side of the fixed outer shell 1. Movable inner shells 2 are provided inside both ends of the fixed outer shell 1. Filling material plates 11 are provided inside the fixed outer shell 1, and the outer sides of the movable inner shells 2 are slidably connected to the opposite side of the sliding plates 3. A buckling plate 13 is provided inside the fixed outer shell 1, with connecting outer frames 8 fixedly connected to both ends of the buckling plate 13. Multiple reset components 12 are provided inside the fixed outer shell 1. Each reset component 12 includes a reset straight plate 1201, which contacts the outer side of the buckling plate 13. Positioning center members 1207 are provided on both sides of the buckling plate 13, with the opposite sides of the positioning center members 1207 fixedly connected to the interior of the filling material plates 11.

[0028] Reference Figure 3 and Figure 6In a preferred embodiment, a plurality of connecting rods 1202 are fixedly connected to the side of the reset straight plate 1201 away from the buckling plate 13. One end of each of the symmetrical connecting rods 1202 is fixedly connected to a support plate 1203, and an electric telescopic rod 1204 is fixedly connected to the side of the support plate 1203 away from the reset straight plate 1201. The end of the electric telescopic rod 1204 away from the support plate 1203 is fixedly connected to the interior of the filling material plate 11.

[0029] In this invention, two extension rods 1205 are fixedly connected to one side of the support plate 1203, and multiple return springs 1206 are fixedly connected to one side of the support plate 1203. The return springs 1206 are all located outside the extension rods 1205. One end of the return springs 1206 and the extension rods 1205 are fixedly connected to the inside of the filling material plate 11. Multiple drive motors 1208 are provided on the side of the return plate 1201 near the support plate 1203, and the power output shafts of the drive motors 1208 are all connected to the drive gears 1209 through couplings. Movable gears 1210 are provided on the outside of the drive gears 1209, and the movable gears 1210 and the drive gears 1209 are meshed through tooth grooves.

[0030] In this invention, a rotating rod 1211 is fixedly connected inside the movable gear 1210. One end of the rotating rod 1211 is movably connected to the side of the reset straight plate 1201 away from the support plate 1203. An auxiliary positioning plate 1212 is fixedly connected to the outer side of the rotating rod 1211. The buckling plate 13 is located between the reset straight plate 1201 and the support plate 1203.

[0031] Specifically, as the seismic energy gradually dissipates and the internal stress of the buckling plate 13 drops below the critical value, the electric telescopic rod 1204 begins to extend, pushing the reset plate 1201 towards the buckling plate 13 via the connecting rod 1202. During the process of the reset plate 1201 approaching the buckling plate 13, the drive motor 1208 starts synchronously, driving the drive gear 1209 to rotate. The drive gear 1209 drives the movable gear 1210 to rotate through tooth meshing, thereby causing the rotating rod 1211 to rotate 90 degrees. The auxiliary positioning plate 1212 connected to the rotating rod 1211 then rotates from its initial vertical state to a straight line completely parallel to the reset plate 1201. When the reset plate 1201 and the surface of the buckling plate 13... Upon contact, the auxiliary positioning plate 1212 fits tightly against both sides of the positioning center piece 1207. This precise contact positioning mechanism ensures that the reset plate 1201 always pushes the buckling plate 13 to reset along the preset straight trajectory, effectively avoiding lateral displacement and jamming risks during the reset process. During the reset process, the reset spring 1206 and the extension rod 1205 play important buffering and guiding roles. The reset spring 1206 is moderately compressed during the movement of the support plate 1203, storing elastic potential energy. When the reset is nearing completion, the energy is released to achieve flexible reset and avoid rigid impact. The extension rod 1205 provides precise linear guidance for the movement of the support plate 1203, ensuring the smoothness and reliability of the reset action.

[0032] It should be noted that the dual-power reset design has high reset efficiency and stable reset effect. The electric telescopic rod 1204 provides active driving force, which can quickly push the reset plate 1201 to fit against the buckling plate 13 to apply force for reset. Combined with the passive elastic force assistance of the reset spring 1206, it can not only complete the reset action efficiently, but also avoid the problems of reset jamming and untimely reset in the single power mode.

[0033] In practical applications, the positioning center component 1207 provides the core reference for the reset action. The auxiliary positioning plate 1212, after adjusting its angle through gear transmission, forms a linear constraint with the reset plate 1201 and is in close contact with the positioning center component 1207, thus limiting the reset trajectory throughout the entire process.

[0034] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8In a preferred embodiment, a plurality of buckling range constraint components 10 are disposed inside the filling material plate 11. The buckling range constraint component 10 includes an arc-shaped constraint plate 1005. A buckling plate 13 is located between the arc-shaped constraint plate 1005 and the reset straight plate 1201. A connecting plate 1004 is fixedly connected to the side of the arc-shaped constraint plate 1005 away from the buckling plate 13. A movable frame 1003 is fixedly connected to the side of the connecting plate 1004 away from the arc-shaped constraint plate 1005. A telescopic electric rod 1001 is fixedly connected to the side of the movable frame 1003 away from the connecting plate 1004. One end of the telescopic electric rod 1001 is fixedly connected to the inside of the filling material plate 11.

[0035] In this invention, two spring rods 1002 are fixedly connected to the side of the movable frame 1003 near the telescopic electric rod 1001. One end of each spring rod 1002 is fixedly connected to the inside of the filling material plate 11. A rectangular hole is opened inside the arc-shaped constraint plate 1005. Multiple fixing rods 1006 are fixedly connected inside the rectangular hole. Movable shaft rods 1007 are movably connected to the outside of each fixing rod 1006.

[0036] In this invention, two servo motors 1008 are provided on one side of the arc-shaped constraint plate 1005. The power output shafts of the servo motors 1008 are connected to movable rods 1010 via couplings. Annular members 1009 are movably connected to the outer side of each movable rod 1010. The opposite sides of the annular members 1009 are fixedly connected to both sides of the connecting plate 1004. Two rotating members 1011 are fixedly connected to the outer side of each movable rod 1010. The annular members 1009 are located between the two rotating members 1011. An arc adjustment plate 1012 is fixedly connected to the opposite side of each rotating member 1011. The arc adjustment plate 1012 is in contact with the buckling plate 13.

[0037] Specifically, while the buckling plate 13 undergoes plastic deformation, the telescopic electric rod 1001 pushes the movable frame 1003 to move smoothly towards the buckling plate 13. The connecting plate 1004, connected to the movable frame 1003, then moves the arc-shaped constraint plate 1005 closer to the surface of the buckling plate 13. When the arc-shaped constraint plate 1005 contacts the buckling plate 13, the movable shafts 1007 inside the arc-shaped constraint plate 1005 begin to function. These movable shafts 1007 rotate adaptively around the fixed rod 1006, always maintaining perfect contact with the wavy deformed surface of the buckling plate 13, forming the first... A flexible constraint defense line is formed. At the same time, the servo motor 1008 starts and drives the movable rod 1010 to rotate slowly. The movable rod 1010 maintains stable rotation under the precise limit of the ring part 1009, which in turn drives the outer rotating part 1011 to adjust the angle. The curvature adjustment plate 1012 deflects accordingly and fits against the wavy deformation position of the buckling plate 13. This dynamic fitting mechanism can adjust the constraint curvature according to the real-time deformation shape of the buckling plate 13, ensuring that uniform constraint force can be provided at any deformation stage, and avoiding excessive deformation or even fracture failure of the buckling plate 13 due to local stress concentration.

[0038] It should be noted that the dynamic adaptation to buckling deformation and precise constraint without blind spots are achieved. The arc-shaped constraint plate 1005 is designed to fit the characteristics of the buckling plate 13, and the movable shaft 1007 adapts to the rotation and fits. It can adjust the fitting state in real time to follow the wave-shaped elastic-plastic deformation of the buckling plate 13, and achieve arc-shaped full-coverage constraint throughout the entire deformation process. This completely solves the pain points of traditional constraint structures, such as fixed shape, inability to adapt to the dynamic deformation of the buckling plate 13, and lack of local constraint, and eliminates the fracture failure caused by local protrusions or bends of the buckling plate 13.

[0039] In practical applications, the curved constraint plate 1005 is driven to fit and limit from the outside, and the curvature adjustment plate 1012 clamps from both sides of the deformable concave and convex surfaces. The dual constraints together limit the maximum deformation range of the buckling plate 13, preventing irreversible damage to the buckling plate 13 due to excessive buckling exceeding the material's tolerance limit.

[0040] Reference Figures 1-4 In a preferred embodiment, sealing plates 4 are fixedly connected to opposite sides of the movable inner shell 2, and welding plates 5 are provided on opposite sides of the sealing plates 4. Multiple round holes are provided on the welding plates 5, and bolt fasteners 6 are provided inside the round holes. Cross-shaped holes are provided on the welding plates 5, and connecting outer frames 8 are movably connected to the inside of the cross-shaped holes. Multiple sliding parts 7 are fixedly connected to opposite sides of the welding plates 5, and connecting outer frames 8 are movably connected between the multiple sliding parts 7. A fireproof enclosure 9 is provided inside the fixed outer shell 1. The inner side of the fireproof enclosure 9 is fixedly connected to the outer side of the filling material plate 11, and the buckling plate 13 is located inside the filling material plate 11.

[0041] Working principle: The enormous energy generated by an earthquake is rapidly transmitted to the support device through the main structure of the building, triggering a chain reaction in the entire support system. First, the seismic force acts on the connecting frame 8 at both ends of the fixed shell 1. This force is instantly transmitted to the buckling plate 13. As energy continues to be input, the internal stress of the buckling plate 13 continues to accumulate. When the stress exceeds the yield strength, the buckling plate 13 begins to enter the elastoplastic deformation stage. This controlled plastic deformation is the key mechanism for energy dissipation in the support. Through crystal slip and dislocation movement inside the material, the seismic energy is converted into heat energy and slowly released, thereby effectively reducing the impact of earthquakes on the building structure. As the buckling plate 13 undergoes plastic deformation, the telescopic electric rod 1001 pushes the movable frame 1003 to move smoothly towards the buckling plate 13. The connecting plate 1004, connected to the movable frame 1003, then moves the arc-shaped constraint plate 1005 closer to the surface of the buckling plate 13. When the arc-shaped constraint plate 1005 contacts the buckling plate 13, the movable shafts 1007 inside the arc-shaped constraint plate 1005 begin to function. These movable shafts 1007 rotate adaptively around the fixed rod 1006, always maintaining perfect contact with the wavy deformed surface of the buckling plate 13, forming the first flexible... The constraint line is in place. At the same time, the servo motor 1008 starts and drives the movable rod 1010 to rotate slowly. The movable rod 1010 maintains stable rotation under the precise limit of the ring part 1009, which in turn drives the outer rotating part 1011 to adjust the angle. The curvature adjustment plate 1012 deflects accordingly and fits against the wavy deformation position of the buckling plate 13. This dynamic fitting mechanism can adjust the constraint curvature according to the real-time deformation shape of the buckling plate 13, ensuring that uniform constraint force can be provided at any deformation stage, and avoiding excessive deformation or even fracture failure of the buckling plate 13 due to local stress concentration. As the seismic energy gradually dissipates and the internal stress of the buckling plate 13 drops below the critical value, the electric telescopic rod 1204 begins to extend, pushing the reset straight plate 1201 towards the buckling plate 13 via the connecting rod 1202. During the process of the reset straight plate 1201 approaching the buckling plate 13, the drive motor 1208 starts synchronously, driving the drive gear 1209 to rotate. The drive gear 1209 drives the movable gear 1210 to rotate through tooth meshing, thereby causing the rotating rod 1211 to rotate 90 degrees. The auxiliary positioning plate 1212, connected to the rotating rod 1211, rotates from its initial vertical state to a straight line completely parallel to the reset straight plate 1201. When the reset straight plate 1201 contacts the surface of the buckling plate 13... At the same time, the auxiliary positioning plate 1212 fits tightly against both sides of the positioning center piece 1207. This precise contact positioning mechanism ensures that the reset plate 1201 always pushes the buckling plate 13 to reset along the preset straight trajectory, effectively avoiding the risk of lateral displacement and jamming during the reset process. During the reset process, the reset spring 1206 and the extension rod 1205 play important buffering and guiding roles. The reset spring 1206 is moderately compressed during the movement of the support plate 1203, storing elastic potential energy. When the reset is close to completion, the energy is released to achieve flexible reset and avoid rigid impact. The extension rod 1205 provides precise linear guidance for the movement of the support plate 1203, ensuring the smoothness and reliability of the reset action. The movable inner shell 2 slides smoothly on the sliding plate 3 via the sliding member 7, providing the necessary expansion and contraction space for the support device. The sealing plate 4 fits tightly against the joint between the movable inner shell 2 and the fixed outer shell 1, effectively preventing external dust, moisture, and particles of the filling material plate 11 from entering the support. The welding plate 5 is firmly connected to the fixed outer shell 1 via bolt fasteners 6, providing a stable support platform for the connecting outer frame 8. At the same time, its specially designed cross-shaped hole allows the connecting outer frame 8 to make moderate axial displacement under seismic action. The fireproof enclosure 9 and the filling material plate 11 constitute the last line of defense for the support system. The fireproof enclosure 9 is made of high-temperature resistant fireproof material, which can effectively block the spread of flames in the event of a fire and protect the core components of the support from high-temperature damage. The filling material plate 11 fills all the gaps inside the fireproof enclosure 9, which not only provides good heat insulation performance, but also absorbs some vibration energy during an earthquake, further improving the energy consumption efficiency of the support system.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
