Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a self-balancing independent column support system with a damper. Background Art

[0002] In recent years, independent column support systems have gradually evolved toward functionally resilient structures and resilient disaster prevention. Generally speaking, functionally resilient structures are based on the principles of self-reset or earthquake-damaged replaceability. Through rational design, structural damage is concentrated in removable and replaceable areas, thereby achieving post-earthquake recovery and extending the lifecycle of the building structure.

[0003] Independent column support systems generally have greater lateral stiffness and seismic energy absorption capacity, but under external loads and strong earthquakes, they often produce large residual deformations, making the structure difficult or expensive to repair. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a self-balancing independent column support system with a damper, thereby improving the ductility and energy dissipation capacity of the system and extending the life of the overall structure.

[0005] To achieve the above-mentioned purpose, one embodiment of the present invention provides a self-balancing independent column support system with a damper, including: an independent column, which realizes self-balancing by forming a self-resetting mechanism through internal tension and compression rods or inclined arrangement, and the independent column can be fixed on the lower main structure or foundation position; a support platform, which is fixed to the independent column and extends to the opposite sides of the independent column to form a first support arm and a second support arm respectively, and the support platform is formed of a thin-walled steel plate; a damper, which is detachably arranged at the end of the first support arm and / or the second support arm, and the damper can dynamically adjust the damping force according to the vibration feedback of the support platform to complete vibration reduction.

[0006] The above technical solutions achieve self-balancing of independent columns through prestressing and geometric optimization, use high-strength thin-walled steel plates to form a support platform to achieve a combination of lightweight and high strength, use damper energy dissipation for vibration reduction, and form multiple anti-vibration defense lines through the combination of local buckling deformation of steel plates and damper energy dissipation, thereby improving the ductility and energy dissipation capacity of the system. The thin-walled steel plate system reduces the use of concrete and reduces carbon emissions; the replaceable design of the damper extends the life of the overall structure, conforms to the concept of sustainability throughout the entire life cycle, and achieves low-carbon and environmental protection. By deeply integrating lightweight thin-walled structures, intelligent damping control, and self-balancing mechanical principles, a "high toughness, low environmental impact, and fast response" support system solution is formed, providing a new paradigm for flexible structure design and expanding application scenarios.

[0010] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0011] Please also refer to Figure 1~Figure 2 ,in, Figure 1 A schematic diagram of the architecture of a self-balancing independent column support system with a damper provided in one embodiment of the present invention; Figure 2 for Figure 1 Enlarged schematic diagram of part A.

[0012] like Figure 1~Figure 2 As shown, the self-balancing independent column support system with dampers described in this embodiment includes: an independent column 11, a support platform and at least one damper 13.

[0013] The independent column 11 is self-balancing by forming a self-resetting mechanism through internal tension and compression rods or an inclined arrangement. The independent column 11 can be fixed on the lower main structure 10 or the foundation position. The independent column 11 can adopt the independent column in the existing independent column support system, and form an independent column self-resetting mechanism through internal tension and compression rods or an inclined arrangement, that is, it achieves self-balancing through prestressing and geometric optimization, and automatically restores the initial position under the action of load, reducing dependence on the foundation or surrounding structures, and is particularly suitable for soft soil foundations or seismically active areas. The bottom of the independent column 11 can adopt a ball joint support, a pin connection or other articulated forms to achieve a fixed connection with the lower main structure or the foundation position.

[0014] The support platform is fixed to the independent column 11 and extends to opposite sides of the independent column 11 to form a first support arm 121 and a second support arm 122, respectively. The support platform is formed from thin-walled steel plates. Using high-strength thin-walled steel plates as the primary load-bearing and enclosing structure achieves a combination of lightweight (reducing deadweight by 30% to 50%) and high strength. Thin-walled steel plates are optimized through structural optimization such as longitudinal and transverse folding and stiffening ribs to enhance local stability and avoid the waste of traditional thick plate materials. Furthermore, the thin-walled steel plates are capable of local buckling and deformation, which can improve the ductility and vibration resistance of the system. The relatively distributed first support arm 121 and second support arm 122 on the independent column 11 can increase the overall stiffness of the self-balancing independent column support system with dampers, ensuring balanced load-bearing capacity, a clear load transmission path, significantly improved wind pressure resistance, and an aesthetically pleasing appearance.

[0015] The damper 13 is detachably mounted at the end of the first support arm 121 and / or the second support arm 122. It dynamically adjusts the damping force based on the support platform's vibration feedback to achieve vibration reduction. This dynamic damping force adjustment based on the platform's real-time vibration feedback significantly improves the platform's stability against wind, earthquake, and other mechanical vibrations. The damper's detachable design facilitates rapid post-disaster repair or replacement, thereby extending the life of the entire structure.

[0016] This embodiment achieves self-balancing of independent columns through prestressing and geometric optimization. High-strength, thin-walled steel plates form the support platform, combining lightweight design with high strength. Dampers dissipate energy for vibration reduction. The combination of local buckling deformation of the steel plates and damper energy dissipation creates multiple lines of defense against vibration, improving the system's ductility and energy dissipation. The thin-walled steel plate system reduces concrete usage and carbon emissions; the replaceable damper design extends the life of the entire structure, aligning with the concept of lifecycle sustainability and achieving low-carbon environmental protection. By integrating lightweight, thin-walled structures, intelligent damping control, and self-balancing mechanical principles, a support system solution with high toughness, low environmental impact, and rapid response is created. This solution provides a new paradigm for flexible structural design and expands its application scenarios. It is suitable for multi-hazard protection applications such as offshore platforms (for wind and wave resistance), buildings in high-intensity areas (for earthquake resistance), and precision instrument platforms (for vibration reduction). Its rapid deployment and self-balancing characteristics make it suitable for temporary emergency structures such as post-disaster emergency bridges or command centers.

[0017] In some embodiments, the thin-walled steel plates are high-strength, thin-walled steel plates, such as cold-formed steel plates or corrugated steel plates. Using high-strength, thin-walled steel plates as the primary load-bearing and enclosure structure achieves a combination of lightweight (reducing deadweight by 30% to 50%) and high strength, improving local stability and avoiding waste of traditional thick plate materials.

[0018] In some embodiments, the surface of the thin-walled steel plate has an anti-corrosion coating (such as a nano-coating), which can extend the service life of the thin-walled steel plate.

[0019] In some embodiments, the thin-walled steel plate includes: a first thin-walled sub-steel plate 141, a second thin-walled sub-steel plate 142, and a third thin-walled sub-steel plate 143. Specifically, the first thin-walled sub-steel plate 141 is laid flat along the axial direction perpendicular to the independent column 11 as the bearing surface of the support platform; the second thin-walled sub-steel plate 142 and the third thin-walled sub-steel plate 143 are arranged vertically and horizontally below the first thin-walled sub-steel plate 141 to form a support net as the support structure of the support platform. The second thin-walled sub-steel plate 142 can be fixedly connected to the lower surface of the first thin-walled sub-steel plate 141 and perpendicular to the first thin-walled sub-steel plate 141, and the third thin-walled sub-steel plate 143 and the second thin-walled sub-steel plate 142 are arranged vertically and horizontally to form a support net. That is, a support platform is formed using high-strength thin-walled steel plates as the main load-bearing and enclosing structure. Preferably, the first thin-walled sub-steel plate 141 also covers the damper 13 to prevent the damper 13 from being exposed to the external environment, thereby providing a certain degree of protection for the damper 13 .

[0020] In some embodiments, the self-balancing independent column support system with dampers further includes fiber optic sensors or wireless accelerometers (not shown) located at the intersections of the thin-walled steel plates and on the dampers to monitor the structural strain and vibration frequency of the support platform, as well as the status of the dampers. By embedding fiber optic sensors or wireless accelerometers at appropriate locations within the system for monitoring, predictive maintenance can be achieved.

[0021] In some embodiments, the thin-walled steel plate is equipped with stiffening ribs. These are strip-shaped reinforcements installed at supports or locations with concentrated loads to ensure local stability and transfer concentrated forces. They can improve the stability and torsional resistance of the beam. Optimizing the stiffening rib arrangement can improve the local stability of the thin-walled steel plate.

[0022] In some embodiments, the extended length of the first support arm 121 is greater than the extended length of the second support arm 122, and the damper 13 is detachably mounted at the end of the first support arm 121. When a single damper is provided, placing it at the end of the support arm with the longer arm length (extended length of the support arm) allows the damper to better dynamically adjust the damping force based on vibration feedback from the support platform to achieve vibration reduction, significantly improving the stability of the support platform against wind vibration, earthquakes, or mechanical vibrations.

[0023] In some embodiments, guardrails 19 are further provided at the ends of the first support arm 121 and the second support arm 122 ; the damper 13 is detachably provided at the end of the first support arm 121 and is located on the side of the guardrail 19 close to the independent column 11 .

[0024] In some embodiments, the damper 13 is a magnetorheological damper, a friction damper, or a composite damper. The use of a new type of damper can better dynamically adjust the damping force according to the vibration feedback of the support platform to achieve vibration reduction.

[0025] In some embodiments, the damper 13 is made of shape memory alloy (SMA) or superelastic material. High-performance materials can achieve the self-recovery function of the damper under large deformation.

[0026] In some embodiments, Building Information Modeling (BIM) technology can be used to precisely prefabricate thin-walled steel panels and dampers, enabling on-site assembly. This modular prefabrication can effectively reduce construction time by over 50%, making it suitable for industrialized construction.
