Description

Technical Field

[0001] This application belongs to the field of building structure and curtain wall engineering technology, specifically relating to an integrated seismic isolation and resetting composite bearing system and a canopy. Background Technology

[0002] In modern large-scale public buildings, long-span canopy structures often cover multiple independent structural units. The underlying main structures may experience significant differences in deformation under the influence of loads, settlement, temperature, and seismic forces. Traditional connection methods are ill-suited to such large deformation conditions and have the following obvious limitations: 1. Rigid Connection: The canopy support structure is rigidly connected to the lower main structure. This method creates a strong constraint relationship between the canopy and the main structure. Differential deformation can cause significant additional internal forces within the canopy system, which may lead to component damage, node failure, or membrane tearing, posing a high safety risk.

[0003] 2. Pure sliding bearing connection: For example, using PTFE sliding bearings, only the horizontal constraint is relieved. Its main drawback is the lack of a reset mechanism. After sliding occurs, the structure will produce irreversible residual displacement, which can easily cause the canopy system to deviate from the design position over a long period of time, affecting drainage performance, sealing effect, appearance and function, and making it difficult to adapt to repeated loads (such as wind vibration and aftershocks).

[0004] 3. Conventional seismic isolation bearings: such as rubber seismic isolation bearings, have limited design displacement capacity, making it difficult to meet the ultra-large deformation requirements in such projects. Their recovery capacity depends on the elastic properties of the rubber material, and the recovery force is significantly weakened after large deformation, also resulting in residual displacement issues.

[0005] 4. Simple spring support: Although it can provide a certain restoring force, it lacks an effective energy dissipation mechanism. Under dynamic loads, it is prone to continuous vibration and lacks a reliable limiting device, posing a risk of instability.

[0006] In summary, existing connection technologies lack a support system that can simultaneously meet the requirements of "large displacement adaptability, high energy efficiency, precise reset function and multi-directional deformation compatibility", which restricts the safe implementation of complex shapes and ultra-long structures in engineering.

[0026] Example 1 A specific embodiment of the present invention discloses an integrated seismic isolation and reset composite bearing system, which can be referred to as the "composite bearing system". The composite bearing system 100 adopts an integrated structure of "seismic isolation damping mechanism + horizontal sliding mechanism + bidirectional elastic reset mechanism", and the whole is a modular forged component that can be directly connected to the canopy steel frame.

[0027] like Figures 1 to 5As shown, the composite support system includes a main support frame, a horizontal sliding mechanism, a seismic isolation damping mechanism, and a bidirectional elastic reset mechanism. The main support frame is a steel ring beam 1, which is integrally forged from high-strength steel. The horizontal sliding mechanism has a steel support base 11 and a horizontal directional steel track 10 mounted on the steel support base 11. The seismic isolation damping mechanism connects the steel ring beam 1 and the horizontal sliding mechanism, allowing relative displacement between them in the horizontal Y direction. The bidirectional elastic reset mechanism has a vertical elastic component and a lateral reset component. The vertical elastic component is configured to allow relative displacement between the steel ring beam 1 and the horizontal sliding mechanism in the vertical Z direction. The top of the vertical elastic component is connected to the seismic isolation damping mechanism, and the bottom of the vertical elastic component slides on the horizontal directional steel track 10, enabling horizontal X-direction sliding displacement. The lateral reset component connects the main steel structure 12 and the steel ring beam 1, enabling horizontal Y-direction reset.

[0028] Figure 1 and Figure 3 The X, Y, and Z directions are shown.

[0029] In this embodiment, the seismic isolation damping mechanism is connected between the steel structure ring beam 1 and the horizontal sliding mechanism, which can dissipate the vibration energy of the main structure, realize the seismic isolation function, and effectively block the transmission of vibration to the canopy structure.

[0030] Specifically, the seismic isolation damping mechanism includes a first polytetrafluoroethylene (PTFE) 4 and a steel sleeve 5; the steel sleeve 5 has a first cylindrical body 5.1 and a first steel plate 5.2, one end of the first cylindrical body 5.1 is vertically fixedly connected to the first steel plate 5.2, and the first steel plate 5.2 is connected to the steel structure ring beam 1 through a connecting assembly 6; the first PTFE 4 is disposed between the first steel plate 5.2 and the bottom surface of the steel structure ring beam 1; the first steel plate 5.2 is provided with an elongated pre-reserved hole 5.2.1 extending in the Y direction, and the elongated pre-reserved hole 5.2.1 corresponds to the pre-reserved waist-shaped hole on the first PTFE gasket 4; The connecting assembly 6 includes a fixing bolt 6.1, a steel washer 6.2, a second polytetrafluoroethylene washer 6.3, and a nut 6.4. The fixing bolt 6.1 passes through the elongated pre-drilled hole 5.2.1 on the first steel plate 5.2 and the bolt hole on the steel structure ring beam 1, and is then fixed by the nut 6.4. The second polytetrafluoroethylene washer 6.3 is disposed between the steel washer 6.2 and the bottom surface of the first steel plate 5.2.

[0031] In this embodiment, the vertical elastic component includes a gravity balance spring 7 and a steel sleeve core 8. The steel sleeve 5 can also be part of the vertical elastic component. The gravity balance spring 7 is connected between the steel sleeve core 8 and the steel sleeve 5, and the steel sleeve core 8 and the steel sleeve 5 can generate relative displacement in the Z direction and reset using the gravity balance spring 7. Through the synergistic effect of gravity and spring preload stress, the support is in a mechanical equilibrium position under normal conditions, and after deformation, it achieves precise reset by relying on the restoring force of the gravity balance spring 7.

[0032] Specifically, the steel sleeve core 8 includes a second cylinder 8.1 and a second steel plate 8.2. The bottom end of the second cylinder 8.1 is vertically and fixedly connected to the top surface of the second steel plate 8.2. The top of the second cylinder 8.1 is inserted into the first cylinder 5.1 of the steel sleeve 5. A polytetrafluoroethylene gasket can also be provided between the second cylinder 8.1 and the first cylinder 5.1. A gravity balance spring 7 is sleeved on the outside of the inserted second cylinder 8.1 and the first cylinder 5.1. The two ends of the gravity balance spring 7 abut against the first steel plate 5.2 and the second steel plate 8.2, respectively. An inverted T-shaped slider 8.3 is provided with a downward protrusion on the bottom surface of the second steel plate 8.2. The T-shaped slider 8.3 is slidably installed between two horizontal directional steel rails 10. A groove extending in the X direction is formed between the two horizontal directional steel rails 10. The T-shaped slider 8.3 can move in the X direction within the groove formed between the two horizontal directional steel rails 10.

[0033] To address the large deformation conditions at the junction of multiple buildings, a lateral reset component is added. The lateral reset component is connected between the main steel structure 12 and the steel structure ring beam 1. The lateral reset component includes a lateral reset spring 3 and a steel top rod sleeve core 2 to prevent excessive deformation.

[0034] The total stiffness of the return spring has been calculated and optimized to ensure that it can provide sufficient return force during displacement, while leaving a safety margin.

[0035] Specifically, a spring mounting cylinder 1.1 is provided on the side wall of the steel structure ring beam 1, and a reset spring 3 is installed inside the spring mounting cylinder 1.1. The center line of the hole of the spring mounting cylinder 1.1 is along the Y direction. One end of the push rod sleeve 2 extends into the spring mounting cylinder 1.1 and abuts against the reset spring 3. The other end of the push rod sleeve 2 is fixedly connected to the main steel structure 12 by bolts. In this embodiment, the horizontal sliding mechanism includes a horizontal directional steel rail 10, a steel structure support base 11, and a third polytetrafluoroethylene (PTFE) gasket 9. The third PTFE gasket 9 is a PTFE gasket for horizontal sliding and is disposed between the horizontal directional steel rail 10 and the sliding surface of the lower end of the steel sleeve core 8. Specifically, the third PTFE gasket 9 is disposed between the bottom surface of the second steel plate 8.2 and the horizontal directional steel rail 10, and between the T-shaped slider 8.3 and the horizontal directional steel rail 10. The two horizontal directional steel rails 10 are welded to the steel structure support base 11, which is vertically connected to the main steel structure 12. The lower end of the steel sleeve core 8 is slidably disposed between the two horizontal directional steel rails 10. The two horizontal steel rails 10 serve as a guide mechanism for the steel sleeve core 8 to achieve horizontal sliding displacement in the X direction, adapting to the multi-dimensional large deformation requirements of the main structure.

[0036] This embodiment also provides a canopy, which is a self-balancing canopy system. It adopts a coordinated design of "self-balancing cable system + lightweight canopy panel" and is combined with an integrated seismic isolation and reset composite support system to achieve decoupled transmission of load and deformation.

[0037] Specifically, such as Figure 6 As shown, the self-balancing canopy system includes a self-balancing cable system 200 and a canopy panel 300 mounted on the self-balancing cable system 200. The ends of the self-balancing cable system 200 are connected to the main steel structure 12 via a composite support system 100. Carbon fiber cables 202 are connected to the steel structure ring beam 1 of the composite support system 100 via fixed supports 13.

[0038] Composite bearing system 100: seismic isolation damping mechanism + horizontal sliding mechanism + bidirectional elastic reset mechanism. The main frame 1 of the bearing acts as a rigid floating unit, which can deform in tandem with the bearing and does not generate additional stress on its own.

[0039] The self-balancing cable-stayed system 200 consists of stainless steel compression members and carbon fiber cables 202. The stainless steel compression members include horizontal stainless steel tension / compression members 203 and vertical stainless steel tension / compression members 201, which are welded together by steel joints and fixed to the steel ring beam 1 of the composite support 100 by threaded anchors at both ends. By arranging this self-balancing structure of "stainless steel compression members + carbon fiber cables," the stainless steel members bear the compressive force, while the carbon fiber cables 202 bear the tensile force. The initial pretension is optimized through parametric design to ensure uniform membrane tension. This system possesses a certain degree of flexibility and can absorb minor deformations and vibration energy.

[0040] Canopy Panel 300: The canopy panel is a lightweight design, utilizing ETFE membrane material. It comprises multiple ETFE air cushion units, secured to carbon fiber cables via stainless steel clamps and aluminum strips. The stainless steel clamps are evenly distributed along the cable length, converting wind load and self-weight into uniform membrane tension. The edges of the ETFE air cushion units are sealed to the steel frame using aluminum alloy clamps, with allowance for adjustment to accommodate installation errors. For areas requiring high light transmission, double-glazed, ultra-clear tempered glass is used, bonded to the steel frame with structural adhesive. Double sealing is implemented at the panel-frame connection, and the steel frame beams are designed with a 5% drainage slope, complemented by stainless steel external drainage channels, ensuring a Class A waterproof rating.

[0041] The load and deformation transmission path of the aforementioned canopy using an integrated seismic isolation and reset composite bearing system is as follows: the canopy's self-weight and wind load are transmitted to the movable steel frame through the self-balancing cable system, and the load is transmitted to the main steel structure through the seismic isolation damping mechanism and vertical elastic components of the composite bearing system; the deformation of the main structure is absorbed by the rotation and sliding of the bearing system, and the steel frame only undergoes overall follow-up motion, thereby achieving complete decoupling of the load transmission path and deformation response.

[0042] The on-site installation steps are as follows: Step 1: When producing the steel structure ring beam 1, first fix the nut 6.4 in the designated position in advance, so that it can be connected with the fixing bolt 6.1 during subsequent assembly; Step 2: Before hoisting, install the reset spring 3 inside the spring mounting sleeve 1.1 on the steel structure ring beam 1; install the steel top rod sleeve core 2 and fix it to the main steel structure 12 with bolts; pass the fixing bolt 6.1 of the connecting component 6 through the reserved hole of the steel sleeve 5 and the reserved waist-shaped hole of the first polytetrafluoroethylene gasket 4 and fix and tighten it with the nut 6.4 inside the steel structure ring beam 1.

[0043] Step 3: Weld and fix the horizontal directional steel rail 10 to the steel structure support base 11; insert the third PTFE gasket 9 (i.e., the PTFE gasket for horizontal sliding) into the horizontal directional steel rail and fix it; slide the bottom T-shaped slider 8.3 of the steel sleeve core 8 into the groove formed by the two horizontal directional steel rails 10, and install the PTFE gasket for horizontal sliding on the sliding surface; put the gravity balance spring 7 into the second cylinder 8.1 of the steel sleeve core 8.

[0044] Step 4: After assembling the steel structure ring beam 1, steel top rod sleeve core 2, return spring 3, first PTFE gasket 4 and steel sleeve 5, put the first cylinder 5.1 of the steel sleeve 5 onto the second cylinder 8.1 of the steel sleeve core 8.

[0045] Step 5: Install the ETFE air cushion unit for the canopy.

[0046] During daily deformation caused by temperature changes, the support may slide slightly and can automatically reset.

[0047] Compared with existing technologies, the integrated seismic isolation and resetting composite bearing system and canopy provided in this embodiment can achieve at least one of the following beneficial effects: 1. Achieve integrated functions of seismic isolation, adaptation, and resetting: The composite bearing system integrates seismic isolation damping, multi-dimensional deformation adaptation, and precise resetting functions, improving seismic isolation efficiency, effectively decoupling the deformation and vibration of the main structure, avoiding secondary damage to the canopy, and is especially suitable for complex deformation areas where multiple buildings intersect.

[0048] 2. Significantly improved stability of the canopy system: Through the self-balancing cable system, the canopy as a whole becomes a "rigid floating body", and the load and deformation path are completely decoupled, which is suitable for large spans and complex deformation areas, ensuring the overall stability of the canopy system; the ETFE membrane material has reserved adjustment range and double sealing design, combined with drainage slope optimization, to ensure first-level waterproofing and membrane tension stability.

[0049] 3. Significant advantages in lightweight and energy saving: It is compatible with lightweight panels such as ETFE film, which reduces the weight of the canopy compared with traditional glass canopies, thus reducing the load on the main structure; it also improves the energy efficiency and waterproof reliability of the canopy system through panel construction and sealing performance optimization.

[0050] 4. High versatility and standardization: The spring preload and damping coefficient of the composite support can be customized and adjusted, and the canopy frame and canopy panel can be modularly designed according to project requirements, adapting to canopy projects of various large-span public buildings and reducing design and manufacturing costs.

It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
