Description

Technical Field

[0001] This invention relates to the field of curtain wall connectors, specifically an adaptive damping curtain wall connector. Background Technology

[0002] As modern buildings develop towards high-rise and large-span structures, the problems of wind-induced vibration and seismic response of curtain wall structures are becoming increasingly prominent. Traditional curtain wall connectors mostly adopt rigid or fixed damping designs, which are difficult to adapt to complex and ever-changing environmental loads. Currently, Chinese invention publication CN108643406B discloses a double-layer curtain wall damping system, including an inner curtain wall, an outer curtain wall, connecting rods, tracks, sliders, springs, buffer materials, and fasteners. Under slight vibration, the sliders slide slightly, and energy is absorbed by the deformation of the springs between the sliders. Under severe vibration and impact, the sliders slide rapidly, causing the connecting rods to open and close rapidly. The movement speed and distance of the outer curtain wall increase dramatically, and the energy dissipation effect is significantly increased, fully utilizing the damping and vibration reduction effect. The aforementioned double-layer curtain wall damping system absorbs energy through spring deformation. However, when the spring absorbs energy and then returns to its original position due to elastic potential energy, it increases its vibration and cannot effectively reduce curtain wall vibration. The damping performance of the buffer material is not adjustable, making it unable to cope with sudden strong winds. Furthermore, the curtain wall is connected and supported by connecting rods, which means that the buffer material can only buffer the curtain wall in a single direction of movement and only absorbs uniaxial displacement. In strong wind environments with different wind directions and in the event of an earthquake, it cannot provide effective buffering. Summary of the Invention

[0018] Please see Figure 1 An adaptive damping curtain wall connector of the present invention includes a magnetorheological fluid damper assembly 1, which is fixed on the keel frame 2 and connected to the curtain wall panel 4 through a connector 3. The connector 3 is used to connect the connecting rod assembly 13 and the curtain wall panel 4. The connector 3 is a mature existing technology. By using conventional curtain wall connectors and connection methods available on the market, a stable connection between the connecting rod assembly 13 and the curtain wall panel 4 can be achieved. Each curtain wall panel 4 is connected to at least four magnetorheological damper assemblies 1 to ensure a stable support effect for the curtain wall panel 4.

[0019] Please see Figure 2 The magnetorheological fluid damper assembly 1 includes a housing 11, a spherical magnetorheological fluid damper 12, a connecting rod assembly 13, a tension spring 14, an end cap 15, a support rod assembly 16, and a connecting plate 17. The spherical magnetorheological fluid damper 12 is disposed on the right side inside the housing 11. The center of the spherical magnetorheological fluid damper 12 is penetrated by the connecting rod assembly 13, and the left end of the connecting rod assembly 13 is elastically connected to the end cap 15 through the tension spring 14. The end cap 15 is fixed to the left side of the housing 11. The support rod assembly 16 is connected to the top right side of the connecting rod assembly 13, and the top end of the support rod assembly 16 is connected to the housing 11. The connecting plate 17 is fixed to the bottom end of the housing 11, and the connecting plate 17 is locked to the keel frame 2 by bolts. The right end of the connecting rod assembly 13 is connected to the curtain wall panel 4 through the connector 3. Please see Figure 3-5The spherical magnetorheological fluid damper 12 includes a rotating ball 121, a spherical shell 122, a magnetorheological fluid 123, a sealing ring 124, a fixed shell 125, and an electromagnetic coil 126. The rotating ball 121 is embedded in the spherical shell 122. The left and right sides of the spherical shell 122 are hollowed out, and the space between the spherical shell 122 and the rotating ball 121 is filled with magnetorheological fluid 123. Sealing rings 124 are provided at both ends of the space between the spherical shell 122 and the rotating ball 121. The magnetorheological fluid 123 is encapsulated between the rotating ball 121 and the spherical shell 122 through the sealing rings 124. The fixed shell 125 is fitted on the outer wall of the spherical shell 122, and the electromagnetic coil 126 is provided inside the fixed shell 125. The fixed shell 125 is embedded in the right side of the outer shell 11, and the fixed shell 125 is fixedly connected to the outer shell 11. The inner wall of the fixed shell 125 has a cavity, and the electromagnetic coil 126 is disposed in the cavity inside the fixed shell 125. The electromagnetic coil 126 is evenly distributed along the outer wall of the spherical shell 122. At least four protruding blocks are provided on the inner wall of the fixed shell 125 and are fixedly connected to the spherical shell 122 to ensure a stable connection between the fixed shell 125 and the spherical shell 122. The sealing ring 124 has three layers: an inner polytetrafluoroethylene lip sealing ring, a middle nano-graphite filled O-ring, and an outer laser-welded titanium alloy edge seal. 1. The inner PTFE lip seal is the main dynamic sealant, and its function is as follows: Low-friction sliding: The coefficient of friction of PTFE is only 0.05-0.1, allowing the rotating ball 121 to rotate without jamming within a ±30° rotation angle; Pressure adaptive: Magnetorheological fluid pressure pushes the lip to fit tightly against the spherical surface; the greater the pressure, the tighter the seal. 2. The middle layer of nano-graphite O-rings serves multiple functions for compensation: Conductivity: Nano-graphite filling reduces the rubber resistance to 10²-10³ Ω·m, dissipating tribostatic electricity; Thermal expansion compensation: Graphite thermal conductivity >100 W / m·K, quickly equalizes the temperature in the sealing area; It compensates for manufacturing errors in PTFE lip seals and prevents fluid leakage along the axial gap; 3. The outer titanium alloy edge sealing is a rigid protective terminal: Extrusion resistance: Titanium alloy yield strength ≥800 MPa, preventing O-rings from being squeezed into the shell gap under high pressure; Corrosion resistance: The passivation film resists acidic additives in magnetorheological fluids; Laser welding depth is 0.3-0.5mm, and the heat-affected zone must be controlled to be <50μm to avoid high temperature damage to the inner sealing components; Magnetorheological fluid 123 is a smart material composed of suspended magnetic particles, carrier liquid and functional additives. It includes magnetic particles, carrier liquid, dispersant, anti-settling agent and antioxidant. Magnetorheological fluid 123 is a mature existing technology and will not be described in detail.

[0020] The outer side of the housing 11 is provided with a power connection port for connecting to an external power supply device, and the power connection port is electrically connected to the electromagnetic coil 126. The electromagnetic coil 126 is energized by the external power supply device to change the characteristics of the magnetorheological fluid 123.

[0021] Please see Figure 6 The connecting rod assembly 13 includes a diagonal rod 131, a through rod 132, a connecting block 133, and a straight rod 134. The left end of the diagonal rod 131 is provided with the through rod 132, which passes through the rotating ball 121, and the left end of the through rod 132 is fixedly connected to the connecting block 133. The right end of the diagonal rod 131 is provided with the straight rod 134, and the right end of the straight rod 134 is connected to the curtain wall panel 4 through the connector 3. The left end of the connecting block 133 is elastically connected to the end cap 15 through a tension spring 14.

[0022] The diagonal rod 131, the through rod 132 and the straight rod 134 are integrally formed, and the diagonal rod 131 and the through rod 132 are inclined. The diagonal rod 131, the through rod 132 and the outer shell 11 are all inclined downward from left to right. When the curtain wall panel 4 is not under force, the diagonal rod 131, the through rod 132 and the tension spring 14 are arranged in the same straight line. When the curtain wall panel 4 is rotated at any angle, the rotating ball 121 is driven to rotate through the connecting rod assembly 13, and the connecting rod assembly 13 pulls the tension spring 14, increasing the elastic potential energy of the tension spring 14. The elastic potential energy generated by the tension spring 14 resets the through rod 132 and the rotating ball 121, that is, resets the curtain wall panel 4. The rotating ball 121 has a through hole in its inner center that fits with the through rod 132. The outer diameter of the inclined rod 131 is larger than that of the through rod 132. The left end of the inclined rod 131 and the right end of the connecting block 133 abut against the left and right ends of the rotating ball 121 respectively, ensuring the connection effect between the rotating ball 121 and the connecting rod assembly 13.

[0023] Please see Figure 7-8The support rod assembly 16 includes a straight tube 161, a slider 162, a movable rod 163, a tension spring 164, a connecting piece 165, a rotating shaft 166, a bearing 167, and a connecting piece 168. The slider 162 is embedded in the front of the inside of the straight tube 161. The top end of the movable rod 163 extends into the straight tube 161 and is fixedly connected to the slider 162. The top of the slider 162 is elastically connected to the top end of the inside of the straight tube 161 through the tension spring 164. The top end of the straight tube 161 is rotatably connected to the connecting piece 165 through the rotating shaft. The connecting piece 165 is welded to the right side of the rotating shaft 166. The rotating shaft 166 is rotatably connected to the top wall of the outer casing 11 through the bearing 167. The bottom end of the movable rod 163 is rotatably connected to the connecting piece 168 through the rotating shaft, and the connecting piece 168 is fixedly connected to the inclined rod 131.

[0024] The center of the rotating shaft 166 is aligned with the center of the rotating ball 121. The slider 162 is in contact with the inner wall of the straight tube 161, and the straight tube 161 is parallel to the movable rod 163. When the curtain wall panel 4 is not under force, the slider 162 is located in the middle of the inner side of the straight tube 161. When the curtain wall panel 4 moves, the slider 162 moves up or down along the inner wall of the straight tube 161 according to its direction of movement.

[0025] This invention provides an improved adaptive damping curtain wall connector, the working principle of which is as follows; First, the magnetorheological fluid damper assembly 1 is installed. The connecting plate 17 of the magnetorheological fluid damper assembly 1 is fixed to the pre-set keel frame 2 of the building exterior wall by bolts. The straight rod 134 of the magnetorheological fluid damper assembly 1 is fixedly connected to the curtain wall panel 4 by the connector 3. The electromagnetic coil 126 is electrically connected to the external power supply equipment through the power connection port. Second, the electromagnetic coil 126 is energized as needed. In a strong wind environment, when energized (1A), the electromagnetic coil 126 generates a magnetic field strength of 0.4 T, and the magnetorheological fluid 123 is in a semi-solid state. In a strong earthquake environment, when energized (2A), the electromagnetic coil 126 generates a magnetic field strength of 0.8 T, and the magnetorheological fluid 123 is in a near-solid state. When not energized, the magnetorheological fluid 123 is in a Newtonian fluid state. Power is applied as needed according to different environments to change the shape of the magnetorheological fluid 123 and generate different resistances to the rotating ball 121.

[0026] 1. When the curtain wall panel 4 is displaced, the displacement of the curtain wall panel 4 in any direction will cause the rotating ball 121 to rotate through the connecting rod assembly 13: When the curtain wall panel 4 moves in the front and rear directions, it drives the connecting rod assembly 13 to rotate in the same direction through the connector 3, and the connecting rod assembly 13 drives the rotating ball 121 and the support rod assembly 16 to rotate in the same direction. When the curtain wall panel 4 moves up and down, the connecting rod assembly 13 drives the rotating ball 121 to rotate in the same direction, and the support rod assembly 16 extends or retracts. When the curtain wall panel 4 moves in the left and right directions, the inclined rod 131 and the through rod 132 of the connecting rod assembly 13 are inclined, causing the curtain wall panel 4 to move laterally and drive the rotating ball 121 to rotate in the up and down directions.

[0027] Fourth, the rotating ball 121 is reset by the self-weight of the curtain wall panel 4 and the elastic potential energy generated by tension spring 14 and tension spring 164, that is, the curtain wall panel 4 is reset.
