Description
Technical Field
[0001] This invention relates to the field of curved glass curtain wall hoisting technology, and in particular to a curved glass curtain wall hoisting device and hoisting method. Background Technology
[0002] In curved glass curtain wall projects, large-size curved glass usually refers to curtain wall glass with a certain curvature that needs to be hoisted and installed as a whole using hoisting equipment. Large-size curved glass has characteristics such as heavy weight, relatively low overall stiffness, complex curved shape, and easy deflection and posture changes during hoisting. Especially during the hoisting process, the glass is subjected to gravity, hoisting point reaction force, and wind load, and its curved posture is prone to change. This places high demands on the fit between the hanging clamp and the glass, the uniformity of the force on the hoisting points, and the control of the installation posture.
[0003] Currently, large-size curved glass is typically installed using a combination of suspension and bottom support. This involves hoisting the glass to a predetermined position using hoisting equipment and connecting it to the building structure using clamps or other suspension components. Simultaneously, the bottom edge of the glass rests in a pre-designed groove in the building structure, with rigid pads placed at the bottom of the groove for support and positioning. However, existing clamps often use fixed angles or fixed clamping surfaces, making it difficult to fully conform to the curved surface of the glass. This can easily lead to localized contact, concentrating the hoisting load in specific areas and causing stress concentration. Furthermore, clamps usually rely on manual tightening, resulting in inconsistent tightening force and potential safety hazards due to incomplete tightening. In addition, the rigid support formed by the groove and rigid pads at the bottom of the glass restricts vertical displacement under its own weight and temperature changes, easily generating additional stress. This method also requires high precision in matching the groove elevation, pad height, and glass cutting dimensions; dimensional deviations can easily lead to localized suspension or compression of the glass, resulting in uneven stress and stress concentration. Summary of the Invention
[0004] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the present invention aims to provide a hoisting device and method for curved glass curtain walls, enabling the hoisting clamps to adaptively adjust their clamping posture according to the curved shape of the glass curtain wall, ensuring a close fit with the glass surface. This reduces the risk of stress concentration caused by concentrated hoisting loads in localized areas of the glass and effectively improves the consistency of locking force. The bottom support component can adapt to the vertical deformation of the glass under its own weight and temperature changes, and effectively regulate the reaction force at each support point, improving the support stress state at the bottom of the glass, reducing additional stress, and enhancing the adaptability and matching accuracy of the hoisting device for curved glass curtain walls of different sizes and curvatures.

[0012] In some alternative embodiments, the width of the bottom groove is greater than the thickness of the curved glass panel, the inner wall of the bottom groove is provided with an elastic pad, and the bottom groove is used to restrict the displacement of the curved glass panel in the out-of-plane direction and allow the curved glass panel to move in the vertical direction; and / or, The top surface of the support plate is provided with a U-shaped groove for accommodating the bottom edge of the curved glass panel.

[0014] The method for hoisting curved glass curtain walls, using the aforementioned curved glass curtain wall hoisting device, includes the following steps: S1: Obtain the specifications of the curved glass panel, perform a stress analysis on the curved glass panel based on the specifications, and determine the target total stiffness and target compression displacement of the bottom support required for the curved glass panel; determine the target stiffness and specifications of each elastic element based on the target total stiffness of the spring, and preset the preset compression displacement range of the elastic element, the contact conditions of the clamping assembly, the posture stability conditions, and the preset locking torque of the electronically controlled locking assembly; determine the preset installation height of the clamping assembly based on the height dimension and installation elevation of the curved glass panel. S2: Install the clamping mechanism at a predetermined installation position on the main building structure. According to the preset installation height, adjust the vertical position of the clamping assembly through the suspension assembly so that the clamping assembly is at the preset installation height. At the same time, control the universal ball joint assembly to be in the released state so that the clamping assembly can rotate freely relative to the suspension assembly. S3: Install the elastic elements that match the target stiffness into the corresponding elastic support assemblies; arrange multiple elastic support assemblies sequentially along the arc direction of the curved glass panel into the bottom grooves embedded in the main building structure; adjust the support plates of the corresponding elastic support assemblies to the initial height using multiple height adjustment elements, and zero the corresponding displacement indicators; S4: Using a lifting device, the curved glass panel is lifted to the predetermined installation position, aligning the bottom edge of the curved glass panel with the bottom groove and slowly lowering it so that the bottom edge of the curved glass panel sits on multiple support plates; gradually unloading the lifting force applied to the curved glass panel by the lifting device, so that the self-weight of the curved glass panel is gradually borne by multiple elastic support assemblies, and causing the elastic elements to undergo elastic compression; S5: Pre-clamp the clamping assembly located at the top of the curved glass panel with the curved glass panel, and keep the universal ball joint assembly in the released state, so as to allow the clamping assembly to rotate relative to the suspension assembly under the action of the curved glass panel, so that the clamping surface of the clamping assembly is adaptively adjusted to a clamping posture that matches the local surface of the corresponding area at the top of the curved glass panel. S6: The intelligent sensing component collects the contact pressure distribution information between the clamping component and the curved glass panel, as well as the posture information of the clamping component. Based on the contact pressure distribution information, the component determines the bonding state between the clamping component and the curved glass panel, and based on the posture information, the component determines the posture stability state of the clamping component. S7: When the fitting state meets the preset fitting conditions and the posture of the clamping assembly meets the preset posture stability conditions, a preset locking torque is applied to the clamping assembly to establish a reliable clamping connection between the clamping assembly and the curved glass panel; and the electronically controlled locking assembly is controlled to lock the universal ball joint assembly to maintain the adaptive clamping posture of the clamping assembly relative to the suspension assembly. S8: After the universal ball joint assembly is locked, the compression displacement of the elastic element indicated by the displacement indicator of the multiple elastic support assemblies is obtained respectively, and each compression displacement is compared with the preset compression displacement range; when any compression displacement exceeds the preset compression displacement range, the height of the corresponding elastic support assembly is adjusted by the corresponding height adjustment component to change the compression displacement of the corresponding elastic element so that the compression displacement is within the preset compression displacement range; S9: Reacquire the compression displacement of the elastic element of the multiple elastic support assemblies, and repeat step S8 until the compression displacement of the elastic element corresponding to the multiple elastic support assemblies is within the preset compression displacement range. S10: Obtain the node identifier of the clamping mechanism, the fitting status of the clamping assembly, the locking torque, the clamping posture information, the compression displacement of each elastic element, and the installation time information, and store the obtained data in association to form a digital installation quality record corresponding to the curved glass panel.
[0015] The beneficial effects of this invention are: This invention provides a hoisting device and method for curved glass curtain walls. Through the coordinated operation of a clamping mechanism and a bottom support mechanism, the clamping mechanism utilizes a universal ball joint assembly to allow the clamping assembly to rotate in multiple directions relative to the suspension assembly, thereby adapting to the curved surface posture of the top of the curved glass panel. An intelligent sensing component detects the contact state and clamping posture between the clamping assembly and the glass. After meeting preset conditions, an electronically controlled locking component locks the universal ball joint assembly, maintaining a stable clamping posture and reducing the risk of clamping misalignment and localized stress concentration. Simultaneously, the bottom support mechanism, along the glass... Multiple elastic support components and corresponding height adjustment devices are independently set along the curved direction of the glass, allowing each support position to be adjusted to match the height of the bottom edge of the glass. The elastic components buffer and provide elastic support for vertical displacement and load changes during the glass placement process. The displacement indicator monitors the compression displacement of each support position to determine the support status and assist in adjustment. This ensures that the curved glass panel receives more uniform and stable support during hoisting and placement, reducing local suspension, excessive top pressure and impact stress, and improving the stability and safety of the curved glass curtain wall hoisting and installation.

[0025] Example 1 Please refer to Figures 1 to 3This embodiment provides a hoisting device for an arc-shaped glass curtain wall, including a clamping mechanism and a bottom support mechanism. The clamping mechanism includes a suspension assembly 1, a universal ball joint assembly 2, a clamping assembly 3, an intelligent sensing assembly 4, and an electrically controlled locking assembly 5. The suspension assembly 1 is adjustable vertically, and the clamping assembly 3 is used to clamp the top of the arc-shaped glass panel 100. The universal ball joint assembly 2 is located between the suspension assembly 1 and the clamping assembly 3, allowing the clamping assembly 3 to rotate in multiple directions relative to the suspension assembly 1 to adjust its clamping posture. The intelligent sensing assembly 4 is located on the clamping assembly 3 and is used to detect the contact state between the clamping assembly 3 and the arc-shaped glass panel 100, as well as the clamping posture information of the clamping assembly 3, and outputs the corresponding detection results. The electrically controlled locking assembly 5 is connected to the universal ball joint assembly 2 and can lock or release the universal ball joint assembly 2 according to the detection results of the intelligent sensing assembly 4. The bottom support mechanism... The structure includes a bottom groove 6, multiple elastic support assemblies 7, and multiple height adjustment components 8. The bottom groove 6 is embedded in the main building structure. The multiple elastic support assemblies 7 are sequentially arranged in the bottom groove 6 along the arc direction of the curved glass panel 100. The multiple height adjustment components 8 are arranged in the bottom groove 6 and are respectively arranged at the bottom of the multiple elastic support assemblies 7, for independently adjusting the initial height of each elastic support assembly 7. Each elastic support assembly 7 includes a support plate 71, at least one elastic element 72, and a displacement indicator. The elastic element 72 is arranged above the height adjustment component 8, and the support plate 71 is arranged above the elastic element 72, for supporting the bottom edge of the curved glass panel 100. The elastic element 72 can elastically deform with the vertical displacement of the curved glass panel 100 to provide elastic support force for the curved glass panel 100. The displacement indicator is used to indicate the compression displacement of the corresponding elastic element 72 to characterize the support state of each elastic element 72.
[0026] Through the coordinated operation of the clamping mechanism and the bottom support mechanism, the clamping mechanism utilizes the universal ball joint assembly 2 to enable the clamping assembly 3 to rotate in multiple directions relative to the suspension assembly 1, thereby adapting to the curved surface posture of the top of the curved glass panel 100. The intelligent sensing assembly 4 detects the contact state and clamping posture between the clamping assembly 3 and the glass. After meeting preset conditions, the electronically controlled locking assembly 5 locks the universal ball joint assembly 2, maintaining a stable clamping posture and reducing the risk of clamping misalignment and localized force concentration. Simultaneously, the bottom support mechanism, independently set along the curved direction of the glass... Multiple elastic support components 7 and corresponding height adjustment components 8 enable each support position to be adjusted to a height that matches the bottom edge of the glass. The elastic components 72 buffer and provide elastic support for vertical displacement and load changes during the glass placement process. The displacement indicator monitors the compression displacement of each support position to determine the support status and assist in adjustment. This ensures that the curved glass panel 100 receives more uniform and stable support during hoisting and placement, reducing local suspension, excessive top pressure and impact stress, and improving the stability and safety of the curved glass curtain wall hoisting and installation.
[0027] In some embodiments, the suspension assembly 1 includes a base plate 11 and a vertical adjustment screw 12. The base plate 11 is fixedly connected to the main building structure. The vertical adjustment screw 12 is disposed on the base plate 11 in a vertical direction and is threadedly engaged with the base plate 11. The bottom end of the vertical adjustment screw 12 is connected to the universal ball joint assembly 2. By rotating the vertical adjustment screw 12, the vertical adjustment screw 12 is raised and lowered relative to the base plate 11 in a vertical direction to adjust the vertical position of the clamp assembly 3.
[0028] In some embodiments, the universal ball joint assembly 2 includes a ball socket base 21, a ball head screw 22, and a locking nut 23. The ball socket base 21 is connected to the suspension assembly 1 and has a spherical receiving cavity with an opening at the bottom. The ball head of the ball head screw 22 is received in the spherical receiving cavity and can rotate in multiple directions relative to the ball socket base 21. The screw portion of the ball head screw 22 protrudes through the opening and is connected to the clamp assembly 3. The locking nut 23 is sleeved on the screw portion of the ball head screw 22 and threadedly connected to the screw portion. It is located on the outer side of the lower end face of the ball socket base 21. The electrically controlled locking assembly 5 is connected to the locking nut 23 and can drive the locking nut 23 to move along the screw portion to lock or release the rotation of the ball head screw 22 relative to the ball socket base 21. The ball head of the ball screw 22 can rotate in multiple directions within the spherical cavity, allowing the clamping assembly 3 connected to the ball screw 22 to adaptively adjust according to the actual curved surface posture of the top of the curved glass panel 100. This prevents misalignment between the clamp and the glass due to changes in the curvature of the curved glass or deviations in the lifting position. Simultaneously, by providing a locking nut 23 threadedly engaged with the ball screw 22 and driven by the electrically controlled locking assembly 5, the rotation of the ball screw 22 relative to the ball socket base 21 is restricted after the clamp is adjusted to a suitable clamping posture, thus reliably maintaining the adjusted clamping posture. When readjustment is required, the ball screw 22 can be released, restoring the clamp to an adjustable state. This enables the lifting clamping mechanism to have both multi-directional attitude self-adaptation capability and adjusted attitude locking capability, which facilitates the clamping and alignment of the curved glass panel 100, avoids unexpected changes in the clamping attitude during the lifting process, reduces repeated manual adjustments and locking operations, improves the clamping efficiency and stability of the curved glass panel 100, and reduces the risk of abnormal glass stress caused by changes in clamping attitude during the lifting process.
[0029] In some embodiments, the clamping assembly 3 includes two clamping plates 31, a connector 32, a fastening bolt 33, and a flexible pad 34; the two clamping plates 31 are arranged opposite to each other for clamping the top of the curved glass panel 100; the connector 32 is connected to the two clamping plates 31 respectively and is fixedly connected to the universal ball joint assembly 2; the top of the curved glass panel 100 is provided with a threaded hole, and the fastening bolt 33 is respectively threaded through the clamping plates 31 on both sides of the curved glass panel 100 and threadedly engaged with the threaded hole of the curved glass panel 100 to adjust the tightness of the clamping of the curved glass panel 100 by the two clamping plates 31; the flexible pad 34 is disposed on the side of the clamping plate 31 facing the curved glass panel 100 for contacting the curved glass panel 100. The top of the curved glass panel 100 is clamped by two clamping plates 31 and fastening bolts 33, and mechanical limiting is formed by the mounting holes, which improves the connection reliability between the curved glass panel 100 and the clamping assembly 3. At the same time, the clamping force is controlled by adjusting the fastening bolts 33, and a flexible pad 34 is set between the clamping plates 31 and the glass to adapt to the curved surface of the glass, buffer and disperse the clamping force, and reduce the risk of local stress concentration and glass damage. In addition, the connector 32 connects the clamping assembly 3 to the universal ball joint assembly 2, so that the clamping assembly 3 can adjust the clamping posture with the universal ball joint, thereby improving the adaptability to the curved surface of the curved glass panel 100 and the stability and safety during the hoisting process.
[0030] The flexible pad 34 can be a silicone pad, and no specific limitation is made here.
[0031] Specifically, the connector 32 can be a U-shaped connector frame, which includes two oppositely arranged side connectors and a top connector connected between the two side connectors. The two side connectors are respectively connected to the two clamping plates 31, and the top connector is connected to the universal ball joint assembly 2, so that the two clamping plates 31 form an integrated clamping structure through the U-shaped connector frame, and can stably transfer the clamping load to the universal ball joint assembly 2. At the same time, the U-shaped connector frame has good structural rigidity and load-bearing capacity, which is conducive to improving the overall stability of the clamping assembly 3 during the hoisting process.
[0032] In some embodiments, the intelligent sensing component 4 includes a pressure detection element, an attitude detection element 41, and a data processing control unit. The pressure detection elements are arranged in a matrix and embedded on the side of the flexible pad 34 facing the curved glass panel 100, for real-time detection of the contact pressure and its distribution between the two clamping plates 31 and the curved glass panel 100. The attitude detection element 41 is disposed on the screw portion of the clamping assembly 3 or the ball head screw 22, for real-time detection of the spatial attitude and angular velocity of the clamping assembly 3. The data processing control unit is communicatively connected to the pressure detection element, the attitude detection element 41, and the electronically controlled locking assembly 5, for receiving and processing the detection data output by the pressure detection element and the attitude detection element 41, and generating locking control commands according to the processing results to control the electronically controlled locking assembly 5 to lock or release the universal ball joint assembly 2. By embedding pressure sensors in a matrix within the flexible pad 34, contact pressure information of different areas between the clamping plate 31 and the curved glass panel 100 can be acquired, and corresponding pressure distribution data can be generated. This allows for the determination of the fit and stress uniformity of the clamping area, and the identification of areas with concentrated local pressure. Simultaneously, the embedding of the pressure sensors within the flexible pad 34 prevents them from protruding from the surface of the pad 34 and forming localized hard contact points. This ensures the flexible pad 34 maintains a continuous flexible contact state, protecting the pressure sensors while adapting to the curved surface of the curved glass panel 100, and reducing the risk of glass damage caused by localized stress concentration. By setting up an attitude detection device 41 to acquire the spatial attitude and angular velocity of the clamping assembly 3 in real time, the attitude changes and rotation state of the clamping assembly 3 can be determined, providing a basis for adjusting the clamping attitude and determining the locking timing. Furthermore, the data processing and control unit comprehensively processes the pressure detection data and attitude detection data, and controls the electronic locking component 5 to lock or release the universal ball joint component 2 according to the processing results. This allows the component to lock the current clamping attitude when the pressure distribution meets the preset conditions and the attitude change tends to be stable, and to maintain or restore the adjustable state when the clamping state or attitude does not meet the preset conditions. This enables the clamping component 3 to sense, adjust, confirm and lock, reducing manual judgment and repeated adjustments, and improving the clamping stability and hoisting safety of the curved glass panel 100.
[0033] Specifically, the pressure detection element can be a matrix-type flexible thin-film pressure sensor. Multiple pressure detection units are distributed according to a preset array and set on the side of the flexible pad 34 facing the curved glass panel 100 to detect the contact pressure in different areas between the clamping plate 31 and the curved glass panel 100 in real time, thereby obtaining the corresponding contact pressure distribution data.
[0034] The attitude detection component 41 can be equipped with a triaxial accelerometer and a gyroscope module to acquire acceleration information of the clamping assembly 3 in different directions and angular velocity information about the corresponding axis. By combining the acceleration and angular velocity information, the spatial attitude and attitude change state of the clamping assembly 3 can be determined more accurately, and the rotation of the clamping assembly 3 during hoisting and attitude adjustment can be identified. This reduces the possibility of misjudgment caused by hoisting vibration and dynamic acceleration interference of a single attitude detection parameter, and provides a reliable basis for judging whether the clamping assembly 3 has reached the preset clamping attitude and whether it is in a stable state, thereby facilitating the determination of the locking timing of the universal ball joint assembly 2.
[0035] The data processing and control unit includes a microcontroller, a signal conditioning circuit, an analog-to-digital converter, and a low-power Bluetooth wireless communication module. The signal conditioning circuit is electrically connected to the pressure detection element and the attitude detection element 41, and is used to amplify, filter, and denoise the detection signals output by the pressure detection element and the attitude detection element 41. The analog-to-digital converter is used to convert the conditioned analog detection signal into a digital signal. The microcontroller is used to process the digital signal to obtain the clamping pressure distribution of the curved glass panel 100 and the attitude change state of the clamping assembly 3, and to generate corresponding locking control commands according to preset clamping state criteria and attitude stability criteria. The low-power Bluetooth wireless communication module is used to realize data interaction between the data processing and control unit and an external control terminal to transmit detection data and locking state information, and to receive external control commands.
[0036] In some embodiments, the intelligent sensing component 4 further includes a waterproof control box 42, which is fixedly disposed on one side of the clamping component 3. The data processing control unit is disposed inside the waterproof control box 42 to provide waterproof protection for the data processing control unit. The waterproof control box 42 may employ a housing with a sealed structure to enclose and protect the data processing control unit, reducing the possibility of external factors such as rainwater, construction water, moisture, and dust entering the data processing control unit. This lowers the risk of electronic components becoming damp, short-circuited, or experiencing abnormal detection signals, improving the operational reliability of the intelligent sensing component 4 in hoisting construction environments, thereby ensuring the stable operation of pressure detection, attitude detection, and electronic locking control.
[0037] In some embodiments, the intelligent sensing component 4 further includes a handheld terminal, which is communicatively connected to the data processing control unit. The handheld terminal receives and displays the detection data processed by the data processing control unit and sends manual control commands to the data processing control unit to control the electronic locking component 5 to lock or release the universal ball joint component 2. By setting up the handheld terminal, construction personnel can view and intuitively grasp the detection data acquired by the pressure detection component and the attitude detection component 41, as well as the locking status of the universal ball joint component 2, in real time. Simultaneously, construction personnel can send manual control commands to the data processing control unit through the handheld terminal according to the on-site hoisting conditions. This allows them to actively control the universal ball joint component 2 to lock after the clamping component 3 reaches a suitable clamping posture, or to control the universal ball joint component 2 to release and readjust its posture when an abnormal clamping state is detected. Thus, by adding manual verification and intervention functions to the automatic sensing and automatic control, the flexibility and reliability of clamp posture control during hoisting are improved, and construction personnel can control the clamp locking status from a relatively safe distance.
[0038] Specifically, the handheld terminal includes a touch screen, which is used to display contact pressure distribution data processed by the data processing control unit, attitude data of the clamp assembly 3, and locking status of the universal ball joint assembly 2. It is also used to receive locking and releasing commands input by the construction personnel, so as to control the electronic locking assembly 5 to lock or release the universal ball joint assembly 2 through the data processing control unit.
[0039] In some optional embodiments, the electrically controlled locking assembly 5 includes an electric torque sleeve 51 and a drive motor 52. The electric torque sleeve 51 is sleeved on the outside of the locking nut 23 and connected to the locking nut 23. The output end of the drive motor 52 is connected to the electric torque sleeve 51 and communicates with the intelligent sensing assembly 4. It is used to drive the electric torque sleeve 51 to rotate the locking nut 23 relative to the ball head screw 22 according to the control command output by the intelligent sensing assembly 4. By setting up an electric torque sleeve 51 and a drive motor 52, the locking nut 23 can be automatically driven to lock or release according to the control commands output by the intelligent sensing component 4, eliminating the need for manual operation of the locking nut 23 by construction personnel. This achieves automated control of the locking and releasing process of the universal ball joint assembly 2. At the same time, the electric torque sleeve 51 can apply a preset torque to the locking nut 23, which helps to control the degree of force applied during the locking process, so that different locking operations have a more consistent locking effect. This reduces the situation of insufficient or excessive locking caused by inconsistent manual locking force, and improves the stability and reliability of the locking state of the universal ball joint assembly 2.
[0040] In some embodiments, the width of the bottom groove 6 is greater than the thickness of the curved glass panel 100, the inner wall of the bottom groove 6 is provided with an elastic pad, the bottom groove 6 is used to limit the displacement of the curved glass panel 100 in the out-of-plane direction and allow the curved glass panel 100 to move in the vertical direction; and / or, the top surface of the support plate 71 is provided with a U-shaped groove for accommodating the bottom edge of the curved glass panel 100, the inner wall of the U-shaped groove is provided with an elastic pad to elastically support the bottom edge of the curved glass panel 100. By setting the width of the bottom groove 6 to be greater than the thickness of the curved glass panel 100, and providing an elastic pad on the inner wall of the bottom groove 6, a flexible limiting structure with a certain amount of room for movement is formed between the curved glass panel 100 and the bottom groove 6. This restricts the curved glass panel 100 from swaying in the out-of-plane direction while avoiding rigid constraints on the vertical displacement of the curved glass panel 100. This allows the curved glass panel 100 to be vertically adjusted according to the compression deformation of the elastic support assembly 7, reducing the additional stress and local squeezing risk caused by the rigid clamping of the bottom groove 6. At the same time, the elastic pad can buffer the contact force between the curved glass panel 100 and the bottom groove 6, reducing the risk of damage to the glass edge due to rigid collision or local squeezing. By setting a U-shaped groove, the bottom edge of the curved glass panel 100 can be accommodated and laterally limited, allowing the curved glass panel 100 to sit stably on the support plate 71, reducing the possibility of lateral displacement or slippage of the bottom edge of the glass during the support process. At the same time, by setting an elastic pad in the U-shaped groove, a flexible contact is formed between the bottom edge of the curved glass panel 100 and the support plate 71, which can buffer the glass's own weight and the impact load generated during the hoisting and placement process, and disperse the supporting force to a certain extent in the bottom edge area of the glass, thereby reducing the risk of glass edge breakage or stress concentration due to local hard contact, and improving the stability of the curved glass panel 100 during placement and installation.
[0041] Specifically, silicone pads can be used for the elastic pads, and no specific limitation is made here.
[0042] The height adjustment component 8 includes an adjusting screw and a lifting support base. The adjusting screw is vertically positioned within the bottom slot 6 and threaded into it. The lifting support base is connected to the adjusting screw, and an elastic element 72 is positioned above the lifting support base. The lifting support can move vertically as the adjusting screw rotates to adjust the initial height of the elastic support assembly 7. The adjustment method, using a threaded engagement between the adjusting screw and the bottom slot 6, converts the rotational motion of the adjusting screw into the vertical displacement of the lifting support base, and allows for precise adjustment of the height of the lifting support base by controlling the amount of rotation of the adjusting screw.
[0043] Example 2 This embodiment provides a method for hoisting an arc-shaped glass curtain wall, using the arc-shaped glass curtain wall hoisting device from Embodiment 1, and includes the following steps: S1: Obtain the specifications of the curved glass panel 100, perform a stress analysis on the curved glass panel 100 based on the specifications, and determine the target total stiffness and target compression displacement of the bottom support required for the curved glass panel 100; determine the target stiffness and specifications of each elastic element 72 based on the target total stiffness of the spring, and preset the preset compression displacement range of the elastic element 72, the contact conditions of the clamping assembly 3, the posture stability conditions, and the preset locking torque of the electrically controlled locking assembly 5; determine the preset installation height of the clamping assembly 3 based on the height dimension and installation elevation of the curved glass panel 100. S2: Install the clamping mechanism at the predetermined installation position on the main structure of the building. According to the preset installation height, adjust the vertical position of the clamping assembly 3 through the suspension assembly 1 so that the clamping assembly 3 is at the preset installation height; at the same time, control the universal ball joint assembly 2 to be in the released state so that the clamping assembly 3 can rotate freely relative to the suspension assembly 1. S3: Install the elastic element 72 that matches the target stiffness into the corresponding elastic support assembly 7; arrange multiple elastic support assemblies 7 in sequence along the arc direction of the curved glass panel 100 into the bottom groove 6 embedded in the main building structure; adjust the support plate 71 of the corresponding elastic support assembly 7 to the initial height through multiple height adjustment elements 8, and zero the corresponding displacement indicator. S4: Using a lifting device, the curved glass panel 100 is lifted to the predetermined installation position, the bottom edge of the curved glass panel 100 is aligned with the bottom groove 6 and slowly lowered, so that the bottom edge of the curved glass panel 100 sits on multiple support plates 71; the lifting force applied to the curved glass panel 100 by the lifting device is gradually unloaded, so that the weight of the curved glass panel 100 is gradually borne by multiple elastic support assemblies 7, and the elastic members 72 are elastically compressed. S5: Pre-clamp the clamping assembly 3 located at the top of the curved glass panel 100 with the curved glass panel 100, and keep the universal ball joint assembly 2 in the released state, so that the clamping assembly 3 can rotate relative to the suspension assembly 1 under the action of the curved glass panel 100, so that the clamping surface of the clamping assembly 3 can be adaptively adjusted to match the local surface of the corresponding area at the top of the curved glass panel 100. S6: The intelligent sensing component 4 collects the contact pressure distribution information between the clamp component 3 and the curved glass panel 100, as well as the posture information of the clamp component 3. Based on the contact pressure distribution information, the clamp component 3 and the curved glass panel 100 are judged to be in contact, and based on the posture information, the posture stability of the clamp component 3 is judged. S7: When the fitting state meets the preset fitting conditions and the posture of the clamping assembly 3 meets the preset posture stability conditions, a preset locking torque is applied to the clamping assembly 3 to establish a reliable clamping connection between the clamping assembly 3 and the curved glass panel 100; and the electronic locking assembly 5 is controlled to lock the universal ball joint assembly 2 to maintain the adaptive clamping posture of the clamping assembly 3 relative to the suspension assembly 1. S8: After the universal ball joint assembly 2 is locked, the compression displacement of the elastic element 72 indicated by the displacement indicators of the multiple elastic support assemblies 7 is obtained respectively, and each compression displacement is compared with the preset compression displacement range; when any compression displacement exceeds the preset compression displacement range, the height of the corresponding elastic support assembly 7 is adjusted by the corresponding height adjustment component 8 to change the compression displacement of the corresponding elastic element 72 so that the compression displacement is within the preset compression displacement range. S9: Reacquire the compression displacement of the elastic element 72 of the multiple elastic support assemblies 7, and repeat step S8 until the compression displacement of the elastic element 72 corresponding to the multiple elastic support assemblies 7 is within the preset compression displacement range. S10: Obtain the node identifier of the clamping mechanism, the contact status of the clamping component 3, the locking torque, the clamping posture information, the compression displacement of each elastic element 72, and the installation time information, and store the obtained data in association to form a digital installation quality record of the corresponding curved glass panel 100.
[0044] Before hoisting, a stress analysis is performed based on the specifications of the curved glass panel 100 to determine the bottom elastic support parameters, clamp installation height, and locking parameters. During hoisting, the rotatable universal ball joint assembly 2 allows the clamp assembly 3 to adaptively adjust its posture according to the glass curvature. The clamp's contact and stability are determined by combining contact pressure distribution and clamp posture information. Once preset conditions are met, the clamp is automatically locked. Simultaneously, after the glass is positioned, multiple independently adjustable elastic support assemblies 7 provide elastic support to the bottom of the glass, and the corresponding supports are adjusted according to the actual compression displacement of each elastic element 72. The system allows for independent adjustment of each support point, ensuring that the load-bearing capacity of each support point is within a reasonable range. This enables coordinated adjustment of the clamping posture, clamping force, and bottom support status during the hoisting of the curved glass panel 100, reducing the risk of glass damage caused by insufficient surface adaptation, localized stress concentration, or uneven support, and improving the stability and safety of the curved glass curtain wall hoisting and installation process. Furthermore, by associating and storing information such as clamping status, locking torque, clamp posture, elastic element 72 compression displacement, and installation time, a digital installation quality record for the corresponding glass panel is formed, enabling traceable management of the installation process.
[0045] Specifically, in order to determine the target total spring stiffness and target compression displacement in step S1, this embodiment adopts a simplified calculation method for the statically indeterminate curved glass panel 100 with two-point bolt hinges at the top and multiple spring elastic supports at the bottom.
[0046] Since the curved glass panel 100 is simultaneously subjected to vertical self-weight and out-of-plane wind load, this embodiment decomposes the spatial stress of the curved glass panel 100 into in-plane stress and out-of-plane stress, calculates them separately, and finally superimposes the stresses obtained under different stress states and performs strength verification.
[0047] I. Parameter Definition The specifications of the curved glass panel 100 include glass height H, glass arc length S, glass chord length L, and glass arc sag f. The parameters are: glass arc radius R, glass thickness t, suspension bolt hole diameter d, hole end distance B (B≥2d), and the number n of elastic support components 7. The stiffness of the i-th elastic element 72 is denoted as K. i The equivalent total stiffness of the multiple elastic elements 72 is denoted as K. 总 Let E be the elastic modulus of the glass, A be the cross-sectional area of the glass, and determine the cross-sectional area of the glass (A=St) based on the glass arc length S and glass thickness t. The self-weight linear load of the glass is q. G ( The standard value of wind load is q. W Design value of compressive strength f of glass hole wall g承压 Design value of glass edge strength f g边 and the design value f of the strength in the middle of the glass g These are the corresponding strength design parameters.
[0048] When selecting a spring, the equivalent total stiffness of multiple elastic elements 72 satisfies: K 总 =K1 + K2 + ... + K n ; Among them, K 总 Used to characterize the overall elastic support capability of multiple bottom elastic support components 7 in the vertical direction.
[0049] II. Establish an in-plane equivalent force model and solve for the total reaction force of the bottom spring. First, the curved glass panel 100 is simplified in the in-plane direction as a force model with two hinged points at the top and an equivalent spring supporting the bottom, where the stiffness of the equivalent spring is taken as K. 总 The calculated height of the curved glass panel 100 is taken as H.
[0050] To solve for the support reaction force of the bottom spring using the force method, the equivalent bottom spring is removed from the force model, and the unknown total reaction force R acting on the bottom of the curved glass panel 100 is used. bThe support function of the equivalent spring at the bottom is replaced, thereby establishing a basically statically determinate structure. Wherein, R... b Let be the total reaction force of the bottom spring to be determined.
[0051] Based on the force method, establish the bottom displacement compatibility equation to ensure that the basic statically determinate structure is subjected to its own weight and the unknown total reaction force R at the bottom. b The vertical displacement at the bottom caused by the action is coordinated with the compression deformation of the equivalent spring.
[0052] Among them, the bottom vertical displacement of a statically determinate structure under a unit vertical force corresponds to the unit load compliance coefficient; the statically determinate structure under the glass self-weight linear load q G The vertical displacement at the bottom generated by the action is determined according to the axial tension-compression deformation relationship in mechanics of materials.
[0053] Substituting the displacement parameters above into the force method equation, the total reaction force R of the bottom spring can be obtained. b Furthermore, based on Hooke's Law, the theoretical compression displacement Δy corresponding to the equivalent spring is determined.
[0054] The calculation process is used to determine the current total spring stiffness K. 总 Under these conditions, the vertical load shared by the bottom elastic support and the corresponding elastic compression state.
[0055] III. Calculation of reaction force at the top suspension point and in-plane forces Based on the total reaction force R of the bottom spring b And the self-weight load borne by the curved glass panel 100, and calculate the vertical reaction force borne by the two top suspension points respectively.
[0056] Furthermore, taking the top of the curved glass panel 100 as the starting point, for any height section at a distance y from the top, the axial force at that section is determined based on the load and support reaction above that section.
[0057] Since the curved glass panel 100 has an initial curvature, when the curved glass panel 100 is subjected to axial pressure, the axial force is coupled with the initial curvature of the glass, forming an additional in-plane bending moment inside the glass panel.
[0058] Therefore, based on the initial curvature parameters f and R of the curved glass panel 100 and the axial force at the corresponding height position, the in-plane additional bending moment generated by the coupling of the axial force and the initial curvature is calculated, and the in-plane force state at different height positions of the curved glass panel 100 is obtained accordingly.
[0059] IV. Calculate the out-of-plane forces on the curved glass panel 100. For the wind load on the curved glass panel 100, its out-of-plane stress is simplified to the stress problem of a simply supported rectangular plate under uniformly distributed wind load.
[0060] According to the standard value of wind load q W The out-of-plane bending moment is calculated based on the geometric dimensions of the curved glass panel 100, and the maximum out-of-plane bending moment of the curved glass panel 100 is determined.
[0061] Based on the overall stress state of the curved glass panel 100 under wind load, the out-of-plane reaction forces borne by the two top suspension points are determined.
[0062] This provides the calculation basis for the force components of the top lifting point in the vertical and out-of-plane directions, which is used to calculate the resultant force of the lifting point bolts and check the strength of the lifting point area.
[0063] V. Strength verification of suspension points and glass body Calculate the resultant force borne by the bolts at the corresponding lifting points based on the vertical and out-of-plane reactions borne by the two top lifting points respectively.
[0064] The bearing stress of the bolt hole wall is calculated based on the resultant force of the bolts at the lifting points, and the bearing stress of the hole wall is compared with the design value of the bearing strength of the glass hole wall to determine whether the bolt hole wall at the lifting points meets the strength requirements.
[0065] Furthermore, circumferential tensile stress is calculated for the area around the bolt holes of the lifting points, and the stress concentration effect caused by the bolt holes of the lifting points on the local stress on the glass is considered. The stress concentration factor K is taken according to the design value, and in this embodiment, K=3.0.
[0066] The calculated circumferential tensile stress at the hole edge is compared with the design value of the glass edge strength to determine whether the area at the hole edge of the suspension point meets the strength requirements.
[0067] For the central region of the curved glass panel 100, the out-of-plane bending stress is calculated based on the out-of-plane bending moment generated by the wind load, and compared with the strength design value of the central region of the glass.
[0068] For the bottom region of the curved glass panel 100, since the bottom is simultaneously subjected to axial pressure and in-plane bending caused by the coupling of initial curvature and axial force, the axial compressive stress and in-plane bending compressive stress of the bottom section are calculated separately and then superimposed to obtain the total compressive stress of the bottom section.
[0069] Finally, the strength of the lifting point hole edge area, non-hole edge area, and bottom area are checked separately. When the calculated stress in the corresponding area does not exceed the corresponding strength design value, the current total spring stiffness K is determined. 总 It meets the strength requirements.
[0070] VI. Iterative Determination of the Total Stiffness of the Target Spring Due to the total stiffness K of the bottom spring 总This will affect the vertical load borne by the bottom spring and the load borne by the top suspension point. Therefore, in this embodiment, the total stiffness of the target spring is determined by an iterative method.
[0071] First, a set of initial total spring stiffness K is given. 总 Then, substituting the initial total spring stiffness into the force method equation, the corresponding total bottom spring reaction force R is obtained. b .
[0072] Based on the total reaction force R of the bottom spring b Further calculate the vertical reaction forces at the two top suspension points, and calculate the bearing stress of the bolt hole wall, the circumferential tensile stress at the hole edge, the total compressive stress at the bottom of the curved glass panel 100, and the out-of-plane bending stress.
[0073] Compare the calculated stresses with their corresponding strength design values.
[0074] When the stress on the lifting point or the stress in the area around the lifting point hole exceeds the corresponding allowable value, increase the total spring stiffness K. 总 This allows the bottom elastic support to bear more vertical load, thereby reducing the load borne by the top suspension point; after adjusting the total stiffness of the spring, the force method equation is resubmitted and the above calculation is performed.
[0075] When the force or stress on the bottom area exceeds the corresponding allowable value, reduce the total spring stiffness K. 总 This allows the top suspension point to bear more vertical load, thereby reducing the load shared by the bottom elastic support; the above calculations are then performed again after the adjustment.
[0076] Repeat the above iterative process until all calculated stresses in the hanging point region, bottom region, and middle region of the glass meet the corresponding strength conditions.
[0077] Among multiple total spring stiffnesses that satisfy various strength conditions, the total spring stiffness within a preset proportion range that makes the calculated stress in the main stress-bearing area close to the corresponding strength design value is further selected as the target total spring stiffness. In this embodiment, the preset proportion range can be taken as 80% to 95% of the corresponding strength design value.
[0078] This achieves a reasonable load distribution between the load-bearing capacity of the top suspension point and the load-bearing capacity of the bottom elastic support, and avoids situations where the top suspension point is subjected to excessive force due to insufficient total spring stiffness, or where the bottom support area is subjected to excessive force due to excessive total spring stiffness.
[0079] 7. Determine the specifications of each elastic element based on the total stiffness of the target spring. After determining the target total stiffness of the spring, the elastic elements 72 in the spring library are combined according to their specifications so that the equivalent total stiffness of the multiple elastic elements 72 reaches the target total stiffness of the spring.
[0080] Specifically, according to: K 总 =K1 + K2 + ... + K n Select the corresponding number of elastic elements 72.
[0081] Multiple elastic elements 72 can be of the same specification, or different specifications of elastic elements 72 can be combined according to the load-bearing requirements of different locations.
[0082] When using elastic elements 72 of the same specification, each elastic element 72 has the same target stiffness; when using a combination of elastic elements 72 of different specifications, the stiffness of the corresponding elastic element 72 is determined according to the design support reaction force corresponding to each elastic support assembly 7, so that the equivalent total stiffness of the combination of multiple elastic elements 72 meets the target total stiffness requirement of the spring.
[0083] VIII. Determination of Target Compression Displacement Determine the total stiffness K of the target spring. 总 and the total reaction force R of the bottom spring b Then, the theoretical compression displacement of the elastic element 72 is determined based on the stiffness of the elastic element 72 and the corresponding support reaction force.
[0084] When multiple elastic elements 72 adopt the same specifications, the target stiffness of each elastic element 72 is determined according to the total stiffness of the target spring, and the theoretical compression displacement of each elastic element 72 is determined according to the theoretical support reaction force corresponding to each elastic element 72.
[0085] When multiple elastic elements 72 are combined with different specifications, the theoretical compression displacement of each elastic element 72 is determined according to the stiffness of each elastic element 72 and the corresponding support reaction force.
[0086] The theoretical compression displacement is used as the target compression displacement Δy of each elastic support component 7 during installation, and as the basis for the height adjustment component 8 to adjust the height of the support plate 71.
[0087] During actual installation, the actual compression displacement of the elastic element 72 detected by the displacement indicator is compared with the corresponding target compression displacement Δy, and the initial height of the corresponding support plate 71 is changed by the height adjustment component 8, so that the actual compression displacement of each elastic element 72 is gradually adjusted to the target compression displacement or its preset allowable range.
[0088] Thus, the preload of the bottom support, which was originally determined by the experience of construction workers, is transformed into a quantifiable parameter that can be calculated, tested, and accepted, enabling multiple elastic support components 7 to support the curved glass panel 100 according to the theoretical load-bearing state obtained from the design calculation.
[0089] IX. Quantitative Design of Lifting Point Hole End Distance In addition to determining the total stiffness of the bottom spring and the installation preload, the reasonable hole end distance B of the lifting point bolt hole can also be determined in reverse based on the strength check results of the lifting point hole edge area.
[0090] The minimum hole end distance that meets the strength requirements is obtained by inverse solving the strength conditions of the area around the lifting point hole, and a safety margin is set based on the minimum hole end distance.
[0091] In this embodiment, the hole end distance B can be multiplied by a safety factor of 1.2 to 1.5 based on the theoretical value obtained by inverse solution to determine the design value of the hole end distance of the actual glass hanging point hole.
[0092] Using the above method, the distance between the ends of the hanging point holes can be quantitatively determined based on the actual stress state of the curved glass panel 100 during the design phase of the hanging point location, without having to rely entirely on experience for size selection.
[0093] 10. Correspondence between calculation parameters and construction adjustments In this embodiment, the total stiffness K of the target spring 总 The target compression displacement Δy is used to determine the overall load-bearing capacity of the multiple elastic elements 72 at the bottom, and is used to determine the theoretical compression state of each elastic element 72 after installation.
[0094] Before construction, the total stiffness K of the target spring was determined through stress calculation and iterative optimization. 总 The specifications of multiple elastic elements 72 are selected according to the total stiffness of the target spring; at the same time, the target compression displacement Δy is determined according to the total stiffness of the target spring and the corresponding support reaction force.
[0095] During construction, multiple elastic support components 7 are installed in the bottom slots 6 respectively, and the initial height of each support plate 71 is adjusted by the height adjustment component 8.
[0096] After the curved glass panel 100 is seated, each elastic element 72 is compressed under the weight of the glass. The actual compression displacement of each elastic element 72 is obtained in real time through the displacement indicator.
[0097] If there is a deviation between the actual compression displacement and the target compression displacement Δy, the initial height of the support plate 71 is changed by the corresponding height adjustment component 8, thereby changing the actual compression amount of the corresponding elastic component 72, so that each support point gradually reaches the elastic support state corresponding to the design calculation.
[0098] Therefore, this embodiment establishes a correspondence between the calculated total spring stiffness and theoretical compression displacement and the actual spring compression state at the construction site, so that the design calculation results can be directly converted into on-site construction control parameters.
[0099] Using the above method, before hoisting, the bottom elastic support parameters are determined based on the specifications and stress state of the curved glass panel 100, and a reasonable load distribution is formed between the top hoisting point and the bottom elastic support through iterative calculation. During hoisting, the universal ball joint assembly 2 is used to enable the clamp assembly 3 to adaptively adjust its posture according to the local curvature of the curved glass panel 100, and the contact state and posture stability state of the clamp assembly 3 are detected by the pressure detection component and the posture detection component 41. After the preset conditions are met, the universal ball joint assembly 2 is locked. At the bottom of the glass panel, multiple independently adjustable elastic support assemblies 7 are used to elastically support the bottom edge of the glass, and the corresponding support points are adjusted according to the actual compression displacement of each elastic component 72 to make the actual support state close to the theoretical design state.
[0100] Therefore, the top clamping posture and bottom support status of the curved glass panel 100 can be adaptively adjusted simultaneously, reducing the risk of local stress concentration caused by differences in curvature of the curved glass, deviations in hoisting posture, local contact of the top clamp, and uneven bottom support, and improving the stability and safety of the curved glass panel 100 during hoisting and installation. At the same time, through the quantitative control of parameters such as the total stiffness of the target spring, the target compression displacement, the clamp posture, the contact pressure distribution, and the locking status, the reliance on manual experience in the construction process can be reduced, and traceable installation quality data can be generated.
[0101] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
