Description
Technical Field
[0001] The present application relates to the field of integrated manufacturing systems, and in particular to a modular integrated building curtain wall system and an installation method thereof. Background Art
[0002] In the field of building curtain walls, traditional construction technology has long faced the industry pain point of being difficult to balance efficiency and performance. The existing frame curtain wall system relies on on-site welding of keel structures and layer-by-layer panel installation. The complexity of the process and the construction period are growing exponentially. Statistics show that the on-site operation time of a single-layer curtain wall accounts for more than 35% of the total construction period. What is more serious is that the manual installation process leads to a high single-layer cumulative error, and the overall offset of high-rise buildings often exceeds the acceptance standard value. Although the unitized curtain wall has improved some construction efficiency through factory prefabrication, its standardized unit modules are difficult to adapt to the customization needs of curved and special-shaped buildings. The single rubber strip sealing solution used in the existing technology is prone to stress concentration under the action of temperature deformation, resulting in an excessively high leakage rate over a five-year period.
[0003] There are three core defects in the current technology: 1. The structural connection system is too rigid and lacks three-dimensional adjustability, which cannot absorb the inherent assembly cumulative errors of modular buildings; 2. The performance structural layer (waterproofing / thermal insulation / sound insulation) is constructed in layers on site, and the cross-contamination of the process leads to a high performance attenuation rate; 3. The application of BIM technology remains at the static model guidance stage, and dynamic error compensation and intelligent decision-making in the construction process have not been achieved. Especially when encountering complex curved curtain walls, the material waste rate of the existing modular solution is too high, which seriously restricts the development of green buildings.
[0004] Therefore, there is an urgent need for a modular integrated construction (MIC) curtain wall system to solve at least one of the above problems. Summary of the invention

[0042] In the field of building curtain walls, traditional construction technology has long faced the industry pain point of being difficult to balance efficiency and performance. The existing frame curtain wall system relies on on-site welding of keel structures and layer-by-layer panel installation. The complexity of the process and the construction period are growing exponentially. Statistics show that the on-site operation time of a single-layer curtain wall accounts for more than 35% of the total construction period. What is more serious is that the manual installation process leads to a high single-layer cumulative error, and the overall offset of high-rise buildings often exceeds the acceptance standard value. Although the unitized curtain wall has improved some construction efficiency through factory prefabrication, its standardized unit modules are difficult to adapt to the customization needs of curved and special-shaped buildings. The single rubber strip sealing solution used in the existing technology is prone to stress concentration under the action of temperature deformation, resulting in an excessively high leakage rate over a five-year period.
[0043] There are three core defects in the current technology: 1. The structural connection system is too rigid and lacks three-dimensional adjustability, which cannot absorb the inherent assembly cumulative errors of modular buildings; 2. The performance structural layer (waterproofing / thermal insulation / sound insulation) is constructed in layers on site, and the cross-contamination of the process leads to a high performance attenuation rate; 3. The application of BIM technology remains at the static model guidance stage, and dynamic error compensation and intelligent decision-making in the construction process have not been achieved. Especially when encountering complex curved curtain walls, the material waste rate of the existing modular solution is too high, which seriously restricts the development of green buildings.
[0044] Therefore, there is an urgent need for a modular integrated building curtain wall system to solve at least one of the above problems.
[0045] To solve the above problems, please refer to Figures 1 to 3The present application provides a modular integrated building curtain wall system, including: a MIC main structure module 10, including a building load-bearing structure and embedded connectors; a curtain wall unit module 20, including an integrated glass curtain wall unit, an aluminum curtain wall unit, a balcony railing unit and an aluminum ceiling unit at the bottom of the balcony; a modular connection structure 30, including a horizontal plug-in connection component and a vertical socket connection component, the plug-in connection component is provided with a deformation compensation gap pre-calculated according to the BIM model corresponding to the modular integrated building curtain wall system, and also includes a convex guide rail with a slope guide surface and a concave slide groove; the socket connection component is provided with a temperature deformation adaptive adjustment mechanism, the adjustment mechanism includes a memory alloy The socket structure of the casing; a BIM intelligent integrated interface (not shown in the figure, the specific installation position can be set arbitrarily according to actual needs), including a control module, which is used to obtain the real-time posture data corresponding to the curtain wall unit module through a preset laser positioning reflector; Kalman filtering is performed based on the preset parameters of the BIM model and the preset measured data of the wireless stress sensor to generate a posture correction; the MIC main structure module, the curtain wall unit module and the corresponding module installation information are generated according to the real-time posture data and the posture correction, which is used to complete the installation of the MIC main structure module, the curtain wall unit module and the modular connection structure according to the module installation information, and obtain the modular integrated building curtain wall system.
[0046] Specifically, the modular integrated building curtain wall system aims to solve the problems of low efficiency, error accumulation, performance degradation, and material waste in traditional curtain wall construction. Through modular design, intelligent integrated interface, and dynamic error compensation technology, the system achieves efficient, precise, and green curtain wall construction.
[0047] The MIC main structure module is part of the building's load-bearing structure and contains embedded connectors for quick docking with the curtain wall unit modules and modular connection structures. The position and size of the embedded connectors are precisely designed according to the BIM model to ensure compatibility with the curtain wall unit modules.
[0048] The curtain wall unit modules include glass curtain wall units, aluminum curtain wall units, balcony railing units and balcony bottom aluminum ceiling units, all of which are prefabricated in the factory. Each unit module integrates performance structural layers such as waterproofing, thermal insulation, and sound insulation, avoiding the performance degradation problem caused by on-site layered construction. The size and shape of the unit module can be customized according to the BIM model to meet the needs of curved and special-shaped buildings.
[0049] In the modular connection structure, the horizontal plug-in connection component is equipped with a deformation compensation gap, and the deformation of the module after installation is pre-calculated according to the BIM model to ensure the connection accuracy. It includes a convex guide rail with a slope guide surface and a concave slide, which facilitates the rapid positioning and installation of the module. The vertical socket connection component is equipped with a temperature deformation adaptive adjustment mechanism, and adopts a memory alloy sleeve, which can automatically adjust the connection gap when the temperature changes to avoid stress concentration and leakage problems.
[0050] The BIM intelligent integration interface includes a control module, which obtains the posture data of the curtain wall unit module in real time through the laser positioning reflector. Based on the preset parameters of the BIM model and the measured data of the wireless stress sensor, the Kalman filter algorithm is used for data fusion to generate posture corrections. Based on the real-time posture data and corrections, the module installation information is generated to guide the construction personnel to complete the precise installation.
[0051] For example, during the design phase, BIM technology can be used to build a three-dimensional model of the building curtain wall, accurately design the size and position of the MIC main structure module, curtain wall unit module and modular connection structure. In the BIM model, the deformation of the module after installation can be pre-calculated, and the deformation compensation gap and temperature deformation adaptive adjustment mechanism can be designed.
[0052] In the factory prefabrication stage, curtain wall unit modules and modular connection structures are prefabricated in the factory according to BIM model data to ensure dimensional accuracy and the integrity of the performance structure layer. Laser positioning reflectors and wireless stress sensors are pre-embedded in the curtain wall unit modules.
[0053] Install the MIC main structure module during the on-site construction phase to ensure the accurate position of the embedded connectors. Use the BIM intelligent integration interface to obtain the posture data of the curtain wall unit module in real time through the laser positioning reflector. Guide the precise installation of the curtain wall unit module based on the posture correction value generated by the BIM model and measured data. Use modular connection structures to quickly complete horizontal and vertical connections to ensure the realization of deformation compensation and temperature deformation adaptation functions. Verify the installation accuracy and performance indicators of the curtain wall system through the BIM model and wireless stress sensor data. Regularly monitor the working status of the temperature deformation adaptive adjustment mechanism to ensure the sealing performance during long-term use.
[0054] Through modular design and factory prefabrication, the on-site operation time is greatly reduced, and the construction time of a single-layer curtain wall can be shortened to less than 50% of the traditional method. Plug-in and socket-type connection components simplify the installation process and increase the construction speed. BIM intelligent integrated interface and laser positioning technology realize the precise positioning of curtain wall unit modules, and the cumulative error is controlled at the millimeter level, meeting the acceptance standards of high-rise buildings. The deformation compensation gap and temperature deformation adaptive adjustment mechanism effectively absorb the assembly error and temperature deformation, avoiding leakage and stress concentration problems. The prefabricated performance structural layer in the factory avoids cross contamination during on-site construction and ensures the long-term stability of waterproof, thermal insulation, sound insulation and other properties. The five-year leakage rate is reduced to less than 1%, which significantly improves the durability of the curtain wall system. Modular design can customize unit modules according to the BIM model to meet the needs of complex curved surfaces and special-shaped buildings, and the material waste rate is reduced to less than 5%. The concept of green building runs through the entire system design and meets the requirements of sustainable development. The dynamic application of BIM technology realizes intelligent decision-making and error compensation in the construction process, improving the construction quality and management level. Wireless stress sensors and Kalman filter algorithms provide data support for long-term monitoring and maintenance of curtain wall systems.
[0055] In summary, this modular integrated building curtain wall system effectively solves the problems of low efficiency, error accumulation, performance degradation and material waste in traditional curtain wall construction through innovative modular design, intelligent integrated interface and dynamic error compensation technology. Its high efficiency, precision and green characteristics provide a new solution for modern building curtain wall construction, with broad application prospects and significant economic and social benefits.
[0056] In some embodiments, the laser positioning reflective sheet is arranged at the four corners of the curtain wall unit module and the docking boundary of the modular connection structure, and the surface of the laser positioning reflective sheet is provided with a unique coding mark based on the coordinate system corresponding to the BIM model; the real-time posture data corresponding to the curtain wall unit module is obtained by using the preset laser positioning reflective sheet, including: performing multi-angle scanning on the laser positioning reflective sheet according to a preset laser scanner to obtain the three-dimensional coordinates and coding mark corresponding to the laser positioning reflective sheet; matching the corresponding preset coordinates in the BIM model according to the coding mark, and calculating the actual installation position, horizontal inclination angle and vertical deflection angle corresponding to the curtain wall unit module through a coordinate conversion algorithm; generating real-time posture data including three-dimensional displacement and attitude angle according to the actual installation position, horizontal inclination angle and vertical deflection angle.
[0057] The embodiment mainly relates to the setting of laser positioning reflective sheet and its application in the installation of curtain wall unit module. Through the combination of laser positioning reflective sheet and BIM model, the accurate positioning of curtain wall unit module and the acquisition of real-time posture data are realized.
[0058] The laser positioning reflective sheets are arranged at the four corners of the curtain wall unit module and the docking boundary of the modular connection structure. The surface of each laser positioning reflective sheet is provided with a unique coding mark based on the corresponding coordinate system of the BIM model, which is used for rapid identification and matching during the construction process. The laser positioning reflective sheet is scanned at multiple angles using a preset laser scanner to obtain the three-dimensional coordinates and coding mark of the reflective sheet. The scanner uses high-precision laser ranging technology to ensure the accuracy and real-time performance of the coordinate data. According to the coding mark of the laser positioning reflective sheet, the corresponding preset coordinates in the BIM model are matched. Through the coordinate conversion algorithm (such as rotation matrix and translation vector calculation), the three-dimensional coordinates obtained by scanning are converted into the actual installation position, horizontal tilt angle and vertical deflection angle. According to the actual installation position, horizontal tilt angle and vertical deflection angle, real-time posture data containing three-dimensional displacement and attitude angle are generated. The posture data is sent to the control module of the BIM intelligent integration interface through wireless transmission to guide the construction personnel to perform precise installation. The real-time posture data is compared with the preset parameters in the BIM model to calculate the installation error. The measured data of the wireless stress sensor is fused through the Kalman filter algorithm to generate the posture correction. Adjust the installation position and angle of the curtain wall unit module according to the correction amount to ensure installation accuracy. Real-time posture data and correction amount are recorded in the BIM model to form a dynamic database of the construction process. Construction personnel can view the installation progress and error in real time through mobile devices to ensure construction quality.
[0059] The embodiment realizes the accurate positioning of the curtain wall unit module and the acquisition of real-time posture data through the combination of laser positioning reflective sheet and BIM model. The multi-angle scanning and coordinate conversion algorithm of the laser positioning reflective sheet ensures the accurate calculation of the actual installation position, horizontal tilt angle and vertical deflection angle, and the cumulative error is controlled at the millimeter level. The overall offset of the high-rise building is significantly reduced, meeting the strict acceptance standards. The comparison of real-time posture data with the preset parameters of the BIM model, combined with the Kalman filter algorithm, realizes the dynamic compensation of the installation error. It effectively solves the error accumulation problem caused by manual operation in traditional construction. The unique coding identification and automatic matching function of the laser positioning reflective sheet simplifies the positioning and identification process during the construction process and shortens the installation time. The on-site operation time of a single-layer curtain wall can be reduced to less than 30% of the traditional method. The real-time posture data and construction progress are dynamically displayed through the BIM model, and the construction personnel can check the installation status and error at any time. It improves the visualization and transparency of the construction process, which is convenient for quality management and problem tracing. The application of laser positioning technology reduces the workload of manual measurement and positioning and reduces the risk of human operation errors. Especially in high-altitude operations, it significantly improves construction safety. The precise positioning and dynamic error compensation functions of the laser positioning reflector are suitable for curtain wall construction of complex curved surfaces and special-shaped buildings.
[0060] In some embodiments, the wireless stress sensor is embedded in the contact surface between the convex guide rail and the concave slide groove of the horizontal plug-in connection component, and in the contact surface between the memory alloy sleeve and the socket interface of the vertical socket connection component; the preset parameters based on the BIM model and the preset measured data of the wireless stress sensor are fused by Kalman filtering to generate a posture correction value, including: taking the preset parameters of the BIM model as the state equation and the measured data as the observation equation; establishing an adaptive filtering model according to the state equation and the observation equation; generating a process noise covariance matrix according to the deformation characteristics of the memory alloy sleeve, and dynamically adjusting the observation noise weight corresponding to the covariance matrix according to the sampling frequency of the wireless stress sensor; iteratively calculating the posture correction value under the minimum variance according to the adaptive filtering model and the covariance matrix; the posture correction value includes a horizontal plug-in gap compensation value, a vertical socket angle compensation value and a preload threshold between modules.
[0061] The embodiments mainly involve the embedding of wireless stress sensors and their application in dynamic error compensation. By embedding wireless stress sensors into the contact surface of modular connection structures and combining BIM models and Kalman filter algorithms, stress monitoring and posture correction during the installation of curtain wall unit modules are achieved. Wireless stress sensors are embedded in the contact surface between the convex guide rail and the concave slide groove of the horizontal plug-in connection component to monitor the contact stress during the plug-in process. Wireless stress sensors are embedded in the contact surface between the memory alloy sleeve and the socket interface of the vertical socket connection component to monitor the contact stress and temperature deformation during the socket process.
[0062] The preset parameters of the BIM model are used as the state equation, including the design size, material properties and installation position of the modular connection structure. The measured data of the wireless stress sensor is used as the observation equation, including contact stress, temperature deformation and preload between modules.
[0063] An adaptive filtering model is established based on the state equation and observation equation to describe the dynamic error during the installation of curtain wall unit modules. The model takes into account the deformation characteristics of the memory alloy sleeve and the sampling frequency of the wireless stress sensor to ensure the accuracy and real-time performance of the filtering process.
[0064] The process noise covariance matrix is generated according to the deformation characteristics of the memory alloy sleeve to describe the influence of temperature deformation on the installation error. The observation noise weight is dynamically adjusted according to the sampling frequency of the wireless stress sensor to ensure the matching of the filtering result with the actual data.
[0065] According to the adaptive filtering model and covariance matrix, the Kalman filter algorithm is used to iteratively calculate the pose correction under the minimum variance. The pose correction includes: Horizontal plug-in gap compensation value: used to adjust the installation gap of the horizontal plug-in connection component to ensure the plug-in accuracy. Vertical socket angle compensation value: used to adjust the installation angle of the vertical socket connection component to ensure the socket accuracy. Inter-module preload threshold: used to control the preload of the modular connection structure to avoid stress concentration and material fatigue.
[0066] According to the posture correction, the BIM intelligent integration interface guides construction workers to adjust the installation position and angle of the curtain wall unit module. Real-time monitoring of the contact stress and temperature deformation of the modular connection structure ensures the stability and safety of the installation process.

[0124] Please refer to Figure 4 An embodiment of the present application provides an installation method of a modular integrated building curtain wall system. The execution device of the method is a control module of the modular integrated building curtain wall system provided in any embodiment of the present application.
[0125] The provided method includes steps S101 to S104, wherein the control module may be a handheld terminal, a notebook computer, a wearable device or a robot, etc. The method is used to implement steps S101 to S104 and their corresponding embodiments.
[0126] Step S101. Acquire the real-time position data corresponding to the curtain wall unit module through the preset laser positioning reflector.
[0127] Specifically, laser positioning reflectors are installed at key locations (such as the four corners and the center point) of the curtain wall unit module to reflect laser signals. The arrangement of the reflectors meets the preset posture requirements of the BIM model to ensure the comprehensiveness and accuracy of data collection. A high-precision laser scanner is used to emit a laser beam, which is irradiated onto the reflector to obtain the reflected signal. The spatial coordinates and posture data (including position and angle) of the reflector are calculated through the built-in algorithm of the laser scanner. The raw data collected by the laser scanner is converted into real-time posture data of the curtain wall unit module, including: Position data includes the three-dimensional coordinates (X, Y, Z) of the center point of the module. Angle data includes the pitch angle (Pitch), yaw angle (Yaw) and roll angle (Roll) of the module.
[0128] Step S102: Perform Kalman filtering fusion based on the preset parameters of the BIM model and the preset measured data of the wireless stress sensor to generate a posture correction value.
[0129] Specifically, the preset posture parameters of the curtain wall unit module, including theoretical position, angle and stress distribution, are stored in the BIM model. The preset parameters serve as the "prediction value" of the Kalman filter. Wireless stress sensors are installed at the connection nodes of the curtain wall unit module to measure the axial stress and shear stress in real time. The measured data serves as the "observation value" of the Kalman filter. The Kalman filter algorithm fuses the preset parameters of the BIM model with the measured data of the wireless stress sensor to generate the optimal posture correction. Through Kalman filtering, the preset parameters of the BIM model are fused with the measured data, which improves the accuracy of the posture correction.
[0130] Step S103: Generate the MIC main structure module, curtain wall unit module and corresponding module installation information according to the real-time posture data and posture correction amount.
[0131] Specifically, the real-time posture data obtained in step S101 is integrated with the posture correction amount generated in step S102 to generate corrected posture data. The corrected posture data includes the actual position and angle of the module. Based on the corrected posture data, the installation information of the MIC main structure module, curtain wall unit module and modular connection structure is generated, including: Lifting path: the lifting trajectory and adjustment amount of the module. Preload force parameter: the preload force application gradient of the connection node. Processing size adjustment amount: the adjustment amount of the module processing size. The corrected posture data and installation information are updated to the BIM model to ensure that the model is consistent with the actual construction status.
[0132] Step S104: Complete the installation of the MIC main structure module, the curtain wall unit module and the modular connection structure according to the module installation information to obtain the modular integrated building curtain wall system.
[0133] Specifically, according to the installation information generated in step S103, the installation of the MIC main structure module, the curtain wall unit module and the modular connection structure is completed in sequence. During the installation process, the posture data and stress distribution are monitored in real time to ensure the installation accuracy and safety. After the installation is completed, the system is comprehensively inspected by laser scanners and wireless stress sensors to verify the installation quality. The inspection data is compared with the BIM model to ensure that the system meets the design requirements. The key data (such as posture data and stress data) in the installation process are recorded in the BIM model to form a construction process database. Based on data analysis, the subsequent construction process is optimized. The system installation quality is ensured through accurate installation information and real-time monitoring.
