Description

Technical Field

[0001] The invention relates to the technical field of curtain wall window structure installation, and in particular to a rapid assembly method of a modular curtain wall window structure. Background Art

[0002] In the construction industry, curtain wall systems are an important part of modern building design. They not only ensure the appearance and functionality of buildings, but also play a key role in the energy efficiency and environmental adaptability of buildings. Curtain wall windows, as part of the curtain wall system, are usually realized through prefabricated modular components that are assembled on the construction site. Current technology mainly relies on traditional construction drawings and manual measurements to guide the installation of curtain wall windows, which involves a lot of manual operations and on-site adjustments.

[0003] However, curtain wall window installation that relies on traditional methods has multiple problems. First, manual measurement and on-site adjustment are not only time-consuming, but may also lead to installation errors, affecting the quality and performance of the entire curtain wall system. Second, this method requires high skills from workers, is not conducive to the rapid training of new workers, and also increases the complexity of construction and potential safety risks. In addition, traditional methods have difficulty in dealing with complex or non-standardized building designs, which limits the flexibility and innovation of the design.

[0004] Therefore, it is very necessary to develop a new rapid assembly method for modular curtain wall window structures. Summary of the invention

[0068] Consider possible future building extensions or renovations in the design of the opening pattern to ensure long-term suitability.

[0069] The beneficial effects of the technical solution provided by this application include:

[0070] (1) By using Building Information Modeling (BIM) technology, the present invention is able to plan the installation of curtain wall windows in detail during the design phase of the building. This not only ensures installation accuracy, but also improves the consistency of the entire curtain wall system with the building structure. The integration of detailed three-dimensional geometric information, physical properties and functional properties of the BIM model provides precise guidance for construction, thereby reducing the need for on-site adjustments and potential errors. (2) By pre-dividing the installation area in the BIM model and determining the specific specifications of the window frame unit, the construction team can carry out on-site operations more quickly. In addition, the optimization steps in the simulated assembly process allow possible installation problems to be solved in advance, reducing the time to solve problems on site, thereby speeding up the entire installation process. (3) The optimized pre-assembly process reduces the possibility of material waste and duplication of work. Through accurate models and pre-calculated installation instructions, materials and human resources can be used more efficiently, further reducing the total cost of the project. (4) By simulating the assembly process in the BIM model and optimizing the position of the window frame unit, the present invention is able to ensure that each component is installed in the optimal position. This not only improves the stability of the structure, but also enhances the building's resistance to external environmental factors (such as wind pressure and earthquakes). BRIEF DESCRIPTION OF THE DRAWINGS

[0071] Figure 1 This is a flow chart of a modular curtain wall window structure rapid assembly method provided in the first embodiment of the present application. DETAILED DESCRIPTION

[0072] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0073] The first embodiment of the present application provides a method for rapid assembly of a modular curtain wall window structure. Figure 1 , which is a schematic diagram of the first embodiment of the present application. Figure 1 A first embodiment of the present application provides a method for rapid assembly of a modular curtain wall window structure, which is described in detail.

[0074] Step S101: Create a BIM model of a building, wherein the BIM model includes three-dimensional geometric information, physical property information, and functional property information of the building.

[0075] In step S101, the detailed process involves creating a building information model (BIM) of a building, which not only stores the three-dimensional geometric information of the building, but also integrates the physical attribute information and functional attribute information. This step is the basis for achieving efficient and accurate modular curtain wall window structure installation.

[0076] First, accurate 3D geometric data of the building needs to be collected and input. This includes the building's external outline as well as the internal structural layout, such as the location and size of floors, walls, windows, doors and other structural elements. This data is usually obtained through on-site measurements or converted from original digital drawings during the architectural design phase.

[0077] Next, the physical property information needs to include the type, quality, thermal performance, acoustic performance, etc. of the material, which is crucial for evaluating the environmental adaptability and durability of the building. For example, the material of the wall and window frames may directly affect the thermal insulation and energy efficiency of the building.

[0078] In addition, the input of functional attribute information involves the use of the building, such as office, residential or commercial, which determines the requirements for its internal environmental quality, such as optimization of natural light, ventilation and pedestrian flow. This part of information helps the design team decide how to layout curtain wall windows to maximize their functional benefits, such as lighting and visual comfort.

[0079] The process of creating a BIM model requires the use of professional BIM software, such as Autodesk Revit. These software are able to support highly detailed data input and allow users to view and modify the model through a visual interface. During the model creation process, any conflicts or problems that may arise in the design can be detected in real time and adjustments can be made accordingly. For example, if it is detected that the predetermined position of a curtain wall window conflicts with the main structural beam, technicians can immediately adjust the window position or size to avoid this conflict.

[0080] Furthermore, creating a BIM model of a building includes:

[0081] When creating a BIM model, consider the climate data and geographic location information of the building’s location;

[0082] Include the building’s seismic design parameters and energy rating in the BIM model;

[0083] Interfacing the BIM model with local building codes and safety standards ensures that the model meets all relevant legal and technical requirements.

[0084] First, technicians need to collect and analyze climate data and geographic location information for the building's location. This includes but is not limited to the region's temperature range, precipitation, wind speed, and unique climatic conditions (such as fog, dust, high humidity, etc.). In addition, the analysis of the geographic location should also take into account the frequency of seismic activity, the impact of terrain, and the relative location to major cities or industrial areas. This information is crucial for predicting the environmental challenges that the building may encounter in actual use, so it must be recorded and analyzed in detail in the BIM model.

[0085] Next, the building's seismic design parameters and energy efficiency rating are entered into the BIM model. Seismic design parameters are based on earthquake risk assessment and include seismic performance standards for building structures, such as the layout of shear walls, the connection strength of floor slabs, and the distribution of building mass. Energy efficiency ratings involve factors such as the building's insulation performance, the heat transfer coefficient of windows, and the materials and technologies used. These data are essential for creating a building model that is both safe and energy-efficient.

[0086] Finally, the created BIM model is connected with local building codes and safety standards. This step requires technicians to be familiar with local building codes, safety standards, and any special building regulations. Technicians will use professional software such as the specification checking tool in Autodesk Revit to ensure that every design element in the model meets or exceeds the requirements of these standards. This includes not only structural safety checks, but also compliance assessments in many aspects such as fire protection, waterproofing, and environmental protection.

[0087] Through these steps, a comprehensive BIM model that meets local environmental and regulatory requirements can be created, which provides a solid foundation and guarantee for the rapid assembly of the subsequent modular curtain wall window structure. Such a model can greatly improve the execution efficiency and safety of the construction project and ensure that the building exhibits excellent environmental adaptability and long-term durability during its life cycle.

[0088] Step S102: dividing the area where the curtain wall window structure is to be installed in the BIM model, and determining the type, quantity and size of the modular window frame units according to the shape and size of the area.

[0089] In step S102, it is described in detail how to determine the specific area where the curtain wall window structure is installed in the previously created building information model (BIM), and accurately set the type, quantity and size of the modular window frame units according to the specific shape and size of the area. This step is the key link to ensure that the curtain wall window is perfectly integrated with the architectural design and function.

[0090] First, technicians need to analyze and select the installation location of the curtain wall windows in detail in the BIM model. This usually involves a visual review of the building's facade and consideration of the internal functional areas to ensure that the selected area meets both the aesthetic requirements of the building and meets functional needs such as light entry, sight lines, and other needs. In addition, the structural support capacity of the selected area needs to be evaluated to determine whether it can carry the predetermined curtain wall window structure.

[0091] Next, the type of modular window frame unit is determined based on the shape and size of the defined installation area. The selection of modular window frames is based on the material (such as aluminum, steel or glass), the design of the window frame (such as double-glazed windows or single-glazed windows), and the necessary functional configuration (such as opening method, security features, etc.). Each type of window frame has specific physical and functional properties that must be matched to the overall requirements of the building.

[0092] Then, based on the selected window frame type, the number and size of the required window frames are determined. The number is calculated based on the area to be covered and the standard size of the window frame units to achieve the best coverage in terms of economy and aesthetics. The size of the window frame is precisely measured and calculated according to the specific dimensions of the area to ensure that each window frame unit can be accurately adapted to its installation position, ensuring the accuracy of the installation and the sealing of the building.

[0093] This step can be implemented through the tools and functions in BIM software, which supports selection and adjustment through an intuitive interface, while providing real-time feedback and automatic calculation functions to ensure the correctness and rationality of all parameters. In addition, BIM software can simulate the potential impact of different choices on the overall performance of the building (such as energy efficiency, safety and comfort), thereby supporting a more scientific and comprehensive decision-making process.

[0094] Through precise area division and determination of window frame units, step S102 lays a solid foundation for subsequent manufacturing and installation work, ensures the overall quality and performance of the curtain wall window structure, and also provides a clear and specific execution guide for the construction team.

[0095] Furthermore, dividing the area where the curtain wall window structure is to be installed in the BIM model includes:

[0096] Analyze sunlight and wind pressure data for the intended installation area to determine the optimal layout of window frame units;

[0097] Adjust the distribution of window frame units according to the building's usage function and internal space layout;

[0098] Conduct a sustainability assessment of the type, quantity and size of window frame units, including the environmental impact and recyclability of the materials.

[0099] First, analyzing the sunlight and wind pressure data for the intended installation area is a critical first step. This analysis involves collecting historical meteorological data for a specific location, such as the number of hours of direct sunlight, seasonal changes, and the direction and strength of wind. This data can be obtained through public resources from the meteorological department or specific weather service companies. Technicians need to use this information to evaluate the sunlight conditions and wind pressure effects on various parts of the building during different time periods to determine the optimal layout of window frame units on the building. For example, window frames facing the direction with the most sunlight may require enhanced insulation, while window frames facing strong wind areas require special structural strength to resist wind pressure.

[0100] Next, the distribution of window frame units is adjusted according to the building's functional use and internal space layout. This step requires a deep understanding of the functional areas of the building. For example, if the building is an office, the natural light requirements and view requirements of the office area need to be considered; if it is a residence, more consideration may be needed for privacy and noise control. Based on these functional requirements, technicians will use BIM software to adjust the position and size of window frame units in the model to ensure that the lighting and ventilation of each space are optimal.

[0101] Finally, a sustainability assessment of the window frame unit is conducted, which involves an analysis of the environmental impact and recycling capacity of the window frame materials. This assessment includes examining the energy consumption and emissions during the production of the selected materials, the energy efficiency during use, and the recycling capacity after the life cycle ends. This requires technicians to select materials that meet green building standards, such as recyclable metals or wood with environmental certifications. In addition, the window frame design should facilitate future maintenance and replacement to extend service life and reduce waste.

[0102] Through these detailed steps, it is ensured that the design of the curtain wall window structure not only meets the actual use needs, but also meets the requirements of environmental sustainability.

[0103] Step S103: Generate corresponding window frame unit models in the BIM model according to the determined types, quantities and sizes of modular window frame units, wherein each window frame unit model includes a frame and window sashes embedded in the frame, and a connecting structure arranged on the frame.

[0104] In step S103, a process is provided for generating corresponding window frame unit models according to the type, quantity and size of the modular window frame units previously determined in the BIM model. This step involves the specific design of each window frame unit, including the comprehensive modeling of the frame, sash and connection structure, ensuring that it can accurately adapt to the design intent and functional requirements.

[0105] First, a detailed model of each window frame unit must be created using the modeling tools in the BIM software. This involves accurately drawing or importing the frame structure of the window frame, which is usually made of metal or other structurally strong materials with the necessary size and shape to support the sash and connecting structure.

[0106] Next, the corresponding window sashes are embedded in each frame. The design of the window sashes needs to take into account functional requirements such as light transmission, thermal insulation, wind protection and safety features. Window sashes are usually made of glass or other transparent materials and may include double or triple glazing to enhance their insulating properties. At this stage, every detail of the window sash, such as the frame, opening mechanism (such as sliding, casement or tilting), and sealing strips, needs to be accurately represented in the model.

[0107] In addition, the connection structures must be integrated into the model. These structures are key components for installing the window frame unit into the building wall, including but not limited to anchors, bolts, and joints. The connection structure must be designed to ensure that the window frame unit can be firmly fixed to the wall opening and can withstand the influence of the external environment (such as wind pressure and temperature changes).

[0108] In the process of creating the window frame unit model in the BIM model, it is necessary to continuously verify and adjust to ensure the compatibility between the components and the integrity of the overall structure. After the model of each window frame unit is created, it will be marked and recorded in the BIM database for query and reference in the subsequent simulation and installation process.

[0109] This step ensures that each modular window frame unit meets the design and functional standards, while ensuring efficiency and accuracy in the actual assembly process. The completion of this stage provides the necessary basic data and detailed support for the assembly of the entire curtain wall window structure, and is a key link in the subsequent construction preparation.

[0110] Furthermore, generating a corresponding window frame unit model in the BIM model according to the determined type, quantity and size of the modular window frame unit includes:

[0111] Virtual stress testing was performed on each window frame unit model to assess its structural integrity and long-term durability.

[0112] First, it is necessary to ensure that each window frame unit model in the BIM model has been accurately generated according to the guidance of step S103, including the frame, sash and connection structure of the window frame. Once these models are correctly set in the BIM, the next task is to perform virtual stress testing on each model.

[0113] The process of conducting virtual stress testing usually involves the use of professional engineering simulation software such as ANSYS or Autodesk Simulation. These software can simulate various physical forces acting on the window frame unit in a virtual environment, such as gravity, wind pressure, earthquake force, etc. The technician will set the corresponding test parameters according to the specific installation location and expected use environment of the window frame unit. For example, if the window frame is located in a high wind pressure area, it will be subjected to a specific wind pressure loading test; if the building is located in an earthquake-prone area, an earthquake force simulation will be performed.

[0114] After setting the appropriate test parameters, the technician will start the simulation and the software will calculate the stress distribution and deformation of the window frame unit under various loading conditions. This data will be analyzed in detail to assess whether there are any weaknesses that may cause structural failure. Special attention will be paid to those areas of stress concentration or excessive deformation, which are often potential structural problems.

[0115] If the test results show that some parts of the window frame unit model do not meet the structural safety requirements, technicians will make design adjustments based on this feedback. This may include strengthening the structural frame of the window frame, replacing it with a stronger material, or adjusting the design of the connecting structure to improve its load-bearing capacity and resilience.

[0116] Once these adjustments are made, virtual stress testing is performed again to ensure that all modifications effectively address the issues previously identified and to ultimately confirm that each window frame unit model meets the required safety and durability standards. This approach not only prevents potential structural problems before actual manufacturing and installation, but also significantly improves the safety and reliability of construction projects.

[0117] Through these detailed virtual stress tests, the risk of problems occurring during actual construction can be greatly reduced, ensuring that the window frame unit maintains high performance throughout its expected life cycle.

[0118] Step S104: performing opening processing on the area where the curtain wall window structure is to be installed in the BIM model, generating a wall opening model matching the size of the modular window frame unit, and adding a fixing model matching the connection structure at the corresponding position of the wall opening model.

[0119] In step S104, it is explained in detail how to process the opening in the already created and prepared building information model (BIM), and how to accurately generate a wall opening model that matches the modular window frame unit size. In addition, this step also covers the process of adding a fixing model that matches the window frame connection structure in the corresponding wall opening model.

[0120] First, the technician needs to determine the specific opening position of the wall in the divided area in the BIM model. This usually involves a detailed analysis of the wall structure to ensure that the opening will not affect the structural safety of the building. Using professional architectural design software, such as Revit, the position and size of each opening can be accurately marked in the BIM model. These marks must strictly correspond to the size of the modular window frame unit determined in step S102.

[0121] Next, the openings are processed. This involves calculating the specific size and shape of the openings to ensure they fit perfectly into the designed window frame units. In the software, technicians will use cutting tools to accurately cut the wall according to the predetermined marks to form the openings. This process needs to take into account factors such as the building's insulation, waterproofing and structural load-bearing capacity to ensure that the wall at the opening can cooperate with the newly installed window frame to maintain its original function and safety performance.

[0122] In addition, adding the fixing model is an important part of this step. Fixings, such as anchor bolts, steel bars or joint metal plates, are key elements that connect the window frame to the building structure. In the BIM model, technicians need to design the location and installation method of the fixings in detail according to the connection structure of the window frame unit. These fixing models will be directly integrated into the wall opening model so that during the actual installation process, the lifting equipment can accurately position and fix the window frame unit in the predetermined position.

[0123] By executing these steps, technicians can ensure that each window frame unit not only accurately matches the opening of the building, but also that its fixing structure can be reliably installed and fixed to the building. The entire process needs to be completed in BIM software, and it is necessary to ensure the accuracy and update of all data so that subsequent steps can be seamlessly connected, thereby effectively improving the efficiency and safety of the entire installation process. This step is a key link in realizing the rapid assembly method of modular curtain wall windows, ensuring the smooth progress of the assembly work.

[0124] Furthermore, the area where the curtain wall window structure is to be installed is opened in the BIM model to generate a wall opening model matching the size of the modular window frame unit, including:

[0125] Implement enhanced virtual verification in wall opening models to ensure accurate opening location and safety margins;

[0126] Consider possible future building extensions or renovations in the design of the opening pattern to ensure long-term suitability.

[0127] First, the technician needs to locate and mark the specific areas where the curtain wall windows will be installed in the BIM. These areas are selected based on the comprehensive analysis of the building's purpose, internal layout, and environmental factors in step S102. Once these areas are determined, the technician will begin to design the wall opening model in detail.

[0128] The next critical step is to implement enhanced virtual verification. This process involves using advanced simulation tools to conduct a series of virtual tests on the planned wall opening locations in the BIM software. These tests simulate the impact of the opening on the structural integrity of the building and verify whether the size and location of the opening will affect the structural safety of the building. For example, through stress analysis and load testing, it is ensured that the opening will not be located in a load-bearing wall or affect the basic structural integrity of the building. In addition, it is ensured that all designed opening boundaries remain within safety standards and avoid adverse effects on other functional areas of the building.

[0129] After the necessary virtual verification has been carried out and all safety and accuracy standards have been met, the technicians will further optimize the opening model. This includes considering the possible future expansion or renovation needs of the building. For example, when designing the opening, additional space will be left blank or modular interfaces will be installed, so that if the window frame needs to be replaced or the opening size needs to be adjusted in the future, it can be done easily without large-scale structural changes. This forward-looking design thinking is to ensure the long-term suitability and flexibility of the building to adapt to possible changes in space requirements or technological updates in the future.

[0130] This approach not only improves the efficiency of building project execution, but also enhances the sustainability and adaptability of buildings, ensuring that every step from design to implementation meets the highest safety and quality standards.

[0131] Step S105: Based on the generated window frame unit model and the generated wall opening model, simulating the assembly process of the curtain wall window structure in the BIM model; optimizing the installation position and sequence of the window frame unit model in the simulated assembly process; and generating corresponding installation instructions according to the optimized installation position and sequence.

[0132] In step S105, it is explained how to simulate the assembly process of the curtain wall window structure in the building information model (BIM), optimize the installation position and sequence of the window frame unit model, and finally generate the installation instructions. This step is crucial because it is directly related to the accuracy and efficiency of the curtain wall window structure assembly.

[0133] First, the window frame unit model generated in step S103 is integrated with the wall opening model created in step S104 using the advanced simulation function of the BIM software. This integration process involves accurately placing the window frame units at their corresponding opening positions in the BIM environment, ensuring that the frame and connection structure of each window frame unit are perfectly aligned with the fixings of the wall opening.

[0134] Next, the assembly simulation is performed. In this process, BIM software is used to dynamically simulate the movement path of the window frame unit from the initial position to the final installation position. During this process, the software automatically detects and prompts any possible collision or alignment issues, so that the position or installation sequence of the window frame unit can be adjusted in real time to avoid these problems. The simulation process also takes into account the physical limitations that may be encountered in actual construction, such as the feasibility of the lifting path and the access space for installation tools.

[0135] After completing the simulation, the software automatically generates detailed installation instructions based on the installation position and sequence of the optimized window frame unit model. These instructions include the precise location and installation sequence of each window frame unit, the required fixings and connection details, and any special handling instructions. The installation instructions will be recorded in detail and can be exported to a format that can be used by the construction team, such as PDF, or directly integrated into mobile devices used on the construction site.

[0136] The generated installation instructions not only guide the lifting equipment operators to correctly lift the window frame units to the specified location, but also help the on-site staff to accurately perform each step of the installation process, ensuring that each window frame unit can be accurately installed according to the design intent, thereby ensuring the quality and performance of the entire curtain wall system.

[0137] Through the rigorous implementation of this step, the uncertainty and potential errors in the on-site installation process can be greatly reduced, and the overall efficiency and quality of curtain wall window structure assembly can be improved. This step ensures that every link from design to implementation is precisely matched and meets design specifications and building safety standards.

[0138] Furthermore, the optimizing the installation position and sequence of the window frame unit model during the simulated assembly process includes:

[0139] In the simulated assembly process, the priority P of each window frame unit is calculated according to the following formula 1: i :

[0140]

[0141] Among them, w ik is the weight of the kth attribute of the i-th window frame unit; v ik is the actual value of the kth attribute of the i-th window frame unit; c ijis the compatibility coefficient between the i-th window frame unit and the j-th window frame unit; is the average compatibility coefficient of all window frame units with the jth window frame unit; n is the total number of attributes of the window frame unit; m is the total number of window frame units;

[0142] Among them, the compatibility coefficient c ij Calculate according to the following formula 2:

[0143]

[0144] Among them, a ij is the score of material compatibility between the i-th window frame unit and the j-th window frame unit; b ij The score of the design style compatibility between the i-th window frame unit and the j-th window frame unit; h i and h j are the installation heights of the i-th window frame unit and the j-th window frame unit respectively; k and p are adjustment coefficients;

[0145] Average compatibility coefficient Calculate according to the following formula 3:

[0146]

[0147] Where m is the total number of window frame units;

[0148] According to the calculated priority P i , determine the installation order of each window frame unit; and use the simulated annealing algorithm to optimize the installation position of the window frame unit to reduce the structural stress and potential safety risks caused by improper installation order and position.

[0149] Formula 1 is defined as:

[0150]

[0151] Here, P i Indicates the priority of the i-th window frame unit. The higher the priority, the earlier it is installed. The calculation method is as follows:

[0152] w ik is the weight of the kth attribute of the i-th window frame unit. This weight defines the relative importance of each attribute in the overall performance evaluation of the window frame unit. The weight is usually determined based on design specifications or empirical data.

[0153] v ik is the actual value of the kth attribute of the i-th window frame unit. These values ​​are derived from the specific design parameters of the window frame unit, such as size, material type or other technical specifications.

[0154] c ijis the compatibility coefficient between the i-th window frame unit and the j-th window frame unit. The compatibility coefficient reflects the coordination of the two window frame units in installation and performance.

[0155] is the average compatibility coefficient of all window frame units with the jth window frame unit. The average is calculated by calculating all the individual compatibility coefficients c ij Averaging yields , as defined in Equation 3.

[0156] n is the total number of attributes of the window frame unit, and m is the total number of window frame units.

[0157] Formula 2 is defined as:

[0158]

[0159] Here, c ij It represents the compatibility coefficient between the i-th window frame unit and the j-th window frame unit, and is calculated as follows:

[0160] a ij and b ij are the scores of the i-th and j-th window frame units in terms of material compatibility and design style compatibility, respectively. These scores are derived based on predetermined standards or test results.

[0161] h i and h j is the installation height of the i-th and j-th window frame units, which affects the complexity and visual effect of the window frame unit installation.

[0162] k and p are adjustment coefficients used to adjust the sensitivity and height correlation effects of the compatibility score, which can be obtained based on experimental data.

[0163] Formula 3 is defined as:

[0164]

[0165] here, is the average compatibility coefficient of all window frame units with the jth window frame unit, which is calculated by averaging the compatibility coefficients of all window frame units.

[0166] Through these detailed formulas and parameter explanations, the process of optimizing the installation position and sequence of window frame unit models in the BIM model can be understood and implemented. In addition, this calculation method helps ensure that the installation of each window frame unit can minimize structural stress and potential safety risks, thereby improving the performance and safety of the entire curtain wall system.

[0167] Furthermore, the material compatibility score a between the i-th window frame unit and the j-th window frame unit is ijCalculate according to the following formula 4:

[0168]

[0169] Among them, k(M i ,M j ) is an interaction coefficient based on two materials, which reflects the material M of the i-th window frame unit. i and the material M of the jth window frame unit j the extent of possible chemical and physical reactions upon contact; and are the material attribute scores of the i-th window frame unit and the j-th window frame unit, and the material attribute score of the window frame unit P M Calculate according to the following formula 5:

[0170] P M =ω1·D M +ω2·T M +ω3·C M (5)

[0171] Among them, D M Indicates the durability rating of the material of the window frame unit; T M Indicates the thermal expansion coefficient score of the material; C M Indicates the corrosion resistance score of the material; ω1, ω2, ω3 are weight factors.

[0172] First, the material compatibility score a ij is calculated by formula 4, which takes into account the interaction coefficient κ (M i ,M j ) and the material property scores of the two window frame elements and The interaction coefficient k(M i ,M j ) is a specially designed parameter to quantify the extent of chemical and physical reactions that two materials may experience when in contact. This assessment is very important because reactions between different materials may affect the performance and durability of the window frame unit. For example, certain metals may accelerate the corrosion process due to electrochemical reactions when in contact.

[0173] Next, the material property score P M It is calculated by formula 5, which involves the scoring of several key attributes, each of which has its corresponding weight factor. Specifically:

[0174] D MIndicates the durability rating of a material, which reflects the material's ability to withstand environmental and mechanical loads. Durability is a key factor in window frame material selection, directly affecting the window frame's service life and maintenance frequency.

[0175] T M The coefficient of thermal expansion score is a material's ability to maintain volume and shape stability under temperature changes. Considering the coefficient of thermal expansion is particularly important when designing window frames, as different thermal expansion characteristics can cause structural stress and deformation.

[0176] C M Indicates the corrosion resistance rating of the material, which is essential to improve the durability of window frames in various environmental conditions, especially in chemical corrosion or salt spray environments.

[0177] ω1, ω2, ω3 are weighting factors for these properties, which are adjusted according to the relative importance of the material properties in the overall window frame performance.

[0178] In this way, the material compatibility between the two window frame units can be systematically evaluated and optimized to ensure that they can show the best performance and longest durability during actual installation and use. Such detailed calculations not only help optimize the design, but also help prevent possible problems in the future, thereby improving the reliability and safety of the entire curtain wall system.

[0179] Furthermore, the score b of the design style compatibility between the i-th window frame unit and the j-th window frame unit is ij Calculated according to the following formula 6:

[0180]

[0181] Among them, s i and j Represents the design style scores of the i-th and j-th window frame units, ranging from 0 to 100; r ij is a correction factor calculated based on the visual and aesthetic compatibility of two window frame units, taking into account the similarity of color, texture and shape.

[0182] First, each window frame unit is assigned a design style score s i and j , these scores range from 0 to 100. This score is a quantitative assessment based on the design features of the window frame unit such as simplicity of lines, complexity of patterns, and overall sense of style. For example, a window frame with a modern minimalist design may receive a high score, while a window frame with complex decoration or traditional style may score on a different scoring scale. This scoring method allows for quantification of the design style of each window frame unit, providing a basis for subsequent compatibility evaluation.

[0183] Next, the difference in design style between the two window frame units is calculated. This is done by calculating the absolute difference in the design style scores of the two window frame units |s i -s j |, the smaller the difference, the closer the two are in design style. Then, this difference is subtracted from 100 and divided by 100 to get a proportional value between 0 and 1, reflecting the consistency of the design style of the two window frame units.

[0184] In addition, the correction factor r is introduced ij , which is a coefficient calculated based on the similarity of the color, texture, and shape of the two window frame units. This coefficient is adjusted according to how well the window frame units are visually compatible. For example, if the two window frame units are a close match in color and texture, then r ij This coefficient further refines the initial compatibility assessment based on the difference in style scores, ensuring that the scores reflect not only the numerical similarity of the design styles, but also the actual harmony in terms of visual and aesthetics.

[0185] Finally, the design style compatibility score is b ij It is obtained by multiplying the design style consistency ratio by the correction factor. This calculation provides a quantitative indicator to evaluate the degree of visual coordination between two window frame units, helping designers and installation teams ensure the overall aesthetic consistency and appeal of the entire curtain wall system.

[0186] This method can systematically evaluate and optimize the design style compatibility between window frame units, ensuring the best visual effect and design consistency during actual installation and use. This not only helps to improve the overall aesthetics of the building, but also increases the market appeal and value of the curtain wall.

[0187] Furthermore, the use of a simulated annealing algorithm to optimize the installation position of the window frame unit to reduce structural stress and potential safety risks caused by improper installation sequence and position includes:

[0188] Step a: Initialize the parameters of the simulated annealing algorithm, including the initial temperature T0, the cooling rate α, and the stop temperature T min ;

[0189] Step b: setting the initial solution to a random or experience-based window frame unit installation position;

[0190] Step c: At the current temperature, repeat the following steps c1-c4 until equilibrium is reached:

[0191] Step c1: randomly select a window frame unit and try to change the position of the window frame unit;

[0192] Step c2: Calculate the system energy E(s) using the following formula 7, where s represents the state of the window frame unit:

[0193]

[0194] Where dist(i,j) represents the distance between window frame units i and j;

[0195] Step c3: Calculate the energy difference ΔE=E(s new )-E(s old ), where s new Indicates the new state after changing the position of the window frame unit; s old Indicates the old state before changing the position of the window frame unit;

[0196] Step c4: If ΔE<0, accept the new state s new as the current solution; otherwise, with probability p = e -ΔE / T1 Accept the new state, where T1 is the current temperature;

[0197] Step d: According to the following formula 8, the system temperature T after cooling is obtained:

[0198] T=α×T1 (8)

[0199] Step e: If the system temperature T after cooling is not lower than T min , then return to step c to continue iteration; otherwise, the final position of the window frame unit is determined as the optimized solution.

[0200] First, the initialization of the simulated annealing algorithm is a key starting step. The initial parameters of the algorithm include the initial temperature T0, which is the temperature at which the algorithm starts. High temperature allows more possible solutions to be explored in the early stages of optimization; the cooling rate α, which is a factor that determines the speed at which the temperature drops, affecting the algorithm's search depth and speed; and the stop temperature T min , which is the minimum temperature before the algorithm stops, ensuring that the algorithm does not stop too early and miss a better solution.

[0201] Next, the initial solution is set according to the installation position of the window frame unit. This initial solution can be randomly generated or set based on past experience or simple heuristic rules. The purpose is to provide a starting point so that the algorithm can start exploring possible better solutions.

[0202] During the algorithm operation, repeated iterative optimization is performed. These steps include:

[0203] 1. Randomly select a window frame unit model and try to change its position. This step is to generate new possible solutions.

[0204] 2. Calculate the energy of the system using Equation 7:

[0205]

[0206] Where E(s) represents the energy of the system, c ij is the compatibility coefficient between window frame units, and dist(i,j) is the distance between window frame units i and j. This calculation helps evaluate the efficiency and effectiveness of the current window frame unit layout.

[0207] 3. Calculate the energy change ΔE=E(s new )-E(s old ),

[0208] where s new is the new state after the attempted change, s old is the original state. The energy difference ΔE determines whether the new state is accepted. If ΔE<0, the new state brings lower energy and should be accepted; if ΔE≥0, the acceptance probability of the new state is p=e -ΔE / T1 , where T1 is the current temperature. This reflects the characteristic of the simulated annealing algorithm of "accepting poor solutions" to avoid falling into the local optimal solution.

[0209] 4. The cooling process is carried out according to T = α × T1. This step is the core of the algorithm. It gradually lowers the "temperature" of the system and reduces the probability of accepting a poor solution, thereby gradually stabilizing to the optimal solution.

[0210] 5. Finally, if the current system temperature T is not lower than the stop temperature T min , the algorithm will return to step c to continue iterating. If the stop temperature is reached or lower than the stop temperature, the algorithm stops and the current solution is used as the optimized solution, that is, the final installation position of the window frame unit.

[0211] Through this algorithm, the layout of window frame units can be systematically optimized to ensure that the position of each unit meets the design requirements while minimizing potential structural stress, thereby improving the safety and functionality of the overall building.

[0212] Furthermore, the properties of the window frame unit include:

[0213] The dimensions of the window frame unit, including the height, width and depth of the window frame;

[0214] The weight of the window frame unit;

[0215] The material of the window frame unit;

[0216] Coefficient of thermal expansion of the window frame unit;

[0217] Wind load carrying capacity of window frame units;

[0218] the soundproofing properties of the window frame units;

[0219] thermal insulation and insulation performance of window frame units;

[0220] Watertightness and airtightness of window frame units;

[0221] Fire resistance of window frame units.

[0222] The colour, shape and overall design style of the window frame unit.

[0223] In the rapid assembly method of modular curtain wall window structure, the window frame unit needs to consider multiple properties, which directly affect the functionality, durability and performance of the window frame unit in the overall building. The following is a detailed description of each property:

[0224] 1. The size of the window frame unit: including the height, width and depth of the window frame, these dimensions determine the space occupied and visual effect of the window frame. The selection of size needs to consider the spatial conditions of the installation location as well as the design aesthetics to ensure that the window frame unit can be seamlessly integrated into the overall style of the building.

[0225] 2. The weight of the window frame unit: It is important in terms of installation and structural safety. The weight affects the manpower and mechanical support required during installation, and is also related to the load-bearing calculation of the building structure.

[0226] 3. Material of the window frame unit: Choosing the right material is not only related to the aesthetics and cost of the window frame, but also directly affects its weather resistance, maintenance requirements and lifespan. Common materials include wood, metal (such as aluminum or steel), PVC, etc. Each material has its specific properties and applicable scenarios.

[0227] 4. Thermal expansion coefficient of the window frame unit: This property is crucial to assess the stability of the window frame under temperature changes. Different materials have different thermal expansion coefficients and their compatibility with other materials in the building should be considered when selecting to avoid structural stress caused by temperature changes.

[0228] 5. Wind load bearing capacity of window frame units: This is particularly important for high-rise buildings or areas with strong winds. It is necessary to ensure that the window frame units can withstand the impact of specific wind speeds to ensure the safety and stability of the structure.

[0229] 6. Sound insulation performance of window frame units: In a noisy environment, good sound insulation performance can improve indoor comfort and functionality, especially in residential and office buildings.

[0230] 7. Thermal insulation and heat preservation performance of window frame units: This is related to the energy efficiency of the building and the indoor temperature control. Efficient thermal insulation and heat preservation can significantly reduce energy consumption and is particularly critical for achieving green building standards.

[0231] 8. Waterproof and airtightness of window frame units: Ensuring that window frames can keep the interior dry and prevent water vapor intrusion under severe weather conditions is crucial to maintaining a comfortable indoor environment and preventing structural damage.

[0232] 9. Fire resistance of window frame units: In buildings with strict fire protection regulations, the fire resistance of window frames must meet relevant standards to delay the spread of fire and ensure the safety of occupants.

[0233] 10. Color, shape and overall design style of window frame units: These appearance attributes determine the coordination of window frame units with the overall style of the building and have an important impact on the visual appeal and cultural expression of the building.

[0234] Through careful consideration and optimization of these properties, modular curtain wall window structures can be designed and assembled that meet both functional requirements and aesthetic standards.

[0235] Step S106: According to the generated installation instructions, control the lifting equipment to lift the actual modular window frame unit to the corresponding wall opening; by adjusting the position of the lifting equipment, the connection structure on the modular window frame unit is matched and locked with the fixings on the wall opening to complete the installation of the modular window frame unit.

[0236] Step S106 involves moving the modular window frame unit from the preparation area to its predetermined installation position on the building through the lifting equipment, and ensuring that the connection structure of the window frame unit is correctly matched and locked with the fixings on the wall opening. This step is the actual execution stage in the installation process of the entire curtain wall window structure, which requires precise and careful operation to ensure the correct installation of the window frame and the safety of the overall structure.

[0237] First, the installation team will prepare the corresponding lifting equipment according to the installation instructions generated in step S105. This usually includes selecting a crane and slings that are suitable for the size and weight of the window frame unit. The installation team needs to ensure that all equipment is in good working condition and meets safety standards to prevent any possible accidents.

[0238] The technicians then positioned the lifting equipment to the window frame unit storage area and connected the slings or other lifting accessories to the pre-designed lifting points of the window frame unit. These lifting points were specially considered during the window frame design phase to ensure the balance and stability of the window frame during the lifting process.

[0239] After the lifting begins, the window frame unit will be lifted slowly and steadily and moved to the predetermined installation position. During the movement, the operator needs to constantly monitor the posture and speed of the window frame unit and adjust the operation of the lifting equipment to ensure that the window frame unit does not collide with other parts of the building. At the same time, the on-site commander will communicate with the lifting operator via radio and provide real-time position correction instructions to accurately control the position of the window frame unit.

[0240] When the window frame unit arrives at its installation location, the technician will make detailed position adjustments to ensure that the connection structure of the window frame unit is accurately aligned with the pre-installed fixings in the wall opening. Once the position adjustment is completed, the window frame unit will be locked to the fixings using bolts or other fastening devices. During the locking process, the technician will use tools such as torque wrenches to ensure that the fasteners are tightened to the specified torque to ensure the firmness of the connection and long-term structural safety.

[0241] Finally, after installation, technicians will conduct a final inspection, including a visual inspection and structural stability test, to confirm that the window frame unit is installed in the correct position, the connection structure is secure, and all lifting equipment has been completely evacuated. This inspection is an important step to ensure that the newly installed window frame unit can operate safely and meet building safety regulations.

[0242] Through these detailed operation steps, step S106 not only ensures the safe and accurate installation of the modular window frame unit, but also ensures the structural integrity and long-term performance of the curtain wall system of the entire building.
