The present invention carefully monitors various deviations of the reference surface, including elevation, flatness and verticality, by constructing elevation deviation coefficients, sag deviation coefficients and verticality deviation coefficients. This refined monitoring method can accurately locate specific construction points or grid monitoring areas, clearly identify the deviation sources that may affect the quality of curtain wall installation, and when it is detected that the deviation exceeds the set tolerance threshold, the system will automatically trigger the early warning mechanism, issue an alarm in time and mark abnormal construction points. Compared with the traditional method that relies on manual inspection, this system can detect potential problems in time during the installation process, avoiding the possibility of delays and later rework.

[0151] This example is explained in Example 2. Figure 1 :

[0152] The deviation control unit is used to generate a first reference surface repair strategy according to the first abnormal result report, including:

[0153] Extracting the elevation anomaly group in the grid monitoring area to generate a first repair strategy includes:

[0165] In this embodiment, the system greatly shortens the repair time by accurately controlling the thickness of the repair, the frequency of review and the maintenance time. Compared with the traditional manual repair method, the use of precise instruments for calibration and repair makes the entire repair process more efficient, reduces the possibility of repeated corrections, and thus saves the construction period and cost. A specific repair plan is provided for the deviation of the elevation, flatness and verticality of each construction point, and is monitored by precise tools such as laser levels to ensure the accuracy of each repair link. This refined repair management can ensure that the repair of each link meets the set standards and effectively avoids the overall curtain wall quality problems caused by single-point errors. By accurately repairing various deviations, especially in elevation, flatness and verticality, the system can eliminate potential construction errors and ensure the consistency and accuracy of the reference surface installation, thereby providing good basic support for subsequent construction steps (such as embedded parts installation, keel installation, panel installation, etc.). The present invention designs a repair method that adapts to different deviation conditions. For slight deviations, simple repair means are used, and for larger deviations, more complex processing methods are used, such as using hydraulic jacks to adjust the verticality of the vertical keel. By carrying out flexible repairs based on specific on-site conditions, the construction process was optimized to ensure the operability and effectiveness of the repair plan.

[0167] This example is an explanation of Example 1. Figure 1 :

[0168] Embedded parts are important components for fixing the curtain wall keel system, and the accuracy of their installation determines the stability and structural strength of the curtain wall. Traditional embedded parts installation mostly relies on manual measurement and manual adjustment, but this method lacks real-time monitoring and feedback mechanism, and is unable to detect potential installation deviations in a timely manner. In addition, the installation quality of embedded parts is also affected by factors such as verticality and pull-out force. Traditional methods often ignore the real-time monitoring of these factors, making it difficult to ensure the strength and firmness of embedded parts. Therefore, there are still major hidden dangers in the quality control of embedded parts installation, especially in some special environments. Unqualified quality of embedded parts may cause the keel system to loosen or fall off, affecting the overall stability of the curtain wall. Preferably, the embedded parts monitoring module includes an embedded parts installation monitoring unit and a second evaluation unit;

[0169] The embedded parts installation monitoring unit is used to monitor the position deviation, verticality and pull-out force of the embedded parts in real time during installation. Based on the monitoring data, the strength coefficient of the oth embedded part in the jth grid monitoring area of ​​the i-th horizontal partition is calculated by the following formula: ;

[0170]

[0171] in, , , Respectively represent the actual three-dimensional coordinates of the oth embedded part in the horizontal, longitudinal and vertical directions; , , Respectively represent the three-dimensional coordinates of the corresponding embedded parts in the design horizontal direction, longitudinal direction and vertical direction; , , Indicates the maximum allowable deviation value in the installation of the corresponding embedded parts;

Represents the actual pull-out force of the oth embedded part, measured by the force sensor. Indicates the corresponding design pull-out force; and Represent weights, , ,and ;

[0173] The second evaluation unit is used to preset a strength threshold W and calculate the strength coefficient of the oth embedded part in the jth grid monitoring area of ​​the i-th horizontal partition. Compare with the preset strength threshold W to obtain the embedded parts strength assessment results, including:

[0174] like , then it is determined that the installation strength of the oth embedded part in the grid monitoring area is qualified and no processing or adjustment is required;

[0175] like , it is determined that the installation strength of the oth embedded part in the grid monitoring area is unqualified, a second warning instruction is sent to the outside, and a second strategy is generated, including: using mortar or epoxy resin to reinforce the surrounding area of ​​the embedded part, gradually increasing the current reinforcement thickness of 2mm-10mm, until until.

[0176] In this embodiment, the traditional embedded parts installation method lacks real-time monitoring, often relying on manual measurement and manual adjustment, and cannot detect installation deviations in time. The present invention uses the embedded parts installation monitoring unit to monitor the key indicators such as position deviation, verticality and pull-out force during the installation of the embedded parts in real time, provides real-time data feedback, identifies potential installation problems in time, and avoids quality risks caused by manual errors or delays. The system calculates the strength coefficient of the embedded parts, compares the actual three-dimensional coordinates, embedding depth and pull-out force of the embedded parts with the design requirements, and conducts a comprehensive evaluation in combination with the allowable deviation value. This evaluation method based on precise data can accurately reflect the installation quality of the embedded parts, ensure that the installation of the embedded parts meets the design standards, and avoid quality problems caused by rough evaluation in traditional methods. For embedded parts with unqualified strength, the system automatically generates a second strategy, through reinforcement measures (such as mortar or epoxy resin reinforcement), and increases the reinforcement thickness layer by layer until it reaches the qualified standard. This automated repair scheme can accurately control the number and thickness of reinforcement layers, avoid the problems of over-repair or under-repair that may exist in traditional manual repair, and ensure the stability of the installation quality of embedded parts.

[0177] Example 5

[0178] This example is an explanation of Example 1. Figure 1 :

[0179] The installation of the keel is an important skeleton of the curtain wall system, and its installation stability directly affects the safety and appearance of the curtain wall panels. Traditional keel installation mostly relies on manual measurement and adjustment, and it is difficult to achieve real-time force monitoring and deformation analysis during the installation process. Since the connection points between the keel and the embedded parts are subject to large forces, traditional installation methods often ignore the real-time evaluation of the connection firmness and stress state, which may lead to deformation or loosening in the later stages of installation, thereby affecting the stability and safety of the overall curtain wall system. In addition, traditional technologies usually lack monitoring of vibration amplitude, resulting in the possibility that vibrations in the external environment may have a negative impact on the installation quality, and these problems are often difficult to trace and repair in the later stages. Preferably, the keel installation monitoring module includes a connector monitoring unit, a second associated unit, and a third evaluation unit;

[0180] The connection monitoring unit is used to monitor the stress state and deformation of the pth vertical keel component and the oth embedded component when connected, and to construct the stress distribution coefficient of the connection point. and deformation offset coefficient , while monitoring the vibration amplitude during installation and obtaining the vibration influence coefficient ;

[0181] The connection monitoring unit includes a force calculation unit, a deformation calculation unit and a vibration amplitude calculation unit;

[0182] The force calculation unit is used to monitor the force state when the pth vertical keel component is connected to the oth embedded part. The force distribution coefficient of the connection point between the pth vertical keel component and the oth embedded part is calculated by the following formula: :

[0183]

[0184] in, It represents the force value of the rth connection point, which is measured by the force sensor and reflects the force value when the pth vertical keel component is connected to the oth embedded part. It represents the vertical distance between the rth connection point and the reference point. represents the maximum connection point distance; D represents the total number of connection points between the pth vertical keel component and the oth embedded part;

[0185] The deformation calculation unit is used to monitor the deformation of the pth vertical keel component when it is connected to the oth embedded part. The deformation offset coefficient of the pth vertical keel component and the oth embedded part is calculated by the following formula: :

[0186]

[0187] in, Represents the displacement deviation value of the rth connection point relative to the reference point, represents the maximum deformation deviation value of the ith connection point relative to the reference point; D represents the total number of connection points between the pth vertical keel component and the oth embedded part;

[0188] The vibration amplitude calculation unit is used to monitor the vibration amplitude during installation and calculate the vibration influence coefficient of the pth vertical keel component and the oth embedded component by the following formula: ;

[0189]

[0190] in, It represents the amplitude of the cth vibration point between the pth vertical keel component and the oth embedded part, which is measured by the vibration sensor. It represents the vibration frequency of the cth vibration point in the pth vertical keel component and the oth embedded part, which is obtained by measuring with a vibration sensor. It represents the relative angle between the pth vertical keel component and the center line of the oth embedded component, which is measured by the angle sensor. Indicates the maximum vibration amplitude, represents the maximum vibration frequency; V represents the total number of vibration points.

[0191] The second associated unit is used to calculate the force distribution coefficient of the connection point between the pth vertical keel component and the oth embedded part. , deformation offset coefficient and vibration influence coefficient After dimensionless processing, the connection firmness coefficient between the pth vertical keel component and the oth embedded part is calculated by the following formula: :

[0192]

[0193] In the formula, , and They represent the force distribution coefficients of the connection points between the pth vertical keel component and the oth embedded part. , deformation offset coefficient and vibration influence coefficient The weight of , , ,and ;

[0194] The third evaluation unit is used to preset a firm threshold T and calculate the connection firmness coefficient between the p-th vertical keel component and the o-th embedded component. Compare with the firmness threshold T to obtain a third evaluation result, including:

[0195] like , it is determined that the connection between the pth vertical keel component and the oth embedded component is firm and does not need to be processed or adjusted;

[0196] like , it is determined that the connection between the pth vertical keel component and the oth embedded component is not firm, a third warning instruction is sent to the outside, and a third strategy is generated, including: adding connectors with a number V*10%-20% of the total number of connection points between the pth vertical keel component and the oth embedded component at the connection between the pth vertical keel component and the oth embedded component, the connectors including bolts, welding points, reinforcing ribs or support plates; until until.

[0197] In this embodiment, the traditional keel installation method fails to effectively monitor the stress condition of the connection point, while the present invention monitors the stress state of the connection point between the vertical keel component and the embedded part in real time through the force calculation unit, uses the force sensor to accurately obtain the force value, and combines the distance and the total number of connection points to evaluate the force distribution. This real-time monitoring can timely discover problems such as uneven force, overload or insufficient force, avoiding installation problems caused by the lag of force analysis in the traditional method. This system monitors the deformation of the connection point in real time through the deformation calculation unit and calculates the deformation offset coefficient. By comparing the displacement deviation value of the connection point with the maximum deformation deviation value, the deformation condition during the keel installation process can be effectively evaluated, and the potential risks caused by excessive deformation can be discovered in advance. This precise deformation monitoring can avoid looseness or instability caused by deformation in the later stage of installation, thereby improving the accuracy and safety of installation. This embodiment introduces a vibration amplitude calculation unit, which calculates the vibration influence coefficient by monitoring the vibration amplitude during the installation process. By considering the influence of the amplitude, frequency and relative angle of the vibration point, the influence of the external environment on the installation quality can be fully analyzed. This is necessary to ensure that the keel installed in a vibration environment can withstand external vibration interference. This system uses the second associated unit to make the force distribution coefficient, deformation offset coefficient and vibration influence coefficient dimensionless, and then calculates the connection firmness coefficient. This comprehensive evaluation method combines multiple key factors, and can more comprehensively and accurately evaluate the firmness of the connection point, avoiding the limitation of the traditional method that relies on only one factor to judge, and ensuring the stability and safety of the connection between the keel and the embedded parts. When it is found that the connection point is not firm enough, the third evaluation unit automatically generates a repair strategy according to the preset firmness threshold, sends an early warning to the outside and proposes specific repair measures. By adding additional connectors (such as bolts, welding points, reinforcing ribs or support plates, etc.), the firmness of the connection point can be effectively improved. This intelligent repair solution not only ensures the improvement of the connection firmness, but also avoids the lag of manual adjustment, and improves the construction efficiency and quality.

[0200] Panel installation is the final step of curtain wall installation. To ensure the correct installation of the panel, it is necessary not only to ensure the precise control of physical parameters such as joint width and angle deviation, but also to ensure the air tightness and water tightness of the panel after installation. However, in the traditional panel installation process, the adjustment of the width and angle of the joint mostly relies on manual operation and experience, and there is a certain error space. The detection of air tightness and water tightness performance usually also relies on post-inspection and cannot be monitored and adjusted in real time. Once there is a problem with the installation quality of the panel, it will directly affect the comfort and energy saving of the building, and the repair process is usually complicated and costly.

[0213] In this embodiment, the panel monitoring unit is a technical solution for controlling and monitoring the installation quality of curtain wall panels. Through the panel monitoring unit, the third associated unit and the fourth evaluation unit, key parameters in panel installation (such as joint width, angle deviation, air tightness and water tightness) can be monitored and adjusted in real time, thereby improving installation quality, reducing later maintenance costs and ensuring the comfort and energy saving of the building.

The use of three-dimensional laser scanning technology to obtain spatial data can achieve accurate geometric deviation detection, and perform immediate warning and repair based on the preset deviation threshold. Real-time monitoring of each construction stage, such as the installation quality of embedded parts, the stress state of vertical keel connections, and the joint deviation of panel installation, ensures the stability, air tightness and water tightness of the building curtain wall, and avoids later problems caused by human errors in traditional construction.
