Description

Technical Field

[0001] The invention relates to the technical field of curtain wall sealing performance monitoring, and in particular to a building curtain wall sealing performance monitoring system. Background Art

[0002] The sealing performance of curtain walls is related to building safety and comfort. Traditional detection methods have limitations, such as water spray tests on vulnerable buildings. In order to accurately, comprehensively and non-destructively monitor the sealing performance of curtain walls and adapt to complex environments and long-term use needs, relevant monitoring systems have come into being.

[0003] Prior art, such as the invention patent application with announcement number CN115307839A, discloses a curtain wall structure sealing detection system and detection method, including: a single chip microcomputer installed in the closed cavity; an air pressure sensor installed in the closed cavity and connected to the single chip microcomputer, used to detect the actual pressure value Preal in the closed cavity; a judgment unit connected to each of the single chip microcomputers and located outside the closed cavity, used to analyze the actual pressure value Preal data of each of the closed cavities and judge whether the sealing of each of the closed cavities fails; a display unit connected to the judgment unit and located outside the closed cavity, used to display the judgment result of the sealing of each of the closed cavities. Real-time detection of the connection of each curtain wall panel can more quickly and accurately locate the location of the sealing failure on the curtain wall structure, avoiding the problem that the water spray test easily causes damage to the building.

[0004] With respect to the above scheme, there are at least the following technical problems: 1. The above scheme lacks detection and analysis of the degree of aging of the sealing material, which will result in the inability to predict in advance the curtain wall sealing problems caused by the aging of the sealing material. During long-term use, the sealing material is affected by environmental factors such as ultraviolet rays, temperature changes and humidity, and its waterproof sealing performance will decline, such as the expansion of micro cracks, loss of chemical components and adhesion attenuation. The above scheme only focuses on detecting the actual pressure value in the closed cavity through the air pressure sensor to determine whether the airtightness has failed, and does not monitor the aging condition of the sealing material itself. As a result, when the sealing material has begun to age but has not yet caused a significant change in air pressure, it is impossible to detect potential risks in time, which will cause the curtain wall sealing to suddenly deteriorate without any warning, increasing the cost and difficulty of maintenance.

[0005] 2. The above scheme lacks a multi-parameter comprehensive test and evaluation of the waterproof sealing performance, which will lead to an incomplete and inaccurate judgment of the curtain wall's waterproof sealing performance. It only relies on the pressure value detected by the air pressure sensor to judge the airtightness, and cannot deeply understand the actual effect of the curtain wall's waterproof sealing under different working conditions. For example, during rainfall, factors such as the penetration depth of rainwater and the change in the contact angle of water droplets on the curtain wall surface are closely related to the waterproof performance.

[0006] 3. The above scheme lacks consideration of the evaluation of drainage performance, which will make it impossible to determine whether the curtain wall drainage system is operating normally and its impact on the waterproof sealing performance. The above scheme does not monitor these drainage performance parameters. When encountering heavy rainfall or partial blockage of the drainage system, it is impossible to timely know the hidden dangers of water accumulation caused by poor drainage. Water accumulation will increase the pressure load of the curtain wall and destroy the sealing structure. Even the originally well-sealed parts will leak due to long-term water accumulation, thereby endangering the safety and normal use of the building. Summary of the invention

[0007] The purpose of the present invention is to provide a building curtain wall sealing performance monitoring system, which solves the problems existing in the background technology.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a building curtain wall sealing performance monitoring system, including: a curtain wall sealing material analysis module, which is used to divide a specified building curtain wall into various monitoring areas and set each periodic monitoring time point, and then evaluate whether the aging degree of the sealing material in each monitoring area of ​​the specified building curtain wall at each periodic monitoring time point meets the sealing requirements.

[0009] The waterproof sealing performance test module is used to perform a waterproof sealing performance test on a monitored area when the aging degree of the corresponding sealing material of a monitored area does not meet the sealing requirements, so as to evaluate whether the waterproof sealing performance of the monitored area meets the waterproof sealing requirements.

[0010] The curtain wall waterproof performance analysis module is used to calculate the waterproof performance evaluation coefficient of each collection point in each monitoring area corresponding to each real-time monitoring time point when the aging degree of the corresponding sealing material in each monitoring area meets the requirements and the rainfall is greater than or equal to the set rainfall threshold.

[0011] The curtain wall drainage performance analysis module is used to calculate the drainage performance evaluation coefficient corresponding to the specified building curtain wall at each real-time monitoring time point when the aging degree of the corresponding sealing material in each monitoring area meets the requirements.

[0012] The comprehensive waterproof sealing performance evaluation module is used to comprehensively evaluate whether the waterproof sealing performance of the specified building curtain wall corresponding to each monitoring area at each real-time monitoring time point meets the waterproof sealing requirements.

[0013] The beneficial effects of the present invention are as follows: 1. A building curtain wall sealing performance monitoring system provided by an embodiment of the present invention, during the construction process of the curtain wall sealing performance monitoring system, by dividing the designated building curtain wall into various monitoring areas and setting periodic monitoring time points, it is helpful to accurately locate the sealing material aging problem area and timely discover potential hidden dangers, and set collection points at the sealing material connection points of each monitoring area. Through multi-parameter and multi-means monitoring methods, it is helpful to fully and deeply understand the aging condition of the sealing material. For example, in the curtain wall area that is long-term exposed to ultraviolet radiation and temperature changes, microcracks will first occur at the weak points of the sealing material. Through accurate monitoring of microcrack-related parameters, it is helpful to detect the downward trend of the sealing material performance at an early stage, plan maintenance or replacement plans in advance, and avoid serious problems such as large-area leakage or air infiltration caused by aging of the sealing material.

[0014] 2. In the waterproof sealing performance test process of the embodiment of the present invention, when the aging degree of the sealing material in the monitored area does not meet the requirements, high-precision pressure sensors and humidity sensors are set at relevant collection points, and the sealing cover is used to increase the pressure and record the pressure and humidity values. Evaluation is performed with the help of the waterproof sealing performance discriminant formula, which is conducive to accurately judging whether the waterproof sealing performance of the area meets the standards.

[0015] 3. In the process of analyzing the waterproof performance of the curtain wall according to the embodiment of the present invention, when the aging degree of the sealing material meets the requirements and the rainfall reaches the threshold, the waterproof performance evaluation coefficient is calculated by collecting the waterproof performance parameters, which is beneficial to dynamically evaluate the waterproof performance of the curtain wall in a rainfall environment. When rainwater contacts the surface of the curtain wall, the size of the water droplet contact angle reflects the hydrophobicity of the curtain wall surface, and the contact angle change rate reflects the change of hydrophobicity over time or in the environment. If the contact angle decreases rapidly, it means that rainwater spreads and penetrates on the surface of the curtain wall, and the penetration depth growth rate is directly related to the degree of rainwater intrusion into the interior of the curtain wall, which helps to timely discover the downward trend of waterproof performance and make preparations for protection or repair in advance.

[0016] 4. In the process of curtain wall drainage performance analysis, the embodiment of the present invention collects drainage performance parameters to calculate the drainage performance evaluation coefficient, which is conducive to a comprehensive evaluation of the working status of the drainage system. The drainage volume change rate reflects the drainage efficiency of the drainage system in different periods of time, the drainage uniformity reflects the balance of drainage in different areas of the curtain wall, and the pressure change rate takes into account the pressure factor in the drainage process. The calculation method of placing the pressure change rate in the denominator effectively avoids misleading the drainage performance evaluation due to abnormal pressure changes, making the drainage performance evaluation more scientific and accurate, and further improving the overall waterproof sealing performance of the curtain wall.

[0017] 5. In the comprehensive evaluation process, the embodiment of the present invention calculates the comprehensive waterproof performance coefficient, which is conducive to comprehensively and accurately judging the waterproof sealing performance of the curtain wall in different time periods and regions. Each periodic monitoring time point conducts long-term monitoring on the aging of the sealing material, while the real-time monitoring time point focuses on the waterproof and drainage performance evaluation under specific working conditions such as rainfall. The comprehensive evaluation method comprehensively considers the mutual influence of various factors, provides a scientific basis for the maintenance and management of the curtain wall, ensures that the curtain wall always maintains good waterproof sealing performance throughout the entire service life, and ensures the safety and normal use of the building.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 As shown, the present invention provides a building curtain wall sealing performance monitoring system, the method comprising: a curtain wall sealing material analysis module, a waterproof sealing performance testing module, a curtain wall waterproof performance analysis module, a curtain wall drainage performance analysis module, a comprehensive waterproof sealing performance evaluation module and a database.

[0022] The curtain wall sealing material analysis module is connected to the waterproof sealing performance testing module and the database respectively; the waterproof sealing performance testing module is connected to the curtain wall waterproof performance analysis module, the curtain wall drainage performance analysis module and the database respectively; the curtain wall waterproof performance analysis module is connected to the comprehensive waterproof sealing performance evaluation module; and the curtain wall drainage performance analysis module is connected to the comprehensive waterproof sealing performance evaluation module.

[0023] The curtain wall sealing material analysis module is used to divide the designated building curtain wall into various monitoring areas and set each periodic monitoring time point, and then evaluate whether the aging degree of the sealing material in each monitoring area of ​​the designated building curtain wall at each periodic monitoring time point meets the sealing requirements.

[0024] In a specific embodiment, the evaluation of whether the degree of aging of the sealing materials in each monitoring area of ​​the specified building curtain wall at each periodic monitoring time point meets the sealing requirements is as follows: each collection point is set at the sealing material connection of each monitoring area of ​​the specified building curtain wall, and then the sealing material aging parameters of each collection point in each monitoring area corresponding to each periodic monitoring time point are obtained, and the sealing material aging parameters include microcrack growth rate, chemical component loss rate and adhesion attenuation coefficient, and then the sealing material aging coefficient corresponding to each monitoring area at each periodic monitoring time point is calculated, and the standard control sealing material aging coefficient threshold value corresponding to the sealing material aging degree is obtained from the database. If the sealing material aging coefficient corresponding to a certain monitoring area at a certain periodic monitoring time point is greater than or equal to the standard control sealing material aging coefficient threshold value, it indicates that the sealing material aging degree corresponding to the monitoring area at the periodic monitoring time point does not meet the sealing requirements, otherwise, it indicates that the sealing material aging degree meets the sealing requirements.

[0025] It should be noted that the sealing material joints include collection points set at the bonding points between the glass panel and the sealant of the glass curtain wall and at the contact points between the sealing strip and the aluminum alloy frame.

[0026] In a specific embodiment, the aging parameters of the sealing material corresponding to each collection point in each monitoring area at each periodic monitoring time point are obtained by using a microscope device to obtain the microcrack length, microcrack width and microcrack number of each collection point in each monitoring area corresponding to each periodic monitoring time point, and are recorded as , and , Number the monitoring time points for each cycle. , is the total number of periodic monitoring time points, is a positive integer, Number each monitoring area. , is the total number of monitored areas, is a positive integer, Number each collection point. , is the total number corresponding to the sample area, is a positive integer, and the initial microcrack length, initial microcrack width and initial microcrack number of each sampling point in each monitoring area are obtained from the database and recorded as , and , and then through the calculation formula: , and obtain the microcrack growth rate of each sampling point in each monitoring area corresponding to each period monitoring time point , , , They are microcrack length weight factor, microcrack width weight factor, and microcrack number weight factor respectively.

[0027] The initial chemical component content of each collection point in each monitoring area is obtained from the database, and the chemical component content of each collection point in each monitoring area corresponding to each periodic monitoring time point is obtained through micro-sampling tools, and then the chemical component loss rate of each collection point in each monitoring area corresponding to each periodic monitoring time point is calculated. The contact area between the sealing material and the sealing bonding substrate corresponding to each sampling point in each monitoring area at each periodic monitoring time point is prepared into each sample by cutting and grinding. The adhesion force corresponding to the sample at each sampling point in each monitoring area is obtained by using an adhesion tester, which is recorded as , the initial adhesion force of each collection point in each monitoring area is obtained from the database and recorded as ,Will Divide by , thus obtaining the adhesion attenuation coefficient of each collection point in each monitoring area at each period monitoring time point .

[0028] It should be noted that , , The values ​​of are all greater than and less than The process of setting the weight factor of microcrack length, microcrack width and microcrack number is as follows: for example, firstly, a large number of curtain wall sealing material samples of the same type are subjected to simulated aging tests, and then the influence of the changes in the length, width and number of microcracks of each sample on the sealing performance is obtained. Although the number of microcracks in a certain sample is small, the length is long and the width is large, resulting in serious sealing failure, the weight factors of the length and width of the microcracks are increased. On the contrary, if the number of microcracks in another sample is large but they are short and narrow, and the influence on the sealing performance is small, the weight factor value is reduced. Through statistical analysis of numerous test data and expert experience, the weight factor of microcrack length, the weight factor of microcrack width and the weight factor of microcrack number are comprehensively determined to be 0.4, 0.4 and 0.2, so as to accurately evaluate the influence of microcrack growth rate on the aging of sealing materials.

[0029] It should also be noted that the common chemical components of sealing materials are such as the silicon-oxygen bond components in silicone polymers, and the micro-sampling tools include micro-scrapers and micro-needles. The process of calculating the chemical component loss rate of each sampling point in each monitoring area corresponding to each periodic monitoring time point is the same as the process of calculating the microcrack propagation rate of each sampling point in each monitoring area corresponding to each periodic monitoring time point, and will not be elaborated on here. The sealing bonding substrate contact area refers to the base material part of the building curtain wall with which the sealing material directly contacts and produces adhesion.

[0030] In a specific embodiment, the calculation is performed to obtain the sealing material aging coefficient corresponding to each monitoring area at each periodic monitoring time point. The specific process is as follows: by the calculation formula: , and obtain the sealing material aging coefficient corresponding to each monitoring area at each periodic monitoring time point , , , They are respectively the weight factor corresponding to the set microcrack growth rate, the weight factor corresponding to the chemical component loss rate, and the weight factor corresponding to the adhesion attenuation coefficient.

[0031] It should be noted that , , The values ​​of are all greater than and less than , , , The setting process , , The setting process is the same as , so I will not go into details here.

[0032] The waterproof sealing performance test module is used to perform a waterproof sealing performance test on a monitored area when the aging degree of the corresponding sealing material of a monitored area does not meet the sealing requirements, so as to evaluate whether the waterproof sealing performance of the monitored area meets the waterproof sealing requirements.

[0033] In a specific embodiment, the specific process of determining whether the waterproof sealing performance of the monitored area meets the waterproof sealing requirements is as follows: high-precision pressure sensors and humidity sensors are set at each collection point in the monitored area where the aging degree of the sealing material does not meet the sealing requirements, and each sealing cover is used to cover and seal each collection point in the monitored area, and according to the set pressurization interval, the pressure in each sealing cover is increased to a set pressure value through a pipeline, and a data acquisition instrument is used to record the pressure value and humidity value at the set recording time interval, so as to obtain the corresponding pressure difference and humidity difference in each recording time interval, which are recorded as and , Number each recording time interval, , To record the total number of time intervals, is a positive integer, and the evaluation result of whether the waterproof sealing performance of the monitored area meets the waterproof sealing requirements is recorded as , Contains values and ,like If When , it indicates that the waterproof sealing performance of the monitored area does not meet the waterproof sealing requirements, and the corresponding standard pressure difference and standard humidity difference within the set recording time interval are obtained from the database and recorded as and , through the waterproof sealing performance discriminant formula: , and obtain the evaluation result of whether the waterproof sealing performance of the monitored area meets the waterproof sealing requirements ,in Represents logic and relationship, Indicates logic or relationship.

[0034] It should be noted that the pressure value collected by the data acquisition instrument at the beginning of a certain recording time interval is subtracted from the pressure value collected at the end of the recording time interval, so as to obtain the corresponding pressure difference within each recording time interval, and the humidity value collected by the data acquisition instrument at the end of a certain recording time interval is subtracted from the humidity value collected at the beginning of the recording time interval, so as to obtain the corresponding humidity difference within each recording time interval.

[0035] In the waterproof sealing performance test process of the embodiment of the present invention, when the aging degree of the sealing material in the monitored area does not meet the requirements, high-precision pressure sensors and humidity sensors are set at relevant collection points, and the sealing cover is used to increase the pressure and record the pressure and humidity values. Evaluation is performed with the help of the waterproof sealing performance discriminant formula, which is conducive to accurately judging whether the waterproof sealing performance of the area meets the standards.

[0036] The curtain wall waterproof performance analysis module is used to calculate the waterproof performance evaluation coefficient of each collection point in each monitoring area corresponding to each real-time monitoring time point when the aging degree of the corresponding sealing material in each monitoring area meets the requirements and the rainfall is greater than or equal to the set rainfall threshold.

[0037] In a specific embodiment, the waterproof performance evaluation coefficient of each collection point in each monitoring area corresponding to each real-time monitoring time point is calculated, and the specific process is as follows: the waterproof performance parameters of each collection point in each monitoring area corresponding to each real-time monitoring time point set are collected, and the waterproof performance parameters include the change rate of the water drop contact angle and the penetration depth growth rate, and are recorded as , , Number each real-time monitoring time point, , To monitor the total number of time points in real time, is a positive integer, and then calculated by the formula: , and obtain the waterproof performance evaluation coefficient of each collection point in each monitoring area at each real-time monitoring time point ,in and They are the weight factor corresponding to the set water drop contact angle change rate and the weight factor corresponding to the penetration depth growth rate.

[0038] It should be noted that and The values ​​of are all greater than and less than , and The setting process of , , The setting process is the same as , so I will not go into details here.

[0039] It should also be noted that, taking glass curtain wall sealant as an example, for the change rate of water droplet contact angle, at each real-time monitoring time point, a contact angle meter is used to measure the surface of the sealing material at each collection point in each monitoring area, and the contact angle formed between the initial water droplets and the material surface at each collection point in each monitoring area is recorded. The ratio of the difference between the before and after contact angles to the initial contact angle is calculated to obtain the change rate of water droplet contact angle at each collection point in each monitoring area corresponding to each real-time monitoring time point. The collection process of the penetration depth growth rate is the same as the collection process of the water droplet contact angle change rate, which will not be elaborated here.

[0040] In the process of analyzing the waterproof performance of the curtain wall in the embodiment of the present invention, when the aging degree of the sealing material meets the requirements and the rainfall reaches the threshold, the waterproof performance evaluation coefficient is calculated by collecting the waterproof performance parameters, which is beneficial to dynamically evaluate the waterproof performance of the curtain wall in a rainfall environment. When rainwater contacts the surface of the curtain wall, the size of the water droplet contact angle reflects the hydrophobicity of the curtain wall surface, and the contact angle change rate reflects the change of hydrophobicity over time or in the environment. If the contact angle decreases rapidly, it means that rainwater spreads and penetrates on the surface of the curtain wall, and the penetration depth growth rate is directly related to the degree of rainwater intrusion into the interior of the curtain wall, which helps to timely discover the downward trend of waterproof performance and make preparations for protection or repair in advance.

[0041] The curtain wall drainage performance analysis module is used to calculate the drainage performance evaluation coefficient corresponding to the specified building curtain wall at each real-time monitoring time point when the aging degree of the corresponding sealing material in each monitoring area meets the requirements.

[0042] In a specific embodiment, the drainage performance evaluation coefficient corresponding to each real-time monitoring time point of the specified building curtain wall is calculated, and the specific process is as follows: by collecting the drainage performance parameters corresponding to each real-time monitoring time point, the drainage performance parameters include the drainage volume change rate, drainage uniformity and pressure change rate, and are recorded as , and , and then through the calculation formula: , get the drainage performance evaluation coefficient corresponding to the specified building curtain wall at each real-time monitoring time point ,in , , They are respectively the weight factor corresponding to the set displacement change rate, the weight factor corresponding to the drainage uniformity, and the weight factor corresponding to the pressure change rate.

[0043] It should be noted that , , The values ​​of are all greater than and less than , , , The setting process of , , The setting process is the same as , so I will not go into details here.

[0044] It should also be noted that drainage uniformity is divided into Levels, from arrive , is a positive integer, and the higher the level, the more uniform it is. In this way, the drainage uniformity corresponding to each real-time monitoring time point is obtained. For example, when observing the drainage of the curtain wall, if it is found that more than 60%-70% of the drainage is concentrated in a local area that only accounts for 10%-20% of the entire drainage area, the drainage is considered to be uneven. For example, in a rectangular curtain wall drainage area, water flows out from the short side of one side in large quantities, while there is only a small amount of water flow or almost no water flow in other long side areas. This situation meets the characteristics of uneven drainage. If the drainage is seriously uneven, the drainage uniformity is assigned to , through the formula , the drainage uniformity is , so as to obtain the drainage uniformity corresponding to each real-time monitoring time point The collection process of the displacement change rate and the pressure change rate is the same as the acquisition process of the water drop contact angle change rate, which will not be elaborated here.

[0045] It should also be noted that the pressure change rate is placed in the denominator in order to balance the influence of different factors in the drainage performance evaluation. For example, in the drainage process, the drainage volume change rate and drainage uniformity are factors that are expected to positively affect the drainage performance. It means that a reasonable increase in the drainage volume change rate and good drainage uniformity mean better drainage performance. Within a certain range of the pressure change rate, appropriate pressure changes are conducive to drainage, but large or small pressure changes will have an adverse effect on drainage. Large pressure changes will cause the drainage system to be impacted, and problems such as leakage or poor drainage will occur. Small pressure changes mean insufficient drainage power. By placing the pressure change rate in the denominator, when the pressure change rate increases or decreases, the value of the denominator will change accordingly, thereby inhibiting the entire drainage performance evaluation coefficient.

[0046] In the process of curtain wall drainage performance analysis, the embodiment of the present invention collects drainage performance parameters to calculate the drainage performance evaluation coefficient, which is conducive to comprehensively evaluating the working status of the drainage system. The drainage volume change rate reflects the drainage efficiency of the drainage system in different time periods, the drainage uniformity reflects the balance of drainage in different areas of the curtain wall, and the pressure change rate takes into account the pressure factor in the drainage process. The calculation method of placing the pressure change rate in the denominator effectively avoids misleading the drainage performance evaluation due to abnormal pressure changes, makes the drainage performance evaluation more scientific and accurate, and further improves the overall waterproof sealing performance of the curtain wall.

[0047] The comprehensive waterproof sealing performance evaluation module is used to comprehensively evaluate whether the waterproof sealing performance of the specified building curtain wall corresponding to each monitoring area at each real-time monitoring time point meets the waterproof sealing requirements.

[0048] In a specific embodiment, the comprehensive evaluation of whether the waterproof sealing performance of each monitoring area corresponding to the designated building curtain wall at each real-time monitoring time point meets the waterproof sealing requirements is as follows: according to the sealing material aging coefficient corresponding to each monitoring area at each periodic monitoring time point, the waterproof performance evaluation coefficient corresponding to each monitoring area at each real-time monitoring time point, and the drainage performance evaluation coefficient corresponding to the designated building curtain wall at each real-time monitoring time point, and by analyzing the relationship between each periodic monitoring time point and each real-time monitoring time point, the comprehensive waterproof performance coefficient of the designated building curtain wall corresponding to each monitoring area at each real-time monitoring time point is calculated, which is recorded as , Contains values and ,like , it means that the specified building curtain wall is in The real-time monitoring time point corresponds to The waterproof sealing performance of each monitoring area does not meet the waterproof sealing requirements. , it means that the specified building curtain wall is in The real-time monitoring time point corresponds to The waterproof sealing performance of each monitoring area meets the waterproof sealing requirements, so as to obtain whether the waterproof sealing performance of each monitoring area of ​​the specified building curtain wall at each real-time monitoring time point meets the waterproof sealing requirements.

[0049] In a specific embodiment, the relationship between each periodic monitoring time point and each real-time monitoring time point is analyzed, and the specific process is as follows: the time interval corresponding to each periodic monitoring time point is less than the time interval corresponding to each real-time monitoring time point. The real-time monitoring time point corresponds to the waterproof performance evaluation coefficient of each monitoring area and the designated building curtain wall at the When calculating the comprehensive waterproof performance coefficient of each monitoring area corresponding to each real-time monitoring time point, the drainage performance evaluation coefficient corresponding to each real-time monitoring time point of the specified building curtain wall will be used together with the first The aging coefficient of the sealing material in each monitoring area corresponding to the periodic monitoring time point closest to the real-time monitoring time point is calculated.

[0050] It should be noted that, for example, when the real-time monitoring time point is monitored to the 20th real-time monitoring time point, and the periodic monitoring time point is now monitored to the 10th periodic monitoring time point, but the time difference between the 20th real-time monitoring time point and the 9th periodic monitoring time point is 2 minutes, and the time difference between the 20th real-time monitoring time point and the 10th periodic monitoring time point is 3 minutes, then the waterproof performance evaluation coefficient and drainage performance evaluation coefficient corresponding to the 20th real-time monitoring time point, and the sealing material aging coefficient corresponding to the 9th periodic monitoring time point are used to calculate the comprehensive waterproof performance coefficient.

[0051] In a specific embodiment, the calculation obtains the comprehensive waterproof performance coefficient of each monitoring area of ​​the specified building curtain wall at each real-time monitoring time point, and the specific process is as follows: by calculating the formula: , get the comprehensive waterproof performance coefficient of the specified building curtain wall corresponding to each monitoring area at each real-time monitoring time point ,in , , They are respectively the weight factor corresponding to the set sealing material aging coefficient, the weight factor corresponding to the waterproof performance evaluation coefficient, and the weight factor corresponding to the drainage performance evaluation coefficient.

[0052] It should be noted that , , The values ​​of are all greater than and less than , , , The setting process of , , The setting process is the same as , so I will not go into details here.

[0053] The database is used to store the standard control sealing material aging coefficient threshold value corresponding to the aging degree of the sealing material, and also stores the initial microcrack length, initial microcrack width and initial microcrack number of each collection point in each monitoring area, and also stores the initial chemical component content of each collection point in each monitoring area, and also stores the initial adhesion of each collection point in each monitoring area, and also stores the corresponding standard pressure difference and standard humidity difference within the set recording time interval.

[0054] In the comprehensive evaluation process, the embodiment of the present invention calculates the comprehensive waterproof performance coefficient, which is conducive to comprehensively and accurately judging the waterproof sealing performance of the curtain wall in different time periods and areas from the overall perspective. The aging of the sealing material is monitored for a long time at each periodic monitoring time point, while the real-time monitoring time point focuses on the waterproof and drainage performance evaluation under specific working conditions such as rainfall. The comprehensive evaluation method comprehensively considers the mutual influence of various factors, provides a scientific basis for the maintenance and management of the curtain wall, ensures that the curtain wall always maintains good waterproof sealing performance throughout the entire service life, and ensures the safety and normal use of the building.

[0055] A building curtain wall sealing performance monitoring system provided by an embodiment of the present invention, during the construction process of the curtain wall sealing performance monitoring system, by dividing the designated building curtain wall into various monitoring areas and setting periodic monitoring time points, it is helpful to accurately locate the sealing material aging problem area and timely discover potential hidden dangers, and set a collection point at the sealing material connection of each monitoring area. Through a multi-parameter and multi-means monitoring method, it is helpful to fully and deeply understand the aging condition of the sealing material. For example, in the curtain wall area that is long-term exposed to ultraviolet radiation and temperature changes, microcracks will first be generated at the weak points of the sealing material. Through accurate monitoring of microcrack-related parameters, it is helpful to detect the downward trend of the sealing material performance at an early stage, plan maintenance or replacement plans in advance, and avoid serious problems such as large-area leakage or air infiltration caused by aging of the sealing material.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined in this specification, they should all fall within the protection scope of the present invention.
