Description

Technical Field

[0001] This invention relates to an online construction monitoring device and method, and more particularly to an online construction monitoring device and method for the concrete top layer of a high-rise building. Background Technology

[0002] In high-rise buildings, to ensure overall structural strength, a concrete top layer needs to be constructed. To guarantee the quality of this top layer construction, an online monitoring device for the concrete top layer is crucial. Currently, in large-volume concrete construction, top layer quality control mainly relies on manual experience and single-parameter testing methods, such as using a penetration resistance meter to determine the setting state, a thermometer to monitor temperature rise, or core sampling to assess uniformity. Existing technologies also include monitoring devices based on single sensors (such as temperature or humidity) that can automatically collect local data. However, these methods have significant limitations: first, they cannot reflect the uniformity of pouring, vibration effect, and curing status in real time and from multiple dimensions; second, the data is scattered and lacks integrated analysis, making it difficult to comprehensively assess construction quality; and third, they rely on manual judgment and intervention, resulting in delayed early warnings and an inability to achieve precise process control, thus affecting the quality controllability and management efficiency of concrete top-layer construction. This invention utilizes the technical feature of constructing the concrete top layer of a high-rise building while maintaining an online parameter acquisition and monitoring database. It effectively explores and studies the technical problem that the quality control of the top layer in the construction of large-volume concrete mainly relies on manual experience and single-parameter detection methods.

[0036] This invention designs an online monitoring method for the construction of the concrete top layer of a high-rise building. The steps are as follows: a resistivity / dielectric constant sensor, a vibration sensor, a temperature and humidity sensor, and an ultrasonic transmitter / receiver are installed on the concrete top layer during construction using a cylindrical beam frame. The resistivity / dielectric constant sensor and the vibration sensor enable online monitoring of parameters during the concrete pouring process. The temperature and humidity sensor and the ultrasonic transmitter / receiver enable online monitoring of parameters during the concrete pouring and curing process. This allows the construction of the concrete top layer of the high-rise building to be carried out while the backup database is obtained through online parameter acquisition and monitoring.

[0037] The technical effect of the above technical solution is that it highlights the technical characteristics of constructing the concrete top layer of high-rise buildings while in a state of online parameter acquisition and monitoring with a backup database, and introduces its application in the technical field of online monitoring methods for the construction of concrete top layers of high-rise buildings.

[0038] This invention comprises the following steps: When the controller inputs a signal to the electric push rod part I, causing it to be in a working state, it drives the U-shaped toothed body of the moving seat part I to move in the receiving groove V, causing the mounting seat part and mounting plate part to move up and down in the cylinder part I, adjusting the height position of the resistivity / dielectric constant sensor and the vibration sensor; when the controller inputs a signal to the electric push rod part II, causing it to be in a working state, it drives the moving seat part II to move in the receiving groove III, causing the cylinder part II to move up and down on the cylinder part I, adjusting the height position of the temperature and humidity sensor; when the controller inputs a signal to the camera, causing it to be in a working state, it picks up the concrete top layer of the high-rise building. The system captures construction process image signals. When the controller inputs a signal to the positioning module, activating it, the module picks up the positioning signal of the construction site of the concrete top layer of the high-rise building. When the controller inputs a signal to the luminous strip, activating it, the strip releases a light signal at the construction site of the concrete top layer of the high-rise building. When the controller inputs a signal to the electric push rod III, activating it, the moving seat III moves within the receiving tank IV, causing the cylinder III to move up and down on the cylinder I. When the cylinder III is in a high position, the adjusting screw rotates in the threaded hole of the second crossbeam, tauting the pull wire and horizontally positioning the swing rod, thus activating the moving seat IV. When the cylinder III is in a low position, the pull wire causes the swing rod to tilt horizontally, moving the movable seat IV outward within the cylinder VII. This exerts a downward force on the cascading rod, compressing the spring II and causing it to move downward on the outer side of the upper wall of the cylinder III. This allows the ultrasonic transmitting and receiving contacts to slide out of the cylinder III. When the cylinder III is in a high position, the elastic energy stored in the spring II causes the swing rod to tilt horizontally, placing the movable seat IV at the inner end of the cylinder VII. This allows the ultrasonic transmitting and receiving contacts to retract into their original position within the cylinder III, adjusting the height of the ultrasonic transmitting and receiving contacts. This is useful when high-rise buildings require... During online monitoring of the construction of the concrete top layer of the building, the horizontal bars and support legs are placed at the designated installation positions according to the online monitoring system. The horizontal bars and support legs are connected to the reinforcing steel frame of the concrete top layer of the high-rise building via wires, through-holes in the horizontal bars and support legs, thus installing the support frame on the reinforcing steel frame. Before pouring the concrete, the outer end of the first horizontal beam is placed in receiving tank I, and the outer end of the second horizontal beam is placed in receiving tank II. The height of the outer end of the first horizontal beam in receiving tank I and the height of the outer end of the second horizontal beam in receiving tank II are adjusted according to the thickness of the concrete pour.The resistivity / dielectric constant sensor, vibration sensor, temperature and humidity sensor, and ultrasonic transmitter / receiver contact are positioned above the concrete pouring surface of the high-rise building. The intermediate connecting bolt located in receiving hole I is rotated, causing the inner end face of the intermediate connecting bolt in receiving hole I to act on the outer surface of the first and second crossbeams respectively, thereby mounting the first and second crossbeams on the bracket. When the high-rise building concrete is poured, the controller is activated, and the electric push rod I is used to bring the resistivity / dielectric constant sensor and vibration sensor to a low position, causing the resistivity / dielectric constant sensor... The vibration sensor is in contact with the poured concrete. The resistivity / dielectric constant sensor picks up the concrete slurry concentration distribution signal, and the vibration sensor picks up the vibration energy distribution signal. The pouring thickness of the high-rise building concrete is marked by the length scale lines on the left and right vertical rods. After the high-rise building concrete pouring is completed, the electric push rod I separates the resistivity / dielectric constant sensor and the vibration sensor from the poured concrete, placing them in a high position. When the high-rise building concrete is curing, the electric push rod... The electric push rod II lowers the cylinder II, bringing the lower end face of the pad block into contact with the cured concrete surface. A temperature and humidity sensor picks up the signal indicating the temperature and humidity distribution of the cured concrete. The electric push rod III lowers the cylinder III, causing the ultrasonic transmitter / receiver to slide out of the cylinder III and into contact with the cured concrete surface. The ultrasonic transmitter / receiver picks up the signal indicating the density distribution of the concrete. After curing the high-rise building concrete, the electric push rod II raises the cylinder II, separating the lower end face of the pad block from the cured concrete surface. The electric push rod III then lowers the cylinder II, bringing the lower end face of the pad block into contact with the cured concrete surface. Push rod section III elevates cylinder section III, allowing the ultrasonic transmitter and receiver contacts to retract into their original positions within cylinder section III and separate from the cured concrete surface. Signals related to concrete slurry concentration distribution, vibration energy distribution, concrete curing temperature and humidity distribution, concrete density distribution, construction process images of the high-rise building's concrete top layer, and the construction site location of the high-rise building's concrete top layer are transmitted to the controller. These signals are then transmitted wirelessly to a cloud-based data analysis and early warning platform. The cloud-based platform utilizes AI algorithms for fusion analysis, establishing a model relating resistivity to laitance thickness, displaying real-time changes in laitance layer thickness, generating vibration energy cloud maps, visually identifying vibration blind zones and over-vibration zones, calculating evaporation rates, and providing early warnings of crack risks. If any parameter exceeds a preset threshold, the system immediately triggers multi-level warnings. After completing online monitoring of the high-rise building's concrete top layer construction, the intermediate connecting bolt located in receiving hole I rotates in the opposite direction.Separate the inner end face of the intermediate connecting bolt located in receiving hole I from the outer surfaces of the first and second crossbeams. Remove the outer end of the first crossbeam from receiving groove I, and remove the outer end of the second crossbeam from receiving groove II. Cut off the portions of the left and right vertical members that extend above the concrete top layer of the high-rise building.

[0039] The present invention is designed, and its steps are as follows: 1. Monitoring process 1) Deployment Phase Before pouring the final layer of concrete, several monitoring devices are evenly distributed inside the formwork or placed directly on the concrete surface. The devices contact the concrete through the bottom of the casing, and the scale on the outer wall allows for visual verification of the embedment depth.

The gateway base station then uploads the data to a cloud platform via a 4G / 5G network.

[0041] 4) Intelligent Analysis and Early Warning Stage After receiving the data, the cloud platform uses AI algorithm models for fusion analysis: Establish a model showing the relationship between resistivity and slurry thickness, and display the changes in slurry layer thickness in real time; generate a "vibration energy cloud map" to intuitively display the vibration blind zone and over-vibration zone; calculate the evaporation rate and provide early warning of crack risk; once any parameter exceeds the preset threshold, the system immediately triggers multi-level early warning.

[0042] 5) Recycling and Reuse Stage After the concrete has initially set but before it has fully set, the device can be removed, cleaned, and reused at the next construction site.

The horizontal bar, left vertical bar, right vertical bar, support leg, receiving groove I, receiving groove II, receiving hole I, cylinder I, moving seat I, intermediate isolation plate, and electric... The design of the following technical features—push rod part I, cap part, mounting base part, spring part I, mounting plate part, clamping strip part, receiving groove part III, receiving groove part IV, receiving groove part V, receiving hole part II, receiving hole part III, receiving hole part IV, receiving groove part VI, cylinder part II, moving base part II, electric push rod part II, pad part, tightening screw part, receiving hole part V, cylinder part III, moving base part III, cascading rod part, spring part II, moving base part IV, ear part, swing rod part, pull wire part, adjusting screw part, electric push rod part III, and receiving groove part VII—complies with the technical features of the Patent Law and its implementing regulations.

[0050] The technical advantages of this invention are as follows: I. Real-time performance and process controllability Traditional large-volume concrete construction relies heavily on post-construction sampling or manual judgment, failing to achieve dynamic monitoring throughout the entire process. This invention, by integrating multi-parameter sensors and wireless transmission technology, enables real-time data acquisition and transmission throughout the entire concrete pouring, vibration, and curing process. It can detect problems such as excessively thick laitance, insufficient vibration, or abnormal temperature and humidity in the immediate aftermath, guiding on-site personnel to promptly perform secondary vibration, grouting, or adjust curing measures. This effectively avoids the accumulation of quality defects and the high costs of subsequent treatment. II. Improvement in Monitoring Accuracy and Scientific Rigor In existing technologies, the thickness of the slurry layer is mostly estimated manually based on experience, and the vibration effect depends on the operator's subjective judgment, lacking quantitative basis. This invention uses a resistivity / dielectric constant sensor to directly reflect the slurry concentration distribution. By establishing a resistivity-slurry thickness relationship model, it achieves precise quantitative monitoring of the slurry layer thickness. Simultaneously, a three-dimensional accelerometer objectively records the vibration energy and effective range, generating a vibration energy cloud map to scientifically identify under-vibration and over-vibration areas, significantly improving the scientific rigor and accuracy of quality assessment. III. Multi-parameter fusion and comprehensive evaluation capabilities Traditional monitoring methods are often singular and fragmented, making it difficult to comprehensively assess the quality of concrete construction. This invention, for the first time, integrates three key indicators—homogeneity (resistivity), density (vibration acceleration), and durability (temperature and humidity)—into a single system. Through multi-source data fusion and intelligent analysis, it achieves a comprehensive and systematic assessment of the quality of the top layer of concrete construction, overcoming the limitations of traditional methods that are one-sided and fragmented. IV. Intelligent Analysis and Decision Support Leveraging cloud-based artificial intelligence algorithms, this invention can automatically process massive amounts of monitoring data, enabling functions such as slurry thickness analysis, vibration energy assessment, and temperature and humidity early warning. The analysis results and warning information are displayed in real-time through a visual interface (Web / APP). This significantly reduces reliance on human experience, enhances the digitalization and intelligence of construction management, and provides reliable decision support for project quality control. V. Reusability and Wide Applicability: The device of this invention features a sealed shell design, allowing for recycling and reuse after the initial setting of concrete, thus reducing the cost of single-point monitoring. Furthermore, this device and method are not only applicable to structures such as bridge piers and cap beams, but can also be extended to various large-volume concrete projects such as dams, nuclear power plants, and high-rise building foundations, demonstrating broad engineering applicability and promising prospects for wider application. In summary, this invention fundamentally improves the control capability of construction quality of top-floor concrete structures by organically combining multi-parameter intelligent sensing, real-time transmission, and cloud-based intelligent analysis, demonstrating significant practicality, advanced technology, and economic efficiency.

[0051] In this technical solution, the construction of the concrete top layer of a high-rise building is carried out while the backup database is obtained through online parameter acquisition and monitoring. This online parameter acquisition and monitoring, which obtains the backup database, is achieved by resistivity / dielectric constant sensors, vibration sensors, temperature and humidity sensors, and ultrasonic transmitting and receiving contacts.

[0086] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0087] A method for online monitoring of the construction of the concrete top layer of a high-rise building, one of the first embodiments of the present invention, comprises the following steps: When the controller 50 inputs a signal to the electric actuator I24, causing the electric actuator I24 to be in working condition, it drives the U-shaped toothed body of the movable seat I22 to move in the receiving groove V203, and drives the mounting seat 26 and mounting plate 28 to move up and down in the cylindrical part I21, thereby adjusting the height position of the resistivity / dielectric constant sensor 10 and the vibration sensor 20. When the controller 50 inputs a signal to the electric actuator II 43, causing it to be in working condition, it drives the movable seat II 42 to move within the receiving tank III 201, and drives the cylindrical part II 41 to move up and down on the cylindrical part I 21, thereby adjusting the height position of the temperature and humidity sensor 30. When the controller 50 inputs a signal to the camera 70, causing the camera 70 to be in working condition, it captures image signals of the construction process of the concrete top layer of the high-rise building. When the controller 50 inputs a signal to the positioning module 80, causing the positioning module 80 to be in working condition, it picks up the positioning signal of the construction site of the concrete top layer of the high-rise building. When the controller 50 inputs a signal to the light-emitting strip 90, causing the light-emitting strip 90 to be in working condition, it releases a light signal at the construction site of the concrete top layer of the high-rise building. When the controller 50 inputs a signal to the electric push rod section III 610, causing it to be in working condition, it drives the movable seat section III 62 to move within the receiving tank IV 202, and drives the cylindrical section III 61 to move up and down on the cylindrical section I 21. When the cylindrical section III 61 is in a high position, the adjusting screw section 69 rotates in the threaded hole of the second crossbeam 5, causing the pull cable section 68 to be taut, the swing rod section 67 to be in a horizontal position, and the movable seat section IV 65 to be positioned at the inner end of the receiving tank VII 611. When the cylindrical section III 61 is in a low position, the pull cable section 68 causes the swing rod section 67 to be in a horizontal tilted position. The movable seat part IV 65 moves outward within the receiving tank VII 611, exerting a downward force on the cascading rod part 63. This compresses the spring part II 64, causing the cascading rod part 63 to move downward on the outer side of the upper top wall of the cylindrical part III 61. This allows the ultrasonic transmitting and receiving contact 40 to slide out of the cylindrical part III 61. When the cylindrical part III 61 is returned to its elevated position, the elastic energy stored in the spring part II 64 causes the swing rod part 67 to be in a horizontal position. This positions the movable seat part IV 65 at the inner end of the receiving tank VII 611, allowing the ultrasonic transmitting and receiving contact 40 to retract into its original position within the cylindrical part III 61. This adjusts the height of the ultrasonic transmitting and receiving contact 40. When online monitoring of the construction of the concrete top layer of a high-rise building is required, the horizontal bar 11 and the support leg 14 are placed at the designated installation positions according to the online monitoring system. The horizontal bar 11 and the support leg 14 are connected to the reinforcing steel frame of the concrete top layer of the high-rise building via wires, through-holes in the horizontal bar 11 and the support leg 14, thus installing the bracket 1 on the reinforcing steel frame of the concrete top layer. Before the concrete is poured, the outer end of the first horizontal beam 3 is placed in the receiving tank I 15, and the outer end of the second horizontal beam 5 is placed in the receiving tank II 16, according to the concrete top layer of the high-rise building. The thickness of the poured soil is adjusted to regulate the height of the outer end of the first crossbeam 3 in the receiving tank I 15 and the height of the outer end of the second crossbeam 5 in the receiving tank II 16. This allows the resistivity / dielectric constant sensor 10, vibration sensor 20, temperature and humidity sensor 30, and ultrasonic transmitter / receiver contact 40 to be positioned above the concrete pouring surface of the high-rise building. The intermediate connecting bolt located in the receiving hole I 17 is rotated, causing the inner end face of the intermediate connecting bolt in the receiving hole I 17 to act on the outer surface of the first crossbeam 3 and the outer surface of the second crossbeam 5, thereby mounting the first crossbeam 3 and the second crossbeam 5 on the support 1. When concrete is poured for a high-rise building, the controller 50 is activated. The electric push rod I24 lowers the resistivity / dielectric constant sensor 10 and the vibration sensor 20 to a low position, bringing them into contact with the poured concrete. The resistivity / dielectric constant sensor 10 captures the concrete slurry concentration distribution signal, and the vibration sensor 20 captures the vibration energy distribution signal. The pouring thickness of the concrete is marked using the length scale lines on the left vertical rod 12 and the right vertical rod 13. After the concrete pouring is complete, the electric push rod I24 raises the resistivity / dielectric constant sensor 10 and the vibration sensor 20 to a high position, separating them from the poured concrete. When the concrete of a high-rise building is being cured, the electric push rod II 43 lowers the cylinder II 41, bringing the lower end face of the pad 44 into contact with the cured concrete surface. The temperature and humidity sensor 30 picks up the signal indicating the temperature and humidity distribution of the cured concrete. The electric push rod III 610 lowers the cylinder III 61, causing the ultrasonic transmitter / receiver 40 to slide out of the cylinder III 61 and into contact with the cured concrete surface. The ultrasonic transmitter / receiver 40 picks up the signal indicating the density distribution of the concrete. After the curing of the high-rise building concrete is completed, the electric push rod II 43 raises the cylinder II 41, separating the lower end face of the pad 44 from the cured concrete surface. The electric push rod III 610 raises the cylinder III 61, causing the ultrasonic transmitter / receiver 40 to retract into its original position within the cylinder III 61 and separate from the cured concrete surface. Signals indicating the distribution of concrete slurry concentration, vibration energy, temperature and humidity during concrete curing, and concrete density, along with images of the construction process of the concrete top layer of the high-rise building and the location of the construction site, are transmitted to controller 50. From there, the signals are transmitted wirelessly to a cloud-based data analysis and early warning platform. On this platform, an AI algorithm model is used for fusion analysis to establish a model relating resistivity to slurry thickness. The platform displays real-time changes in slurry layer thickness, generates a vibration energy cloud map, visually identifies vibration blind spots and over-vibration zones, calculates evaporation rates, and provides early warnings of crack risks. If any parameter exceeds a preset threshold, the system immediately triggers multi-level warnings. After online monitoring of the construction of the concrete top layer of the high-rise building is completed, the intermediate connecting bolt located in the receiving hole I17 is rotated in the opposite direction, so that the inner end face of the intermediate connecting bolt located in the receiving hole I17 is separated from the outer side of the first crossbeam 3 and the outer side of the second crossbeam 5. The outer end of the first crossbeam 3 is taken out from the receiving groove I15, and the outer end of the second crossbeam 5 is taken out from the receiving groove II16. The part of the left vertical rod 12 and the part of the right vertical rod 13 that are higher than the concrete top layer of the high-rise building are cut off.

[0088] A method for online monitoring of the construction of the concrete top layer of a high-rise building, the second embodiment of the present invention, comprises the following steps: 1. Monitoring process 1) Deployment Phase Before pouring the final layer of concrete, several monitoring devices are evenly distributed inside the formwork or placed directly on the concrete surface.

[0089] 2) Monitoring phase (1) Pouring stage: Resistivity sensors monitor the changes in the water-cement ratio of concrete to reflect the distribution of slurry concentration; (2) Vibration stage: Three-dimensional accelerometers monitor vibration energy and identify under-vibration, over-vibration and vibration blind spots; (3) Curing stage: Temperature and humidity sensors monitor changes in concrete temperature and humidity to assess the effectiveness of curing conditions; (4) Throughout the process: The positioning module records the precise geographical location of each measuring point, enabling traceability of quality data; 3) Data transmission stage The MCU controls a low-power wireless module (BLE or LoRa) to transmit the collected multi-parameter data to a gateway base station deployed at the construction site in real time or at regular intervals. The gateway base station then uploads the data to a cloud platform via a 4G / 5G network.

[0090] 4) Intelligent Analysis and Early Warning Stage After receiving the data, the cloud platform uses AI algorithm models for fusion analysis: Establish a model showing the relationship between resistivity and slurry thickness, and display the changes in slurry layer thickness in real time; generate a "vibration energy cloud map" to intuitively display the vibration blind zone and over-vibration zone; calculate the evaporation rate and provide early warning of crack risk; once any parameter exceeds the preset threshold, the system immediately triggers multi-level early warning.

[0097] In verifying this invention, the inventors abandoned the existing technical characteristics of relying mainly on manual experience and single-parameter detection methods for top-level quality control in large-volume concrete construction. They first proposed a technical feature of constructing the concrete top layer of high-rise buildings while maintaining an online parameter acquisition and monitoring system with a backup database. This resulted in the first unexpected technical effect: enabling full-process monitoring of concrete pouring and curing of the top layer of high-rise buildings, thus improving the effectiveness of concrete pouring and curing. The second unexpected technical effect was achieved through the use of supports 1, intermediate tube frame 2, first crossbeam 3, first side tube frame 4, second crossbeam 5, and second side tube frame 6. The resistivity / dielectric constant sensor 10, vibration sensor 20, temperature and humidity sensor 30, and ultrasonic transmitter / receiver contact 40 monitor the construction process of the top layer of a high-rise building, achieving multi-point signal monitoring of the top layer and full-coverage online monitoring. This results in a third unexpected technical effect: data processing and transmission of monitoring signals via controller 50 and battery 60, enabling data exchange with a cloud-based data analysis and early warning platform. This also results in a fourth unexpected technical effect: the capture of construction process image signals via camera 70, establishing an image database. Finally, this achieves a fifth unexpected technical effect: [further details needed for a complete translation]. By using the positioning module 80 to locate the construction position, continuous recording of the construction process of the top layer of the high-rise building was achieved, resulting in the sixth unexpected technical effect: The use of the luminous strip 90 to emit light signals enabled the calibration of the construction position of the top layer of the high-rise building, resulting in the seventh unexpected technical effect: The use of the intermediate cylindrical frame 2 to buffer and support the resistivity / dielectric constant sensor 10 and clamp and support the vibration sensor 20 improved the performance of both sensors, resulting in the eighth unexpected technical effect: The use of the first side cylindrical frame 4 to internally install the temperature and humidity sensor 30 improved... The temperature and humidity sensor 30 improved its accuracy in picking up temperature and humidity, resulting in a ninth unexpected technical effect: it enabled the sliding installation of the ultrasonic transmitter and receiver contact 40 via the second side frame 6, improving the reliability of the contact between the ultrasonic transmitter and receiver contact 40 and the cured concrete surface. This resulted in a tenth unexpected technical effect: it eliminated the reliance on manual experience and single-parameter detection methods for top-level quality control in large-volume concrete construction, and instead provided a database of concrete slurry concentration distribution, vibration energy distribution, concrete curing temperature and humidity distribution, and concrete density distribution, offering data references for the construction of the top-level concrete structure of high-rise buildings.

[0098] In the second embodiment of the present invention, the tube beam frame, resistivity / dielectric constant sensor 10, vibration sensor 20, temperature and humidity sensor 30 and ultrasonic transmitting and receiving contact 40 are interconnected in a manner that the construction of the concrete top layer of the high-rise building is carried out in a state of online parameter picking and monitoring to obtain a backup database.

[0103] The second embodiment of the present invention is based on the first embodiment. In the second embodiment of the present invention, the steps are as follows: the resistivity / dielectric constant sensor 10, vibration sensor 20, temperature and humidity sensor 30, and ultrasonic transmitter and receiver contact 40 are installed on the concrete top layer during construction using a cylindrical beam frame; the resistivity / dielectric constant sensor 10 and vibration sensor 20 enable online monitoring of parameters during concrete pouring; and the temperature and humidity sensor 30 and ultrasonic transmitter and receiver contact 40 enable online monitoring of parameters during concrete pouring and curing. This allows the construction of the concrete top layer of the high-rise building to be carried out while the backup database is obtained through online parameter acquisition and monitoring.

[0104] The second embodiment of the present invention is based on the first embodiment. This invention has the following characteristics: 1. By designing a cylindrical beam frame, resistivity / dielectric constant sensor 10, vibration sensor 20, temperature and humidity sensor 30, and ultrasonic transmitter / receiver contact 40, the resistivity / dielectric constant sensor 10, vibration sensor 20, temperature and humidity sensor 30, and ultrasonic transmitter / receiver contact 40 are installed on the concrete top layer during construction.

Establish a model of the correspondence between resistivity and laitance thickness, display the change of laitance layer thickness in real time, generate vibration energy cloud map, intuitively display the vibration blind zone and over-vibration zone, calculate the evaporation rate, and warn of crack risk. Once any parameter exceeds the preset threshold, the system immediately triggers multi-level warnings. After completing the online monitoring of the construction of the concrete top layer of the high-rise building, rotate the intermediate connecting bolt in the receiving hole I (17) in the opposite direction, so that the inner end face of the intermediate connecting bolt in the receiving hole I (17) is separated from the outer side of the first crossbeam (3) and the outer side of the second crossbeam (5). Take out the outer end of the first crossbeam (3) from the receiving tank I (15), take out the outer end of the second crossbeam (5) from the receiving tank II (16), and cut off the part of the left vertical rod (12) and the part of the right vertical rod (13) that are higher than the concrete top layer of the high-rise building. Alternatively, the steps are:

1. Monitoring process 1) Deployment Phase Before pouring the final layer of concrete, several monitoring devices are evenly distributed inside the formwork or placed directly on the concrete surface.

The gateway base station then uploads the data to a cloud platform via a 4G / 5G network. 4) Intelligent Analysis and Early Warning Stage After receiving the data, the cloud platform uses AI algorithm models for fusion analysis: Establish a model showing the relationship between resistivity and slurry thickness, and display the changes in slurry layer thickness in real time; generate a "vibration energy cloud map" to visually display the vibration blind zone and over-vibration zone; The system calculates the evaporation rate and provides early warnings of crack risk; once any parameter exceeds a preset threshold, the system immediately triggers multi-level warnings. 5) Recycling and Reuse Stage After the concrete has initially set but before it has fully set, the device can be removed, cleaned, and reused at the next construction site.
