Description

Technical Field

[0001] The present invention relates to the technical field of intelligent assembly and monitoring and deviation correction of steel structure corridors, and in particular to an intelligent method and system for monitoring and correcting deformation of steel structure corridors. Background Art

[0002] In modern construction projects, steel structure corridors are structural elements that connect different building blocks and provide pedestrian passages. Due to their beauty and flexible design, steel structure corridors have been widely used in high-rise buildings, large commercial complexes and other buildings.

[0003] However, affected by factors such as the environment, load and construction technology, the steel structure corridor may deform and change its posture during the assembly process, which may affect the stability and safety of the building structure. This is because the traditional assembly construction process usually lacks an immediate monitoring and feedback mechanism, which makes it difficult for on-site technicians to obtain key data in a timely and accurate manner during the construction process. When minor quality problems accumulate to a certain extent, they often become irreparable. This makes quality control difficult to achieve, and potential problems in the production and construction process are difficult to discover and correct in time, which in turn affects the quality of the final product.

[0004] At present, the assembly construction of overweight large steel structure corridors uses steel lattice columns or steel columns as the tire frame of the steel corridor, uses instruments such as total stations for irregular observations, and manually calculates the deflection deformation of the main beam, which is inefficient and cannot be monitored in real time. As the steel corridor is continuously assembled, its deadweight increases, and the deflection changes continue to increase. Adding more tire frames to cope with the deflection deformation of the steel corridor adds more safety risks to the assembly construction of the steel corridor, which is inefficient and complex. It is difficult to flexibly control the deflection deformation of the steel corridor main beam. In addition, other existing professional monitoring systems (existing bridge monitoring systems, etc.) fail to provide solutions for the overall deflection monitoring of steel structures.

[0005] In order to timely monitor the deformation and posture of the corridor, the present invention develops an intelligent steel structure corridor deformation monitoring system and a monitoring method thereof to ensure the safe operation of the building. Summary of the invention

[0006] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide an intelligent method for monitoring and correcting the deformation of a steel structure corridor, so as to solve the problem that the prior art cannot timely monitor the deformation and posture of the corridor.

Determine whether the support column and the middle part of the corridor are deformed according to the deflection of the mid-span main beam; When the mid-span main beam deflection γ=0, it indicates that the corridor has not deformed and the monitoring ends; When the mid-span main beam deflection γ≠0, it is determined that the corridor has been deflected and the following steps are continued; S3, based on the displacement data between the deformation measuring points, obtaining the lifting displacement difference and the torsional deformation value; S4. Setting parameters of the deviation correction device based on the lifting displacement difference and the torsional deformation value, and correcting the corridor through the deviation correction device.

The calculation formula is as follows: N= N1- N2.

[0014] Preferably, the specific steps of S4 are as follows: S41, when γ≠0, adjust the displacement by repeatedly adjusting the hydraulic system according to the lifting displacement difference and the torsional deformation value, until the γ value meets the deflection control threshold of the steel structure, so that the main beam is restored to the deflection deformation range permitted by the specification; after the adjustment is completed, adjust the bearing block to a position flush with the upper bearing surface of the hydraulic system; S42. When the height adjustment H of the bearing block is close to the main beam, the hydraulic servo is fine-tuned through the control system so that the bearing block can fine-tune the displacement h along with the hydraulic servo so that H+h =γ, thereby offsetting the flexural deformation value of the main beam in the middle of the span.

In addition, the invention aims to promote technological innovation in the field of steel structure corridor assembly, improve production efficiency and quality control level, and reduce the risk of human operation, thereby achieving more significant technical and economic benefits in the field of building structures.

[0019] (4) Traditional monitoring of steel structure corridors mostly relies on manual or periodic inspections, which can easily lead to the failure to detect abnormal deformation of the structure in a timely manner. Intelligent monitoring methods achieve real-time monitoring through sensors and Internet of Things technology. They can collect deformation data of steel structures at any time, identify potential problems in a timely manner, and automatically issue warnings when the structural deformation exceeds the preset threshold, avoiding delayed response. Traditional deformation monitoring relies on manual operation, which is costly and inefficient. The intelligent monitoring system can automatically collect data, analyze deformation trends, and generate reports, greatly reducing manual participation and improving monitoring efficiency. At the same time, it can operate 24 hours a day, achieving long-term continuous monitoring and reducing maintenance costs. The intelligent monitoring system can continuously monitor the deformation of the corridor for a long time and accumulate a large amount of historical data. These data can provide a basis for subsequent structural health assessment and life prediction, and help make scientific maintenance and repair decisions in the future.

[0029] The deflection of the mid-span main beam includes the deflection of the upper mid-span main beam and the deflection of the lower mid-span main beam. The calculation steps are as follows: The calculation steps of the lower left relative displacement Δ1 and the lower right relative displacement Δ2 are as follows: S121. According to the displacement data A1 of the lower left deformation measuring point and the displacement data A2 of the lower mid-span deformation measuring point, the left relative displacement Δ1 is obtained. The calculation formula is as follows: Δ1=A2-A1; S122, according to the displacement data A3 of the lower right deformation measuring point and the displacement data Δ2 of the lower mid-span deformation measuring point, the lower right relative displacement Δ2 is calculated, and the calculation formula is as follows: Δ2=A2- A3.

[0030] S12, according to the lower left relative displacement Δ1 and the lower right relative displacement Δ2, the deflection of the main beam in the lower span γ is obtained 下 , the calculation formula is as follows: γ 下 = (Δ1+Δ2) / 2; The calculation steps of the upper left relative displacement Δ3 and the upper right relative displacement Δ4 are as follows: S131, according to the displacement data A4 of the upper left deformation measuring point and the displacement data A5 of the upper mid-span deformation measuring point, the upper left relative displacement Δ3 is obtained, and the calculation formula is as follows: Δ3=A5-A4; S132, according to the displacement data A6 of the upper right deformation measuring point and the displacement data A5 of the upper mid-span deformation measuring point, the right relative displacement Δ4 is ​​obtained, and the calculation formula is as follows: Δ4=A5-A6; S13, according to the upper left relative displacement Δ3 and the upper right relative displacement Δ4, the deflection of the upper mid-span main beam γ is obtained 上 , the calculation formula is as follows: γ 上 =(Δ3+Δ4) / 2.

[0031] S2. Determine whether the support column and the middle part of the corridor are deformed according to the deflection of the mid-span main beam; For the lower main beam, when γ 下 =0, the deformation measuring points A1, A2, and A3 are on the same straight line, indicating that the beam has not deformed; 下 When ≠0, the deformation measuring points A1, A2, and A3 are not on the same straight line, and it is judged that the beam has undergone flexural deformation.

[0032] For the upper main beam, when γ 上 =0, the deformation measuring points A4, A5, and A6 are on the same straight line, indicating that the beam has not deformed; 下 When ≠0, the deformation measuring points A4, A5, and A6 are not on the same straight line, and it is judged that the beam has undergone flexural deformation.

[0034] S4. Setting parameters of a deviation correction device based on the lifting displacement difference and the torsional deformation value, and correcting the corridor through the deviation correction device; S41. The left and right ends of the hydraulic servo instrument are connected to the bearing blocks, and the upper end is connected to the column bearing plate. By adjusting the height of the bearing block and fine-tuning the hydraulic servo instrument, the deformation of the corridor can be controlled.

[0035] When γ>0, the height of the bearing block is increased at the mid-span deformation measuring point according to the lifting displacement difference and the torsional deformation value, and then the bearing block is lifted and fine-tuned by the hydraulic servo instrument. The height of the bearing block is lifted along with the hydraulic servo instrument until the γ value meets the deflection control threshold of the steel structure, so that the main beam is restored to the deflection deformation range permitted by the specification; When γ<0, the height of the bearing block needs to be lowered in the middle of the span, and the hydraulic servo instrument is used to make fine adjustments according to the lifting displacement difference and torsional deformation value. The height of the bearing block is lowered along with the hydraulic servo instrument until the γ value meets the deflection control threshold of the steel structure, so that the main beam is restored to the allowable deflection deformation range of the specification.

[0036] The deflection control threshold of steel structures can be found in Appendix B Allowable Deformation of Structures or Components of the "Standard for Design of Steel Structures" (GB 50017-2017).

[0037] When the adjusted height H of the bearing block is close to the main beam, the hydraulic servo is fine-tuned through the control system so that the bearing block can fine-tune the displacement h along with the hydraulic servo so that H+h =γ, thereby offsetting the mid-span flexural deformation value of the main beam.

[0038] Embodiment 2 An intelligent steel structure corridor deformation monitoring system, comprising: The sensor network is used to set deformation measuring points on the bearing surface of the corridor support column, collect displacement data of each deformation measuring point, and obtain the deflection of the main beam in the mid-span based on the displacement of the surrounding deformation measuring points relative to the mid-span deformation measuring point; Intelligent control unit, Determine whether the support columns and the middle part of the corridor have deformed based on the deflection of the mid-span main beam; When the mid-span main beam deflection γ=0, it means that the beam has not deformed, and the steps are stopped; When the main beam deflection γ≠0, it is determined that the beam has been bent and deformed, and the steps are continued; the corridor correction device obtains the lifting displacement difference and the torsional deformation value based on the displacement data between the deformation measuring points, sets the parameters of the correction device based on the lifting displacement difference and the torsional deformation value, and corrects the corridor through the correction device. It is used to correct the corridor through the correction device based on the relative deformation data; the communication module is used to monitor the manufacturing process in real time through the cloud platform and remotely operate the system at any time.

[0039] The sensor network includes but is not limited to a static level 8, a wind speed sensor, and a stress sensor. The sensor has an automatic calibration function, which can accurately and stably collect environmental parameters and manufacturing process data, improve the reliability and accuracy of the system, monitor abnormal conditions during the assembly of the corridor, cover the entire steel structure corridor installation process, and ensure that all key data can be obtained in a timely and accurate manner.

[0040] The signal input end of the intelligent control unit is connected to the signal output end of the sensor network.

[0041] The command receiving end of the intelligent control unit is connected to the command output end of the communication module. Users can monitor the lifting and assembly process of the high steel structure anytime and anywhere through the cloud platform, and issue commands to the intelligent control unit. This remote operation method not only improves the flexibility of operation, but also reduces the need for human intervention and reduces production costs. The communication module also uses a secure encrypted communication protocol to ensure the security of remote monitoring and remote operation and prevent unauthorized access and interference.

[0042] The command receiving end of the corridor correction device is connected to the command output end of the intelligent control unit. The corridor correction device includes multiple independent hydraulic servos. The command receiving end of the hydraulic servo is connected to the command output end of the communication module through the intelligent control unit. The hydraulic servo is connected to the bottom of the column bearing plate, and the top of the column bearing plate carries the corridor body, so as to realize the lifting control and correction of the upper corridor. Users can monitor the corridor assembly process anytime and anywhere through the cloud platform, and perform remote operations as needed to improve the flexibility of operation and reduce production costs. When the sensor network detects relative deformation of the support column 1 and the middle part of the corridor body, intelligent correction adjustment is performed through the hydraulic servo and the height of the adjustment bearing block 2.

[0043] The communication module of the corridor lifting system supports real-time data transmission and cloud storage, allowing users to access historical data and generated reports of the manufacturing process anytime and anywhere, providing convenience for production management. The servo in the hydraulic correction device can control the lifting of the corridor and adjust the height of the bearing block at the same time, so as to realize the transfer of the bearing force to the bearing block. By adjusting the height of the bearing block multiple times, the load of the upper corridor can be dispersed and borne, avoiding the risk of failure of the hydraulic system.

[0044] The steel structure corridor is installed on the steel structure frame. In addition to monitoring the deformation of the corridor during the assembly process, after the assembly is completed, the deformation of the foundation can be stabilized and then corrected to ensure the accuracy of the final connection between the steel structure corridor and the left and right buildings, avoiding internal stress caused by uneven foundation and settlement. At the same time, the independent hydraulic lifting device of the present invention is conducive to the disassembly of the frame after the construction is completed.

[0045] Instructions for use: The sensor network collects wind direction data, wind speed data, and initial hoisting data, and outputs the collected data to the intelligent control unit through the signal output terminal; the intelligent control unit adjusts the control strategy according to the real-time data in the manufacturing process to cope with different environments and process changes, ensuring the stability and efficiency of the corridor manufacturing process and ensuring that appropriate working conditions are always maintained. When the parameters in the sensor are lower than the preset values, the intelligent control unit will issue an alarm to promptly handle and correct possible problems to ensure the quality and safety of corridor assembly. The manual or intelligent control unit will start the servo instruments of each supporting column through the communication module for fine-tuning. After fine-tuning, the status of the corridor will be judged again, and the hoisting will be completed if it is qualified; if it is unqualified, continue to perform intelligent analysis and correction.
