Abstract
Description
Technical Field
[0001] This invention relates to the field of steel structure construction technology, and in particular to a monitoring device and construction method for the overall posture of a steel structure. Background Technology
[0002] Steel structure integral installation construction refers to the construction method of moving steel structure units (such as large-span roofs, truss structures, space frame structures, or bridge segments) that have been assembled on the ground or at a low position to the design elevation and position in one go or in stages through systematic construction techniques such as integral lifting, integral lowering, or jacking and sliding. This type of construction is usually characterized by large tonnage, large span, high-altitude operation, and multi-point synchronous control. It is technically complex and has a high risk level. It has extremely high requirements for the accuracy and real-time monitoring of structural spatial posture parameters (including plane position, elevation, height difference, tilt angle, and torsional deformation). It is the core technical link to ensure the structural stress safety and synchronous coordinated control of construction.
[0003] Currently, total stations are commonly used to measure the structural attitude and elevation differences during construction. This method requires pre-positioning measuring targets or reflectors at key nodes or control points of the steel structure being measured, ensuring stable and continuous line-of-sight between the instrument and the measuring points. However, during overall lifting or sliding, components, temporary support systems, hydraulic lifting equipment, construction platforms, or surrounding structures can easily obstruct the view, causing some measuring points to lose line-of-sight and creating monitoring blind spots. In this situation, complete attitude data of the structure at a specific stage cannot be obtained, potentially masking structural offsets, tilts, asynchronous displacements, or localized abnormal stresses, thus increasing the risk of structural instability or excessive stress on components. Furthermore, limitations in the number and location of measuring points make continuous, full-coverage monitoring of the entire structure difficult. The measurement process relies on manual operation and recording, which can easily lead to cumulative errors during site switching, instrument retesting, and data processing. Data acquisition is intermittent and delayed, making it difficult to meet the accuracy requirements of high-frequency, dynamic, and synchronous monitoring for the overall installation of large-span steel structures. Therefore, when structural posture deviates, it is often impossible to identify and adjust it in real time, which affects the level of precision control in the construction process and has potential adverse effects on construction safety and installation quality. Summary of the Invention
[0004] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this invention is to provide a monitoring device and construction method for the overall posture of steel structures. During the overall construction of the steel structure, it can continuously, dynamically, and automatically monitor and dynamically correct the spatial posture and displacement changes of the installed steel structure. It eliminates the need for additional measuring point targets or reflectors on the structural surface and does not rely on continuous manual measurement using conventional total stations; verification measurements are only required at a few key construction nodes. It effectively achieves continuous acquisition and analysis of structural planar displacement, elevation changes, tilt angles, and posture deviations, significantly improving monitoring efficiency and data continuity during the overall installation process. It reduces reliance on on-site measurement by surveyors, minimizes measurement errors caused by human operation, site changes, or obstructed views, and significantly improves construction accuracy, installation quality, and work efficiency, making it suitable for more complex construction needs.
[0005] To achieve this objective, the present invention adopts the following technical solution: A device for monitoring the overall attitude of a steel structure, comprising: Multiple attitude control mechanisms are respectively arranged at corresponding positions along the moving path of the steel structure. Each attitude control mechanism includes a support structure, a drive component, an attitude monitoring component, and a load-bearing component. The support structure is installed at a pre-installation position of the steel structure or on the opposite side of the pre-installation position. The drive component is disposed on the support structure and is used to drive the overall movement of the steel structure. The load-bearing component connects the drive component to the steel structure. The attitude monitoring component is disposed on the drive component and is arranged opposite to the steel structure. The attitude monitoring component includes a laser rangefinder and a communication unit. The laser rangefinder can emit a measuring laser to the surface of the steel structure and acquire displacement data. The communication unit is used to transmit the displacement data. The control platform is electrically connected to the communication unit and the drive component of each of the attitude control mechanisms, and is used to receive displacement data from the communication unit, calculate the attitude information of the steel structure, and control the drive component to move according to the attitude information.
[0006] In some alternative embodiments, multiple attitude control mechanisms are connected in series.
[0007] In some alternative embodiments, the attitude monitoring component further includes a housing, in which the laser rangefinder and the communication unit are both disposed, and a through hole is provided in the housing opposite to the light source emission position of the laser rangefinder.
[0008] In some optional embodiments, the communication unit includes a data interface, a power supply module, a data conversion module, and a communication module. The data interface is electrically connected to the laser ranging sensor and is used to receive the displacement data. The power supply module is electrically connected to the laser ranging sensor and is used to supply power to it. The data conversion module is electrically connected to the communication module and is used to convert the displacement data into a signal format recognizable by the control platform. The communication module is electrically connected to the control platform and is used to transmit the displacement data.
[0009] In some alternative embodiments, the power supply module includes an external power supply and a PoE splitter. The external power supply is connected to the communication module to superimpose a power signal onto the network signal. One end of the PoE splitter is connected to the communication module, and the other end is electrically connected to the laser rangefinder, for separating the power signal from the network signal and supplying power to the laser rangefinder; or... The power supply module includes a charging power supply disposed within the housing, the output of which is electrically connected to the laser ranging sensor.
[0010] In some optional embodiments, the control platform includes a data receiving module, a data processing module, a display module, and a control module. The data receiving module is communicatively connected to the communication unit and is used to receive displacement data of each moving point. The data processing module is used to calculate the height difference between each moving point and the overall attitude information based on the received data. The display module is used to display the attitude information in real time. The control module is electrically connected to the drive components of each attitude control mechanism and is used to control the action of the drive components based on the calculation results.
[0011] In some alternative embodiments, the control platform further includes a data storage module for storing the displacement data and calculation results.
[0012] A construction method for monitoring the overall attitude of a steel structure, employing the aforementioned monitoring device for the overall attitude of a steel structure, includes the following steps: S1: Assemble and initially position the steel structure to be installed at the construction site, and check its connection status and overall dimensions. S2: Multiple attitude control mechanisms are installed at positions corresponding to the movement path of the steel structure. Multiple support structures are arranged at the pre-installation position of the steel structure or on its opposite side. Each support structure is equipped with a drive assembly. The multiple drive assemblies are used to collaboratively drive the overall movement of the steel structure. Load-bearing members are installed, connecting the drive assemblies to the steel structure. Multiple attitude monitoring components are fixedly installed on the drive assemblies and arranged opposite to the steel structure. The laser ranging sensor in the attitude monitoring assembly emits a measuring laser to the surface of the steel structure to obtain displacement data. The communication unit is electrically connected to both the laser ranging sensor and the control platform. S3: Start the drive component to move the steel structure as a whole to the pre-installation position. At the same time, the attitude monitoring component continuously collects the displacement data of each moving point and sends it to the control platform through the communication unit. S4: The control platform receives the displacement data, calculates the displacement difference between each moving point, and obtains the overall posture information of the steel structure. When the displacement difference between any moving point and other moving points is greater than a preset threshold, the control platform generates an adjustment control command to control the corresponding drive component to perform compensation adjustment on the moving point until the displacement difference is restored to the preset threshold range.
[0013] In some optional embodiments, when the steel structure moves in a vertical direction, in step S2, the support structure is set at the pre-installation position of the steel structure; the load-bearing component is a steel strand, the driving component is a lifting component, the steel strand is arranged in a vertical direction, one end of which is connected to the lifting component and the other end is connected to the steel structure, and the lifting component lifts the entire steel structure to the pre-installation position by pulling the steel strand.
[0014] In some optional embodiments, when the steel structure slides in a horizontal or inclined direction, in step S2, the supporting structure is installed on the side opposite to the pre-installation position of the steel structure, the load-bearing member is a sliding beam, the sliding beam is arranged along the sliding path of the steel structure, the steel structure is slidably connected above the sliding beam, the driving component is a jacking member, the output end of which is slidably disposed on the sliding beam and abuts against the steel structure, and the jacking member pushes the steel structure to move along the sliding path on the sliding beam to the pre-installation position by jacking the steel structure.
[0015] The beneficial effects of this invention are: This invention provides a monitoring device and construction method for the overall attitude of a steel structure. Attitude control mechanisms are installed at corresponding positions of multiple moving points on the steel structure, working in conjunction with a control platform. When the drive component moves the steel structure, the attitude monitoring component collects displacement data from each moving point in real time and transmits it synchronously to the control platform via a communication unit. The control platform automatically calculates the planar displacement, elevation change, and tilt angle attitude information of each moving point, eliminating the need for continuous manual measurement and recording. This significantly reduces reliance on on-site measurement personnel and enables continuous acquisition and analysis of the overall spatial attitude of the steel structure, improving data integrity and continuity. When the displacement difference of any moving point exceeds a preset threshold, the control platform automatically controls the corresponding drive component to make compensation adjustments, forming a closed-loop adjustment mechanism of monitoring-analysis-control, achieving dynamic correction and precise control of the steel structure's attitude. The attitude monitoring component is fixedly installed on the drive component and directly aligned with the steel structure surface. It actively emits a measurement beam towards the steel structure surface and receives reflected signals, obtaining high-precision distance data without the need for additional reflectors or targets on the structural surface. Fixing the laser rangefinder sensor to the drive assembly ensures the stability of the relative position between the sensor and the steel structure during the measurement process, avoids high-altitude deployment and repeated disassembly and assembly, improves construction convenience and reduces safety risks.
[0016] Through real-time, continuous data analysis and dynamic correction, the device can effectively control planar offset, elevation error, and tilting issues of steel structures during movement, reducing cumulative errors caused by manual operation or measurement interruptions, and significantly improving construction accuracy, installation quality, and overall construction efficiency. The device can be set up in any direction (vertical, horizontal, or tilted) to adapt to different movement paths. Regardless of the direction of structural movement, it can continuously acquire displacement data, not relying on movement in a single direction, thus making it suitable for more complex construction needs and improving the versatility and feasibility of the technical solution.

[0026] Please refer to Figures 1 to 5As shown, this embodiment provides a monitoring device for the overall attitude of a steel structure, including multiple attitude control mechanisms and a control platform. The multiple attitude control mechanisms are respectively positioned at corresponding locations along the movement path of the steel structure 100. Each attitude control mechanism includes a support structure 1, a drive component 2, an attitude monitoring component 3, and a load-bearing member 4. The support structure 1 is installed at a pre-installation position of the steel structure 100 or on the opposite side of the pre-installation position. The drive component 2 is mounted on the support structure 1 and is used to drive the overall movement of the steel structure 100. The load-bearing member 4 connects the drive component 2 to the steel structure 100. The attitude monitoring component 3 is mounted on the drive component 2 and is positioned opposite to the steel structure 100. The attitude monitoring component 3 includes a laser rangefinder 31 and a communication unit 32. The laser rangefinder 31 can emit a measuring laser to the surface of the steel structure 100 and acquire displacement data. The communication unit 32 is used to transmit the displacement data. The control platform is electrically connected to the communication unit 32 of each attitude control mechanism and the drive component 2, and is used to receive the displacement data from the communication unit 32, calculate the attitude information of the steel structure 100, and control the drive component 2 to move according to the attitude information.
[0027] Attitude control mechanisms are installed at corresponding positions of more than 100 moving points on the steel structure. Each attitude control mechanism includes a support mechanism, an attitude monitoring component 3, and a drive component 2, and works in conjunction with the control platform. When the drive component 2 moves the steel structure 100, the attitude monitoring component 3 collects the displacement data of each moving point in real time and transmits it synchronously to the control platform through the communication unit 32. The control platform automatically calculates the planar displacement, elevation change, and tilt angle attitude information of each moving point, eliminating the need for continuous manual measurement and recording, significantly reducing reliance on on-site measurement personnel, and enabling continuous acquisition and analysis of the overall spatial attitude of the steel structure 100, improving the integrity and continuity of the data. When the displacement difference of any moving point exceeds a preset threshold, the control platform can automatically control the corresponding drive component 2 to make compensation adjustments, forming a closed-loop adjustment mechanism of monitoring-analysis-control, realizing dynamic correction and precise control of the attitude of the steel structure 100.
[0028] The attitude monitoring component 3 is fixedly mounted on the drive component 2 and directly aligned with the surface of the steel structure 100. Since the laser rangefinder 31 can actively emit a measurement beam and receive reflected signals, the surface of the steel structure 100 itself provides sufficient reflection intensity. Therefore, high-precision distance data can be obtained without additional reflectors or targets on the structure surface. Fixing the laser rangefinder 31 to the drive component 2 also ensures the stability of the relative position between the sensor and the steel structure 100 during measurement, avoiding high-altitude deployment and repeated disassembly and reassembly, improving construction convenience and reducing safety risks.
[0029] Through real-time and continuous data analysis and dynamic correction, this device can effectively control the planar offset, elevation error and tilt of the steel structure 100 during the movement process, reduce the cumulative error caused by manual operation or measurement interruption, and significantly improve construction accuracy, installation quality and overall construction efficiency.
[0030] Furthermore, the monitoring device for the overall posture of the steel structure can be set in any direction (vertical, horizontal, or inclined) to adapt to different movement paths. The drive component 2 can be a lifting component 21 or a jacking component 22, and applies driving force along the actual movement direction of the steel structure 100. The load-bearing component 4 can be a steel strand 41, a sliding beam 42, a support rod, etc., selected according to the movement direction and force characteristics to achieve lifting, jacking, or combined force action. The laser rangefinder 31 is installed on the drive component 2 and arranged opposite to the steel structure 100. It can be aligned with the moving point on the surface of the steel structure 100 and continuously acquire displacement data regardless of the movement direction of the structure. It does not rely on movement in a single direction, thus making it suitable for more complex construction needs and improving versatility and feasibility.
[0031] like Figure 1 As shown, for example, if the steel structure 100 is a square component, attitude control mechanisms are respectively set at the four corners of the steel structure 100 to monitor and control the displacement and attitude of each corner point in real time.
[0032] Among them, the support structure 1 can be a support plate, which is used to provide a stable mounting position for the drive component 2 and the attitude monitoring component 3.
[0033] Optionally, multiple attitude control mechanisms can be connected in series. This series connection facilitates unified scheduling and coordinated actions among the attitude control mechanisms, ensuring consistent movement throughout the overall installation process and preventing premature or delayed local movement points, thus reducing the risk of tilting, twisting, or shifting of the steel structure. Furthermore, it reduces the number of cables connecting each attitude control mechanism to the control platform; for large-span construction sites, it reduces wiring complexity and installation difficulty, while also minimizing potential interference and failure points.
[0034] like Figure 5As shown, in some embodiments, the attitude monitoring component 3 further includes a housing 33, in which the laser rangefinder 31 and the communication unit 32 are both disposed. A through-hole is formed in the housing 33 opposite to the light source emission position of the laser rangefinder 31. The housing 33 protects the laser rangefinder 31 and the communication unit 32 from dust, rain, splashing liquids, or construction debris, improving the reliability and service life of the attitude monitoring component 3 in complex construction environments. The through-hole in the housing 33 at the light source emission position of the laser rangefinder 31 allows the laser beam to be directed unobstructed onto the surface of the steel structure 100. This prevents the housing 33 from obstructing or causing light refraction, thus ensuring that the laser rangefinder 31 acquires high-precision displacement data.
[0035] In this embodiment, the communication unit 32 includes a data interface, a power supply module 321, a data conversion module 322, and a communication module. The data interface is electrically connected to the laser rangefinder 31 and is used to receive displacement data. The power supply module 321 is electrically connected to the laser rangefinder 31 and is used to supply power to it. The data conversion module 322 is electrically connected to the communication module and is used to convert the displacement data into a signal format recognizable by the control platform. The communication module is electrically connected to the control platform and is used to transmit the displacement data. Each module in the communication unit 32 has a clearly defined function and structure. The data interface ensures the completeness and real-time nature of the acquired displacement data. The data conversion module 322 ensures data compatibility, eliminating the need for complex processing of the original signal by the control platform. The communication module provides a stable and high-speed data transmission channel, ensuring the continuity and accuracy of the displacement data. Optionally, the data conversion module 322 can be implemented using a network cable conversion module, and the communication module can transmit data using both a network cable and a communication cable.
[0036] Furthermore, the power supply module 321 includes an external power supply 3212 and a PoE splitter 3211. The external power supply 3212 is connected to the communication module to superimpose a power signal onto the network signal. One end of the PoE splitter 3211 is connected to the communication module, and the other end is electrically connected to the laser rangefinder 31. It is used to separate the power signal from the network signal and supply power to the laser rangefinder 31. The external power supply 3212 is superimposed onto the network signal through the communication module and then separated by the PoE splitter 3211 to supply power to the laser rangefinder 31, eliminating the need for a separate power cable. This reduces the complexity of on-site wiring, especially in high-altitude, large-span steel structure construction environments, improving construction convenience and safety. Simultaneously, the PoE splitter 3211 can stably extract the power signal from the network signal, ensuring continuous power supply to the laser rangefinder 31. This avoids measurement interruptions or data anomalies caused by fluctuations in the external power supply 3212 or line losses, improving the reliability of the device.
[0037] In other embodiments, the power supply module 321 includes a charging power supply disposed within the housing 33, the output of which is electrically connected to the laser rangefinder 31; the built-in charging power supply reduces the need for external wiring, eliminates the need for dedicated power lines, and facilitates rapid deployment and relocation; it also does not rely on external power supply 3212 or network power supply, and can work independently, which is particularly suitable for high-altitude, large-span steel structure 100 construction scenarios, reducing construction complexity and safety risks.
[0038] In this embodiment, the control platform includes a data receiving module, a data processing module, a display module, and a control module. The data receiving module is communicatively connected to the communication unit 32 and is used to receive displacement data from each moving point. The data processing module is used to calculate the height difference between each moving point and the overall attitude information based on the received data. The display module is used to display the attitude information in real time. The control module is electrically connected to the drive components 2 of each attitude control mechanism and is used to control the action of the drive components 2 based on the calculation results. By modularly designing the control platform, each module has a clear function and cooperates with each other, forming a closed-loop monitoring-calculation-display-control system.
[0039] Specifically, the data receiving module can use an Ethernet port to connect to the communication unit 32 of the attitude control mechanism, receiving displacement data of each moving point in real time; buffering and processing signals to ensure data continuity and integrity. The data processing module can use an embedded processor (such as ARM or FPGA) to parse and calculate the received raw displacement data, generating the height difference, planar displacement, tilt angle, and overall attitude information of each moving point; it can perform threshold judgment and anomaly detection. The display module can use an LCD screen or a liquid crystal display screen to display the attitude of the steel structure 100, the status of each moving point, and deviation information in real time; providing a human-machine interface for construction personnel to monitor and operate. The control module can use relays or drive control boards to control the drive components 2 of each attitude control mechanism according to the calculation results output by the data processing module; realizing closed-loop dynamic correction and attitude adjustment.
[0040] Furthermore, the control platform also includes a data storage module for storing the displacement data and calculation results. A hard disk can be selected to store the original displacement data, calculation results, and monitoring history records, which facilitates subsequent analysis, verification, or traceability of construction quality.
[0041] This embodiment also provides a construction method for monitoring the overall attitude of a steel structure, using the monitoring device for the overall attitude of a steel structure from any of the above embodiments, and includes the following steps: S1: Assemble and initially position the steel structure 100 to be installed at the construction site, and check its connection status and overall dimensions. S2: Multiple attitude control mechanisms are installed at positions corresponding to the movement path of the steel structure 100. Multiple support structures 1 are arranged at the pre-installation position of the steel structure 100 or on its opposite side. Each support structure 1 is equipped with a drive assembly 2. The multiple drive assemblies 2 are used to collaboratively drive the overall movement of the steel structure 100. Load-bearing members 4 are installed, connecting the drive assemblies 2 to the steel structure 100. Multiple attitude monitoring components 3 are respectively fixedly installed on the multiple drive assemblies 2 and arranged opposite to the steel structure 100. The laser range sensor 31 in the attitude monitoring component 3 is used to emit a measuring laser onto the surface of the steel structure 100 to obtain displacement data. The communication unit 32 is electrically connected to the laser range sensor 31 and the control platform. S3: Start drive component 2 to move the steel structure 100 as a whole to the pre-installation position. At the same time, attitude monitoring component 3 continuously collects displacement data of each moving point and sends it to the control platform through communication unit 32. S4: The control platform receives displacement data, calculates the displacement difference between each moving point, and obtains the overall attitude information of the steel structure 100. When the displacement difference between any moving point and other moving points exceeds a preset threshold, the control platform generates an adjustment control command to control the corresponding drive component 2 to perform compensation adjustment on the moving point until the displacement difference is restored to the preset threshold range.
[0042] This method equips each moving point of the steel structure 100 with an attitude monitoring component 3 to collect displacement data in real time. After the data is transmitted to the control platform, the attitude information (plane displacement, elevation, tilt angle, etc.) of the entire steel structure 100 can be continuously calculated, avoiding the delays and errors caused by manual measurement and breakpoint measurement in traditional total stations. When the displacement deviation of any moving point exceeds a preset threshold, the control platform automatically generates adjustment commands and controls the corresponding drive component 2 to achieve a closed loop of monitoring-analysis-control. The steel structure 100 can compensate for errors in real time during movement, ensuring synchronization of each moving point, reducing construction deviations, and improving installation accuracy. The laser rangefinder 31 directly measures the surface of the steel structure 100, eliminating the need for reflectors or targets, simplifying construction preparation. Automatic data transmission and calculation reduce reliance on on-site surveyors and minimize measurement errors caused by operational errors or obstructed vision. Support structure 1 is positioned at the pre-installation location or on its opposite side. Drive assembly 2 and load-bearing components 4 are flexibly configured, supporting vertical lifting, horizontal sliding, tilting, or combined directional movement. This method is highly versatile and adaptable to various steel structure installation scenarios, meeting complex construction needs. Automated data acquisition and closed-loop control reduce the frequency of high-altitude operations and repetitive manual measurements. Construction personnel can observe posture information in real-time on the control platform, quickly identify and correct deviations, improving construction efficiency and reducing construction risks.
[0043] like Figure 1 and Figure 2 As shown, when the steel structure 100 moves vertically, in step S2, the support structure 1 is positioned at the pre-installation location of the steel structure 100; the load-bearing component 4 uses steel strand 41, and the drive assembly 2 uses a lifting component 21. The steel strand 41 is arranged vertically, with one end connected to the lifting component 21 and the other end connected to the steel structure 100. The lifting component 21 lifts the steel structure 100 to the pre-installation location by pulling the steel strand 41. Through the combination of the steel strand 41 and the lifting component 21, the lifting force is directly applied vertically to the center of gravity or key lifting points of the steel structure 100, reducing tilting, offset, or uneven force. The two provide a reliable force path, reducing the need for high-altitude operations, achieving precise, stable, and controllable lifting of the steel structure 100, while simplifying the construction layout, improving safety and automation levels, and is suitable for lifting the steel structure 100 vertically.
[0044] Among them, the lifting component 21 can be a hydraulic through-hole jack.
[0045] like Figure 3 and Figure 4 As shown, when the steel structure 100 slides horizontally or inclined, in step S2, the support structure 1 is installed on the opposite side of the pre-installation position of the steel structure 100. The load-bearing component 4 is a sliding beam 42, which is arranged along the sliding path of the steel structure 100. The steel structure 100 is slidably connected above the sliding beam 42. The driving component 2 is a jacking component 22, whose output end is slidably set on the sliding beam 42 and abuts against the steel structure 100. The jacking component 22 pushes the steel structure 100 along the sliding path on the sliding beam 42 to the pre-installation position. The sliding beam 42 bears the weight and pushing force of the steel structure 100, forming a stable load-bearing support surface, ensuring that the pushing force is transmitted along a predetermined path, so that the steel structure 100 is subjected to uniform force during the sliding process. Since horizontal or inclined movement requires maintaining a balance of contact and friction along a specific direction, the jacking component 22 directly abuts against the steel structure 100 and slides along the sliding beam 42 to output thrust. This allows for precise control of the steel structure 100's movement along a predetermined path, avoiding trajectory deviation or unstable sliding, and improving construction safety and controllability.
[0046] Among them, the jacking component 22 can be a hydraulic cylinder.
