[0042] The present application will be described below in conjunction with the drawings in the present application.

[0043] As shown in the drawings, Figs. 1-2 A high-low variable rail sliding method for a large-span steel roof, according to the present application, specifically includes the following steps:

[0044] S1, obtaining site structure parameters, meteorological parameters, steel roof parameters and load parameters of the sliding construction operation at the construction site;

[0045] The site structure parameters include:

[0046] Geological conditions: with the help of geological exploration drilling technology, the stratum distribution, soil type and soil thickness of the construction site are investigated in detail; the soil physical and mechanical properties such as soil density, water content and shear strength are determined by using soil test; the ground bearing capacity is evaluated to determine whether the foundation needs to be reinforced to prevent track deformation and steel roof instability caused by foundation settlement during the sliding construction process; advanced technologies such as geological radar and ground imaging are used to scan whether there are obstacles such as old foundations and pipelines underground at the construction site; the position, shape and size of the obstacles are determined to avoid damage to underground facilities during construction and ensure smooth laying of the sliding track;

[0047] Existing building layout: using total station, laser scanner and other measuring equipment, the position and size of the existing buildings at the construction site and around are accurately measured, and detailed building layout drawings are drawn; the relative position relationship between the existing buildings and the steel roof construction area is accurately grasped to prevent collision during the sliding construction process; the structure design drawings of the existing buildings are collected to analyze their structure type, bearing capacity and other characteristics; the influence of the existing buildings during the steel roof sliding construction process is evaluated, and appropriate protective measures are taken if necessary;

[0048] Surrounding environment: on-site investigation of the road conditions around the construction site, including road width, traffic capacity, traffic flow, etc.; understanding the access routes of transport vehicles to ensure smooth transportation of construction materials and equipment, while avoiding serious impact on the surrounding traffic; evaluating the open space around the construction site to determine whether it can be used as a material storage, equipment parking or temporary processing site to optimize the utilization efficiency of the construction site;

[0049] The meteorological parameters include:

[0050] Real-time weather monitoring: Install anemometers and wind vanes at the construction site to monitor wind speed and direction in real time. Because strong winds can adversely affect the sliding process of the steel roof, changing its stress state and movement trajectory, accurate wind speed and direction information can help take appropriate wind protection measures during construction to ensure safety. Use temperature and humidity sensors to monitor temperature and humidity in real time. Changes in temperature and humidity can affect the physical properties of steel and welding quality.

[0051] Meteorological history data collection: Collect historical meteorological data for the area where the construction site is located, including wind speed, rainfall, temperature, and other information over the years. By analyzing historical weather data, we can predict adverse weather conditions during construction and develop contingency plans in advance to reduce the impact of weather factors on construction.

[0052] The steel roof parameters include:

[0053] Component size and shape: Analyze the design drawings of the steel roof to obtain information such as the size and shape of each component. For components with complex shapes, use three-dimensional modeling techniques for accurate simulation to ensure accurate installation and positioning during construction.

[0054] Material and connection method: Identify the material type, strength grade, and other parameters of the steel roof components, and understand the connection method between components.

[0055] Load parameters: Calculate the self-weight of the steel roof based on the design drawings and selected materials, including the weight of steel and connecting components. Consider the weight of equipment and facilities that may be permanently installed on the steel roof, such as lighting equipment and ventilation ducts, to accurately determine the size of the constant load. Analyze the live load that the steel roof may bear during construction. According to local weather conditions and building structure design specifications, reasonably estimate the size and distribution of live load.

[0056] In this step, the geological conditions of the construction site are comprehensively and detailedly surveyed through geological exploration, soil test, and geological radar, etc. advanced technologies, ensuring the accurate assessment of the foundation bearing capacity and providing reliable basic data for the design and construction of the sliding track. The existing building layout is accurately measured using total station, laser scanner and other measuring equipment, and a detailed building layout drawing is drawn, effectively avoiding the risk of collision with existing buildings during construction. The road conditions and open spaces around the construction site are investigated to optimize the utilization efficiency of the construction site and ensure the smooth transportation of construction materials and equipment. The wind speed, wind direction, temperature, humidity and other meteorological parameters of the construction site are monitored in real time to provide a basis for taking appropriate wind and temperature change prevention measures during construction and to ensure construction safety. By collecting and analyzing historical weather data, the possible severe weather during construction is predicted, and a response plan is developed in advance to reduce the impact of weather factors on construction. The design drawings of the steel roof are analyzed to obtain information such as the size, shape, material and connection method of each component of the steel roof, providing a guarantee for the accurate installation and positioning of the steel roof. The self-weight and possible dead load and live load of the steel roof are calculated to provide a basis for equipment selection and track design for sliding operation, improving the precision and efficiency of construction. This step provides a solid foundation for subsequent sliding operation scheme design by comprehensively and accurately obtaining various parameters of the construction site, improving the safety, precision and efficiency of construction.

[0057] S2, comprehensively analyze the site structure parameters, meteorological parameters, steel roof parameters and load parameters to obtain the sliding operation scheme design;

[0058] Analysis of site structure parameters:

[0059] According to the results of geological exploration and soil test, the bearing capacity and stability of the foundation are evaluated. For cases where the foundation bearing capacity is insufficient or there are soft soil layers, a foundation reinforcement scheme is designed to ensure the stability of the sliding track. Combined with the building layout drawing and structural design drawing, the relative position relationship between existing buildings and steel roof construction area is analyzed to determine the layout scheme of the sliding track to avoid collision with existing buildings. At the same time, the possible impact on existing buildings during sliding is evaluated, and appropriate protection measures are developed. According to the evaluation results of road conditions and open spaces, the entry and exit routes of transport vehicles and material storage sites are planned to ensure smooth logistics during construction. At the same time, considering the impact of the construction site on the surrounding traffic and environment, appropriate traffic diversion and environmental protection measures are developed;

[0060] Analysis of meteorological parameters:

[0061] According to the real-time monitoring data of anemometer, wind vane and temperature and humidity sensor, the influence of weather conditions on the sliding operation is analyzed. For strong wind, high temperature or low temperature and other adverse weather conditions, corresponding measures need to be taken, such as adjusting the sliding speed, strengthening the windproof facilities, etc. Combined with historical weather data, the possible severe weather conditions during construction are predicted, such as heavy rain, strong wind, etc. According to the prediction results, the response plan is made in advance to ensure the safety and progress of construction.

[0062] Analysis of steel roof parameters:

[0063] According to the design drawings and three-dimensional modeling results of the steel roof, the size, shape and connection mode of the components are analyzed, and the lifting and assembly scheme during the sliding process is determined. According to the material type and strength grade of the steel roof components, the appropriate sliding equipment and track material are selected. At the same time, considering the connection mode between components, the stability and connection reliability of components during the sliding process are ensured.

[0064] Analysis of load parameters:

[0065] According to the self-weight of the steel roof and the weight of the permanently installed equipment and facilities, the bearing capacity requirement of the sliding track and support structure is calculated. Ensure that the sliding track and support structure can bear the self-weight and dead load of the steel roof. Considering the live load borne by the steel roof during construction, the sliding operation scheme is adjusted according to the size and distribution of the live load to ensure the safety and stability during construction.

[0066] In this step, the bearing capacity and stability of the foundation are accurately evaluated through in-depth analysis of geological exploration and soil test results, and foundation reinforcement schemes are designed for cases where the foundation bearing capacity is insufficient or there are soft soil layers, effectively ensuring the stability of the sliding track and reducing the safety risks caused by foundation settlement; the relative position relationship between the existing buildings and the steel roof construction area is accurately analyzed in combination with the building layout drawing and structural design drawing, and the layout scheme of the sliding track is reasonably determined, effectively avoiding collision with existing buildings, and appropriate protection measures are formulated to further ensure safety during construction; according to the evaluation results of road conditions and open site, the entry and exit routes of transport vehicles and material storage sites are scientifically planned to ensure smooth logistics during construction and reduce construction delays caused by logistics problems; through analysis of the steel roof design drawing and three-dimensional modeling results, the size, shape and connection method of the components are determined, and a reasonable hoisting and assembly scheme is developed to improve the efficiency of the sliding operation; real-time monitoring and analysis of the weather conditions at the construction site, and appropriate measures are developed to deal with adverse weather conditions such as strong winds, high temperatures or low temperatures, enhancing the adaptability of the sliding operation to weather conditions; in combination with historical weather data, the possibility of severe weather during construction is predicted, and a response plan is developed in advance to ensure that construction safety and progress are not affected by severe weather; according to the weight of the steel roof and the weight of the permanently installed equipment and facilities, the bearing capacity requirements of the sliding track and support structure are accurately calculated to ensure that the sliding track and support structure can withstand the weight of the steel roof and dead load; considering the live load borne by the steel roof during construction, the sliding operation scheme is adjusted according to the size and distribution of the live load to ensure stability and reliability during construction; this step obtains a scientific and reasonable sliding operation scheme design by comprehensively analyzing site structural parameters, weather parameters, steel roof parameters and load parameters, effectively ensuring the safety, efficiency, adaptability and stability of the sliding operation.

[0067] S3、According to the sliding operation scheme design, carry out the high-low variable track sliding operation of the large-span steel roof, and real-time collect the sliding parameters of the steel roof; the sliding parameters include displacement parameters, velocity parameters, acceleration parameters, stress parameters and temperature parameters;

[0069] Comprehensively check the sliding equipment to ensure that it is in good working condition;

[0070] According to the sliding operation scheme design, install and debug all monitoring equipment, including displacement sensors, velocity sensors, accelerometers, stress strain gauges and thermometers;

[0071] Professional training is provided to personnel involved in the sliding operation to ensure their familiarity with the sliding operation process, operation specifications, and emergency handling measures. The responsibilities and division of labor of each personnel are clearly defined to ensure collaboration and coordination during the construction process.

[0072] According to the sliding operation scheme design, the sliding equipment is set up.

[0073] Safety warning signs and isolation belts are set up to ensure the safety of the construction site.

[0074] Adjust the steel roof to the starting position of the sliding operation and ensure its correct docking with the sliding track. Temporarily fix the steel roof to prevent accidental movement during the sliding process.

[0075] According to the sliding operation scheme design, start the sliding equipment and begin the sliding operation of the steel roof.

[0076] During the sliding process, closely monitor the movement state of the steel roof to ensure stable contact and advancement with the sliding track. When the steel roof needs to be changed to a higher or lower track, operate according to the track change strategy in the sliding operation scheme design. During the track change process, pay attention to the stress state of the steel roof and the changes in the movement trajectory to ensure smooth and safe track change.

[0077] The step of collecting the sliding parameters of the steel roof includes:

[0078] Use displacement sensors to monitor the displacement changes of the steel roof during the sliding process in real time and record the data. Ensure the accuracy and reliability of the displacement data for subsequent analysis and evaluation of the effect of the sliding operation.

[0079] Use speed sensors and accelerometers to monitor the speed and acceleration changes of the steel roof during the sliding process in real time. Analyze the speed and acceleration data to evaluate the smoothness and control effect of the sliding process.

[0080] Use stress strain gauges to monitor the stress state changes of the steel roof during the sliding process. Ensure that the stress data is within a safe range to prevent damage or failure of the steel roof due to excessive stress.

[0081] Use thermometers to monitor the environmental temperature and temperature changes of the steel roof in real time.

[0082] In this step, through the comprehensive inspection of the sliding device, it is ensured that it is in good working condition, effectively avoiding the interruption of construction or safety accidents caused by equipment failure; all monitoring devices are installed and debugged, including displacement sensors, speed sensors, accelerometers, stress strain gauges and thermometers, which provide reliable technical support for real-time collection and analysis of sliding parameters; personnel involved in sliding operation are trained professionally, responsibilities and division of labor are clarified, and the cooperation and coordination ability of the construction team is improved, ensuring the smooth progress of the sliding operation; according to the sliding operation scheme design, the sliding device is set up, and safety warning signs and isolation belts are set up, providing a good construction environment for the sliding operation; adjust the steel roof to the starting position of the sliding operation, and ensure that it is correctly connected with the sliding rail, effectively avoiding the difficulty of sliding or safety hazards caused by position deviation; during the sliding process, the motion state of the steel roof is closely observed to ensure that it maintains stable contact and advancement with the sliding rail; when high-low rail change is needed, operate according to the rail change strategy, pay attention to the stress state of the steel roof and the change of the motion trajectory, and ensure the smoothness and safety of the rail change process; real-time collection and analysis of sliding parameters provide basis for construction adjustment; use displacement sensors to monitor the displacement change of the steel roof in the sliding process in real time, and record data, which provides accurate and reliable data support for subsequent analysis and evaluation of the effect of sliding operation; through the speed sensor and accelerometer, the speed and acceleration change of the steel roof in the sliding process are monitored in real time, the data is analyzed to evaluate the smoothness and control effect of the sliding process, which helps to find and adjust the problems in the construction process in time; use stress strain gauges to monitor the stress state change of the steel roof in the sliding process, ensure that the stress data is within the safe range, and effectively prevent the steel roof from being damaged or failed due to excessive stress; through the thermometer, the environmental temperature of the construction site and the temperature change of the steel roof are monitored in real time, considering the influence of temperature on the sliding operation, providing basis for taking corresponding adjustment and control measures; S3 step ensures the safety and reliability of the sliding device, improves the accuracy and controllability of the sliding operation, and provides basis for construction adjustment by real-time collection and analysis of sliding parameters, effectively ensuring the safe and smooth progress of the high-low rail sliding operation of the large-span steel roof.

[0083] S4, compare the collected sliding parameters of the steel roof with the preset standard parameter threshold to obtain sliding parameter analysis results;

[0084] The influencing factors of the preset standard parameter threshold include:

[0085] Steel roof structure design parameters: The size, shape, material and connection method of steel roof components determine their own mechanical properties and deformation characteristics; different steel strength grades and component section forms will make the stress and deformation of the steel roof during sliding different, thereby affecting the threshold setting of displacement, stress and other parameters; the allowable displacement and stress change range of steel roof with large span and complex structure may be relatively small, and the threshold needs to be set more accurately;

[0086] Site conditions: The site structure parameters of the construction site, such as geological conditions and existing building layout, have an important influence on the preset standard parameter threshold; if the site geology is soft, it may produce larger settlement during the sliding process of the steel roof, so the threshold of the displacement parameter needs to be adjusted according to the settlement characteristics of the site; the layout of the surrounding existing buildings may also limit the sliding path and range of the steel roof, thereby affecting the setting of the threshold of related parameters;

[0087] Load conditions: The load acting on the steel roof includes dead load, live load and environmental load such as wind load; the dead load is composed of the weight of the steel roof itself, and the live load involves the weight of personnel and equipment during construction; environmental loads such as wind load have uncertainty and need to be evaluated according to local weather conditions and the environment in which the building is located; the size and distribution of the load directly affect the stress state of the steel roof, and then determine the threshold of stress, displacement and other parameters; for example, in areas with large wind load, wind-induced vibration may cause additional stress and displacement of the steel roof, so the threshold of stress and displacement parameters needs to be adjusted accordingly to ensure construction safety;

[0088] Construction technology and equipment: The performance of the sliding construction technology and equipment used will also affect the preset standard parameter threshold; different sliding construction technologies, such as traction sliding and push sliding, have different force modes and sizes on the steel roof, which will lead to differences in the mechanical response of the steel roof during the sliding process; the precision and stability of the construction equipment will also affect the setting of the parameter threshold; if the control precision of the equipment is high, it can more accurately control the sliding process of the steel roof, so the parameter threshold can be set more strictly; otherwise, the threshold needs to be appropriately relaxed;

[0089] Similar engineering experience: Referring to the experience of similar large-span steel roof sliding construction projects is also an important factor in setting the preset standard parameter threshold; by analyzing the problems, accidents and successful experiences of similar projects during construction, we can understand the variation law and reasonable range of different parameters in actual construction, thereby providing reference and lessons for the threshold setting of the current project, avoiding repeated mistakes, and optimizing the threshold setting;

[0090] The obtaining step of the sliding parameter analysis result comprises:

[0091] The real-time collected displacement data is compared with the preset standard parameter threshold value of displacement threshold value; it is checked whether the displacement is within the safety range and whether it is consistent with the design requirements; if the displacement is found to be abnormal, the cause should be analyzed immediately and measures should be taken;

[0092] The real-time collected speed and acceleration data are compared with the preset standard parameter threshold value; the change trend of speed and acceleration is analyzed, and the smoothness of the sliding process is evaluated; if the speed or acceleration is found to be abnormal, the control parameters of the sliding equipment should be adjusted in time;

[0093] The real-time collected stress data is compared with the preset standard parameter threshold value; it is checked whether the stress state of the steel roof is within the safety range, whether there is stress concentration or overload phenomenon; if the stress is found to be abnormal, the sliding operation should be stopped immediately, and the structure of the steel roof is checked and safety is evaluated;

[0094] The real-time collected temperature data is compared with the preset standard parameter threshold value; the influence of temperature change on the sliding operation is analyzed, if the temperature is found to be abnormal, corresponding measures should be taken to adjust the working condition of the sliding equipment or the construction environment;

[0095] According to the result of parameter comparison, the sliding parameter analysis result is obtained, and the comparison report is generated.

[0096] In this step, by comprehensively considering the steel roof structure design parameters, site conditions, load conditions, construction technology equipment and similar engineering experience and other factors, the preset standard parameter threshold is set scientifically and reasonably; the real-time collected sliding parameters are compared with the preset threshold, the abnormal changes of displacement, velocity, acceleration, stress and temperature parameters can be found in time, and it is ensured that all parameters in the construction process are within the safe range; once the parameter is abnormal, the cause can be analyzed and measures can be taken to effectively prevent safety accidents and ensure the safety of construction personnel and the structural safety of the steel roof; by comparing the real-time collected sliding parameters with the preset threshold, the stability and control effect of the sliding process can be accurately evaluated; for abnormal changes of displacement, velocity, acceleration and other parameters, the control parameters of the sliding equipment can be adjusted in time to ensure the accuracy and stability of the sliding process; through the monitoring and analysis of stress parameters, stress concentration or overload phenomena can be found in time to avoid damage or failure of the steel roof during the sliding process and improve the construction quality; by referring to the similar engineering experience to set the preset standard parameter threshold and combining with the parameter comparison results in the actual construction process, the construction scheme and process can be continuously optimized; for the problems and abnormalities found in the parameter comparison, the causes can be analyzed and improvement measures can be proposed to provide experience and reference for the construction of subsequent similar projects; by continuously optimizing the construction scheme and process, the construction efficiency can be improved, the construction cost can be reduced, and the economic benefit of the whole project can be improved; the sliding parameter analysis results are presented in the form of comparison report to provide intuitive decision support and basis for construction management personnel; construction management personnel can adjust the construction plan and measures in time according to the parameter comparison results and analysis suggestions in the comparison report to ensure the smooth progress of the construction; the comparison report can also be used as an important basis for engineering acceptance and quality control to provide strong guarantee for the smooth delivery of the project; S4 step compares the collected steel roof sliding parameters with the preset standard parameter threshold to obtain sliding parameter analysis results, which not only ensures the safety and accuracy of the construction, but also optimizes the construction scheme and process and provides decision support and basis.

[0097] S5、according to the sliding parameter analysis results, the sliding operation is adjusted in time;

[0098] The principles followed in the timely adjustment of the sliding operation include:

[0099] Safety principle: ensure the safety of the sliding operation process and avoid any accidents that may cause personnel injury or structural damage; according to the analysis results of stress parameters, pay special attention to the stress state of the steel roof to ensure its safe operation within the safe range;

[0100] Smoothness principle: pursue the smoothness of the sliding process to reduce the adverse phenomena such as lag, bump or sudden acceleration and deceleration; by adjusting the velocity parameter and acceleration parameter, the running state of the sliding equipment is optimized to ensure the smooth movement of the steel roof;

[0101] Accuracy Principle: Ensure that the sliding operation is carried out according to the design requirements and reaches the predetermined displacement target; adjust the sliding path and speed in time according to the analysis results of displacement parameters to ensure the accurate positioning of the steel roof;

[0102] If the displacement parameters deviate from the preset trajectory or do not meet the design requirements, the reasons should be analyzed immediately; it may be caused by insufficient control accuracy of the sliding equipment, uneven track or wind influence, etc.; according to the analysis results, adjust the control parameters of the sliding equipment, correct the track or take wind-avoiding measures, etc.;

[0103] If the speed or acceleration parameters appear abnormal fluctuations, the smoothness of the sliding process should be evaluated; it may be caused by sliding equipment failure, improper operation or external interference, etc.; according to the analysis results, adjust the equipment control mode in time, optimize the operation process or eliminate external interference, etc.;

[0104] If the stress parameters exceed the safety range, the sliding operation should be stopped immediately and the steel roof should be checked for structure; it may be caused by unreasonable design of steel roof, excessive construction load or uneven stress during sliding, etc.; according to the inspection results, the steel roof design needs to be adjusted, the construction load needs to be reduced or the sliding scheme needs to be optimized, etc.;
