Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a method and system for lifting and docking a multi-layer non-conversion truss steel corridor structure. Background Art

[0002] The connected buildings are widely used and favored by architects due to their advantages of transparency, lighting and fire protection. They have become landmark buildings due to their beautiful shapes. For connected buildings, aerial steel corridors are usually used to connect the tower structures to make them light and simple. In the construction process of connected structures, the focus used to be on the construction and installation of connected structures, mainly including high-altitude assembly, overall lifting and other processes, and the specific situation depends on the project situation. Among them, for the construction of steel corridors using the overall lifting process, it is necessary to focus on the safety and accuracy of the entire process of assembly, lifting and docking.

[0003] However, the stress of the steel corridor is greatly different from the design state when it is lifted. In the past, the lifting of the steel corridor between the connected buildings mainly selected the steel corridor conversion truss layer for lifting. After lifting to the right place, it was connected with the surrounding towers and then the upper steel corridor of the conversion layer was assembled at high altitude. This method has the advantages of light lifting weight and relatively small lifting control difficulties (the steel structure of the conversion truss layer has high rigidity and small deformation during the lifting process). For multi-layer steel corridor structures without conversion trusses, due to their low rigidity, the lifting process and deformation are large; after lifting to the right place, if the conventional operation is followed (directly connected to the surrounding towers and unloaded as a whole), the stress inside the steel corridor will inevitably be too different from the design state, which will cause major safety hazards in the use state. Summary of the invention

The objectives and other advantages of the present invention can be achieved and obtained through the following specification. Description of the Drawings

[0066] Figure 3 It is a schematic module diagram of a multi-layer non-conversion truss steel corridor structure lifting and docking system according to the present invention. Detailed implementation manners

[0067] As Figures 1-2 shown, the present invention provides a method for lifting and docking a multi-layer non-conversion truss steel corridor structure, including the following steps:

[0068] S1: Obtain the internal force control index, structural data of the non-conversion truss, image data and real-time monitoring data during the construction process;

[0069] S2: Calibrate the positions of the non-conversion truss lifted in place and the preset corbels according to the image data;

[0070] S3: Construct a finite element model based on the structural data of the non-conversion truss, and perform finite element simulation based on the finite element model and the internal force control index to obtain a hierarchical unloading and layered docking strategy;

[0071] S4: Perform layered docking on the non-conversion truss according to the hierarchical unloading and layered docking strategy, and adjust the hierarchical unloading and layered docking strategy according to the real-time monitoring data;

[0072] S5: Obtain the real-time monitoring data after docking is completed, determine the docking effect result and generate a construction report.

[0073] Working principle of the above technical solution: During the lifting and docking process of the multi-layer non-conversion truss, first, after lifting the multi-layer non-conversion truss to the required docking height, multi-angle images of the multi-layer non-conversion truss and the preset corbels are captured by cameras set at various positions on the tower to obtain image data; then, according to the image data, the relative positions of the preset corbels and the multi-layer non-conversion truss on the tower are adjusted to achieve the calibration of the docking point positions between the corbels and the non-conversion truss; after calibration, a finite element model is constructed based on the structural data of the non-conversion truss and the structural data of the preset corbels, etc. The structural data includes information such as the material strength, fatigue degree, and welding point positions of the non-conversion truss; then, finite element simulation is carried out based on the finite element model to simulate the construction strategy in which the internal force and deformation after the installation of the non-conversion truss both meet the internal force control indicators input by the construction personnel, and a hierarchical unloading and layered docking strategy is obtained; then, according to the docking hierarchy sequence and unloading ratio specified in the hierarchical unloading and layered docking strategy, the levels of the non-conversion truss are docked in sequence, and the sling ratio is unloaded; at the same time, during the unloading process, real-time monitoring data of the non-conversion truss is obtained, and the hierarchical unloading and layered docking strategy is adjusted according to the real-time monitoring data until the unloading is completed. The real-time monitoring data includes internal force and deformation data, etc. The internal force is obtained through pressure sensors set at the contact points, and the deformation data is obtained by calculating the moving pixel values from the images captured by cameras set on the tower walls and the non-conversion truss; finally, after the unloading is completed, the non-conversion truss after construction is detected and judged according to the real-time monitoring data after unloading to obtain the docking effect result; then, a construction report is generated based on the docking effect result, the real-time monitoring data during the construction process, and the real-time monitoring data after the construction is completed, thus completing the entire construction of the non-conversion truss.

[0074] Beneficial effects of the above technical solution: Through the above technical solution, by establishing a detailed docking process for the multi-layer non-conversion truss, the multi-layer hierarchical unloading and docking of the overall lifting of the multi-layer non-conversion truss are realized, and the docking and adjustment are carried out gradually from bottom to top, achieving controllable internal force and making the actual internal force consistent with the design state.

[0075] In one embodiment, the hierarchical unloading and layered docking strategy includes: docking hierarchy sequence, unloading ratio, and simulation data;

[0076] Carrying out layered docking of the non-conversion truss according to the hierarchical unloading and layered docking strategy, and adjusting the hierarchical unloading and layered docking strategy according to the real-time monitoring data, including:

[0077] S41: Docking and fixing the connection points of the corresponding levels of the non-conversion truss with the preset corbels according to the docking hierarchy sequence;

[0078] S42: After the fixing is completed, unload the slings according to the unloading ratio corresponding to the current docking hierarchy sequence;

[0079] S43: After the unloading is completed, obtain the real-time monitoring data of each monitoring point in the current docking level, and adjust the unloading ratio of the next level according to the real-time monitoring data and the simulation data to obtain the optimized unloading ratio;

[0080] S44: Fix the next docking level to the corresponding preset bracket after a preset time according to the docking level sequence, and perform sling unloading according to the optimized unloading ratio;

[0081] S45: Repeat the above steps S41 to S44 until all the transfer trusses are docked;

[0082] Working principle of the above technical solution: After the position calibration of the non-conversion truss and the preset corbel is completed, according to the docking level sequence, the connection point of the corresponding docking level at the first position in the docking level sequence is welded and fixed to the preset corbel. After the fixation is completed, according to the unloading ratio, the slings in the unloading ratio are unloaded as a whole, so as to complete the docking unloading of the current docking level; then the non-conversion truss is left static for half an hour (preset time); during the static process, construction workers can use devices such as cameras and ultrasonic detectors to conduct appearance detection on the non-conversion truss to detect whether cracks occur and conduct consultation and discussion; if there is no problem, after static, the real-time monitoring data of the current docking level is obtained, and then the real-time monitoring data is compared with the simulation data, and the unloading ratio of the next level is adjusted according to the comparison result to obtain the optimized unloading ratio; the simulation data is the internal force and deformation data of each monitoring point at different stages on each docking level during finite element simulation; specifically, after the unloading of one docking level is completed, the average value of the real-time monitoring data of each monitoring point is compared with the average value of the simulation data at the current stage. If the average value of the simulation data is greater than the average value of the real-time monitoring data, and the greater value exceeds the first preset ratio of the real-time monitoring data (preferably 3%), it means that the current load unloading is too little. When adjusting the unloading ratio of the next level, a certain ratio (generally increasing a ratio similar to the first preset ratio) of the unloading ratio will be increased to obtain the optimized unloading ratio; if the average value of the simulation data is less than the average value of the real-time monitoring data, and the greater value exceeds the second preset ratio of the real-time monitoring data (preferably 3%), it means that the current load unloading is too much. When adjusting the unloading ratio of the next level, a certain ratio (generally reducing a ratio similar to the second preset ratio) of the unloading ratio will be reduced to obtain the optimized unloading ratio; if the average value of the simulation data is equal to the average value of the real-time monitoring data, or the difference does not exceed the third preset ratio of the real-time monitoring data (preferably -3% to 3%), the unloading ratio of the next level will not be changed, and the unloading ratio of the next level will be directly used as the optimized unloading ratio; in order to ensure that the non-conversion truss is evenly stressed after the slings are unloaded, several slings are evenly distributed and connected to the non-conversion truss; therefore, during the adjustment of the unloading ratio, a corresponding sling is uniformly selected from each position to be unloaded together to determine the minimum value of the unloading ratio. At the same time, according to the principle of the unloading slings from bottom to top, the order of the unloading slings is determined; so that when increasing or decreasing the unloading ratio, only the minimum unloading ratio is considered for increase or decrease, so as to determine the specific value of the optimized unloading ratio after increase or decrease; after determining the optimized unloading ratio, the next docking level is docked and unloaded according to the docking level sequence and the optimized unloading ratio; then the above operations are repeated to determine the unloading ratio of the next new level until the docking unloading of all docking levels is completed, so that the docking unloading of the non-conversion truss is completed;Among them, during the unloading process of the last docking level, regardless of how the unloading ratio is adjusted, all slings will be unloaded;

[0083] Beneficial effects of the above technical solution: Through the above technical solution, by successively docking the docking levels and unloading a certain proportion of the unloading ratio, and continuously monitoring the internal force, the internal force control during the overall lifting of the multi-layer non-converted truss is realized, ensuring that the internal force after construction is consistent with the internal force at the time of design; at the same time, by adjusting the unloading ratio in stages, the possibility of damage to the multi-layer non-converted truss caused by load imbalance during the unloading process is avoided.

[0084] In one embodiment, position calibration of the lifted non-converted truss and the preset corbel according to the image data includes:

[0085] S21: Obtain the first image data of the non-converted truss, and adjust the non-converted truss to horizontal according to the first image data;

[0086] S22: Obtain the second image data between the current docking level and the preset corbel after adjusting to horizontal, and construct a docking three-dimensional model based on the second image data;

[0087] S23: Determine the coordinates of multiple docking positions of the current docking level in the docking three-dimensional model to obtain multiple first-type coordinates;

[0088] S24: Determine the coordinates of the preset corbel to be docked in the docking three-dimensional model to obtain multiple second-type coordinates;

[0089] S25: Adjust the position of the preset corbel according to the first-type coordinates and the second-type coordinates, and obtain the adjusted second-type coordinates after the adjustment is completed;

[0090] S26: Determine the correspondence between the first-type coordinates and the adjusted second-type coordinates, and calculate the relative position distance;

[0091] S27: Adjust the position of the non-converted truss according to the relative position distance to complete the position calibration of the non-converted truss and the preset corbel.

[0092] Working principle of the above technical solution: After lifting the non-conversion truss to the specified height, it is necessary to make the docking points at each level of the non-conversion truss correspond to the positions of the preset corbels as much as possible, so as to avoid the internal force imbalance caused by the deformation of the non-conversion truss beyond the plan in order to ensure welding; therefore, after the non-conversion truss is in place, the non-conversion truss is photographed from multiple angles by a camera to obtain the first image data, and then the plane to be leveled in the non-conversion truss is adjusted to be horizontal according to the first image data to complete the horizontal adjustment of the non-conversion truss; during the docking process, since the load of the sling is continuously unloaded, when corresponding the connection points at each level of the non-conversion truss to the positions of the preset corbels, it is necessary to re-align each level, and only adjust the position of the preset corbel; specifically, the position between the current docking level and the preset corbel is photographed from multiple angles by the set camera to obtain the second image data, and a docking three-dimensional model is established according to the second image data. The coordinates of the connection points in the current docking level are used as the first type of coordinates, and the connection points of the preset corbel are used as the second type of coordinates. Then, the position of the preset corbel is adjusted according to the first type of coordinates and the second type of coordinates, so that the positions of the first type of coordinates and the second type of coordinates correspond one by one, and then the relative distance is calculated according to the specific coordinate values, and then the horizontal position of the non-conversion truss is adjusted to complete the fixation; among them, during the process of adjusting the position of the preset corbel, since the preset corbel is generally connected to the tower through a hydraulic jack, the position adjustment of the preset corbel can be completed by adjusting the hydraulic jack; among them, when adjusting the horizontal position of the non-conversion truss, only the adjustment is carried out in the first order of the docking level sequence to avoid the deformation of the non-conversion truss; among them, the image data includes the first image data and the second image data; among them, the connection points of the non-conversion truss and the connection points of the preset corbel are identified by the connection point recognition model. The training process of the connection point recognition model is to use the three-dimensional model data to be recognized and the result data of the recognized connection points as sample data, and input the sample data into the initial neural network model for training until convergence to obtain the recognition model; it is processed by three-dimensional graphics processing software, a leveling three-dimensional model is generated according to the first image data, and a docking three-dimensional model is generated according to the second image data;

[0093] Beneficial effects of the above technical solution: Through the above technical solution, by strictly controlling the relative position of the non-conversion truss and the preset corbel before docking, the external deformation caused by construction is avoided, thereby improving the accuracy of internal force control.

[0094] In one embodiment, obtaining the first image data of the non-conversion truss and adjusting the non-conversion truss to be horizontal according to the first image data includes:

[0095] S211: Obtain the first image data of the non-conversion truss after lifting in place, construct a leveling three-dimensional model based on the first image data, and identify the plane to be leveled;

[0096] S212: Calculate the levelness of the plane to be leveled. The formula for calculating the levelness is as follows:

[0097]

[0098] where is the levelness, is the number of feature points selected on the plane to be leveled, is the vertical coordinate of the feature points on the plane to be leveled, is the average value of the vertical coordinates of the feature points on the plane to be leveled;

[0099] S213: Determine the target optimization function and constraint conditions based on the levelness. Among them, the target optimization function is as follows:

[0100]

[0101] The constraint conditions are as follows:

[0102]

[0103] where is the sling elongation corresponding to the sling connection point on the non-conversion truss corresponding to, is the matrix of all sling elongations, is the preset levelness;

[0104] S214: Solve the target function and constraint conditions based on the gradient descent method to obtain the sling elongation scheduling result;

[0105] S215: Control the sling length according to the sling elongation scheduling result, and adjust the non-conversion truss to be horizontal;

[0106] The working principle of the above technical solution: After the sling lifts the non-conversion truss in place, the multi-layer non-conversion truss is photographed from multiple angles by a camera to obtain the first image data; then a leveling three-dimensional model at the current position is generated based on the first image data, and then the plane to be leveled in the leveling three-dimensional model is identified; specifically, the plane to be leveled in the leveling three-dimensional model is identified through a pre-trained recognition model; then the levelness of the plane to be leveled is calculated. If the levelness of the plane to be leveled does not meet the preset levelness (i.e., constraint conditions), based on the determined optimization objective function and constraint adjustment, iterative solution is performed through the gradient descent algorithm to obtain the elongation scheduling result of the sling; then, according to the elongation scheduling result, the hydraulic system is controlled to adjust the length of the sling, thereby completing the horizontal adjustment of the non-conversion truss to the horizontal plane to be adjusted; among them, the training process of the recognition model is to use the three-dimensional model data to be recognized and the recognition result data as sample data, and input the sample data into the initial neural network model for training until convergence to obtain the recognition model;

[0107] Beneficial effects of the above technical solution: Through the above technical solution, by automatically leveling the non-conversion truss before docking with the preset corbel, the docking effect between the non-conversion truss and the preset corbel is improved; at the same time, the system automatically levels, avoiding manual adjustment by construction workers and improving the safety of construction.

[0108] In one embodiment, the position of the preset corbel is adjusted according to the first type of coordinates and the second type of coordinates, and after the adjustment is completed, the adjusted second type of coordinates is obtained, including:

[0109] S251: Select one of the second type of coordinates as the base point coordinates, and adjust the base point coordinates and the base point coordinate pair to the same horizontal line; wherein, the base point coordinate pair is the first type of coordinates corresponding to the base point coordinates;

[0110] S252: Determine the adjustment data according to the relative angle and position between the base point coordinate pair and the first type of coordinates;

[0111] S253: Adjust the relative position between the base point coordinates and the second type of coordinates according to the adjustment data, and after the adjustment is completed, the adjusted second type of coordinates is obtained;

[0112] Working principle of the above technical solution: After the horizontal adjustment is completed, the construction worker selects the second type of coordinates of a connection point corresponding to a preset corbel as the base point coordinates, and then determines the base point pair coordinates in the first type of coordinates according to the base point coordinates. The position of the preset corbel is adjusted through the two coordinates to make the two coordinates on the same horizontal line, and then the relative angle and position between the base point pair coordinates and other first type of coordinates are determined through three-dimensional coordinate operations. The relative angle and position relationship between the base point pair coordinates and other first type of coordinates is used as the adjustment data to adjust the positions of the base point coordinates and other second type of coordinates, thereby completing the one-to-one correspondence between the first type of coordinates and the second type of coordinates, that is, completing the position correspondence between the connection points of the current level and the connection points of the preset corbel;

[0113] Beneficial effects of the above technical solution: Through the above technical solution, by adjusting the levels of the connection points of each docking level and the connection points of the preset corbels, the deformation of the non-conversion truss caused by the unloading of the sling load and the problem of misalignment caused by the change of the connection position of the docking level are avoided; the accuracy of the docking between the non-conversion truss and the preset corbel is improved.

[0114] In one embodiment, real-time monitoring data after docking is obtained to determine the docking effect result and a construction report is generated, including:

[0115] S51: Obtain the internal force data, deformation data, and position data of the monitoring points on several non-conversion trusses after construction is completed, and process the internal force data and deformation data based on statistical principles to obtain standard internal force data and standard deformation data;

[0116] S52: Obtain the real-time monitoring data of the positions corresponding to the position data on the non-conversion truss after construction is completed; wherein, the real-time monitoring data includes: internal force data and deformation data;

[0117] S53: Determine the deviation values of the real-time monitoring data of each monitoring point from the standard internal force data and standard deformation data to obtain a deviation data set. The calculation formula for the deviation value is as follows:

[0118]

[0119] Wherein, is the deviation value of the th monitoring point, is the deformation data of the th monitoring point, is the standard deformation data of the th monitoring point, is the internal force data of the th monitoring point, is the standard internal force data of the th monitoring point;

[0120] S54: Calculate the docking coefficient according to the deviation data set. The calculation formula for the docking coefficient is as follows:

[0121]

[0122] Wherein, is the docking coefficient, is the number of monitoring points, is the weight corresponding to the deviation value, is the position data, is the weight corresponding to the position data;

[0123] S55: Determine the docking effect result according to the docking coefficient, and generate a construction report based on the real-time monitoring data after construction is completed and the docking effect result;

[0124] Among them, the docking effect result includes: qualified docking effect and unqualified docking effect;

[0125] Determining the docking effect result according to the docking coefficient includes:

[0126] Judge whether the docking coefficient is greater than the preset docking value; if the docking coefficient is greater than the preset docking value, judge that the docking effect of the non-conversion truss is unqualified; if the docking coefficient is not greater than the preset docking value, judge that the docking effect of the non-conversion truss is qualified.

[0127] The working principle of the above technical solution: After the docking and unloading of the non-conversion truss is completed, count the data of each key point of several multi-layer non-conversion trusses that have passed the acceptance in the past, and sort out these data. Based on the position information of the key points, determine the deformation data and internal force data of the key points, and then calculate the average values of the deformation data and internal force data of the same key points of several non-conversion trusses. Take the obtained average deformation data and average internal force data as the standard deformation data and standard internal force data; then extract the real-time monitoring data after the docking and unloading is completed according to the position information, collect the internal force data and deformation data of the monitoring points corresponding to the position information, and then calculate and determine the deviation values of the real-time monitoring data of each monitoring point from the standard internal force data and standard deformation data to obtain a deviation data set; then calculate the docking coefficient of the non-conversion truss according to the deviation data set, determine the docking effect result according to the docking coefficient, and generate a construction report based on the real-time monitoring data after construction is completed and the docking effect result; among them, when generating the docking effect result, judge whether the docking coefficient is greater than the preset docking value; if the docking coefficient is greater than the preset docking value, judge that the docking effect of the non-conversion truss is unqualified; if the docking coefficient is not greater than the preset docking value, judge that the docking effect of the non-conversion truss is qualified; among them, in the process of processing the internal force data and deformation data based on statistical principles to obtain the standard internal force data and standard deformation data, in order to ensure the accuracy of the calculation, each step uses software tools for calculation.
