Description

Technical Field

[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.

DETAILED DESCRIPTION

[0016] like Figure 1~2 As shown, the present invention provides a method for lifting and docking a multi-layer non-conversion truss steel corridor structure, comprising the following steps: S1: Obtain internal force control indicators, structural data of non-converted trusses, image data, and real-time monitoring data during construction; S2: Calibrate the position of the non-converted truss and the preset corbel lifted into place according to the image data; S3: Construct a finite element model based on the structural data of the non-transformed truss, and perform finite element simulation based on the finite element model and internal force control indicators to obtain the hierarchical unloading and layered docking strategy; S4: perform layered docking of the non-converted trusses according to the layered unloading and layered docking strategy, and adjust the layered unloading and layered docking strategy according to the real-time monitoring data; S5: Obtain the real-time monitoring data after the docking is completed to determine the docking effect results and generate a construction report.

[0017] The working principle of the above technical solution is as follows: in the process of lifting and docking multi-layer non-conversion trusses, first, after the multi-layer non-conversion trusses are lifted to the required docking height, multi-angle images of the multi-layer non-conversion trusses and preset corbels are taken by cameras arranged at various positions on the tower to obtain image data; then, the relative positions of the preset corbels on the tower and the multi-layer non-conversion trusses are adjusted according to the image data to achieve the calibration of the docking point position of the corbels and the non-conversion trusses; after the calibration, a finite element model is constructed according to the structural data of the non-conversion trusses and the structural data of the preset corbels, etc.; wherein the structural data includes information such as material strength, fatigue and welding point position of the non-conversion trusses; then, a finite element simulation is performed based on the finite element model to simulate a construction strategy in which the internal force and deformation of the non-conversion trusses after installation are in accordance with the internal force control indicators input by the construction personnel, and a graded unloading and layered docking strategy is obtained; then, the graded unloading and layered docking strategy is implemented according to the graded unloading and layered docking strategy. The docking level sequence and unloading ratio specified in the docking strategy are used to dock the levels of the non-converted trusses in turn, and unload them in accordance with the sling ratio; at the same time, during the unloading process, the real-time monitoring data of the non-converted trusses is obtained, and the hierarchical unloading and layered docking strategies are adjusted according to the real-time monitoring data until the unloading is completed; wherein, the real-time monitoring data include: internal force and deformation data, etc., the internal force is obtained by pressure sensors arranged at the contact points, etc., and the deformation data is obtained by taking images with cameras arranged on the tower wall and the non-converted trusses and then calculating the moving pixel values; finally, after the unloading is completed, the non-converted trusses after construction are inspected and judged according to the real-time monitoring data after the unloading is completed, and the docking effect results are obtained; then a construction report is generated according to the docking effect results, the real-time monitoring data during the construction process, and the real-time monitoring data after the construction is completed, thereby completing the entire construction of the non-converted trusses.

[0018] The beneficial effects of the above technical solution: Through the above technical solution, by establishing a detailed docking process for multi-layer non-conversion trusses, the multi-layer graded unloading and docking of the multi-layer non-conversion trusses can be achieved as a whole, and the docking and adjustment are gradually carried out from bottom to top to achieve controllable internal forces, so that the actual internal forces are consistent with the design state.

[0019] In one embodiment, the hierarchical unloading and layered docking strategy includes: docking level order, unloading ratio and simulation data; The non-converted trusses are docked in layers according to the hierarchical unloading and layered docking strategy, and the hierarchical unloading and layered docking strategy is adjusted according to the real-time monitoring data, including: S41: docking and fixing the connection points of the level corresponding to the non-converted truss with the preset corbels according to the docking level sequence; S42: when the fixing is completed, the sling is unloaded according to the unloading ratio corresponding to the current docking level sequence; S43: When the unloading is completed, the real-time monitoring data of each monitoring point in the current docking level is obtained, and the unloading ratio of the next level is adjusted according to the real-time monitoring data and the simulation data to obtain the optimized unloading ratio; S44: fixing the next docking level with the corresponding preset corbel after a preset time according to the docking level sequence, and performing sling unloading according to the optimized unloading ratio; S45: repeating the above steps S41 to S44 until the non-conversion truss docking is completed; The working principle of the above technical solution is as follows: after the position calibration between the non-converted truss and the preset corbel is completed, the connection point of the corresponding docking level that is at the first place in the docking level sequence will be welded and fixed to the preset corbel according to the docking level sequence. After the fixing is completed, the slings in the unloading ratio will be unloaded as a whole according to the unloading ratio, thereby completing the docking unloading of the current docking level; then the non-converted truss is left to stand for half an hour (preset time); during the standing process, the construction personnel can use equipment such as cameras and ultrasonic detectors to conduct appearance detection of the non-converted truss to detect whether cracks occur, and conduct consultations and discussions; if there is no problem, after standing, obtain the real-time monitoring data of the current docking level, and then compare the real-time monitoring data with the simulation data. , and adjust the unloading ratio of the next level according to the comparison result to obtain the optimized unloading ratio; wherein, the simulation data is the internal force and deformation data of each monitoring point at different stages on each docking level during the finite element simulation; specifically, after completing the unloading of a docking level, the average value of the real-time monitoring data of each monitoring point is compared with the average value of the simulation data of 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 (preferably 3%) of the real-time monitoring data, it means that the current load is unloaded too little. When adjusting the unloading ratio of the next level, the unloading ratio will be increased by a certain ratio (generally a ratio close to the first preset ratio), thereby obtaining 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 is greater than the second preset ratio (preferably 3%) of the real-time monitoring data, it means that the current load is unloaded too much, and when adjusting the unloading ratio of the next level, the unloading ratio will be reduced by a certain ratio (generally a ratio close to the second preset ratio) 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 (preferably -3% to 3%) of the real-time monitoring data, 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 tension on the non-conversion truss is uniform after the sling is unloaded, if The dry slings are evenly distributed and connected to the non-converted trusses; therefore, in the process of adjusting the unloading ratio, a corresponding sling is evenly selected from each position to be unloaded together, so as to determine the minimum value of the unloading ratio. At the same time, according to the principle of unloading the slings from bottom to top, the order of unloading the slings is determined; when increasing or decreasing the unloading ratio, only the minimum unloading ratio is considered to be increased or decreased, 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 repeat the above operation to determine the new unloading ratio of the next level, until the docking and unloading of all docking levels are completed, so that the docking and unloading of the non-converted trusses are completed;Among them, during the unloading process of the last docking level, all the slings will be unloaded regardless of how the unloading ratio is adjusted; The beneficial effects of the above technical scheme: Through the above technical scheme, by sequentially docking the docking levels and unloading a certain proportion of the unloading ratio, and constantly monitoring the internal force, the internal force in the process of overall lifting and docking of multi-layer non-conversion trusses can be controlled, ensuring that the internal force after construction is consistent with the internal force during design; at the same time, by adjusting the unloading ratio in stages, the possibility of damage to the multi-layer non-conversion trusses caused by load imbalance during the unloading process is avoided.

[0020] In one embodiment, the position of the non-transformed truss and the preset bracket lifted into place is calibrated according to the image data, including: S21: Acquire first image data of the non-converted truss, and adjust the non-converted truss to be horizontal according to the first image data; S22: Acquire second image data between the current docking level and the preset corbel after being adjusted to the horizontal level, and construct a docking three-dimensional model based on the second image data; S23: determining coordinates of a plurality of docking positions of a current docking level in the docking three-dimensional model, and obtaining a plurality of first-category coordinates; S24: determining the coordinates of the preset corbel to be docked in the docking three-dimensional model, and obtaining a plurality of second-category coordinates; S25: adjusting the position of the preset corbel according to the first type coordinates and the second type coordinates, and obtaining the adjusted second type coordinates after the adjustment is completed; S26: determining the corresponding relationship between the first type of coordinates and the adjusted second type of coordinates, and calculating the relative position distance; S27: The position of the non-converted truss is adjusted according to the relative position distance, and the position calibration of the non-converted truss and the preset corbel is completed.

[0021] The working principle of the above technical solution is as follows: after the non-converted truss is lifted to the specified height, it is necessary to make the docking points of each level of the non-converted truss correspond to the position of the preset corbel as much as possible, so as to avoid the internal force imbalance caused by the deformation of the non-converted truss outside the plan due to welding; so after the non-converted truss is in place, the non-converted truss is photographed at multiple angles by a camera to obtain first image data, and then the surface of the horizontal plane in the non-converted truss is adjusted to keep it horizontal according to the first image data, so as to complete the horizontal adjustment of the non-converted truss; and in the docking process, since the load of the sling is continuously unloaded, when the connection points of each layer of the non-converted truss correspond to the position of the preset corbel, each layer needs to be re-aligned, and only the position of the preset corbel is adjusted; specifically, the position between the current docking level and the preset corbel is photographed at multiple angles by a set camera to obtain 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 corbels are used as the second type of coordinates, and then the preset corbels are aligned according to the first type of coordinates and the second type of coordinates. The position is adjusted so that the positions of the first type of coordinates and the second type of coordinates correspond to each other, and then the relative distance is calculated according to the specific coordinate values, and then the horizontal position of the non-converted truss is adjusted to complete the fixation; wherein, in 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; wherein, when adjusting the horizontal position of the non-converted truss, only the first order of the docking hierarchy sequence is adjusted to avoid deformation of the non-converted truss; wherein, the image data includes the first image data and the second image data; wherein, the connection point of the non-converted truss and the connection point of the preset corbel are identified by the connection point recognition model, and the connection point recognition model training process is to use the three-dimensional model data to be identified and the result data of the identified connection point as sample data, input the sample data into the initial neural network model for training until convergence, and obtain the recognition model; and process it through the three-dimensional graphics processing software, generate a leveling three-dimensional model according to the first image data, and generate a docking three-dimensional model according to the second image data; Beneficial effects of the above technical solution: Through the above technical solution, by strictly controlling the relative position of the non-converted truss and the preset corbel before docking, additional deformation caused by construction is avoided, thereby improving the accuracy of internal force control.

[0022] In one embodiment, acquiring first image data of a non-transformed truss, and adjusting the non-transformed truss to a horizontal position according to the first image data, comprises: S211: Acquire first image data of the non-converted truss after being lifted into place, construct a leveling three-dimensional model based on the first image data, and identify the plane to be leveled; S212: Calculate the levelness of the plane to be leveled. The calculation formula of the levelness is as follows: in, is the horizontality, is the number of feature points on the selected horizontal plane, is the vertical coordinate of the feature point on the horizontal plane, is the average value of the vertical coordinates of the feature points on the horizontal plane; S213: Determine the target optimization function and constraint conditions based on the horizontality, wherein the target optimization function is as follows: The constraints are as follows: in, For sling connection points on non-transformed trusses The corresponding sling extension length, is the matrix of all sling elongations, To preset the level; S214: Solving the objective function and constraint conditions based on the gradient descent method to obtain the sling elongation scheduling result; S215: controlling the length of the sling according to the sling elongation scheduling result, and adjusting the non-conversion truss to be horizontal; The working principle of the above technical solution is as follows: after the sling lifts the non-transformation truss into place, the multi-layer non-transformation truss is photographed at multiple angles by a camera to obtain 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 of the leveling three-dimensional model is identified by a pre-trained recognition model; then the horizontality of the plane to be leveled is calculated, and if the horizontality of the plane to be leveled does not meet the preset horizontality (i.e., constraint conditions), based on the determined optimization objective function and constraint adjustment, the gradient descent algorithm is used for iterative solution to obtain the elongation scheduling result of the sling; then, the hydraulic system is controlled to adjust the length of the sling according to the elongation scheduling result, thereby completing the horizontal adjustment of the plane to be horizontalized without the conversion truss; wherein, 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, input the sample data into the initial neural network model for training until convergence, and obtain the recognition model; The beneficial effects of the above technical solution: Through the above technical solution, the non-conversion truss is automatically leveled before the non-conversion truss is connected with the preset corbel, thereby improving the connection effect between the non-conversion truss and the preset corbel; at the same time, the system automatically performs leveling, avoiding manual adjustment by construction personnel, and improving the safety of construction.

[0023] In one embodiment, the position of the preset bracket is adjusted according to the first type coordinates and the second type coordinates, and after the adjustment is completed, the second type coordinates are adjusted, including: S251: Select a second type of coordinate as a base point coordinate, and adjust the base point coordinate and the base point coordinate pair to the same horizontal line; wherein the base point coordinate pair is the first type of coordinate corresponding to the base point coordinate; S252: adjusting the data according to the relative angle and position of the base point coordinate pair and the first type of coordinates; S253: adjusting the relative position of the base point coordinates and the second type coordinates according to the adjustment data, and obtaining the adjusted second type coordinates after the adjustment is completed; The working principle of the above technical solution is as follows: after completing the horizontal adjustment, the construction personnel select the second-class coordinates of the connection point corresponding to a preset corbel as the base point coordinates, and then determine the base point pair coordinates in the first-class coordinates according to the base point coordinates, and adjust the position of the preset corbel through the two coordinates so that the two coordinates are on the same horizontal line, and then determine the relative angle and position between the base point pair coordinates and other first-class coordinates through three-dimensional coordinate calculation, and adjust the positions of the base point coordinates and other second-class coordinates according to the relative angle and position relationship between the base point pair coordinates and other first-class coordinates as adjustment data, so as to complete the one-to-one correspondence between the first-class coordinates and the second-class coordinates, that is, complete the position correspondence between the connection point of the current level and the connection point of the preset corbel; The beneficial effects of the above technical solution: Through the above technical solution, by adjusting the connection points of each docking level and the connection points of the preset corbels, the problem of deformation of the non-conversion truss due to unloading of the sling load and changes in the connection position of the docking level resulting in docking failure is avoided; the accuracy of docking between the non-conversion truss and the preset corbels is improved.
