[0037] Compared with the prior art, the beneficial effects of the present invention are as follows. Through the stress detection array arranged in the steel bar positioning frame, the stress distribution condition during the positioning process of the positioning steel bars by the steel bar positioning frame during the installation process is monitored in real time, which is beneficial to timely understanding and mastering the force condition during the positioning process. Determine the torque of the steel bar positioning frame according to the stress distribution condition, and compare it with the maximum allowable torque to judge the safety and stability of the positioning process, so as to avoid damage or deformation of the positioning frame caused by excessive torque. By detecting the stress change evaluation values before and after adjustment, evaluate the influence of the adjustment measures on the force condition of the steel bar positioning frame, provide an important reference for further optimizing the construction, determine the maximum number of adjustments of the steel bar positioning frame according to the force feedback sensitivity, improve the construction efficiency on the premise of ensuring the construction quality and safety, reduce unnecessary adjustments and rework, and contribute to improving the construction quality and construction efficiency of the positioning steel bars in the transfer layer.

[0038] In particular, by setting multiple force-bearing plates and a detection array, the stress distribution of the steel bar positioning frame during the positioning of the positioning steel bars is detected comprehensively, and more comprehensive and accurate stress data are obtained. The force-bearing plates are sequentially connected to form a square frame, improving the structural stability and load-bearing capacity of the steel bar positioning frame, which is conducive to ensuring the construction quality and safety. The resultant force of each force-bearing plate is obtained through the detection array, and the stress condition of the steel bar positioning frame under different construction conditions is quantitatively evaluated, providing a data basis for subsequent judgment of whether the steel bar positioning frame is deformed.

[0039] In particular, by evenly distributing four stress sensors on the first force-bearing plate at a first interval, the stress distribution on the first force-bearing plate is comprehensively detected, and more accurate stress data are obtained. A stress sensor is respectively set at the position where the stress sensors at the left and right ends of the first force-bearing plate are spaced at a second interval, strengthening the monitoring of the edge stress of the force-bearing plate, which is conducive to timely discovering and solving potential stress concentration problems. By setting the second interval to be smaller than the first interval, more refined monitoring is carried out on the area that is more sensitive to stress changes, improving the accuracy and reliability of stress detection.

[0040] In particular, by determining the stress value and stress direction received by each stress sensor according to the output signals of the six stress sensors, more comprehensive and accurate stress data are obtained. The vector synthesis value of the stress values of the six stress sensors is calculated according to the stress value and stress direction, quantitatively evaluating the overall stress condition on the first force-bearing plate, providing a basis for analyzing and predicting the stress feedback sensitivity. The vector synthesis value is used as the first resultant force, intuitively understanding the stress condition on the first force-bearing plate, which is convenient for monitoring and adjusting the construction process of the positioning steel bars.

[0041] In particular, by comparing the magnitudes of the first resultant force, the second resultant force, the third resultant force, and the fourth resultant force, it is judged whether there is a torque on the steel bar positioning frame, thereby understanding the installation quality and stress condition of the positioning frame. The formula P = ΔF × L / 2 is used to calculate the torque, quantitatively evaluating the torque magnitude of the steel bar positioning frame, providing a basis for further optimizing the construction and adjusting the positioning frame. By determining the torque, potential construction problems are timely discovered and solved, improving the construction quality of the positioning steel bars and the safety of the construction process.

[0042] In particular, by performing stress detection on the adjusted steel bar positioning frame, the influence of the adjustment measures on the stress condition of the positioning frame is understood, and the adjustment effect is evaluated. By comparing the stress values before and after adjustment and calculating the difference, the magnitude and direction of the stress change are quantitatively evaluated, providing a basis for further optimizing the construction and adjusting the positioning frame. By using the difference as the stress change evaluation value, the influence degree of the adjustment measures on the stress condition of the steel bar positioning frame is intuitively understood, which is convenient for monitoring and adjusting the construction process of the positioning steel bars.

[0043] In particular, by establishing a rectangular coordinate system with the stress change evaluation value as the abscissa and the stress feedback sensitivity as the ordinate, the relationship and trend between historical data are intuitively displayed, providing a basis for selecting a regression model. The historical stress change evaluation values and their corresponding historical stress feedback sensitivities are plotted as points in the rectangular coordinate system to clearly understand the data distribution and change trend, which helps to discover potential laws and abnormal data. By connecting adjacent points and selecting a regression model, fitting and regression analysis are performed on the historical data to obtain a regression equation and establish a prediction model, providing a basis for predicting future stress feedback sensitivities.

The method for positioning and constructing the assembled transfer layer reinforcement bars according to claim 7 is characterized in that: The stress change evaluation values ​​before and after the adjustment include: Determine the adjusted stress value of each stress sensor through the output signals of the six stress sensors arranged on each positioning plate of the adjusted steel bar positioning frame; A difference is calculated between the adjusted stress value and the stress value before adjustment, and the difference is used as a stress change evaluation value.

9. The method for positioning and constructing the assembled transfer layer reinforcement bars according to claim 8, characterized in that: Predicting the force feedback sensitivity of the steel bar positioning frame includes: A prediction model of force feedback sensitivity is established according to the historical stress change values ​​and their corresponding historical force feedback sensitivity in the database; The stress change evaluation value is input into the prediction model to obtain the actual force feedback sensitivity.

10. The method for positioning and constructing the assembled transfer layer reinforcement bars according to claim 9, characterized in that: The prediction model of force feedback sensitivity is established based on the historical stress change values ​​in the database and their corresponding historical force feedback sensitivity, including: Establish a rectangular coordinate system with stress change evaluation value as the horizontal coordinate and force feedback sensitivity as the vertical coordinate; plot the historical stress change evaluation value and its corresponding historical force feedback sensitivity in the form of points. In the rectangular coordinate system; Connect two adjacent points and select a regression model based on the trend of the connected graph; The historical stress change evaluation value and its corresponding historical force feedback sensitivity are fitted according to the regression model to obtain a regression equation, and the prediction model based on the regression equation is established.
