The step of "fixed-point positioning and welding of the butt joint base" specifically includes the following steps: Step 1: locating the positions of the vertical and horizontal cables; Step 2: finding the position of the butt joint base on the embedded steel plate and marking it with a line, wherein the position of the line coincides with the position of the center line of the butt joint base; Step 3: determining whether the butt joint base is perpendicular to the concrete structure and calculating the vertical deviation thereof through a vertical laser positioner, if the vertical deviation is less than 5mm, welding can be performed, if the vertical deviation is greater than 5mm, welding cannot be performed, the positional relationship between the butt joint base and the concrete structure is adjusted until the vertical deviation between the butt joint base and the concrete structure is less than 5mm; Step 4: welding the butt joint base.

9. The method of claim 6, wherein the glass is installed and positioned in the large-span cable wall. The step of "pre-tensioning construction and verification of the cable" specifically includes: Force measurement of the vertical cable: Taking points at different three elevation positions in an average section; Measuring the force of each vertical cable at the same elevation and recording the results; Comparing the measurement results of each vertical cable to determine the force difference of each vertical cable at the same elevation; Re-adjusting the tension of the cable, tightening the cable if the tension value is less than the design value, and unloading the cable if the tension value exceeds the design value, so that the tension values of the cables at the same elevation are equal and the difference is not more than 5KN.

10. The method of claim 9, wherein, The step of "glass positioning and hoisting" specifically includes the following steps: First step: lifting the glass using hoisting machinery; Second step: aligning the glass with the position of the butt joint claw; Third step: the infrared laser range finder on the edge plate of the butt joint claw emitting infrared laser to the glass; Fourth step: when the infrared laser reaches the glass, it is reflected back to the infrared laser range finder, and the infrared laser range finder calculates the distance between the butt joint claw and the glass; Fifth step: the infrared laser range finder uploads the measured data to the upper computer; Sixth step: according to the data received by the upper computer, the hoisting machinery adjusts the distance between the glass and the butt joint claw. ​
