[0038] Furthermore, a connecting arm 412 is provided at the other end of the aluminum alloy pressure plate body 41 . The connecting arm 412 is fixedly connected to the aluminum alloy outer buckle cover 44 through a first bolt 45 .

A 4 mm thick aluminum alloy beam angle code is provided in the aluminum alloy beam 20 for connecting to the aluminum alloy column 1. At the same time, a glass sub-frame is provided on the aluminum alloy beam 20 for pasting and fixing the glass panel 3.

[0048] When installing the overall structure of the curtain wall at any angle, first install and fix the aluminum alloy column 1, then use the ball head 21 to rotate the aluminum alloy pad frame 2 around the arc groove 12 of the aluminum alloy column 1, so that the second rubber strip 221 of the second rubber strip slot 22 of the aluminum alloy pad frame 2 is parallel to the glass panel 3, and then use the M5x25mm stainless steel locking bolt 5 to fix the aluminum alloy pad frame 2 and the aluminum alloy column 1. Subsequently, the glass panel 3 is pressed into the outside of the aluminum alloy gasket frame 2, and a slot 111 is connected to the middle of the front end of the aluminum alloy column 1. The hard PVC pad 6 is pressed into the position of the slot 111, and then the aluminum alloy pressure plate assembly 4 is pressed against the outside of the hard PVC pad 6. At the same time, the connecting arms 412 on both sides of the aluminum alloy pressure plate assembly are rotated so that the third rubber strip 8 of the third rubber strip slot 413 in the middle of the connecting arm 412 is parallel and close to the glass panel 3. Then the aluminum alloy pressure plate clip 43 is pressed into the middle of the two aluminum alloy pressure plate bodies 41. Finally, the aluminum alloy pressure plate assembly 4 and the slot 111 at the front end of the aluminum alloy column 1 are connected and fixed by the M5x40mm stainless steel second bolt 7, and then the aluminum alloy outer buckle cover 44 is fixed on the connecting arms 412 on both sides of the aluminum alloy pressure plate body 41 to complete the curtain wall installation at any angle.
