[0067] The large-span special-shaped curved curtain wall system, when the curved curtain wall needs to be installed, multiple main support columns 1 are fixed at the connection points of multiple curtain wall glasses 4, and the fixing tube 29 is installed on the outer wall of the main support column 1 through the fixing assembly. The specific operation is to press the two arc-shaped connecting frames 6 from both sides of the main support column 1 tightly, and then insert the two ear plates 26 on one side into the rectangular hole 38 from top to bottom. At this time, multiple fixing screws 37 are inserted into the corresponding No. 1 threaded hole 36 and No. 2 threaded hole 39, and the fixing process of the fixing tube 29 is completed by cooperating with the nut 41;

[0068] When the fixing tube 29 is installed, the position of the U-shaped plate 13 is at the connection point of the four curtain wall glasses 4. At this time, the sides of the four curtain wall glasses 4 are all provided with side connecting blocks 9, and two adjacent side connecting blocks 9 are connected by the I-shaped plate 5.

When the curtain wall glass 4 rotates, the rain shield 8 cooperates with the lower connecting block 3 to rotate a certain angle, which can improve the sealing performance of the device, and the setting of the sealing block 10 and the rubber strip 11 can further improve the sealing performance of the device;

[0070] When the adjustment is completed, the annular sleeve 12 is rotated, and the annular sleeve 12 moves forward on the thread on the fixed cylinder 29. Due to the setting of the arc groove 40, the two pressing plates 23 are close to each other, and the pressing plates 23 drive the two sliding blocks 32 to approach each other. The sliding blocks 32 enter the interior of the sliding groove 34 and continuously squeeze the No. 2 spring 33.

Install curtain wall glass (4) and connecting parts: Installing side connection blocks (9) on the side of the curtain wall glass (4), and connecting adjacent side connection blocks (9) via an I-shaped plate (5); installing an upper connection block (2) and a lower connection block (3) on the top and bottom of the curtain wall glass (4), respectively; S4. Adjust the angle of curtain wall glass (4): Rotate the adjusting screw rod (16) to drive the abutting plate (21) to move horizontally, thereby pushing one side of the curtain wall glass (4) to move, so that it drives the lower connecting block (3) to rotate around the fixed axis (7); The sliding plate (22) is pressed against the other side of the curtain wall glass (4), moves with it and presses the first spring (19), thereby ensuring the stability of the curtain wall glass (4); S5. Adjust the sealing: When the curtain wall glass (4) rotates, the support block (30) and the support rod (14) drive the rotating shaft (27) to rotate in the fixed cylinder (29); S6, lock the adjustment position: The annular sleeve (12) is rotated to make it move forward on the fixed cylinder (29) by threading; the design of the arc groove (40) allows the two pressing plates (23) to approach each other, driving the clamping rod (35) to be inserted into the first clamping hole (18) and the second clamping hole (31), pressing against the outer wall of the rotating shaft (27), and locking the tilted position of the curtain wall glass (4).
