[0038] Install following these steps:
[0039] (1) Make tapping holes on the side of the vertical frame 01 of the frame curtain wall corresponding to the installation position of the aluminum alloy grille adapter;
[0040] (2) Insert the EPDM rubber strip into the groove of the long side vertical frame;
[0041] (3) Use screws 08 to fix the upper part of the aluminum alloy grille adapter 02 to the curtain wall vertical frame, and add nylon gaskets 03 between the aluminum alloy grille adapter 02 and the curtain wall vertical frame 01.
[0042] (4) The lower part of the aluminum alloy grille adapter is inserted into the slot so that the notch 04 of the aluminum alloy grille adapter matches the slot of the long side vertical frame 07 of the combined aluminum alloy frame, and the combined aluminum alloy frame is snapped onto the curtain wall vertical frame 01 through the aluminum alloy grille adapter 02.
[0043] (5) Drill self-tapping screws 10 at the corresponding positions of waist holes 05 on the side of the long vertical frame 07 and the notch 04. This serves both as front and rear positioning and as an upward anti-detachment function. Open a tapping hole on the side of the rear end of the long vertical frame 07 and screw in screws 11 to hold the aluminum alloy grid adapter 02 in place and prevent the combined aluminum frame from shifting left and right.
