The invention relates to an all-glass
curtain wall support structure. The height of a connecting part can be adjusted by adjusting the position of a fixed part in the vertical direction of a long-
waist-shaped hole or a long-stripe-shaped hole in a
washer, the
fixed position between the connecting part and a glass rib can be adjusted to certain extent according the
fixed position between a glass panel and the connecting part, the problem that the height of the
fixed position between the connecting part and the glass rib is not matched with that of the fixed position between the connecting part and the glass panel due to
machining errors is solved, fragmentation of the glass rib or the glass panel is prevented, and the safety of the glass rib and the glass panel is guaranteed. In addition, due to the fact that the fixed part is located in the long-
waist-shaped hole or the long-strip-shaped hole, when the the glass
curtain wall is deformed slightly under the wind action, the fixed part still can not make contact with the inner walls of the top and the bottom of the
washer, the gravity of the glass panel can not be transmitted to the glass rib along the fixed part, the gravity of the glass panel is all borne by a pull rod or an inhaul cable all the time, therefore, the fragmentation of the glass rib is prevented, and the safety of the glass rib is protected.
