The opening leaf structure has the advantages that an opening leaf body fixing mode is changed, hardware is saved, production cost is lowered, the opening leaf structure is convenient to install, and a phenomenon that rain leaks into indoor space from a gap between the top of the opening leaf body and the glass curtain wall cross beam can be effectively avoided when the opening leaf body is opened; the inner-side glass and the outer-side glass of the big and small pieces of hollow glass are respectively spliced and fixed with the opening leaf body, and hidden dangers that the hollow glass integrally falls since the inner-side glass is broken can be effectively avoided; the glass supporting strip performs a safety protection function, so that a risk that the hollow glass falls from a frame when structural adhesive fails is effectively avoided.
