The outer walls of at least one side of the glass curtain wall stand column and the glass curtain wall beam are provided with connection devices respectively. The glass supporting devices and the connection devices are fixed in a matched mode, and the glass supporting devices are capable of supporting glass. Both one side wall of the glass curtain wall stand column and one side of the curtain wall beam are each provided with at least one fixing groove, and the fixing grooves are used for mounting glass adhesive tape. Both the outer side wall of the beam and the outer side wall of the stand column of a glass curtain wall are of the smooth structure, the outer wall of one side face is provided with the corresponding connection device, and the connection devices are used for being fixedly connected with other components in a matched mode. According to the curtain wall structure, the structure that both a stand column and a beam of a bright frame glass curtain wall are provided with overall protrusions is changed, universality of a bright frame curtain wall structure and a hidden frame curtain wall structure is achieved, the same setting is adopted for the main structure, only the glass supporting devices need to be replaced, and switching of the bright frame curtain wall and a hidden frame curtain wall can be achieved.
