[0043] Furthermore, the opening sash assembly includes a window sash outer frame 34, and the window sash outer frame 34 is provided with an opening sash outdoor decorative panel 35, an opening sash vacuum insulation panel 36, an opening sash thermal insulation rock wool 37 and an opening sash indoor decorative panel 38 in sequence from the outdoor side to the indoor side.

[0044] When the opening fan assembly is closed, there is also a heat-insulating sealing structure between the window fan outer frame 34 and the opening fan profile frame 33 and plays a corresponding role. Combined with the setting of the opening fan vacuum insulation panel 36 and the opening fan thermal insulation rock wool 37, the thermal performance of the opening fan can be greatly improved; when ventilation is needed, the opening fan assembly can be opened. Due to the existence of the perforated aluminum plate 32 on the facade, it cannot be seen from the outside, the facade structure remains unchanged, and the external structure is more beautiful.

[0045] In some embodiments, the standard unit panels can be spliced ​​and used in sequence to form a continuous V-shaped folded surface structure, and the curtain wall male columns and the curtain wall female columns can be connected and assembled together.

[0046] Specifically, Figure 6As shown, one side of the curtain wall public column 4 is provided with a glass connector that can be connected to the indoor protective glass railing 3, and an external force glass connection groove that can be connected to the external facade glass panel 2; the other side (at the mating surface) of the curtain wall public column 4 is provided with a plurality of bent plug-in connection arms 401, and the side (at the mating surface) of the curtain wall female column 7 is provided with a plug-in connection groove 701 or a plug-in buckle 702, which can be used to connect the plug-in connection arm 401, and the curtain wall public column 4 and the curtain wall female column 7 are also provided with a relative column connection groove 39, and a column connection member 40 is provided in the column connection groove 39, and a sealing connection member 41 is connected between the relative column connection members 40. By setting in this way, the curtain wall public column 4 and the curtain wall female column 7 can be assembled together in a sealed manner.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
