[0002] In some high-rise buildings, in order to maintain the integrity and aesthetics of the building, the building facade is usually sealed with a curtain wall structure, including an aluminum alloy curtain wall; since the aluminum alloy curtain wall acts as a wall of the building, the thermal insulation performance of the curtain wall has a great influence on the thermal insulation performance of the entire building; at present, the thermal insulation performance of most aluminum alloy curtain wall glass cannot meet the requirements of passive buildings.

[0003] In the prior art, a Chinese utility model patent with announcement number CN 207776179 U and announcement date 2018.08.28 discloses an assembled ultra-low energy consumption aluminum alloy curtain wall glass, including an aluminum alloy profile, an auxiliary frame, an insulating glass, a heat-insulating tie bolt, a supporting and fixing structure, and an outer guard plate. The aluminum alloy profile is fixedly connected to one end of the heat-insulating tie bolt, the auxiliary frame is connected to the insulating glass by structural adhesive, the auxiliary frame is surrounded by a low-density EPDM rubber strip, and a sealing rubber strip is arranged on the outer side of the low-density EPDM rubber strip to form a sealed whole. The heat-insulating tie bolt is arranged at the joint of the insulating glass, the supporting and fixing structure is fixedly connected to the other end of the heat-insulating tie bolt, the supporting and fixing structure is clamped with the outer guard plate, and the heat-insulating tie bolt is sleeved with a heat-insulating foam strip. Although the patent avoids the formation of a point thermal bridge through the setting of the heat-insulating tie bolt, effectively blocks the indoor and outdoor heat transfer, and reduces the energy consumption, it still cannot meet the isothermal transition of the passive window.

[0026] like Figure 1 and Figure 2 As shown, in Example 2, a passive aluminum alloy curtain wall, the heat insulation plug-in 1 4 and the heat insulation plug-in 2 14 are both PVC material heat insulation plug-ins, and glass edge filling foam 2 is provided between the heat insulation plug-in 1 4 and the curtain wall glass 3, and between the heat insulation plug-in 1 4 and the passive window, and glass edge filling foam 2 is provided between the heat insulation plug-in 2 14 and the curtain wall glass 3.

[0028] The other structures are the same as those in Example 1.

[0029] like Figure 1~Figure 3 As shown, Example 3 is a passive aluminum alloy curtain wall, the external fasteners include a cover plate 5 and a pressure plate 6, the cover plate 5 is connected to the heat insulation plug-in 4, the pressure plate 6 is mounted on the cover plate 5 and a long bolt is provided on the pressure plate 6, the long bolt passes through the pressure plate 6 and the cover plate 5 to fix the heat insulation plug-in 4 to the vertical main column 1, and a buckle plate 7 is also provided on the cover plate 5 and the pressure plate 6.

The long bolts pass through the pressure plate 6, the cover plate 5 and the insulation plug-in 4 and are connected with the vertical main column 1. The pressure plate 6, the cover plate 5, the insulation plug-in 4 and the vertical main column 1 are connected into an integral structure. The buckle plate 7 is clamped with the pressure plate 6 and the cover plate 5. The buckle plate 7 is used to protect the long bolts to prevent the long bolts from being exposed for a long time and being corroded.

[0034] S1: Cut and drill holes for the main columns, beams 13 and other profiles according to the conventional aluminum alloy curtain wall scheme, install the rubber strips involved on the profiles in place, and make passive windows. The interior of the passive window insulation strip cavity and the glass edge need to be filled with EVA foam material.

[0035] S2: Fix the vertical main columns according to the design drawings using galvanized steel plates and L-angles. When fixing, ensure the column gap size accuracy and be completely vertical. Then install the crossbeam 13 on the vertical main columns using spring pins.

[0036] S3: Install the heat insulation plug-in, place the glass support strips 15 with the rubber pads 17 attached at a distance of 150 mm from the ends and a distance of 300-500 mm between each two adjacent glass support strips 15, and stick the glass edge with foam filling to the heat insulation plug-in.
