During construction, use positioning instruments to recheck the positions of the corner points to ensure their accuracy. A support 13 is installed at these corner points.

[0053] Third step: Install the corresponding glass units 2 within the square formed by the four corner points. An aluminum alloy crossbeam 11 is provided at the junction between the upper and lower glass units 2. There are several threaded holes on the extension line of the aluminum alloy crossbeam 11.

Inner lining with 180 mm thick thermal insulation rock wool and 80 mm thick sound-absorbing glass wool for thermal insulation.

[0056] On the left and right sides of the glass unit 2 are columns, which are made of fluorocarbon-coated steel. On the upper and lower sides of the glass unit 2 are aluminum alloy crossbeams 11. The columns and the aluminum alloy crossbeams form a stress-bearing framework, and then install the glass unit 2. The stress-bearing method and structural form are such that the load is transmitted from the glass unit 2 to the stress-bearing framework. When one of the glass units 2 is damaged, only need to loosen the pressing plate 12 corresponding to that glass unit 2, and then tighten it again after replacement, so that the pressing plate 12 presses the glass unit 2 on the stress-bearing framework.

[0057] At the corner points of the junctions between the glass units 2, there are supports 13. On the supports 13, there are baffles which divide the supports 13 into two equal left and right parts.

And each bolt group needs to be equipped with two flat washers, one spring washer and one nut. Due to the existence of the first strip-shaped groove 17, the position of the keel 14 can be adjusted left and right. Due to the existence of the second strip-shaped groove 18, the position of the keel 14 can be adjusted inwards and outwards. After the position adjustment is completed, the fixing bolts are fixed. The keel 14 is fixedly installed on the bottom plate 16, and then the upper cover 15 is closed and connected, and the gap between the upper cover 15 and the bottom plate 16 is filled with a glue unit.

[0058] The performance of the curtain wall is tested as follows:

The standard value of the wind load at the corner of the building elevation of 36.676m is WK = 1.677 KN / m². Therefore, the wind pressure resistance performance of the curtain wall in this project is grade 2.

[0060] 2. Airtightness performance: The airtightness performance refers to the performance of the curtain wall with its opening part closed to let air through under the action of wind pressure. Therefore, the airtightness performance of the curtain wall in this project is grade 3.
