[0010] Through its structural design, during construction, first, the base plate is fixed to the concrete parapet wall and the concrete frame beam by chemical anchor bolts. Then, the aluminum alloy column is placed between two channel steels. After clamping the aluminum alloy column with the clamping device, the channel steel and the aluminum alloy column are connected by bolts to ensure the strength of the column under negative wind pressure. When the aluminum alloy column is fixed, the aluminum alloy cross beam is fixed between the aluminum alloy columns.

[0020] The roof surface 1 is fixedly connected to the concrete parapet wall 2. The concrete frame beam 4 is located above the concrete parapet wall 2, and the concrete frame beam 4 and the concrete parapet wall 2 are arranged at intervals. The concrete parapet wall 2 and the base plate 3 are fixedly connected by chemical anchor bolts, and the concrete frame beam 4 and the base plate 3 are fixedly connected by chemical anchor bolts. A clamping device 5 is installed on the base plate 3. The clamping device 5 is fixedly connected to the channel steel 6. The channel steel 6 and the aluminum alloy column 7 are fixedly connected by bolts. The aluminum alloy column 7 and the aluminum alloy cross beam 8 are fixedly connected by bolts. The square steel pipe 9 and the top end of the concrete frame beam 4 are fixedly connected by chemical anchor bolts.

The aluminum single plate 11 is fixedly connected to the square steel pipe 9, and the aluminum single plate 11 is fixedly connected to the aluminum alloy column 7. The toughened laminated glass 12 is fixedly connected to the aluminum alloy column 7.

[0021] In the present utility model, the clamping device 5 includes a double-axis lead screw 501 and a slider 502. The base plate 3 is rotationally connected to the double-axis lead screw 501. Both ends of the double-axis lead screw 501 are engaged with a slider 502 respectively. The slider 502 is slidably connected to the base plate 3, and the slider 502 is fixedly connected to the channel steel 6. By rotating the double-axis lead screw 501 on the base plate 3, the two sliders 502 are driven to move towards the middle. The movement of the sliders 502 towards the middle drives the channel steel 6 to move, and the two channel steels 6 complete the process of clamping and fixing the aluminum alloy column 7.

[0022] In the present utility model, a support plate 13 is provided at the top end of the concrete frame beam 4. The support plate 13 and the concrete frame beam 4 are fixedly connected by chemical anchor bolts. The support plate 13 and the square steel pipe 9 are fixedly connected by bolts.

[0023] In the present utility model, a neutral silicone weatherproof structural sealant 14 is provided at the butt joint of the aluminum single plates 11, at the butt joint of the toughened laminated glasses 12, and at the butt joint of the aluminum single plate 11 and the toughened laminated glass 12. The joint between the toughened laminated glass 12 and the aluminum single plate 11 is sealed by the neutral silicone weatherproof structural sealant 14 between the aluminum single plate 11 and the toughened laminated glass 12, preventing rainwater penetration and enhancing the integrity of the structure.

[0024] In this implementation scheme: During construction, first, the base plate 3 is fixed to the concrete parapet wall 2 and the concrete frame beam 4 through chemical anchor bolts. Then, the aluminum alloy column 7 is placed between two channel steels 6. After the aluminum alloy column 7 is clamped by the clamping device 5, the channel steel 6 and the aluminum alloy column 7 are connected by bolts to ensure the strength of the aluminum alloy column 7 under negative wind pressure. By rotating the double-axis lead screw 501 on the base plate 3, two sliders 502 are driven to move towards the middle. The movement of the sliders 502 towards the middle drives the channel steel 3 to move, completing the process of clamping the aluminum alloy column 7. After the aluminum alloy column 7 is fixed, the aluminum alloy cross beam 8 is fixed between the aluminum alloy columns 7. The end of the aluminum alloy column 7 is fixed to the square steel pipe 9 through an angle steel 10. The square steel pipe 9 is fixed to the concrete frame beam 4 through chemical anchor bolts, forming a complete curtain wall frame structure. The square steel pipe 9 is limited by the support plate 13 on the concrete frame beam 4 to enhance the stability of the square steel pipe 9. Finally, the aluminum single board 11 and the toughened laminated glass 12 are fixed on the aluminum alloy column 7 to complete the construction of the roof glass curtain wall. The neutral silicone weatherproof structural sealant 14 between the aluminum single board 11 and the toughened laminated glass 12 seals the joint between the toughened laminated glass 12 and the aluminum single board 11 to prevent rainwater penetration and enhance the integrity of the structure. During the normal use process after the construction of the present utility model is completed, when the wind speed increases, the wind generates suction above the roof 1, forming negative wind pressure. The toughened laminated glass 12 and the aluminum single board 11 of the curtain wall are subjected to outward tensile forces. These tensile forces will be transmitted to the aluminum alloy cross beam 8 and the aluminum alloy column 7. The aluminum alloy column 7 and the aluminum alloy cross beam 8 disperse and transmit the force to the channel steel 6, and finally the channel steel 6 transmits the force to the base plate 3. The base plate 3 transmits the force to the concrete parapet wall 2 and the concrete frame beam 4 through chemical anchor bolts, and finally transmits the negative wind pressure to the main structure.
