The curtain wall double-track lifting system is provided with a plurality of hoops 11 at intervals on the main structure 20 of the curtain wall, and the hoops 11 include a top member 111 and two side members 112 respectively provided on both sides of the top member 111 to respectively hold the top and both sides of the main structure 20, and the lower end of the side member 112 is penetrated by a screw 113 to make the hoops 11 hold the main structure 20 tightly, so as to clamp the main structure 20, and the outer side of the upper surface of the top member 111 of the hoops 11 is installed with a cantilever beam 12 through a supporting column 14, and an ear plate 15 is provided on the side member 112 close to the inner side of the top member 111, and the ear plate 15 is connected to the cantilever beam 12 through a diagonal member 16 to support the connection between the main structure 20 and the cantilever beam 12, so that the main The structure 20 is stably connected to the cantilever beam 12, and the supporting column 14 is located on the outside of the upper surface of the top component 111 to achieve the purpose of maximum rotational eccentricity, and the diagonal member 16 is located on the inside of the hoop 11, which can maximize the distance between the supporting column 14 and the diagonal member 16, so that the connection between the cantilever beam 12 and the main structure 20 is more stable, and the hoop 11 can be prevented from causing the main structure 20 to flip, and the top component 111 can be prevented from being compressed and deformed. The track mechanism 13 is horizontally arranged at one end of the cantilever beam 12 away from the ear plate 15 for the installation of the lifting device 30. During the installation of the entire system, there is no need to perform secondary welding on the main structure 20 of the curtain wall. It is green and environmentally friendly, easy to install, stable and reliable, and removable for easy maintenance and replacement.

[0028] Specifically, in this embodiment, a diagonal brace 17 is fixedly connected between the support column 14 and the cantilever beam 12 to support the support column 14 and the cantilever beam 12, so that the support column 14 and the cantilever beam 12 are firmly connected, thereby making the clamp 11 and the cantilever beam 12 firmly connected, improving the rigidity of the curtain wall double-track lifting system, reducing the vertical deformation, and increasing the anti-overturning rigidity of the curtain wall double-track lifting system. Preferably, the angle between the diagonal brace 17 and the support column 14 and the angle between the diagonal brace 17 and the cantilever beam 12 are both 45°.

[0029] Specifically, in this embodiment, the cantilever beam 12 and the track 131 are both I-beams to ensure the connection strength of the cantilever beam 12. The cross-sectional size of the cantilever beam 12 is larger than the cross-sectional size of the track 131 to provide sufficient rigidity. The cantilever beam 12 is welded and fixed to the support column 14, and the support column 14 is a steel pipe. The cantilever beam 12 and the support column 14 are welded by fillet welds.

[0030] Specifically, a connecting plate 121 for installing the track 131 is provided on the end of the cantilever beam 12 away from the ear plate 15, and the track 131 is installed on the connecting plate 121 by bolts 101. The connection between the track 131 and the cantilever beam 12 is achieved by the bolts 101, and the cantilever beam 12 does not need to provide additional internal stress. The connecting plate 121 is welded to the bottom of the cantilever beam 12, and bolt holes are opened on the connecting plate 121 for the bolts 101 to pass through and fix. Preferably, a lower steel plate 132 is provided between the track 131 and the connecting plate 121, and the lower steel plate 132 is welded to the track 131, and holes corresponding to the bolt holes are opened on the lower steel plate 132 for the bolts 101 to pass through and fix.

[0031] Specifically, a stiffener 122 is fixedly connected between the main body of the cantilever beam 12 and the connecting plate 121 to support the cantilever beam 12 and the connecting plate 121, so that the cantilever beam 12 and the connecting plate 121 are stably connected. The cantilever beam 12 is located in the center of the connecting plate 121, and the stiffeners 122 are respectively welded and fixed between the two sides of the main body of the cantilever beam 12 and the two sides of the connecting plate 121.

[0032] Specifically, the diagonal member 16 includes an angle steel 161, one end of which is connected to the ear plate 15, and the other end of which is connected to the cantilever beam 12. Both ends of the angle steel 161 are respectively connected to the ear plate 15 and the cantilever beam 12 by fixing bolts 102, so that the angle steel 161 can be easily disassembled and replaced.

[0033] Specifically, the diagonal member 16 also includes a steel cable 162, one end of which is connected to the ear plate 15, and the other end of which is connected to the cantilever beam 12, and the angle between the steel cable 162 and the side member 112 is greater than the angle between the angle steel 161 and the side member 112. The angle steel 161 has a greater rigidity than the steel cable 162 and is easier to tighten, and the angle steel 161 is closer to the hoop 11. As the main force-bearing diagonal member, the arrangement of the steel cable 162 can tighten the hoop 11 in time after the angle steel 161 fails to avoid flipping between the cantilever beam 12 and the main structure 20, thereby improving the stability of the curtain wall double-track lifting system. The diagonal angles of the angle steel 161 and the steel cable 162 are inconsistent to avoid unbalanced force on both sides of the hoop 11. The two ends of the steel cable 162 are connected to the ear plate 15 and the cantilever beam 12 respectively through the hook 103, which can facilitate the removal and replacement of the steel cable 162. The ear plate 15 is provided with two through holes for the installation of the fixing bolt 102 and the hook 103 respectively. Preferably, the cantilever beam 12 is provided with a connecting support plate 123 connected to the other end of the angle steel 161 and the other end of the steel cable 162 respectively at one end close to the ear plate 15. The connecting support plate 123 is provided with a through hole for the installation of the fixing bolt 102 or the hook 103.

[0034] Specifically, the upper ends of the support columns 14 are connected to the two sides with beams 18, and the adjacent support columns 14 are fixedly connected with scissor braces 19 to improve the lateral rigidity of the curtain wall double-track lifting system and ensure the stability of the curtain wall double-track lifting system. The adjacent support columns 14 are respectively connected to the two ends of the beam 18. The side of the support column 14 is provided with a first ear plate, and the end of the scissor brace 19 is provided on the first ear plate by a connecting bolt to achieve a stable connection between the adjacent support columns 14.

The cantilever beams are stably connected, and the supporting columns are located on the outside of the upper surface of the top component to achieve the maximum rotational eccentricity, while the diagonal member is located on the inside of the hoop, which can maximize the distance between the supporting columns and the diagonal member, making the connection between the cantilever beam and the main structure more stable, and can prevent the hoop from causing the main structure to flip, and avoid the top component from being compressed and deformed. The track mechanism is horizontally arranged at the end of the cantilever beam away from the ear plate for the setting of the lifting device.
