Preferably, the main building structure 1 is a frame beam, and the grating support 9 is suspended on the outside of the glass curtain wall via the first connecting member 6, the second connecting member 7, and the diagonal brace. The suspended grid structure can reduce the space occupied by the lower part and ensure the aesthetic appearance.

[0042] In this embodiment, the diagonal brace further includes a fourth fixing assembly 15 and two clamping plates 25 connected to the diagonal brace body 8 . The second connecting member 7 is inserted between the two clamping plates 25 and fixed by the fourth fixing assembly 15 .

[0043] The decorative sleeve 10 can be made of decorative aluminum plate, which is wrapped around the outside of the diagonal brace body 8 and has a shielding effect on the diagonal brace connecting plates 26 and the splints 25 at both ends of the diagonal brace body 8. The appearance of the decorative sleeve 10 needs to be compatible with the grating support 9 and the grating. Structural glue is applied to the connection gap of the end of the decorative sleeve 10 to improve the connection stability. The color of the structural glue is adapted to ensure the appearance is beautiful.

[0044] In this embodiment, the grating blade portion 11 is connected to the outer flange plate of the support body 21, and the first connecting member 6 can pass through the top inner flange plate of the corresponding support body 21 to be inserted into the internal cavity of the web of the support body 21. The first connecting member 6 is detachably connected to the web of the corresponding support body 21 by bolts.

[0045] On the other hand, the present invention also provides a construction method of a glass curtain wall grid structure, comprising the following steps:

[0046] A plurality of grating supports 9 are installed at intervals along the horizontal direction on the outer edge of the glass curtain wall. Each grating support 9 is arc-shaped and gradually moves away from the glass curtain wall from top to bottom. Each grating support 9 is connected to the glass curtain wall through a first connecting member 6 and a diagonal brace, that is, each grating support 9 is suspended on the glass curtain wall. A plurality of gratings are installed at intervals along the vertical direction on the grating support 9 to form a grid-like grating structure.

[0047] In one construction scenario, the glass curtain wall is a curved surface, and each grating is composed of multiple grating parts 11 horizontally spliced ​​into an arc to form a grid-like grille structure that is curved in both vertical and horizontal directions. Preferably, the two ends of each grating part 11 are respectively connected to adjacent grating supports 9.

[0048] When multiple layers of grille units are to be installed, the above steps are repeated, and each grille unit is suspended in a stacked manner in the vertical direction. Specifically, at least a portion of the upper portion of the grating support 9 provided on the lower grille unit is stacked with the lower portion of the grating support 9 provided on the upper grille unit.

[0049] Compared with the traditional grille structure parallel to the curtain wall, this embodiment can achieve a multi-layer curved gradient effect; the components of the grille structure are designed with cavities in many places to reduce the deadweight; the structural strength is improved by using diagonal braces and reinforcing components to ensure the stability of the curved grille structure; the grille structure is firmly connected to the glass curtain wall, and adopts concealed connections and various buckle cover structures to avoid exposing the bolt nodes. The curve transition of the grille structure is natural, the connection is smooth, and the aesthetics are guaranteed; modular installation is convenient and the construction period can be shortened.
