Figures 1-4 illustrate a cross-brace grille curtain wall structure of an embodiment of the present application, including a curtain wall cross beam 100, a grille 200, and a T-connector 300. The T-shaped connector 300 includes a first side 301 and a second side 302 that are perpendicular to each other, wherein the first side 301 is located midway between the second side 302.

The adjacent grid 200 may be adjusted by adjusting its distance to the first side 301 of the T-connector 300, thereby enabling adjustment of the distance of the adjacent grid 200. In this way, in the whole installation process, different grids 200 have adjustment spaces, thereby facilitating site construction and reducing installation difficulty. While adjacent grills 200 are secured to the curtain wall cross beam 100 with the same T-connector 300, also simplifying installation.

In some embodiments, as shown in fig. 1-4 and 9, the grid 200 includes vertical sides 201, and when installed, the first side 301 of the T-shaped connector 300 is located between the vertical sides 201 of adjacent grids 200, and two mounting wings of the T-shaped connector 300 respectively abut against end surfaces 2011 of the vertical sides 201 of the corresponding grids 200. The interference of the second side 302 of the T-connector 300 with the end face 2011 of the grid 200 further facilitates a positioning match during installation such that the first side 301 of the T-connector 300 and the third mounting hole 2012 of the vertical side 201 of the grid 200 can easily correspond, thereby reducing installation difficulty.

In some embodiments, as shown in fig. 1-11, the first side 301 of the T-connector 300 includes a first mounting hole 3011 and the second side 302 of the T-connector 300 includes a second mounting hole 3021. The vertical side 201 of the grid 200 includes a third mounting hole 2012. And the curtain wall cross beam 100 includes a fifth mounting hole. A bolt assembly may pass through the first mounting hole 3011 and the third mounting hole 2012 to fixedly connect the grid 200 with the T-connector 300. The bolt assembly may pass through the second mounting hole 3021 and the fourth mounting hole 101 to fixedly connect the T-shaped connector 300 and the curtain wall cross member 100. The shape of the mounting hole may take a variety of forms including, but not limited to, round hole and bar.

In some embodiments, as shown in FIGS. 1-2, the curtain wall cross beam 100 includes a top surface and a bottom surface that are parallel to each other. The installed curtain wall cross member 100 has its top and bottom surfaces perpendicular to the outer surface of the building.

When installed, the mounting ferrules 402 are inserted into the mounting cavities 102 of the curtain wall cross beam 100 along the ferrule-based slots of the curtain wall cross beam 100. A set of bolt assemblies may be passed through the curtain wall cross beam 100 and the mounting insert 402 to secure the two. Another set of bolt assemblies may then be passed through the mounting ferrule 402 and the mounting ear plate 401 to secure the mounting ferrule 402 to the building. So that the curtain wall cross member 100 is fixedly coupled to the building through the first coupling assembly 400. Since the grille 200 is secured to the curtain rail 100 by the T-shaped connector 300, the grille 200 is secured to the building by the engagement of the first connector assembly 400. The mounting ferrule 402 is provided with a mounting plate 4021 adapted to the mounting ear plate 401, and an adapted mounting through hole is provided between the mounting plate 4021 and the mounting ear plate 401.

The limiting structure 503 includes a second through slot 5031 adapted to the first through slot 104 and the pull rod 501. During installation, the limiting structure 503 is clamped in the limiting clamping groove 105 of the curtain wall beam 100, the pull rod 501 passes through the through grooves 104 and 5031 of the curtain wall beam 100 and the limiting structure 503, the mutual interference between the pull rod 501 and the first through groove 104 limits the first radial position (X direction shown in fig. 10) of the curtain wall beam 100 relative to the pull rod 501, and the limiting structure 503 fixed on the curtain wall beam 100 can limit the curtain wall beam 100 and specifically limits the second radial position (Y direction shown in fig. 10) of the curtain wall beam 100 relative to the pull rod 501. The curtain wall cross beam 100 is fixedly installed on the tie rod 501 by the cooperation of the tie rod 501, the pallet 502 and the limiting structure 503 of the second connection assembly 500, thereby achieving a fixed connection with the building.
