With the rapid development of building curtain walls, the appearance of the curtain walls is also diversified more and more. The wide-span inclined glass curtain wall is also applied more and more in public buildings, such as stadiums, exhibition halls, airports and the like.

The large-span inclined glass curtain wall is mainly characterized by large span, and compared with the vertical and vertical traditional glass curtain wall, the bending deformation of the vertical column is larger, and the part of external force causing the increase of the bending deformation (deflection) mainly refers to the self weight of a supporting structure and curtain wall materials and the bending deformation generated by the external force acting in the vertical direction. Therefore, compared with the traditional glass curtain wall, the inclined glass curtain wall has more complex stress on the supporting structure, and has larger requirement on the bearing capacity of the supporting structure for the inclined curtain wall with the same span. The traditional large-span inclined glass curtain wall upright post generally adopts welded section steel or welded section steel and standard aluminum alloy section steel, is usually single span and does not span floors. The stand adopts the connection form of seat down of drawing on, and its lower part adopts the articulated form of cover heart connection to fix on burying the board generally, and upper portion generally sets up vertical slotted hole on the connecting plate, adopts bolted connection to guarantee that the stand has vertical certain flexible function. These conventional approaches have the following major disadvantages: (1) the cross-sectional dimension of the upright post is relatively large, the weight is heavy, the installation is inconvenient, and the cost is not economical. (2) The upright post is not adjustable in the horizontal direction, so the structure with higher requirement on the horizontal installation precision is not beneficial to installation. (3) When the earthquake-resistant structure resists the earthquake action, the structure cannot freely stretch in the horizontal direction, and is not beneficial to earthquake resistance. (4) When the curtain wall needs to cross the floor, the traditional method is not easy to realize.
