Glass curtain wall system

A glass curtain wall system comprises a supporting frame, and the supporting frame is a mesh body formed by connecting a plurality of vertical rods and a plurality of cross rods into a whole. The glass curtain wall system is characterized in that a plurality of supporting rods are arranged, and the supporting rods are arranged on the cross rods or the vertical rods respectively; a plurality of keels are arranged, the two ends of each keel are connected with two corresponding supporting rods respectively, the keels are arranged to be in a mesh shape with a plurality of mesh holes, and each mesh hole is defined by a set of keels; each mesh hole is sealed by one piece of glass, and at least two edges of each piece of glass are arranged on the keels through base frames, rotatable frames, structural glue, supporting hooks, pressing plates and screws; the mesh holes are in an equilateral triangle shape, and the glass is in an equilateral triangle shape so as to be matched with the shape of the mesh holes. The glass curtain wall system has the advantages that the appearance effect is good, and the appearance does not have many points; the triangular glass of a large size can be mounted, and therefore productivity is improved; no hole needs to be formed in the glass, the strength of the glass cannot be lowered, and the workload of forming holes in the glass is reduced.
