The invention discloses a suspension type glass curtain wall. The suspension type glass curtain wall comprises L-shaped fixing bases, steel wire ropes, reinforcing steel bars, suspension devices and curtain wall plates, wherein the vertically corresponding L-shaped fixing bases are arrayed on each layer of concrete beams of a building at intervals, and the outer side of a vertical side plate of each L-shaped fixing base is vertically provided with a fixing lug; a steel wire rope is fixedly arranged between every two vertically corresponding fixing lugs; the suspension devices are arrayed on each steel wire rope at intervals, and each suspension device is composed of a connecting piece and a suspension piece with the cross in a T shape; each suspension piece is composed of an inserting plate vertically and movably inserted inside a corresponding clamp groove and a supporting plate horizontally fixed onto the inserting plate above a baffle; one of the curtain wall plates is arranged among four adjacent supporting plates. The suspension type glass curtain wall has the advantages that no transverse frame exists, the material is saved, the production cost is reduced, and the transparent feeling of the glass curtain wall is strengthened; the component is less, the installation technology is simple, the installation efficiency is high, and the labor cost is reduced; the installation of the glass curtain wall can be completed only indoors, workers do not need to work high above the ground outside, and the hidden danger is avoided.
