The invention discloses a construction technology for processing a glass curtain wall into a hollow glass curtain wall. The construction technology comprises a main frame fixing the glass curtain wall and includes steps of 1) contiguously connecting spacing bars for assembling a support frame to inner edges of the main frame by sealant spread at corners of the spacing bars; 2) attaching the integral glass to the spacing-bar frame so as to form a cavity among the spacing-bar frame, the glass curtain wall and the glass; and 3) injecting sealant to fill space between the spacing-bar frame and the main frame and gaps between the glass and the main frame and reserving two air holes so that the cavity is a sealed cavity with two reserved air holes. After modification, heat transfer coefficient of the hollow glass curtain wall is one third of that of the glass curtain wall, heat transfer coefficient is greatly decreased, and ideal energy-saving effect can be achieved. Furthermore, modification is completed on the or
