Connecting structure for photovoltaic glass curtain wall and photovoltaic glass

The invention discloses a connecting structure for a photovoltaic glass curtain wall a photovoltaic glass. The connecting structure is arranged at the splicing position of two pieces of photovoltaic glass, and fastener side frames loaded with the photovoltaic glass are fixed on a purline; a mounting groove is formed along the length direction of the purline; an arc-shaped stress surface is formed on the inner wall of the bottom of the mounting groove; a bar-shaped external member which is adaptively contacted with the arc-shaped stress surface is arranged in the internal space of the bottom of the mounting groove; and the bar-shaped external member is connected with a plate pressing part which is positioned outside the fastener side frames through a screw to firmly presses the edges of the fastener side frames on the edge of the purline. The bar-shaped external member which is connected with the screw is matched with the arc-shaped stress surface on the bottom of the mounting groove, and cannot rotate freely due to the limit of the mounting groove on the purline, and the bar-shaped external member and the purline are in surface contact at the arc-shaped stress surface, so sliding of the bar-shaped external member which is equivalent to a nut in the mounting groove is avoided, the screw can be conveniently screwed during assembly, and the construction quality is improved when the construction speed is improved.
