Roof tenon-and-mortise structure ventilation clerestory

The utility model relates to a roof tenon-and-mortise structure ventilation clerestory which comprises frameworks and connecting rods, the frameworks are connected through the connecting rods, and the connecting rods are connected with the frameworks in a tenon-and-mortise mode. The framework comprises transverse rods, vertical rods, an outer arc framework and a triangular roof fixing frame, the outer arc framework is of an inverted U-shaped structure, the tops of the two sides of the outer arc framework are in arc transition, the bottoms of the two sides of the outer arc framework incline inwards, the triangular roof fixing frame is of an inverted V-shaped structure, and the triangular roof fixing frame is arranged on the inner side of the outer arc framework. The two ends of the triangular roof fixing frame are connected with the two sides of the outer arc framework respectively, the vertical rods which are in bilateral symmetry are connected to the lower portion of the triangular roof fixing frame, the tra
