Keel-free assembly type design structure of arc-shaped metal plate

The utility model discloses a keel-free assembly type design structure of an arc-shaped metal plate, which belongs to the technical field of building decoration and comprises a plurality of arc-shaped plates, a plurality of limiting rods and a plurality of limiting pieces, the limiting rods are connected to a wall top base layer and are clamped into the arc-shaped plates from one sides of the arc-shaped plates, and the limiting pieces are arranged on the arc-shaped plates. Each arc-shaped plate corresponds to at least three limiting rods, each limiting rod is connected with two limiting pieces, and the two limiting pieces clamp the edge of the arc-shaped plate. The plurality of limiting rods are connected to the wall top base layer and located at the edge of the arc-shaped plate, the arc-shaped plate can be fixedly installed only by connecting two limiting pieces to the limiting rods and firmly clamping the edge of the arc-shaped plate through the two limiting pieces, the installation structure is greatly sim
