Hydrophobic light prefabricated parapet wall flashing angle bead

The utility model discloses a hydrophobic light prefabricated parapet wall flashing angle bead which comprises an angle bead body, an extruded sheet arranged in the angle bead body and a clamp used for fixing the extruded sheet in the angle bead body. The extruded sheet, the clamp and the angle bead body are integrally formed in a pouring mode. According to the utility model, the light extruded sheet is arranged in the angle bead body, so that the overall weight meets the requirement under the condition that the thickness of the angle bead body is increased. When the thickness of the angle bead body is increased, the angle bead body has the advantages of being better in anti-seepage performance and higher in use and construction efficiency, and the problems that an existing prefabricated flashing component is thin, cracks are prone to occurring, waterproof coiled materials of a roof are difficult to press, accumulated water at the corner of a parapet leaks, wet operation is needed in the laying process, and i
