Assembling type parapet wall and construction method thereof

The invention discloses an assembling type parapet wall and a construction method thereof. The assembling type parapet wall comprises an EPS shear wall module and a prefabricated type parapet wall coping. The prefabricated type parapet wall coping comprises a polystyrene board, high-strength concrete, constructional reinforcement and a tenon. The high-strength concrete is in a right-angled n shape. The polystyrene board is arranged on the inner side of the high-strength concrete. A nut is embedded on the high-strength concrete. Prefabricated type parapet wall coping components are combined through a mortise and tenon structure in a pluggable mode. The prefabricated type parapet wall coping is installed on the EPS shear wall module. The assembling type parapet wall has the advantages that the prefabricated type parapet wall coping is produced in a factory, top surface gradient and bottom face water drip are formed at a time, the parapet wall is combined by adopting the existing EPS shear wall module in the pluggable mode, a formwork is replaced, the reinforcement is bound inside, concrete is poured, the parapet wall can be directly installed on the coping after the top is leveled, and construction and installation are convenient.
