Plastering-free and concealed pipe grooving-free secondary structure wall and construction method thereof

The invention discloses a plastering-free and concealed pipe grooving-free secondary structure wall and a construction method thereof. The plastering-free and concealed pipe grooving-free secondary structure wall comprises a first steel component pre-buried in a floor, wherein a constructional column is welded to the upper portion of the first steel component; at least one side face of the constructional column is connected with a wall body formed by riveting a plurality of building blocks; mortar joints exist between the building blocks; a ring beam is arranged at the supporting joint of the wall body; the ring beam is welded to the contact position of the constructional column through a second steel component pre-buried in the end of the ring beam; and the top of the constructional column is fixedly connected with a structural beam. The common quality problem that secondary structure concrete is rough in quality is solved, the masonry quality of a filler wall is remarkably improved, and the plastering-free
