A construction structure making for a breast wall is provided to construct a curved breast wall simply. A unit block forming a breast wall includes a front surface flat board(10), a rear surface flat board(20), a side surface flat board(30), and an insertion protrusion(50). The rear surface flat board is spaced apart from the front surface flat board. The rear surface flat board has the same height as that of the front surface flat board, and a width narrower than that of the front surface flat board. The side surface flat board has a first end portion coupled to the end portion of the front surface flat board and a second end portion coupled to the end portion of the rear surface flat board. A receiving groove is formed on the top surface of the side surface flat board. The side surface flat board has the same height as that of the front surface flat board. The insertion protrusion is inserted into the receiving groove. |
