The utility model provides a concatenation structure of wall body, is including the blockwork, reinforced concrete wall of treating the concatenation and at outside and architectural surface of the screed -coat of the integrative construction in outside surface of two kinds of wall bodies, the outside surface equipartition tangible form of reinforced concrete wall, the big or small homogeneous phase sharp conical mao granule that draws together, external between the piece department on the outside of blockwork surface and the outside surface of reinforced concrete wall and the screed -coat have a crack control steel wire mesh sheet, and this crack control steel wire mesh sheet hangs and draws a mao granule in the one end cover of reinforced concrete wall. The utility model discloses the wall that is favorable to solving screed -coat and concrete wall forms even bond stress, and the restriction screed -coat is wet shrink futilely, when avoiding different kind wall bodies to splice, and concrete wall's wall hollowing fracture, and then avoid the wall secondary to repair, and reduce follow -up claim incident and take place, there are great quality income and social.
