The application discloses a construction method for improving the strength of fiber reinforced cement boards and relates to the field of building construction; the construction method for improving the strength of fiber reinforced cement boards effectively solves the problems of easy loosening, edge warping and deformation of the board under the traditional single-board fixing mode, significantly improves the overall connectivity of the board and the keel and the anti-deformation capacity of the wall, and forms a double-board cooperative stress structure by connecting long U-shaped steel to the inner side of the fiber reinforced cement board joint and by jointly restraining the edges of the adjacent boards on the keel; meanwhile, the water-resistant flexible putty is filled and pressed into the glass fiber mesh belt at the joint of the outer board, which not only can offset the joint stress of the fiber reinforced cement board caused by dry shrinkage, wet expansion and temperature change, prevent the putty layer from cracking and rainwater leakage, but also avoids forming a rigid filling layer to hinder the normal pressure relief of the wall.
