6. The construction method of the back wall formwork protection integrated plate according to claim 1, characterized by comprising the following steps: in S4, the number of the fixing members: not less than 12 per square meter.
7. The construction method of the back wall formwork protection integrated plate according to claim 1, characterized in that: in S6, the number of the alkali-resistant glass fiber mesh cloth is four, the alkali-resistant glass fiber mesh cloth is respectively arranged at four corners of the door and window opening, and the center parting line of the alkali-resistant glass fiber mesh cloth passes through the center point of the door and window opening.
8. The construction method of the back wall formwork protection integrated plate according to claim 1, characterized in that: in S6, at the decorative concave seam, the gridding cloth is embedded into the bottom layer polymer mortar along the groove, if the gridding cloth is broken at the decorative concave seam, the gridding cloth must be overlapped, and the overlapping width is not less than 65mm.
9. The construction method of the back wall formwork protection integrated plate according to claim 1, characterized by comprising the following steps: in S6, the two-way winding angles of the grid cloth embedded and pasted from the two connected walls are needed at the yin and yang corners of the walls and are mutually overlapped, and the overlapping width of each surface is not less than 200mm.
