<p>A rain-proof external wall panel and a construction method of a rain-proof external wall. A panel body of the rain-proof external wall panel has a protrusion (b) on one side and a groove (a) matching with the protrusion (b) on the other side. The protrusion (b) is provided with multiple first recess portions (c) and second recess portions (d) in a staggered manner in a vertical direction. The first recess portion (c) and the second recess portion (d) are both recessed on the outer surface of the panel body, and top surfaces of the first recess portion (c) and the second recess portion (d) are inclined surfaces or staircase structures. A side surface of the groove (a) has a first cover plate (f) and a second cover plate (g). The first recess portion (c) and the second recess portion (d) are both provided with multiple first water guide grooves (4). The rain-proof external wall has multiple rain-proof external wall panels, and the construction method thereof comprises the following steps: i) prefabricating rain-proof external wall panels and conveying the rain-proof external wall panels to a construction site; ii) mounting a peg board (18-2) used for leveling and positioning on a roof beam; iii) hanging a prefabricated rain-proof external wall panel having a mounting insertion piece (18-1) on the peg board (18-2), and horizontally pushing the rain-proof external wall panel to the right position; iv) sealing a mounting gap through grouting. The rain-proof external wall panel automatically guides water for discharging, and plays a water-proof role. The construction method of the rain-proof external wall is simple and has a short construction period.</p> |
