The invention discloses a a nylon net rib concrete structured light large plate inner wall and preparation equipment thereof, a preparation method of the preparation equipment of the nylon net rib concrete structured light large plate inner wall, and a mounting method of the nylon net rib concrete structured light large plate inner wall. The nylon net rib concrete structured light large plate inner wall comprises double-layer nylon nets as inner and outer wall surfaces, filling slurry, and arc wave insulation layers laid between the inner and outer wall surfaces at intervals. The beneficial effects are as follows: the construction speed is accelerated; the construction period is shortened; the large-scale factory production can be achieved; the building load and the cost are reduced; the building use area is increased; the inner wall and the frame are integrated to improve the earthquake resistance, crack resistance, violence resistance and fire resistance; the production field requirement is low; the land use area is saved; and the enterprise transformation and upgrading, the employee benefit level improvement and the government finance incoming increment are facilitated.
