Theater type building seat ventilation hole cambered arrangement hollow inclined plate and construction method thereof

The invention discloses a theater type building seat ventilation hole cambered arrangement hollow inclined plate and a construction method thereof. Ventilation hole bushings of the hollow inclined plate are arranged at intervals layer by layer in a cambered manner along the seat arrangement direction; filling blocks are arranged in a space formed by an upper layer steel bar mesh, a lower layer steel bar mesh and a ribbed beam steel bar framework; casting vibration holes are retained in the middle of the filling blocks; a tube slot matched with the cambered interface of each ventilation hole bushing is formed in one side face of each filling block; the upper ends and the lower ends of the ventilation hole bushings avoid main ribs of the lower layer steel bar mesh and the upper layer steel bar mesh and penetrate through the upper layer steel bar mesh; and upper openings of the ventilation hole bushings are temporarily closed. According to the theater type building seat ventilation hole cambered arrangement hollow inclined plate, the filling blocks are fixed by ribbed beams between the filling blocks; and floating of the filling blocks are controlled by a ribbed beam steel bar framework and a template supporting frame, so that the construction efficiency is effectively improved, and the forming quality is guaranteed. The theater type building seat ventilation hole cambered arrangement hollow inclined plate is suitable for various large-span prestress hollow cast-in-place inclined plate structure in which theater type building seat stages are in cambered arrangement, and positive pressure air feeding holes are required to be retained below a seat.
