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

Abstract

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.

Description

technical field [0001] The invention relates to a construction method for the floor slab of an audience hall of a theater building. Background technique [0002] With the continuous vigorous development of my country's economy in recent years, the average income of the whole society has gradually increased, and the cultural life needs of the people have gradually increased. Cinemas, conference halls, TV audience halls, etc., the indoor spaces of these buildings generally have the following functions: the steps of the seats are arranged in an arc, and the steps rise step by step. There are positive pressure air supply holes, and these functional halls are generally realized by using cast-in-place solid slabs or steel structures. [0003] In existing theater buildings, the auditorium and the rehearsal hall below the auditorium require a large space, and the structural frame columns cannot extend to the ground floor of the auditorium. A large number of seat ventilation holes ar...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a hollow slant plate with arc-shaped arrangement of ventilation holes in a theater-like building seat and a construction method thereof. It is necessary to solve the difficulty in positioning the ventilation holes in the construction of the existing seat ventilation holes in the arc-shaped arrangement of hollow slant plates and on the filling block. The technical problem of accurately leaving holes; and solving the technical problems that the ventilation hole casing is easy to move when the concrete is poured, the hollow slab is difficult to fix, easy to float, and the hollow slab ribs are difficult to arrange
