Definitions

  • the present invention relates to a curved surface-shaped ceiling structure and, more particularly, to a curved surface-shaped ceiling structure provided in a theater, wherein the ceiling structure is formed in a curved surface type shell shape covering the seats of a theater to expose a screen so that the ceiling structure can secure structural continuity with the screen having curvature in a horizontal axis and vertical axis.
  • a movie theater has a structure equipped with a rectangle screen within a building of a rectangular parallelepiped having the surface of a vertical wall, and is fabricated to have a structure that allows audiences to watch visual media within a specific space.
  • the rectangle screen has structural problems in that it prevents audiences from securing a sufficient angle of view in watching visual media and a sounding effect which may be felt by the body is greatly different depending on a seat due to the building of a rectangular parallelepiped. Accordingly, various methods are recently proposed in order to solve such problems.
  • a method for implementing the shape of a screen in a curved surface form is emerging as one of methods for solving the problems. More specifically, in the case of a current IMAX theater, a movie is screen using a curved screen having specific curvature in a horizontal axis.
  • a theater building itself or a structure itself has to be designed so that the curved screen can be installed on the building or structure by taking into consideration the curved surface of a curved screen from the time when a theater is designed. Accordingly, there is a problem in that the curved screen must be newly installed on the existing buildings of a rectangular parallelepiped form or the existing structures for viewing, which have been designed to be suitable for rectangle screens. Furthermore, there are problems in that luminosity of an image is reduced because it is difficult to project an image of constant luminosity on the surface of the curved screen and image content suitable for the curved screen must be separately produced.
  • the present invention has been invented based on such a technological background and also has been invented to satisfy the aforementioned technological needs and to provide additional technological elements that may not be easily invented by those skilled in the art to which the present invention pertains.
  • an object of the present invention is to provide a curved surface-shaped ceiling structure, which is capable of securing structural continuity with a screen having curvature in a horizontal axis and a vertical axis, enhancing a sense of immersion through a design unity and the homogeneity of a sound quality effect, and effectively controlling a howling phenomenon.
  • the ceiling structure in a ceiling structure provided in a theater, is formed in a curved surface type shell shape covering the seats of a theater so that a screen is exposed.
  • the ceiling structure may include a plurality of curved line members formed in a curved line form in a first direction and disposed in parallel in such a way as to be spaced apart from each other at a specific interval and a plurality of binding members spaced apart from each other at a specific interval and disposed in a second direction so that the plurality of curved line members is bound together.
  • the ceiling structure may further include a plurality of assistant members spaced apart from each other at a specific interval and disposed in a third direction so that the plurality of binding members is bound together.
  • finishing member may be combined with the binding members and/or the assistant members.
  • a plurality of perforations may be formed in the finishing member.
  • the plurality of curved line members may have the same shape.
  • an end on one side of the curved line member may be disposed to come into contact with a bottom.
  • the plurality of curved line members may be disposed to have height gradually lowered toward one side or both sides based on one curved line member.
  • both ends of the curved line member may be disposed to come into contact with the bottom.
  • the ceiling structure in a theater including a ceiling structure, may be formed in a curved surface type shell shape covering the seats of the theater so that a screen is exposed.
  • the ceiling structure may be fixed by hanger members provided in the upper structure of the theater.
  • the ceiling structure may include a plurality of curved line members formed in a curved line form in a first direction and disposed in parallel in such a way as to be spaced apart from each other at a specific interval and a plurality of binding members spaced apart from each other at a specific interval and disposed in a second direction so that the plurality of curved line members is bound together.
  • the curved line members may be fixed by hanger members.
  • the ceiling structure may further include a plurality of assistant members spaced apart from each other at a specific interval and disposed in a third direction so that the plurality of binding members is bound together.
  • a finishing member may be combined with the binding members and/or the assistant members.
  • a plurality of perforations may be formed in the finishing member.
  • the plurality of curved line members may have the same shape.
  • the plurality of curved line members may be disposed to have height gradually lowered toward one side or both sides based on one curved line member.
  • a ceiling structure construction method for constructing a ceiling structure in a theater may include the steps of (a) disposing a plurality of curved line members formed in a curved line form in a first direction in such a way as to be spaced apart from each other at a specific interval, (b) separating and disposing a plurality of binding members in a second direction at a specific interval so that the plurality of curved line members is bound together, and (c) combining a finishing member with binding members.
  • step (a) may include providing hanger members in the upper structure of the theater and fixing the curved line members to the hanger members.
  • the plurality of curved line members may have the same shape, and an end on one side of the curved line member may be disposed to come into contact with the bottom.
  • the plurality of curved line members may be disposed to have height gradually lowered toward one side or both sides based on one curved line member.
  • both ends of the curved line member may be disposed to come into contact with the bottom.
  • the step (b) may include separating and disposing a plurality of assistant members at a specific interval in a third direction so that the plurality of binding members is bound together.
  • the step (c) may include combining a finishing member with the binding members and/or the assistant members.
  • a plurality of perforations may be formed in the finishing member.
  • the curved surface-shaped ceiling structure can secure structural continuity with a screen having curvature in horizontal axis and the vertical axis because the ceiling structure is formed in a curved surface type shell shape covering the seats of a theater so that the screen is exposed.
  • the curved surface-shaped ceiling structure can be easily installed stably even without a separate change in the design of an existing building of a rectangular parallelepiped or structure for viewing.
  • an audience can have a sense of immersion and a high feeling of movement can be delivered to an audience because a design unity with a screen having curvature in the horizontal axis and the vertical axis is secured.
  • an auditory sense of immersion can be enhanced because the homogeneity of a sound quality effect can be sought through the curved surface-shaped ceiling structure.
  • a howling phenomenon can be effectively controlled because the finishing member is coupled and the plurality of perforations is formed in the finishing member.
