Description
TECHNICAL FIELD
[0001] 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.
BACKGROUND ART
[0002] In general, 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.
[0003] In this case, 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.
[0004] 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.
[0005] If such a curved screen is to be used, however, 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.
[0006] Furthermore, there are problems in that a sense of immersion
of an audience is reduced and a sound effect does not revive a
sense of immersion of the curved screen because the curved screen
and the ceiling structure do not secure continuity in structure and
are not united in terms of the design.
[0007] 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.

[0013] In this case, a plurality of perforations may be formed in
the finishing member.
[0014] Furthermore, the plurality of curved line members may have
the same shape.
[0015] In this case, an end on one side of the curved line member
may be disposed to come into contact with a bottom.
[0016] Furthermore, 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.
[0017] In this case, both ends of the curved line member may be
disposed to come into contact with the bottom.
[0018] According to an embodiment of the present invention, in a
theater including a ceiling structure, the ceiling structure may be
formed in a curved surface type shell shape covering the seats of
the theater so that a screen is exposed.
[0019] Furthermore, the ceiling structure may be fixed by hanger
members provided in the upper structure of the theater.

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.
[0021] Furthermore, 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.
[0022] In this case, a finishing member may be combined with the
binding members and/or the assistant members.
[0023] Furthermore, a plurality of perforations may be formed in
the finishing member.
[0024] Furthermore, the plurality of curved line members may have
the same shape.
[0025] Furthermore, the plurality of curved line members may be
disposed to have height gradually lowered toward one side or both

the finishing member.
Advantageous Effects
[0034] In accordance with the present invention, the curved
surface-shaped ceiling structure can secure structural continuity

[0035] Furthermore, 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.
[0036] Furthermore, 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.
[0037] Furthermore, 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.
[0038] Furthermore, a howling phenomenon can be effectively

MODE FOR INVENTION
[0044] The details of the objects and technological configurations
of the present invention and acting effects thereof will be more
clearly understood from the following detailed description based on
the accompanying drawings. Hereinafter, embodiments of the present
invention are described in detail with reference to the
accompanying drawings.
[0045] Embodiments disclosed in this specification should not be
interpreted as limiting or used to limit the range of right of the
present invention. It is evident to those skilled in the art that a
description including the embodiments of this specification has
various applications. Accordingly, unless otherwise defined by the
claims, some embodiments described are illustrative for better
understanding, and the range of right of the present invention is
not intended to be restricted by the embodiments.
[0046] Function blocks illustrated in the drawings and described
hereunder are only examples of possible implementations. In other
implementations, different functional blocks may be used without
departing from the spirit and scope of the detailed
description.
[0047] Furthermore, it should be understood that an expression that
some elements are included is an expression of an open type and the
expression simply denotes that the corresponding elements are
present, but does not exclude additional elements.
[0048] Furthermore, when it is said that one element is connected
or coupled to the other element, it should be understood that one
element may be directly connected or coupled to the other element,
but a third element may exist between the two elements.
Furthermore, expressions, such as "the first" and "the second", are
expressions used to only distinguish a plurality of elements from
one another, and do not limit the sequence of the elements or other
characteristics.
[0049] FIGS. 1 to 6 are diagrams showing a curved surface-shaped
ceiling structure according to various embodiments of the present
invention.
[0050] As shown in FIGS. 1 to 4, according to the present
invention, in the ceiling structure provided in a theater, the
ceiling structure CS is formed in a curved surface type shell shape
covering the seats ST of a theater T so that a screen S is
exposed.
[0051] In this case, the screen S is a curved screen and may
include a plurality of long-axis members and a plurality of
short-axis members. More specifically, the screen S includes the
pair of long-axis members formed in a specific direction and spaced
apart from each other at a specific interval and the pair of
short-axis members formed in another specific direction and spaced
apart from each other at a specific interval. The long-axis members
and the short-axis members have curvature of a specific size, and
the pair of long-axis members and the pair of short-axis members
are joined together to have four corners.
[0052] That is, the ceiling structure CS is formed in a curved
surface type shell shape and can secure structural continuity with
the screen including the long-axis members and short-axis members
having curvature of a specific size.
[0053] More specifically, if the curved screen S is to be installed
on an existing building of a rectangular parallelepiped or an
existing structure for viewing, a sense of immersion is visually
reduced and there is a limit to the transfer of the feeling of
movement because the building or structure for viewing and the
curved screen S are separated in structure.
[0054] In contrast, the ceiling structure CS has a curved surface
type shell shape and thus can secure the structural continuity of a
curved line with the curved screen S. Furthermore, the curved
screen S and the curved surface-shaped ceiling structure CS can be
stably installed easily even without a separate change in the
design.
[0055] Accordingly, the curved surface-shaped ceiling structure CS
of the present invention enables an audience to have a sense of
immersion and can transfer a high feeling of movement to an
audience because it secures a design unity with the curved
screen.
[0056] Furthermore, 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.
[0057] Meanwhile, as shown in FIGS. 1 to 4, the ceiling structure
CS may include a plurality of curved line members 100 formed in a
curved line form in a first direction, spaced apart from each other
at a specific interval and disposed in parallel and a plurality of
binding members 200 spaced apart from each other at a specific
interval in a second direction so that the plurality of curved line
members is bound together.
[0058] As shown in FIGS. 1 to 4, the curved line members 100 of the
ceiling structure CS may be continuously disposed to be vertical to
a normal direction to the center of the screen and may be
continuously disposed in parallel in the normal direction.
[0059] As shown in FIGS. 1 and 2, if the curved line members 100
are disposed continuously in parallel in a direction vertical to a
normal direction to the center of the screen S, the screen S needs
to be exposed. Accordingly, it is preferred that the curved line
member 100 is fabricated to have continuous curvature so that a
sense of alienation is not generated between an end on the screen
side of the curved line member 100 and curvature of the screen
S.
[0060] Furthermore, as shown in FIGS. 3 and 4, if the curved line
members 100 are disposed continuously in parallel in a normal
direction to the center of the screen, it is preferred that the
curved line members 100 provided on the screen side and the screen
S can secure structural continuity by controlling the angle of the
curved line members 100 or providing an additional finishing
material.
[0061] In this case, the ceiling structure CS may include an end
member 500 having a shape corresponding top curvature of the screen
S, as shown in FIGS. 1 and 2.
[0062] One binding member 200 may be continuously bound to three or
more curved line members 100. In this case, the binding member 200
may be formed of a curved line-shaped member.
[0063] Furthermore, both ends of one binding member 200 may be
bound to a pair of the curved line members 100. In this case, the
binding member 200 may be formed of a straight line-shaped member
having a relatively short length.
[0064] In this case, the first and the second directions are not
limited to the normal direction to the center of the screen and the
vertical direction thereto, and the first and the second directions
do not need to be vertically bound together.
[0065] Meanwhile, the "binding" defined in the present invention
means that independent members remain in contact with each other,
and covers meanings, such as attachment, adhesion, coupling,
welding, and holding.
[0066] Furthermore, the ceiling structure CS may include a
plurality of assistant members 300 spaced apart from each other at
a specific interval in a third direction so that the plurality of
binding members 200 is bound together.
[0067] It is preferred that both ends of one assistant member 300
are bound between a pair of the binding members 200. In this case,
the assistant member 300 may be formed of a straight line-shaped
member having a relatively short length.
[0068] One assistant member 300 may be continuously bound to three
or more binding members 200. In this case, the assistant member 300
may be formed of a curved line-shaped member.
[0069] In this case, the third direction may be a direction
parallel to the first direction, that is, the direction in which
the curved line members 100 are disposed.
[0070] Meanwhile, a finishing member 400 may be coupled to the
binding members 200 and/or the assistant members 300.
[0071] The finishing member 400 means a panel covering the ceiling
structure, and may be divided into a primary curved surface
finishing member having curvature with respect to only a
one-direction cross section and a secondary curved surface
finishing member having curvature with respect to only a
bi-directional cross section.
[0072] Furthermore, the ceiling structure may have different
curvature depending on its position. The size of the finishing
member may be different. For example, the ceiling structure may be
completed using a simple plane type member not having curvature by
disposing the binding members 200 or the assistant members 300 at
points having small curvature at a wide interval and disposing the
binding members 200 or the assistant members 300 at points having
great curvature at a narrow interval.
[0073] In this case, if the finishing member 400 is fabricated to
have the secondary curved surface, a manufacturing cost is
increased, and there is a difficulty in construction because only a
specific finishing member designed suitably for a specific location
has to be selectively coupled.
[0074] Accordingly, as shown in FIGS. 5 and 6, the curved
surface-shaped ceiling structure CS of the present invention can
form a net type frame structure by binding the curved line members
100 and the binding members 200 and additionally binding the
assistant members 300 at the same time. Furthermore, the finishing
member 400 can be combined with the curved surface-shaped ceiling
structure CS so that it comes into contact with the binding members
200 and/or the assistant members 300.
[0075] In this case, economy and the construction ability can be
secured at the same time because the primary curved surface
finishing member can be used as the finishing member 400.
[0076] Furthermore, the finishing member 400 can be directly
combined with the binding members 200 without using a separate
assistant member 300 because the distance between the binding
members 200 forming the ceiling structure CS can be short depending
on the size of a theater.
[0077] Meanwhile, the curved surface-shaped ceiling structure CS of
the present invention may be provided in the theater of a building
of a rectangular parallelepiped having the surface of a vertical
wall.
[0078] In this case, there is a problem in that a howling
phenomenon is generated. More specifically, a phenomenon in which
an isolated space is formed between the curved surface-shaped
ceiling structure CS and the theater T and a sound output by a
sound device is refracted and reflected within the isolated space,
inputted to the sound device again, amplified and output is
generated.
[0079] Accordingly, the finishing member 400 may include a
plurality of perforations 401. The perforations 401 functions to
offset a sound refracted and reflected by the isolated space
between the ceiling structure CS and the theater T.
[0080] In this case, it is preferred that the finishing member 400
secures fireproof performance within a theater by attaching
fireproof sheet paper to the finishing member 400. In this case,
various aesthetic factors, such as a wood pattern, may be added to
the fireproof sheet paper in order to secure a sense of aesthetic
appreciation.
[0081] Meanwhile, as shown in FIGS. 1 and 2, the plurality of
curved line members 100 may have the same shape. If the curved line
members 100 having the same shape are disposed in parallel, a shell
structure of a tunnel shape having a curved line with respect to
only a one-direction cross section is formed.
[0082] In this case, it is economic because the surface of the
vertical wall of the theater T is exposed and an entrance and exit
and the stairs of the theater can be used without any change.
Furthermore, there is an advantage in that the construction ability
is improved because the primary curved surface finishing member has
only to be used to combine the finishing member 400.
[0083] In this case, structural stability can be secured because an
end on one side of the curved line member 100 can be disposed to
come into contact with the bottom. In this case, an opening portion
600 is formed by removing portions of the binding members 200
coming into contact with the bottom, and a projector or an entrance
and exit may be formed in the opening portion 600 in order to
secure functionality.
[0084] In this case, it is preferred that a metal reinforcement
structure frame is additionally installed to dispose the projector
in the opening portion 600.
[0085] Furthermore, as shown in FIGS. 3 and 4, the plurality of
curved line members 100 may be disposed to have height gradually
lowered toward one side or both sides based on one curved line
member.
[0086] Accordingly, a dome-shaped shell structure having a curved
line with respect to the bi-directional cross section is formed. In
this case, only the screen S of the theater T is exposed, but the
surface of a vertical wall is not exposed, and thus an opening
portion, such as a separate entrance and exit, has to be formed. In
this case, a construction cost is slightly increased, but
independency from the theater can be maintained. Accordingly, there
are advantages in that structural continuity with the screen can be
secured and a sense of immersion can be enhanced visually and
aurally.
[0087] In this case, since both ends of the curved line member can
be disposed to come into contact with the bottom, hanger members
700 to be described later are simplified, the construction ability
can be secured, and structural stability can be easily sought.
[0088] In general, an existing theater has been constructed in form
in which a screen is mounted on a building of a rectangular
parallelepiped or a structure for viewing. In contrast, according
to the present invention, as shown in FIG. 3, in the theater T
equipped with the curved surface-shaped ceiling structure, the
ceiling structure CS is formed in a curved surface type shell shape
covering the seats ST of the theater T so that the screen S is
exposed.
[0089] Accordingly, the curved surface-shaped ceiling structure CS
can be disposed easily and stably within the theater even without a
separate change in the design.
[0090] The ceiling structure CS may be fixed by beams, that is, the
upper structures of the theater T, or the hanger members 700
provided in a gutter. The hanger members 700 may be combined with
the curved line members 100 or the binding members 200 and fixed
thereto.
[0091] The hanger member 700 may include a spacer 710 coupled to
the curved line member 100 or the binding member 200 orthogonally
and a hanger pipe 720 coupled to the spacer 710 in a vertical
direction. In this case, a hollow type metallic pipe may be
preferably used as the spacer 710 and the hanger pipe 720. The
spacer 710 and the hanger pipe 720 may be coupled using various
known methods, such as welding or bolting.
[0092] In this case, the hanger pipes 720 may be disposed at
intervals of 1,200 mm using angular pipes of 1.4T mm in 50.times.50
standard. A shaded bracing may be provided on both sides of the
hanger pipe 720 in order to secure structural supplement so that
the hanger pipe 720 is not fluctuated by vibration or a load. In
this case, an angular pipe of 1.4T mm in 30.times.30 standard may
be used as the bracing.
[0093] Furthermore, a theater equipped with the curved
surface-shaped ceiling structure of the present invention may
include all of the characteristics of the curved surface-shaped
ceiling structure, and a redundant description thereof is
omitted.
[0094] Meanwhile, as shown in FIG. 7, a ceiling structure
construction method for constructing a ceiling structure in a
theater according to the present invention includes the steps of
(a) disposing the plurality of curved line members 100 formed in a
curved line form in the first direction in such a way as to be
spaced apart from each other at a specific interval, (b) separating
and disposing the plurality of binding members 200 in the second
direction at a specific interval so that the plurality of curved
line members 100 is bound together, and (c) combining the finishing
member 400 with the binding members 200.
[0095] In this case, at step (a), it is preferred that the curved
line members 100 are disposed by lifting and need to be fixed in
the state in which the degree of horizontality and the degree of
verticality have been set.
[0096] Furthermore, at step (a), the hanger members 700 are
provided in the upper structure of the theater T, and the curved
line members 100 may be fixed to the hanger members 700. As
described above, the curved line members 100 may be coupled to the
binding members 200.
[0097] Meanwhile, according to an embodiment, at step (a), the
plurality of curved line members 100 has the same shape, and an end
on one side of the curved line member 100 may be disposed to come
into contact with the bottom. In this case, it is preferred that
the curved line member 100 is coupled to the bottom through anchor
bolts. Structural stability can be secured by additionally coupling
the hanger members 700.
[0098] Furthermore, according to another embodiment, at the step
(a), the plurality of curved line members 100 may be disposed to
have height gradually lowered toward one side or both sides based
on one curved line member 100.
[0099] In this case, it is preferred that the height and distance
of an adjacent curved line member 100 are designed by taking into
consideration curvature of the ceiling structure CS. The curved
line member 100 may be disposed to have both ends come into contact
with the bottom.
[0100] Meanwhile, at step (b), the plurality of assistant members
300 may be disposed in the third direction in such a way as to be
spaced apart from each other at a specific interval so that the
plurality of binding members 200 is bound together. In this case,
at step (c), the finishing member 400 may be combined with the
binding members 200 and/or the assistant members 300.
[0101] Furthermore, the plurality of perforations 401 may be formed
in the finishing member 400. The perforations 401 can function to
offset a sound refracted and reflected by an isolated space between
the ceiling structure CS and the theater T, thus being capable of
effectively removing a howling phenomenon.
[0102] As described above, those skilled in the art to which the
present invention pertains will understand that the present
invention may be implemented in other detailed forms without
changing the technological spirit or essential characteristics of
the present invention. Accordingly, the aforementioned embodiments
should not be construed as being limitative, but should be
construed as being only illustrative from all aspects. The range of
right of the present invention is disclosed in the appended claims
rather than the detailed description, and it should be understood
that all modifications or variations derived from the meanings and
scope of the present invention and equivalents thereof are included
in the scope of the appended claims.
