Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a ceiling structure in which ventilation and ventilation are provided between the ceiling and the room for ventilation.

[Prior art and its problems]

Conventionally, air conditioning performed in buildings, offices, etc. is performed by providing an air conditioner or an air conditioning duct in the ceiling so that the entire room is uniform, and then blowing air into the ventilation holes on the ceiling surface to perform air conditioning. However, because duct installation is difficult in a narrow space above the ceiling and duct construction becomes complicated, in recent years, the entire above-ceiling space is considered as a wide duct body and conditioned air is sent into the above-ceiling space. Has been adopted to ventilate the room by communicating.

As a ceiling for performing the air conditioning, as shown in FIG. 5, a mounting bracket (B) such as a T-shaped bar for supporting the ceiling plate (A) is arranged at predetermined intervals, and a hanging tool (C) is provided. ), Air was blown out and air was taken in from the central opening (D) of the mounting bracket (B), but the opening (D) of the air passage formed from the bottom of the room to the ceiling surface. However, there is a problem in that the appearance is spoiled and the appearance is impaired, and the air blows directly downward so that it directly hits the skin of the person directly underneath, which causes discomfort.

Further, when a partition wall used for partitioning the office is erected, if the upper end of the partition wall and the air outlet coincide with each other, the outlet is blocked and sufficient air conditioning cannot be achieved.

[Purpose of device]

The present invention has been made in view of such problems, and the finish of the ceiling surface is beautiful, and the air does not hit a person directly passing therebelow, and the air conditioning is not hindered even by the arrangement of partitions or the like. It provides the structure.

[Means for solving problems]

In order to achieve the above-mentioned object, the ceiling structure of the present invention is as shown in the drawings corresponding to the embodiments; Is formed integrally with the side wall surface (2a) of the stepped portion (2a) and has a plurality of through holes.
The ceiling plate placement bar (1) having the holes (3) is arranged in parallel or in a grid pattern so as to provide a space behind the ceiling.

In addition, the ceiling board (8) is placed on the step (2) of the ceiling board placing bar (1).
A peripheral surface of the mounting bar (1) is placed on a ceiling surface to form a ceiling surface.
The structure communicated via (3).

; Is adopted as the technical means.

[Action]

The through hole (3) of the air outlet is the step of the ceiling plate placement bar (1).
Since the side wall surface (2a) of (2) is drilled, it becomes a ceiling surface that is hard to see from the bottom of the room and has a beautiful appearance, and the air sent from the air conditioner is directed horizontally from the through hole (3). The air blown out to the room is diffused along the ceiling surface, so that the blown air spreads throughout the room, and uniform air conditioning can be performed.

Further, even when the partition panel is installed upright, the through hole (3) of the air outlet is not blocked by the upper end portion of the panel (12), and air conditioning is not hindered.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Is a ceiling plate mounting bar with a substantially inverted hat cross-section that is made of a long mold formed by extruding aluminum or bending stainless steel, and crosses it at predetermined intervals only in the vertical direction or only in the horizontal direction or vertically and horizontally. They are arranged in a grid pattern or the like.
This ceiling-mounting bar (1) has an upper surface opened and a lower surface finished to a decorative surface, and stepped portions (2) horizontally protruding outward on both side surfaces of the lower end portion in the longitudinal direction. It is formed so as to integrally project over the entire length, and is provided with a space portion of an appropriate size provided on the back of the ceiling. Side wall surface (2a) of this step (2)
A plurality of through holes (3) are formed at predetermined intervals in the longitudinal direction of the step (2). (4) is a vertical wall surface on both sides of the mounting bar (1), the upper end of which is turned inward to form an engaging portion (5).
Reference numeral (6) is a suspending tool which suspends the mounting bar (1) by engaging with the engaging portion (5), and is attached to the ceiling base by wires (7), bolts and the like. The above-mentioned placement bar does not necessarily have to be provided by a suspending means, and may be provided so as to be horizontally mounted on the upper end portion of a wall body such as a partition wall. (8) is a ceiling plate made of rock wool or the like, and a notched stepped portion (9) is formed in a stepped shape so as to be mounted on the stepped portion (2) of the placing bar (1) on one side surface side and the back surface side.
(9) is engraved. This notch step (9) is formed wider than the protruding length of the step (2) of the placing bar (1),
Between the side wall surface (9a) of the stepped portion (9) of the ceiling plate (8) and the side wall surface (2a) of the step portion of the mounting bar (1) when placed on the step portion (2) of (1). A gap is created and air is blown out from this gap. The depth side wall surface (9a) of the notch step (9) may be a vertical surface with respect to the lower side or an inclined surface, but the air blowing through hole (2) is less noticeable on the vertical surface. .

FIG. 3 shows another embodiment of the present invention, in which a partition panel for the room is erected just below the ceiling board mounting bar (1) to partition the room.

That is, the upper rail (11) is integrally attached to the central portion of the lower surface of the ceiling plate placing bar (1) having the same structure as described above by a connecting tool (10) such as a bolt, and the partition panel (12) is attached to the rail (11). ) Are fitted together, and the air blow-through hole (3) formed in the side wall surface (2a) of the stepped portion (2) of the ceiling plate mounting bar (1) can be installed even when the panel (12) is erected. It will not be blocked and air conditioning will not be disturbed.

In addition, in the above-mentioned two embodiments, the notch step portion (9) is engraved on two sides of the ceiling plate (8) and the step portion of the ceiling plate mounting bar (1) is provided.
(2) It has been explained that the lower surface of the placing bar (1) and the lower surface of the ceiling plate (8) are flush with each other when placed on, but the invention is not limited to this, and for example, as shown in FIG. As shown, place the ceiling plate (8 ') without the notch step on the step part (2) of the placing bar (1) so that the step part (2) is located below the ceiling plate (8'). May be.

Furthermore, if a part of the lower surface of the ceiling board mounting bar (1) is made of a translucent synthetic resin film, it can be used for ceiling lighting by housing the lighting fixture in the space between the vertical cross sections on both sides. It is possible.

[Effect of device]
