Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ceiling panel that also serves as a duct and is used to realize a ceiling structure that combines ceiling air conditioning equipment and wiring equipment for cables, which is applied to general buildings.

[0002]

[Prior art]

 The ceiling structure in which the air supply duct and outlet of the air conditioner are installed in the ceiling is roughly divided into the independent duct method and the ceiling chamber air supply method. The independent duct method is a structure in which an independent duct, which is separate from the ceiling panel, is installed in the space between the concrete slab and the ceiling panel (finishing material). The ceiling chamber air supply method is to use the entire ceiling space as an air supply chamber for an air conditioner.There is no independent air supply duct, and the entire ceiling space serves as a duct space, which is provided at an appropriate position on the ceiling panel surface. It is a structure that blows out conditioned air from the outlet into the room.

In any type of ceiling structure, wiring equipment such as a power cable and a communication cable is provided under the ceiling or under the floor separately from the air conditioning equipment.

A structure called a cellular duct is known as a floor wiring system for office automation. In this method, the groove on the deck plate on the lower surface of the slab is used as a wiring space, and a special cover is attached to the lower surface of the deck plate to form a groove space orthogonal to the groove on the deck plate. The matrix-shaped groove space formed in this way is used as a wiring space for wiring power cables and communication cables for office automation equipment.

Conventionally, the above-mentioned independent duct type or ceiling chamber air supply type air conditioning equipment has been completely independent of the ceiling wiring structure incorporating the cellular duct as described above.

[0006]

[Problems to be solved by the device]

 In the case of the above-mentioned independent duct type ceiling structure, not only is it difficult to pre-manufacture ducts that include complicated bends, but the work of attaching ducts to the bottom surface of the slab and connecting them to each other is a manual task that is site-specific, so that As a very large-scale and troublesome construction. In addition, the height of the duct installation space is large, and the ceiling height is low even if the floor height is the same, so the floor height must be set high to achieve the desired ceiling height. Furthermore, with the independent duct system, when repairing or performing maintenance with the air conditioning duct installed in the ceiling, the ceiling panel should be peeled off or an inspection port should be made in advance at a certain point, and a narrow ceiling should be opened from there. It was very inconvenient to work behind the scenes.

On the other hand, the ceiling chamber air supply system has a much simpler structure than the independent duct system, the ceiling height can be increased at the same floor height, and maintenance work is easy. However, since the entire ceiling basin serves as the air supply chamber, there are often unintended gaps, and there is the problem that air leaks from the gaps to the outside, causing heat loss. In addition, since the heat of the conditioned air is absorbed by the concrete slabs, beams, or walls, heat loss occurs here as well. Furthermore, the volume of the air supply chamber becomes unnecessarily large, and the rise time from the start of operation of the air conditioner to the time when cold air or warm air is spread throughout the room becomes longer.

Further, in any of the above-described ceiling air conditioning systems, a plurality of air outlets having small openings are appropriately scattered and arranged on a wide ceiling surface, which is a so-called local air outlet type. There is. For local air outlets, the layout of multiple air outlets on the entire ceiling is an important point in achieving an efficient and comfortable air conditioning environment. The proper layout of the air outlet is closely related to the way of partitioning the room and the arrangement of heat sources such as desks and office equipment.

Generally, the air outlet layout of the conventional ceiling air conditioning system is not designed according to the individual indoor usage form, but the air outlets are arranged at appropriate intervals as a standard layout. There is. Therefore, the air outlet layout is extremely inappropriate depending on the indoor usage, and there are some areas where the air conditioning effect is too effective and other areas where it is not effective. In particular, if the air outlet is local and the opening is small, the velocity of the air blown from the air outlet increases, and the inconvenience that the cold air directly hits the person during cooling tends to occur.

Further, conventionally, since the air conditioning equipment on the indoor ceiling and the wiring equipment for cables have been designed and constructed separately, the number of equipment parts as a whole is large and the construction is troublesome, resulting in a high cost. Was there.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to combine an air conditioning facility and a wiring facility so that the construction is low cost, the construction is easy, and the floor height is little affected. Due to the structure, efficient air conditioning without heat loss can be achieved, the entire room can be evenly air-conditioned with weak airflow, and a ceiling air conditioning system with easy layout changes such as partial increase or decrease in air volume The objective is to provide a ceiling panel that also serves as a duct to realize a ceiling structure that facilitates wiring of cables.

[0012]

[Means for Solving the Problems]

 The ceiling panel also serving as a duct according to the present invention comprises a bottom open duct made of a heat insulating material having a flat U-shaped cross section with an open bottom, and a breathable panel joined so as to close the open bottom of the duct. The wiring guide member is provided on the upper surface of the lower surface open type duct so as to project in an appropriate pattern.

[0013]

[Action]

 The duct ceiling panel is placed under the slab so that the breathable panel is substantially flush with other ceiling panels, and the hollow portions of the duct ceiling panels are connected to the air conditioner by appropriately connecting them. However, the air-conditioned air blown from the air conditioner to the hollow portion is blown into the room from the breathable panel. In other words, the breathable panel on the lower surface of the ceiling panel that also serves as the duct becomes the outlet surface of the ceiling air conditioning system. In addition, the wiring guide member is provided on the upper surface of the lower surface open type duct in the duct ceiling panel, and the power cable, the communication cable, or the cables of OA equipment are arranged in an orderly manner by using this guide member. be able to.

【Example】

 1 and 2 show a wide-area blow-out type ceiling air-conditioning system constructed using a duct-combined ceiling panel according to an embodiment of the present invention. In the figure, 1 is a concrete slab that constitutes the ceiling and floor, 2 is a pillar, and 3 is a beam.

A large number of hanging bolts 4 are vertically provided on the lower surface of the concrete slab 1, and a large number of C channels 5 are horizontally arranged by using the hanging bolts 4 and the beams 3. Further, the T bar 6 is fixed by welding or the like so as to be horizontally laid on the lower surface of the C channel 5. The T-bar 6 is arranged in an inverted T-shape, with its horizontal overhanging part facing down. A large number of T-bars 6 are arranged in parallel at predetermined intervals, and the horizontal projections at the lower ends of the T-bars 6 are all located in the same horizontal plane.

The air-permeable ceiling panel 7 and the duct-combined panel 8 are mounted using the T bar 6 as a support member. In this embodiment, the air-permeable ceiling panel 7 and the duct-cumulative ceiling panel 8 are alternately installed for each section of each T-bar 6 installed in a parallel pattern.

The breathable ceiling panel 7 is a porous metal panel material such as punched metal or expanded metal, a porous molded panel material made of plastic, or a panel in which these are combined with coarse cloth. It is an air-permeable Arai panel made of wood. The width of this ceiling panel 7 is almost equal to the installation interval of the T-bars 6, and this is inserted between the T-bars 6, and both sides thereof are installed on the horizontal projections of the T-bars 6. .

The duct-cum-ceiling panel 8 is formed by previously integrating a breathable panel 8a similar to the breathable ceiling panel 7 and a bottom open duct 8b having a flat structure with an open bottom. The lower surface open type duct 8b is a member formed in a U-shaped cross section by using a heat insulating material such as glass wool or foamed resin, and the breathable panel 8a is combined in advance so as to block the open lower surface. It is joined. Therefore, the duct-combined ceiling panel 8 is a flat hollow rectangular cylinder, and functions as a duct of the air conditioning system as described later. In addition, the lower surface of the duct is the breathable panel 8a, which serves as a surface for blowing air from the duct into the room.

The duct / ceiling panel 8 is also arranged in the space between the two T-bars 6, and is placed on the horizontal projecting portion of the T-bar 6. As is apparent from the figure, the breathable panel 8a of the ceiling panel 8 also serving as the duct is flush with the other breathable ceiling panels 7 and serves as a ceiling finishing material together with the panel 7. The air-permeable ceiling panel 7 and the duct-cum-ceiling panel 8 are divided into appropriate lengths in the longitudinal direction of the T-bars 6 and are connected to each other while being placed between the T-bars 6. The hollow portion of the duct / ceiling panel 8 serves as an air supply path for air conditioning as described below, but has a connection structure that does not cause air leakage from the joint portion of the duct / ceiling panel 8 that communicates with each other.

Although not shown, the main body of the air conditioner is installed outdoors, the duct space of the ceiling panel 8 also serving as a duct is connected to the air outlet of the air conditioner, and the air permeable ceiling panel 7 and The space above the ceiling from the slab 1 is connected to the air intake side of the air conditioner. That is, the conditioned air that is pressure-fed from the air conditioner is sent into the interior of the ceiling panel 8 that also serves as a duct, and the conditioned air is blown out into the room through the breathable panel 8a. In addition, the space above the ceiling between the breathable ceiling panel 7 and the slab 1 is used as an exhaust path (return air space), and the air in the room is sucked into the ceiling via the breathable ceiling panel 7 and is returned to the air conditioner.

As described above, the inner space of the ceiling panel 8 also serving as a duct serves as an air supply duct for the air conditioning system, and at the same time, the entire breathable panel 8a serves as a blowing surface for conditioned air. Further, the entire breathable ceiling panel 7 serves as a suction surface of the air conditioning system, and the space behind the ceiling serves as a return air space.

Further, as shown in FIG. 2, a large number of wiring guide members 9 are formed in an appropriate pattern on the upper surface of the lower surface open type duct 8b in the ceiling panel 8 also serving as the duct. The wiring guide member 9 of this embodiment has a semicircular plate shape, and each member 9 is provided so as to project perpendicularly to the upper surface of the duct 8b. The plurality of wiring guide members 9 are arranged so as to form a straight line along both side ends of the duct 8b, and are also arranged side by side on two parallel straight lines in the central portion of the upper surface of the duct.

In FIG. 2, reference numerals 10, 11, and 12 denote cables to be laid in the ceiling. For example, 10 is a power cable, 11 is a communication cable such as a telephone line, and 12 is a network for interconnecting office computers and personal computers. It is a cable. These cables 10, 11, 12 are placed and wired on the upper surface of the ceiling panel 8 that also serves as a duct (bottom open type duct 8b) in the space above the ceiling. At that time, the cables 10, 11, 12 are sorted and arranged in an orderly manner. At the same time, a wiring guide member 9 is provided to prevent the positions of these cables from being easily dislocated. In other words, the wiring guide member 9 provided on the upper surface of the duct 8b serves as a means for regulating the wiring positions of the cables 10, 11, and 12. By using this guide member 9, various cables 10, 11, It is possible to classify the 12 by type and wire them in an orderly manner.

In the case where the ceiling panel 8 also serving as the duct is arranged in the direction orthogonal to the beam 3, if there is a space for passing cables between the lower surface of the beam 3 and the upper surface of the ceiling panel 8 also serving as the duct. No problem. However, when arranging the ceiling panel 8 that also serves as a duct so as to be almost in close contact with the lower surface of the beam 3, at the intersection between the beam 3 and the ceiling panel 8 that also serves as a duct, the cables are laid out as shown in FIG. 3 or 4. There is a need.

In the example of FIG. 3, holes 13 for passing cables are formed in the lower surface of the beam 3, and the cables 10, 11, 12 wired on the upper surface of the duct / ceiling panel 8 are passed through the holes 13. Wiring.

In FIG. 4, the cables 10, 11, 12 laid on the upper surface of the ceiling panel 8 also serving as the duct are diverted to the side surface side at the intersection with the beam 3.

[Effect of device]

 As described in detail above, the duct / ceiling panel of the present invention has a flat hollow cylindrical structure in which the lower surface is made of a breathable panel that also serves as a finishing material, and the upper surface and both side surfaces are made of heat insulating material. Yes, the ceiling panel that also serves as the duct and another ceiling panel are placed on a horizontal member that is provided under the slab so that the general ceiling panel surface and the breathable panel of the ceiling panel that also serves as the duct are flush with each other. It has a different structure. By connecting the hollow parts of the duct / ambient panel to each other and connecting them to the air conditioner, the duct / ambient panel functions as an air supply duct and a blowing surface of the air conditioner.

Therefore, the ceiling finish surface is lower than the lower surface of the beam by the thickness dimension of the duct / ceiling ceiling panel, which is flat, and the ceiling height is the same as that of the conventional independent duct type ceiling structure. It can be raised, and if the ceiling height is the same, the floor height can be lowered. In addition, the ceiling finishing material and the air-conditioning duct are integrated together, making the structure and construction much easier than the independent duct method, and a simple structure similar to the ceiling chamber air supply method. In addition, by arranging the ceiling panel that also serves as a duct, a large area of the ceiling surface can be used as a blowing surface, and air that is not too strong can evenly and satisfactorily air-condition the entire room.

Furthermore, since the wiring guide member is provided on the upper surface of the ceiling panel that also serves as the duct, power cables, communication cables, and cables for OA equipment are provided on the upper surface of the ceiling panel that also serves as the duct by using the guide member. The cables can be routed in an orderly manner. In this way, the ceiling finishing material and the ceiling air-conditioning equipment are integrated together, and the wiring equipment for cables in the ceiling is also integrated, resulting in a significant reduction in the number of parts as a whole. Facility construction is also very easy.
