[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 method, 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, 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. With the structure, it is possible to realize efficient air conditioning without heat loss, and to realize a ceiling air conditioning system whose layout can be easily changed such as partial increase / decrease in air volume, and a ceiling structure with easy wiring of cables. The purpose is to provide a ceiling panel that also serves as a duct.

[0010]

[Means for Solving the Problems]

 A duct / ceiling panel according to the present invention has a flat hollow rectangular tube structure in which upper and lower boards made of a heat insulating material, which are arranged in parallel at a small interval, and both side surfaces made of the same heat insulating material are integrated. The outer surface of the lower surface board is a ceiling finishing material, and the outer surface portion of the upper surface board is provided with a wiring guide member protruding in an appropriate pattern.

[0011]

[Action]

 The duct ceiling panel is arranged under the slab so that the bottom board is almost flush with other ceiling panels, and the hollow portions of the duct ceiling panels are connected to the air conditioner by appropriately connecting them in series. The conditioned air blown from the air conditioner to the hollow portion is introduced into the room. In other words, the ceiling panel that also serves as a duct forms a flat air flow passage, and this passage connects to the air conditioner, so that the conditioned air does not unnecessarily diffuse into the ceiling space. Moreover, since the ceiling panel that also serves as a duct is a heat insulating material, the heat loss of the conditioned air is extremely small.

Further, the wiring guide member is provided so as to project from the outer surface portion of the upper surface board of the ceiling panel that also serves as the duct, and the guide member is used to arrange the power cables, communication cables, and cables of OA equipment in an orderly manner. can do.

【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 suspension 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 suspension 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.

A breathable ceiling panel 7 and a 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 a 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 structure of the duct-combined ceiling panel 8 will be described in detail. As shown in FIG. 2, the panel 8 has an upper surface boat 81 and a lower surface board 82 made of a heat insulating material, which are arranged in parallel with each other with a small space therebetween, and are integrated with both side surface portions 83 made of a heat insulating material. In this case, the outer surface of the lower surface board 82 serves as a ceiling finishing material.

Here, as the heat insulating material board, one mainly composed of glass wool is preferable. Specifically, glass fiber reinforced aluminum kraft paper is attached to the surface of the high-density glass wool (outside of the duct), and the back surface (inside of the duct) is coated with black resin to prevent the fibers from scattering. Use the board. Moreover, the upper surface board 81, the lower surface board 82, and the side surface boards 83 are formed as one continuous board. In other words, a flat hollow cylinder can be formed by bending one board, and the ceiling panel 8 also serving as the duct can be manufactured by joining both edges of the board. Then, a surface material serving as a ceiling finishing material is attached at least to the outside of the surface corresponding to the lower surface board 82.

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 the duct, and the conditioned air is blown out into the room through the blowout portion provided as described below. 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 returned to the air conditioner. .

As shown in FIG. 2, a large number of wiring guide members 9 are formed in an appropriate pattern on the outer surface of the top board 81 of the ceiling panel 8 that also serves as a duct. The wiring guide member 9 of this embodiment is in the shape of a semicircular plate, and each member 9 is vertically provided on the upper surface of the duct 8b. A large number of wiring guide members 9 are arranged so as to form a straight line along both ends of the duct 8b, and are 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 under 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 and 12 are placed and wired on the upper surface of the ceiling panel 8 that also serves as a duct in the space above the ceiling. At that time, the cables 10, 11 and 12 are sorted and arranged in an orderly manner, and the positions of these cables are arranged. A wiring guide member 9 is provided in order to prevent it from coming off easily. That is, the wiring guide member 9 protruding from the outer surface portion of the upper surface board 81 serves as a means for regulating the wiring positions of the cables 10, 11, and 12. By using the guide member 9, various cables 10, It is possible to classify 11 and 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 an interval 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 routed 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.

The configuration of the portion that blows out the air pressure-fed from the air conditioner into the room can be implemented in various forms as in the following example. For example, the lower surface board in the ceiling panel that also serves as a duct is made of a breathable board, and the breathable board serves as an outlet. In this case, the ventilation board is made of a porous metal plate material such as punching metal or expanded metal, a porous plate material made of plastic, or a composite plate material in which these are combined with coarse cloth. The air is circulated in the duct without much resistance. Another example is a configuration in which another air outlet unit is sandwiched between the connecting portions of the ceiling panel that also serves as the duct.

[Effect of device]

 As described in detail above, in the ceiling panel that also serves as the duct of the present invention, the upper surface boat and the lower surface board made of a heat insulating material are arranged in parallel at a small distance and are integrated together with both side surfaces made of a heat insulating material. The outer surface of the lower surface board serves as a ceiling finishing material. Then, the general ceiling panel surface and the lower surface board of the duct and ceiling panel are placed flush with each other, and the hollow portions of these duct and ceiling panels are connected to each other to connect to the air conditioner. The air duct is configured.

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.

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.
