Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a duct / ceiling panel used for constructing a wide-area blow-out type ceiling air conditioning system having a structure in which a ceiling and an air conditioning duct are fused, which is applied to a general building, and more particularly, to a plurality of duct / ceiling panels. The present invention relates to a connecting structure for communicating with each other.

[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 that is separate from the ceiling panel is installed in the space between the concrete slab and the ceiling panel (finishing material). Generally, the duct is manufactured based on the design document in advance. . Each duct is fixed to the bottom surface of the slab with suspension bolts. Set the outlets and connect the ducts. Insulate the outer circumference of the duct. After the above steps are completed, a ceiling panel is attached to the lower part of the duct by another support structure to connect the air outlet and the duct. Work will proceed according to the following procedure. In this independent duct system, there are a beam penetrating structure in which a duct is arranged so as to penetrate a beam in the ceiling foot, and an under-beam structure in which a duct disposing space is provided below the beam.

The ceiling chamber air supply system uses the entire ceiling space as an air supply chamber of an air conditioner, and there is no independent air supply duct, and the entire ceiling space serves as a duct space, and the ceiling panel surface is appropriately adjusted. It has a structure that blows conditioned air into the room from the outlet provided at the position.

[0004]

[Problems to be solved by the device]

 In the above-mentioned independent duct type ceiling structure, not only is it difficult to pre-manufacture ducts that include complicated bends, but the ducts are attached to the bottom surface of the slab, and the work of connecting them to each other is a manual operation that is site-specific. Therefore, it will be a very large scale and troublesome construction as a whole. In addition, the ceiling height will be low even if the floor height is the same for the space where the ducts are installed, regardless of the beam penetration structure or the under-beam structure. I won't. Furthermore, with the independent duct system, when repairing or maintaining the air conditioning duct once installed in the ceiling, the ceiling panel must be peeled off or an inspection port must be made in advance at a certain point, and a narrow ceiling must 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 dispersed 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 a highly 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 outlet layout of the conventional ceiling air conditioning system is not designed according to the individual indoor usage pattern, but the outlets are arranged at appropriate intervals as a standard layout. 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 speed of the air blowing from it will be high, and the inconvenience that the cold air directly hits the person during cooling will occur.

Therefore, it is conceivable to change the outlet layout of the ceiling air-conditioning system according to the usage form in the room, but the work is extremely troublesome in the above-mentioned independent duct system. With the ceiling chamber air supply method, it is relatively easy to change the layout, but it is not realistic to repeat the ceiling work as the indoor usage pattern changes frequently.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is a structure which is comparable to the conventional ceiling chamber air supply method and has a structure having a small influence on the floor height, and is effective in reducing heat loss. In order to build a wide-area air-conditioning ceiling air-conditioning system that can realize efficient air-conditioning, can evenly air-condition the entire room with weak airflow, and can easily change the layout such as partial increase or decrease in air volume. The purpose is to provide a connecting structure for ceiling panels that also serve as ducts.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a duct / ceiling panel having a flat hollow cylindrical structure in which a lower surface is made of a breathable panel that also serves as a ceiling finishing material, and upper surfaces and both sides are made of heat insulating material. A fitting protrusion is integrally formed on the upper surface of the heat insulating material and one end portion of both side surfaces with a structure that divides the wall thickness into two parts. The fitting concave portion that fits with the fitting convex portion of the ceiling panel that also serves as the duct is formed integrally.

[0010]

[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 conditioned air blown from the air conditioner to the hollow portion is blown out 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 blowing surface. The ceiling panel itself that also serves as a duct forms a flat air flow passage, which connects to the air conditioner and prevents the conditioned air from unnecessarily diffusing into the ceiling space. Moreover, since the upper surface and both side surfaces of the ceiling panel that also serves as the duct are heat insulating materials, the heat loss of the conditioned air is extremely small. The breathable panel is also a ceiling finishing material, and by using a lot of duct-cum-ceiling panels, it is possible to make the entire area of the ceiling surface a blowing surface for conditioned air.

In order to connect and connect a plurality of ceiling panels that also serve as ducts, it is sufficient to fit one of the fitting protrusions and the other fitting recess.

【Example】

 1 to 5 show a wide-area blow-out type ceiling air-conditioning system constructed by using a duct-combined ceiling panel according to an embodiment of the present invention. In each figure, 1 is a concrete slab that constitutes the ceiling and floor, 2 is a pillar, and 3 is a beam made of H-shaped steel.

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. These C-channels 5 correspond to an intermediate cross member, and the distance between the slab 1 and the C-channel 5 is almost equal to the height dimension of the beam 3.

The T-bar 6 is fixed by welding or the like so as to horizontally extend over the lower surfaces of the large number of C channels 5. The T-bar 6 is arranged in an inverted T-shape, with its horizontal overhanging portion 6a facing down. Further, as shown in FIGS. 1 and 3, a large number of T-bars 6 are arranged in parallel at predetermined intervals. Further, the horizontal overhanging portions 6a of each T-bar 6 are all located in the same horizontal plane.

A ceiling panel 7 and a ceiling panel 8 also serving as a duct are mounted using the T bar 6 as a supporting member. In this embodiment, a normal ceiling panel 7 and a duct / combined panel 8 are alternately installed in each section of each T-bar 6 installed in a parallel pattern. The ceiling panel 7 is a normal ceiling finishing panel material, the width of which is approximately equal to the installation interval of the T-bars 6, which is inserted between the T-bars 6, and both sides of the ceiling panel 7 are placed on the horizontal overhanging parts 6a of the T-bars 6. It is installed so that it can be placed on.

The ceiling panel 8 which also serves as a duct is also placed on the horizontal overhanging portions 6 a of the two T-bars 6 on both sides and is installed so as to be laid over this. The ceiling panel 8 that also serves as a duct has a flat hollow cylindrical structure in which the thickness of the ordinary ceiling panel 7 is increased, and has a thickness (height) that can be accommodated between the horizontal overhang 6a of the T bar 6 and the C channel 5. There is.

As is apparent from FIG. 3, the lower surface 8 a of the duct / combined panel 8 is flush with the other ceiling panels 7 and serves as a ceiling finishing material together with the ceiling panels 7. The lower surface 8a is made of a porous metal panel material such as punched metal or expanded metal, a porous molded panel material made of plastic, or a panel material that is a combination of these materials and rough cloth. It is a panel. This breathable panel 8a also serves as the air outlet or the air inlet of the air conditioner. The upper surface and both side surfaces of the air-permeable panel 8a, which constitutes a flat hollow cylinder on the upper surface side, are made of a heat insulating material 8b. In other words, it has a structure in which the breathable panel 8a is arranged on the open surface of the heat insulating material 8b having a U-shaped cross section. The heat insulating material 8b is made of, for example, glass wool or foamed resin. Further, the breathable panel 8a is subjected to a dew-proofing treatment such as spraying a paint having a moisture absorption effect so as to prevent the dew condensation on the breathable panel 8a even during cooling.

The ceiling panel 7 and the duct-cum-ceiling panel 8 are divided into appropriate lengths in the longitudinal direction of the T-bar 6, and are connected to each other while being set on the horizontal overhanging portion 6a of the T-bar 6. To go. The hollow portion of the duct / ceiling panel 8 serves as an air circulation path for air conditioning as described below, but has a connecting structure that prevents air leakage at the joint between the adjacent duct / ceiling panels 8.

In this embodiment, the air flow passage configured by the ceiling panel 8 also serving as the duct is used as an air supply duct of the air conditioning system, and the breathable panel 8a is used as an outlet (a wide outlet surface). . That is, as shown in FIG. 2, the fan outlet of the air conditioner 9 installed outdoors and the air flow passage of the duct / ceiling panel 8 interconnected with each other are connected by an appropriate connecting mechanism 10, and the air conditioner 10 is connected. Air-conditioned air sent from the inside is sent into the interior of the ceiling panel 8 that also serves as a duct, and is blown out into the room from the breathable panel 8a. Of course, the ceiling panel 8 that also serves as a duct can be used as a return air suction port and a return duct, and the installation pattern of the ceiling panel 8 that serves as a duct can be used to freely set the installation pattern of the blowing surface and the suction surface. it can.

FIG. 6 shows a connecting structure of the ceiling panel 8 also serving as the duct, which is a main part of the present invention. As described above, the upper surface and both side surfaces of the ceiling panel 8 that also serves as the duct are formed of a heat insulating material, but as shown in FIG. 6, only one half of the thickness of the heat insulating material 8b is at one end of the heat insulating material 8b. Is integrally formed with a protruding protrusion 11 in a U-shape, and the other end of the heat insulating material 8b has a U-shape only in the outer half of the wall thickness, contrary to the fitting protrusion 11. The fitting recessed portion 12 that protrudes is integrally formed. Then, when the fitting convex portion 11 of one ceiling panel 8 also serving as the duct and the fitting concave portion 12 of the ceiling panel 8 also serving as the duct are butted, the fitting convex portion 11 and the fitting concave portion have a so-called interlocking structure. 12 fits snugly, and both hollow parts communicate. At this connecting portion, the fitting convex portion 11 is arranged so as to be on the upstream side of the flow with respect to the direction of air blown from the air conditioner 9. Then, there is no risk of air leakage even if no measures are taken.

According to the above connecting structure, not only the arrangement and connecting work of the duct / ceiling ceiling panel 8 becomes extremely simple, but also the connection of the duct / ceiling panel 8 is removed in accordance with the layout change and maintenance inspection. The work and the reconnection work are extremely easy.

[Effect of device]

 As described in detail above, according to the present invention, a ceiling / duct type ceiling panel having 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 sides are made of heat insulating material, In addition, a fitting projection is integrally formed on the upper surface of the heat insulating material and one end portion of both side surfaces with a structure that divides the wall thickness into almost two parts, and the same upper surface and the other end portion of both side surfaces have the same structure. The fitting concave portion that fits with the fitting convex portion of the ceiling panel that also serves as the duct is integrally formed. Then, the general ceiling panel surface and the air-permeable panel of the duct / ceiling panel are arranged so as to be flush with each other, and the fitting convex portion and the fitting concave portion of the duct / ceiling ceiling panel are fitted together. By connecting the hollow parts to each other and connecting them to the air conditioner, the ceiling panel that also serves as a duct functions as an air supply duct and an air outlet surface of the air conditioner.

Therefore, the ceiling finishing surface is lower than the lower surface of the beam by the thickness dimension of the duct / ceiling ceiling panel, which is lower than that of the conventional independent duct type ceiling structure if the ceiling height is the same. 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. Especially, since the connection and separation of the ceiling panels that also serve as ducts can be performed very easily, the arrangement of the ceiling panels that also serve as ducts can be freely set and changed, and the work of changing the arrangement pattern of the air supply duct and the blowing surface in the room. Also, maintenance work is extremely easy.

Further, compared with the structure of the conventional ceiling chamber air supply system, the conditioned air does not leak out of the room through an unintended gap portion of the building, and the concrete slab does not absorb much heat of the conditioned air. The heat loss as an air conditioning system becomes extremely small. In addition, the problem that the capacity of the Amai chamber is too large is eliminated, and the rise time from the start of operation of the air conditioner to the time when effective conditioned air reaches the room is shortened.
