Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a duct / ceiling panel used for constructing a ceiling air-conditioning system having a structure in which a ceiling and an air-conditioning duct are applied to a general building, and particularly to a connecting structure for communicating a plurality of duct / ceiling panels. Regarding

[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), and the work is generally performed in the following procedure. The duct is manufactured in advance based on the design document. 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.

In this independent duct system, there are a beam penetrating structure in which a duct is arranged so as to penetrate a beam in a ceiling space, and an under-beam structure in which a duct disposing space is provided below the beam.

In addition, 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 positioned. It has a structure that blows conditioned air into the room from the air outlet provided in the room.

[0005]

[Problems to be Solved by the Invention] In the above-described ceiling structure of the independent duct system, not only is it difficult to pre-manufacture the duct including the complicated bending point, but also the work of mounting the duct on the lower surface of the slab and connecting them to each other is not required. It will be a manual work that is tailored to the site, and it will be a very large-scale and troublesome construction as a whole. In addition, the ceiling height will be low even if the above-mentioned beam penetration structure or the under-beam structure is the same floor space as the duct installation space, so the floor height must be set high in order to achieve the prescribed ceiling height. . 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 one by one, or the inspection port must be made in advance at a certain point, and the narrow ceiling can be used from there. It was very inconvenient because I had to go in and work on it.

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.

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 system and has a structure having a small influence on the floor height, and the heat loss. It is to provide a duct / ceiling panel connection structure for constructing a ceiling air-conditioning system that can realize efficient air-conditioning and can easily change layouts such as partial increase / decrease in air volume.

[0008]

[Means for Solving the Problems]

 Therefore, in this invention, the upper and lower boards made of a heat insulating material, which are arranged in parallel at a small distance, and the both side surfaces made of the same heat insulating material are integrated to form a flat hollow rectangular tube structure. In addition to providing a duct ceiling panel in which the outer surface of the lower surface board serves as a ceiling finishing material, a socket made of a thin plate material is provided in a hollow square tube structure of a size that fits exactly in the hollow portion of the duct ceiling panel. Insert the socket into one end of the duct / ceiling panel halfway to join it, and insert the other end of the duct / ceiling panel with the same structure into the protruding part of the socket to connect the two duct / ceiling panels. The structure is such that they are butted and connected.

[0009]

[Action]

 The duct ceiling panel is arranged under the slab so that the bottom board 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 introduced into the room. In other words, the ceiling panel that also serves as a duct forms a flat air circulation path, and this path connects to the air conditioner, so that the conditioned air does not unnecessarily diffuse into the ceiling space. Also, since the ceiling panel that also serves as a duct is made of a heat insulating material, the heat loss of the conditioned air is extremely small.

To connect two ceiling panels that also serve as ducts to each other, it is only necessary to fit the sockets on the inner circumferences of the abutting portions of the two, and it is possible to easily remove and reconnect the sockets after the connection. .

【Example】

 1 to 3 show a ceiling air-conditioning system constructed by using a duct-combined ceiling panel and its connecting structure 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 projecting portions 6a of each T-bar 6 are all located in the same horizontal plane.

A ceiling panel 7 and a duct-use ceiling panel 8 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 duct / ceiling ceiling panel 8 is also installed so as to be placed on the horizontal overhanging portions 6 a of the two T-bars 6 on both sides and to be stretched 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.

The structure of the ceiling panel 8 that also serves as a duct 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 ceiling panel 7 and the ceiling panel 8 which also serves as a duct 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. Go. The hollow portion of the ceiling panel 8 that also serves as a duct is connected and connected as follows, and the air flow passage configured by the ceiling panel 8 that also serves as a duct is used as an air supply duct for the air conditioning system. 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 conditioned air that is sent under pressure is sent into the interior of the ceiling panel 8 that also serves as a duct.

Next, the connecting structure of the duct / ceiling panel 8 which is the main part of the present invention will be described in detail with reference to FIGS. 4 and 5.

In the present invention, a separately manufactured socket 11 is used to connect the ceiling panels 8 that also serve as ducts. The socket 11 of this embodiment is made of an iron plate and has a hollow cylindrical shape having a size that fits exactly into the flat rectangular tube of the ceiling panel 8 which also serves as a duct. 12 is attached integrally. The length of the socket 11 in the cylinder axis direction is only required to substantially connect the two duct / ceiling ceiling panels 8 to each other, and is much shorter than the duct / ceiling ceiling panel 8. Further, the vertical ribs 12 are attached along the cylinder axis direction so as not to disturb the air flow in the hollow portion. Depending on the dimensions of the duct / ceiling panel 8, the socket 11 may be provided with a plurality of vertical reinforcing ribs 12.

The socket 11 is fitted into one end of the duct / ceiling panel 8 up to about half, and is joined to the inner surface of the panel 8 with an adhesive or the like. This socket 11 is attached in advance. That is, the duct / ceiling panel 8 having the socket 11 attached in advance at one end is connected to the construction site. As shown in FIG. 5, one end of the duct / ceiling panel 8 on which the socket 11 is attached and the other end of the duct / ceiling panel 8 on the side without the socket 11 are butted against each other to form a socket. The protruding portion of 11 is fitted into the other ceiling panel 8 that also serves as a duct. As a result, one socket 11 is fitted over both of the abutted ends of the two duct / ceiling ceiling panels 8, and the two duct / ceiling ceiling panels 8 are connected and connected via the sockets 11. At this connecting portion, the side of the socket 11 bonded to the inner surface of the panel is arranged upstream of the flow in the direction of air blow from the air conditioner 9. If so, 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 ceiling panel 8 also serving as the duct becomes extremely simple, but also the ceiling panel 8 also serving as the duct is disconnected in accordance with the layout change and maintenance inspection. The work and the reconnection work are extremely easy.

Although the above description does not refer to the configuration of the portion that blows out the air that is pressure-fed from the air conditioner 9 into the room, the configuration of the outlets and the suction ports of the conditioned air can be varied as in the following examples. Can be implemented in. For example, the lower surface board in the duct / ceiling panel is made of a breathable board, and the vent board serves as an outlet. In this case, as the ventilation board, use a porous metal plate material such as punched metal or expanded metal, a porous plate material made of plastic, or a composite plate material that combines these with coarse cloth. , Allow air to flow through the duct inside and outside without much resistance. As another example, there 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 above in detail, in the present invention, a duct / ceiling panel made of a heat insulating material having a flat hollow cylinder structure whose lower surface also serves as a finishing material is provided, and it is fitted exactly in the hollow portion of the duct / ceiling panel. A socket made of thin plate material with a hollow cylindrical structure of a size that fits is provided so that the general ceiling panel surface and the lower board of the ceiling panel that also serves as a duct are flush with each other. By fitting the sockets over both of the butted ends, the hollow portions of the ceiling panel that also serves as the duct are interconnected to form the air supply duct of the air conditioner.

Therefore, the ceiling finishing surface is lower than the beam lower surface by the thickness dimension of the duct / ceiling panel, which is flat, and the ceiling height is the same as that of the conventional independent duct type ceiling structure if the floor 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. In particular, since it is extremely easy to connect and separate the ceiling panels that also serve as ducts, it is possible to freely set and change the arrangement of the ceiling panels that also serve as ducts. 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 to the outside from 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.
