BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling and heating system using a ceiling panel in which a pipe unit is incorporated in a panel body.

[0002]

2. Description of the Related Art Recently, in a building in which a large number of ceiling panels are installed on a ceiling, a pipe unit is incorporated in the ceiling panel, and hot water or cold water is supplied to the pipe unit from a supply / discharge system provided in the ceiling or the like. Supplying and cooling is performed. In this case, a plurality of support bars are provided in parallel on the ceiling side of the building, and hook pieces project from specific standing pieces facing each other on the ceiling panel side. The length between the opposing sides on which the hook pieces are provided is made substantially equal to the interval between a pair of adjacent support bars. In order to install a ceiling panel on such a support bar, the ceiling panel is inclined, and is passed between adjacent support bars from below the support bar toward the back of the ceiling. Then, the ceiling panel is leveled and then lowered, and the hook piece formed on this ceiling panel is
Put it on the support bar.

In the process of installing the above-described ceiling panel, the pipe unit must be connected to a supply / discharge system provided on the ceiling side. However, the ceiling panel had to be suspended until the pipe unit was connected to the supply / drainage system, and it was dependent on humans to maintain the suspended state. Therefore, in this type of ceiling panel, the hanging piece is simply placed on the support bar on the building side, so that the ceiling panel can be easily installed on the support bar even when manually operated. In addition, if the hooking pieces are simply placed on the support beam, there is also an advantage that it becomes convenient when removing the ceiling panel for maintenance of the ceiling panel main body or maintenance of equipment behind the ceiling.

[0004]

In the conventional system as described above, the pipe unit is connected to the supply / discharge system on the ceiling side while lifting the ceiling panel by hand. There was a problem of power. In particular, since the ceiling panel is heavy, lifting it by hand is very hard work, and if you slip it by hand when you lift it, it can lead to serious injury. The same can be said for removing the ceiling panel for maintenance. On the other hand, if only the ease of installation is intended, there is a danger that the ceiling panel once installed will fall due to a large earthquake or the like. An object of the present invention is to provide a cooling and heating system for a ceiling, which can be easily installed on a ceiling while connecting a ceiling panel to a supply / discharge system and can be easily maintained.

[0005]

Assume system. The first invention suspends a large number of wires made of wires or the like on a support bar or other structure provided on the ceiling side while assuming the above system,
Of these wires, three or four wires are grouped into one set.
Corresponding to a single ceiling panel, and furthermore, the front ends of these wires are detachably hooked to the ceiling panel so that the ceiling panel can be suspended while supporting the ceiling panel at three or four points. The feature is that the length of the wire is specified so that when the ceiling panel is suspended by the wire, the ceiling panel is located below the support bar.

According to a second aspect of the present invention, the panel body of the ceiling panel comprises a square bottom surface and a standing piece standing on the periphery thereof, and a part of the standing piece is bent inward to form a reinforcing piece, which faces each other. The present invention is characterized in that a beam material is bridged between reinforcing pieces to be formed, and a wire is detachably hooked on a portion where the beam material and the reinforcing piece overlap.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A panel main body H shown in FIG. 1 is formed by processing a single plate into a sheet metal, and has a rectangular bottom surface 1 and long side upright pieces 2, 2 and short side upright pieces 3, 3 are formed. Reinforcing pieces 4, 4 horizontally bent inward are formed at the upper ends of the long side standing pieces 2, 2. By forming the reinforcing pieces 4 and 4 in this manner, the cross-sectional shape of the long-side standing pieces 2 and 2 becomes a channel shape, and accordingly, the strength of the long-side standing pieces 2 and 2 increases. . At the upper ends of the short side standing pieces 3, hook pieces 5, 5 horizontally bent outward are formed, and these hook pieces 5, 5 are attached to support bars on the building side described later. I try to hook.

Further, three beam members 6 are passed between the reinforcing pieces 4 at substantially equal intervals. As is clear from FIGS. 2 and 3, the beam member 6 has a concave portion 6a by recessing the central portion, and has horizontal portions 6b on both sides of the concave portion. The horizontal portion 6b is fixed to the back side of the reinforcing piece 4. Therefore, a space corresponding to the concave portion 6a is formed in the overlapping portion between the reinforcing piece 4 and the beam member 6. Of the beam members 6 as described above, only the beam member 6 extending to the center is shown in FIG.
As shown in FIG. 2, it is linked to the bottom surface 1 via a plurality of reinforcing members. By linking the central beam member 6 to the bottom surface 1 in this manner, the strength of the central portion of the panel main body H is increased, and the entire panel main body H is not twisted.

As shown in FIG. 1, a large number of sound absorbing holes 7 are formed on the bottom surface 1 of the panel body H, and a sound absorbing sheet 8 is attached so as to close the holes. Also,
A pipe unit U made of a synthetic resin shown in FIG. 4 is incorporated in the panel body H. The pipe unit U connects the supply-side main pipe 9, the return-side main pipe 10, and It consists of nine heat exchange pipes 11 to be connected. The heat exchange pipe 11 has flexibility and has a U-turn substantially at the center thereof. By making the central portion of the heat exchange pipe 11 U-turn in this way, the two main pipes 9 and 10 can be located on the same side as shown in the figure. At this time, the connectors 12, 13 provided on the main pipes 9, 10
However, they are located at the inner ends of both main pipes.
Further, the pipe unit U may be, for example, one in which the supply-side main pipe and the return-side main pipe are parallel to each other, and a heat exchange pipe is disposed between the two main pipes. In short, in this ceiling cooling and heating system, the form of the pipe unit U is not necessarily limited.

When assembling such a pipe unit U into the panel body H, the following is performed. That is, the pipe unit U is placed on the bottom surface 1 of the panel main body H with the connectors 12 and 13 positioned on one of the short sides of the panel main body H. A heat insulating material such as glass wool is spread over the pipe unit U placed on the bottom surface 1 so as to cover the pipe unit U. The panel unit H and the heat insulating material laid on the panel main body H in this manner constitute a ceiling panel of the present invention.

On the other hand, on the side of the building on which the above-mentioned ceiling panel is installed, as shown in FIG. The support bar 16 is fixed. This support bar 16
The vehicle travels in a direction penetrating the plane of the drawing, and when viewed from the entire ceiling, a large number of support bars 16 are arranged in parallel.
A pair of support bars 16, 16 are formed as a pair, and the interval between them is substantially equal to the length of the long side of the panel body H. A lighting fixture 17 such as a fluorescent lamp is held between the pair of supporting bars and the other pair of supporting bars.

Further, one end of a hanging wire 18 is fixed to each of the support bars 16, and a hook 19 shown in FIG. 3 is connected to the tip of the wire 18. Is elastically openable and closable. The wire 1 with the hook 19 connected to the tip in this way
8 is a set of four wires corresponding to each ceiling panel. The wire 18 corresponds to the wire of the present invention. On the other hand, as shown in FIG. 1 and FIG.
Nine hook holes 20 to 23 are provided. This hook hole 2
Numerals 0 to 23 are provided at overlapping portions of the reinforcing piece 4 and the beam member 6, and the retaining holes 20 to 23 correspond to the concave portions 6 a of the beam member 6. Moreover, the hook holes 20 to
A reinforcing plate piece 24 is bonded to the portion where 23 is provided. In FIG. 5, reference numeral 25 denotes a supply / discharge system provided behind the ceiling, which holds a supply pipe 25a and a return pipe 25b. The supply pipe 25a and the return pipe 25b are connected to a fluid supply source and a tank (not shown).

Next, a process of installing the above ceiling panel on the ceiling will be described. First, the connectors 12 and 13 of the pipe unit U are located on one short side of the panel body H. In this embodiment, the connectors 12 and 13 are located on the side of the locking holes 20 and 22 among the four locking holes. And the locking hole 2 located on the same reinforcing piece 4 side
The hook 19 of the wire 18 is hung on the 0 and 21 and the panel body H is horizontally elongated and suspended vertically as shown in FIG. With the panel main body H suspended vertically as described above, the connectors 12 and 13 of the pipe unit U are connected to the supply pipe 25a and the return pipe 25b of the supply / discharge system 25.

When the pipe unit U is connected to the supply / discharge system 25 as described above, the panel main body H is turned around the hook holes 20 and 21 to make it horizontal. In this state, the hook 19 is hooked in the other hooking holes 22 and 23, and the panel main body H is maintained horizontal as shown in FIG. The fact that the panel main body H is kept horizontal as described above means that the length of a set of four wires 18 suspending one panel main body H is all equal. When the panel main body H is hung horizontally as described above, this time, as shown in FIG. 8, if the panel main body H is inclined with one hooking piece 5 up and the other hooking piece 5 down, The hooking piece 5 side set above is positioned above the support bar 16. From this state, the other hooking piece 5 side is lifted in the direction of arrow 26, and is taken on the support bar 16, and further horizontally moved in the direction of arrow 27 from there,
Lower in 8 directions.

If the horizontal panel body H is lowered in the direction of arrow 28 as described above, the hook pieces 5 are hooked on the support bars 16 and the ceiling panel is installed on the ceiling as shown in FIG. . When the ceiling panel is once installed as shown in FIG. 5 and then removed for maintenance or the like, the ceiling panel can be easily removed by reversing the installation procedure described above. . That is, after the panel main body H shown in FIG. 5 is lifted in a horizontal state, it is slanted and passed through the support bar 16 from the lower hooking piece 5 side, and then the upper hooking piece 5 is removed. If it passes, the state of FIG. 7 can be obtained. From the horizontal state shown in FIG. 7, it is determined which hook holes 20 to 23 of the panel body H should be detached depending on whether the panel main body H is suspended horizontally or vertically. Depending on how the hooks 19 are removed, the panel body H is suspended horizontally or vertically.

Which direction is most suitable for suspension is
It depends on the environment of the room where the ceiling is located, and also on the purpose of maintenance. However, as in this embodiment, the panel body H is connected to the detachable hooks 19.
If it is hung with four wires 18 via the, it can be hung horizontally or vertically as required. As in this embodiment, the hook 5 of the panel main body H is connected to the support bar 1.
Just catching on 6 will never drop it under normal conditions. However, if the panel body H has a large swing such as jumping from the installation location due to an earthquake or the like,
The hook piece 5 may come off the support bar 16. However, even if they come off, the wire 18 completely prevents the panel body H from dropping,
It will be extremely safe.

If it is not necessary to select whether to suspend the panel body H horizontally or vertically, it is necessary to form a hook hole at a portion corresponding to three points of a triangle, for example. Further, hooks provided on the three wires may be hooked. That is, the panel body H is hung by the wire 18 to eliminate heavy labor caused by a person performing an installation work while lifting a heavy ceiling panel, and also to avoid danger such as when a hand slips. Is the main purpose. Focusing solely on achieving this primary objective, the panel body is
It is clear that they can be supported in terms of points. However, support bar 1
In the case where 6 has only a pair of parallel members as in this embodiment, the four-point support is more stable. If the support bars are in a grid shape and the panel body is fitted into each of the grids, there is not much difference between the three-point support and the four-point support.

If the wire 18 is directly hung from the building 14, the hanging position is set at 3 of the panel body.
It can correspond exactly to the point support position. As described above, depending on the position where the wire 18 is suspended, there is no difference between the three-point support and the four-point support from the viewpoint of achieving the main purpose. However, since the supply / discharge system 25 and the like are located behind the ceiling, there is a problem that the wire 18 cannot be hung freely at the intended place. Further, in this embodiment, since the hook holes 20 to 23 for hooking the hook 19 are formed in the overlapping portion of the reinforcing piece 4 and the beam member 6, the strength of the hook holes 20 to 23 can be sufficiently maintained. Moreover, these retaining holes 20 to 23
Since the reinforcing plate piece 24 is bonded to the portion of the reinforcing piece 4 in which is formed, the strength is further increased.

In any case, if the ceiling panel is installed as described above, the room is heated or cooled by the hot or cold water supplied from the supply / discharge system 25. Since fluid is supplied to each ceiling panel in this way,
You may need to maintain each ceiling panel. In such a case, if the panel main body H is suspended as shown in FIG. 6, it is not necessary to go into the ceiling for maintenance, and the maintenance can be performed efficiently. Further, since it is not necessary to consider that a person enters the ceiling, the space above the ceiling can be used effectively.

[0020]

According to the cooling and heating system of the first invention,
Ceiling panels can be easily installed without much effort. Also, even if the ceiling panel slips from the hand during the installation work, the drop of the panel can be prevented by a wire material such as a wire, so that the safety is extremely high. Furthermore, even if a severe earthquake occurs and the ceiling panel falls from the ceiling, the wires support the ceiling panel, so that people are not injured. In addition, when the ceiling panel is supported at four points by wires, the ceiling panel can be hung horizontally or vertically. Therefore, the suspended state of the ceiling panel can be freely selected according to room conditions, the purpose of maintenance, and the like. In addition, at the time of maintenance, it is not necessary to go into the back of the ceiling only by suspending the panel body, so that the maintenance work can be performed efficiently. Furthermore, since it is not necessary to consider that a person enters the ceiling, the space above the ceiling is effectively used. According to the cooling and heating system of the second invention, the strength of the panel body connecting the wires can be increased.
