Description

  The present invention relates to a ceiling panel using a latent heat storage material and a method for attaching the ceiling panel.

  Conventionally, in the technical field of such flooring and ceiling materials, research and development to make more effective use of thermal energy generated during indoor heating and natural energy such as sunlight has been actively pursued. Energy conservation and ecological measures based on these research and development are being taken.

  For example, a heat storage plate filled with a latent heat storage material is placed on both sides of a hollow panel through which hot water or cold water flows, and hot water or cooling is flowed through the hollow panel to store or cool the latent heat storage material. A ceiling air conditioner for heating or cooling has been proposed. This ceiling air-conditioning / heating device is suspended from a rod via a fishing fitting (see, for example, Patent Document 1).

  According to this ceiling air conditioner, when warm water is passed through the hollow panel, the latent heat storage material can store the heat of the warm water, and the heat stored in the room can be radiated from the heat storage plate filled with the latent heat storage material. . On the other hand, when cold water is allowed to flow through the hollow panel, the latent heat storage material cools the heat of the cold water, and the indoor heat can be absorbed from the heat storage plate filled with the latent heat storage material.

Hereinafter, the present invention will be described based on the present embodiment with reference to the drawings.
[First Embodiment]
FIG. 1 is a schematic exploded perspective view of a ceiling panel according to a first embodiment of the present invention, and FIG. 2 is a sectional view of the ceiling panel shown in FIG. 1 attached to the ceiling surface. These are AA arrow sectional drawing of FIG. 1, (b) BB arrow sectional drawing of FIG. FIG. 3 is an exploded perspective view of the ceiling panel fixture shown in FIG. 1.

  The ceiling panel 100 according to the present embodiment is attached so as to cover at least a part of the ceiling surface cf. The ceiling panel 100 includes a ceiling panel body 1 and a pair of fixtures 40 and 40.

  The ceiling panel body 1 has a mat member 10 formed with a flow path 11a through which a heat exchanging medium F such as a heating medium or a cooling medium is formed, and stores the heat of the heating medium by contacting the mat member 10 or a cooling medium. A latent heat storage material 20 that cools the heat of the battery, and a panel recess 30 that includes a mating member 10 and the latent heat storage material 20 in the back surface and a decorative surface formed on the front surface. .

  The panel material 30 is a rectangular flash panel having a long side and a short side. A frame member 32 is attached to the panel member 30 along the peripheral edge of the back surface of a bottom plate member 34 made of plywood, and a surface decorative material 35 such as oak, birch, beech, teak or the like is provided on the surface. It is stuck. When the ceiling panel 100 is attached, the surface of the surface decorative material 35 becomes a decorative surface facing downward together with the ceiling surface cf.

  Further, the recess formed by the bottom plate member 34 and the frame member 32 becomes an accommodating recess 31 for accommodating the mat member 10 and the latent heat storage material 20. In the housing recess 31, a plurality of bars 33 that divide the housing recess 31 are arranged along the short side direction of the panel member 30. Each crosspiece 33 is connected to a pair of frame members 32 and 32 arranged along the long side direction. The latent heat storage material 20 is disposed and accommodated in each part of the accommodation recess 31 partitioned by the crosspieces 33, and covers the entire storage recess 31 (that is, the opening of the panel material 30) in a state where the latent heat storage material 20 is accommodated. A mat member 10 is disposed.

  The latent heat storage material 20 accommodated in the accommodation recess 31 stores the heat of the heating medium when the heating medium flows in a flow path 11a of the mat material 10 described later, and the cooling medium flows in the flow path of the mat material 10. In this case, the heat of the cooling medium is stored.

Specifically, the latent heat storage material 20 is preferably one that melts (phase changes) at a melting point (phase change temperature) of 20 ° C. to 30 ° C., for example, sodium sulfate hydrate, calcium chloride hydrate. , Paraffin (C ₁₇ H ₃₆ , C ₁₈ H ₃₈ ), polyethylene glycol (molecular weight: 500 to 1000), and the like. The material is particularly limited as long as it can store heat at the melting point or higher. It is not a thing.

  As a more preferable latent heat storage material 20, a latent heat storage material that becomes a gel at a temperature equal to or higher than the phase change temperature when stored directly in the storage recess 31 can be exemplified. Since the solid state changes to the gel state at the phase change temperature or higher, the latent heat storage material 20 can be easily held in the housing recess 31 even when the phase change temperature is exceeded. Examples of such a latent heat storage material include sodium sulfate decahydrate, Calslip manufactured by JSR, high-viscosity capsule manufactured by Miki Riken Kogyo, and latent heat storage manufactured by Mitsubishi Cable Industries, Ltd. Materials MHSR series can be mentioned.

  The mat member 10 has a size of about 600 mm × 1800 mm × 5 mm, for example, and includes a plate-like heat insulating material 13 formed of foamed resin or the like, and the heat insulating material 13 includes a plurality of small joists 12 disposed therein. Yes. The small joist 12 is fixed to a part of the crosspiece 33 of the panel member 30 in a state where the mat member 10 is disposed in the housing recess 31. The plurality of small joists 12 are arranged in a staggered manner along the short side direction so that a housing groove for housing the heat exchange tube 11 can be continuously formed on the surface of the heat insulating material 13.

  Such small joists 12 preferably act as reinforcing ribs that maintain the strength of the mat member 10. The mat material 10 is integrated with the panel material 30 containing the latent heat storage material 20 so as to cover the latent heat storage material 20 by a mat material mounting member 48 such as a screw or a nail at a position where the small joist 12 and the crosspiece 33 are in contact with each other. Is attached.

  Furthermore, heat exchange medium F made of a heating medium or a cooling medium circulates in the mat material 10 on the surface of the heat insulating material 13 of the mat material 10 that contacts the latent heat storage material 20. An accommodation groove for accommodating the tube 11 is formed, and the heat exchange tube 11 is accommodated in the accommodation groove. The heat exchange tube 11 is a flexible resin or rubber tube, and is connected to a medium supply unit (not shown) that selectively supplies a heating medium or a cooling medium. The heating medium or cooling medium supplied from the medium supply unit and circulated in the mat member 10 is returned to the medium supply unit, heated or cooled again, and supplied to the heat exchange tube 11 as the heat exchange medium F.

  Here, when a heating medium is used, a medium such as water heated to a temperature higher than at least the phase change temperature of the latent heat storage material 20 described above is used as the heating medium. Thereby, the heating medium flowing through the heat exchange tube 11 heats the latent heat storage material 20, and the latent heat storage material 20 is stored. On the other hand, when a cooling medium is used, a medium such as water cooled to a temperature lower than the phase change temperature of the latent heat storage material 20 described above is used as the cooling medium. Thereby, the cooling medium which flows into the heat exchange tube 11 cools the latent heat storage material 20, and the latent heat storage material 20 is stored cold.

  Here, when the ceiling panel body 1 is attached to the ceiling surface cf, condensation is likely to occur between the ceiling panel body 1 (particularly the mat member 10) and the ceiling surface cf. In particular, when a cooling medium is used, such a phenomenon becomes remarkable.

  Therefore, in the present embodiment, the following fixture 40 is adopted as a fixture for fixing the ceiling panel body 1 to the ceiling surface cf. Specifically, the fixture 40 is for fixing the ceiling panel body 1 to the ceiling surface cf on both sides in the long side direction of the ceiling panel body 1, and in a state where the ceiling panel body 1 is fixed to the ceiling surface cf, The space S is formed between the back surface of the ceiling panel body 1 and the ceiling surface cf.

  Thus, the fixture 40 has the function of forming the space S between the ceiling surface cf and the back surface of the ceiling panel body 1 while having the function of fixing the ceiling panel body 1 to the ceiling surface cf. Thus, since the space S is formed between the ceiling surface cf and the back surface of the ceiling panel body 1 with the ceiling panel body 1 attached (fixed) via the fixture 40, the ceiling surface cf and the ceiling Generation | occurrence | production of the dew condensation between the back surfaces of the panel main body 1 can be prevented.

  In the present embodiment, the fixture 40 has a hinge structure that includes a first hinge member 42 and a second hinge member 43 that are pivotally connected to each other. A spacer 41a made of, for example, a wooden square is attached via a nail, a screw, an adhesive, or the like. In addition, the 1st fixing member 41 said by this invention is corresponded to the member integrally comprised by the 1st hinge member 42 and the spacer 41a, and the 2nd fixing member said by this invention is 2nd. It corresponds to the hinge member 43.

  As shown in FIG. 3, each of the first hinge member 42 and the second hinge member 43 is provided with a fixing hole (not shown in FIG. 3) for fixing them with screws, nails or the like. 42c and 43c are formed, and cylindrical shaft insertion portions 42a and 43a are formed on the sides thereof.

  In a state where the plate-like portions 42c and 43c are overlapped, the shaft insertion portions 42a and 43a are arranged on the same pivot axis, and the shaft portion 44 is inserted into the shaft insertion portions 42a and 43a, and formed at the tip of the shaft portion 44. By screwing the shaft fixing screw 47 into the threaded groove 44b, the first hinge member 42 and the second hinge member 43 can pivot about the shaft portion 44 as a central axis. Further, if the shaft fixing screw 47 is removed from the screw groove hole 44b at the tip of the shaft portion 44 and the shaft portion 44 inserted into the shaft insertion portions 42a and 43a is removed, the first fixing member 41 is removed from the fixture 40. Can be removed.

  In this embodiment, particularly, as shown in FIGS. 2A and 2B, the spacer 41 a is attached to the first hinge member 42, so that the shaft portion is also provided between the ceiling surface cf and the shaft portion 44. A working space for attaching / removing 44 is formed. Thereby, the 1st fixing member 41 can be easily removed from the 2nd hinge member 43 of the fixing tool 40, and these can be easily connected again.

  Here, the spacer 41a constituting a part of the first fixing member 41 is fixed to the ceiling surface cf, and the second hinge member 43 as the second fixing member is fixed to the back surface of the ceiling panel body 1. . By adopting such a configuration, the first fixing member 41 is detached from the fixing tool 40 and attached in advance to a desired position on the ceiling surface, so that the ceiling panel body 1 can be easily placed on the desired ceiling surface cf. Can be aligned. Further, the second hinge member 43 is pivotally moved together with the ceiling panel body with respect to the first hinge member 42 by being connected to the first fixing member 41 and the second hinge member 43 (second fixing member). By doing so, the ceiling panel can be easily attached to the ceiling surface cf. Details of the mounting method will be described later with reference to FIG.

  In FIG. 1, at one end 1 a of the ceiling panel main body 1, the first hinge members 42, 42 of the first fixing member 41 to be attached are hinge members 42 orthogonal to the pivot axis of each first hinge member 42. A pair of second hinge members 43 and 43 connected to the spacer 41a are attached to the spacer 41a so that the shaft insertion portion 42a is closer to the same direction side (one direction side) than the center line of the second hinge member. The shaft insertion portion 43a is attached to the ceiling panel body 1 so that the shaft insertion portion 43a is closer to the same direction side (the other direction side) than the center line of the hinge member 43 orthogonal to the pivot axis of the member 43.

  Accordingly, the first hinge members 42 and 42 of the first fixing member 41 attached to the ceiling surface and the second hinge member 43 attached to the ceiling panel main body 1 shown in FIG. , 43, the ceiling panel body 1 is slid from one side, and the shaft insertion portions 43a, 43a of the second hinge members 43, 43 are inserted into the shafts of the first hinge members 42, 42. The first hinge members 42, 42 and the second hinge members 43, 43 can be easily connected by the shaft portion 44 while being pressed against the portions 42 a, 42 a.

  On the other hand, at the other end 1 b of the ceiling panel body 1, the first hinge members 42, 42 of the first fixing member 41 to be attached are such that the shaft insertion portions 42 a, 42 a are closer to the inside than the ceiling panel body 1. Thus, it is attached to the spacer 41a. Corresponding to this, the pair of second hinge members 43, 43 have shaft insertion portions 43 a, 43 a attached to the outside of the ceiling panel body 1.

  Accordingly, the first hinge members 42 and 42 of the first fixing members 41 and 41 and the ceiling panel body 1 are attached so as to be in a state shown in FIG. When the second hinge members 43, 43 are connected, the second hinge members 43, 43 are arranged so as to sandwich the first hinge members 42, 42, so that they are temporarily fixed (FIG. 4). The positional deviation of the ceiling panel body 1 with respect to (shown in (c)) can be prevented.

  Specifically, pin insertion holes 42b and 43b are formed in the shaft insertion portions 42a and 43a formed in the first and second hinge members 42 and 43 described above, and the shaft portion 44 has a shaft. Pin engaging holes 44a and 44a are formed at positions corresponding to the pin insertion holes 42b and 43b in a state where the portion is inserted into the shaft insertion parts 42a and 43a.

  With the shaft portion 44 inserted into the shaft insertion portions 42a and 43a, the pin engagement holes 44a and 44a of the shaft portion 44 are aligned with the pin insertion holes 42b and 43b, and the pin insertion holes 42b and 43b are aligned. The tip of the U-shaped pin 46 is engaged with the pin engaging holes 44a, 44a through the pin. Thereby, the pivot of the first and second hinge members 42 and 43 can be restricted (locked).

  Thus, with the ceiling panel 100 attached to the ceiling surface cf, the pivot of the first and second hinge members 42 and 43 attached to both sides of the ceiling panel body 1 is restrained by the pivot restraint mechanism. Thereby, the bending by the dead weight of the ceiling panel 100 can be suppressed. In particular, in the present embodiment, the ceiling panel body 1 is fixed by a pair of fixtures 40, 40 on both sides along the long side direction, so that the center of the ceiling panel body 1 is usually easily bent, By providing the pivot restraint mechanism (lock mechanism) described above, it is possible to more reliably suppress such bending of the ceiling panel body 1.

  In the present embodiment, the pivot of the first and second hinge members 42 and 43 is restrained by the pin 46 shown in FIG. 3 as the pivot restraint mechanism (lock mechanism). These mechanisms are not particularly limited as long as the pivot of the second hinge members 42 and 43 can be restrained.
