Description

  The present invention relates to an interior board suitable for use in an interior of a building and a method for using the interior board.

2. Description of the Related Art Conventionally, an interior board material that constitutes a floor board, a ceiling board, a wall board, and the like of a building and contains a heat storage material is known (for example, see Patent Document 1). As the heat storage material contained in the interior plate material, a heat storage material having a phase change temperature suitable for the use period of the interior member is selectively used from among a plurality of heat storage materials having different phase change temperatures. In the winter season, for example, when preventing indoor cooling, a heat storage material having a phase change temperature of, for example, 20 ° C. is used. In this case, when the room temperature becomes 20 ° C. or less, the heat storage material changes from the liquid phase to the solid phase, and the heat stored in the heat storage material is released into the room due to the solidification of the heat storage material. Further, for example, in order to prevent indoor overheating in the summer, a heat storage material having a phase change temperature of, for example, 30 ° C. is used. In this case, when the room temperature becomes 30 ° C. or higher, the heat storage material changes from a solid phase to a liquid phase, and the heat of the room is absorbed by the heat storage material due to melting of the heat storage material. The room temperature can be kept substantially constant by the absorption of heat in the room by the heat storage material and the release of heat to the room.
Japanese Patent Laid-Open No. 2001-140437 (page 3-5, FIG. 1)

  However, since the interior plate material contains a heat storage material having a phase change temperature suitable for the use period, for example, the interior plate material used in summer cannot be used in winter. For this reason, it is necessary to form the exclusive interior board | plate material containing the thermal storage material which has a phase change temperature suitable for the period for every utilization period of an interior board | plate material, and causes an increase in manufacturing cost.

  Accordingly, an object of the present invention is to provide an interior board material that can be used at different times without causing an increase in manufacturing cost and a method for using the same.

  In order to solve the above-mentioned problem, the invention according to claim 1 is an interior plate member provided with a plate member used for interior of a building, and the plate member has an indoor heat absorption and It contains a heat storage material that releases the absorbed heat into the room by a phase change corresponding to the temperature change in the room, and has a phase change temperature different from the phase change temperature of the heat storage material on the other side. The heat storage material which has is contained.

  The invention according to claim 2 is the invention according to claim 1, wherein each of the heat storage materials is composed of a plurality of heat storage particles.

  According to a third aspect of the present invention, in the invention of the second aspect, the heat storage particles are prevented from oozing out to prevent the heat storage particles changed into a liquid phase from oozing out from the plate member. It is characterized by being processed.

  The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein a plurality of protrusions are formed on the one surface and the other surface of the plate member, respectively. Features.

  Invention of Claim 5 is a utilization method of the interior board material of Claim 1, Comprising: The said thermal storage material which has a phase change temperature suitable for time among the said one surface side and the said other surface side of the said plate member. Is selected, and the plate member is arranged so that the surface faces the room.

  According to the invention described in claim 1, since the heat storage materials contained in the plate member of the interior plate material on the one surface side and the other surface side thereof have different phase change temperatures, the phase change suitable for different times. By containing two types of heat storage materials having temperature on the plate member on one side and the other side, a single interior plate can be applied at different times. Accordingly, for example, the plate member contains a heat storage material having a melting point of 20 ° C. on one side of the plate member, and contains a heat storage material having a melting point of 30 ° C. on the other side, so that the one side faces the room in winter. The indoor cooling can be prevented by arranging the plate member in the summer, and the plate member can be arranged so that the other surface faces the room in the summer. Therefore, it is not necessary to form a dedicated interior plate material that contains a heat storage material having a phase change temperature suitable for each period of use of the interior plate material. It can be surely prevented.

  According to the invention described in claim 2, since the heat storage material is composed of a plurality of heat storage particles, the heat storage material can be more easily mixed into the material for forming the plate member of the interior plate material. it can.

  According to the invention described in claim 3, since each heat storage particle is subjected to a bleed-out preventing process for preventing each of the heat storage particles changed into a liquid phase from oozing out from the plate member, When each heat storage particle becomes a liquid by melting, the heat storage particles that have become liquid are prevented from oozing out of the plate member. Thereby, since the reduction | decrease of the thermal storage capacity | capacitance by the thermal storage particle oozing out from a board member is prevented, the fall of the thermal storage function and thermal radiation function of the thermal storage particle can be prevented reliably.

  According to the invention described in claim 3, since the plurality of protrusions are formed on one surface and the other surface of the plate member, the surface area of each surface of the plate member is equal to the amount of each protrusion formed. Each surface of the plate member is larger than that in the case where the surface is simply a flat surface. Thereby, since the area which contacts the air of the board member arrange | positioned indoors becomes large, the amount of heat absorbed by the thermal storage material in a board member from a room | chamber interior and the quantity of heat discharge | released indoors from a thermal storage material can be increased more. .

  According to invention of Claim 4, the surface of the side in which the thermal storage material which has a phase change temperature suitable for utilization time was selected among the one surface side and other surface side of the board member of an interior board material, and this surface By arranging the plate members so as to face the room, a single interior plate material can be applied at different times without forming a dedicated interior plate material as in the prior art every time the interior plate material is used.

  The present invention will be described with reference to the illustrated embodiments.

  FIG. 1 shows an example in which an interior board material according to the present invention is applied to a waist wall 10 provided in a room R of a building. As is well known in the art, the waist wall 10 is provided on the lower part 12a of each wall 12 defining the room R so as to cover the lower part from the inside of the room R, thereby preventing the lower part from being scratched or soiled. It is a wall to do.

  A waist wall 10 according to the present invention includes a plate member 11 attached to a wall 12. In the illustrated example, the plate member 11 is a particle board formed by heating and compressing a wood powder board formed by compressing and solidifying wood powder, or a small piece of wood coated with a synthetic resin adhesive. Etc. In the state shown in FIG. 1 in which the waist wall 10 is provided on the wall 12, the front surface 11a located inside the room R of the plate member 11 and the back surface 11b located on the opposite side to the front surface, as shown in FIG. A plurality of protrusions 13 are formed so as to protrude from the front surface 11a and the back surface 11b. In the example shown in the drawing, the protrusions 13 are formed so as to be equidistant from each other in the vertical direction of the plate member 11 and to extend along the width direction of the plate member 11. The formation positions of the protrusions 13 on the front surface 11a of the plate member 11 and the formation positions of the protrusions 13 on the back surface 11b are staggered.

  The plate member 11 contains a first heat storage material 14 for storing heat in the room R (indicated by white circles in FIG. 2). The first heat storage material 14 is composed of a plurality of granular first heat storage particles 14a made of, for example, sodium nitrate or hydrated salt. Each of the first heat storage particles 14a is arranged so as to be dispersed in the plate member 11 and each protrusion 13 on the surface 11a side of the plate member 11, and has a phase change temperature of 25 to 30 ° C.

  Further, the plate member 11 contains a second heat storage material 15 (indicated by black circles in FIG. 2). The second heat storage material 15 is composed of a plurality of granular second heat storage particles 15a made of sodium nitrate, a hydrate, or the like, like the first heat storage particles 14a. Each of the second heat storage particles 15a is disposed so as to be dispersed in the plate member 11 and each protrusion 13 on the back surface 11b side of the plate member 11, and has a phase change temperature of 20 to 25 ° C.

  That is, in the plate member 11 of the waist wall 10, the first heat storage particles 14a and the second heat storage particles 15a having different phase change temperatures are separately contained on the front surface 11a side and the back surface 11b side. Has been. In the present embodiment, the phase change temperature refers to a temperature at which each heat storage particle 14a, 15a undergoes a phase transition between a solid phase and a liquid phase, that is, a melting point or a freezing point.

  Further, each of the first and second heat storage particles 14 a and 15 a is subjected to a bleeding prevention process for preventing the heat storage particles changed into the liquid phase from bleeding from the plate member 11. In the illustrated example, the bleeding prevention process is performed by enclosing the first and second heat storage particles 14a and 15a in a microcapsule (not shown). Each of the microcapsules is made of a thermoplastic resin such as poly (meth) acrylate and polystyrene derivative.

  As shown in FIG. 3, a receiving member 17 for receiving the lower end 11 d of the plate member 11 and a plate member 11 are pressed against the wall 12 on the surface 12 a of the wall 12 to which the plate member 11 of the waist wall 10 is attached. The presser member 18 is provided. The receiving member 17 is fixed to the floor 19 of the room R. The back surface 12b of the wall 12 is provided with a pair of skeleton members 20 for securing the rigidity of the wall 12 at positions corresponding to the upper end 11c and the lower end 11d of the plate member 11, and the presser member 18 is a plate member. 11 is removably fixed to the skeleton member 20 corresponding to the upper end 11c of the member 11 through a wall 12 by a fastening member such as a nail and a screw (not shown). The receiving member 17 plays a role of a well-known baseboard for preventing the lower end 11d of the plate member 11 from being damaged, and the holding member 18 is a well-known headboard of the plate member 11. Have a role.

  When the waist wall 10 is installed on the wall 12, the pressing member 18 is removed from the wall 12, and the lower end 11 d of the plate member 11 is received in the member 17. Next, the pressing member 18 is put on the upper end 11 c of the plate member 11, and the pressing member 18 is attached to the wall 12 again in this state. Thus, the plate member 11 is attached to the wall 12 via the receiving member 17 and the pressing member 18, and the waist wall 10 is installed on the wall 12.

  When the room temperature is likely to rise as in summer, as shown in FIG. 3, the plate member 11 is arranged so that the first heat storage particles 14a are arranged indoors, that is, the surface 11a faces the room. Is attached to the wall 12. When the phase change temperature of each first heat storage particle 14a is 28 ° C., for example, when the room temperature rises to 28 ° C. or more, each first heat storage particle 14a changes from a solid phase to a liquid phase. At this time, since each first heat storage particle 14a is enclosed in the microcapsule as described above, each liquefied first heat storage particle 14a does not ooze out from the plate member 11. As the first heat storage particles 14a are melted, the indoor heat is absorbed by the respective heat storage particles, so that overheating of the room is prevented.

  On the other hand, when the room temperature is likely to fall as in winter, the plate member 11 is shown in FIG. 3 so that each second heat storage particle 15a is arranged indoors, that is, the back surface 11b faces the room. It is reversed from the state and attached to the wall 12. When the phase change temperature of each second heat storage particle 15a is, for example, 23 ° C., when the room temperature falls to 23 ° C. or less, each second heat storage particle 15a changes from the liquid phase to the solid phase. The solidification of the second heat storage particles 15a releases the heat stored in the heat storage particles into the room, thereby preventing the room from being cooled.

  The room temperature can be kept almost constant by the absorption of heat in the room and the release of heat into the room by the first and second heat storage particles 14a and 15a.

  As described above, the first and second heat storage particles 14a and 15a contained in the plate member 11 of the waist wall 10 on the front surface 11a side and the back surface 11b side have different phase change temperatures. The waist wall 10 can be applied at different times. Thereby, it is not necessary to form a dedicated interior plate material that contains a heat storage material having a phase change temperature suitable for each time period of use of the waist wall 10, so that the conventional manufacturing cost is reduced. Can be reliably prevented.

  As described above, since the first and second heat storage particles 14a and 15a are sealed in the microcapsules, the heat storage particles 14a and 15a are melted to become liquid. Thus, it is possible to reliably prevent the heat storage particles 14 a and 15 a that have become liquid from seeping out from the plate member 11. Thereby, since the reduction | decrease in the thermal storage capacity | capacitance by each heat storage particle 14a, 15a oozing out from the board member 11 is prevented, the fall of the heat storage function of each heat storage particle 14a, 15a and a thermal radiation function can be prevented reliably.

  Further, as described above, since the plurality of protrusions 13 are formed on the front surface 11a and the back surface 11b of the plate member 11, respectively, the front surface 11a and the back surface of the plate member 11 corresponding to the amount of each protrusion 13 formed. The surface area of 11b is larger than that when the surfaces 11a and 11b of the plate member 11 are simply flat surfaces. Thereby, since the area which contacts the air of the plate member 11 arrange | positioned indoors becomes large, the amount of heat absorbed by the 1st and 2nd each heat storage particle 14a, 15a in the plate member 11 from a room | chamber interior, and each said heat storage particle The amount of heat released into the room can be increased.

  In the present embodiment, the phase change temperatures of the first heat storage particles 14a and the second heat storage particles 15a are 25 to 30 ° C. and 20 to 25 ° C., respectively. The heat storage particles 14a and 15a can be formed of heat storage particles having a phase change temperature outside the above-described range, for example, depending on the location environment of the building.

  In the present embodiment, the bleeding prevention process applied to the first and second heat storage particles 14a and 15a encloses the first and second heat storage particles 14a and 15a in the microcapsules. However, instead of this, if it is possible to prevent the melted heat storage particles 14a and 15a from oozing out from the plate member 11, processing other than the processing using the microcapsules is performed. It can apply to each heat storage particle 14a, 15a.

  Furthermore, in the present embodiment, an example in which each of the heat storage materials 14 and 15 contained in the waist wall 10 is configured by a plurality of heat storage particles 14a and 15a has been shown, but instead of this, each of the heat storage materials 14 and 15 Can be made of, for example, a sheet-like or plate-like heat storage material. In this case, each heat storage material can be separately disposed in the plate member 11 on the front surface 11a side and the back surface 11b side.

  Further, in this embodiment, an example is shown in which the protrusions 13 are formed so as to be equally spaced from each other in the vertical direction of the plate member 11 of the waist wall 10 and to extend along the width direction of the plate member 11. However, instead of this, for example, the protrusions can be formed so as to be spaced apart from each other in the width direction of the plate member 11 and extend along the vertical direction of the plate member 11. Moreover, each protrusion 13 should just be formed so that the area of the surface 11a and the back surface 11b of the board member 11 may become larger than that in the case of a flat surface, The shape is limited to the shape shown in FIG. Not.

  Furthermore, in the present embodiment, an example is shown in which the formation positions of the protrusions 13 formed on the front surface 11a of the plate member 11 and the protrusions 13 formed on the back surface 11b are staggered. Instead of this, for example, each protrusion 13 can be formed at a position corresponding to the front surface 11 a and the back surface 11 b of the plate member 11.

  Further, in this embodiment, the example in which the interior board material according to the present invention is applied to the waist wall 10 provided on the wall 12 of the room R is shown, but instead of this, a wall board, a floor board, and a ceiling that define the room R are shown. The present invention can be applied to a board. In this case, the heat storage material which has phase change temperature suitable for the arrangement | positioning location of each board can be used for the heat storage material contained in a wall board, a floor board, and a ceiling board, for example.

It is a general-view figure of the room | chamber interior of the building in which the waist wall based on this invention was provided. It is a longitudinal section showing a waist wall concerning the present invention roughly. It is a longitudinal section showing the state where the waist wall concerning the present invention was attached to the wall.
