An outer wall is formed. For the base 61, for example, a member having the same shape as the steel frame 7 such as C-shaped steel is used. In addition, a ventilation fitting 65 is fixed to the steel frame 7 with a screw 64, and the exterior material 4 is fixed while being supported by the ventilation fitting 65. And between the exterior material 4 and the wall foundation 70 (steel frame 7), the ventilation layer 3 communicating with the outside of the building is formed as a heat insulation space, thereby improving the heat insulation of the outer wall structure. . Thus, by improving the heat insulation of the outer wall, it is possible to suppress the indoor temperature of the building from changing due to the outside air temperature or the like as much as possible. In the outer wall structure of FIG. 3, a waterproof sheet 62 is provided on the steel frame 7 in order to enhance waterproofness, and a drainer 63 is provided below the exterior material 4.

  However, the heat insulating performance that can be imparted to the outer wall is limited only by forming the heat insulating material 2 and the ventilation layer 3 as in the conventional heat insulating structure. For this reason, for example, in a region with a large temperature difference, the temperature environment in the building There was a problem that was easy to change. In particular, a steel frame such as the steel frame 7 used in a steel structure building has a small heat capacity. Therefore, even if the above external heat insulation method is applied, the heat insulation performance is limited, and it exceeds a certain level. It was difficult to impart thermal insulation to a building, and it was difficult to maintain a stable room temperature. From such a point of view, it is strongly desired to construct a heat insulating structure that increases the heat capacity of the entire structure and to make the temperature environment inside the building more comfortable.

  The present invention has been made in view of the above points, a panel material capable of imparting high heat insulation to a building and realizing a comfortable temperature environment indoors, and a heat insulating structure using the panel material. The purpose is to provide.

  The panel material according to the present invention is characterized in that a heat storage plate and a heat insulating material are integrally formed.

  Moreover, in said panel material, it is preferable to further provide the frame body which covers the outer periphery of the said board | plate material and the said heat insulating material.

  A heat insulating structure according to the present invention is a heat insulating structure of a building, and includes the panel material and an exterior material. The panel material includes the plate material on the indoor side of the building, and the heat insulating material is the building. The exterior material is disposed so as to face the heat insulating material, and a ventilation layer is formed between the panel material and the exterior material. It is characterized by.

  The panel material of the present invention has a high heat storage property and a heat insulation property because the plate material having a heat storage property and the heat insulating material are integrally formed. Therefore, by providing the panel material on the outer wall, roof, under floor, etc. of the building, it is possible to provide a comfortable indoor space for the building. For example, by providing the panel material on the outer wall of the building, the heat capacity of the entire outer wall structure can be increased by the heat storage action of the heat-storing plate material, and a comfortable temperature environment can be provided in the building interior. It becomes like this.

  In addition, the heat insulating structure of the present invention can provide high heat insulating properties by forming a heat insulating material and a ventilation layer, and further, since the above panel material is used, the heat capacity of the entire outer wall structure can be increased. It is possible to provide a comfortable temperature environment inside the building.

It is sectional drawing which shows a part of heat insulation structure of the outer wall. It is a perspective view which shows an example in the middle of construction of the heat insulation structure of this invention, and shows the state by which the panel material is attached to the wall base. It is sectional drawing which shows the conventional heat insulation structure. It is sectional drawing which shows the other conventional heat insulation structure.

  Hereinafter, modes for carrying out the present invention will be described.

  Fig.1 (a) is a perspective view which shows an example of embodiment of the panel material A of this invention. As shown in FIG. 1A, the panel material A is formed by integrally forming a plate material 1 and a heat insulating material 2 having heat storage properties. The panel material A is formed in a substantially rectangular plate shape in plan view. In the panel material A in the form of FIG. 1A, it is formed in a substantially rectangular shape in plan view.

  The plate material 1 having a heat storage property is formed in a substantially rectangular shape in a plan view and has a heat storage function. As such a plate material 1, it is possible to use a known heat storage board, for example, a member in which a microcapsule in which a heat storage material is encapsulated is coated or dispersed on a plate-like base material. It is done. The heat storage board can be obtained, for example, by mixing a solid medium such as a fiber serving as a base material and the microcapsule and performing a papermaking process. It is also possible to obtain a heat storage board by pulverizing the microcapsules and then entwining them with fibers in a dry manner to form a board.

  As a solid medium used as said base material, a cellulose fiber can be used, for example. Examples of the cellulose fiber in this case include those manufactured from plants such as pulp and waste paper, but the present invention is not limited thereto. In addition, examples of the solid medium serving as the base material include synthetic resins such as polyamide fibers such as nylon 6, nylon 66, and nylon 610, polyester fibers such as polyethylene terephthalate and polybutylene terephthalate, polyethylene, Examples thereof include polyolefin fibers such as polypropylene, acrylic fibers, polyparaphenylene fibers, vinylon fibers, polyurethane fibers, polyvinyl chloride fibers, acetate fibers, cupra fibers, and rayon fibers. The solid medium may be subjected to a process of unraveling (defibrating process) using a mixer or a disperser in advance.

  On the other hand, the microcapsules enclosing the heat storage material can be produced by a known production method, for example, Japanese Patent Laid-Open Nos. 62-1452, 62-45680, 62. -149334, JP-A-62-225241, JP-A-2-258052 and the like. Examples of the microcapsule membrane material include urea formalin resin, melamine formalin resin, polystyrene, polyacrylonitrile, polyamide, polyacrylamide, ethyl cellulose, polyurethane, and aminoplast resin. In addition, a synthetic resin or a natural resin using a coacervation method between gelatin and carboxymethyl cellulose or gum arabic may be used as a film material.

  Examples of the heat storage material included in the microcapsule include n-paraffins having 14 to 30 carbon atoms, inorganic eutectics, inorganic hydrates, fatty acids such as palmitic acid and myristic acid, benzene, and p. -Latent heat storage materials such as aromatic hydrocarbon compounds such as xylene, ester compounds such as isopropyl palmitate and butyl stearate, and alcohols such as stearyl alcohol are not limited to these in the present invention. The heat storage materials enumerated above may be used alone or in combination of two or more, and as long as the heat storage function is not hindered, known supercooling prevention materials, specific gravity Additives such as regulators and deterioration inhibitors may be mixed.

  The average particle diameter of the heat storage material-encapsulated microcapsules configured as described above is preferably 10 μm or less in order to suppress breakage due to physical pressure when the microcapsules are applied to or impregnated into the base material. More preferably, it is 5 μm or less. The average particle diameter here can be measured by, for example, a laser diffraction method. The average particle size of the microcapsules can be adjusted at the time of production. In coating or impregnating the microcapsules on the base material, appropriate additives such as a binder, a buffering agent, a dispersant, an antifoaming agent, a dye, a pigment, a flame retardant, and a fragrance may be used in combination.

  As described above, the plate material 1 can obtain a mixture of a solid medium as a base material and a microcapsule through a papermaking process, and this papermaking process can employ a conventional method. . Moreover, when obtaining the board | plate material 1, you may use together the multiple types of microcapsule from which the kind of heat storage material included is different. Note that the plate material 1 may contain glass wool and hollow particles as necessary as long as the heat storage property is not hindered.

  Although the thickness of the board | plate material 1 is not restrict | limited in particular, For example, it can be set to 5-25 mm, and if it exists in this range, the thermal storage property of the board | plate material 1 will become difficult to be impaired.

The heat insulating material 2 can be formed of a material conventionally used as a heat insulating material. For example, resin foam such as urethane foam, phenol foam, hard isocyanurate foam, styrene foam, glass wool, ceramic fiber, lock Examples include fiber aggregates such as wool, but are not limited thereto. The heat insulating material 2 can also be formed into a substantially rectangular plate shape in plan view, and the thickness and density thereof are not particularly limited. For example, the thickness may be 20 to 200 mm and the density may be 8 to 180 kg / m ^3. it can. Since the heat insulating material 2 is integrated with the plate material 1, the surface shape of the heat insulating material 2 is preferably the same shape as the surface shape of the plate material 1, and the dimensions are also preferably the same.

  In the panel material A of the present embodiment, the surfaces of the plate material 1 and the heat insulating material 2 are bonded and integrated with each other, but the method for integrating them is not particularly limited. For example, the plate material 1 and the heat insulating material 2 may be bonded and integrated with an adhesive, or may be combined and integrated with screws or nails. However, in the method of bonding with screws or nails, holes may be formed in the plate material 1 or the heat insulating material 2 and the performance may be lowered. If so, it is easy to manufacture the panel material A. The kind of the adhesive used for the adhesive integration is not particularly limited, and for example, a general-purpose adhesive used for adhering the heat insulating material can be used.

  The panel material A may further be provided with a frame 5. As shown in FIG. 1A, the frame 5 is provided along the outer periphery of the panel material A. In the embodiment of FIG. 1A, the frame 5 is provided so as to cover the outer end surface of the panel material A, that is, the outer end surfaces of the plate material 1 and the heat insulating material 2. In FIG. 1A, in order to easily explain the configuration of the panel material A, the outer end surface of one side end portion of the panel material A is illustrated with the frame body 5 omitted. The frame 5 may be provided so as to surround the entire outer periphery of the panel material A, or may be provided so as to surround a part of the outer periphery.

  For example, as shown in FIG. 1A, the frame 5 is composed of a pair of first frame members 51, 51 facing each other and a pair of second frame members 52, 52 facing each other. It is formed in a substantially square shape (frame shape). That is, the frame 5 is formed as a mold member having an opening surface in which a pair of first frame members 51 and 51 and a pair of second frame members 52 and 52 are assembled in a substantially rectangular shape. The opening portion of the frame 5 formed in this way is formed so as to match the surface shape of the panel material A. In the case where the panel material A is formed in a rectangular or square shape in plan view, the frame body 5 having a substantially rectangular cross section can be applied to the panel material A. The frame 5 may be formed by assembling each of the first frame members 51, 51 and the second frame members 52, 52 as separate members. The frame member 51 and the second frame member 52 may be integrally formed from the beginning.

  The material for forming the frame 5 is not particularly limited, but is preferably a material having low thermal conductivity. Therefore, it is preferable to form the frame 5 with a material such as wood or resin. The frame body 5 can be attached to the outer periphery of the panel material A using a well-known adhesive etc., for example.

  By attaching the frame 5 to the entire outer periphery of the panel material A, it is possible to easily prevent the panel material A from being damaged. As will be described later, if the frame body 5 is provided on the panel material A, the panel material A can be attached and fixed by driving a screw or the like into the frame body 5. Screw holes or the like are not formed in the heat insulating material 2, and it becomes easy to prevent a decrease in heat insulating performance and heat storage performance of the panel material A.

  The panel material A of this embodiment has high heat storage property and heat insulation property because the plate material 1 having heat storage property and the heat insulating material 2 are integrally formed. Therefore, it is possible to provide a comfortable indoor space for the building by providing the panel material A on the outer wall, roof, floor, etc. of the building.

  As shown in FIG. 1B, the panel material A can be used as a constituent member for forming an outer wall, for example.

  FIG.1 (b) shows an example of embodiment of the heat insulation structure B using the panel material A, Comprising: The cross section of the outer wall provided with the heat insulation structure B, ie, the said outer wall, was cut | disconnected in parallel with the horizontal surface. A part of the cut surface is shown. In the heat insulation structure B of this embodiment, the panel material A, the exterior material 4, and the ventilation layer 3 are provided. Further, a plurality of steel frames 7, 7,... Serving as a basic skeleton of the steel structure building are provided. In this heat insulation structure B, the panel material A, the ventilation layer 3 and the exterior material 4 are arranged in this order from the indoor side to the outdoor side of the building.

  The structure of the panel material A in the heat insulation structure B is the same as that of FIG.

  The exterior material 4 is not particularly limited as long as it is conventionally used as a wall material, and for example, a material formed in a substantially flat shape with a ceramic building board such as a fiber-reinforced cement board is used. The upper and lower ends of the exterior material 4 are formed with a real part at one end of the exterior material 4 and an actual receiving part at the other end so that the adjacent exterior materials 4 can be connected to each other vertically. Also good. The vertical direction here means the vertical direction when the outer wall of the building is directly viewed. In addition, a pattern such as an uneven pattern may be formed on the surface of the exterior material 4. In addition, since FIG.1 (b) is the heat insulation structure B of an outer wall, although the wall material was illustrated here as the exterior material 4, if the heat insulation structure B is applied to a roof etc., for example, the exterior material 4 A known roofing material is used.

  As the steel frame 7, steel materials conventionally used in steel-framed buildings such as lip groove steel, C steel, and H steel can be used. Such a steel frame 7 is formed in a column shape long in one direction.

  In the heat insulation structure B of the above embodiment, the plurality of steel frames 7, 7,... Are mounted and fixed in a row on the base 61 with a predetermined interval so that each is substantially parallel to each other. It is installed side by side. As the base 61, for example, a steel material such as C-shaped steel described in FIG. 3 is used. As described above, by providing the steel frames 7 in a line, a wall base 70 made up of a plurality of steel frames 7, 7,... Is formed. As described above, the steel frame 7 is installed on the base 61 with a predetermined interval. However, as shown in FIG. 1B, the steel frames 7 and 7 are provided so as to be adjacent to each other. It has been. In addition, the outdoor side as used in this specification means the outer side of the building which has the heat insulation structure B, and the indoor side means the inner side of a building. In FIG. 1B, the surface of the steel frame 7 on the outdoor side is denoted by reference numeral “7a”.

  The panel material A is provided on the outdoor side of the wall base 70 (steel frame 7) so as to bridge the outdoor side surface 7a of each of the plurality of steel frames 7, 7,. . And the panel material A is arrange | positioned so that the surface by the side of the board | plate material 1 of the panel material A may face the indoor side (wall base | substrate 70 side), and the surface by the side of the heat insulating material 2 of the panel material A may face the outdoor side. In the present embodiment, as shown in FIG. 1B, the panel material A is disposed so that the second frame member 52 is substantially parallel to and opposed to the longitudinal direction of the steel frame 7. The panel material A is attached to the steel frame 7 with a fixture 8 such as a screw or a nail. The fixture 8 is driven into the first frame member 51 and the second frame member 52, for example.

  On the surface of the panel material A provided as described above on the heat insulating material 2 side, a plurality of trunk edges 85 are provided substantially parallel to each other with a predetermined interval. The trunk edge 85 is formed in a columnar shape having a substantially rectangular cross section, and is provided so that the longitudinal direction of the trunk edge 85 is parallel to the height direction of the outer wall. The trunk edge 85 is disposed at an arbitrary position. For example, as shown in FIG. 1B, the trunk edge 85 is provided at a position facing the steel frame 7 with the panel material A interposed therebetween. The trunk edge 85 is attached and fixed by the fixture 8 in the same manner as the method for attaching the panel material A.

  The exterior material 4 is provided so as to bridge the plurality of trunk edges 85 provided as described above. Therefore, the exterior material 4 is disposed at a position facing the surface of the panel material A on the heat insulating material 2 side, that is, the surface of the panel material A on the outdoor side. The exterior material 4 is attached and fixed to the trunk edge 85 using a fixing tool 8 such as a screw or a nail.

  In the heat insulation structure B of the present embodiment, the plurality of trunk edges 85, 85,... Are interposed between the exterior material 4 and the panel material A, so that the trunk edges 85 are both provided. It will serve as a spacer between. Therefore, a space is formed in a portion other than the trunk edge 85 between the exterior material 4 and the panel material A, and this space is formed as the ventilation layer 3 of the heat insulating structure B. The ventilation layer 3 may be formed so as to communicate with a space outside the building.

  Although not shown in FIG. 1B, a wall material such as a gypsum boat and an interior material are usually provided on the indoor side (the side opposite to the panel material A side) of the wall base 70.

  In the heat insulation structure B of the present embodiment, the ventilation layer 3 is formed by providing the trunk edge 85 as described above, but of course, even if the ventilation layer 3 is formed by a method other than this. Good. For example, although not shown, a known mounting bracket capable of forming the ventilation layer 3, that is, a so-called ventilation bracket may be used. As such a metal fitting, for example, the wall material fastener disclosed in Japanese Patent Application Laid-Open No. 2009-161955 (see FIG. 2 of the publication) or the ventilation metal fitting 65 described in FIG. 3 is used. However, it is not limited to these. In the case of using a ventilation fitting or the like, the ventilation fitting itself is interposed between the exterior material 4 and the heat insulating material 2, whereby the ventilation layer 3 is formed. The mounting method, the arrangement position, the arrangement number, and the like of the wall material fastener and the ventilation fitting 65 are not particularly limited, and a conventionally used method or aspect may be adopted. Moreover, you may use the trunk edge 85 and the said attachment metal fitting together.

  In the heat insulation structure B of this embodiment, since the panel material A has the plate material 1 having heat storage properties, the heat capacity of the whole heat insulation structure B can be increased, and the temperature change on the indoor side of the building is less likely to occur. be able to. For example, even if heat from an air conditioner or the like from the inside of a building is transmitted to the wall base 70 and reaches the panel material A, the heat is stored by the plate material 1 having heat storage properties, so that heat flows out of the building. Is suppressed. Therefore, it becomes easy to maintain the temperature in the building room, and a comfortable temperature environment can be provided indoors. Moreover, since the board | plate material 1 has heat storage property, heat will be stored in the board | plate material 1 by sufficient solar radiation in the daytime, and this can also moderate the indoor cooling at night.

  Moreover, in the heat insulation structure B, since the heat insulation can be enhanced by the heat insulating material 2, it becomes easy to prevent the heat stored in the plate material 1 from escaping to the outside of the building. And the heat insulation of the heat insulation structure B can be improved more also by the ventilation layer 3 being formed as a heat insulation space so that the outdoor side of the heat insulating material 2 may be faced. In addition, the presence of such a ventilation layer 3 can prevent the heat insulating material 2 and the exterior material 4 from being in close contact with each other, so that the occurrence of condensation between the heat insulating material 2 and the exterior material 4 is easily suppressed. Therefore, the heat insulating material 2 and the exterior material 4 are hardly damaged or deteriorated, and the durability of the entire outer wall can be improved.

  Therefore, if the heat insulation structure B provided with the panel material A is applied to an outer wall or the like, the outer wall or the like has both excellent heat insulating properties and heat storage properties.

  Here, in order to further enhance the heat storage effect of the heat insulating structure B, for example, it is preferable that the melting point of the heat storage material used to form the plate 1 is in the range of 10 to 35 ° C. When the plate material 1 including the heat storage material in the melting point range is used for the heat insulation structure B, the solid heat storage material is melted into a liquid by heat from sunlight in the daytime or heat from an indoor air conditioner, etc. It becomes easy to change into solid again because it is cooled. Therefore, heat absorption occurs due to melting of the heat storage material during the daytime, and heat dissipation occurs due to the solidification of the heat storage material during the nighttime. Thereby, the fall of the indoor temperature at night can be suppressed.

  The heat insulation structure B of the embodiment of FIG. 1B can be formed by the following procedure, for example.

  First, as shown in FIG. 2, a base 61 is provided on a foundation 60 in advance, and a plurality of steel frames 7, 7,... 70 is formed. Subsequently, the panel material A is attached so that the outdoor side surface 7a of each of the plurality of steel frames 7, 7,. When attaching the panel material A, as shown in FIG. 2, the panel material A is arranged on the outdoor side of the wall base 70, and the panel material 1 of the panel material A is attached so as to face the wall base 70 side. In FIG. 2, in order to clearly represent the layer configuration of the panel material A and the orientation of the panel material A, a part of the panel material A is broken and illustrated.

  Moreover, when providing the panel material A, if it arrange | positions so that the at least one side edge part of the panel material A may follow along with the steel frame 7, it will be easy to position the panel material A, and the state of attachment will become stable easily. . In FIG. 2, the panel material A is arranged so that the second frame material 52 extends along the steel frame 7.

  The panel material A can be attached to the steel frame 7 using the fixture 8 (illustration of the fixture 8 is abbreviate | omitted in FIG. 2). As described above, it is preferable that the fixture 8 is driven into the frame body 5 from the viewpoint of making it difficult to lower the heat insulating property and heat storage property of the panel material A. If the fixture 8 is driven into the frame 5 and the tip of the fixture 8 is driven into the steel frame 7, the panel material A is attached and fixed to the wall base 70. The panel material A can be provided so as to reach substantially the entire surface of the outer wall by sequentially attaching a plurality of panel materials A while adjoining them in the vertical and horizontal directions.

  Next, a plurality of trunk edges 85, 85,... Are provided on the surface of the panel material A on the heat insulating material 2 side. In this case, the trunk edge 85 can be provided at a position facing the steel frame 7 across the panel material A. Therefore, although the space | interval between the adjacent trunk edges 85 and 85 can be made substantially equivalent to the arrangement | positioning space | interval of the adjacent steel frames 7 and 7, of course, it may be narrower than that or may be wide. The trunk edge 85 can be attached to the panel material A by the fixture 8. In this case, the fixture 8 may be provided from the outdoor side of the trunk edge 85 so that the tip of the fixture 8 is driven into the frame body 5.

  Then, the exterior material 4 is attached so that several trunk edges 85, 85, ... may be bridged. Even in the exterior material 4, a plurality of sheets can be prepared and sequentially provided while adjoining them in the vertical direction and the horizontal direction. As described above, when a real part is formed at one end of the exterior material 4 and an actual receiving part is formed at the other end, the actual part of one exterior material 4 and the other exterior material among the adjacent exterior materials 4. The four actual receiving portions may be connected to each other by fitting. Further, a sealing agent or the like may be provided between the adjacent exterior materials 4 and 4. The exterior material 4 can be fixed using screws, nails, or the like. For example, the exterior material 4 may be driven from the surface of the exterior material 4 toward the trunk edge 85. Or you may attach the exterior | packing material 4 using the ventilation metal fitting etc. which were mentioned above.

  By constructing according to the procedure as described above, the heat insulating structure B can be constructed, and the outer wall having the heat insulating structure B is formed. In the heat insulation structure B of the present embodiment, the panel material A is directly provided on the steel frame 7. However, the panel material A is provided by interposing a material such as a waterproof sheet between the panel material A and the steel frame 7 to improve waterproofness. May be applied. Further, the structures of the side wall, the upper edge, the lower edge, and the like of the outer wall are not particularly limited, and can be formed to have a conventionally known structure.
