Description

  The present invention relates to a resin board for forming an air-permeable layer between an attic field board and a heat insulating material or between a wall and a heat insulating material, and a method of using the resin board.

  2. Description of the Related Art Conventionally, in a house, in order to suppress a temperature rise in a living room, a construction has been performed in which a heat insulating material is disposed on the side of the roof of the athletic field board. The heat insulating material is generally constructed by a method of spreading glass wool or rock wool, a method of using foamed urethane formed in a panel shape at a factory, a method of forming foamed urethane by spraying it at a construction site, or the like. In order to further suppress the temperature rise in the room, it is conceivable to form a ventilation layer between the base plate and the heat insulating material to ventilate the air or to shield the radiant heat from the roof.

  Therefore, a heat insulating material made of urethane and an aluminum foil provided on the space through the space is known (for example, see Non-Patent Document 1). This heat insulating material is fitted between rafters with the aluminum foil side facing the base plate. The space between the urethane and the aluminum foil becomes a ventilation layer, and the aluminum foil shields the radiant heat from the roof.

  Further, there is known a ventilation member formed with unevenness using a nonwoven fabric of PET (polyethylene terephthalate) fiber, which is used for providing a ventilation layer between a field board and a heat insulating material (see, for example, Non-Patent Document 2). This ventilation member is fitted between the rafters with the uneven side facing the base plate, and a heat insulating material (formed by foaming urethane in a panel shape or by blowing urethane foam) from below. Provided. When the uneven | corrugated front-end | tip of the ventilation member contacts a field plate, a space is ensured between a field plate and a ventilation member, and a ventilation layer is formed between a field plate and a heat insulating material.

  Further, a ventilation member in which both ends of a corrugated cardboard are bent is known (for example, see Non-Patent Document 3). The ventilation member is fitted between the rafters with the front end side of the bent portions at both ends thereof facing the base plate, and a heat insulating material is provided from the lower side thereof. When the tip of the bent portion of the ventilation member contacts the field plate, a space is secured between the field plate and the ventilation member, and a ventilation layer is formed between the field plate and the heat insulating material. The ventilation member has aluminum deposited on the surface of the base plate, and the aluminum shields radiant heat from the roof.

  Further, a ventilation member is known in which both ends of a polypropylene molded plate are bent (see, for example, Non-Patent Document 4). The ventilation member is fitted between the rafters with the front end side of the bent portions at both ends thereof facing the base plate, and a heat insulating material is provided from the lower side thereof. When the tip of the bent portion of the ventilation member contacts the field plate, a space is secured between the field plate and the ventilation member, and a ventilation layer is formed between the field plate and the heat insulating material. The ventilation member is provided with a heat shielding film on the surface of the base plate, and the heat shielding film shields radiant heat from the roof.

  Moreover, the face material used in order to form a ventilation layer between a field board and a heat insulating material or between an outer wall and a heat insulating material is known (for example, refer patent document 1). This face material is in the form of a sheet of softness, flexibility or flexibility, such as a laminated paper face material obtained by laminating a plastic film on a paper material, a film face material such as a polyethylene film or a polypropylene film, and a polyester nonwoven fabric. Examples thereof include a fiber sheet material, a sheet material obtained by coating or laminating a synthetic resin porous film on a nonwoven fabric, and an aluminum foil laminated polyethylene sheet material.

Japanese Patent No. 4919449

  However, in the heat insulating material described in Non-Patent Document 1 described above, since the aluminum foil does not have moisture permeability, condensation occurs on urethane, and the urethane deteriorates due to moisture. Moreover, there is a possibility that the aluminum foil is torn during construction, and when the aluminum foil is torn, moisture such as rainwater is applied to the urethane, and the urethane deteriorates. Moreover, since the ventilation member described in Non-Patent Document 2 is made of a nonwoven fabric of PET fiber, it does not have waterproofness. For this reason, moisture such as rainwater is applied to the heat insulating material, and the heat insulating material is deteriorated by the water. Further, since the ventilation member described in Non-Patent Document 3 is made of cardboard, it absorbs moisture in the air and causes mold generation and deterioration. Moreover, since the ventilation member described in Non-Patent Document 4 is made of a polypropylene molded plate, it does not have moisture permeability. For this reason, condensation forms on the ventilation member, and the ventilation member deteriorates due to the moisture.

  Further, in the heat insulating material described in Non-Patent Document 1, an operation of fitting the heat insulating material between the rafters is necessary, and in the air-permeable member described in Non-Patent Documents 2 to 4, the ventilation member is used. The work of fitting between rafters is necessary, and in both cases, the workability of construction is poor. Further, in the ventilation member described in Non-Patent Document 4, when the heat insulating material is formed by blowing urethane foam, since the ventilation member is made of resin, the ventilation member is bent by the foaming heat of urethane foam. There is a risk that the air-permeable layer cannot be secured. Further, in the face material described in Patent Document 1, when the heat insulating material is formed by spraying general foamed urethane, the face material is a soft or flexible or flexible sheet-like material, and therefore foam. There is a possibility that the face material is curved by the foaming heat of urethane and the air-permeable layer cannot be secured. For this reason, in order to ensure a ventilation layer reliably, special foaming urethane with little foaming heat must be used.

  The present invention has been made in order to solve the above-described problems, and has a heat shielding property, a moisture permeable property, and a waterproof property, and can form a ventilation structure of a roof or a wall by an easy construction work. The purpose is to provide a board and its usage.

  In order to achieve the above object, the resin board of the present invention is formed by laminating a heat-insulating and moisture-permeable waterproof sheet and a mesh-like resin sheet in layers, and is used for a ventilation structure.

  The resin board preferably has aluminum deposited or laminated printed on the surface of the heat-insulating and moisture-permeable waterproof sheet.

  Moreover, it is preferable that the resin board has a two-layer structure of at least a synthetic resin molded film and a nonwoven fabric.

  Moreover, it is preferable that the resin board has a three-layer structure including a non-woven fabric, a synthetic resin molded film, and a non-woven fabric.

  Further, the method of using the resin board, wherein the resin board is provided with a rafter on the lower surface of the attic field board, thereby forming a roof ventilation layer between the field board and the resin board. The resin board is fixed to the bottom surface of the rafter with the heat-insulating and moisture-permeable waterproof sheet side facing the base plate, and urethane foam is provided as a heat insulating material on the resin sheet side.

  Further, in the method of using a resin board, the resin board is fixed to an outer surface of a column, and an exterior material is provided on the outer surface of the resin board with a trunk edge interposed therebetween, whereby the resin board and the The resin board is fixed to the outer surface of the column with the heat insulating moisture permeable waterproof sheet side facing the exterior material, and urethane foam is used as a heat insulating material on the resin sheet side. It is provided.

  According to the present invention, a roof ventilation structure can be formed between the resin board and the field board by an easy construction work of fixing the resin board to the lower surface of the rafters of the attic. Moreover, a wall ventilation structure can be formed between the resin board and the exterior material by an easy construction work of fixing the resin board to the outer surface of the pillar. Thereby, construction workability | operativity can be improved. In addition, the resin board is lightweight because it is made by adhering a heat-insulating and moisture-permeable waterproof sheet and a mesh-like resin sheet. Thereby, construction workability | operativity can be improved further. Furthermore, since the resin board has a heat shielding property, when used as a roof ventilation structure, it can shield the radiant heat from the roof to suppress the temperature rise in the room, and when used as a wall ventilation structure, The radiant heat from the exterior material can be shielded to suppress the temperature rise in the room. In addition, since the resin board has moisture permeability, it prevents condensation on the resin board, rafters, pillars, studs and trunk edges, and prevents deterioration of the resin boards, rafters, pillars, studs and trunk edges. Can do. In addition, since the resin board is waterproof, it prevents moisture from being applied to the heat insulating material, rafters, pillars, and studs provided below or inside the resin board, and the heat insulating material, rafters, pillars, and studs. Can be prevented. In addition, since the resin sheet has a mesh shape, when providing a general urethane foam as a heat insulating material, fix the heat-insulating and moisture-permeable waterproof sheet side to the rafters or pillars toward the field board or exterior material, Even if urethane foam is sprayed on the resin sheet side, the resin board is not deformed by the foaming heat of the urethane foam. Therefore, it is possible to reliably form a ventilation layer between the resin board and the base plate or between the resin board and the exterior material. Moreover, it is not necessary to use special foamed urethane with little foaming heat, and general foamed urethane can be used.

  Hereinafter, a roof ventilation structure and a wall ventilation structure using a resin board according to an embodiment of the present invention will be described with reference to the drawings. 1 and 2 show a schematic configuration of a house in which a roof ventilation structure is constructed using a resin board, and FIG. 3 shows a configuration of the resin board, together with enlarged views of the A part and the B part. Yes. The resin board 1 is used to form a ventilation layer 5 between the base plate 3 on the back of the roof 2 and the heat insulating material 4. The field board 3 is provided on the rafter 6, and the roof 2 is attached to the pier 7 on the field board 3. The resin board 1 is a sheet-like member and has heat shielding properties, moisture permeability, and waterproof properties. The resin board 1 is provided below the rafter 6. Thereby, the ventilation layer 5 is formed between the field board 3 and the resin board 1. A heat insulating material 4 is provided on the lower side of the resin board 1. Thereby, the ventilation layer 5 is formed between the base plate 3 and the heat insulating material 4.

  As shown in FIG. 3, the resin board 1 is formed of a sheet member in which a heat-insulating and moisture-permeable waterproof sheet 11 and a mesh-like resin sheet 12 are attached in layers. The heat-insulating and moisture-permeable waterproof sheet 11 includes a first layer 11a made of a synthetic resin fiber nonwoven fabric, a second layer 11b made of a synthetic resin molded film having moisture permeability and waterproof properties, and a third layer made of a synthetic resin fiber nonwoven fabric. It has a three-layer structure composed of the layer 11c. In this embodiment, the 1st layer 11a and the 3rd layer 11c consist of a nonwoven fabric of PET (polyethylene terephthalate) resin fiber, and the 2nd layer 11b consists of a film of polyethylene resin. Further, the heat-insulating and moisture-permeable waterproof sheet 11 has aluminum 11d deposited or laminated printed on the surface thereof, that is, the surface of the first layer 11a.

  The heat-insulating and moisture-permeable waterproof sheet 11 has moisture permeability by the fact that the first layer 11a and the third layer 11c are made of non-woven fabric, and that the polyethylene constituting the second layer 11b has moisture permeability. Moreover, the heat-insulating and moisture-permeable waterproof sheet 11 has a waterproof property because the second layer 11b is made of a film. Further, the heat-insulating and moisture-permeable waterproof sheet 11 has a heat-shielding property by depositing or laminating aluminum 11d on the surface.

  The resin sheet 12 is formed by forming a synthetic resin into a mesh shape, that is, having a large number of through holes 12a, and is attached to the back surface of the heat-insulating and moisture-permeable waterproof sheet 11, that is, the surface of the third layer 11c. It is attached. The resin sheet 12 is configured to withstand the heat of foaming of urethane foam when the heat insulating material 4 is formed by spraying general foamed urethane by molding the synthetic resin into a mesh shape. The resin sheet 12 is preferably made of PP (polypropylene) or PET (polyethylene terephthalate) having a relatively high heat resistance temperature. In the present embodiment, the resin sheet 12 is made of PP.

  The heat-insulating and moisture-permeable waterproof sheet 11 and the resin sheet 12 are attached to each other so as to have moisture permeability. Specifically, an adhesive is sprayed on the back surface (third layer 11 c) of the heat-insulating and moisture-permeable waterproof sheet 11 or the surface of the resin sheet 12 to adhere the heat-insulating and moisture-permeable waterproof sheet 11 and the resin sheet 12. The resin board 1 has moisture permeability by adhering the heat-permeable moisture-permeable waterproof sheet 11 having moisture permeability and the mesh-like resin sheet 12 in this manner. Further, the resin board 1 is waterproof due to the waterproof property of the heat-insulating and moisture-permeable waterproof sheet 11. Further, the resin board 1 has a heat shielding property due to the heat shielding property of the heat-insulating and moisture-permeable waterproof sheet 11. The thickness of the heat-insulating and moisture-permeable waterproof sheet 11 is preferably 0.1 mm to 2.0 mm, and the thickness of the resin sheet 12 is preferably about 0.1 mm to 2.0 mm. In this embodiment, the thickness of the heat-insulating and moisture-permeable waterproof sheet 11 is 0.3 mm, and the thickness of the resin sheet 12 is 1.0 mm. The resin board 1 is manufactured as a long object, and is used after being cut into appropriate dimensions.

  FIG. 4 shows a method for constructing a roof ventilation structure using the resin board 1, and FIGS. 5 and 6 show a state where the resin board is constructed. Construction of the roof ventilation structure is performed by fixing one surface of the resin board 1 to the lower surface of the rafter 6 and spraying foamed urethane 20 serving as the heat insulating material 4. That is, first, as shown in FIGS. 5 and 6, each resin board 1 is fixed to the lower surface of the rafter 6 using a plurality of resin boards 1 so as to cover the entire surface of the field board 3. Each resin board 1 uses what was cut beforehand according to the space | interval of the rafters 6, or what was cut on-site, the heat-insulation moisture-permeable waterproof sheet 11 side is turned to the field board 3, and it is between several rafters 6. It is straddled and fixed to the lower surface of the rafter 6. In the present embodiment, the three rafters 6 are straddled and fixed to the lower surface of the rafter 6. In the present embodiment, the resin board 1 is fixed to the lower surface of the rafter 6 by tacking at a plurality of locations. Thereby, the ventilation layer 5 is formed between the resin board 1 and the base plate 3. Then, the heat insulating material 4 is formed by spraying urethane foam 20 on the resin sheet 12 side of the resin board 1. The urethane foam 20 is generally used to form the heat insulating material 4. At this time, since the resin sheet 12 has a mesh shape and has a large number of through holes 12a, the resin board 1 is not curved by the heat of foaming of the foamed urethane 20. This is because even if the resin sheet 12 is softened and deformed by the foaming heat of the urethane foam 20, the deformation is a deformation that changes the shape of the through hole 12 a of the resin sheet 12, and the deformation of the resin board 1 as a whole is suppressed. Because. Therefore, since the resin board 1 is not bent by the heat of foaming of the urethane foam 20, the ventilation layer 5 between the resin board 1 and the field board 3 is maintained, and the ventilation layer 5 is formed between the field board 3 and the heat insulating material 4. It exists. Thereby, a roof ventilation structure is constructed and it will be in the state shown in the said FIG. 1, FIG.

  7 and 8 show a schematic configuration of a wall ventilation structure using the resin board 1. The resin board 1 is used to form a ventilation layer 5 between an exterior material 31 that is an outer wall of a house and a heat insulating material 4. The resin board 1 has the same configuration as that shown in FIG. The resin board 1 is provided between the pillar 32 and the intermediate pillar 33 and the trunk edge 34. Thereby, the ventilation layer 5 is formed between the exterior material 31 and the resin board 1. A heat insulating material 4 is provided on the indoor side of the resin board 1. Thereby, the ventilation layer 5 is formed between the exterior material 31 and the heat insulating material 4.

  FIG. 9 shows a construction method of the wall ventilation structure using the resin board 1. After constructing the pillars 32 and the intermediate pillars 33, first, the resin board 1 is fixed to the outer surfaces of the pillars 32 and the intermediate pillars 33 from the outdoor side. The resin board 1 is fixed to the outer surfaces of the columns 32 and 33 with the resin sheet 12 side facing the columns 32 and the columns 33. A plurality of pillars 32 and interstices 33 are alternately constructed. In this embodiment, the resin board 1 is a long one, and the pillars 32 and the struts 33 are straddled across the plurality of pillars 32 and the intermediary pillars 33. It fixes to the outer surface of the stud 33. Further, in the present embodiment, fixing of the resin board 1 to the outer surfaces of the pillars 32 and the intermediate pillars 33 is performed by fastening the resin board 1 to the pillars 32 and the intermediate pillars 33 with the tucker 35. Subsequently, the trunk edge 34 is constructed from the outdoor side. The trunk edge 34 is constructed by fastening the trunk edge 34 to the pillars 32 and the intermediate pillars 33 via the resin board 1 with, for example, nails or wood screws. Subsequently, the exterior material 31 is constructed from the outdoor side. The exterior material 31 is constructed by fastening the exterior material 31 to the trunk edge 34 with, for example, a fastening bracket. Thereby, the ventilation layer 5 is formed between the resin board 1 and the exterior material 31. The resin board 1 is in a state of being fixed to the outer surfaces of the columns 32 and the intermediate columns 33 with the heat-insulating and moisture-permeable waterproof sheet 11 side facing the exterior material 31. Subsequently, the heat insulating material 4 is formed by blowing urethane foam 20 from the indoor side to the resin sheet 12 side of the resin board 1. At this time, since the resin sheet 12 has a mesh shape and has a large number of through holes 12a, the resin board 1 is not bent by the foaming heat of the urethane foam 20, and the resin board 1 and the exterior material 31 The ventilation layer 5 is maintained, and the ventilation layer 5 exists between the exterior material 31 and the heat insulating material 4. Thereby, a wall ventilation structure is constructed and it will be in the state shown in the said FIG. 7, FIG.

  According to the resin board 1 of the present embodiment, the ventilation layer 5 is formed between the resin board 1 and the field board 3 by an easy construction work of fixing the resin board 1 to the lower surface of the rafter 6 behind the roof 2. be able to. Further, the ventilation layer 5 can be formed between the resin board 1 and the exterior material 31 by an easy construction work of fixing the resin board 1 to the outer surface of the column 32. Thereby, construction workability | operativity can be improved. In addition, the resin board 1 is lightweight because the heat-insulating and moisture-permeable waterproof sheet 11 and the resin sheet 12 are attached. Thereby, construction workability | operativity can be improved further. Furthermore, since the resin board 1 has a heat shielding property, when used as a roof ventilation structure, the radiant heat from the roof 2 can be shielded to suppress the temperature rise in the room, and the resin board 1 is used as a wall ventilation structure. At this time, the radiant heat from the exterior material 31 can be shielded to suppress the temperature rise in the living room. Moreover, since the resin board 1 has moisture permeability, it prevents the resin board 1, the rafters 6, the pillars 32, the intermediary pillars 33, and the trunk edges 34 from condensing, so that the resin board 1, the rafters 6, the pillars 32, Deterioration of the studs 33 and the trunk edge 34 can be prevented. Further, since the resin board 1 is waterproof, it prevents the moisture from being applied to the heat insulating material 4, the rafters 6, the pillars 32, and the intermediate pillars 33 provided below or inside the resin board 1. 4. Deterioration of the rafters 6, the pillars 32, and the studs 33 can be prevented.

  Furthermore, since the resin sheet 12 has a mesh shape, even when the heat insulating material 4 is formed by spraying a general urethane foam 20, the resin board 1 is not deformed by the heat of foaming of the urethane foam 20, The ventilation layer 5 can be formed reliably. Therefore, it is not necessary to use a special foamed urethane with little foaming heat, and a general foamed urethane can be used. Further, by depositing or laminating aluminum 11d on the surface of the heat-insulating and moisture-permeable waterproof sheet 11, the resin board 1 can be easily provided with heat-insulating properties. In addition, the heat-insulating and moisture-permeable waterproof sheet 11 has a three-layer structure including the first layer 11a, the second layer 11b, and the third layer 11c, so that the resin board 1 has a moisture permeability and a waterproof property while being resin. The resistance against the pulling force of the board 1 can be increased, and damage such as the resin board 1 being torn can be prevented. Moreover, since the resin board 1 has the heat-insulating and moisture-permeable waterproof sheet 11 and the resin sheet 12 attached, the structure is simple and the manufacturing cost can be reduced.

  FIG. 10 shows a modified example of the resin board, and also shows enlarged views of the C part and the D part. The resin board 1 is different from the above embodiment in the configuration of the heat-insulating and moisture-permeable waterproof sheet 11. In this resin board 1, the heat-insulating and moisture-permeable waterproof sheet 11 is composed of a first layer 11a made of a synthetic resin molded film having moisture permeability and waterproof properties, and a second layer 11b made of a synthetic resin fiber non-woven fabric. An aluminum 11d is vapor-deposited or laminated printed on the surface of the first layer 11a (synthetic resin molding film). In the present embodiment, the first layer 11a is made of a polyethylene resin film, and the second layer 11b is made of a nonwoven fabric of PET (polyethylene terephthalate) resin fibers.
