例如，如圖5(a)所示，提案有用以防止冬季型結露之外壁構造a。該外壁構造a包含：外飾材料b；隔熱材料d，其與該外飾材料b之間隔著流動空氣s之通氣層c而配置；內飾材料e，其配置於該隔熱材料d之室內側i；透濕防水層h，其配置於隔熱材料d之面向通氣層c之外表面；及防濕層g，其配置於內飾材料e與隔熱材料d之間。該等構成構件除防濕層g以外，均具有透濕性。For example, as shown in FIG. 5(a), a proposal is proposed to prevent the winter-type condensation outer wall structure a. The outer wall structure a includes: an exterior material b; a heat insulating material d disposed between the exterior material b and a ventilation layer c of the flowing air s; and an interior material e disposed on the heat insulating material d The indoor side i; the moisture-permeable waterproof layer h is disposed on the outer surface of the heat insulating material d facing the air permeable layer c; and the moisture-proof layer g is disposed between the interior material e and the heat insulating material d. These constituent members have moisture permeability in addition to the moisture-proof layer g.
此種外壁構造a可有效地防止冬季之壁內結露。即，藉由在室內側i開放暖氣等而使室內側i成為高溫高濕，且室外側o成為低溫低濕，故雖濕氣m之氣流f1自室內側i朝向室外側，藉由防濕層g而防止濕氣m向壁內流入。又，即使濕氣m流入壁內，其主要部分亦會藉由流過通氣層c之空氣s而向外部排出，從而可有效地防止壁內結露。作為相關之習知技術而有如下者。Such an outer wall structure a can effectively prevent condensation in the wall in winter. In other words, the indoor side i is made to be high-temperature and high-humidity by opening the heating or the like on the indoor side i, and the outdoor side o is low-temperature and low-humidity. Therefore, the airflow f1 of the moisture m is directed from the indoor side i toward the outdoor side, and is protected from moisture. Layer g prevents moisture m from flowing into the wall.

即，如圖5(b)所示，於炎熱地區等之夏季，外部空氣本身含有大量濕氣m，並且於室內側i開放冷氣，故室外側o成為高溫高濕，且室內側i成為低溫低濕。因此，濕氣m之氣流f2自室外側o朝向室內側i，從而存在該濕氣m於防濕層g之室外側o之表面冷卻而易於結露之問題。That is, as shown in FIG. 5(b), in the summer in a hot area or the like, the outside air itself contains a large amount of moisture m, and the cold air is opened on the indoor side i, so that the outdoor side o becomes high temperature and high humidity, and the indoor side i becomes low temperature. Low humidity. Therefore, the airflow f2 of the moisture m is directed from the outdoor side o toward the indoor side i, and there is a problem that the moisture m is cooled on the surface of the outdoor side o of the moisture-proof layer g to be easily dew condensation.

本發明之用以防止夏季型結露之外壁構造包含：外飾材料；隔熱材料，其與該外飾材料之間隔著流動空氣之通氣層而配置；內飾材料，其配置於該隔熱材料之室內側；及內飾修飾材料，其貼附於該內飾材料之室內側。The outer wall structure for preventing summer dew condensation of the present invention comprises: an exterior material; a heat insulating material disposed at a distance from the exterior material with a ventilation layer of flowing air; and an interior material disposed on the heat insulating material The interior side; and the interior finishing material attached to the interior side of the interior material.
於該隔熱材料之面向該通氣層之外表面配置有防濕層，並且該防濕層之透濕阻力A(m2‧h‧mmHg/g)、與包含該內飾修飾材料之該內飾材料之透濕阻力B(m2‧h‧mmHg/g)之比(A/B)限定為2以上。a moisture-proof layer is disposed on the outer surface of the heat insulating material facing the gas permeable layer, and the moisture-proof layer A (m 2 ‧h‧mmHg/g) of the moisture-proof layer and the inner surface containing the interior finishing material The ratio (A/B) of the moisture permeability resistance B (m 2 ‧h‧mmHg/g) of the decorative material is limited to 2 or more.

以下，根據圖式說明本發明之一實施形態。Hereinafter, an embodiment of the present invention will be described based on the drawings.
如圖1所示，本實施形態之用以防止夏季型結露之外壁構造(以下，有時簡稱為「外壁構造」)1包含：配置於室外側Ho之外飾材料2；與該外飾材料2之間隔著流動空氣之通氣層3配置之隔熱材料4；配置於該隔熱材料4之室內側Hi之內飾材料5；及貼附於該內飾材料5之室內側Hi之內飾修飾材料6，且主要使用於在夏季成為高溫多濕之炎熱地區之住宅等。As shown in Fig. 1, the outdoor type dew condensation outer wall structure (hereinafter sometimes simply referred to as "outer wall structure") 1 of the present embodiment includes: a decorative material 2 disposed outside the outdoor side Ho; and the exterior material 2, the heat insulating material 4 disposed between the ventilation layer 3 of the flowing air; the interior material 5 disposed on the indoor side Hi of the heat insulating material 4; and the interior of the interior side Hi attached to the interior material 5 The material 6 is modified and used mainly in a house in a hot and humid area in the summer.
該等構成構件被例如構建成矩形之框體7支承而形成為面板狀，固定於例如屋頂樑8與地基9之間。該框體7由例如木質材料或金屬材料等構成，且包括：在外壁構造1之上端側水平地延伸之上框材料7A；在下端側水平地延伸之下框材料7B；及於該等之間在左右兩端聯結之左右框材料(省略圖示)，且設置有於各框材料7A、7B之間延伸聯結於水平及垂直方向之各種聯結材料(省略圖示)。These constituent members are supported by, for example, a rectangular frame body 7 and formed in a panel shape, and are fixed between, for example, the roof beam 8 and the foundation 9. The frame body 7 is composed of, for example, a wood material or a metal material, and includes: a frame material 7A extending horizontally above an end side of the outer wall structure 1; a frame material 7B extending horizontally at a lower end side; and The left and right frame materials (not shown) that are joined at the left and right ends are provided with various bonding materials (not shown) that are extended in the horizontal and vertical directions between the frame materials 7A and 7B.
上述外飾材料2於上述框體7之室外側Ho且於上下隔著例如間隔件11A、11B安裝。較佳係，該外飾材料2，使用例如ALC(Autoclaved Lightweight Concrete，蒸壓輕質混凝土)等發泡混凝土板、或使水泥與木質增強材料之原料混合物之漿料熟化硬化之陶瓷系外飾面板等。The exterior material 2 is attached to the outdoor side Ho of the casing 7 and is vertically connected to the upper and lower sides by, for example, the spacers 11A and 11B. Preferably, the exterior material 2 is made of a foamed concrete slab such as ALC (Autoclaved Lightweight Concrete) or a ceramic exterior which is cured by hardening a slurry of a raw material mixture of cement and wood reinforcing material. Panels, etc.
又，於間隔件11A、11B上設置有於通氣層3與室外之間連通空氣之開口12。Further, the partitions 11A and 11B are provided with an opening 12 for communicating air between the ventilating layer 3 and the outside.
上述通氣層3由在外飾材料2與隔熱材料4之間沿上下延伸之空隙構成，使自間隔件11A、11B之開口12導引之外部空氣S沿上下通過，從而可將滯留於該通氣層3內之濕氣自例如屋簷下側換氣口14等向室外排出。The venting layer 3 is formed by a space extending vertically between the exterior material 2 and the heat insulating material 4, and the outside air S guided from the opening 12 of the spacers 11A, 11B is passed up and down, so that the venting can be retained in the venting The moisture in the layer 3 is discharged to the outside from, for example, the lower side ventilation port 14 of the eaves.
上述隔熱材料4係例如無間隙地配置於框體7之內部。於該隔熱材料4中，除例如岩絨或玻璃絨等纖維材料等之外，亦可使用耐水性及輕量性優異之聚苯乙烯泡沫等樹脂材料。The heat insulating material 4 is disposed inside the casing 7 without a gap, for example. In the heat insulating material 4, a resin material such as polystyrene foam excellent in water resistance and light weight can be used in addition to a fiber material such as rock wool or glass wool.
如於圖2中放大所示，於隔熱材料4之面向通氣層3之外表面4o上配置有由片材構成之防濕層13。As shown enlarged in FIG. 2, a moisture-proof layer 13 composed of a sheet is disposed on the outer surface 4o of the heat insulating material 4 facing the gas permeable layer 3.
又，於本實施形態中，上述防濕層13之透濕阻力A(m2‧h‧mmHg/g)與包含上述內飾修飾材料6之上述內飾材料之透濕阻力B(m2‧h‧mmHg/g)之比(A/B)限定為2以上。Further, in the present embodiment, the moisture permeability resistance A (m 2 ‧ h ‧ mmHg / g) of the moisture-proof layer 13 and the moisture permeability resistance B (m 2 ‧ of the above-mentioned interior material including the interior finishing material 6) The ratio (A/B) of h‧mmHg/g) is limited to 2 or more.
再者，於本說明書中，上述透濕阻力係依據JIS(Japanese Industrial Standards，日本工業標準)A1324、或JISZ0208中之圓筒平板法(cup method)測定之值。In the present specification, the moisture permeability resistance is a value measured in accordance with the cup method of JIS (Japanese Industrial Standards) A1324 or JIS Z0208.
此種外壁構造1中，防濕層13於外部空氣本身含有大量濕氣之炎熱地區之夏季，可阻斷因在室內側開放冷氣而產生之自室外側Ho朝向室內側Hi之濕氣M之氣流F，從而可抑制濕氣M滲入隔熱材料4之內部。進而，經阻斷之濕氣M藉由通氣層3內產生之外部空氣S之氣流而排出至室外，從而抑制滯留於外壁構造1之內部。In the outer wall structure 1, the moisture-proof layer 13 can block the airflow of the moisture M from the outdoor side Ho toward the indoor side Hi due to the opening of the cold air on the indoor side in the hot summer region where the outside air itself contains a large amount of moisture. F, thereby suppressing the penetration of the moisture M into the inside of the heat insulating material 4. Further, the blocked moisture M is discharged to the outside by the airflow of the outside air S generated in the vent layer 3, thereby suppressing the retention inside the outer wall structure 1.
又，包含內飾修飾材料6之內飾材料5之透濕阻力B較小，故可有效地將滲入防濕層13與內飾材料5之間之濕氣M向低溫低濕之室內側Hi排出，從而例如可抑制於隔熱材料4之內部等之壁內產生結露。Moreover, since the moisture permeability B of the interior material 5 including the interior finishing material 6 is small, the moisture M which penetrates between the moisture-proof layer 13 and the interior material 5 can be effectively made to the indoor side of the low temperature and low humidity. The discharge is, for example, suppressed from occurring in the wall of the inside of the heat insulating material 4 or the like.
因此，本實施形態之外壁構造1藉由配置於隔熱材料4之室外側Ho之防濕層13、與配置於隔熱材料4之室內側Hi之透濕性優異之內飾材料5的協同效果，可於炎熱地區之夏季抑制在隔熱材料4之內部等之壁內產生結露，從而可有效地防止夏季型結露。Therefore, in the outer wall structure 1 of the present embodiment, the moisture-proof layer 13 disposed on the outdoor side Ho of the heat insulating material 4 and the interior material 5 excellent in moisture permeability of the indoor side Hi disposed on the heat insulating material 4 are coordinated. The effect is to suppress dew condensation in the wall of the heat insulating material 4 in the summer in a hot area, thereby effectively preventing summer type condensation.
