本出願人は、パラペット部内の屋内空気をスムーズに排出し換気できるパラペット換気装置を既に提案している（特許文献１）。
特許文献１に記載のパラペット換気装置を図５に示す。
図５は同パラペット用換気装置の要部断面図である。
パラペット１１０は、構造用合板１１１の上部に配置される上枠材１１２と、構造用合板１１１の外面に配置される通気胴縁１１３と、通気胴縁１１３の外面に配置される外壁１１４と、上枠材１１２及び外壁１１４の上方を覆う笠木１１５とを有している。
笠木１１５は、上枠材１１２及び外壁１１４の上部を覆う天面部１１５ａと、天面部１１５ａから垂下して外壁１１４の側方に配置される垂下部１１５ｂとを有している。
換気部材１２０は、外壁１１４の上端に形成されるパラペット開放部１３０に配置される。
換気部材１２０の外片１２２には通気開口１３３が形成され、換気部材１２０の内片１２４の上部は通気胴縁１１３に連通し、換気部材１２０の内部には通気空間１３２が形成されている。
従って、通気胴縁１１３から上昇する空気は、内片１２４の上部から換気部材１２０の内部の通気空間１３２を通過し、通気開口１３３から排出される。
なお、通気開口１３３は、上下から支持部材に立脚支持された開口部遮断壁が出窓状に張り出して形成されている（段落番号００２３）。
また、外気導入を阻止する遮蔽板１２６は、外片１２２と内片１２４とで形成される通気空間１３２の中央付近に配置している（段落番号００３０）。
The present applicant has already proposed a parapet ventilation device that can smoothly exhaust and ventilate indoor air in the parapet section (Patent Document 1).
The parapet ventilator described in Patent Document 1 is shown in FIG.
FIG. 5 is a cross-sectional view of a main part of the parapet ventilation device.
The parapet 110 includes an upper frame member 112 disposed on an upper portion of the structural plywood 111, a ventilation trunk edge 113 disposed on the outer surface of the structural plywood 111, an outer wall 114 disposed on the outer surface of the ventilation plywood edge 113, The upper frame material 112 and the headboard 115 which covers the upper part of the outer wall 114 are provided.
The headboard 115 includes a top surface portion 115 a that covers the upper frame member 112 and the upper portion of the outer wall 114, and a hanging portion 115 b that is suspended from the top surface portion 115 a and is disposed on the side of the outer wall 114.
The ventilation member 120 is disposed in a parapet opening portion 130 formed at the upper end of the outer wall 114.
A ventilation opening 133 is formed in the outer piece 122 of the ventilation member 120, an upper portion of the inner piece 124 of the ventilation member 120 communicates with the ventilation trunk edge 113, and a ventilation space 132 is formed in the ventilation member 120.
Therefore, the air rising from the ventilator edge 113 passes through the ventilation space 132 inside the ventilation member 120 from the upper part of the inner piece 124 and is discharged from the ventilation opening 133.
The vent opening 133 is formed by projecting an opening blocking wall supported by a support member from above and below in the form of a bay window (paragraph number 0023).
Further, the shielding plate 126 for preventing the introduction of outside air is arranged near the center of the ventilation space 132 formed by the outer piece 122 and the inner piece 124 (paragraph number 0030).
しかし、図６に示すパラペット換気装置は、換気部材１２０が外壁１１４より外方に突出している。このため、笠木１１５の垂下部１１５ｂと換気部材１２０の通気開口１３３との間に通気のためのスペースを設ける必要があり、笠木１１５の中心位置を上枠材１１２の中心位置からずらして配置する必要があった。
また、笠木１１５のサイズを大きなものに取り替える必要が生じる場合もあった。
However, in the parapet ventilation apparatus shown in FIG. 6, the ventilation member 120 protrudes outward from the outer wall 114. For this reason, it is necessary to provide a space for ventilation between the hanging portion 115 b of the headboard 115 and the ventilation opening 133 of the ventilation member 120, and the center position of the headboard 115 is shifted from the center position of the upper frame member 112.

As shown in FIG. 4A, a part of the lower piece 23 is extended above the ventilation trunk edge 13 so that the depth dimension L3 of the ventilation path 31 is smaller than the depth dimension L4 of the ventilation trunk edge 13. ing.
According to the present embodiment, since the depth dimension L3 of the ventilation path 31 can be maintained constant using the spacer member 40, a part of the lower piece 23 can be extended above the ventilation trunk edge 13.
Further, the outer piece 22 is not protruded outward from the outer surface of the outer wall 14.
According to the present embodiment, since the distance between the outer piece 22 and the hanging portion 15b of the headboard 15 can be secured, the center of the headboard 15 can be arranged in accordance with the center of the upper frame member 12.
As shown in FIG. 4A, the air that has risen up the ventilation trunk edge 13 passes through the ventilation path 31 and the ventilation space 32 and is discharged from the ventilation opening 33.
図４（ｂ）に示すように、所定の風速以上の条件で通気開口３３から空気が流入すると、遮蔽板２６は変位し、遮蔽板２６に設けた弾性材２９が内片２４に当接し、遮蔽板２６によって通気空間３２は遮断される。従って、外気の流入によって雨水が浸入することを防止することができる。 As shown in FIG. 4 (b), when air flows in from the ventilation opening 33 under conditions of a predetermined wind speed or more, the shielding plate 26 is displaced, and the elastic material 29 provided on the shielding plate 26 contacts the inner piece 24, The ventilation space 32 is blocked by the shielding plate 26. Therefore, it is possible to prevent rainwater from entering due to the inflow of outside air.
以上のように、本実施例によれば、スペーサー部材４０によって通気路３１の奥行き寸法Ｌ３を一定に維持できるため、内片２４を構造用合板１１に近づけることができ、内片２４を構造用合板１１に近づけた寸法だけ外片２２を構造用合板１１に近づけることができ、その結果外壁１４の外面からの外片２２の突出寸法を小さくできる。従って、外片２２と笠木１５の垂下部１５ｂとの距離を確保できるため、笠木１５の中心を上枠材１２の中心にあわせて配置することができる。 As described above, according to the present embodiment, the depth L3 of the air passage 31 can be kept constant by the spacer member 40. Therefore, the inner piece 24 can be brought close to the structural plywood 11, and the inner piece 24 is used for the structure. The outer piece 22 can be brought closer to the structural plywood 11 by a dimension closer to the plywood 11, and as a result, the projecting dimension of the outer piece 22 from the outer surface of the outer wall 14 can be reduced. Therefore, since the distance between the outer piece 22 and the hanging portion 15b of the headboard 15 can be secured, the center of the headboard 15 can be arranged in accordance with the center of the upper frame member 12.
図５は本発明の他の実施例によるパラペット用換気装置の要部断面図である。
上記実施例では、構造用合板１１を用いたパラペット用換気装置を示したが、本実施例によるパラペット用換気装置は、構造用合板１１を用いないものである。
本実施例では、上枠材１２は柱１７の上部に配置され、通気胴縁１３は柱１７の外面に配置される。ここで柱１７には、両側に配置される支柱と、支柱の間に配置される間柱がある。その他の構造は上記実施例と同一であるので同一符号を付して説明を省略する。
本実施例によれば、スペーサー部材４０によって通気路３１の奥行き寸法Ｌ３を一定に維持できるため、内片２４を柱１７に近づけることができ、内片２４を柱１７に近づけた寸法だけ外片２２を柱１７に近づけることができ、その結果外壁１４の外面からの外片２２の突出寸法を小さくできる。従って、外片２２と笠木１５の垂下部１５ｂとの距離を確保できるため、笠木１５の中心を上枠材１２の中心にあわせて配置することができる。
FIG. 5 is a cross-sectional view of an essential part of a parapet ventilation device according to another embodiment of the present invention.
Although the parapet ventilator using the structural plywood 11 is shown in the above embodiment, the parapet ventilator according to the present embodiment does not use the structural plywood 11.
In the present embodiment, the upper frame member 12 is disposed on the upper portion of the column 17, and the ventilation trunk edge 13 is disposed on the outer surface of the column 17. Here, the pillar 17 includes a pillar disposed on both sides and a spacer disposed between the pillars. Since other structures are the same as those in the above embodiment, the same reference numerals are given and description thereof is omitted.
According to the present embodiment, since the depth dimension L3 of the air passage 31 can be kept constant by the spacer member 40, the inner piece 24 can be brought closer to the pillar 17, and the outer piece can be brought closer to the pillar 17 by the dimension. 22 can be brought close to the pillar 17, and as a result, the projecting dimension of the outer piece 22 from the outer surface of the outer wall 14 can be reduced. Therefore, since the distance between the outer piece 22 and the hanging portion 15b of the headboard 15 can be secured, the center of the headboard 15 can be arranged in accordance with the center of the upper frame member 12.
