支持板 3 1に筒体 3 4が取り付けられたファン 3 0は、 支持板 3 1を 左側面部シート 2 4の内側に配置し、 筒体 3 4を取り付け孔 2 7より外 方へ突出させた状態とし、 支持板 3 1周部の縫着孔 3 1 Bを利用して縫
着され、 縫着部分にはゴム引き或いは樹脂の塗布により非通気性の加工 が施される。 The fan 30 in which the cylinder 34 is attached to the support plate 31 has the support plate 31 arranged inside the left side seat 24 and the cylinder 34 protruding outward from the mounting hole 27. State, and sewing is performed using the sewing holes 3 1 B around the support plate 3 1. The sewn part is subjected to non-breathable processing by rubberization or resin application.
天井幕 1 8は本体 2 Aの天井となる部分を覆った後、 その外周の取り 付け代 1 8 Aを第 1 1図に示すように、 支持樋 1 2内に引っ張り、 支持 樋 1 2の各ボルト軸 1 3に取り付け代 1 8の止め孔 1 9を深く挿入し、 外周の取り付け代 1 8をボルト軸 1 3に挿入することによって天井幕 1 8が本体 2 Aに固定される。 The ceiling curtain 18 covers the ceiling of the main unit 2A, and then pulls the mounting margin 18A of the outer periphery into the support gutter 12 as shown in Fig. The ceiling curtain 18 is fixed to the main body 2A by inserting the retaining hole 18 of the mounting margin 18 deep into each bolt shaft 13 and inserting the mounting margin 18 of the outer periphery into the bolt shaft 13.
しかる後、 各支持樋 1 2のボルト軸 1 3には非通気性の帯状クッショ ン板 3 6が取り付けられる。 第 1 2図に示すように帯状クッション板 3 6はボルト軸 1 3と等間隔に通孔 3 6 Aを有する帯体からなり、 天井幕 1 8の取り付け代 1 8 A、 屋根幕 2 0の取り付け代 2 1 B、 2 2 B、 2 3 B、 2 4 Bをボルト軸 1 3に取り付けて締めつけた際に密閉構造を構 成するためのものである。 Thereafter, a non-breathable band-shaped cushion plate 36 is attached to the bolt shaft 13 of each support gutter 12. As shown in FIG. 12, the band-shaped cushion plate 36 is formed of a band having a through hole 36 A at an equal interval to the bolt shaft 13, and a mounting margin 18 A for the ceiling curtain 18 and a roof curtain 20. This is to form a sealed structure when the mounting allowances 21B, 22B, 23B, and 24B are attached to the bolt shaft 13 and tightened.
次いで、 内面に芯材 5 0が固定されて屋根形に形成された屋根幕 2 0 を、 その前面部シート 2 1を本体 2 Aの正面側に向けるとともに、 天井 幕 1 8の上部に配置し、 屋根幕 2 0の右側の引き紐 2 6を本体 2 A右側 の支持管 1 5の転子 1 5 Aを経て管内に導き、 管外へ引き出して引っ張 り状態に仮止めする。 Then, the roof curtain 20 having a core material 50 fixed to the inner surface and formed into a roof shape is placed on the top of the ceiling curtain 18 with the front sheet 21 facing the front side of the main body 2A. Then, the pull cord 26 on the right side of the roof curtain 20 is guided into the pipe through the trochanter 15 A of the support pipe 15 on the right side of the main body 2 A, pulled out of the pipe, and temporarily fixed in a pulled state.
それから、 屋根幕 2 0の周部の取り付け代 2 1 B、 2 2 B、 2 3 B、 2 4 Bを支持樋 1 2内に引っ張り、 支持樋 1 2の各ボルト軸 1 3に止め 孔 2 5を順次挿入する。 周部の取り付け代 2 1 B、 2 2 B、 2 3 B、 2 4 Bの止め孔 2 5を全てボルト軸 1 3に挿入後は、 第 1 3図に示すよう に、 各ボルト軸 1 3にナット 3 9を締着し、 屋根幕 2 0の周部が密着固 定される。 Then, the mounting margin 21 B, 22 B, 23 B, 24 B of the peripheral part of the roof curtain 20 is pulled into the support gutter 12, and the bolt hole 13 of each bolt shaft 13 of the support gutter 12 is made. Insert 5 sequentially. After inserting all the fixing holes 25 of the peripheral parts 2 1 B, 22 B, 23 B and 24 B into the bolt shaft 13, as shown in Fig. 13, each bolt shaft 13 A nut 39 is fastened to the periphery, and the periphery of the roof curtain 20 is tightly fixed.
その後、 仮引きした引き紐 2 6が本止めされる。 この本止めは第 1 4 図に示すように、 引き紐 2 6の端部に錘 4 1を吊るす力、 或いは固定具
4 2と引き紐 2 6間に引きばね 4 3を介装して屋根幕 2 0が所定の形状 を保つようにされる。 尚、 弓 Iき紐 2 6の本止めに際しては不動状に固定 してもよいが、 第 1 4図に示すように可動状とすると温度や気圧の変化 に柔軟に対応することができるため好ましい。 かくして、 引き紐 2 6を 本止めした状態の天井幕 1 8と屋根幕 2 0との間の屋根空間部 Sは、 フ アン 3 0の通気孔 3 1 Aを除いて密閉空間とされる。 Thereafter, the temporarily pulled cord 26 is permanently stopped. As shown in Fig. 14, this permanent stop is a force that suspends the weight 41 on the end of the drawstring 26 or a fixing device. The roof curtain 20 is maintained in a predetermined shape by interposing a pull spring 43 between the pull cord 42 and the drawstring 26. When the bow I string 26 is permanently fixed, it may be fixed immovably. However, as shown in FIG. 14, it is preferable that the bow is movable so that it can flexibly respond to changes in temperature and pressure. . Thus, the roof space portion S between the ceiling curtain 18 and the roof curtain 20 in a state where the drawstring 26 is permanently fixed is a closed space except for the vent hole 31A of the fan 30.
この状態において、 ファン 3 0のモータ Mに通電して回転羽根 3 3を 回転させて屋根空間部 Sの空気を外部へ排出すると、 屋根空間部 Sが外 気よりも負圧 (低圧) となるため、 第 1 5図に示すように、 天井幕 1 8 は本体 2 Aの上方側へと引っ張られ、 屋根幕 2 0は緊張状態に保持され る。 また、 回転羽根 3 3を回転させて外部の空気を屋根空間部 Sへと供 給すると、 屋根空間部 Sが外気よりも正圧 (高圧) となるため、 第 1 6 図に示すように、 天井幕 1 8及び屋根幕 2 0は外向きに押し出され、 屋 根幕 2 0は緊張状態に保持される。 In this state, when the motor M of the fan 30 is energized and the rotating blades 33 are rotated to discharge the air in the roof space S to the outside, the roof space S has a negative pressure (lower pressure) than the outside air. Therefore, as shown in FIG. 15, the ceiling curtain 18 is pulled upward from the main body 2A, and the roof curtain 20 is held in a tensioned state. When the rotating blades 33 are rotated to supply external air to the roof space S, the roof space S has a higher positive pressure (higher pressure) than the outside air, and as shown in FIG. The ceiling curtain 18 and the roof curtain 20 are pushed outward, and the roof curtain 20 is kept in tension.
そのため、 屋根幕 2 0は皺のない優れた形状の外観となり、 しかも屋 根幕 2 0内側には空気が充填された芯材 5 0が固定されているので、 屋 根空間部 Sの空気圧の変動が生じても屋根幕形状が形崩れしにくく、 さ らには屋根全体が軽量となるため、 地震に対する耐久性にも優れる。 尚、 本発明においては、 屋根空間部 Sから排出された空気を芯材 5 0 内部に供給する構成を採用することもできる。 Therefore, the roof curtain 20 has an excellent appearance without wrinkles, and the core material 50 filled with air is fixed inside the roof curtain 20, so that the air pressure of the roof space S is reduced. Even if there is a change, the shape of the roof curtain is less likely to lose its shape, and the entire roof is lighter, making it more resistant to earthquakes. In the present invention, a configuration in which the air discharged from the roof space S is supplied to the inside of the core member 50 may be adopted.
この構成を採用する場合には、 第 1 7図に示すように、 芯材 5 0の空 気孔 5 1に設けられた開閉栓 5 2を屋根幕 2 0 (図示例では左側面部シ ート 2 4 ) の外側に突出させて、 接続ホース 6を介して前記筒体 3 4の 開放端とこの開閉栓 5 2を接続すればよい。 尚、 このとき開閉栓 5 2と 屋根幕 2 0との境界部分には樹脂塗布等の手段により気密処理が施され るのは勿論である。 また、 右側面部に取り付けられた芯材 5 0への空気
