組す、bとの位置関係を示す。As shown in Fig. 1-■, the membrane structure A of the present invention is constructed by constructing cable beams a made by connecting an upper string cable 1 and a lower string cable 2 with a connecting material 3, and extending orthogonally between the cable beams a and b. However, as shown in (3), by pulling the lower string cable 2, tension is introduced into the membrane material 4 stretched over the upper string cable 1. FIG. 2 shows the positional relationship between the cable beam a and the frame b.
骨組すは鉄骨をトラス梁状に組み立てる、もしくは上記

またはコンクリート梁等により形成される。The framework is constructed by assembling steel frames in the form of truss beams, or by constructing cable beams made of the above-mentioned upper and lower string cables and connecting materials.
Or formed by concrete beams, etc.
上弦ケーブル1は第1図−1に示すように骨組す、bの
上端間に水平、もしくは下に凸に架設され、ここに接続
される。As shown in FIG. 1-1, the upper string cable 1 is installed horizontally or downwardly convexly between the upper ends of the frame b, and is connected thereto.
一方下弦ケーブル2は骨組す、 bの下端間に下向き
(負)の曲率、すなわち上に凸に架設され、ここにロー
ラ5等によって滑動自在に支持される。On the other hand, the lower string cable 2 is installed between the lower ends of the frame b with a downward (negative) curvature, that is, an upward convexity, and is slidably supported there by rollers 5 and the like.
上弦ケーブル1と下弦ケーブル2とは1本、または長さ
の異なる複数本のつなぎ材3によって連結され、また膜
材4は上弦ケーブル1上に張り付けられて上弦ケーブル
1の挙動に追従する。The upper string cable 1 and the lower string cable 2 are connected by one or a plurality of connecting members 3 of different lengths, and the membrane material 4 is pasted on the upper string cable 1 to follow the behavior of the upper string cable 1.
膜材4への張力導入は第゛1図−1の状態において、下

ように上向き(正)の曲率にすることによって行われる
。Tension is introduced into the membrane material 4 by pulling one end or both ends of the lower string cable 2 outward to reduce its curvature, that is, the rise, in the state shown in Figure 1-1, and then pulling the upper string cable 1 downward using the connecting material 3. This is done by pulling it towards the center and making it have an upward (positive) curvature like ■.
上弦ケーブル1と下弦ケーブル2の端部は第3図に示す

きる。This invention is as described above, and since the cable beam consisting of the upper string cable on which the membrane material is stretched and the lower string cable that applies tension to the cable beam constitutes the structure, the roof structure can be simplified and lightened. At the same time, since the membrane material follows the shape of the upper string cable, its original form can be utilized.
