透光性が十分に活用されない。(Problems to be Solved by the Invention) As described above, in the conventional structure, in order to stretch the film material on the structure of the single-layer dome, the purlin material is installed on the arc-shaped member via the bundle material. It is necessary, and the presence of the same bundle material and the main material makes the roof surface from the inside of the dome look like a multi-layered dome, which is annoying, and the translucency of the film material is not fully utilized.
更にまた前記のように構成された単層ドームの構格の
面外剛性が小さい。Furthermore, the out-of-plane rigidity of the structure of the single-layer dome configured as described above is small.
本発明は前記従来技術の有する問題点に鑑みて提案さ

いる。(Means for Solving the Problems) In order to achieve the above object, the structure of the dome for membrane roof according to the present invention is arranged radially between the dome top and the dome lower end outer periphery. In a structure of a dome including an arcuate member and a connecting member arranged in a circumferential direction between the arcuate members, the arcuate members adjacent to each other in the circumferential direction are provided with a height difference. The connecting members are positioned in a zigzag manner between adjacent arc-shaped members.
（作用） 本発明に係る膜屋根用ドームの構格によれば、円周方

直接張設することによって、同膜材のサグが確保され、
従来のように膜材張設のための母屋材及び束材が不要と
なる。(Operation) According to the structure of the dome for a membrane roof according to the present invention, since the arcuate members adjacent to each other in the circumferential direction are located with a height difference, the arcuate members located at the upper part are separated from each other. By stretching the film material directly over the area, sag of the film material is secured,
As in the conventional case, a purlin material and a bundle material for tensioning the membrane material are unnecessary.
また前記したように円弧状部材が交互に上下に位置し
てジグザグ状に配設されたことによって、構格の面外剛
性が増大する。Further, as described above, the arcuate members are alternately arranged vertically and arranged in a zigzag shape, so that the out-of-plane rigidity of the structure is increased.
（実施例） 以下本発明を図示の実施例について説明する。(Examples) The present invention will be described below with reference to illustrated examples.
（１）はドーム頂点を中心として、ドーム下端外周縁
との間に放射状に配設された円弧状部材で、円周方向に
相隣る同円弧状部材（１）が互いに高低差を設けて配設

って繋ぎ材（２）が接続されている。(1) is an arcuate member radially arranged around the dome apex with the outer edge of the lower end of the dome. The arcuate members (1) adjacent to each other in the circumferential direction are provided with a height difference from each other. The connecting members (2) are arranged along the circumferential direction across the respective arcuate members (1).
図中（４）は膜材に張力を導入するケーブルである。 In the figure, (4) is a cable for introducing tension into the film material.
