To provide a strut device that protects a greenhouse from collapsing against a load from above due to snow or a load from side due to wind. SOLUTION: A pipe-like support column 1 shaped like a crotch, and a pipe and a base 3 are fixed to both ends of a U-shape by screws 4 such as bolts or welding, and a buffer such as urethane or rubber is provided inside. The frame 2 of the greenhouse is inserted and fixed to the clasp 5 in which the movement between the metals is eased by sticking the material. In addition, the jack base 6 is placed under the pipe-shaped column 1 and the jack is raised to prevent the vertical load caused by snow and the horizontal load caused by wind, thereby increasing the strength of the greenhouse. Prevent the house from collapsing. [Selection] Figure 1【課題】ビニールハウスを雪による上からの負荷や風による横からの負荷に対して倒壊から守る支柱装置を提供する。【解決手段】刺股のような形のパイプ状の支柱１で、Ｕ字状の両端にパイプと台座３との間をボルト等のネジ４や溶接により固定し、内側にウレタンやゴム等の緩衝材を貼ることで金属同士の動きを緩和させた留め金５にビニールハウスの骨組み２を差し込み固定する。また、パイプ状の支柱１の下の部分にジャッキベース６を入れて、ジャッキを上げることで雪による縦からの負荷や風による横からの負荷を防ぐことでビニールハウスの強度を増加し、ビニールハウスの倒壊を防ぐ。【選択図】図１
