PROBLEM TO BE SOLVED: To provide a large-scale greenhouse and a warehouse, which is generally an H-shaped steel frame structure, but instead of which a popular-sized straight pipe is partly provided side by side and connected to the structure to provide an inexpensive and strong structure. SOLUTION: In a house of a pillar and a roof having a connecting structural material in an inner and outer double aggregate, a vertical outer straight pipe and a slanted inner side are provided in order to secure strength equivalent to a steel frame within a necessary range. A rope a and a bracing material b1 are arranged between the straight pipes in a direction to push up the inner pipe, and a pillar structure composed of a connecting material, and an oblique outer straight pipe that determines the outer shape of the roof and a substantially adjacent inner pipe In a house made up of a beam structure in which a wire for pushing up a straight pipe with a rope a and a bracing material b1 is connected to a pipe coupling material, a connecting material composed of the rope a and the bracing material b1 is formed by a roof snow load P or the like. A structure in which the shearing force caused by the difference between the tension and compression of the inner and outer pipes is loaded like the diagonal member of a truss, and it can be constructed by simple assembly technology on site. [Selection diagram] Figure 1【課題】大型温室や倉庫は一般にＨ形鋼の鉄骨構造であるが、代わりに普及サイズの直管パイプを一部に併設させ連結させることにより、安価で強度ある構造を提供する。【解決手段】内外二重の骨材に連結構造材を有する柱材と屋根のハウスで、必要な範囲内で鉄骨並みの強度を確保させるために、垂直な外側直管パイプと傾設の内側直管パイプの間にロープａと突っ張り材ｂ１が内部パイプを突き上げる方向に配置され、結合材で構成された柱構造と、屋根の外形を決める斜設の外側直管パイプと内側に略併設の直管パイプをロープａと突っ張り材ｂ１で外側パイプを上に突き上げる配線がパイプ結合材と結合した梁構造で成り立つハウスにおいて、そのロープａと突っ張り材ｂ１でなる連結材が屋根積雪加重Ｐなどにより内外パイプの引張と圧縮の差で生じる剪断力を、トラスの斜材のように荷重負担し、又それが現場での簡単組立技術で建築可能になる構造。【選択図】図１
