To provide a structure with strength at a low price by using ordinary sized straight pipes and an accouplement instead of a steel-frame structure generally used for a large sized greenhouse or a storehouse.SOLUTION: A house illustrated in Fig. 5 is constituted by a column material including a double inner and outer aggregate and an arranged tabular accouplement, and a roofing material. The house comprises: a columnar structure in which a tabular accouplement installed between a vertical outside straight pipe and a slanted inside straight pipe is joined by a coupling material to secure the same strength as steel frame within a required range； and a beam structure fastened and joined by the tabular accouplement arranging diagonal outside straight pipes deciding outer shape of the roof and inside straight pipes parallely installed at a plurality of locations, in which the structure enables shear force of the accouplement occurred by difference between stretch of the inside and outside pipes and compression thereof caused by weight of snow coverage on roof and the like to decentralize like diagonal members in the truss, and can be built by simple assemble technique on site.SELECTED DRAWING: Figure 5【課題】大型温室や倉庫は一般に鉄骨構造であるが、代わりに普及サイズの直管パイプと連結材により、安価で強度ある構造を提供する。【解決手段】図５のごとく内外二重の骨材と配設された板状連結材を有する柱材と屋根材で構成されるハウスで、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配設する板状連結材が締結材で接合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複数ヶ所に配設する板状連結材で締結接合構成された梁構造で成り立つハウスにおいて、その連結材が屋根積雪加重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、役割負担し、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５
