A wall surface frame on the outer periphery of the greenhouse building (2) is configured by using a wire such as a single pipe, and a roof group is configured by tension wires (11 to 14) that are stretched in the front-rear and left-right directions. The tension force of the tension wire is received on the installation surface by the anchor tension wires (15, 17, 18). Only the compression force acts on each column of the wall surface frame, and the bending force does not substantially act. A large building can be easily constructed using wire rods such as small-diameter single pipes. A large greenhouse with high daylighting rate can be easily constructed without using heavy building materials such as steel frames.温室用建物(2)の外周の壁面枠組を単管などの線材を用いて構成し、屋根組を、前後左右方向に引張状態で架け渡した引張ワイヤ(11~14)によって構成する。引張ワイヤの引張力を、アンカー用引張ワイヤ(15、17、18)によって、設置面で受ける。壁面枠組の各支柱には圧縮力のみが作用し、曲げ力が実質的に作用しない。小径の単管等の線材を用いて大きな建物を簡単に構築できる。鉄骨材等の重量建材を用いることなく、採光率の高い大きな温室を簡単に構築できる。
