PROBLEM TO BE SOLVED: To provide an agricultural house comprising one rod-shaped material provided as a linear rod-shaped material, a plurality of other rod-shaped materials arranged across the longitudinal direction of the linear rod-shaped material at different positions at an angle, and fastening members arranged on the other rod-shaped materials, the arrangement positions of the fastening members being their positions on the straight line； and to provide a method for assembling the agricultural house.SOLUTION: According to the present invention, a fastening member 12 and a wedge member 22 are used to join two rod-shaped materials, an arched rod-shaped material 1 and a farmhouse rod-shaped material 2B, which are crossed and arranged at an angle. The arched rod-shaped material 1 intersects at a plurality of positions on the farmhouse rod-shaped material 2B provided as a linear rod-shaped material extending linearly. Recessed portions 41 are respectively formed in the fastening members 12 arranged on the respective positions and serve as a leveling-line contact portion for bringing a leveling line 40 into contact therewith. The arrangement positions of the respective fastening member 12 on the arched rod-shaped material 1 are provided as the respective positions in the straight line by bringing the leveling line 40 into contact with the recessed portions 41.SELECTED DRAWING: Figure 21【課題】一方の棒状材が直線状棒状材となっていて、この直線状棒状材の長さ方向の複数箇所で角度をなして交差配設される複数本の他方の棒状材に抱持部材を配置するに際し、これらの抱持部材の配置位置を、直線におけるそれぞれの位置とすることができる農業用ハウス及びその組み立て方法を提供すること。【解決手段】角度をなして交差配設された２本の棒状材であるアーチ状棒状材１と母屋棒状材２Ｂを結合するために抱持部材１２と楔部材２２が用いられ、直線的に延びる直線状棒状材である母屋棒状材２Ｂの複数箇所でアーチ状棒状材１が交差し、これらの箇所に配置されているそれぞれの抱持部材１２に、水糸４０を接触させるための水糸接触部となっている凹部４１が設けられ、抱持部材１２のアーチ状棒状材１における配置位置を、凹部４１に水糸４０を接触させることで、直線におけるそれぞれの位置とする。【選択図】図２１
