PROBLEM TO BE SOLVED: To provide techniques enabling assembling a framing structure to simplify compared with conventional techniques.SOLUTION: A method for assembling a frame structure comprising a pair of elongated first base members placed on the ground, and a frame surface portion which is disposed in a plane orthogonal to the longitudinal direction of the first base members and erected in an upright posture comprises: a step of placing a pair of first base members on the ground parallel to each other at a predetermined interval； a frame surface portion-linking step of linking to each of the pair of first base members rotatably around a frame rotation axis extending in the width direction orthogonal to the longitudinal direction of the first base members, in a state in which the frame surface portion is in a sideways posture in which the frame surface portion is oriented along the ground； and erecting step of changing the frame surface portion from the sideways posture to the upright posture by rotating the frame surface portion with respect to the pair of first base members around the frame rotation axis； and a posture fixing step of fixing the frame surface portion in a state of standing posture.SELECTED DRAWING: Figure 2E【課題】骨組構造体の組み立てを従来に比べて簡易化することの可能な技術を提供する。【解決手段】地面に載置される長尺な一対の第１ベース部材と、第１ベース部材の長手方向に直交する平面内に配置されると共に起立した起立姿勢で立設される架構面部とを備える骨組構造体の組み立て方法であって、一対の第１ベース部材を所定間隔をおいて平行に地面に載置する工程と、架構面部を地面に沿わせた横倒し姿勢とした状態で、一対の第１ベース部材の各々に対して、第１ベース部材の長手方向に直交する幅方向に延びる架構回転軸を中心として回動自在に架構面部を連結する架構面部連結工程と、架構回転軸を中心として架構面部を一対の第１ベース部材に対して回動させることで架構面部を横倒し姿勢から起立姿勢に変更させる起立工程と、架構面部を起立姿勢の状態で固定する姿勢固定工程を有する。【選択図】図２Ｅ
