PROBLEM TO BE SOLVED: To provide a low-cost construction method for truss beam that enables simple position correction, at erection, of a frame structure that uses a precast reinforced concrete truss beam.SOLUTION: A construction method for a truss beam assembles and mutually contact-bonds precast concrete upper chord member, lower chord member, diagonal member receiving member and diagonal member. While the diagonal member is supported by a supporting unit member via a supporting member receiving metal attached on the diagonal member, a jack assembled in the supporting unit member adjusts the erection position. Then, the diagonal member and the diagonal member receiving member are contact bonded and joined by applying tension to a precast steel wire inserted through the cross section of each of the members while an end part of the diagonal member and a protruded part of the diagonal member receiving member are fixed temporarily by sandwiching between a pair of connecting metals placed along a lateral face of the diagonal member.
【課題】プレキャスト鉄筋コンクリート部材を用いたトラス梁の架構構造物を、低コストで、かつ、容易に建込み時に位置補正することが可能なトラス梁の構築方法を提供することを課題とする。【解決手段】プレキャストコンクリート造の上弦部材、下弦部材、斜材受け材、及び斜材を組上げて互いに圧着されるトラス梁の構築方法であって、前記斜材を、当該斜材に取り付けた支保工受け金物を介して支保工ユニット材で支持させつつ、当該支保工ユニット材に組み込まれたジャッキで建込み位置を調整した後、前記斜材の端部と前記斜材受け材の凸部を、前記斜材の側面に添わせた一対の連結金物で挟んで仮固定させた状態で、前記斜材と前記斜材受け材を、各断面内に挿通させたＰＣ鋼線を緊張して圧着接合することを特徴とする。【選択図】図１
