TRUSS BEAM
To provide a truss beam which has a buckling preventing structure capable of being easily attached to a joint part and which can handle a frame similarly to the filling material.SOLUTION: A truss beam (1) has an upper chord member (2), a lower chord member (3) and a plurality of diagonal members (4). The lower chord member includes a first lower chord member (7) made of H-shaped steel and a second lower chord member (8) made of H-steel. A joint part (9) between the first lower chord member and the second lower chord member has a yield joint plate (10) attached to webs (7a, 8a) of the H-steel, and a restraining member (12) attached to a pair of flanges of the H-steel (1). Since the yield joint plate is inserted into the gap between the web of the H-steel and the restraining member, buckling is prevented.SELECTED DRAWING: Figure 1
【課題】接合部に容易に取り付けることができる座屈防止構造を有し、充腹材と同様に架構を扱うことができるトラス梁を提供する。【解決手段】トラス梁（１）は、上弦材（２）、下弦材（３）及び複数の斜材（４）を有する。下弦材は、Ｈ形鋼からなる第１下弦材（７）とＨ形鋼からなる第２下弦材（８）とを有する。第１下弦材及び第２下弦材間の接合部（９）は、Ｈ形鋼のウェブ（７ａ，８ａ）に取り付けられた降伏継手板（１０）と、Ｈ形鋼の１対のフランジに取り付けられた拘束部材（１２）とを有する。降伏継手板は、Ｈ形鋼のウェブと拘束部材との隙間に挿通された状態となるため、座屈が防止される。【選択図】図１
