TRUSS BEAM
To provide a truss beam in which a buckling restraining member whose neck folding buckling is prevented is easily disposed in a part of a chord member and in which a frame can be handled just like a full web member.SOLUTION: A truss beam (1) includes an upper chord member (2), a lower chord member (3), and a plurality of diagonal members (4). A part of the lower chord member (3) is constituted of a buckling restraining member (8). The buckling restraining member (8) comprises: a pair of joint bodies (10, 10) joined to a main body portion (6) of the lower chord member (3); a core material (11) whose end portions are respectively fixed to the corresponding joint body (10); a pair of restraining members (12, 12) which respectively has a cylinder shape through which the core material (11) is inserted and whose one end side is fixed to the corresponding joint body (10); and a filler (13) filled in the restraining member (12) so as not to adhere to the core material (11).SELECTED DRAWING: Figure 1
【課題】首折れ座屈が防止された座屈拘束部材を容易に弦材の一部に配置でき、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（３）の一部は、座屈拘束部材（８）からなる。座屈拘束部材（８）は、下弦材（３）の本体部（６）に接合される１対の接合体（１０，１０）と、両端部がそれぞれ対応する接合体（１０）に固定された芯材（１１）と、それぞれ、芯材（１１）が挿通された筒状をなし、一端側が対応する接合体（１０）に固定された１対の拘束材（１２，１２）と、芯材（１１）に付着しないように拘束材（１２）に充填された充填材（１３）とを有する。【選択図】図１
