The invention provides a crane truss and a plant structure, the crane truss comprises an upper chord, a lower chord and diagonal web members, the lower chord is a box-shaped cross section, the lower chord of the box-shaped cross section comprises a lower chord box-shaped wall plate, an upper flange plate and a lower flange plate, the lower ends of the diagonal web members are connected to web member nodes of the lower chord, and the diagonal web members are connected to the upper flange plate and the lower flange plate. The web member node is provided with at least two vertical node plates extending along the lower chord box type wall plate; the upper flange plate is provided with a node groove, the vertical node plates are inserted into the node groove in a penetrating mode, the at least two vertical node plates are distributed at intervals, a node connecting cavity is formed between the at least two vertical node plates, and the ends of the diagonal web members extend into the node connecting cavity and are fixedly connected with the node connecting cavity. The technical problems that a large-span crane truss box type lower chord connecting joint is poor in bearing capacity and insufficient in anti-fatigue performance are solved.

    本发明提供了一种吊车桁架及厂房结构,该吊车桁架包括:上弦、下弦和斜腹杆,所述下弦为箱型截面,箱型截面的所述下弦包括下弦箱型壁板、上翼缘板和下翼缘板,所述斜腹杆的下端连接于所述下弦的腹杆节点,所述腹杆节点设置有沿下弦箱型壁板延伸的至少两个竖节点板;所述上翼缘板设置有节点槽,所述竖节点板穿插于所述节点槽,至少两个所述竖节点板间隔分布且两者之间设置有节点连接腔,所述斜腹杆的端部延伸至所述节点连接腔内且固接,解决了大跨度吊车桁架箱型下弦连接节点的承载能力较差,抗疲劳性能不足的技术问题。
