The invention provides a large-span steel truss which comprises a left building body and an adjusting device, a right building body is arranged on one side of the left building body, a steel truss body is arranged on the sides, close to each other, of the left building body and the right building body, steel truss plates are welded to the two sides of the steel truss body, and steel strands are arranged at the upper ends of the steel truss plates; supporting frames are fixedly connected to the upper end of the left building body and the upper end of the right building body, supporting plates are fixedly connected to the bottom ends of the supporting frames, and hydraulic lifters are arranged at one ends of the supporting frames. The problems that when a steel truss on a corridor is lifted and hoisted, the steel truss needs to be fixed and limited through a steel strand so as to be lifted, and due to the fact that the connection stability of the steel strand and a temporary lifting tool is low, the steel truss is prone to falling off are solved; therefore, the problem that the whole steel truss cannot be accurately butted and mounted is solved.

    本发明提供一种大跨度钢桁架,包括左建筑体和调节装置,所述左建筑体的一侧设置有右建筑体,所述左建筑体与右建筑体彼此靠近的一侧设置有钢桁架体,所述钢桁架体的两侧焊接有钢桁板,所述钢桁板的上端设置有钢绞线,所述左建筑体与右建筑体的上端均固定连接有支撑架,所述支撑架的底端固定连接有支撑板,所述支撑架的一端设置有液压提升器。本发明解决了在对连廊上的钢桁架进行提升吊装时,将会需要通过钢绞线对钢桁架进行固定限位从而进行提升,由于钢绞线与临时吊具的连接稳定性较低,从而容易发生钢桁架脱落的情况,进而导致整个钢桁架无法完成准确对接安装的问题。
