Assembled truss for plant construction

The utility model belongs to the field of construction of standard steel structure plant buildings, and provides an assembled truss for plant construction. The assembled truss comprises a plurality of truss splicing units and truss end support sections, wherein the truss splicing units are positioned at the middle part, and are connected in a splicing way; the truss end support sections are positioned at the two ends; every two adjacent truss splicing units are connected through high-strength bolts and the truss splicing units and the truss end support sections are connected through high-strength bolts; running devices matched with plant crane rails are arranged on the outer end parts of the truss end support sections. According to the assembled truss, equipment can move more conveniently and rapidly, and a large amount of time is saved; meanwhile, the lower space of a plant is not occupied, so that smooth construction is facilitated, and construction materials can be conveniently transferred and stacked; the height of a construction platform can be reasonably adjusted to facilitate construction.
