Zusammenfassung:The utility model belongs to the technical field of light steel roof trusses. The utility model relates to a roof truss, in particular to a combined light-steel roof truss. An existing crane is largein investment of manual installation cost when hoisting a light steel roof truss. Meanwhile, the light steel roof truss is hoisted at a specified position; installation structure is too simple, the stability of the whole building is influenced. Proposed now is the following scheme, the device comprises a trapezoidal frame placed at the tops of two wall columns, a rectangular frame is arranged in the trapezoidal frame; two inclined supporting rods which are symmetrically arranged are fixedly mounted on each of the two sides of the rectangular frame; the other end of the inclined supporting rodis fixedly connected with the inner side of the trapezoidal frame; the light steel roof truss is easy to operate, the arranged hoisting structure can reduce swinging of the crane when the crane hoiststhe light steel roof truss
