| description | A construction method for integrally hoisting a large-size multi-edge-and-corner overhanging truss is disclosed. Integral assembling of a steel pipe truss is conducted on site, and integral hoisting is conducted after assembling is completed; the truss is connected with three welding positions in a butt-joint mode and then is welded firmly; two 500 t all-terrain cranes and a 350 t all-terrain crane are adopted to hoist the whole truss simultaneously, and step-by-step hoisting is conducted from south to north; the truss is totally provided with three main stress support joints which are all fixed by adopting butt welding, a third calibration point support is located at the top of the truss, a welded ball joint at the position of the third calibration point is a support point of a steel rainshed grid frame actually, a first calibration point support and a second calibration point support are located on both the left and right sides of the bottom of the truss correspondingly, and the first calibration point supp |
