The invention discloses large-span combined overweight eccentric slope angle steel structure integral synchronous jacking equipment. The large-span combined overweight eccentric slope angle steel structure integral synchronous jacking equipment includes a plurality of jacking units, and each jacking unit includes a cross joist and a jacking frame which are arranged coaxially from top to bottom insequence. The jacking frames are jacked by jacks. The jacking frames each include a jacking bracket, initial joints, multi-level standard joints and a base which are arranged coaxially from top to bottom in sequence. A jacking ball bracket is disposed at the top of each jacking bracket, and a hemispherical hinge support matched with the corresponding jacking ball bracket is arranged at the bottomof each cross joist. Net rack upper chord ball brackets fixedly connected with the corresponding cross joist are arranged above the cantilevered ends of each cross joist. The height of the bottom surfaces of the initial joints of the jacking frames of all the jacking units from the floor is the same, and the top surfaces are leveled with the slope of net racks. The jacking frames are combined witha combined steel structure in a pulling mode through undercling cable wind ropes, and the combined steel structure is combined with jacking foundations in a pulling mode through in-position cable wind rope. The large-span combined overweight eccentric slope angle steel structure integral synchronous jacking equipment can safely and reliably realize the integral synchronous lifting of the combinedsteel structure, and high-place operation can be greatly reduced.
