Large-span deformed steel truss structure module space assembly precision control method

The invention relates to the technical field of large-span deformed steel truss steel structure construction, and particularly provides a large-span deformed steel truss structure module space assembly precision control method which comprises the following steps: during construction, in order to dynamically correct errors among modules, establishing a space model of an overall structure by utilizing three-dimensional modeling software according to a construction blueprint; the overall structure is divided into module units, after measurement key points are determined and three-dimensional measurement coordinate conversion is completed, an assembling jig frame is established according to relative coordinates of the ground and an actual butt joint value of a previous module, and the accuracy of coordinates of supporting points of the assembling jig frame is guaranteed. During hoisting, a hoisting temporary supporting jig frame is arranged, the precision and stability of structure installation are guaranteed, an
