The invention provides a multi-jig-frame assembled steel box girder construction auxiliary device and a construction method. The device comprises a segmented steel box girder, a modeling device and anon-contact three-dimensional scanning device. The non-contact three-dimensional scanning device performs three-dimensional scanning on the boundary dimension of the steel box girder assembled by subjig frames, processing the point cloud data after three-dimensional scanning, generating a 3D model, comparing the 3D model with a design model, finding out a deviation, comparing the deviation with astandard or design allowable deviation, and trimming a part exceeding the standard or design allowable deviation. By means of the device and the method, the manufacturing period of the ultra-large steel box girder is greatly shortened, the construction progress and precision are effectively improved, and the construction cost is reduced.
Description
technical field [0001] The invention relates to the technical field of super-large steel structure box girder construction, in particular to a construction device and a construction method for a steel box girder assembled with multiple tire frames using a non-contact three-dimensional scanning technology. Background technique [0002] With the development of the city, the number of vehicles in the city has increased significantly, and the reasons such as the limited terrain in the city make the crossing between roads and bridges inevitable. Super-large steel box girder bridges have been widely used in municipal construction and reconstruction projects in recent years because of their light weight, high strength, fast construction speed, and strong environmental protection. Super-large steel box girder bridges cannot be constructed on the same final assembly frame due to the limitation of the construction site due to their ultra-long and ultra-wide. In order to eliminate the...
