Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a high-precision steel beam splicing device and a splicing method. Background Art

[0002] In the construction of mountain bridges, viaducts and other projects, the construction of bridge erection machines under high pier conditions is one of the commonly used construction methods. Steel beams are the preferred beam material in bridge erection machine construction due to their light weight, high strength, easy processing and time saving. Each steel beam is erected on the support above each span cap beam by a bridge erection machine. Therefore, the erection of steel beams is one of the key links in the construction of high pier bridges.

[0003] Unlike the erection of steel beams on straight lines, the erection of steel beams on small curvature ramps with high piers is extremely difficult and the position of the steel beams is difficult to adjust with the help of a bridge erection machine. Once the erection position of the steel beam deviates too much from the design, it will inevitably affect the stress of the steel beam and may even cause cracks in the steel beam, affecting the comfort and safety of subsequent driving.

[0004] At present, in the case of curved lines, the existing technology uses a bridge erection machine to adjust the position of the beam, which has many limitations and inconveniences: when the bridge erection machine adjusts the beam posture, it is necessary to adjust the position of the legs, offset the machine arm, etc., which is prone to problems such as axis deviation and elevation deviation of the beam erection. It is difficult to accurately erect the beam in place, and when the line curvature decreases (such as high-speed ramps) and the bridge piers increase in height, the difficulty of beam erection construction increases sharply. Therefore, a high-precision steel beam splicing device and splicing method are proposed, which has important practical engineering significance. Summary of the invention
