Abstract Research purposes:In recent years，with increase of construction of a variety of continuous beam and simply supported beam bridges，how to quickly，standardizedly and economically construct such kind of the bridges becomes the very important． Taking the bridge erecting machine used for the north bridge approach of the Taohuayu Yellow River bridge as an example，the study was done on the construction method for segmental assembling construction by using the assembled bridging machine in order to ensure the construction schedule and save the construction cost．

Research conclusions:The model was established to analyze the structure of the assembled bridge erecting machine．The analysis results showed that the structure of the bridge erecting machine could meet the construction requirements，and its stiffness was stronger than standard bridge erecting machine by about 1． 5 times． With full use of the existing member bars for the this bridge erecting machine，the investment in manufacturing new kind of member bars was much reduced and the cost was saved by 50% ． The bridge erecting machine runs on the slide board with the features of smooth running，easy operation，safety and reliability．It can provide the reference to similar works．

Key words： assembled bridge erecting machine structure design construction
