TEMPORARY BRIDGE HAVING THE STRUCTURE SYSTEM COMBINING GIRDER WITH DECKING PANNEL AND PRESTRESSING THE SUPPORTING POINT AND METHOD FOR CONSTRUCTING THEREOF

摘要

The present invention relates to a temporary bridge having an integrated structure of a temporary girder and a decking panel and a prestressing structure for a point part and a construction method thereof. The temporary bridge comprises: multiple temporary vents which are arranged to be separated from each other and have an enlarged top width; multiple temporary girders which are placed on the temporary vents; support parts which are formed between the temporary vents and the temporary girders; vertical prestressing steel members which vertically tense and fix the point parts of the temporary girders to the temporary vents; and multiple decking panels which are formed on the top of the temporary girders. Thus, the present invention enables the long-span construction of the temporary bridge as the cross-section efficiency of the temporary girders is improved, and improves the bearing capacity of the temporary girders.
