PURPOSE: A method for constructing is provided to increase an accurate construction and the easiness of a work by installing a winding problem of vertical curve and a bearing device before settling a continuous typed prestressed synthetic beam. CONSTITUTION: After a settling support is installed in the state rising a first point and a third point as a remained falling device of a second point of an existing construction method or the settling support is installed in the state rising the first point or the third point as two times of the remained falling device of the second point of the existing construction method in a construction method of a twp-span continuous typed prestressed synthetic beam, two beams are installed. After removing the settling support of both ends, the second point is risen as a pure fallen value of the existing construction method again. A bottom plate concrete of a negative moment section is poured and the pure fallen value is fallen again. Thereby a vertical curve of the final continuous typed prestressed synthetic beam is flattened.
