The present invention is a method of applying a pre-flex load and prestress in a pre-tension method, and more particularly is a method of applying a pre-flex load and prestress in a pre-tension method, in which a required amount of pre-flex load may be applied by minimized equipment or without any loading equipment for applying pre-flex load to a steel in process of manufacturing a pre-flex steel composite girder. The present invention is a method of applying a pre-flex load to a pre-flex steel composite girder including steels and concrete or a steel composite beam, which includes: a first connecting step of connecting a first connecting member with one end of a main body of steel positioned in one direction to transmit moment and a shearing force; a setting step of setting the main body connected in the first connecting step and both ends of the first connecting member in supporting members ; a constructing step of placing and curing concrete to a lower flange of the main body in a state where the main body and the first connecting member are set in the supporting members; and a separation step of separating the first connecting member and the main body from each other after the constructing step of placing and curing concrete. |
