PURPOSE: A concrete curing apparatus of a girder and a manufacturing method of a girder using the same are provided to shorten curing time by heating concrete, which is poured in a mold, in a short time once being installed. CONSTITUTION: A concrete curing apparatus of a girder includes a form and a steam supplying pipe(130). The form includes a form board and at least one closed section member(113,114). The closed section members are extended and arranged on the exterior of the form board along the one-way direction in one line or more. The close section members have a lot of vapor efflux holes, which are toward the surface of the form board and are spaced from each other. The steam supplying pipe is mounted at the entrance of the closed section members of the form, and supplies high temperature steam into the closed section members. The high temperature steam, which is supplied from the steam supplying pipe, is supplied along the closed section members and is discharged through the steam efflux holes, such that the form board is heated. |
