PURPOSE: An end support apparatus using a cross-shaped tendon anchorage plate, a prestressed concrete beam, and a construction method using the same are provided to effectively support an anchor plate and to easily pour concrete to form a lower flange. CONSTITUTION: An end support apparatus using a cross-shaped tendon anchorage plate comprises a lower plate(310), an inner intermediate reinforcement plate(320), a cross-shaped anchor plate support plate(350), and an anchor plate(340). The inner intermediate reinforcement plate is formed on the top center of the lower plate and places an I-shaped steel(100) on the top in order to touch the bottom of a lower flange(130). The cross-shaped anchor plate support plate comprises a vertical plate(351) and a horizontal plate(352) to be arranged in both sides of the intermediate reinforcement plate. The anchor plate is supported in the front side of the cross-shaped anchor plate support plate, the lower flange, and the inner intermediate reinforcement plate; is installed in the top of the lower plate; and settles after a tendon(220) is tense. |
