PSC PSC PRE-TENSION PSC GIRDER MANUFACTURING METHOD AND PRE-TENSION PSC GIRDER MANUFACTURING SYSTEM
Disclosed is a pre-tension PSC girder manufacturing method. According to the present invention, the pre-tension PSC girder manufacturing method includes: a step of installing a bottom mold and a reaction stand so as to correspond to a length of a pre-tension girder to be manufactured and arranging a plurality of strands on an upper portion of the bottom mold; a first girder manufacturing step of applying first pre-tension force capable of resisting the maximum bending moment by self-weight and a live load to the strand to form a central portion of the pre-tension girder; and an nth girder manufacturing step of being provided on both side surfaces of a first girder and formed by applying nth pre-tension force lower than the first pre-tension force.
프리텐션 PSC 거더 제작방법이 개시된다. 본 발명에 따른 프리텐션 PSC 거더 제작방법은, 제작될 프리텐션 거더의 길이에 대응되도록 저면 거푸집과 반력대를 설치하고, 강연선을 상기 저면 거푸집의 상부에 다수 배치하는 단계, 자중 및 활하중에 의한 최대 휨 모멘트에 저항할 수 있는 제1 프리텐션력을 강연선에 가하여 프리텐션 거더의 중앙부를 형성하는 제1 거더 제작단계, 제1 거더의 양측면에 마련되며, 제1 프리텐션력 보다 저감된 제n 프리텐션력을 가하여 형성되는 제n 거더 제작단계를 포함한다.
