Abstract
본 발명은 프리캐스트 콘크리트 들보의 설치공법에 관한 것으로써, 들보의 자중에 의한 휨모멘트가 이웃한 들보로 분배되도록 함으로써 휨모멘트의 절대값을 작게할 목적으로 일련의 기등위에 걸쳐 재치된 다수개의 프리캐스트 콘크리트 들보의 중앙부에 상향의 힘을 가하여 위로 휘어지게 한 상태에서 들보의 단부 사이의 공간에 콘크리트를 타설하여 경화시키고 들보의 윗면에 설치한 돌기의 구멍을 통해 인장강재를 삽입하여 이것을 인장함과 동시에 상향의 힘을 감소시켜 인장이 완료될때 상향의 힘을 소거하고 인장강재를 정착시키는 것을 특징으로 하는 공법으로서 들보의 자중에 의한 휨모멘트의 절대값이 감소되어 들보의 내하력이 증가되는 효과가 있다.The present invention relates to a method for installing precast concrete beams, in which a plurality of pre-positions are placed over a series of lamps for the purpose of reducing the absolute value of the bending moment by allowing the bending moment due to the weight of the beam to be distributed to neighboring beams. The concrete is placed in the space between the ends of the beams with the upward force applied to the center of the cast concrete beams, and the concrete is placed in the space between the ends of the beams, and the tensile steel is inserted through the holes of the projections installed on the beams. At the same time, the method is characterized by eliminating the upward force and fixing the tensile steel when the tension is completed by reducing the upward force, thereby reducing the absolute value of the bending moment due to the weight of the beam, thereby increasing the load capacity of the beam. .
