PRESTRESSED CONCRETE GIRDER HAVING REINFORCING MEMBER AND THE CONSTRUCTION METHOD THEREOF
The present invention relates to a steel composite prestressed girder and a construction method using the same. According to the present invention, the steel composite prestressed girder includes: a main body concrete (110) comprising an upper flange (111) a web (112), and a lower flange (113); a reinforcing bar (120) installed in the main body concrete (110); and a T-shaped reinforcing member (130) connected to the upper part of the upper flange (111) and installed in the front and rear directions of the main body concrete (110). The reinforcing bar (120) includes: multiple main reinforcing bars (121) installed in the front and rear directions; and multiple shearing bars (122) installed along a transverse section of the main body concrete (110) by crossing the main reinforcing bar (121) and installed at intervals in the longitudinal direction. The reinforcing member (130) includes a vertical reinforcing member (131) and a horizontal reinforcing member (132), and the vertical reinforcing member (131) includes: an upper protrusion unit (131a) protruding to the upper side of the upper flange (111); and a lower embedment unit (131b) embedded in the upper flange (111). A shearing bar connection hole (133) which the shearing bar (122) passes through is formed in the embedment unit (131b) in the front and rear directions at intervals. The T-shaped reinforcing member (130) is embedded into the main body concrete (110) by being connected to the shearing bar (122), so a connection force of the reinforcing member and the main body concrete (110) is excellent. Also, the lower embedment unit (131b) embedded in the main body concrete (110) is a structure in which the vertical reinforcing member is embedded as shown in figure 5. So, the concrete is completely filled in a mold when the concrete of the main body concrete is placed in the mold.
본 발명에 의한 강합성 프리스트레스트 거더는 상부플랜지(111), 복부(112), 하부플랜지로(113)로 형성되는 본체 콘크리트(110); 본체 콘크리트(110)의 내부에 설치되는 철근(120); 상부플랜지(111)의 상부에 결합되어 본체 콘크리트(110)의 전후방향을 따라 설치되는 T형 구조의 보강재(130);를 포함하되, 철근(120)은 전후방향을 따라 설치되는 복수의 주철근(121); 주철근(121)과 교차 되어 본체 콘크리트(110)의 횡단면을 따라 설치됨과 아울러, 길이방향을 따라 상호 이격되어 복수로 설치되는 전단철근(122);을 포함하고, 보강재(130)는 세로보강재(131)와 가로보강재(132)를 포함하되, 세로보강재(131)는 상부플랜지(111)의 상측으로 돌출되는 상측 돌출부(131a); 상부플랜지(111)에 매립되는 하부 매립부(131b);를 포함하고 매립부(131b)에는 전후방향을 따라 상호 간격을 두고 전단철근(122)이 관통되어 설치되는 전단철근결합홀(133)이 형성된다. 이 경우, T형 구조의 보강재(130)는 전단철근(122)과 결합되어 본체 콘크리트(110)에 매립되기 때문에 보강재와 본체 콘크리트(110)의 결합력이 우수하다. 또한, 본체 콘크리트(110)에 매립되는 하부 매립부(131b)는 도5와 같이 세로 보강재가 매립되는 구조이기 때문에 본체 콘크리트의 콘크리트 타설시 거푸집 내부에 콘크리트 충진이 완벽하게 이루어진다.
