Abstract The present invention relates to a steel girder having an end-expanded protruding flange and a support concrete block, which forms an end-expanded protruding flange to protrude from both ends of a steel girder in a longitudinal direction by a predetermined length, and forms a support concrete block at an upper portion to allow the support concrete block to further protrude to the outside of a bridge support with respect to a longitudinal direction of a girder, starting from the bridge support for mounting the girder when the girder is mounted on an alternating structure such that installation of an elastic joint device is not required and self-weight of a protruding expanding part and a load of a vehicle wheel are not applied to a parapet wall; and to a method for constructing a jointless bridge using the same. According to an embodiment of the present invention, the steel girder comprises: an H-shaped body for forming an H-shaped cross section by including upper and lower flanges and a web for connecting central portions of the upper and lower flanges in a width direction; an end-expanded protruding flange bonded to protrude by a predetermined length to the outside from both ends of the H-shape body in a longitudinal direction by including a support part of a horizontal plate shape formed to be greater than the width of the upper flange by a predetermined width and a side surface part formed on an upper portion of the support part; and a support concrete block formed by a predetermined thickness only on the entire width or a partial width of an upper surface of the end-expanded protruding flange. 본 발명은 강거더의 길이방향 양단부에서 일정길이 돌출되도록 단부확장 돌출플랜지를 구성하고 상부에 받침 콘크리트 블럭을 형성되도록 하여 교대구조체에 거더 거치시에 거더를 거치하는 교량받침을 기점으로 거더 길이방향에 대해 교량받침의 외측으로 받침 콘크리트 블럭이 더 돌출되도록 함으로써 신축이음장치의 설치가 필요 없을 뿐만 아니라 돌출확장부의 자중과 차량 바퀴 하중이 흉벽에 작용되지 않도록 하는 단부확장 돌출플랜지와 받침 콘크리트 블럭을 갖는 강거더 및 이를 이용한 무조인트교량 시공방법에 관한 것이다. 본 발명의 단부확장 돌출플랜지와 받침 콘크리트 블럭을 갖는 강거더의 바람직한 일 실시예는 상부 플랜지와 하부 플랜지 및 상부 플랜지와 하부 플랜지의 폭방향 중앙부를 연결하는 웨브로 이루어져 H형 단면을 형성하는 H형 본체와; 상부 플랜지의 폭보다 일정 폭 크게 형성되는 수평판 형상의 받침부와 받침부에서 상부로 형성되는 측면부로 이루어져 H형 본체의 길이방향 양단부에서 각각 외측으로 일정 길이 돌출되도록 접합되는 단부확장 돌출플랜지와; 단부확장 돌출플랜지의 상부면의 전체 폭 또는 일부 폭에만 일정 두께로 형성되는 받침 콘크리트 블럭;을 포함하여 이루어진다.
AbstractList The present invention relates to a steel girder having an end-expanded protruding flange and a support concrete block, which forms an end-expanded protruding flange to protrude from both ends of a steel girder in a longitudinal direction by a predetermined length, and forms a support concrete block at an upper portion to allow the support concrete block to further protrude to the outside of a bridge support with respect to a longitudinal direction of a girder, starting from the bridge support for mounting the girder when the girder is mounted on an alternating structure such that installation of an elastic joint device is not required and self-weight of a protruding expanding part and a load of a vehicle wheel are not applied to a parapet wall; and to a method for constructing a jointless bridge using the same. According to an embodiment of the present invention, the steel girder comprises: an H-shaped body for forming an H-shaped cross section by including upper and lower flanges and a web for connecting central portions of the upper and lower flanges in a width direction; an end-expanded protruding flange bonded to protrude by a predetermined length to the outside from both ends of the H-shape body in a longitudinal direction by including a support part of a horizontal plate shape formed to be greater than the width of the upper flange by a predetermined width and a side surface part formed on an upper portion of the support part; and a support concrete block formed by a predetermined thickness only on the entire width or a partial width of an upper surface of the end-expanded protruding flange. 본 발명은 강거더의 길이방향 양단부에서 일정길이 돌출되도록 단부확장 돌출플랜지를 구성하고 상부에 받침 콘크리트 블럭을 형성되도록 하여 교대구조체에 거더 거치시에 거더를 거치하는 교량받침을 기점으로 거더 길이방향에 대해 교량받침의 외측으로 받침 콘크리트 블럭이 더 돌출되도록 함으로써 신축이음장치의 설치가 필요 없을 뿐만 아니라 돌출확장부의 자중과 차량 바퀴 하중이 흉벽에 작용되지 않도록 하는 단부확장 돌출플랜지와 받침 콘크리트 블럭을 갖는 강거더 및 이를 이용한 무조인트교량 시공방법에 관한 것이다. 본 발명의 단부확장 돌출플랜지와 받침 콘크리트 블럭을 갖는 강거더의 바람직한 일 실시예는 상부 플랜지와 하부 플랜지 및 상부 플랜지와 하부 플랜지의 폭방향 중앙부를 연결하는 웨브로 이루어져 H형 단면을 형성하는 H형 본체와; 상부 플랜지의 폭보다 일정 폭 크게 형성되는 수평판 형상의 받침부와 받침부에서 상부로 형성되는 측면부로 이루어져 H형 본체의 길이방향 양단부에서 각각 외측으로 일정 길이 돌출되도록 접합되는 단부확장 돌출플랜지와; 단부확장 돌출플랜지의 상부면의 전체 폭 또는 일부 폭에만 일정 두께로 형성되는 받침 콘크리트 블럭;을 포함하여 이루어진다.
