Abrégé
(EN)
The present invention relates to a steel structure including a pre-stressing bracket for improving load-carrying capacity and serviceability, and more particularly, to a steel structure including: a steel girder; a plurality of connecting brackets connected to the bottom surface of the steel girder, and spaced apart from one another; and a cover plate connected to the bottom surfaces of the connecting brackets. Accordingly, since the cover plate is installed regardless of the connecting portion of the steel girder, pre-stressing sections can be consecutively formed to improve the pre-stress effect. In addition, since the connecting brackets space the steel girder a constant distance from the cover plate, the second moment of area is increased to maximize area efficiency, thereby increasing the span of a bridge.

La présente invention se rapporte à une structure en acier comprenant un support de précontrainte afin d'améliorer la capacité de charge et la facilité d'entretien et, plus particulièrement, à une structure en acier comprenant : une poutre en acier ; une pluralité de supports de raccordement raccordés à la surface inférieure de la poutre en acier et espacés les uns des autres ; et une plaque de couverture raccordée aux surfaces inférieures des supports de raccordement. Par conséquent, puisque la plaque de couverture est installée sans se soucier de la partie de raccordement de la poutre en acier, des sections de précontrainte peuvent être formées consécutivement pour améliorer l'effet de précontrainte. De plus, puisque les supports de raccordement écartent la poutre en acier de la plaque de couverture sur une distance constante, le second moment d'aire est accru afin de maximiser l'efficacité surfacique, ce qui permet d'augmenter la travée d'un pont.

본 발명은 내하성능 및 사용성능의 개선을 위한 프리스트레싱 브라켓이 구비된 강구조물에 관한 것으로, 더욱 상세하게는 강거더와, 상기 강거더 하면부에 연결되고, 상호 이격 배열된 연결브라켓과, 상기 각 연결브라켓 하면부에 연결된 커버플레이트를 포함하여 이루어져, 커버플레이트의 설치 시 강거더의 연결 부분에 의한 제한을 받지 않게 되어 프리스트레싱 구간을 연속적으로 도입할 수 있어 프리스트레스 효과를 증가시킬 수 있고, 아울러 연결브라켓이 강거더와 커버플레이트를 일정한 간격으로 이격시킴으로써 단면 2차 모멘트의 증대와, 이에 의한 단면효율 극대화로 교량의 장지간화를 이룰 수 있는 내하성능 및 사용성능의 개선을 위한 프리스트레싱 브라켓이 구비된 강구조물을 제안하고자 한다.
