Description

가압정착시스템을 이용한 구조용 거더{Structural girder using a loading anchor system for girder}Structural girder using pressure fixing system {Structural girder using a loading anchor system for girder}

본 발명은 프리텐션/포스트텐션 방식의 가압정착시스템을 이용하여 압축부에 인장응력을 도입하여 이를 각종 도로교, 철도교 및 건축물의 빔에 이용할 수 있는 가압정착시스템을 이용한 구조용 거더에 관한 것이다.     The present invention relates to a structural girder using a pressure fixing system that can be used for the beams of various road bridges, railway bridges and buildings by introducing a tensile stress in the compression section using a pressure fixing system of a pretension / post tension method.

종래의 PSC빔은 인장용 PC강재를 이용하여 고정하중 및 공용하중에 의한 휨모멘트로 발생 하는 인장응력을 감소시키기 위하여 빔하단에 압축응력을 도입한 구조용 빔이다. 이러한 PSC 빔은 하부에 과도한 압축응력을 도입시 상연에 허용압축응력을 초과할 경우 단면을 증가시켜 형고를 증가시키거나 하중분담을 감소시키기 위하여 거더의 본수를 증가시키는 방법을 적용하였다.     Conventional PSC beam is a structural beam that uses a compressive stress at the bottom of the beam in order to reduce the tensile stress caused by the bending moment due to the fixed load and the common load by using the PC steel for tension. When the PSC beam is subjected to excessive compressive stress at the bottom, it increases the cross section when the allowable compressive stress is exceeded in the upper stage, and increases the number of girder heads in order to increase the mold height or reduce the load sharing.

하지만 이러한 방법은 거더의 제작비를 증가시킬 뿐 아니라 거더의 자중을 증가시키고 공사비를 증가시키며 내진에도 상당히 불리하게 작용하는 문제점이 지적되었다.However, it was pointed out that this method not only increases the manufacturing cost of the girder, but also increases the weight of the girder, increases the construction cost, and significantly adversely affects the earthquake.

이러한 이유로 교량의 설계시 시방규정에 따라야 하며 이러한 시방규정의 허용압축응력 이내로 응력을 규정하고 있어, 형고의 증가없이 압축응력이 과도하게 발생하는 부위에 이를 분담하도록 압축용 PC강재를 적용하여 응력을 분담하도록 하는 메커니즘을 이용하는 것이다. For this reason, when designing bridges, it is necessary to follow the specification regulations, and stresses are defined within the allowable compressive stresses of these specifications, and the stress is applied by applying PC steel for compression so as to share them in the areas where excessive compressive stress occurs without increasing the mold height. Is to use a sharing mechanism.

본 발명이 이루고자하는 기술적 과제는 거더단면에 발생하는 과도한 압축응력을 효과적으로 대응할 수 있도록 압축용 PC강재를 배치하여 인장응력을 도입할 수 있도록 가압정착시스템을 제공하여 거더를 제작, 시공하는데 있다.  The technical problem to be achieved by the present invention is to provide a pressure fixing system to introduce a tensile stress by arranging the PC steel for compression to effectively cope with the excessive compressive stress generated in the girder cross section to manufacture and construct a girder.

상술한 과제를 해결하기 위하여 본 발명은,       In order to solve the above problems, the present invention,

거더의 압축단면에 인장응력을 효과적으로 도입시킴으로서 경제적인 구조용 거더을 제작할 수 있는 가압정착시스템(110,170,180)을 제공하는 것이다. 따라서 거더단면에 발생하는 과도한 압축응력을 상쇄시킬 수 있는 인장응력을 도입할 수 있도록 단면의 증가와 거더 본 수의 증가없이 고정하중과 공용하중에 의하여 발생하는 압축응력을 시방규정에 따른 허용압축응력 이내로 감소시켜 경제적인 거더를 제작할 수 있는 가압정착시스템을 이용하여 제작된 구조용 거더이다. By effectively introducing the tensile stress in the compression section of the girder to provide a pressure fixing system (110, 170, 180) that can produce an economical structural girder. Therefore, in order to introduce tensile stress that can offset excessive compressive stress generated on the girder section, the compressive stress generated by the fixed load and the common load without increasing the number of sections and the number of girders is allowed. It is a structural girder manufactured by using a pressure fixing system that can be reduced to within an economical girder.

상술한 바와 같이 본 발명에 의하면,거더에 설치된 인장, 압축용 PC강재(140)를 인장, 압축단에 동시에 적용하여 형고가 제한되거나 단면의 증가 없이 내하력을 증강시키고, 형고감소 효과로 인한 공사비 절감을 기대할 수 있으며 상부에서의 작업공정을 단순화시켜 시공성 개선과 전도에 대한 위험요소를 대폭 감소시킬 수 있다.      According to the present invention as described above, by applying the tension, compression PC steel 140 installed in the girder at the same time to the tension, compression stage to increase the load-bearing capacity without limit or increase in cross-section, construction cost reduction due to the high mold reduction effect It can be expected that the work process at the top can be simplified, greatly improving the workability and reducing the risk of overturning.
