상기 비합성복합강관기둥은 강관의 상하단부의 일정높이에 보강커버플레이트를 설치하고, 상기 보강커버플레이트가 설치된 강관내부에 일정한 간격을 두고 전단연결재를 설치하고, 강관내부에 수직철근과 띠철근으로 조립된 철근기둥조립체를 삽입한 다음, 강관내부를 무수축콘크리트로 타설충전하여 무수축철근콘크리트가 설치되도록 하여 강관내에 설치된 무수축철근콘크리트와 강관을 일정한 범위에 걸쳐 설치된 강관 상하단부의 강관내부에 설치된 전단연결재에 의하여 결합, 합성시키고, 그 이외의 부분인 강관의 중앙부에서는 강관과 무수축철근콘크리트와 결합시키지 않은 비합성상태로 시공한 것이다.The non-composite composite steel pipe column is provided with a reinforcement cover plate at a predetermined height of the upper and lower ends of the steel pipe, a shear connection member is installed at regular intervals inside the steel pipe in which the reinforcement cover plate is installed, and the vertical reinforcing bars and the band reinforcing bar inside the steel pipe. After inserting the assembled reinforcement column assembly, the inside of the steel pipe is filled with non-contraction concrete so that the non-contraction reinforcement concrete is installed so that the non-contraction reinforcement concrete and the steel pipe installed in the steel pipe are installed in the steel pipe at the upper and lower ends of the steel pipe. It is bonded and synthesized by the installed shear connector, and the other part is constructed in a non-synthetic state in which the steel pipe and the non-reinforced concrete are not bonded.

본 발명의 목적은 강관의 상하단부 내부에 전단연결재를 설치하여 강관내부에 삽입된 철근기둥조립체에 타설된 무수축콘크리트에 의하여 형성된 무수축철근콘크리트의 상하단부와 강관이 상호연결된 합성으로 하고, 강관의 중앙부는 연결이 안된 비합성상태로 시공한 비합성복합강관기둥을 압축부재인 사장교파이론기둥으로 사용하여 교량구조역학적인 면에서 효율성이 있으면서 시공성이 향상되어 이로인하여 공사비가 절감되는 비합성복합강관기둥의 시공방법을 제공하는데 있다.An object of the present invention is to install a shear connector in the upper and lower ends of the steel pipe to be a composite of the upper and lower ends and the steel pipe of the non-contracted reinforced concrete formed by the non-concrete concrete placed in the reinforcement pillar assembly inserted into the steel pipe, the steel pipe The non-composite composite steel pipe pillar, which is constructed in an unsynthesized state, is used as a cable-stayed cable-pylon pillar, which is a compression member, so that the construction efficiency is improved in terms of bridge structural dynamics, thereby reducing construction costs. It is to provide a method of constructing a column.

일반적으로 사장교의 주탑인 사장교파이론기둥은 정확히 수직을 유지하면서 기둥의 직진성이 요구되는 시공이 매우 정밀하게 진행되어야 하는 기둥인 것이다. In general, the cable-stayed pylon pillar, which is the main tower of the cable-stayed bridge, is a column whose construction requires very precise construction while maintaining the verticality.

상기와 같이 시공의 정밀성이 요구되는 사장교파이론기둥을 강관의 내부에 속채움콘크리트로 타설한 강관기둥을 사용하는 것이 시공성 및 경제적으로 효율성이 있으나, 강관과 콘크리트를 상호연결되는 합성으로 하기 위하여는 강관내부 전체면에 걸쳐 전단연결재를 설치하여야 하나 강관내부 전체에 걸쳐 돌출된 내부연결재의 설치가 매우 곤란한 관계로 인하여 제작이 매우 번거로운 점, 특히 소규모의 사장교파이론기둥인 경우에는 전혀 시공이 불가능한 점이 문제점으로 대두되어 왔다.As mentioned above, although the use of a steel pipe pillar in which a cable-stayed pylon column is required to be placed inside the steel pipe is required for construction accuracy, it is efficient in construction and economical, but in order to make the composite of the steel pipe and concrete interconnected Shear connector should be installed over the entire inner surface, but it is very cumbersome to manufacture because of the very difficult installation of the inner connector that protrudes throughout the inside of the steel pipe, especially in the case of small cable-stayed pylon pillars. It has been emerging.

본 발명은 상기와 같은 문제점을 개선하기 위하여 제안된 발명으로서, 본 발명은 번거로운 강관 내부 전체면에 걸쳐 설치되는 전단연결재의 설치를 생략하고, 강관의 양단부에서만 강관과 철근콘크리트기둥이 상호 연결되도록 하고, 강관의 중앙부에서는 상호 연결되지 않은 비합성의 상태로 하여 하중이 작용될때 강관과 강관내부에 설치된 무수축철근콘크리트가 각각 분담하여 저항하도록 하는 비합성복합강관기둥시공방법의 제공에 있다. The present invention has been proposed in order to improve the above problems, the present invention omits the installation of the shear connecting material is installed over the entire inner surface of the cumbersome steel pipe, so that the steel pipe and reinforced concrete pillars only interconnected at both ends of the steel pipe In the center of the steel pipe, there is provided a method of constructing a non-composite composite steel pipe column in which the non-composite reinforced concrete installed inside the steel pipe and the non-composite reinforced concrete are respectively shared and resisted when the load is applied to the non-synthetic state.

또한, 휨부재인 경우에는 각각의 부재가 상호 연결된 합성부재로 제작시공되어야 작용하는 하중의 휨모멘트에 저항할 수 있어 구조역학적으로 문제가 발생되지 않으나, 본 발명과 같이 기둥부재는 수직의 힘인 압축력에 주로 저항하는 부재로서, 상기 휨부재와 달리 부재상호간에 연결되지 않은 비합성상태의 부재를 이용하여도 구조역학적으로 전혀 문제가 되지 않은 즉, 외력에 대하여 비합성상태에서 각 각의 부재의 재료의 특성에 따라 일체적으로 작용하게되어 구조적인 취약점이 전혀발생하지 않는 점을 이용하여 사장교파이론기둥에 비합성복합강관기둥을 사용하도록 하는 시공방법을 제공하기 위함이다.In addition, in the case of the bending member, each member must be constructed with interconnected composite members to resist the bending moment of the load to be applied, so structural problems do not occur, but the column member is a compressive force that is a vertical force as in the present invention. It is a member that mainly resists, and unlike the bending member, even if a member of a non-synthetic state is not connected between members, there is no structural problem at all, that is, the material of each member in a non-synthetic state against external force. It is to provide a construction method that uses non-composite composite steel pipe pillars for cable-stayed pylon pillars by taking advantage of the fact that structural weakness does not occur at all.
