이들 도면에 도시된 바와 같이, 본 발명에 따른 강재와 철근콘크리트로 구성된 비합성 아치리브를 이용한 아치교 시공방법은 거푸집(10)을 제작하는 단계; 상기 거푸집(10)내에 철근(12)을 배근하는 단계; 상기 거푸집(10)내의 가운데에 강재(14)를 삽입 및 고정하는 단계; 상기 거푸집(10)내에 콘크리트(16)를 타설 및 양생시킨 후, 거푸집(10)을 탈형하여 아치리브(A)를 제작하는 단계; 상기 아치리브(A)를 보강거더(G)에 강결시키고, 상기 아치리브(A)와 보강거더(G)간에 수직으로 행거(H)를 조립 설치하고, 상기 행거(H)에 초기장력을 도입하여 아치교(B)를 시공하는 단계로 이루어진다.As shown in these drawings, the arch bridge construction method using a non-synthetic arch rib composed of steel and reinforced concrete according to the present invention comprises the steps of manufacturing the formwork (10); Reinforcing bar 12 in the formwork 10; Inserting and fixing the steel 14 in the center of the formwork 10; After pouring and curing concrete 16 in the formwork 10, demoulding the formwork 10 to produce an arch rib (A); The arch rib (A) is rigid to the reinforcement girder (G), the hanger (H) is assembled and installed vertically between the arch rib (A) and the reinforcement girder (G), and the initial tension is introduced into the hanger (H). By the step of constructing the arch bridge (B).

여기서, 상기 강재(14)를 삽입 및 고정하는 단계는 강재(14)를 비닐(18)로 피복한 상태로 거푸집(10)의 내측에 고정철물(20)로 고정 설치한다.Here, the step of inserting and fixing the steel 14 is fixed to the inside of the formwork 10 with the fixing iron 20 in a state in which the steel 14 is covered with a vinyl (18).

즉, 본 발명에 따른 강재와 철근콘크리트로 구성된 비합성 아치리브를 이용한 아치교 시공방법은 거푸집(10)을 제작하고, 상기 거푸집(10)내에 철근(12)을 배근하며, 상기 거푸집(10)내의 가운데에 강재(14)를 비닐(18)로 피복한 상태로 거푸집(10)의 내측에 고정철물(20)으로 고정 설치한 후, 상기 거푸집(10)내에 콘크리트(16)를 타설 및 양생시킨 후, 상기 거푸집(10)을 탈형하여 아치리브(A)를 제작한 후, 상기 아치리브(A)를 보강거더(G)에 강결시키고, 상기 아치리브(A)와 보강거더(G)간에 수직으로 행거(H)를 조립 설치하고, 상기 행거(H)에 초기장력을 도입하여 아치교(B)를 시공한다.That is, the arch bridge construction method using a non-synthetic arch rib composed of steel and reinforced concrete according to the present invention to produce a form (10), reinforce the reinforcing bars 12 in the form (10), in the form (10) After fixing the steel 14 in the center with the fixed metal 20 inside the formwork 10 in a state covered with a vinyl 18, after pouring and curing the concrete 16 in the formwork 10 After deforming the formwork (10) to produce an arch rib (A), the arch rib (A) is rigid to the reinforcement girder (G), and vertically between the arch rib (A) and the reinforcement girder (G). The hanger H is assembled and installed, and the arch bridge B is constructed by introducing an initial tension into the hanger H.

특히, 본 발명에 따른 강재와 철근콘크리트로 구성된 비합성 아치리브를 이용한 아치교 시공방법은 중소형 아치교(B)에 적용되는 아치리브(A)는 파이프 형상이나 박스형상으로 회전반경이 크므로 좌굴에 대해 유리하므로 적합한 형상이 된다.In particular, the arch bridge construction method using a non-synthetic arch rib composed of steel and reinforced concrete according to the present invention arch arch (A) applied to the small and medium arch bridge (B) is a pipe shape or box shape because the rotation radius is large for buckling As it is advantageous, it becomes a suitable shape.

상기 강재(14)는 주로 포물선 형상으로 제작되어 현장에서 조립연결을 하게 되는데 연직 포물선으로 거치하기 전에 아치리브(A)가 무응력 상태가 되도록 제작함과 동시에 역학적 거동이 특정한 경우에 대해 전단연결재를 강재(14)에 부착하지 않고 강재(14)와 철근콘크리트(12, 16)를 비합성으로 연결하여 아치리브(A)를 제작하고, 보강거더(G)에 연결하고, 행거(H)에 초기장력을 도입하여 아치교(B)를 시공한다.The steel 14 is mainly manufactured in a parabolic shape to be assembled and assembled in the field. The arch rib A is made to be in a stress-free state before being mounted in a vertical parabola and at the same time a shear connector is used for a specific case of mechanical behavior. Without attaching to the steel 14, the steel 14 and the reinforced concrete (12, 16) by connecting non-synthesized to produce the arch rib (A), connected to the reinforcement girder (G), the initial to the hanger (H) Introduce tension and construct arch bridge (B).

여기서, 상기 행거(H) 설치시 적절한 초기장력을 도입하여 시공하는 경우는 아치리브(A)에 고정하중에 의해 모멘트가 발생되지 않도록 초기장력을 결정할 수가 있고, 보강거더(G)의 아치리브(A) 대비 상대강성을 적절히 키우면, 활하중 및 기타 모든 외력에 대해서도 아치리브(A)에 인장응력을 배제시킬 수가 있다.Here, when installing the appropriate initial tension when installing the hanger (H), the initial tension can be determined so that the moment is not generated by the fixed load on the arch rib (A), the arch rib of the reinforcement girder (G) A) If the relative stiffness is properly increased, the tensile stress can be excluded from the arch rib (A) for live loads and all other external forces.

이 경우 강재(14) 단면과 콘크리트(16) 단면의 중립축을 일치시키면 콘크리트(16)와 강재(14) 사이에 전단류(shear flow)가 없어지므로, 전단연결재가 필요치 않게된다.In this case, matching the neutral axis of the cross section of the steel 14 and the cross section of the concrete 16 eliminates the shear flow between the concrete 16 and the steel 14, thus eliminating the need for a shear connector.

또한, 상기 강재(14)는 회전반경이 큰 파이프나 박스단면으로 구성되어, 그 표면을 콘크리트(16)로 피복함으로 압축응력만 받는 콘크리트(16) 피복은 균열없이 강재(14)의 부식을 방지하므로 별도의 유지관리 없이 내구성 있는 아치리브(A)가 될 수 있다.In addition, the steel 14 is composed of a pipe or a box cross section having a large radius of rotation, the concrete 16 is subjected only to the compressive stress by covering the surface with concrete 16 to prevent corrosion of the steel 14 without cracking Therefore, it can be a durable arch rib (A) without additional maintenance.

그리고, 시공의 공정도 단순화 되므로 공사비가 절감되는 작용효과도 기대된다.In addition, since the construction process is simplified, the effect of reducing the construction cost is also expected.
