이에 본 발명은 다른 실시예로서, 내측판과 마주보는 외측판의 면상에 원기둥형(또는 원뿔형, 각기둥형 등)의 조인트 아암이 형성되어 내측판의 바깥에서 타이볼트로 하여금 간단히 조립할 수 있도록 함으로써, 타이로드(Tie Rod)의 사용을 생략할 수 있는 특징이 있다.In another embodiment, the present invention is a cylindrical (or conical, prismatic, etc.) joint arm is formed on the surface of the outer plate facing the inner plate to allow the tie bolts to be easily assembled outside the inner plate, The use of tie rods can be omitted.
또한, 본 발명은 타이로드 연결구조에 비하여 구조적으로 안정성을 확보함은 물론 조인트 아암을 갖는 외측판은 제작시 몰드 탈형 구조가 제거식으로 형성되어 다양한 형상의 조인트 아암을 확보할 수 있도록 하는 특징이 있다.In addition, the present invention is structurally secured as compared to the tie rod connecting structure, as well as the outer plate having a joint arm is characterized in that the mold release structure is formed in the removable form when manufacturing to ensure a joint arm of various shapes have.
또한, 본 발명의 조인트 아암에 형성된 체결구는 암나사가 형성되어 이웃한 타이볼트와 체결되도록 하되, 상기 체결구의 외주면에는 철선이 결합되어 힘 전달에 의한 구조 강성이 보강되도록 하는 특징이 있다.In addition, the fastener formed on the joint arm of the present invention is a female thread is formed to be fastened to the neighboring tie bolts, the outer peripheral surface of the fastener is characterized in that the steel wire is coupled to reinforce the structural rigidity by force transmission.
또한, 본 발명은 내외벽체간 조립시 다수개의 인서트, U자형 조인트, 돌출 블럭, 수직 및 수평철근의 합성 구조로 인해 합성력이 배가되어 구조의 강성이 현저하게 개선되는 특징이 있다.In addition, the present invention is characterized in that the stiffness of the structure is remarkably improved due to the doubled composite force due to the composite structure of a plurality of inserts, U-shaped joints, protruding blocks, vertical and horizontal reinforcement when assembling the inner and outer walls.
아울러, 본 발명은 복수의 PC 판넬(내,외측판) 자체가 거푸집 역활을 수행하도록 하여 종전의 목재 거푸집 시공에 비해 구조의 시공 높이 제한을 받지 않도록 하는 것에 특징이 있다.In addition, the present invention is characterized in that the plurality of PC panels (inner and outer plates) itself to form a role so as not to be limited in construction height of the structure compared to the previous wooden formwork.
일반적으로 공동구는 용수나 배수용의 수로가 도로, 철도, 제방 등의 아래에 매설되거나 전선로, 통신선로, 수도관, 열수송관, 중수도관, 쓰레기 수송관, 가스관, 하수도관 등 여러 가지 시설물을 도로 지하에 공동으로 매설하기 위하여 설치되는 것으로, 종래에는 현장에서 콘크리트를 타설 및 양생하는 방법으로 고동구의 시공이 이루어졌으나, 최근에는 공기 단축 및 경제적 시공을 위해 공장에서 미리 제작된 프리캐스트 구조물을 현장으로 운반하여 조립하는 것으로 대체되고 있는 실정이다.In general, common areas are water or drainage channels buried beneath roads, railways, and embankments, or various facilities such as electric lines, communication lines, water pipes, heat transport pipes, heavy water pipes, garbage transport pipes, gas pipes, and sewer pipes. It is installed to be buried underground, and in the past, the construction of Kodong-gu was done by placing and curing concrete in the field, but recently, precast structures pre-fabricated in the factory for shortening the air and economic construction The situation is being replaced by transporting and assembling.
이러한 프리캐스트 공법의 공동구는 시공속도가 빠르며 시공 후 즉시 되메우기를 할 수 있어 공사할 때 야기되는 시민불편사항, 교통 흐름의 방해, 불필요한 시간낭비 등의 문제를 해결할 수 있으므로 복잡한 도심지 공사에 효과적이며, 철저한 품질관리에 의해 공장에서 생산되므로 품질이 균일하고, 고강도 콘크리트를 사용하므로 구조체의 수밀성과 내구성을 증진시킬 수 있는 등 여러 가지 장점을 가지고 있다.The precast construction of the precast construction method is fast for construction and can be backfilled immediately after construction, which can solve problems such as civil inconvenience caused by construction, disruption of traffic flow, and unnecessary waste of time. Since it is produced at the factory by thorough quality control, the quality is uniform, and high strength concrete is used so that it can improve the watertightness and durability of the structure.
이를 보다 자세히 설명하면 프리캐스트 공동구가 설치될 장소에 터파기 및 기초 지반 정리작업을 한 후, 기초콘크리트를 타설한다. To explain this in more detail, after digging and foundation ground cleaning work in the place where the precast cavity is to be installed, the foundation concrete is poured.
이에, 타설된 기초콘크리트가 양생되면 프리캐스트 콘크리트 부재 즉, 벽체와 슬래브를 현장으로 운반하여 조립함으로써 시공을 완료하게 된다.Thus, when the foundation concrete is poured, the precast concrete member, that is, the wall and the slab is transported to the site to complete the construction.
그러나, 상기와 같은 종래의 시공방법은 통상 한 장으로 기립되는 피씨 벽에 의해 지중의 수분이 공동구 내부로 유입되어 통신케이블이나 전력케이블을 손상시키는 문제점이 있었다.However, the conventional construction method as described above has a problem of damaging the communication cable or the power cable due to the moisture in the ground flows into the cavity by the PC wall standing up in one sheet.
이를 개선하기 위해 최근에는 샌드위치 패널 형태로 된 복수의 피씨 벽체 사이에 현장 콘크리트를 타설하여 양생함으로써, 2~3중 벽체에 의한 방수 기능을 일부 확보하고 있는 실정이다.In order to improve this, in recent years, by casting concrete on-site between a plurality of PC walls in the form of sandwich panels, the situation is securing a part of the waterproof function by the double wall.
그러나, 이와 같은 종래의 복수 피씨 벽체는 서로 상호간 결속을 위해 타이볼트가 너트에 의해 서로 관통되면서 끝단이 조립되도록 형성되어 결국 외측 피씨 벽체에 구멍이 형성되는 바, 이는 벽체의 내외측을 관통하면서 결합된 타이볼트의 외측 앙카철이 부식되는 결과를 초래하게 되어 지중의 수분이 공동구 내로 침투되는 문제가 계속되고 있는 실정이다.
However, the conventional multiple PC walls are formed so that the ends are assembled while the tie bolts penetrate each other by nuts for mutual binding, and thus a hole is formed in the external PC walls, which are coupled while penetrating the inside and the outside of the wall. As a result of the corrosion of the outer anchor iron of the tie bolts, there is a problem that water in the ground penetrates into the cavity.
본 발명은 상술한 문제점을 해결하기 위한 것으로, 그 기술적 요지는 용수나 배수용의 수로가 도로, 철도, 제방 등의 아래에 매설되거나 전선로, 통신선로, 수도관, 열수송관, 중수도관, 쓰레기 수송관, 가스관, 하수도관 등 여러 가지 시설물을 도로 지하에 공동으로 매설하기 위하여 설치하는 공동구에 있어서, 상기 공동구를 구성하는 합벽 구조물에 관한 것으로, 합벽 구조물로 이루어진 공동구는 매립된 지반 외부로부터 구조물의 내부로 물이 침투되지 않도록 형성되는 바, 이러한 합벽 구조물은 프리캐스트 콘크리트 부재인 외측판과 내측판(피씨패널)이 기초콘크리트의 면상에서 일정한 공간부를 형성하며 기립되도록 하되, 외측판의 면상에는 기존의 내측판과의 조립을 위한 타공 구간 및 몰탈 채움 마감처리부가 형성되지 않도록 함으로써, 앙카철이 부식되는 것을 원천적으로 방지함은 물론 공동구 내부로의 오폐수 등이 유입되는 것을 근본적으로 차단하여 구조 안전성이 확보되도록 하는 것을 특징으로 하는 프리캐스트 콘크리트 부재와 현장타설 콘크리트가 결합된 공동구용 합벽 구조물을 제공함에 그 목적이 있다.The present invention is to solve the above problems, the technical gist of the water or drainage channel is buried beneath the road, railroad, embankment, or the like, the electric line, communication line, water pipe, heat transport pipe, heavy water pipe, garbage transport In the joint constituting various facilities such as pipes, gas pipes, sewer pipes to be buried underground in the road, relates to the plywood structure constituting the cavities, the cavities made of the plywood structure from the outside of the buried ground The plywood structure is formed so that water does not penetrate, so that the outer plate and the inner plate (PC panel), which are precast concrete members, stand up to form a predetermined space portion on the surface of the foundation concrete, but existing on the surface of the outer plate. Anchor by preventing formation of perforation section and mortar filling finish for assembly with inner plate The precast concrete member and the cast-in-place concrete combined with the precast concrete member, characterized in that it prevents the corrosion of the source at the source as well as fundamentally block the inflow of wastewater into the interior of the hollow ball to ensure structural safety The purpose is to provide.
