Relates to a device.
지중에 굴착된 수직터널의 원지반을 보호하고 안정화시키기 위하여, 수직터널의 둘레면에 콘크리트를 소요 두께로 타설 경화시켜서 복공벽을 성형 시공하는 것이 통례이다.In order to protect and stabilize the original ground of vertical tunnels excavated in the ground, it is common practice to form a perforated wall by casting concrete to the required thickness on the peripheral surface of the vertical tunnel.
이전에는 수직터널의 복공벽을 성형 시공할 때에, 해당 작업위치에 거푸집을 조립 설치하고 미경화콘크리트를 타설한 후에, 거푸집을 해체시켜서 다음 작업위치에 재조립하여 설치하고 미경화콘크리트를 타설하는 반복적인 작업공정을 수행하여 왔다. 이때, 굴착된 수직터널 내부에는 거푸집을 존치시키거나 거푸집 설치작업을 안전하게 수행할 수 있는 공간이 확보되어 있지 못한 관계로, 거푸집을 조립하고 해체하는 작업을 수행하는 데 많은 어려움이 있었으며, 굴착된 수직터널 내에서 고소작업을 수행하는 작업자가 추락하여서 재해를 입는 안전사고가 빈번하게 발생되는 등의 심각한 문제점을 수반하게 되었다.Previously, when forming the perforated wall of the vertical tunnel, the formwork is assembled and installed in the corresponding work position, the unhardened concrete is poured, and then the formwork is disassembled and reassembled and installed in the next work position, and the unhardened concrete is poured repeatedly. Work process has been carried out. At this time, since there was not a space inside the excavated vertical tunnel to secure the formwork or to safely carry out the formwork installation, there were many difficulties in assembling and dismantling the formwork. It was accompanied by serious problems such as frequent accidents caused by accidents caused by workers falling down in tunnels.
이와 같은 문제점을 해소하고자 제안된 것으로 일본국 특허공보 소48-23386호(1973.07.13)에는 "가틀슬라이딩을 이용한 콘크리트 타설공법에 있어서, 그 겹치는 정도의 증감에 따라서, 자유롭게 신축가능하도록 교호로 중합시켜서 짜고, 그것을 연속시켜서 가틀을 형성하고 있는 점의 2종류의 패널의 겹치는 정도와, 패널을 서로 잡아서 인양하기 위하여 배치되는 요오크를 연결하여 지지하여 잡고있는 신축가능한 보의 신축을 콘크리트벽의 처리경사에 따라서 구한 직경의 차의 회전으로 가틀의 높이방향으로 동조시켜서, 일정비율로 신축시키는 구조를 가지는 것을 기술요지로 한 가틀슬라이딩장치"가 선출원공개되어 있다.Japanese Patent Publication No. 48-23386 (July 13, 1973) proposes to solve such a problem. "In the concrete pouring method using the slit sliding, according to the overlapping degree of increase and decrease, the polymerization is alternately made freely. Concrete wall treatment of stretchable beams held together by supporting the degree of overlap of two kinds of panels of points forming a frame by squeezing and weaving them, and connecting and supporting the yokes arranged to grab and lift the panels. [0009] A gait sliding device ", which is a technical subject of a structure having a structure in which it rotates in the height direction of a frame by the rotation of the difference of the diameter calculated | required according to the inclination, and expands and contracts by a fixed ratio, is proposed by the prior application.
또, 일본국 실용신안공보 소52-28327호(1977.06.28)에는 " 가동형틀과 고정형틀을 옆으로 연결하여 내경이 다른 2개의 링을 동심원상으로 배치하고, 양자의 링사이에 미경화콘크리트를 주입하여 콘크리트가 마르는 것을 기다려서 양자의 링을 동시에 상승시키는 작업을 반복하여서 굴뚝 또는 원통형구조물을 계속적으로 건조하는 장치에 있어서, 내외측의 양링의 고정형틀의 바닥판에 단면 ⊥형의 지렛대를 고정하여 그 형틀을 향하여 상방으로 돌출되는 부분에 각각 단면상의 보조편을 감착고정하여 내측링의 보조편의 좌우굴곡부 선단면에 채널형상(단면형의 형강)을 용착직립시키고 이것에 종횡으로 채널형강을 병착하여 잭함을 구성하여 고정형틀에 덮어씌워절치도록 하고 또 외측링의 보조편에 지렛대와 같이 횡채널형강에 상방으로 돌출시켜서 돌출부에 속하는 지렛대의 돌상부 및 보조편의 좌우굴곡부에 설치한 뚫린구멍에 환강을 완만하게 삽입시켜서 그 해당 환강을 횡채널강의 측판위에 돌출 설치한 돌출레일에 따라서 회전하여 움직이고 외측링의 고정형틀을 전후로 이동시키도록 한 구조를 가지는 형틀활동방식에 의한 원통형구축물의 건조장치"가 선출원 공개되어 있다.In addition, Japanese Utility Model Publication No. 52-28327 (August 28, 1977) said, "A movable mold and a fixed mold are connected sideways, and two rings with different inner diameters are arranged concentrically, and unhardened concrete is formed between the rings. In the apparatus for continuously drying the chimney or the cylindrical structure by repeating the operation of raising both rings at the same time by waiting for the concrete to dry by injecting them, the cross section of the inner ring is fixed to the bottom plate of the fixing frame of both inner and outer rings. Section on each part protruding upward toward the mold Fixing and fixing the upper part of the upper part, the channel shape (cross section) Welded and erected uprights) and channel channel steel in parallel to each other to form a jack box to cover the fixed mold and cut it out, and to protrude upwards in the horizontal channel steel like a lever on the side of the outer ring. Slowly insert the round holes into the drilled holes provided in the protrusions of the lever and the left and right bends of the auxiliary piece, and move the corresponding round holes along the protruding rails projected on the side plate of the transverse channel steel to move the fixed frame of the outer ring back and forth. Patent application of "drying device for a cylindrical structure by a frame activity method having a structure" is disclosed.
상기한 바와 같이 선출원공개된 가틀슬라이딩장치 또는 원통형구축물의 건조장치는 모두 슬립폼의 프레임 사이에 원주방향으로 일정간격마다 수직으로 세워진 슬라이딩 지주와, 슬립폼의 프레임 둘레에 설치된 수평아암에 결합되는 작동잭이 서로 협동하는 유형의 활동용 요오크로서 슬립폼을 상승 이동시켜 주도록 구성되어서, 슬립폼내에 미경화콘크리트를 계속적으로 타설하여서 원통형구축물을 건조할 수 있도록 하였다.As described above, the gantry sliding device or the drying device of the cylindrical structure disclosed in the first application are all coupled to a sliding support vertically erected at regular intervals in the circumferential direction between the frames of the slipform, and to the horizontal arm installed around the frame of the slipform. The jacks are configured to move the slipforms up and down as cooperative types of activity yokes, allowing the cylindrical structures to be built by continuously pouring uncured concrete into the slipforms.
그러나, 이와 같은 종래의 가틀슬라이딩장치나 원통형구축물의 건조장치에 있어, 활동용 요오크는 슬립폼 전체의 하중을 작용받는 잭로드들이 흔들리거나 휨변형됨을 방지하여 주기 위한 구조를 갖추고 있기 못하였기 때문에, 슬립폼이 이동하는 도중에 잭로드들이 심하게 흔들려서 완전히 경화되기 이전의 복공벽에 균열을 발생시키므로 시공품질이 저하될 뿐만 아니라, 슬립폼을 상승 이동시키는 데 지장을 초래하여서 복공벽의 성형작업을 능률적으로 수행할 수 없는 등의 문제점을 수반하게 되었다.However, in the conventional gantry sliding device or the drying device of the cylindrical structure, the active yoke did not have a structure to prevent the jack rods that are subjected to the entire load of the slip foam to shake or bend deformation. As the rod rods are shaken violently during the movement of the slipform, it causes cracks in the perforated wall before it is fully hardened. Therefore, the quality of construction is not only degraded, but it also affects the upward movement of the slipform. It came with problems such as not being able to perform.
본발명은 중량의 슬립폼 자중을 작용받는 잭로드들을 견실하게 지탱하여 주도록 구성하여서, 첫째 복공벽에 균열이 발생됨을 미연에 방지하여서 품질이 우수한 복공벽을 시공할 수 있도록 하여 주며, 둘째 복공벽 성형작업을 능률적으로 수행할수 있도록 하여서 시공성을 제고하여 주는 수직터널의 복공벽 성형용 슬립폼용 요오크장치를 제공하는 데 그 목적이 있다.The present invention is configured to support the heavy load of the slip-form weight of the jack rod, to prevent the occurrence of cracks in the first perforated wall in advance to enable the construction of a high quality perforated wall, the second perforated wall It is an object of the present invention to provide a yoke device for slip foam for forming a perforated wall of a vertical tunnel, which improves workability by making molding work efficient.
