Since the construction of the circular structure of the wastewater treatment plant is difficult, the construction method of the circular structure will be described.

상기 만곡된 판넬(10) 다수로 지면에 콘크리트로 양생시킨 기초슬래브(30) 위에 거푸집(40)을 설치하는데, 그 설치과정은 기초슬래프(30)의 모양이 구조물의 형에 따라 정해지며 여기에서는 원형구조물이므로, 기초슬래브(30)를 원판형으로 양생시키며, 상기 기초슬래브(30)가 양생되기 전에 제1도에 표현된 평판상의 판넬(10)을 원판형으로 절단하고 철띠(20)에 꽂임철봉(21) 다수를 직각 방향으로 결속시켜 판넬(10)의 평활면(13)이 상면으로 되게하여 양생되지 않은 기초슬래브(30)위에 얹은 다음 압력을 가하여 상기 판넬요철부 철근과 꽂임철봉(21)들이 기초슬래브(30) 속으로 파고들어 양생된 후에는 기초슬래브(30) 위의 판넬(10)이 고정설치되어 구조물의 바닥(50)을 이루게 되는 것이다.The formwork 40 is installed on the foundation slab 30 cured with concrete to the ground with a plurality of curved panels 10, the installation process of which the shape of the foundation slab 30 is determined according to the type of the structure here Since it is a circular structure, the foundation slab 30 is cured in a disc shape, and before the foundation slab 30 is cured, the plate-shaped panel 10 represented in FIG. A plurality of mounting bars 21 are bound in a right angle so that the smooth surface 13 of the panel 10 becomes an upper surface, placed on an uncured foundation slab 30, and then the pressure is applied to the panel reinforcing bars and the mounting bars ( After the 21 is dug into the foundation slab and cured, the panel 10 on the foundation slab 30 is fixed to form the bottom 50 of the structure.

이후, 상기한 거푸집(40)을 바닥(50)을 이루는 원판형 판넬(10) 둘레에 만곡형 판넬(10) 수개를 원통형으로 세운 다음 그 외곽에 다수의 주철근(22)를 기초 슬래브(30)를 기반으로 기립시킨후, 상기 주철근(22)을 이용하여 배력철근(23)을 2줄로 가설하고, 이 배력철근(23)간에 결속철근(24) 다수를 연결하며, 또, 외향의 배력철근(23) 상기 판넬(10)의 철띠(20)간에 일정간격으로 다수의 연결철근(25)을 결속시키며, 이후 외향측 배력철근(23)과 외부로 만곡형 판넬(10)을 세우는데 상기 외측판넬(10)은 그 평활면(13)이 내측으로 향하고 요철면(12)은 외측으로 향하도록 하여 외측 판넬(10)과 내측 판넬(10) 사이에 합성수지로된 다수개의 관(26)을 일정간격으로 대접시켜 내외측 판넬(10)의 철띠(20)에 천공된 폼타이핀공(20b)과 상기 관(26)을 통하여 폼타이핀(27)을 끼운다음 너트를 채워 콘크리트 타설시 내외측 판넬(10)의 벌어짐을 방지하여 벽체 거푸집(40)을 설치하게 되는 것이며, 또, 상기 거푸집(40)을 형성함에 있어서, 내측 판넬(10) 상단에는 합판을 재단하여서 되는 합판거푸집을 못으로 고정시켜 변형을 방지하고, 외측판넬(10)은 상,하단에 합판거푸집을 못으로 고정시켜 변형됨을 방지하도록 한다.Subsequently, a plurality of curved panels 10 are formed in a cylindrical shape around the disk-shaped panel 10 constituting the bottom 50, and then a plurality of cast irons 22 are formed on the outer side of the foundation slab 30. After standing on the basis of the above, the reinforcement reinforcement (23) using the main reinforcing bars (22) is hypothesized by two lines, connecting the plurality of binding reinforcement (24) between the reinforcing reinforcing bars (23), and outgoing reinforcement ( 23) The plurality of connecting reinforcing bars 25 are bound at regular intervals between the metal strips 20 of the panel 10, and then the outward side reinforcing bar 23 and the outside of the curved panel 10 to erect the outer panel 10, the smooth surface 13 faces inward and the uneven surface 12 faces outward so that a plurality of pipes 26 made of synthetic resin are spaced apart between the outer panel 10 and the inner panel 10 at regular intervals. The foam tie pins (27) through the form tie pin holes (20b) and the tube (26) perforated in the iron strip (20) of the inner and outer panels (10), and then insert the nuts. When filling the concrete to prevent the opening of the inner and outer panels 10 to install the wall formwork 40, and, in forming the formwork 40, the inner panel 10 by cutting the plywood to the top The plywood dies are fixed with nails to prevent deformation, and the outer panel 10 is fixed to the plywood dies with nails at the top and bottom to prevent deformation.

이상과 같이 기초슬래브(30) 위에 가설된 거푸집(40)에 콘크리트를 타설 양생후에는 폼타이핀(27)의 너트를 풀어 외측판넬(10)을 제거하면 제5도에서 보이는 원형구조물(60)이 형성되며, 상기 원형구조물(6)의 내면은 벽체의 내면측 판넬(10)은 요철부철띠(20)와, 배력철근(23), 주철근(22), 연결철근(25) 및 결속철근(24)에 의하여 콘크리트와의 이완성이 없이 결속일체가 되는 것이고, 상기 원형구조물(6)의 내면은 전체적으로 판넬(10)의 평활면(13)으로 되는 것이다.As described above, after pouring concrete into the formwork 40 laid on the foundation slab 30, by removing the outer panel 10 by releasing the nut of the form tie pin 27, the circular structure 60 shown in FIG. Is formed, the inner surface of the circular structure (6) is the inner surface side panel 10 of the wall is an uneven steel strip 20, the reinforcement bar 23, the main reinforcing bar 22, the connecting bar 25 and the binding bar ( 24) is to be a solid body without loosening with the concrete, the inner surface of the circular structure 6 is to be a smooth surface 13 of the panel 10 as a whole.

이후에는 바닥(50)의 판넬(10) 및 벽체의 판넬(10) 사이의 틈 또는 벽체를 형성하기 위한 벽체 판넬(10) 끼리의 사이틈은 용해시킨 폴리에티렌으로 용접하여 수밀성을 갖도록 하여 원형 콘크리트구조물을 시공하게 되는 것이다.Thereafter, the gap between the panel 10 of the floor 50 and the panel 10 of the wall or the gap between the wall panels 10 to form a wall is welded with dissolved polystyrene to have watertightness and a circular shape. It is to construct a concrete structure.

이상과 같이 본 발명은 판넬(10)을 이용한 거푸집(40)으로 축조하게 되어 종래 목재거푸집으로 시공하는 것보다는 거푸집 설치작업의 공정이 빠르고, 구조물의 내면이 폴리에티렌 재질의 판넬(10)로 수밀성을 갖도록 시공되는 것이어서, 오

폐수에 함유된 부식성화학성분을 상기 판넬(10)에 의하여 벽체 콘크리트와는 차단되어 결국 부식성화학 성분으로 인한 구조물의 벽체 부식 및 손상이 일어나지 않고 반영구적으로 사용하게 되는 수명을 갖게 되는 것이고, 폼타이핀(27)을 내외측 판넬(10)을 관통시키지 않고 내측판넬(10)의 철띠(27)와 외측판넬(10)의 철띠(27) 사이에 연결시켜 구조물의 형을 유지하도록 한 것이므로 내측판넬(10)에 폼타이핀(27) 연결용 구멍이 없이 구조물이 완성되는 것이므로 내측판넬(10)과 바닥판넬(10)의 틈만 폴리에티렌 가열 용접으로 밀폐시키도록 된 것이므로, 구조물 완성후 틈새 밀폐 작업도 매우 간편하게 된 작용, 효과를 나타내는 것이다.As described above, the present invention is constructed by the formwork 40 using the panel 10, so that the process of installing the formwork is faster than constructing the conventional wood formwork, and the inner surface of the structure is made of the panel 10 made of polystyrene. Is constructed to have watertightness, oh
Figure kpo00014
The corrosive chemical component contained in the waste water is blocked from the wall concrete by the panel 10, and thus has a lifespan that is used semi-permanently without causing corrosion and damage to the wall of the structure due to the corrosive chemical component. The inner panel (27) is connected between the metal strip 27 of the inner panel 10 and the metal strip 27 of the outer panel 10 without penetrating the inner and outer panels 10, so the inner panel ( 10) Since the structure is completed without the hole for connecting the form tie pin 27, only the gap between the inner panel 10 and the bottom panel 10 is to be sealed by polystyrene heating welding, so the gap sealing work after the completion of the structure It is also very easy to show the effect.
