먼저, 표면처리단계(S1)는 시공대상 콘크리트구조물(10)의 현장 여건을 정확하게 확인하여 조사하고, 시공 대상 콘크리트구조물(10)에 사용할 철판(30)의 수량 및 충전할 충전재(50)의 양을 결정한 후, 시공 대상 콘크리트구조물(10)의 표면의 열화부위와 박리부위 및 들뜬부위를 제거하고, 제거된 콘크리트(12) 열화부위의 단면을 보수하여 복구함과 동시에 콘크리트(12) 표면에서 발생되는 레이턴스를 제거하며, 보수된 콘크리트(12) 부위를 와이어 브러시 및 고압수 세정기를 이용하여 깨끗하게 청소하는 단계이다.First, the surface treatment step (S1) is to accurately check and investigate the site conditions of the concrete structure 10 to be constructed, the quantity of the iron plate 30 to be used for the concrete structure 10 to be constructed and the amount of filler 50 to be filled After deciding on the surface of the concrete structure 10, the deterioration site, the exfoliation site, and the excitation site are removed, and the cross section of the removed concrete site 12 is repaired and repaired and generated on the surface of the concrete 12. Removing the latencies, and cleans the repaired concrete 12 portion using a wire brush and a high pressure water cleaner.
이어서, 철판설치단계(S2)는 콘크리트구조물(10)의 콘크리트(12) 표면에 앵커(20) 삽입용 구멍을 적절한 개수로 천공하여 천공부(14)를 형성하고, 이 천공부(14) 주위의 콘크리트(12) 표면을 콘크리트(12) 천공에 따른 먼지나 이물질 등을 에어건을 사용하여 완전히 제거하며, 콘크리트(12)의 천공부(14)에 적절한 개수의 앵커(20)를 삽입 고정한다.Subsequently, the iron plate installation step (S2) forms a perforated portion 14 by drilling an appropriate number of holes for inserting the anchor 20 in the surface of the concrete 12 of the concrete structure 10, and surrounds the perforated portion 14. The surface of the concrete 12 is completely removed by using an air gun to remove dust or foreign substances, etc. due to the drilling of the concrete 12, inserting and fixing the appropriate number of anchors 20 in the perforated portion 14 of the concrete 12.

And the tight contact portion of the iron plate 30 to be completely sealed.
이어서, 충전단계(S4)는 철판(30)과 콘크리트(12) 표면과의 사이에 설치된 주입구(34)에 합성고분자 무기질계 세라믹 충전재(50)를 주입함과 동시에 확인구(36)로 충전재(50)가 유출되는지 여부를 확인하면서 충전재(50)를 주입토록 한다.Subsequently, in the filling step S4, the synthetic polymer inorganic ceramic filler 50 is injected into the injection hole 34 installed between the iron plate 30 and the surface of the concrete 12, and at the same time, the filler ( Filling the filling material 50 while checking whether or not 50 is leaked.
이 때, 사용되는 충전재(50)는 무기질 세라믹1, 합성고분자0.2, 물0.2의 배합비율로 혼합한 합성고분자 무기질계 세라믹 충전재(50)를 사용하는 주입하는 바, 충전재(50)의 주입시 발생되는 충전재(50) 사이의 공극을 방지하기 위해 철판(30)의 하부에서부터 충전재(50)를 주입하며, 저압으로 충전재(50)를 주입 시공하고, 넓은 부분의 충전재(50) 주입시에는 철판(30)의 중앙 하부부터 주입함과 동시에 충전되는 철판(30)부위를 해머 등으로 타격하여 충전상태를 확인하면서 주입하도록 한다.In this case, the filler 50 to be used is injected using the synthetic polymer inorganic ceramic filler 50 mixed with the inorganic ceramic 1, the synthetic polymer 0.2, the water 0.2 of the mixing ratio, it occurs when the filler 50 is injected In order to prevent voids between the fillers 50 to be injected from the bottom of the iron plate 30, the filler 50 is injected, the filling material 50 is injected at a low pressure, and when the filler 50 is injected in a wide portion of the iron plate ( While injecting from the bottom of the center of 30) at the same time to hit the portion of the iron plate 30 is filled with a hammer or the like to check the state of filling.
마지막으로 마감단계(S5)는 상기한 충전단계(S4)에서 철판(30)의 주입구(34)를 통해 충전재(50)를 완전히 주입한 후, 이를 소정의 온도 및 기간으로 경화시켜 양생한 후, 주입구(34) 및 확인구(36)를 철판(30)에서 제거하는 한편, 상기 철판(30)의 표면을 부식을 방지하기 위해 방청도료를 1 내지 2회 도포하여 방청 처리하고, 상기 방청도포면상에 원하는 색상의 도료를 도포하여 철판(30)의 표면을 마감 처리한다.Finally, after finishing the filling step (S5) through the inlet (34) of the iron plate 30 in the filling step (S4) completely injected, and cured it to a predetermined temperature and period, While removing the injection hole 34 and the confirmation port 36 from the iron plate 30, in order to prevent corrosion of the surface of the iron plate 30 by applying an antirust coating 1 to 2 times, the antirust treatment on the surface The paint of the desired color is applied to finish the surface of the iron plate (30).
상기한 바와 같은 단계를 통해 시공되는 콘크리트구조물(10)은 그 콘크리트구조물(10)의 표면을 철판(30)으로 보강할 때 본 발명을 사용함으로써, 높은 접착력으로 장기적인 내구성이 증대되며, 콘크리트(12)와 철판(30) 사이의 접합면이 중성화되는 것을 방지함으로써 콘크리트(12) 표면으로부터 철판(30)이 탈락되는 것이 방지되며, 철판(30)과 충전재(50)의 열팽창계수가 유사하므로 철판(30)과 충전재(50) 사이에 영구적인 접착력을 유지시킬 수 있는 작용효과가 있다. The concrete structure 10 is constructed through the steps as described above, by using the present invention when reinforcing the surface of the concrete structure 10 with the iron plate 30, the long-term durability is increased with high adhesive strength, concrete (12 ) To prevent the iron plate 30 from falling off from the surface of the concrete 12 by preventing the bonding surface between the steel plate 30 and the steel plate 30, and the thermal expansion coefficient of the iron plate 30 and the filler 50 is similar to the iron plate ( 30) and the filler 50 has the effect of maintaining a permanent adhesive force.
이상에서 설명한 바와 같이, 본 발명에 따른 콘크리트구조물의 표면에 합성고분자 무기질계 세라믹 충전재를 충전하여 철판을 부착시키는 철판부착 콘크리트구조물 및 이의 시공방법은 콘크리트구조물과 물성치가 유사하고 콘크리트와 철판에 접착력이 강하며 열팽창계수가 유사한 합성고분자 무기질계 세라믹 충전재를 사용하여 철판을 부착함으로써, 천장슬래브나 보부위 및 기둥부위에 일체화 시공이 가능한 이점이 있다.As described above, the steel plate-attached concrete structure and its construction method for filling the surface of the concrete structure according to the present invention with a synthetic high molecular inorganic ceramic filler to attach the iron plate and the construction method is similar to the concrete structure and the adhesive strength to the concrete and iron plate By attaching the steel plate using a synthetic polymer inorganic filler having a strong and similar thermal expansion coefficient, there is an advantage that can be integrated into the ceiling slab, beam portion and column portion.
