Description

콘크리트 구조물 단면복구공법{REPAIRING METHOD FOR CROSS-SECTION RESTORATION OF CONCRETE STRUCTURES}REPAIRING METHOD FOR CROSS-SECTION RESTORATION OF CONCRETE STRUCTURES}

본 발명은 기존 콘크리트 구조물과의 접착력은 물론, 항균성이 우수한 보강접착제와 단면복구제를 활용한 콘크리트 구조물의 단면을 복구하는 공법에 관한 것이다.The present invention relates to a method for restoring a cross section of a concrete structure using an adhesive force with an existing concrete structure, as well as a reinforcing adhesive having excellent antibacterial properties and a cross-sectional recovery agent.

일반적으로 다양한 용도로 사용되고 있는 철근으로 보강하고 있는 콘크리트 또는 철근콘크리트 구조물의 경우, 환경조건에 따라 콘크리트가 분리되어 탈락하는 결함이 빈번히 발생되고 있다.In general, in the case of concrete or reinforced concrete structures that are reinforced with reinforcing bars used in various applications, defects in which concrete is separated and dropped according to environmental conditions are frequently generated.

콘크리트 또는 철근콘크리트 구조물은 사용 중에 각종 부식성 가스나 부식성 용액 및 물에 의한 화학적 침식, 중성(탄산)화, 염해 및 동해 등에 의한 팽창압력에 기인하거나, 또는 캐비테이션(Cavitation)에 의한 수압에 기인하여, 또는 차량에 의한 마모 등에 기인하여 표면(피복)콘크리트가 탈락하여 생기는 단면결손 결함이 반드시 발생되며, 이러한 결함은 구조내력의 저하와 밀접하게 관계하고 결합부위의 확대로 인하여 대형사고로 이어질 우려가 크므로 대부분 신속히 단면복구를 하여야 한다.Concrete or reinforced concrete structures may be caused by chemical erosion by various corrosive gases or corrosive solutions and water during use, due to expansion pressure due to neutralization (carbonate), salt and east sea, or due to hydraulic pressure by cavitation, Alternatively, cross-sectional defects caused by the dropping of the surface (coated) concrete due to abrasion caused by the vehicle must occur, and these defects are closely related to the decrease in structural strength and are likely to lead to large-scale accidents due to the expansion of the coupling site. In most cases, the section recovery should be done quickly.

이러한 단면복구 공법에는 다양한 공법이 있으나, 다공질재료인 콘크리트의 특성 즉, 콘크리트 내부에는 물(주로 시멘트 성분이 용해된 pH 120 이상의 강알칼리)이 가득 찬 무수히 많은 세공이 있으며, 이러한 세공내의 물은 외기의 온도변화에 따라 연속된 세공(극히 미세한 균열)을 경유하여 표면(접착계면)으로 이동(6)하여 상부에 도포한 접착제와의 계면을 적셔 접착 내구성을 저하시키게 되므로, 종래의 접착계면을 요철처리하거나 강화시키는 방법으로는 단면복구 보수한 부분과의 충분한 접착력과 접착 내구성을 확보할 수 없는 문제가 있다.Although there are various methods for such a cross-sectional recovery method, there are countless pores filled with water (mainly strong alkali of pH 120 or more in which cement component is dissolved) of concrete, that is, porous material. As the temperature changes, it moves to the surface (adhesion interface) through the continuous pores (extremely fine cracks) and soaks the interface with the adhesive applied on the upper side, thereby lowering the adhesion durability. In this case, there is a problem in that sufficient adhesive strength and endurance of the end face recovery and repairing portion cannot be secured.

따라서, 콘크리트 또는 철근콘크리트 구조물과 단면복구제의 계면접착력 및 접착내구성을 향상시킬 수 있는 새로운 단면복구공법에 대한 개발이 요구된다.Therefore, the development of a new cross-sectional recovery method that can improve the interfacial adhesion between the concrete or reinforced concrete structure and the cross-sectional recovery agent and the adhesion durability.

본 발명에서 치핑에 의해 갈아내는 콘크리트 외면의 깊이는 해당 콘크리트 구조물의 두께와 대비하여 최소 35mm 내지 50mm 이내의 깊이를 갖도록 치핑하여 후술하는 보강접착제(200)와 단면복구제(300)가 형성된 이후에 해당 콘크리트 구조물(C)의 두께와 동일하게 적용될 수 있도록 한다.The depth of the concrete outer surface ground by chipping in the present invention is chipping to have a depth of at least 35mm to 50mm in contrast to the thickness of the concrete structure after the reinforcing adhesive 200 and the cross-sectional recovery agent 300 to be described later formed To be applied equal to the thickness of the concrete structure (C).

그리고, 상기 2)단계(S200)인 보강구조물 설치단계는 도 2 및 도 3에 도시한 바와 같이, 후술하는 보강접착제(200)가 콘크리트 구조물 외면에 형성되기 이전에 상기 보강접착제(200)가 상기 보강구조물(100)을 뼈대로 하여 해당 콘크리트 구조물(C)에 고정되어 자리잡을 수 있도록 하기 위한 것이며, 나아가서는 상술한 1)단계(S100)에서 콘크리트 구조물 외면에 치핑을 실시시에 그 진동에 의하여 또 다른 크랙(crack)이 발생시에 해당 크랙이 더 이상 진행되지 않도록 보강하는 기능도 포함하기 위한 단계이다.In addition, the step 2) (S200) of the reinforcing structure installation step, as shown in Figures 2 and 3, before the reinforcing adhesive 200 to be described later formed on the outer surface of the concrete structure is the reinforcing adhesive 200 is The reinforcing structure 100 as a skeleton to be fixed to the concrete structure (C) to be located, and furthermore by the vibration when the chipping on the outer surface of the concrete structure in step 1) (S100) described above When another crack occurs, the step is to include a function of reinforcing the crack so that no further progress.

예컨대 본 발명에서의 보강구조물(100)은 바둑판 배열의 격자 형상을 갖는 격자체(110)와 고정핀(120)을 포함한다.For example, the reinforcement structure 100 according to the present invention includes a grid 110 having a grid shape of a checkerboard arrangement and a fixing pin 120.

격자(mesh)형상을 갖는 격자체(110)는 부식성에 강하고 열팽창계수가 낮되 후술하는 보강접착제(200)가 콘크리트 구조물(C)에 형성되어 경화한 이후에 상기 보강접착제(200)가 해당 콘크리트 구조물(C)에 고정될 수 있게 뼈대를 이룰 수 있는 금속의 재질을 사용한다.The grid 110 having a mesh shape is strong in corrosiveness and has a low coefficient of thermal expansion, but after the reinforcing adhesive 200 described below is formed on the concrete structure C and cured, the reinforcing adhesive 200 is applied to the concrete structure. Use a metal material that can form a skeleton to be secured to (C).

격자체(110)에 형성된 천공부(111)는 필요에 따라 원형이나 다각으로 천공형성될 수 있으며, 그 천공된 지름은 복구하고자 하는 콘크리트 구조물의 상태에 따라 달라질 수 있다.The perforations 111 formed in the grid 110 may be perforated in a circular or polygonal shape as needed, and the perforated diameter may vary depending on the state of the concrete structure to be restored.

즉, 복구하고자 하는 콘크리트 구조물이 손상 정도가 높으면 해당 콘크리트 구조물에 고정핀(120)의 사용은 최소화하여 격자체(110)에 의해 보강접착제(200)가 해당 콘크리트 구조물(C)에 접착된 이후에 견고함을 유지할 수 있게 상기 격자체(110)에 형성된 천공부(111)를 촘촘히 형성하여 그 견고함을 유지한다.That is, if the concrete structure to be repaired has a high degree of damage, the use of the fixing pin 120 is minimized to the concrete structure, after the reinforcing adhesive 200 is adhered to the concrete structure C by the grid body 110. The perforations 111 formed in the lattice body 110 are closely formed to maintain the firmness, thereby maintaining the firmness.

반면, 복구하고자 하는 콘크리트 구조물(C)의 손상 정도가 낮으면 해당 콘크리트 구조물(C)에 복수의 고정핀(120) 사용이 용이하다고 판단하여 격자체(110)에 형성된 천공부(111)의 간격을 상술한 경우보다 넓게 하여 콘크리트 구조물과 보강접착제(200) 간의 친화력은 물론, 견고함도 함께 유지될 수 있도록 하는 것이다.On the other hand, if the damage degree of the concrete structure (C) to be repaired is low, it is determined that the use of a plurality of fixing pins 120 in the concrete structure (C) is easy to determine the interval between the perforations 111 formed in the grid 110 By making it wider than the case described above to ensure that the affinity between the concrete structure and the reinforcing adhesive 200, as well as robustness can be maintained together.

아울러 수직 및 수평방향으로 서로 이어지는 격자체(110) 외면에는 그 길이방향으로 다수의 관통공(113)이 천공형성되어 고정핀(120)이 관통 삽입될 수 있는 구조를 갖도록 한다.In addition, the outer surface of the grid 110 connected to each other in the vertical and horizontal directions is formed with a plurality of through holes 113 in the longitudinal direction so that the fixing pin 120 can be inserted through.

고정핀(120)은 기둥형상을 갖도록 형성되어 상술한 격자체(110)에 형성된 관통공(113)에 관통 삽입되며, 그 일단은 뾰족한 형상으로 이루어져 상기 관통공(113)에 삽입된 상태로 치핑이 이루어진 콘크리트 구조물(C)에 박혀 고정될 수 있도록 한다.Fixing pin 120 is formed to have a columnar shape is inserted through the through-hole 113 formed in the above-described grating body 110, one end of the pointed shape is chipped in the state inserted into the through-hole 113 This is made to be embedded in the concrete structure (C) to be fixed.

고정핀(120)은 필요에 따라 격자체(110)에 형성된 관통공(113) 전부에 삽입되어 콘크리트 구조물(C)에 고정될 수 있으나, 필요에 따라 다수의 상기 관통공(113) 중 일부에만 관통 삽입되어 해당 콘크리트 구조물(C)에 박혀 상기 격자체(110)가 콘크리트 구조물(C)에 고정될 수 있도록 한다.The fixing pin 120 may be inserted into all of the through holes 113 formed in the lattice 110 as needed, and may be fixed to the concrete structure C, but only a part of the plurality of through holes 113 as necessary. It is inserted through and embedded in the concrete structure (C) so that the grid 110 can be fixed to the concrete structure (C).

이때, 상술한 보강구조물(100)은 치핑이 이루어진 콘크리트 구조물(C)의 단면을 기준으로 외측 방향으로 25mm 내지 33mm 이상 돌출되지 않는 길이를 갖도록 설치되어 후술하는 보강접착제(200)는 물론, 단면복구제(300)가 콘크리트 구조물(C) 외면에 형성시에 상기 보강구조물(100)이 외부로 노출되지 않도록 하여 상기 보강구조물(100)의 틈새 등을 통해 습기나 이물질 등이 유입되지 안도록 하는 것이 바람직하다.At this time, the above-mentioned reinforcing structure 100 is installed to have a length that does not protrude more than 25mm to 33mm in the outward direction based on the cross section of the concrete structure C chipping is made, as well as reinforcement adhesive 200 to be described later, cross-sectional recovery When the 300 is formed on the outer surface of the concrete structure (C) to prevent the reinforcement structure 100 is exposed to the outside so that moisture or foreign matters, etc. through the gap of the reinforcement structure 100 is not introduced. desirable.

그리고, 상기 3)단계(S300)인 보강접착제(200) 형성단계는 도 4에 도시한 바와 같이, 상술한 보강구조물(100)이 설치된 콘크리트 구조물(C) 외면에 소정 두께를 갖도록 형성 후 경화되어 상기 보강구조물(100)의 고정은 물론, 치핑에 의한 새로운 크랙을 메우고, 후술하는 단면복구제(300)가 견고하게 해당 콘크리트 구조물(C)에 부착될 수 있도록 하기 위한 구성이다.Then, the forming step of the reinforcing adhesive 200 in step 3) (S300) is hardened after forming to have a predetermined thickness on the outer surface of the concrete structure (C), the reinforcing structure 100 is installed as shown in FIG. Fixing the reinforcing structure 100, as well as filling a new crack by chipping, and is configured to allow the cross-sectional recovery agent 300 to be described later to be firmly attached to the concrete structure (C).

예컨대 본 발명에서의 보강접착제(200)는 EVA(ethylene-vinyl acetate copolymer), LDPE(Low Density Polyethylene), 발포재, 발포보조재, 항균첨가제 및 오일의 혼합물로 형성되며, 보강구조물(100)이 설치된 콘크리트 구조물(C) 외면에 25mm 내지 33mm의 두께를 갖도록 형성된다.For example, the reinforcing adhesive 200 in the present invention is formed of a mixture of EVA (ethylene-vinyl acetate copolymer), LDPE (Low Density Polyethylene), foaming material, foaming aid, antibacterial additives and oil, the reinforcing structure 100 is installed The outer surface of the concrete structure (C) is formed to have a thickness of 25mm to 33mm.

여기서 보강접착제(200)의 바람직한 혼합은 EVA(ethylene-vinyl acetate copolymer) 100 중량부에 대하여, LDPE(Low Density Polyethylene) 24.2 내지 25.7 중량부, 발포재 31.77 내지 35.4 중량부, 발포보조재 20.1 내지 26.4 중량부, 항균첨가제 15.7 내지 19.7 중량부 및 오일 3 내지 5.3 중량부의 혼합물로 이루어지도록 함으로써, 고농도의 보강접착제(200)를 통해 콘크리트 구조물(C)과의 접착력은 물론, 후술하는 단면복구제(300)와의 접착력도 극대화될 수 있도록 한다.Here, the preferred mixing of the reinforcing adhesive 200 is based on 100 parts by weight of EVA (ethylene-vinyl acetate copolymer), 24.2 to 25.7 parts by weight of low density polyethylene (LDPE), 31.77 to 35.4 parts by weight of foam material, 20.1 to 26.4 parts by weight of foam aid Part, the antimicrobial additive 15.7 to 19.7 parts by weight and the oil 3 to 5.3 parts by weight of the mixture, through the high concentration of reinforcing adhesive 200, as well as the adhesive strength with the concrete structure (C), the cross-sectional recovery agent 300 to be described later Also, the adhesion between the two can be maximized.

아울러 보강접착제(200)는 고정의 편의상 발포노즐을 통해 콘크리트 구조물(C) 외면에 발포되어 크랙에 상기 보강접착제(200)가 용이하게 유입될 수 있도록 하며, 발포된 이후에 작업자에 의해 평탄작업을 추가로 실시할 수 있다.In addition, the reinforcement adhesive 200 is foamed on the outer surface of the concrete structure (C) through the foam nozzle for convenience of fixing, so that the reinforcement adhesive 200 is easily introduced into the crack, and after the foaming, the flat work by the operator It can be carried out additionally.

나아가 보강접착제(200)가 형성된 콘크리트 구조물(C)은 약 30분 내지 1시간 동안의 건조공정을 추가로 실시하여 상기 보강접착제(200)의 물성이 콘크리트 구조물(C)에 유연(말랑한 상태)한 상태로 형성될 수 있도록 하며, 건조공정 이후에 상기 보강접착제(200)의 표면온도가 50 내지 60℃ 이내일 때, 후술하는 단면복구제(300)를 그 외면에 형성할 수 있도록 한다.Furthermore, the concrete structure (C) on which the reinforcing adhesive 200 is formed is further subjected to a drying process for about 30 minutes to 1 hour so that the physical properties of the reinforcing adhesive 200 are flexible (soft) to the concrete structure (C). It can be formed in a state, and when the surface temperature of the reinforcing adhesive 200 after the drying process within 50 to 60 ℃, it is possible to form a cross-sectional recovery agent 300 to be described later on the outer surface.

여기서 보강접착제(200)의 표면온도가 50 내지 60℃ 이내일 때, 단면복구제(300)를 상기 보강접착제(200) 외면에 형성하는 이유는 해당 온도 이상인 상태에서 상기 단면복구제(300)가 도포되면 상기 단면복구제(300)가 상기 보강접착제(200) 내부로 많은 양이 흡수되어 상기 단면복구제(300)의 층 형성에 방해가 되며, 해당 온도 이하인 경우에는 상기 보강접착제(200)와 상기 단면복구제(300)와의 접착력이 저하되어 장시간 이후에 상기 단면복구제(300) 형성 층이 떨어져 나갈 수 있기 때문이다.In this case, when the surface temperature of the reinforcing adhesive 200 is within 50 to 60 ° C., the reason for forming the cross-sectional recovery agent 300 on the outer surface of the reinforcing adhesive 200 is that the cross-sectional recovery agent 300 is in a state above the corresponding temperature. When applied, the single-sided recovery agent 300 absorbs a large amount into the reinforcing adhesive 200, thereby hindering the layer formation of the single-sided recovery agent 300, and when the temperature is lower than the corresponding temperature, the reinforcing adhesive 200 and This is because the adhesive force with the cross-sectional recovery agent 300 is lowered so that the cross-sectional recovery agent 300 forming layer may fall off after a long time.

그리고, 4)단계(S400)인 단면복구제 형성단계는 도 5에 도시한 바와 같이, 소정의 표면온도를 갖는 보강접착제(200)가 형성된 콘크리트 구조물(C)에 소정의 두께를 갖도록 형성되어 복구가 이루어진 해당 콘크리트 구조물을 성형하기 위한 단계이다.4, the step (S400) to form a cross-sectional recovery agent is recovered to have a predetermined thickness in the concrete structure (C) formed with a reinforcing adhesive 200 having a predetermined surface temperature, as shown in FIG. Steps for molding the concrete structure made up.

예컨대 본 발명에서의 단면복구제(300)는 시멘트, 첨가제, 규사, 토르마린, 무기질 혼합재, 황토 및 강도증진제의 혼합물로 이루어져 보강접착제(200)가 형성된 표면에 스프레이 방식으로 도포되어 형성된다.For example, the cross-sectional recovery agent 300 in the present invention is made of a mixture of cement, additives, silica sand, tourmaline, inorganic mixtures, ocher and strength enhancers are formed by applying a spray method to the surface on which the reinforcing adhesive 200 is formed.

여기서 단면복구제(300)를 형성하는 혼합물은 시멘트 100 중량부에 대하여, 첨가제 10 내지 15.7 중량부, 규사 20 내지 23 중량부, 토르마린 8.7 내지 9.4 중량부, 무기질 혼합재 13.7 내지 15.3 중량부, 황토 3.8 내지 4.3 중량부 및 강도증진제 6 내지 8 중량부로 혼합된다.Here, the mixture forming the cross-sectional recovery agent 300 is based on 100 parts by weight of cement, 10 to 15.7 parts by weight of additives, 20 to 23 parts by weight of silica sand, 8.7 to 9.4 parts by weight of tourmaline, 13.7 to 15.3 parts by weight of inorganic mixture, 3.8 parts of clay To 4.3 parts by weight and strength enhancers 6 to 8 parts by weight.

이러한 중량으로 첨가되되 보강접착제(200)와의 접착력 증진에 사용되는 상기 첨가제는 포졸란, 플라이애쉬(fly ash) 및 고로슬래그(blast furnace slag) 중 어느 하나를 사용한다.The additive, which is added at such a weight, and used to enhance adhesion with the reinforcing adhesive 200, uses any one of pozzolan, fly ash, and blast furnace slag.

나아가 토르마린은 일명 전기석으로 불리는 광물로 마찰이나 외부에서 가해지는 열(예를 들어, 태양광)에 의해 결정의 양끝이 플러스극(+극)과 마이너스극(-극)으로 대전(帶電)하는 성질의 광물로 약 0.03 내지 0.06A(암페어)의 미약전류를 발생시켜 그 표면에 습기로 인한 곰팡이 등이 생성되는 것을 차단하는 항균의 기능을 갖도록 한다.Furthermore, tourmaline is a mineral called a tourmaline, and both ends of the crystal are charged with positive and negative poles by friction or heat applied externally (for example, sunlight). It generates a weak current of about 0.03 to 0.06A (amps) as a mineral to have an antimicrobial function of blocking the formation of mold and the like due to moisture on its surface.

이때, 토르마린은 900 내지 1,300 메쉬의 입자의 분말 형태로 혼합되어 지는 것이 바람직하다.At this time, the tourmaline is preferably mixed in the form of powder of 900 to 1,300 mesh particles.

이를 통해 후술하는 마감단계에서의 페인트 등이 콘크리트 구조물(C)에 도포된 이후에 장시간후 해당 페인트층(P-a)이 벗겨져도 토르마린이 포함된 단면복구제(300)를 통해 항균의 효능을 갖도록 하는 것이다.(도 6 참조)Through this, after the paint and the like in the finishing step to be described later is applied to the concrete structure (C) for a long time, even if the paint layer (Pa) is peeled off to have the antibacterial effect through the cross-sectional recovery agent 300 containing tourmaline (See Figure 6).

한편, 본 발명에서의 단면복구제(300)는 상술한 보강구조물(100)은 물론, 상기 보강접착제(200)가 외부로 노출되지 않게 상기 보강접착제(200) 표면을 기준으로 10mm 내지 16mm의 두께를 갖도록 형성된다.On the other hand, the cross-sectional recovery agent 300 in the present invention, as well as the reinforcing structure 100 described above, the thickness of 10mm to 16mm based on the surface of the reinforcing adhesive 200 so that the reinforcing adhesive 200 is not exposed to the outside. It is formed to have.

그리고, 5)단계(S500)인 마감단계는 상술한 단면복구제(300)가 형성된 표면에 평탄 작업을 실시하거나 평탄 작업 이후에 페인트 층(P-a)등을 도포하여 복구가 완성된 콘크리트 구조물(C)을 형성하기 위한 단계로 이는 통상적으로 실시되는 과정이라 본 발명의 요지를 흐리지 않도록 상세한 설명은 생략하도록 한다.And, 5) the finishing step (S500) is a concrete structure (C) repairing is completed by applying a paint layer (Pa) or the like after the flat work on the surface of the above-described cross-sectional recovery agent 300 is formed or flat work This is a step for forming a) is a commonly performed process so that the detailed description will be omitted so as not to obscure the subject matter of the present invention.

전술한 바와 같은 단계들로 이루어진 본 발명에 따른 복구공법(1)은 종래와는 차별적으로 치핑이 이루어진 콘크리트 구조물(C) 외면에 보강구조물(100)을 설치하여 상기 보강구조물(100)에 도포되는 보강접착제(200)가 해당 콘크리트 구조물(C)과 견고하게 접착될 수 있도록 하며, 상기 보강접착제(200) 외면에 도포되는 단면복구제(300)는 항균성을 갖는 광물을 포함하고 있어 장시간 외부에 노출되어도 습기에 의한 곰팡이 등이 생성되지 못하도록 하는 효과를 갖게 된다.Recovery method (1) according to the present invention made of the steps as described above is applied to the reinforcement structure 100 by installing the reinforcement structure 100 on the outer surface of the concrete structure (C) made chipping differently from the conventional The reinforcement adhesive 200 is to be firmly bonded to the concrete structure (C), and the cross-sectional recovery agent 300 applied to the outer surface of the reinforcement adhesive 200 contains a mineral having antimicrobial exposure to the outside for a long time Even if it is, it has the effect of preventing the formation of mold and the like due to moisture.
