본 발명은 콘크리트구조물 보강용 섬유-강판 복합패널과 이의 제조방법 및 이를 이용한 콘크리트구조물 보강공법에 관한 것으로, 특히 항만이나 하수관과 같이 하수나 해수에 의해 콘크리트구조물의 부식으로 인한 열화된 콘크리트구조물의 보강에 사용되는 콘크리트구조물 보강용 섬유-강판 복합패널과 이의 제조방법 및 이를 이용한 콘크리트구조물 보강공법에 관한 것이다. The present invention relates to a fiber-steel composite panel for reinforcing concrete structures, a method of manufacturing the same, and a method for reinforcing concrete structures using the same, in particular, reinforcement of a degraded concrete structure due to corrosion of concrete structures by sewage or seawater, such as a harbor or sewage pipe. The present invention relates to a fiber-steel composite panel for reinforcing concrete structures, a method for manufacturing the same, and a method for reinforcing concrete structures using the same.

일반적으로 구조물은 시간 경과로 인한 노화, 재해, 설계 및 시공상의 하자, 사용변경 등 다양한 이유로 내구성, 내하력 및 구조물의 수명에 영향을 받게 되며, 구조적으로 손상된 경우에는 전면 또는 부분적인 보강조치가 요구된다. In general, a structure is affected by durability, load capacity and lifespan of the structure for various reasons such as aging, disasters, design and construction defects, and change of use over time. In case of structural damage, full or partial reinforcement measures are required. .

따라서 이러한 구조물의 보수와 보강은 구조물의 수명을 증가시키고 안전성의 확보를 위한 필수적인 과정이 된다.Therefore, repair and reinforcement of these structures is an essential process for increasing the life of the structure and ensuring safety.

특히 철근 콘크리트구조물의 경우에는 콘크리트의 중성화 또는 재료분리에 의한 박리현상, 못 또는 앵커에 의한 핀 홀 및 공극, 콘크리트의 균열 등에 의하여 구조적으로 치명적인 문제가 종종 발생한다. Particularly in the case of reinforced concrete structures, structurally fatal problems are often caused by neutralization of concrete or peeling by material separation, pin holes and pores by nails or anchors, and cracking of concrete.

이러한 구조적인 문제의 진행을 억제하고 구조물을 보강하고자 여러 가지 보수, 보강공법이 개발되고 있으며, 중요 보강공법으로는 강판접착보강공법, 탄소 섬유시트보강공법, 유리섬유시트보강공법,아라미드섬유시트보강공법 등이 적용되고 있다.Various repair and reinforcement methods have been developed to suppress the progress of these structural problems and reinforce the structure.The important reinforcement methods are steel plate adhesion reinforcement method, carbon fiber sheet reinforcement method, glass fiber sheet reinforcement method, and aramid fiber sheet reinforcement method. The construction method is applied.

강판접착공법은 보강대상 구조물을 표면처리 한 후 앵커 및 용접작업을 이용강판을 설치한 다음 밀봉하고 에폭시 수지를 주입하여 접착시키는 공법으로 재료 자체의 구입이 용이하고 재료의 확실한 성질발현을 기대할 수 있지만, 중량(소요강도를 확보하기 위해 일반적으로 4.5㎜ 이상 두께의 강판을 적용함)인 관계로 운반 및 취급상의 어려움과 시공 시 안전관리의 문제점이 있으며, 용접 등 화기의 사용으로 인하여 화재의 위험성이 있다. The steel plate bonding method is a method of surface treatment of the structure to be reinforced, anchored and welded to install the steel plate, then sealed and infused with epoxy resin to facilitate the purchase of the material itself and expression of certain properties. It is difficult to transport and handle, and there is a problem of safety management during construction because of its weight (to apply steel plate with thickness of 4.5mm or more to secure required strength), and there is a risk of fire due to the use of firearms such as welding. have.

또한, 보강 후 과다한 사하중의 증가로 인한 보강구조물의 하중부담, 강판 부식의 우려 및 내화성·내열성 등 취약한 열적 성능과 같은 문제점이 있다. In addition, there are problems such as load burden of the reinforcing structure due to the excessive increase in dead load after reinforcement, fear of steel plate corrosion, and poor thermal performance such as fire resistance and heat resistance.

탄소 섬유시트보강공법, 유리섬유시트보강공법 및 아라미드 섬유시트보강공법은 보강대상 구조물을 표면처리 한 후, 프라이머를 도포하고 에폭시 퍼티제를 이용 표면을 평면작업 한 후 에폭시 수지(접착 함침용)를 사용하여 섬유시트(탄소 섬유시트, 유리섬유시트, 아라미드 섬유시트)를 구조물에 접착시켜 시공하는 공법이다. Carbon fiber sheet reinforcing method, glass fiber sheet reinforcing method, and aramid fiber sheet reinforcing method are used to surface-reinforce the structure to be reinforced, apply primer and plan the surface using epoxy putty and then epoxy resin (for adhesive impregnation). It is a method of attaching and constructing a fiber sheet (carbon fiber sheet, glass fiber sheet, aramid fiber sheet) to the structure.

이러한 섬유시트를 이용한 보강공법은 높은 인장 강도와 탄성계수, 경량, 운 반 및 취급의 용이성 등의 장점이 있으나, 그 보강 효과 및 성능실현이 현장 기능인력에 의한 의존도가 너무 높다는 단점이 있다. The reinforcement method using the fiber sheet has advantages such as high tensile strength, modulus of elasticity, light weight, ease of handling and handling, but has a disadvantage in that the reinforcement effect and performance realization are highly dependent on the workforce.

또한, 적정의 보강 강도를 확보하기 위해 수차례에 걸친 번거로운 적층 작업이 필요하다는 점과 내화성 및 내열성에 취약하다는 점, 그리고 휨 균열이 생긴 부위의 휨 보강에는 전술하는 강판접착공법에 비해 비효율적이라는 단점이 있다.In addition, several cumbersome lamination operations are required to secure proper reinforcement strength, and they are vulnerable to fire resistance and heat resistance, and that they are inefficient compared to the above-described steel plate bonding method in flexural reinforcement at sites where bending cracks are generated. There is this.

이에, 상기한 바와 같은 제문제점을 해결하기 위해 등록특허 제10-043379호 콘크리트구조물 보강용 복합패널 및 이를 이용한 콘크리트구조물 보강공법이 제안되었다.Thus, in order to solve the problems as described above, a composite panel for reinforcing concrete structures and a concrete structure reinforcing method using the same have been proposed.

상기한 콘크리트구조물 보강용 복합패널은 도 1에 도시된 바와 같이, 일정크기의 강판(10); 상기 강판(10) 상부면에 형성되는 함침접착층(20'); 상기 강판(10)의 상부면에 설치되어 함침접착층(20')에 의해 함침, 접착되는 보강섬유(30); 및 상기 강판(10) 상부면에 분사되어 함침접착층(20') 표면에 함침, 접착되는 분말(40)을 포함함을 특징으로 한다.The composite panel for reinforcing the concrete structure, as shown in Figure 1, the steel plate 10 of a certain size; An impregnation adhesive layer 20 'formed on an upper surface of the steel plate 10; A reinforcing fiber 30 installed on an upper surface of the steel plate 10 to be impregnated and adhered by an impregnation adhesive layer 20 '; And a powder 40 sprayed on the upper surface of the steel sheet 10 to be impregnated and adhered to the surface of the impregnation adhesive layer 20 '.

또한, 상기한 콘크리트구조물 보강용 복합패널을 이용한 콘크리트구조물 보강공법은 보강대상 구조물의 바탕면(500)을 정리하는 제1단계; 상기 보강대상 구조물의 바탕면(500)과 제1항 또는 제2항의 콘크리트구조물 보강용 복합패널의 일표면에 접착층(20)을 형성시키는 제2단계 및 상기 보강대상 구조물의 바탕면(500)에 상기 콘크리트구조물 보강용 복합패널을 접착시키는 제3단계를 포함함을 특징으로 한다.In addition, the concrete structure reinforcement method using the composite panel for the concrete structure reinforcement is a first step of arranging the base surface 500 of the structure to be reinforced; On the base surface 500 of the structure to be reinforced and the second step of forming an adhesive layer 20 on one surface of the composite panel for reinforcing the concrete structure of claim 1 or claim 2 and the base surface 500 of the structure to be reinforced And a third step of adhering the composite panel for reinforcing the concrete structure.

상기한 바와 같은 구성 및 단계로 이루어진 종래의 콘크리트구조물 보강용 복합패널 및 이를 이용한 콘크리트구조물 보강공법은 기존 섬유강화플라스틱 보강공법의 단점을 보완한 것으로, 보강대상 구조물과의 일체화를 위해 접착제뿐만 아니라 앵커의 사용을 가능하게 함으로써 보강재가 탈락하지 않는 특징이 있다.The conventional composite panel for reinforcing concrete structures and the concrete structure reinforcing method using the same, which is composed of the above-described configuration and steps, complement the disadvantages of the existing fiber-reinforced plastic reinforcing method. By enabling the use of the reinforcement is characterized by not falling off.

그러나 상기한 종래의 콘크리트구조물 보강용 복합패널은 내부 강판을 통상 전기아연도금강판을 사용하고 있는데, 일반적인 환경하에서는 소요의 내부식성을 제공하고 있으나, 중화학 공업단지, 해양 환경, 접안시설의 비말대 등에서는 부식에 취약한 단점이 있으며, 작용하중의 증가시 강판과의 접착부가 박리되는 현상이 발생하기도 한다. However, the above-described conventional composite panel for reinforcing concrete structures generally uses an internal galvanized steel sheet as an internal steel sheet, but provides corrosion resistance in a general environment, but in heavy chemical industrial complexes, marine environments, eyepieces, etc. Has the disadvantage of being vulnerable to corrosion, and sometimes the adhesive portion with the steel sheet peels off when the working load increases.

또한, 복합패널에 앵커설치를 위해 천공을 하고 있는데, 이때 복합패널 내의 강판이 일부 노출되어 부식될 위험이 상존하며, 상기한 종래의 콘크리트구조물 보강용 복합패널의 절단부도 강판 노출로 인하여 부식의 위험에 직면하고 있다.In addition, there is a perforation for anchor installation in the composite panel, at this time there is a risk that the steel plate in the composite panel is partially exposed to corrosion, the risk of corrosion due to the exposure of the steel sheet also exposed to the cut portion of the conventional composite panel for reinforcing concrete structures Face to face.

그리고 상기한 종래의 콘크리트구조물 보강용 복합패널의 고정은 정착용 앵커를 돌출형 너트에 의하여 고정하고 있으나, 현장에서의 정밀시공이 이루어지지 않을 경우에는 돌출형 너트 부위가 염해 등에 노출됨으로 인하여 부식의 위험을 안고 있다. And the fixing of the conventional composite panel for reinforcing concrete structure is fixed to the anchor anchor by the protruding nut, but when the precision construction is not done in the field, the protruding nut part is exposed to salt, etc. There is a danger.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로서, 콘크리트구조물 보강에 사용되는 섬유-강판 복합패널의 강판의 내부식성을 증가시키고, 수지접착제의 접착성능을 강화하여 부식인자의 침투를 방지함과 동시에 섬유-강판 복합패널의 강판이 노출되는 단부 및 천공홀 천공부위 및 앵커 정착용 너트의 부식을 원천적으로 방지하도록 한 콘크리트구조물 보강용 섬유-강판 복합패널과 이의 제조방법 및 이를 이용한 콘크리트구조물 보강공법을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, to increase the corrosion resistance of the steel sheet of the fiber-steel composite panel used to reinforce the concrete structure, and to strengthen the adhesive performance of the resin adhesive of the corrosion factor Fiber-steel composite panel for reinforcing concrete structures and its manufacturing method which prevents penetration and at the same time prevents corrosion of the end of the steel plate of the fiber-steel composite panel and the hole at the drilled hole and anchor fixing nut The purpose is to provide a concrete structure reinforcement method used.
