Description

에폭시와 탄소섬유쉬트를 합성하여 성형된 에폭시-탄소섬유 보강판재 및 그 제조방법Epoxy-carbon fiber reinforced plate material formed by synthesizing epoxy and carbon fiber sheet and manufacturing method thereof

본 발명은 에폭시와 탄소섬유쉬트를 합성하여 성형된 에폭시-탄소섬유 보강판재 및 그 제조방법에 관한 것으로, 특히 철근 콘크리트조의 슬래브, 보 등의 구조부재가 안전성에 문제가 있을 경우에 보강시공을 용이하게 실시할 수 있도록 하기 위해 에폭시와 탄소섬유쉬트를 미리 합성하여 성형된 에폭시-탄소섬유 보강판재 및 그 제조방법에 관한 것이다.The present invention relates to an epoxy-carbon fiber reinforcement plate formed by synthesizing epoxy and carbon fiber sheet, and a method for manufacturing the same. In particular, when structural members such as slabs and beams of reinforced concrete tubing have safety problems, reinforcement is easy. The present invention relates to an epoxy-carbon fiber reinforcing plate material and a method for manufacturing the epoxy and carbon fiber sheets which are pre-synthesized in order to be able to be carried out.

일반적으로 탄소섬유쉬트를 이용한 부착공법은 접착제인 액상 에폭시 수지를 이용하여 보강하고자 하는 부위에 탄소섬유쉬트를 직접 부착시켜 내력을 확보하는 방법으로, 탄소섬유의 탁월한 인장성능이 알려진 이후에 이러한 방법은 널리 이용되고 있다. 이러한 방법은 강판보강법과 비교하여 탄소섬유쉬트 자체의 경량성, 공사의 편리성, 시공기간의 절감 등의 효과로 최근에 비교적 많이 검토되고 있다.In general, the attachment method using a carbon fiber sheet is a method of securing strength by attaching a carbon fiber sheet directly to a portion to be reinforced using a liquid epoxy resin as an adhesive. It is widely used. Compared to the steel sheet reinforcement method, such a method has been comparatively studied in recent years due to the effect of light weight of carbon fiber sheet itself, convenience of construction, and reduction of construction period.

도1은 이러한 종래의 탄소섬유 부착공법을 설명하기 위한 도면이다.1 is a view for explaining the conventional carbon fiber attachment method.

도1에 도시된 바와 같이 종래의 탄소섬유 부착공법은 먼저 바탕처리면을 형성한 다음, 프라이머 도포면을 형성하고, 이 형성한 도포면이 경화되기를 대기한다. 이 대기 시간은 약 7∼8시간이다. 그리고, 평활도를 높이기 위해 평활수정면을 형성하고, 탄소섬유 접착용 에폭시 수지를 바른 다음, 탄소섬유를 접착한다. 그리고, 약7∼8시간 동안 경화되기를 기다린 다음, 탄소섬유쉬트를 원하는 수만큼 반복하여 부착한다. 이것이 완료되면 내화 도료등으로 마감처리를 한다.As shown in FIG. 1, the conventional carbon fiber attachment method first forms a base treatment surface, and then forms a primer coating surface, and waits for the formed coating surface to harden. This waiting time is about 7-8 hours. Then, in order to increase the smoothness, a smooth water surface is formed, the epoxy resin for carbon fiber adhesion is applied, and then the carbon fiber is bonded. After waiting for curing for about 7 to 8 hours, the carbon fiber sheet is repeatedly attached as many times as desired. When this is done, finish with a fireproof paint.

이와 같은 종래의 공법은 시공후 구조물을 정상적으로 사용하기까지 프라이머 도포후 7일, 탄소섬유쉬트 부착후 7일등 최소한 14일 이상의 경화대기시간이 필요하게 된다.Such a conventional method requires a curing waiting time of at least 14 days, such as 7 days after the primer is applied and 7 days after the carbon fiber sheet is attached until the structure is normally used after construction.

또한, 종래의 탄소섬유쉬트 현장부착공법은 보강설계시 기준이 되는 정확한 부착두께의 확보가 어렵다는 점과 액상 에폭시 수지의 점도가 적절하지 않을 경우 흘러내리거나, 부착후 내력증진에 대한 검증실험이 어렵다는 문제점이 있었다. 이 뿐만 아니라, 보강하고자 하는 구조물이 슬래브, 보 등일 때 그 하부에서 상부쪽을 향해 부착작업을 실시하여야 하는 이유로 작업자들이 시공하는데 매우 어렵고, 보강작업이 대부분 교량의 하부, 지하층등 수분이 많이 존재하는 공간의 콘크리트 표면이기 때문에 액상 에폭시의 경화 지연등으로 인해 품질이 저하되고, 보강성능의 신뢰성이 저하되는 문제점이 있었다.In addition, the conventional carbon fiber sheet field attachment method is difficult to secure the exact thickness of the reference when reinforcing design, and if the viscosity of the liquid epoxy resin is not appropriate, it is difficult to verify the flow test, or to increase the strength after attachment. There was a problem. In addition, when the structure to be reinforced is a slab, beam, etc., it is very difficult for the workers to construct it because it needs to be attached from the lower part to the upper part. Because of the concrete surface of the space, there is a problem that the quality is lowered due to the curing delay of the liquid epoxy, and the reliability of the reinforcing performance is lowered.

따라서, 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 본 발명은, 철근 콘크리트조의 슬래브, 보 등의 구조부재 보강시 시공이 용이하고, 비용 절감 및 공기를 단축시킬 수 있는 에폭시와 탄소섬유쉬트를 미리 합성하여 성형된 에폭시-탄소섬유 보강판재 및 그 제조방법을 제공하는데 그 목적이 있다.Therefore, the present invention devised to solve the problems of the prior art as described above, it is easy to construct when reinforcing structural members, such as slabs, beams of reinforced concrete, epoxy and carbon fiber sheet that can reduce the cost and shorten the air The purpose is to provide an epoxy-carbon fiber reinforcing plate and a method for producing the molded by synthesizing in advance.

이하, 첨부된 도2 내지 도5를 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 to 5.

도2는 본 발명에 이용되는 탄소섬유쉬트(4)의 단면도를 나타낸다.2 shows a cross-sectional view of the carbon fiber sheet 4 used in the present invention.

일반적으로 탄소섬유쉬트(4)는 쉬트보호지(3)위에 보호직물(2)이 형성되고, 이 보호직물(2)위에는 탄소섬유뭉치(1)들이 수평방향으로 배열된다.In general, the carbon fiber sheet 4 is a protective fabric (2) is formed on the sheet protective paper (3), the carbon fiber bundle (1) is arranged in a horizontal direction on the protective fabric (2).

도3은 본 발명에 따른 에폭시-탄소섬유 보강판재의 외관도를 나타내고, 도4는 도3의 A-A'부분의 단면도를 나타낸다.Figure 3 shows an external view of the epoxy-carbon fiber reinforcing plate according to the present invention, Figure 4 shows a cross-sectional view of the AA 'portion of FIG.

본 발명에 따른 에폭시-탄소섬유 보강판재는 탄소섬유쉬트(4)의 쉬트보호지(3)를 제거한 후, 탄소섬유쉬트의 상하면에 에폭시 수지층(5, 6)을 형성함으로써 제조된다.The epoxy-carbon fiber reinforcing plate material according to the present invention is prepared by removing the sheet protective paper 3 of the carbon fiber sheet 4 and then forming the epoxy resin layers 5 and 6 on the upper and lower surfaces of the carbon fiber sheet.

즉, 본 발명에 따른 에폭시-탄소섬유 보강판재는 에폭시 수지를 이용해 경화시켜 형성된 하부판재(5)와, 상기 하부판재(5)의 상부에 부착되는 탄소섬유쉬트(4), 및 상기 탄소섬유쉬트(4) 상부에 에폭시 수지를 이용해 경화시켜 형성된 상부판재(6)로 구성된다.That is, the epoxy-carbon fiber reinforcing plate according to the present invention is a lower plate member 5 formed by curing using an epoxy resin, a carbon fiber sheet 4 attached to the upper portion of the lower plate member 5, and the carbon fiber sheet (4) It consists of the upper board material 6 formed by hardening using an epoxy resin in the upper part.

본 발명의 바람직한 실시예에 따르면 본 발명의 보강판재 1장의 두께는 탄소섬유쉬트(4)의 보강겹침수가 1장일 경우 약3mm정도가 된다. 즉, 에폭시 수지 상,하부판재(5, 6)의 두께는 각각 약1.3mm이고, 탄소섬유쉬트(4)의 두께는 약0.4mm정도이다. 탄소섬유쉬트의 보강겹침수가 1장이 증가하면 1장 두께의 약2배 두께로 증가된다.According to a preferred embodiment of the present invention, the thickness of one sheet of reinforcing plate of the present invention is about 3 mm when the number of reinforcing layers of the carbon fiber sheet 4 is one sheet. That is, the thickness of the upper and lower plate materials 5 and 6 of the epoxy resin is about 1.3 mm, respectively, and the thickness of the carbon fiber sheet 4 is about 0.4 mm. If the number of reinforcing layers of carbon fiber sheet is increased by one sheet, the thickness increases to about twice the thickness of one sheet.

도5는 이러한 본 발명의 에폭시-탄소섬유 보강판재의 제조방법을 나타내는 설명도이다.5 is an explanatory view showing a method of manufacturing the epoxy-carbon fiber reinforcing plate of the present invention.

도5에 도시된 바와 같이 보강판재의 하부부분을 형성하기 위해 약1.3mm정도를 에폭시 수지로 채워서 일정 시간동안 경화시킨다(101).As shown in Figure 5 to form a lower portion of the reinforcing plate filled with about 1.3mm epoxy resin and cured for a predetermined time (101).

그리고, 이 경화시켜 형성된 하부판재의 위에 탄소섬유쉬트(4)를 적층하고, 에폭시 수지가 묻혀진 회전 로울러를 상기 적층된 탄소섬유쉬트의 상부를 소정의 회수동안 문질러 충분히 함침되도록 강압한 다음(102), 나머지 에폭시 수지를 부어 상부판재를 형성한다(103).Then, the carbon fiber sheet 4 is laminated on the cured lower plate member, and a rotary roller embedded with an epoxy resin is pressed down to sufficiently impregnate the upper part of the laminated carbon fiber sheet by a predetermined number of times (102). Then, the remaining epoxy resin is poured to form a top plate (103).

그런 다음, 보강판재의 두께를 조절하기 위해 상부판재에 에폭시 수지를 추가로 투입하여 두께를 조정한 후, 이를 경화시킨다(104). 그리고, 경화가 완료되면 탈형하고 소정의 크기로 재단하여 보강판재를 완성한다(105).Then, in order to adjust the thickness of the reinforcing plate material by further adding an epoxy resin to the upper plate material to adjust the thickness, it is cured (104). Then, when the curing is completed, the mold is demoulded and cut into a predetermined size to complete the reinforcing plate material (105).

이때, 상부판재의 두께 조절은 미리 눈금을 표시하여 조절한다.At this time, the thickness of the upper plate is adjusted by displaying the scale in advance.

본 발명의 에폭시-탄소섬유 보강판재를 제작할 때 가장 중요한 사항은 판재의 중앙부에 삽입되는 탄소섬유쉬트의 탄소섬유뭉치(1)에 에폭시 수지가 균일하게 함침되는 것이다. 즉, 일반적으로 탄소섬유뭉치(1) 1개에 수백개의 탄소섬유단사가 배열되어 있기 때문에 배열되어 있는 탄소섬유단사 사이사이로 에폭시 수지가 함침되어야 탄소섬유쉬트 전체가 하나로 되어 제 성능을 발휘할 수 있다.The most important thing in producing the epoxy-carbon fiber reinforcing plate of the present invention is that the epoxy resin is uniformly impregnated with the carbon fiber bundle 1 of the carbon fiber sheet inserted into the center of the plate. That is, in general, hundreds of carbon fiber yarns are arranged in one carbon fiber bundle 1, so that the entire carbon fiber sheet can be exhibited in one performance only when the epoxy resin is impregnated between the arranged carbon fiber yarns.

따라서, 본 발명에서는 이를 위해 에폭시 수지를 탄소섬유쉬트를 기준으로 상·하로 분리하였다. 먼저, 에폭시 수지를 투입하여 어느 정도 경화가 시작되면 그 상부에 로울러 등을 이용하여 탄소섬유쉬트를 적층시키고, 다시 그 상부에 에폭시 수지 일부를 투입하여 함침시키는 것이다. 이렇게 하면 먼저 경화된 에폭시 층이 받침대(작업대) 역할을 하여 탄소섬유쉬트의 함침 작업이 용이하게 된다.Therefore, in the present invention, for this purpose, the epoxy resin was separated up and down on the basis of the carbon fiber sheet. First, when curing is started to some extent by adding an epoxy resin, the carbon fiber sheet is laminated using a roller or the like on top thereof, and then a part of the epoxy resin is impregnated into the top of the epoxy resin. This facilitates the impregnation of the carbon fiber sheet, with the first cured epoxy layer acting as a pedestal.

판재를 공장에서 제작할 시 하부판재를 별도로 성형하여 함침시켜도 무방하다. 이런 공정을 통해 탄소섬유쉬트의 함침성능이 향상되고, 판재의 소요성능이 보장되는 것이다.When the plate is manufactured at the factory, the lower plate may be separately formed and impregnated. Through this process, the impregnation performance of the carbon fiber sheet is improved, and the required performance of the sheet is guaranteed.

상기와 같이 이루어진 본 발명에 따른 효과를 살펴보면 다음과 같다.Looking at the effect of the present invention made as described above are as follows.

본 발명에 의하면 현장에서 보강판재 부착시 경화대기 시간이 불필요하고, 보강공정이 단순하여 비용이 절감되는 효과가 있다. 본 발명에 따른 보강판재를 이용하는 경우의 비용 절감정도를 살펴보면, 본 발명에 의한 보강공법은 종래의 공법에 비해 재료비 저감효과는 13%, 인건비 저감효과는 46%, 전체적인 시공비 저감효과는 29% 정도인 것으로 파악되었다.According to the present invention, when the reinforcing plate is attached in the field, curing waiting time is unnecessary, and the reinforcing process is simple, thereby reducing the cost. Looking at the degree of cost reduction when using the reinforcing plate according to the present invention, the reinforcement method according to the present invention is 13%, the labor cost reduction effect is 46%, the overall construction cost reduction effect is about 29% compared to the conventional method Was found to be.

또한, 본 발명의 에폭시-탄소섬유 보강판재는 보강시공이 편리하고, 보강시 에폭시 수지의 흘러내림 현상이나 수분에 의한 에폭시 수지의 접착 성능저하 현상을 개선시킬 수 있어, 시공품질을 향상시킬 수 있는 효과가 있다.In addition, the epoxy-carbon fiber reinforcing plate material of the present invention is convenient to reinforcement construction, and can improve the falling performance of the epoxy resin during the reinforcement or degradation of the adhesion performance of the epoxy resin due to moisture, thereby improving the construction quality It works.
