Description

건축용 보강재 및 그 제조방법과 장치{Reinforcement for construction and manufacturing process and apparatus}Construction reinforcement and its manufacturing method and apparatus {Reinforcement for construction and manufacturing process and apparatus}

본 발명은 건축물 및 토목공사 또는 건축물의 보수, 보강공사에서의 콘크리트몰탈 보강재를 얻기 위한 건축용 보강재 및 그 제조방법과 장치에 관한 것이다.The present invention relates to a building reinforcement for obtaining concrete mortar reinforcement in buildings and civil works or repair, reinforcement work, and a method and apparatus for manufacturing the same.

일반적으로 건축물 및 토목공사 또는 보수, 보강공사(이하 공사라 함)는 주지하는 바와 같이 철근으로 보강지지부를 형성하고 이 보강부 외측으로 거푸집에 의한 벽 등의 일정한 형태를 구성하여 콘크리트 몰탈을 충진과 함께 양생시키게 되며 양생후 거푸집을 제거함으로 벽 등이 구성되고 상기 철근으로 이루어지는 보강부재는 양생된 몰탈의 지지력을 보강하여 견고한 벽체를 얻게 되는 것이다.In general, building, civil engineering, or repair and reinforcement work (hereinafter referred to as “reinforcement”) forms reinforcement support parts with reinforcing bars and forms a certain shape such as walls by formwork outside the reinforcement parts to fill concrete mortar with Curing together and by removing the formwork after curing, the wall is configured and the reinforcing member made of the reinforcement is to obtain a solid wall by reinforcing the supporting force of the cured mortar.

상기 보강부재의 철근(鐵筋, steel reinforcement)은 철근콘크리트에 쓰이는 보강근(補强筋). 원형철근(圓形鐵筋)과 이형철근(異形鐵筋)으로 나누어지고 있으며 종류와 치수·재질 등은 KSD 3504(철근 콘크리트용 봉강)에 규정되어 있고 또한 철근의 길이는 따로 주문하지 않는 한 3.5~10.0 m까지 생산되며 미끄럼 방지의 마디와 리브(rib)가 있다. 이러한 이유는 콘크리트와의 부착력이 크며 콘크리트에 균열이 생길 때는 균열 폭이 작아지는 특징을 발휘할 수 있도록 한 것이다.Reinforcing steel (鐵 筋, steel reinforcement) of the reinforcing member is used for reinforcement concrete (補 强筋). It is divided into circular reinforcement and deformed reinforcing bar. Kinds, dimensions, and materials are specified in KSD 3504 (bars for reinforced concrete), and the length of rebars is 3.5. Produces up to ~ 10.0 m with non-slip knuckles and ribs. The reason for this is that the adhesion with the concrete is great and the crack width becomes smaller when the crack occurs in the concrete.

이러한 철근은 쉽게 녹이 발생되어 녹으로 인한 철근의 강도저하를 야기하고 그 설치지점이 물 또는 습기와 염분이 많은 곳에서는 녹발생이 급격히 증가되어 건축물의 수명을 크게 단축하는 단점을 가기고 있다.These reinforcing bars are easily rusted, which causes the strength of the reinforcing bars to be rusted, and the occurrence of rust is rapidly increased in places where water or moisture and salts are installed.

또한 철을 주재로 하는 철근은 국내의 자원 조달이 이루어지지 못함으로 고가이고 중량이 무거워 운반 및 보관에 많은 문제점을 가지고 있는 것이다.In addition, rebars based on iron have many problems in transportation and storage because they are expensive and heavy because domestic resources cannot be obtained.

이와 같은 문제점을 개선하기 위하여 대한민국 공개특허공보 1997년 제 25928호에서는 물과 염분에 강하고 저렴한 생산가로 대량 생산될 수 있는 탄소섬유와 수지로 구성된 보강재가 알려지고 있다.In order to improve such a problem, Republic of Korea Patent Publication No. 25928 No. 1997 is known that a reinforcing material composed of carbon fiber and resin that can be mass-produced at low cost and strong in water and salt.

상기 선 발명은 금형 내에서 탄소섬유층을 적층시켜 가열 가압에 의한 진공성형으로 보강판재를 구성함으로서 견고성을 높이는 한편 물과 습기 및 염분에 강하고 또한 저렴한 보강재를 제공한 바있다.The above-described invention has provided a reinforcing material which is strong against water, moisture, and salt while increasing the robustness by forming a reinforcing plate member by laminating a carbon fiber layer in a mold to form a vacuum by heating and pressing.

상기에서 보강판과 함께 봉재를 성형함으로서 콘크리트몰탈층내에 심어지는 심재로서 이용되고도 있다.It is also used as a core material planted in the concrete mortar layer by forming a bar together with the reinforcing plate.

이러한 발명에서의 심재는 탄소섬유사를 다수겹 적층시켜 금형에 의해 성형되는 것으로서 제작이 어려운 문제와 함께 특히 섬유사로 구성된 심재의 외주면이 매끄러워 구성물에서 힘을 받게 되면 심재가 몰탈층에서 슬립되어 빠지는 폐단 즉, 미끄럼이 발생하게 되어 몰탈증을 견고히 부착시킬 수 없는 단점을 가지고 있는 것이다.In this invention, the core material is formed by laminating a plurality of layers of carbon fiber yarn, which is difficult to manufacture. In particular, when the outer circumferential surface of the core material made of fiber yarn is smooth and is subjected to strength in the composition, the core material slips off the mortar layer. Closing, that is, the slip is generated is a disadvantage that can not be firmly attached to mortar.

본 발명은 상기와 같은 종래의 제반 문제점들을 개선하기 위하여 안출된 것으로서 특히 심재용 섬유를 조방(Roving)한 후, 경화제와 선택적으로 첨가하는 안료 등이 적당량 혼합된 수지가 보관된 함침조에 함침시키고, 수지가 함침된 심재를 가호(Sizing)처리하면서 경화시켜 다시 수지층을 형성하여 가넷(30)코팅처리하여 예열히팅에 의한 경화와 인발후 일정크기로 절단하는 공정으로 건축용 보강재의 봉재를 구성함으로서 강도와 탄성회복성이 우수하고 전파투과성 및 내약강성이 강하고 소망하는 균일한 굵기를 가지며, 특히 가넷에 의한 미끄럼방지효과를 증대하여 건축용 보강봉재로 사용하여 건축물의 견고성과 함께 물이나 염분에 강한 부재를 제공함을 목적으로 한 발명이다.The present invention has been made in order to improve the above-mentioned conventional problems, in particular, after roving the core fiber (impregnated), the impregnating tank in which a suitable amount of a mixed amount of a hardener and a pigment selectively added, such as impregnated in the impregnation tank, and the resin The hardened impregnated core material is cured while sizing, and the resin layer is formed again, and the garnet 30 is coated to harden by preheating and cut to a certain size after drawing. It has excellent elastic recovery, strong radio transmission and weak resistance, and has the desired uniform thickness.In particular, it is used as a reinforcing rod for building by increasing the anti-slip effect by garnet, providing a strong member against water and salt along with the strength of the building. The invention is for the purpose.
