본 발명은 탄소섬유발열 금속제거푸집에 관한 것으로, 거푸집의 판부재 길이에 대응되는 길이이면서 판부재 폭의 30 내지 37.5%인 폭으로 형성된 면상구조의 두 탄소섬유발열체가 판부재 배면에 부착되되, 판부재 배면에 거푸집의 면판보강재가 용접되기 전, 판부재 폭의 양단과 가운데에서 이격되도록 부착되며, 탄소섬유발열체 배면에 위치한 면판보강재는 탄소섬유발열체가 이격된 판부재 양단과 가운데 부분의 배면에 용접되어, 전기공급과 작동제어를 하는 제어장치를 통해 판부재에 부착된 탄소섬유발열체가 발열함으로써, 판부재 배면에 부착된 탄소섬유발열체와 판부재 배면에 면판보강재를 고정하는 용접부분이 서로 간섭하지 않도록 하며, 조립된 거푸집에 콘크리트 시공 시, 탄소섬유발열체로 판부재를 가열하여 동절기 동해 방지나 콘크리트의 초기 수화시간을 단축 시킬 수 있는 탄소섬유발열 금속제거푸집에 관한 것이다.The present invention relates to a carbon fiber heating metal removal piece, wherein two carbon fiber heating elements of a planar structure formed with a width corresponding to the length of the plate member of the form and 30 to 37.5% of the width of the plate member are attached to the rear surface of the plate member, Before the face plate reinforcement of the formwork is welded to the back of the member, it is attached so as to be spaced apart from both ends and the center of the width of the plate member, and the face plate stiffener located on the back of the carbon fiber heating element is welded to both ends of the plate member separated by the carbon fiber heating element and the back of the middle part. As a result, the carbon fiber heating element attached to the plate member generates heat through a control device that supplies electricity and controls the operation, so that the carbon fiber heating element attached to the rear surface of the plate member and the welding part fixing the face plate reinforcement on the rear surface of the plate member do not interfere with each other. When constructing concrete on the assembled formwork, it relates to a carbon fiber heating metal removal work that can prevent freezing in winter or shorten the initial hydration time of concrete by heating a plate member with a carbon fiber heating element.

일반적으로 거푸집이란 판부재와, 판부재 테두리를 따라 배면으로 돌출되도록 구성된 측면보강재, 판부재 배면에서 일정길이간격으로 구성된 면판보강재로 구성된다.In general, the formwork is composed of a plate member, a side stiffener configured to protrude to the rear surface along the edge of the plate member, and a face plate stiffener configured at a predetermined length from the rear surface of the plate member.

여기서 판부재 및 측면보강재와 면판보강재에 따라 나무재질의 목재거푸집, 규격화된 형태의 유로폼, 알류미늄재질의 알폼, 철 재질의 철제거푸집 등으로 나누어진다.Here, according to the plate member, the side stiffener and the face plate stiffener, it is divided into a wooden form, a standardized form of a flow path, an aluminum form, and an iron removal form.

이러한 거푸집을 이용하여 콘크리트 타설 및 양생 시, 온도와 같은 환경에 따라 콘크리트의 품질 및 양생 시간이 달라지는데, 특히 특히 동절기이나 우천시와 같이 환경의 경우, 양생 시간이 더 오래 걸릴뿐더러, 동절기의 동해로 인한 콘크리트의 품질이 저하되는 문제가 있기에, 동절기 및 우천 시, 거푸집의 보온을 위한 천막이나 보양 및 난방자재 등이 많이 사용되어 왔다.The quality and curing time of concrete varies depending on the environment such as temperature when placing and curing concrete using such a formwork. Particularly, in the case of environments such as winter or rainy weather, curing time is not only taken longer, but also due to the winter damage in winter. Since there is a problem of deteriorating the quality of concrete, tents for heat insulation of the formwork and heating materials have been widely used in winter and rain.

여기서 콘크리트 시공에 사용되는 보양 및 난방자재로, 종래에는 거푸집에 함입되어 전기에 의해 발열하는 전열선, 기름과 같은 가연성 재료에 의해 가열하여 거푸집 표면을 가열하는 열풍기, 거푸집 외면에 부착되는 단열재 등이 이용되어 왔는데, 이러한 종래의 보양 및 난방자재보다 성능이나 편의성을 향상하는 기술들이 개발되고 있다.Here, as a maintenance and heating material used in concrete construction, conventionally, a heat transfer wire embedded in the formwork to generate heat by electricity, a hot air fan that heats the formwork surface by heating with a combustible material such as oil, and an insulation material attached to the outer surface of the formwork are used. It has been, but technologies for improving performance or convenience than such conventional maintenance and heating materials are being developed.

그 예로, 대한민국특허등록 제1271397호에서는 (a) 마이크로파 발생기; 상기 마이크로파 발생기로부터 마이크로파를 전달받아 하우징 내부로 전달하는 도파관; 상기 도파관으로 전달된 마이크로파를 난반사 시키는 하우징; 및 상기 난반사 되는 마이크로파를 흡수하여 열을 발생시키고 이 열에 의해 가열 대상 콘크리트의 표면을 가열하는 발열부를 포함하여 구성되며, 상기 도파관은 하우징의 외부에 연결되고 상기 발열부는 하우징의 내부에 장착되어 설치되되, 상기 발열부의 일방은 대상 콘크리트의 표면을 가열시키고 타방은 하우징 내부에 장착된 형태로 모듈화되도록 구성되고, 상기 발열부는 Fe2O3, Fe3O4 및 FeO 중 하나 이상의 산화철 화합물을 4 중량% 이상 포함하는 금속산화물 함유 조성물로 구성되는 것을 특징으로 하는 마이크로파에 의해 발열되는 발열거푸집을 시공 현장에서 교량 기초 시공용 강재 거푸집의 파티션에 설치하거나 직접 교량 기초 시공용 거푸집으로 설치하는 단계; (b) 상기 설치된 거푸집 내에 콘크리트를 타설하는 단계; (c) 상기 마이크로파에 의해 발열되는 발열 거푸집에 전원을 공급하여 발열시키는 단계; (d) 상기 타설된 콘크리트를 양생하는 단계; 및 (e) 상기 설치된 마이크로파에 의해 발열되는 발열 거푸집을 제거하는 단계를 포함하는 "마이크로파에 의해 발열되는 발열 거푸집을 이용한 콘크리트 교량 기초의 건설 방법"이 게시되어 있다. For example, in Korean Patent Registration No. 1271397, (a) a microwave generator; A waveguide receiving microwaves from the microwave generator and transmitting them into the housing; A housing for diffusely reflecting microwaves transmitted to the waveguide; And a heating unit that absorbs the diffusely reflected microwave to generate heat and heats the surface of the concrete to be heated by the heat, and the waveguide is connected to the outside of the housing, and the heating unit is installed and installed inside the housing. , One of the heating parts is configured to heat the surface of the target concrete and the other is configured to be modularized into a form mounted inside the housing, and the heating part contains a metal oxide containing 4% by weight or more of at least one iron oxide compound of Fe2O3, Fe3O4 and FeO Installing a heating formwork generated by microwaves, characterized in that consisting of a composition, on a partition of a steel formwork for bridge foundation construction at a construction site or directly as a formwork for bridge foundation construction; (b) pouring concrete into the installed formwork; (c) supplying power to the heat generating mold generated by the microwave to generate heat; (d) curing the poured concrete; And (e) removing the heat-generating formwork generated by the installed microwave.

그러나 대한민국특허등록 제1271397호의 "마이크로파에 의해 발열되는 발열 거푸집을 이용한 콘크리트 교량 기초의 건설 방법"의 경우, 마이크로파 발생기 구조적 특성 상, 거푸집 배면으로 많이 돌출되며, 이러한 마이크로파 발생기의 자체 중량에 의해 통상의 거푸집 하중계산과 달리 계산하여야 함에 구조계산과 시공이 용이하지 못한 문제점이 있었다. However, in the case of the "construction method of a concrete bridge foundation using a heating form generated by microwaves" in Korean Patent Registration No. 1271397, due to the structural characteristics of the microwave generator, it protrudes a lot from the back of the formwork. There was a problem that structural calculation and construction were not easy because it had to be calculated differently from the formwork load calculation.

또, 동절기 콘크리트의 동해를 입거나 수화반응이 늦어지는 것을 방지하기 위해 거푸집에 함입되는 전열선의 경우, 거푸집에 전열선을 함입시키는 것이 용이하지 않은데, 특히 재사용이 많은 금속제거푸집을 사용하고 재 사용 시, 연결된 전열선과 전기선이 파손될 위험이 있었다.In addition, in the case of the heating wire embedded in the formwork to prevent freezing of concrete in winter or slowing down the hydration reaction, it is not easy to insert the heating wire into the formwork. There was a risk of damage to the connected heating wire and electric wire.

또한, 동절기 콘크리트 시공 시, 열풍기를 이용하는 종래의 방법에서는, 주로 콘크리트가 타설되는 실내에 열풍기가 위치하게 됨으로써, 콘크리트가 양생되는 내벽은 열풍기에 의해 가열되나 콘크리트가 양생되는 외벽은 영하의 외기에 노출되어 동해를 입거나 수화반응이 늦어지는 문제점이 있을뿐더러, 열풍기 관리 및 가연성 재료의 관리가 소홀해 질 경우, 화재의 위험이 있었다.In addition, in the conventional method of using a hot air when constructing concrete in winter, the hot air is mainly located in the interior where the concrete is poured, so that the inner wall where the concrete is cured is heated by a hot air, but the outer wall where the concrete is cured is exposed to sub-zero outside air. As a result, there was a problem that the hydration reaction was delayed and there was a risk of fire when the management of the hot air fan and the management of combustible materials were neglected.

따라서 전술된 문제점을 해결하고자, 거푸집의 판부재 길이에 대응되는 길이이면서 판부재 폭의 30 내지 37.5%인 폭으로 형성된 면상구조의 두 탄소섬유발열체가 판부재 배면에 부착되되, 판부재 배면에 거푸집의 면판보강재가 용접되기 전, 판부재 폭의 양단과 가운데에서 이격되도록 부착되며, 탄소섬유발열체 배면에 위치한 면판보강재는 탄소섬유발열체가 이격된 판부재 양단과 가운데 부분의 배면에 용접되어, 전기공급과 작동제어를 하는 제어장치를 통해 판부재에 부착된 탄소섬유발열체가 발열함으로써, 판부재 배면에 부착된 탄소섬유발열체와 판부재 배면에 판보강재를 고정하는 용접부분이 서로 간섭하지 않도록 한다.Therefore, in order to solve the above-described problem, two carbon fiber heating elements of a planar structure formed with a width corresponding to the length of the plate member of the formwork and a width of 30 to 37.5% of the width of the plate member are attached to the back surface of the plate member. Before the face plate reinforcement of the plate member is welded, it is attached so as to be spaced from both ends and the center of the plate member width, and the face plate stiffener located on the rear surface of the carbon fiber heating element is welded to both ends of the plate member spaced apart from the carbon fiber heating element and the rear surface of the middle part to supply electricity. The carbon fiber heating element attached to the plate member generates heat through a control device that controls the operation and the carbon fiber heating element attached to the rear surface of the plate member and the welding part fixing the plate stiffener to the plate member do not interfere with each other.

또한, 탄소섬유발열체는 경사와 위사와 그라운드사를 포함하되, 경사와 위사는 탄소섬유와 폴리에스테르섬유를 포함하고, 경사와 위사의 융점보다 낮은 융점의 그라운드사가 경사와 위사를 엮도록 배치되어, 그라운드사의 융점 사이의 온도로 그라운드사를 융착 시킴으로써, 탄소섬유발열체의 원단 공극을 줄이도록 한다.In addition, the carbon fiber heating element includes warp, weft and ground yarn, but the warp and weft include carbon fiber and polyester fiber, and the ground yarn of a melting point lower than the melting point of the warp and weft is arranged to weave the warp and weft, By fusing the ground yarn at a temperature between the melting point of the ground yarn, it is possible to reduce the air gap of the carbon fiber heating element.

이와 같이, 본 발명의 탄소섬유발열 금속제거푸집은 동절기 콘크리트 시공 시, 탄소섬유발열체에 의해 판부재가 균일하게 가열되어 동해를 방지하며, 콘크리트의 초기 수화시간을 단축시킬 수 있을뿐더러, 면상구조의 탄소섬유발열체가 판부재에 면판보강재가 용접되기 전에 부착되고, 탄소섬유발열체가 부착되지 않은 판부재 배면에 면판보강재가 용접됨으로써, 용접부분과 탄소섬유발열체의 간섭을 피하여 탄소섬유발열체의 파손을 방지할 수 있는 효과가 있으며, 탄소섬유발열체가 판부재와 면판보강재 사이에 구성됨으로써, 탄소섬유발열체의 이탈을 방지하는 효과가 있다.As described above, the carbon fiber heating metal removal piece of the present invention prevents freezing by uniformly heating the plate member by the carbon fiber heating element when constructing concrete in winter, and shortens the initial hydration time of the concrete. The fiber heating element is attached to the plate member before the face plate reinforcement is welded, and the face plate reinforcement is welded to the back of the plate member to which the carbon fiber heating element is not attached, thereby avoiding interference between the welding part and the carbon fiber heating element, thereby preventing damage to the carbon fiber heating element. The carbon fiber heating element is formed between the plate member and the face plate stiffener, thereby preventing the carbon fiber heating element from being separated.

또한, 구성되는 탄소섬유발열체는 금속제인 판부재에 밀착됨으로써, 균일하게 온도상승을 시켜주며, 면상구조의 탄소섬유발열체가 사용됨으로써, 통상의 거푸집과 외형과 무게에서 큰 차이가 없어 사용이 용이한 효과가 있다.In addition, the composed carbon fiber heating element is in close contact with a metal plate member to increase the temperature uniformly, and by using a planar structure carbon fiber heating element, there is no significant difference in appearance and weight from the ordinary formwork, making it easy to use. It works.

그리고 본 발명에 구성되는 탄소섬유발열체는 경사와 위사를 엮도록 배치된 그라운드사가 경사와 위사보다 융점이 낮아 그라운드사만 용융시켜 경사와 위사를 융착시킬수 있어, 탄소섬유발열체 원단의 공극을 줄일수 있는 효과가 있다. In addition, the carbon fiber heating element configured in the present invention has a lower melting point than that of the warp and weft yarns, so that only the ground yarns are melted to fuse the warp and weft yarns, thereby reducing the voids of the fabric of the carbon fiber heaters. It works.

As a result, the carbon fiber heating element attached to the plate member generates heat through a control device that supplies electricity and controls the operation, so that the carbon fiber heating element attached to the rear surface of the plate member and the welding part fixing the face plate reinforcement on the rear surface of the plate member do not interfere with each other. When constructing concrete on the assembled formwork, it relates to a carbon fiber heating metal removal work that can prevent freezing in winter or shorten the initial hydration time of concrete by heating a plate member with a carbon fiber heating element.

본 발명의 탄소섬유발열 금속제거푸집은 거푸집 구성인 판부재와 측면보강재와 면판보강재에 탄소섬유발열체가 추가로 구성되는데, 이를 설명하면 다음과 같다.The carbon fiber heating metal removal piece of the present invention further includes a carbon fiber heating element in a plate member, a side stiffener, and a face plate stiffener, which are formwork configurations, which will be described as follows.

먼저, 금속제거푸집(100)은 상하로 길이가 긴 사각형의 금속제 판부재(111)와, 이 판부재(111) 테두리를 따라 배면으로 돌출 구성되는 금속제 측면보강재(112)와, 판부재(111) 배면에 수평방향으로 일정길이간격 구성되는 금속제 면판보강재(113)를 포함하는 통상의 거푸집 구조이다.First, the metal removal piece 100 includes a rectangular metal plate member 111 having a long vertical length, a metal side stiffener 112 configured to protrude to the rear surface along the edge of the plate member 111, and a plate member 111 It is a conventional formwork structure including a metal face plate stiffener 113 configured at a constant length interval in the horizontal direction on the rear surface.

그리고 탄소섬유발열체(121)는 판부재(111)의 길이에 대응되는 길이의 면상구조로 판부재(111)에 부착되는 탄소섬유발열체(121)가 하나일 경우, 하나의 탄소섬유발열체(121)의 폭은 판부재(111) 폭의 60 내지 75%의 폭(바람직하게는 판부재 폭의 2/3폭)으로 형성되며, 판부재(111)에 부착되는 탄소섬유발열체(121)가 두개일 경우, 각각의 탄소섬유발열체(121)의 폭은 판부재(111) 폭의 30 내지 37.5%의 폭(바람직하게는 판부재 폭의 1/3폭)으로 형성된다.And the carbon fiber heating element 121 has a planar structure having a length corresponding to the length of the plate member 111, and when there is one carbon fiber heating element 121 attached to the plate member 111, one carbon fiber heating element 121 The width of the plate member 111 is formed with a width of 60 to 75% of the width (preferably 2/3 of the width of the plate member), and the carbon fiber heating element 121 attached to the plate member 111 is two. In this case, the width of each carbon fiber heating element 121 is formed to be 30 to 37.5% of the width of the plate member 111 (preferably 1/3 the width of the plate member).

또한, 판부재(111)에 부착되는 탄소섬유발열체(121)가 다수 개일 경우, 부착되는 탄소섬유발열체(121) 폭의 총 합이 판부재(111) 폭의 60 내지 75%(바람직하게는 판부재 폭의 2/3폭)이 되도록 형성된다. In addition, when there are multiple carbon fiber heating elements 121 attached to the plate member 111, the total sum of the widths of the attached carbon fiber heating elements 121 is 60 to 75% of the width of the plate member 111 (preferably the plate 2/3 of the width of the member).
