Description

터널공사의 콘크리트 양생을 위한 가열장치 {A heater for cure the concreted surface of Tunneling work}Heater for curing concrete in tunnel construction {A heater for cure the concreted surface of Tunneling work}

본 발명은 콘크리트를 양생하기 위한 가열장치에 관한 것으로 더욱 자세하게는, 각종 건축공사와 토목공사 그리고 특히 터널공사에서 거푸집을 통해 타설된 콘크리트를 신속하게 양생시키기 위해 거푸집 외측으로 가열판을 설치하여 신속하게 양생시켜 공사기간을 단축시키며 공사비용을 절감할 수 있는 터널공사의 콘크리트 양생을 위한 가열장치에 관한 것이다.The present invention relates to a heating apparatus for curing concrete, and more particularly, to quickly cure by installing a heating plate outside the formwork to quickly cure concrete poured through the formwork in various construction works, civil works and tunnel construction in particular. The present invention relates to a heating device for concrete curing of tunnel construction that can shorten the construction period and reduce construction costs.

잘 알려진 바와 같이 건축공사와 토목공사 등에서 콘크리트를 타설하기 위해서는 거푸집이 설치되고 상기 거푸집 내측으로 콘크리트가 타설된 다음 상기 콘크리트가 양생될 시간이 소요된다.      As is well known, in order to pour concrete in construction work and civil engineering work, it takes time for the formwork to be installed, the concrete being poured into the formwork, and then the concrete is cured.

이와 같은 콘크리트 양생 시간은 콘크리트 타설 면적이 커지면서 더욱 길어지게 되며, 특히 거푸집의 순차적 이동에 따라 콘크리트가 타설되는 터널공사에서는 콘크리트 양생 시간은 공사기간과 공사비용에 상당한 비중을 차지하게 된다.       Such concrete curing time becomes longer as the concrete pouring area becomes larger, and in particular, in the tunnel construction in which concrete is poured according to the sequential movement of the formwork, the concrete curing time takes a considerable part of the construction period and the construction cost.

이러한 문제점을 해결하기 위한 방편으로는 터널 내부에 열풍기, 히터, 등의 가열수단을 이용하여 양생을 돕게 되지만, 열 효율적으로 에너지의 손실이 많게 되어 비경제적이다.       As a way to solve this problem is to help the curing by using a heating means, such as a hot air fan, a heater, inside the tunnel, it is uneconomical to lose a lot of energy efficiently.

또한 전열선을 이용한 양생 방법으로는 콘크리트 타설시에 금속재의 거푸집 외표면에 길이를 따라 길게 전열선을 부착시키고 상기 전열선이 고정될 수 있도록 우레탄을 발포하여 고정시킨 다음, 전열선에 전원을 인가하여 금속 거푸집을 가열하게 됨에 따라 에너지의 손실이 거의 없이 신속하게 양생된다.      In addition, in the curing method using a heating wire, a heating wire is attached to the outer surface of the metal formwork along the length of the concrete during casting, and the urethane is foamed and fixed so that the heating wire can be fixed, and then the power is applied to the heating wire. As it heats up, it cures quickly with little loss of energy.

그러나 위와 같은 양생 방법은 콘크리트 양생이 완료된 이후 설치된 전열선을 거푸집으로부터 해체시키기 위해서 우레탄 등의 고정수단을 제거하기가 상당히 어렵고, 해체된 전열선은 파손되어 재활용되지 못하고 버려지게 된다.      However, the curing method as described above is difficult to remove the fixing means such as urethane in order to dismantle the heating wire installed after the concrete curing is completed, the dismantled heating wire is broken and can not be recycled.

본 발명은 거푸집의 순차적 이동에 따라 콘크리트가 타설되는 터널공사에서 콘크리트 양생 시간을 신속하게 하여 공사기간과 공사비용에 크게 줄일 수 있는 터널공사의 콘크리트 양생을 위한 가열장치를 제공함에 있다.The present invention is to provide a heating device for the concrete curing of the tunnel construction that can significantly reduce the construction period and construction costs by speeding up the concrete curing time in the tunnel construction in which concrete is poured in accordance with the sequential movement of the formwork.

또한, 본 발명의 다른 목적은 간단하고 신속하게 설치할 수 있으며 열에너지의 손실이 거의 없이 양생 공정을 수행한 다음, 간편하게 해체되어 재활용이 가능한 터널 공사의 콘크리트 양생을 위한 가열장치를 제공함에 있다. In addition, another object of the present invention is to provide a heating device for concrete curing of the tunnel construction that can be easily and quickly installed and performs a curing process with little loss of thermal energy, and then easily dismantled and recycled.

In particular, the recycled heating plate is economically effective to reduce industrial waste and also significantly reduce construction costs.

이하 본 발명의 바람직한 실시예를 하기에서 구체적으로 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail.

본 발명에서는 거푸집의 외측 표면으로 쉽게 탈/부착되는 가열판을 이용하여 콘크리트 타설 이후 신속하게 양생될 수 있는 터널공사의 콘크리트 양생을 위한 가열장치를 구현하고자 한다.The present invention is to implement a heating device for concrete curing of the tunnel construction that can be quickly cured after the concrete using a heating plate easily detachable / attached to the outer surface of the formwork.

먼저, 전기를 이용한 가열판(10)은 터널(40)의 길이방향을 따라 길게 연속적으로 배치되는 것이 바람직하며, 일측면은 콘크리트 벽체(20)를 형성하기 위한 거푸집(24)의 내측면에 밀착될 수 있도록 거푸집 표면의 굴곡부와 직선부에 따라 동일하게 형성되는 부착면(10a)을 가진다.First, the heating plate 10 using the electricity is preferably arranged in a long continuous direction along the longitudinal direction of the tunnel 40, one side is to be in close contact with the inner surface of the formwork 24 for forming the concrete wall (20) It has an attachment surface (10a) formed equally along the curved portion and the straight portion of the formwork surface.

그리고 상기 가열판(10)의 내부에는 열선(12)이 일정한 간격이 되도록 지그재그 형태로 배치되어 있고 일측 끝에는 외측으로 노출되는 플러그(14)를 가진다.In addition, the heating plate 10 has a plug 14 disposed in a zigzag form such that the heating wires 12 are spaced at regular intervals and exposed to the outside at one end thereof.

이와 같이 구성되는 가열판(10)은 보온 능력을 가지는 각종 수지에 의해서 성형되는 것이 바람직하며, 금형 바닥으로 열선(12)을 배치시키고 우레탄을 발포 성형하게 됨에 따라 간편하고 대량생산이 가능하게 된다.It is preferable that the heating plate 10 configured as described above is molded by various resins having heat insulating ability, and the heating wire 12 is placed on the bottom of the mold and the urethane foam is molded to enable simple and mass production.

한편, 거푸집(24)의 외측 표면으로는 전술한 가열판(10)을 고정시키기 위한 수단을 가진다.On the other hand, the outer surface of the formwork 24 has means for fixing the above-described heating plate 10.

즉, 상기 가열판은 일정한 폭으로 형성되며 소정을 길이를 가지면서 터널의 길이방향을 따라 길게 연속적으로 설치되는 것으로 거푸집의 외측 표면에는 상기 가열판이 밀착되도록 고정수단이 필요하다.In other words, the heating plate is formed in a constant width and has a predetermined length is installed continuously in the longitudinal direction of the tunnel, the fixing means is required so that the heating plate is in close contact with the outer surface of the formwork.

상기 고정수단으로는 가열판에 플랜지를 두고 나사 등으로 체결시킬 수 있고, 거푸집에 필수적으로 구비되어 있는 프레임(22)을 이용하게 됨에 별도의 장치를 구비하지 않고도 쉽게 고정시킬 수 있게 된다.The fixing means may be fastened with a screw or the like with a flange on the heating plate, and since the frame 22 is essentially provided in the formwork, it may be easily fixed without a separate device.

도 2에서와 같이 거푸집(24)의 외측 표면에는 터널(40)의 길이방향을 따라서 거푸집들을 고정시킬 수 있는 통상의 프레임(22)이 일정한 간격을 두고 설치되어 있고, 상부와 하부의 프레임 사이에 전술한 가열판(10)을 끼워 고정시킨다.On the outer surface of the formwork 24 as shown in Figure 2 is a conventional frame 22 which can be fixed to the formwork along the longitudinal direction of the tunnel 40 is provided at regular intervals, between the upper and lower frames The heating plate 10 described above is sandwiched and fixed.

이때 프레임의 근접부분으로 가열판에 회동하는 고정핀(16)을 설치한 다음, 상기 고정핀을 프레임 상면으로 회동시키면 가열판을 프레임에 더욱 견고하게 고정시킬 수 있을 것이다.At this time, by installing the fixing pin 16 that rotates to the heating plate in the vicinity of the frame, and then rotating the fixing pin to the upper surface of the frame will be able to more firmly fix the heating plate to the frame.

그리고, 상기 프레임(22) 내부를 따라서 전원공급선(32)을 투입시키고 가열판(10)에 있는 플러그(14) 지점에서 콘센트(30)를 연결시킨다. 따라서 각 플러그(14)를 콘센트(30)에 접속시켜 가열판(10)에 전원을 공급시킨다. Then, the power supply line 32 is inserted along the inside of the frame 22 and the outlet 30 is connected at the point of the plug 14 on the heating plate 10. Therefore, each plug 14 is connected to the outlet 30 to supply power to the heating plate 10.

이와 같이 구성되는 본 발명은 다음과 같이 사용된다.The present invention configured as described above is used as follows.

먼저, 거푸집을 설치하여 콘크리트를 타설시킨 이후 거푸집을 구성하고 있는 프레임(22)의 길이방향을 따라서 보온재에 의해서 성형된 가열판(10)들을 연속적으 로 그리고 상/하부면을 따라 거푸집 전체적으로 부착시킨다. 이후 각 플러그(14)들을 컨센트에 접속시키고 전원을 연결시키게 됨에 따라 열선(12)이 가열되면서 프레임이 고온으로 상승하게 된다. 동시에 터널 콘크리트 벽체(20)가 가열되면서 양생되기 시작하며 양생이 완료된 후 플러그(14)를 뽑고 가열판(10)을 탈리시킨 다음, 다음 콘크리트 타설을 위한 위치로 이동하여 양생공정을 수행하게 된다. First, after installing the formwork to pour the concrete, along the longitudinal direction of the frame 22 constituting the form the heating plate (10) formed by the heat insulating material continuously and attached to the entire form along the upper / lower surface. Then, as each plug 14 is connected to a power outlet and a power source is connected, the heating wire 12 is heated to raise the frame to a high temperature. At the same time, the tunnel concrete wall 20 starts to be cured as it is heated, and after curing is completed, the plug 14 is pulled out and the heating plate 10 is detached, and then the curing process is performed by moving to the position for the next concrete placing.
