Description
본 고안은 후막 파형 웨브를 구비한 철제 I-빔에 관한 것으로, 보다 구체적으로 일정한 두께 이상의 파형 웨브를 구비하여 중량 구조물에 적용되는 철제 I-빔에 관한 것이다.The present invention relates to an iron I-beam having a thick-film corrugated web, and more particularly to an iron I-beam having a corrugated web of a predetermined thickness or more and applied to a heavy structure.
철제 I-빔은 단면계수가 크기 때문에 토목공사에 주로 사용된다.Steel I-beams are mainly used in civil engineering because of their large cross-sectional coefficients.
그러나, 철제 I-빔은 수직 방향으로의 강성에 대해 약하기 때문에 파형 웨브(web)를 적용한 철제 I-빔이 사용되고 있다.However, iron I-beams are weak against stiffness in the vertical direction, and therefore, iron I-beams with a corrugated web are used.
도 1은 종래의 철제 I-빔을 보여주는 사시도이다.1 is a perspective view showing a conventional iron I-beam.
도시된 바와 같이, 상부 플랜지(20)와 하부 플랜지(10)가 서로 대향한 상태에서 그 사이에 단면이 파형을 이루는 강재 웨브(30)가 끼워져 상단과 하단이 각각 상부 플랜지(20)와 하부 플랜지(10)에 용접된다.As shown, the upper and lower flanges of the upper and lower flanges, respectively, with the upper and lower flanges of the upper and lower flanges 10, the web 30 is inserted into the steel web 30 having a cross-sectional waveform between them Weld on 10.
강재 웨브(30)의 단면 파형은 사인파(sine wave) 곡선과 같이 라운드 형상으로 통상 2 내지 5mm 정도의 두께를 갖는다.The cross-sectional waveform of the steel web 30 has a thickness of about 2 to 5 mm in a round shape like a sine wave curve.
이러한 단면 파형을 형성하기 위해서는 강재 원판을 롤 포밍(roll forming)을 적용한다. To form such a cross-sectional waveform, roll forming is applied to the steel disc.
상기한 철제 I-빔은 어느 정도의 압력에는 충분히 대응할 수 있으나, 중량 구조물에 대해서는 수직방향으로의 강성이 충분하지 않다는 문제가 있다.The iron I-beam described above can cope with a certain pressure sufficiently, but there is a problem that the rigidity in the vertical direction is not sufficient for the heavy structure.
이러한 문제를 해결하기 위하여 강재 웨브의 두께를 증가시키는 방법을 고려할 수도 있지만, 상기한 롤 포밍에 의한 가공 두께에는 한계가 있다.In order to solve this problem, a method of increasing the thickness of the steel web may be considered, but there is a limit in the processing thickness by the roll forming described above.
따라서, 본 고안의 목적은 중량 구조물에 대해 충분한 강성을 가지며, 제조가 용이한 철제 I-빔을 제공하는 것이다.Accordingly, it is an object of the present invention to provide an iron I-beam that has sufficient rigidity for heavy structures and is easy to manufacture.
본 고안의 다른 목적과 특징 및 이점은 이하에 서술되는 실시예로부터 명확하게 이해될 것이다.Other objects, features and advantages of the present invention will become apparent from the examples set forth below.
본 고안에 따르면, 상부 플랜지와 하부 플랜지가 대향하여 이격된 공간에 강재 웨브가 삽입되어 그 상단과 하단이 각각 상기 상부 플랜지와 하부 플랜지에 고정된 철제 I-빔에 있어서, 강재 웨브는 그 단면이 골과 언덕이 교대로 반복되는 파형을 이루고, 하나의 골이나 언덕을 이루는 단위 파형은 사다리꼴을 이루며, 강재 웨브의 두께는 10mm 이상이고, 단위 파형의 길이와 폭은 대략 동일한 철제 I-빔이 개시된다.According to the present invention, in a steel I-beam in which a steel web is inserted into a space spaced apart from an upper flange and a lower flange so that the upper and lower ends thereof are respectively fixed to the upper flange and the lower flange, the steel web has a cross section thereof. The valley and the hill form an alternating wave form, the unit wave form one valley or hill form a trapezoid, the steel web is more than 10mm thick, and the iron wave I-beam of about the same length and width of the unit wave is started. do.
이하, 첨부된 도면을 참조하여 본 고안의 실시예를 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.
도 2는 본 고안의 일 실시예에 따른 철제 I-빔을 보여주는 사시도이다.2 is a perspective view showing an iron I-beam according to an embodiment of the present invention.
도시된 바와 같이, 상부 플랜지(200)와 하부 플랜지(100)가 서로 대향한 상태에서 그 사이에 단면이 파형을 이루는 강재 웨브(300)가 끼워져 상단과 하단이 각각 상부 플랜지(200)와 하부 플랜지(100)에 용접된다.As shown in the figure, the steel web 300 having a corrugated cross section is inserted in the state where the upper flange 200 and the lower flange 100 face each other so that the upper flange and the lower flange are the upper flange 200 and the lower flange, respectively. Welded to 100.
강재 웨브(300)는 그 단면이 골(또는, 언덕)(320)과 언덕(또는, 골)(310)이 교대로 반복되는 파형을 이루며, 단위 파형은 사다리꼴을 이룬다.The steel web 300 has a cross section whose waveform is alternately repeated with the valley (or hill) 320 and the hill (or valley) 310, and the unit waveform is trapezoidal.
강재 웨브(300)의 두께 t는 10mm 이상이며, 바람직하게 하나의 골(320)이나 언덕(310)을 이루는 단위 파형의 길이 L과 단위 파형의 폭 W는 대략 동일하다. 이와 같이, 단위 파형의 길이 L과 단위 파형의 폭 W을 대략 동일하게 구성함으로써 상하방향으로 인가되는 외력에 구부러지는 것을 확실하게 방지할 수 있다.The thickness t of the steel web 300 is 10 mm or more, and preferably, the length L of the unit waveform forming the valley 320 or the hill 310 and the width W of the unit waveform are approximately the same. In this way, by configuring the length L of the unit waveform and the width W of the unit waveform substantially the same, it is possible to reliably prevent the bending of the external force applied in the vertical direction.
상기한 바와 같이, 강재 웨브(300)는 10mm 이상의 두께를 갖기 때문에 상기한 롤 포밍으로는 제작이 곤란하며, 프레스 가공을 이용하여 제작할 수 있다.As described above, since the steel web 300 has a thickness of 10 mm or more, it is difficult to manufacture by the above-mentioned roll forming, and can be manufactured by using press working.
이와 같은 구조에 의하면, 강재 웨브의 두께를 크게 증가시킬 수 있기 때문에 수직방향(즉, 상하방향)으로 외부에서 인가되는 힘에 대해 큰 강성을 가지며, 구부러짐에 대해서도 강하게 된다.According to such a structure, since the thickness of a steel web can be greatly increased, it has big rigidity with respect to the force applied externally in a vertical direction (namely, up-down direction), and becomes strong also against bending.
또한, 프레스 가공에 의해 파형을 형성할 수 있어 제작이 용이하다는 이점이 있다.In addition, the waveform can be formed by press working, there is an advantage that the production is easy.
이상에서는 본 고안의 바람직한 실시예를 중심으로 설명하였지만, 본 고안의 범주를 벗어나지 않고 당업자의 기술 수준에서 다양한 변경과 변형을 가할 수 있으며, 이러한 변경과 변형은 당연히 본 고안의 범위에 속한다고 할 것이다.In the above described with reference to a preferred embodiment of the present invention, various changes and modifications can be made in the technical level of those skilled in the art without departing from the scope of the present invention, these changes and modifications will naturally be within the scope of the present invention. .
이상에서 설명한 바와 같이, 본 고안에 따르면 중량 구조물에 대해 충분한 강성을 가지며, 제조가 용이하다는 이점이 있다.As described above, according to the present invention, there is an advantage of having sufficient rigidity with respect to the weight structure, and easy to manufacture.

도 2는 본 고안의 일 실시예에 따른 철제 I-빔을 보여주는 사시도이다.2 is a perspective view showing an iron I-beam according to an embodiment of the present invention.
