Description

금속부재간 용접 연결구조{welded connection structure between metal members}Welded connection structure between metal members

본 발명은 두 개의 금속부재를 결합하기 위한 기술로서, 구체적으로는 소정의 결합각도를 이루는 두 금속부재를 용접으로 결합할 때 용접 흔적을 최소화할 수 있으면서 결합력도 향상시킬 수 있도록 하는 금속부재간 용접 연결구조에 관한 것이다.The present invention is a technique for joining two metal members, and specifically, when two metal members forming a predetermined joining angle are joined by welding, welding marks between metal members can be minimized and the bonding strength can be improved. It is about the connection structure.

산업적으로 규격화된 금속부재들이 많이 사용되고 있으며, 이들 금속부재들을 소정길이 및 각도로 절단하여 서로 연결 결합함으로써 원하는 다양한 형상의 제품이나 구조물을 제작하게 된다.Industrially standardized metal members are widely used, and by cutting these metal members at a predetermined length and angle and connecting them to each other, products or structures of various desired shapes are manufactured.

대표적인 규격화된 금속부재로는 앵글, 찬넬, 빔 등이 있는데, 이러한 금속부재를 활용하여 제작되는 일 예로는 케이블트레이와 같은 제품이 있다.Typical standardized metal members include angles, channels, beams, and the like, and an example of manufacturing using these metal members is a product such as a cable tray.

케이블트레이는 건축물 시공시 필수적으로 사용되는 것으로서 전선과 같은 많은 케이블을 안전하게 건축물 내부에 설치하기 위한 것이다.The cable tray is essential for building construction and is intended to safely install many cables such as electric wires inside the building.

케이블트레이는 전기가 흐르는 다수의 전선들을 지지하는 요소이므로 접지가 잘되어야 하고 고하중에도 견딜 수 있는 내구성도 요구된다.Since the cable tray is an element that supports a large number of electric wires, it must be well grounded and durable to withstand high loads is also required.

통상적인 케이블트레이는 이격거리를 두고 마주보게 배치되는 한 쌍의 사이드레일과 두 사이드레일과 직교되게 배치되면서 각 단부에서 사이드레일과 결합되는 복수의 렁으로 이루어진다.A typical cable tray consists of a pair of side rails disposed to face each other at a distance and a plurality of rungs coupled to the side rails at each end while being disposed perpendicular to the two side rails.

사이드레일의 일측면에 렁의 각 단부를 맞대어 용접으로 결합하게 되는데, 렁의 단면은 대략 ㄷ 자 형상의 찬넬과 유사하다. 즉, 렁은 내부가 비어있는 형상이고 어느 일면은 개구되어 있다. 따라서 렁의 각 단부를 사이드레일의 일측면에 용접 결합하게 되면 렁의 가장자리를 따라 용접이 이루어질 수 밖에 없는데, 용접이 이루어지는 영역이 좁아 결합력이 약하다는 문제점이 있었다.Each end of the rung is buttted to one side of the side rail and joined by welding. The cross section of the rung is similar to that of a U-shaped channel. That is, the rung is hollow inside and one side is open. Therefore, when each end of the rung is welded to one side of the side rail, welding is inevitable along the edge of the rung, but there is a problem in that the welding area is narrow and the bonding force is weak.

이에 따라 기존의 용접방식을 제작되는 케이블트레이의 경우 쉽게 뒤틀리거나 사이드레일과 렁의 연결부위가 파손되는 경우가 많았다.Accordingly, in the case of cable trays manufactured using the conventional welding method, there were many cases where they were easily twisted or the connection part between the side rail and the rung was damaged.

이런 문제점을 보완하고자 볼팅을 이용한 연결구조가 제시되기도 했지만 볼팅의 경우 접지 성능이 떨어진다는 문제점이 있었다. To compensate for this problem, a connection structure using bolting has been proposed, but in the case of bolting, there is a problem that the grounding performance is poor.

케이블트레이와 같은 금속부재를 절단한 후 서로 연결하여 소정 형상의 제품이나 구조물을 제작하는 경우는 매우 흔하며, 두 부재간 결합을 위해 가장 일반적으로 활용되는 기술이 용접이라 할 수 있다.It is very common to cut a metal member such as a cable tray and connect it to each other to manufacture a product or structure of a predetermined shape, and welding is the most commonly used technique for bonding between two members.

용접은 장점과 단점이 있는데, 단점 중 하나는 용접 후 용접부위 주위가 지저분하게 변색된다는 것이다.Welding has advantages and disadvantages, but one of the disadvantages is that the area around the welded area is discolored messily after welding.

제2부재(200)인 렁은 내부가 비어있는 ㄷ 자 단면을 갖는 형상이며, 제2부재(200)의 일단부에 연결편(300)이 구속되게 삽입되게 한다. 연결편(300)은 제2부재(200)의 일단부에 끼워져 용접 등의 방식으로 고정 연결되게 하거나, 제2부재(200)의 단부에 걸림턱(210)을 형성시켜서 연결편(300)이 이탈되지 않도록 하여도 된다.The rung, which is the second member 200 , has a shape having an empty U-shaped cross-section, and allows the connecting piece 300 to be inserted into one end of the second member 200 to be constrained. The connecting piece 300 is inserted into one end of the second member 200 to be fixedly connected by welding, etc. may be avoided.

한편, 연결편(300)은 소정 두께를 갖는 사각 판상체와 같은 형상으로 하며, 연결편(300)의 중심부에는 하나 이상의 관통구(310)가 형성된다. 관통구(310)는 원형을 기본으로 하여 다양한 형상이 적용될 수 있다. 제1부재(100)의 접합면(110)에 제2부재(200)의 일단을 맞대게 되면 연결편(300)이 접합면(110)과 마주보는 상태가 되며, 연결편(300)의 관통구(310)를 통해 용접이 이루어지도록 함으로써 제1부재(100)와 제2부재(200)가 결합되도록 한다.On the other hand, the connecting piece 300 has the same shape as a rectangular plate-shaped body having a predetermined thickness, and at least one through hole 310 is formed in the center of the connecting piece 300 .

이어서 본 발명의 또 다른 실시예에 대해 설명하도록 한다.Next, another embodiment of the present invention will be described.

도 5는 본 발명의 또 다른 실시예에 대한 분해 사시도이며,5 is an exploded perspective view of another embodiment of the present invention,

도시된 것처럼 연결편(300)은 이면연결편(300a)이거나 3면연결편(300b)으로 이루어질 수 있음에 특징이 있다.As shown, the connecting piece 300 is characterized in that it may be formed of a back connecting piece (300a) or a three-sided connecting piece (300b).

ㄷ 자 단면 형상을 갖는 제2부재(200)의 각 단부 내부에 이면연결편(300a)이나 3면연결편(300b)을 끼워넣도록 하며, 최소 두개의 면을 이용하여 제1부재(100) 및 제2부재(200)와 연결되게 용접하도록 한다.The back connection piece 300a or the three-sided connection piece 300b is inserted into each end of the second member 200 having a C-shaped cross-sectional shape, and the first member 100 and the first member 100 using at least two surfaces It is to be welded to be connected to the second member (200).

도 5과 같이 이면연결편(300a)은 ㄱ 자 형상을 갖게 되며 제1면(301)과 제2면(302)을 갖추고 있다. 제1면(301)과 제2면(302) 각각에 관통구(310)가 형성되며 제2면(302)의 관통구를 통해 제2부재(200)의 상면과 용접 결합되게 하고, 제1면(301)의 관통구를 통해 제1부재(100)의 접합면(110)과 용접이 이루어지게 할 수 있다. 한편, 이면연결편(300a)의 배치방향에 따라 제2면(302)의 관통구는 제2부재(200)의 측면과 용접되게 할 수도 있다.As shown in FIG. 5 , the back connection piece 300a has a L-shape and has a first surface 301 and a second surface 302 . A through hole 310 is formed in each of the first surface 301 and the second surface 302 , and is welded to the upper surface of the second member 200 through the through hole of the second surface 302 , and the first Through the through hole of the surface 301 , welding may be performed with the bonding surface 110 of the first member 100 . On the other hand, the through hole of the second surface 302 may be welded to the side surface of the second member 200 depending on the arrangement direction of the back surface connection piece 300a.

그리고 연결편(300)으로 3면연결편(300b)이 사용되는 경우에는 제1면(301), 제2면(302), 제3면(303) 각각에 관통구(310)가 형성되게 하며, 제2부재(200)의 일단에 3면연결편(300b)을 끼워 넣은 후 최소 두개면에 형성된 관통구(310)를 통해 제1부재(100) 및 제2부재(200)와 용접 결합되게 한다.And when the three-sided connecting piece 300b is used as the connecting piece 300, a through hole 310 is formed in each of the first surface 301, the second surface 302, and the third surface 303, After inserting the three-sided connecting piece 300b into one end of the second member 200, the first member 100 and the second member 200 are welded together through the through-holes 310 formed in at least two surfaces.

즉, 제1면(301)은 제1부재(100)의 접합면(110)과 용접 결합되게 하고, 제2면(302)은 제2부재(200)의 상면과 용접되게 하고, 제3면(303)은 제2부재(200)의 일측면과 용접되게 할 수 있다.That is, the first surface 301 is welded to the bonding surface 110 of the first member 100 , and the second surface 302 is welded to the upper surface of the second member 200 , and the third surface Reference numeral 303 may be welded to one side of the second member 200 .

본 발명의 경우 연결편(300)의 중심에 형성되는 관통구(310)에서 용접이 이루어지도록 함으로써 용접시의 고온의 열에 의한 주변의 열화로 인한 변색을 최소화할 수 있게 된다. 즉, 연결편(300)의 관통구(310) 주변으로만 용접시 고열로 인한 변색이 발생되므로 외관상으로도 보다 깔끔하며 결합 강도도 향상시킬 수 있다는 장점이 있다.In the present invention, by allowing welding to be performed in the through hole 310 formed in the center of the connecting piece 300 , discoloration due to deterioration of the surroundings due to the high temperature heat during welding can be minimized. That is, when welding only around the through hole 310 of the connecting piece 300 , discoloration due to high heat is generated, so it is cleaner in appearance and the bonding strength can be improved.

더 나아가 본 발명의 금속부재간 용접 연결구조에는 연결편(300)의 관통구(310)를 통해 이루어지는 용접부가 노출되지 않도록 용접 완료 후 덮개판(400)으로 연결편(300)을 덮어 용접부가 보이지 않도록 한다.Furthermore, in the welding connection structure between metal members of the present invention, after welding is completed, the welding portion formed through the through hole 310 of the connecting piece 300 is not exposed by covering the connecting piece 300 with the cover plate 400 so that the welding portion is not visible. .

한편, 제2부재(200)에 결합된 연결편(300)의 관통구(310)를 통한 제1부재(100)의 접합면(110)과의 용접은 레이저 용접으로 실시토록 하는 것이 바람직하나 그 외 공지의 용접으로 하여도 무방하다.On the other hand, welding with the joint surface 110 of the first member 100 through the through hole 310 of the connection piece 300 coupled to the second member 200 is preferably performed by laser welding, but other Well-known welding is also possible.

그리고 본 실시예에서는 제1부재로 사이드레일로 하고 제2부재는 렁인 것으로 하여 케이블트레이이를 구성하는 것을 보여주었지만, 제1부재와 제2부재는 그 외의 명칭으로 불리울 수 있는 금속성 부재일 수 있다.And in this embodiment, the first member is a side rail and the second member is a rung to form a cable tray, but the first member and the second member may be metallic members that can be called by other names. there is.

단, 제2부재는 내부가 비어있는 부재로서 찬넬과 같은 것이며, 그 단면 형상은 ㄷ 자 외에 다양할 수 있고, 제2부재의 단면 형상에 맞게 연결편의 형상도 달라질 수 있는 것이다.However, the second member is a member with an empty interior, such as a channel, and its cross-sectional shape may vary other than the C-shape, and the shape of the connecting piece may also be changed to match the cross-sectional shape of the second member.

본 발명은 용접으로 금속부재들을 연결 결합하고자 할 때 유용하게 활용될 수 있는 기술이다.The present invention is a technique that can be usefully utilized when connecting and combining metal members by welding.
