또한, 공개특허공보 공개번호 10-2016-0073863호에는 장방형 형상의 수평면을 형성하는 상단부와, 상기 상단부 길이방향의 양끝단에서 하방으로 절곡되어 형성되며, 끝단이 서로 맞닿도록 형성되는 측면부와, 상기 측면부 하측 양끝단에 마련되며, 상기 측면부의 길이방향으로 돌출되어 형성되는 돌출부를 포함하여 구성되는 것을 특징으로 하는 그레이팅 결속클립이 공개되어 있다.In addition, in Laid-Open Patent Publication No. 10-2016-0073863, an upper end forming a horizontal plane of a rectangular shape, a side portion formed by bending downward at both ends in the longitudinal direction of the upper end, and a side portion formed so that the ends abut each other, and the A grating binding clip is disclosed, which is provided at both ends of the lower side of the side part, and comprises a protrusion formed to protrude in the longitudinal direction of the side part.
그러나 기존 형태의 고정 클립의 경우 그레이팅을 상부의 새들클립과 하부의 하부클립을 단순히 볼트 너트를 각각 사용하여 결합하여 제약된 공간에 따라 설치에 어려움이 있었다.However, in the case of the existing type of fixing clip, it was difficult to install the grating according to the limited space by simply combining the upper saddle clip and the lower lower clip using bolt nuts.
그러므로 종래기술들은 중량이 나가는 그레이팅의 경우 손으로 옮기는데 제한사항이 있고, 볼트의 사용에 있어서는 볼트의 길이가 그레이팅 상단을 넘어서게 되면 이동간에 안전사고등의 발생우려가 있으며 짧으면 설치에 어려움이 발생하였다. 또한 앵글 등 하부에 설치되는 앵글이나 H-Beam의 경우 다양한 두께의 사용으로 인한 사용 볼트 길이가 상이함에 따른 어려움이 있었다.Therefore, in the prior art, there is a limitation in moving the grating by hand in the case of a heavy grating, and when the length of the bolt exceeds the top of the grating in the use of the bolt, there is a risk of safety accidents during movement, and if it is short, there is a difficulty in installation. Also, in the case of angles or H-beams installed in the lower part, such as angles, there was a difficulty due to the use of different bolt lengths due to the use of various thicknesses.
또한, 기존 Bolt와 Nut는 자주 풀림 현상이 발생하여 재설치 하는 문제가 발생하는 단점이 있었다.In addition, the existing bolts and nuts frequently loosened and had a problem of reinstallation.
그레이팅의 Bearing Bar의 간격은 20mm~45mm의 간격으로 제작되며 사람이나 차량의 이동을 고려한다면 안전을 위해 좁은 간격이 유리하다. 따라서 통상적으로 사용되는 그레이팅의 간격은 25mm로 협소한 공간이 발생하고 이 협소한 공간에 상부에 Saddle Clip을 하부에 Lower Clip을 위치하여 그레이팅과 그레이팅을 지지해주는 구조물을 볼트-너트를 사용하여 상-하로 작용하는 힘을 이용하여 고정한다.The spacing between the bearing bars of the grating is 20mm to 45mm, and if the movement of people or vehicles is considered, a narrow spacing is advantageous for safety. Therefore, the spacing of gratings normally used is 25mm, which creates a narrow space, and in this narrow space, the saddle clip is placed on the upper part and the lower clip is located on the lower part. It is fixed using a downward force.
이때 클립의 파손 방지와 안정된 고정력을 얻기 위해서는 그레이팅 하단부 양쪽 bearing bar와 구조물을 받쳐주는 형태가 가장 안정적인데 해당 방식으로 고정하기 위해서는 그레이팅 Bearing Bar를 받쳐주는 Lower Clip의 날개부가 그레이팅 간격보다 넓어 상부에서 그레이팅 간격사이로 밀어 넣어 설치하기에는 어려움이 있어 상하부에 각각 인원이 배치되어 설치하는데 고소작업간에는 하부 설치 인원은 하네스에 의존하여 공중에 매달려 설치하는 등 매우 위험에 따라 개선이 필요하다.At this time, in order to prevent clip breakage and obtain stable fixing force, the most stable form of supporting the structure and both bearing bars of the lower part of the grating is to fix it in this way. It is difficult to install it by pushing it between the gaps, so it is installed by placing personnel on the upper and lower parts.
또한 볼트를 조일시 너트를 잡아줘야 하는데 상부에서 볼트를 조일시 좁은 그레이팅 간격에 손을 넣거나 3번항에서 언급한것과 같이 공중에 매달려 너트를 잡아줘야 하는 문제점이 발생한다. 이때 실수에 의해 너트의 낙하와 하부 클립(Lower Clip)의 낙하로 인해 특히 고소작업간에 안전사고의 우려가 높다.Also, when tightening the bolt, you have to hold the nut, but when you tighten the bolt from the top, you have to put your hand into the narrow grating gap or hang the nut in the air as mentioned in item 3, there is a problem. At this time, there is a high risk of safety accidents, especially during work at height, due to the fall of the nut and the fall of the lower clip by mistake.
기존에 이를 개선한 제품이 있으나 그레이팅 Bearing Bar 한쪽면과 구조물의 연결을 통해 수평으로 작용하는 힘에 있어 쉽게 이탈하여 고정력을 상실하는 문제가 있으며 구조물에 홀을 가공하여 타정총을 활용하거나 스크류를 이용한 방식은 수평으로 작용하는 힘에 있어 쉽게 부러지거나 가공한 홀에서 발생하는 녹으로 인한 문제, 홀 가공시 쇳가루의 비산으로 해당 쇳가루에 의한 녹발생 및 주요장비 기능고장이 원인이 되는 문제와 더불어 설치 과정이 복잡한 공정을 거쳐야 하는 문제점이 있다.There are products that have improved this in the past, but there is a problem in that the force acting horizontally through the connection of one side of the grating bearing bar and the structure is easily separated and loses the fixing power. In terms of the horizontal force, the problem is caused by easily broken or rust generated in the machined hole, and the problem of rust generation and malfunction of major equipment due to the scattering of iron powder during hole processing. There is a problem in having to go through this complicated process.
또 다른 문제점으로는 설치간 다양한 조건과 환경에 따른 문제점이 있는데 그레이팅을 받치고 있는 구조물의 두께에 따라 bearing Bar 하단부까지의 높이가 달라지게되고 구조물의 두께가 높아질수록 기존 사용하는 클립의 고정력이 떨어짐에 따라 다양한 종류의 클립이 존재해야 된다는 문제점이 있다. 이때 다양한 형태의 클립을 제작하기 위한 금형을 제작해야 되고 이에 따른 비용의 증가가 예상된다.Another problem is that there are problems depending on various conditions and environments during installation. The height to the lower end of the bearing bar varies depending on the thickness of the structure supporting the grating, and as the thickness of the structure increases, the fixing force of the existing clip decreases. Accordingly, there is a problem that various types of clips must exist. At this time, it is necessary to manufacture a mold for producing various types of clips, and the cost is expected to increase accordingly.
또한 그레이팅은 Bearing Bar와 Cross Bar가 격자무늬 형태로 용접된 형태로 되어 있는데 그레이팅은 비규격제품으로 설치간 구조물과 Cross Bar의 간격이 어중간하여 클립의 설치를 어렵게 하는 부분이 있다.In addition, the grating is a form in which the bearing bar and the cross bar are welded in the form of a grid pattern. The grating is a non-standard product, and there is a part that makes the installation of the clip difficult because the distance between the structure and the cross bar between installations is ambiguous.
마지막으로 설치 현장에서 상부클립, 하부클립, 볼트, 너트를 결합해야 하는데 추가 공정의 발생 및 분실에 따른 공정지연의 문제가 있다.Finally, the upper clip, lower clip, bolt, and nut must be combined at the installation site, but there is a problem of process delay due to the occurrence or loss of additional processes.
본발명은 상기와 같은 문제점을 해결하고자 안출된 것으로, 클립 하부클립에 태핑이된 플랜지 구멍(돌기부)을 형성하며 돌기를 형성하여 너트 등이 필요없으므로 제한된 공간에서 사용 가능하여 보다 손쉽게 그레이팅 설치가 가능하며, 직사각형단면의 하변 중앙이 개방된 채널형상으로 길이가 긴 수평부가 설치되어 그레이팅 하부에 설치하는 Angle, H-beam의 다양한 규격에 설치가 가능하도록 표준화할 수 있으며 볼트가 그레이팅 상단부 위로 튀어나오는 부분이 없어 안전한 그레이팅 고정용 클립 제작방법을 제공하고자 하는 것이다.The present invention has been devised to solve the above problems, and the flange hole (protrusion) tapped in the clip lower clip is formed, and the protrusion is formed to eliminate the need for a nut, etc. The rectangular cross section has a channel shape with an open lower center, and a long horizontal part is installed so that it can be standardized for installation in various standards of angle and H-beam installed under the grating, and the part where the bolt protrudes above the upper part of the grating It is intended to provide a method for manufacturing a clip for fixing the grating that is safe because there is no such thing.
또한, 상기 문제점을 해결하기 위해서는 구조물을 훼손하지 않으며 Saddle Clip, Lower Clip, 볼트, 너트가 사전에 결합된 형태에서도 그레이팅 상부에서 밀어 넣을 수 있는 클립의 개발이 필요하다.In addition, in order to solve the above problem, it is necessary to develop a clip that does not damage the structure and can be pushed in from the top of the grating even in the form in which the saddle clip, lower clip, bolt, and nut are previously combined.
이에 따라 하단(Lower Clip)의 날개부가 회전 및 원위치가 가능하도록 스프링을 활용하여 좌우 또는 상하로 90°움직일 수 있도록 제작하여 그레이팅 Bearing Bar 사이를 손쉽게 통과할 수 있도록 하였으며 통과 후 양쪽 베어링바와 구조물을 고정하여 안정적인 고정력 및 클립의 파손을 방지한다.Accordingly, the wing of the lower clip is made to move 90° left and right or up and down using a spring so that it can rotate and return to its original position so that it can easily pass between the grating bearing bars. After passing, both bearing bars and structures are fixed This prevents stable fixing and clip breakage.
또한 브라켓의 교체가 가능하도록 하여 구조물의 두께에 따라서도 대응이 가능하도록 한다.In addition, it is possible to replace the bracket so that it can respond according to the thickness of the structure.
