본 고안은 콘크리트 거푸집 체결용 윙너트에 관한 것으로 보다 구체적인 것은, 일정규격으로 만든 금속제 육각너트와, 일정두께의 금속판을 직사각형으로 절단하여 중간부에 육각너트결합부를 형성하여 결합구멍을 뚫고, 결합의 양측을 40°각으로 상향시켜 손잡이부를 형성한 윙판체와, 윙판체에 육각너트를 결합하여 윙너트를 형성함으로써, 육각너트와 윙판체가 일체가 되어 내구성이 확보되고, 생산성을 높여 경쟁력 있는 제품을 공급할 수 있게 한 것이다.The present invention relates to a wing nut for fastening a concrete formwork, and more specifically, a metal hexagon nut made of a certain standard and a metal plate of a certain thickness are cut into a rectangle to form a hexagon nut coupling part in the middle part, drill a coupling hole, and The wing plate body is formed by raising both sides at an angle of 40°, and the hexagon nut is combined with the wing plate body to form a wing nut. that made it possible to supply
종래의 거푸집 체결용 윙너트는 너트 양측에 윙날개가 돌출되게 일체로 주조하여 나사구멍을 형성하거나, 금속소재를 단조성형하여 너트와 날개를 형성하는 방법으로 윙너트를 제조하기 때문에 너트부와 윙날개 부분이 일체로 형성되지만, 주조제품은 생산이 복잡하고, 재질의 특정으로 취성이 강해 저항을 받을 때, 쉽게 부러지는 불편이 있고, 단조제품은 너트와 윙날개가 일체로 성형되기 때문에 연결부가 두텁게 형성되어 중량이 커지는 불편이 있고, 중량을 줄이면 너트와 윙날개연결부가 약해져서 쉽게 변형되는 불편이 있었다.The conventional wing nut for fastening the formwork is integrally cast so that the wing wings protrude on both sides of the nut to form a screw hole, or a metal material is forged to form a nut and a wing nut. Although the wing part is integrally formed, the casting product is complicated to produce, and due to the specific material of the material, it is brittle and has the inconvenience of being easily broken when subjected to resistance. It is formed thickly and has the inconvenience of increasing the weight, and when the weight is reduced, the nut and the wing wing connection part become weak and are easily deformed.
본 고안은 상기 불편을 해소하기 위하여 개발한 것이다.The present invention was developed to solve the above inconvenience.
본 고안은 금속제로 되어 정육각형을 이루고 중심에 나사구멍이 형성되며, 하단부에 결합부가 있는 육각너트와, 금속판재를 선택하여 가로세로 길이가 일정규격을 가지는 직4각형판을 만들어 판체중심부에 육각너트결합부를 형성하여 중심부에 육각너트에 형성된 결합부 형상과 같은 육각형결합구멍을 형성하고, 육각너트결합부 양측을 40°각으로 경사지게 형성하여 손잡이부를 형성한 윙판체로 이루어져 육각너트 하단결합부를 윙판체의 육각형결합구멍에 강제 결합하여, 육각너트와 윙판체가 일체를 이루게 한 것이다.The present invention is made of metal to form a regular hexagon, a screw hole is formed in the center, and a hexagon nut having a coupling part at the lower end, and a metal plate material are selected to make a rectangular plate having a certain standard in width and length, and a hexagon nut in the center of the plate body It consists of a wing plate body in which a handle part is formed by forming a coupling part, forming a hexagonal coupling hole like the coupling part shape formed in the hexagonal nut in the center, and forming the hexagon nut coupling part to be inclined at a 40° angle, and the hexagon nut lower coupling part of the wing plate body The hexagonal nut and the wing plate body are formed into one body by forcibly joining the hexagonal coupling hole.
상기에서 육각너트에 형성되는 결합부는 육각너트 하단 나사구멍 외주에 육각너트 외경보다 작은 규격의 육각형돌출부가 일정높이로 돌출되게 하여 윙판체의 육각형 결합구멍에 결합하고, 육각너트 외주와 윙판체사이를 용접제로 용접하거나, 육각너트하단부에 육각너트 외경보다 크게 외주로 확장되어 윙판체의 육각형 결합구멍 저면외주에 접촉하는 하단접촉판과, 하단접촉판 상면과 육각너트하단부 사이에서 육각형상으로 형성되고, 높이가 윙판체 두께 보다 더 높고 외경이 육각너트외경보다는 크고 하단접촉판 보다는 작은 육각형결합부가 형성되어 육각형결합부를 윙판체의 육각형결합구멍에 끼워 상단부가 윙판체 상면으로 돌출되면 압착도구로 윙판체 상면으로 돌출된 육각형결합부 상단외주를 윙판체상면으로 가압하여 가압된 육각형결합부 외주가 윙판체의 육각형결합구멍 상단부 외주에 밀착되어 육각너트와 윙판체가 강제 결합되게 하는 구성이다.The coupling portion formed in the hexagon nut in the above is coupled to the hexagonal coupling hole of the wing plate body by making a hexagonal protrusion smaller than the hexagon nut outer diameter protrude to a certain height on the outer periphery of the hexagonal nut lower screw hole, and between the hexagonal nut outer periphery and the wing plate body It is welded with a welding agent or formed in a hexagonal shape between the lower contact plate and the upper surface of the lower contact plate and the lower end of the hexagon nut, and the lower contact plate extends to the outer periphery larger than the outer diameter of the hexagon nut at the lower end of the hexagon nut and contacts the outer periphery of the bottom surface of the hexagonal coupling hole of the wing plate body, The height is higher than the thickness of the wing plate and the outer diameter is larger than the outer diameter of the hexagonal nut and smaller than the lower contact plate is formed. By pressing the upper periphery of the hexagonal coupling part protruding to the upper surface of the wing plate body, the pressed hexagonal coupling part outer periphery is in close contact with the upper periphery of the hexagonal coupling hole of the wing plate body, so that the hexagonal nut and the wing plate body are forcibly coupled.
이와 같이 된 본 고안은 육각너트와 윙판체를 별도로 만들어서 윙판체의 육각형결합구멍에 육각너트의 결합부에 형성된 육각형돌출부를 강제 결합시켜 일체화시키기 때문에 육각너트와 윙판체가 이완됨이 없이 결합되어 일체가 되고, 육각너트와 윙판체의 규격을 다양하게 선택할 수 있는 이점이 있고, 육각너트와 윙판체를 별도로 만들어 결합시키기 때문에 제작능률을 높일 수 있어 생산성이 향상되고, 불량품의 발생이 적고, 규격이 다양한 제품을 양산할 수 있어서 경쟁력 있는 제품생산을 달성할 수 있으며, 내구성이 양호한 제품을 만들어 공급할 수 있는 이점이 있다.In this design, the hexagon nut and the wing plate body are separately made and the hexagonal protrusion formed in the coupling part of the hexagon nut is forcibly coupled to the hexagonal coupling hole of the wing plate body, so that the hexagon nut and the wing plate body are combined without relaxation It has the advantage of being able to select various specifications of the hexagon nut and the wing plate body, and since the hexagon nut and the wing plate body are separately made and combined, the production efficiency can be increased, so productivity is improved, the occurrence of defective products is small, and the standard is various It has the advantage of being able to mass-produce the product, thereby achieving competitive product production, and making and supplying durable products.
특히, 본 고안은 육각너트를 윙판체 위에서 결합할 때는 육각형돌출부가 육각형구멍에 끼워지면 단턱(1d")에 제어되어 정지되고, 용접으로 고정되며, 육각너트를 윙판체 밑에서 끼울 때는 하단접촉판(1c)에 정지되므로 정밀한 결합이 이루어진다.In particular, when the hexagonal nut is coupled on the wing plate body, the present invention is controlled and stopped on the step (1d") when the hexagonal protrusion is inserted into the hexagonal hole, and is fixed by welding. Since it stops at 1c), precise coupling is made.
