본 고안은 콘크리이트 전주에 스텝보울트를 결합시 사용되는 너트를 정확한 위치에 정한한 각도로 견고하게 부착시킬 수 있는전주용 스텝너트에 관한 것이다.The present invention relates to a step nut for poles that can firmly attach the nut used to couple the step bolt to the concrete pole at an angle determined at the correct position.
종래의 스텝너트는 원통체의 내주연에 단순히 나사만을 형성시켰으므로 콘크리트 원주내에 스텝너트를 정위치에 정각도록 고정시켜 콘크리이트 모르타르를 넣어 응결시키기에 작업이 매우 까다로웠고 작업도중 너트의 각도가 조금 틀어져도 보울트를 제 위치에 체결시킬 수가 없었다.Since the conventional step nut simply formed a screw on the inner circumference of the cylindrical body, the step nut was fixed to the right position in the concrete circumference so that it was very difficult to condense the concrete mortar and condense it. A slight twist could not lock the bolt in place.
본 고안은 이와 같은 결점을 시정하고자 원통체 너트의 외주연에 삽입공이 천동된 수개의 고정돌기를 돌설시켜 콘크리이트 전주 내부의 골격철사로서 정위치에 획고하게 고정시키고 원통체 입구의 선단에는 보울트의 고정돌출구가 삽입될 요입환을 형성시켜 와셔가 없이도 견고하게 보울트를 체결시킬 수 있는 것으로서 도면에 의거 상세히 설명하면 다음과 같다.In order to correct this defect, the present invention protrudes a number of fixing projections in which the insertion hole is driven to the outer circumference of the cylindrical nut to fix it firmly in place as skeletal wire inside the concrete pole. Forming the inlet ring to be inserted into the fixed protrusion can be fastened bolts without a washer as described in detail based on the drawings as follows.
내주연에 나사(11)가 형성된 공지의 원통체너트(10)에 있어서, 외주연 후단에 걸림돌출구(13)를 돌설시키고 외주연에는 삽입공(12')이 천동괸 수개의 고정돌기(12)를 돌시시키고 외주연 선단에는 보울트(20)의 고정돌출구(21)가 삽입될 원통체보다 큰 외경의 고정삽입환(14)을 형성시켜서된 것이다.In the well-known cylindrical cylinder nut 10 in which the screw 11 is formed in the inner periphery, the locking projection 13 is protruded at the rear end of the outer periphery, and the insertion hole 12 'is perforated at the outer periphery. ) And a fixed insertion ring 14 having an outer diameter larger than that of the cylindrical body to which the fixed protrusion 21 of the bolt 20 is inserted.
이와 같은 구조로된 본 고안은 원통체 너트 외주연에 삽입공(12')이 천공된 고정돌기(12)를 수개 돌설시켰으므로 콘크리이트 모르타르를 넣기전에 골격철사로서 고정돌기의 삽입공을 상호끼워서 원주골격에 너트를 확고하게 부착 시키므로서 너트를 정위치에 정각도로서 견고하게 고정시킬 수가 있고 콘크리이트 모르타르를 넣고 작업시에는 부착된 너트가 움직이지 않고 정위치에 수직상태를 유지시켜주므로 작업이 용이하며, 외주연 선단에는 원통체보다 큰 외경의 고정삽입환(14)을 형성 시켰으므로 보울트나사로서 체결시 너트의 나사에 삽입되면서 보울트의 고정돌출구(21)가 고정삽입환(14)에 완전 일치되게 삽입되므로 와셔가 필요 없이 견고하게 결합되는 것이다.The present invention having such a structure has a number of fixing protrusions 12 having a hole 12 'formed on the outer circumference of the cylindrical nut, so that the insertion holes of the fixing protrusions are interwoven with skeletal wires before the concrete mortar is inserted. By attaching the nut to the circumferential frame firmly, the nut can be fixed firmly in the right position at the right angle.In case of inserting the concrete mortar, the attached nut does not move and maintains the vertical position at the right position. Since the fixed end of the outer diameter is formed into a fixed insertion ring 14 having a larger diameter than the cylindrical body, the fixing protrusion 21 of the bolt is completely inserted into the fixed insertion ring 14 while being inserted into the screw of the nut when tightening as a bolt screw. Since they are matched, the washers are firmly joined without the need.
