Tapered Plate(LP PLATE) 개요         <TABLE border=0 cellSpacing=0 cellPadding=0 width="100%"> <TBODY> <TR> <TD width="2%"><IMG src="https://img1.daumcdn.net/relay/cafe/original/?fname=http%3A%2F%2Fwww.steel-n.com%2Fesales%2Fgeneral%2Fkr%2Fimages%2Fempty.gif" width=40 height=1></TD> <TD width="98%"> 변단면후판(Tapered Plate)은 길이방향으로 두께가 연속적으로 변하는 신개념의 후판제품으로 강구조물 적용시 발생하는 단면력에 대응하여 강재를 더욱 효율적으로 사용할 수 있어 강재량을 절감할 수 있으며 용접부를 감소시킬 수 있다. 특히 길이 방향으로 두께가 변하는 강판을 LP Plate(Longtudinal Profiled Plate)라고 한다.     <TABLE border=0

height=9> 자중 및 재료비의 감소   강구조 부재의 응력변화에 따라 이상적인 판 두께에 가까운 두께 변화가 가능하기 때문에 강재의 자중이 감소되고 재료비가 적게 든다.     <IMG src="https://img1.daumcdn.net/relay/cafe/original/?fname=http%3A%2F%2Fwww.steel-n.com%2Fesales%2Fgeneral%2Fkr%2Fimages%2Farrow01.gif" width=9 height=9> 공기 단축 및 제작비 감소   후판 제조과정에서 두께를 다양하게 변화시킬 수 있으므로 기존의 강구조 부재 제작에서 용접부의 개소를 크게 줄일 수 있어 공기단축이 가능하고 제작비가 적게 든다.      품질의 우수성       공장 제작이므로 용접 이음부가 매끄러워 기존의 후판을 용접하여 제작하는 경우보다 우수한 품질을 얻을 수 있다.     <IMG src="https://img1.daumcdn.net/relay/cafe/original/?fname=http%3A%2F%2Fwww.steel-n.com%2Fesales%2Fgeneral%2Fkr%2Fimages%2Farrow01.gif" width=9 height=9> 피로성능의 향상 및 유지관리     용접이음부 개소의 감소로 노치부를 줄일수 있으며, 강구조 부재 제작 Tapered Plate를 적절히 배치하여 피로 취약지점의 용접을 피할 수 있어 피로성능이 향상됩니다. 강구조물의 유지보수 측면에서도 점검개소가 감소되고 점검주기도 길어져 전체적 유지관리 측면에서 유리합니다.       3. 두께 변화에 따른 경제성 비교             (제작방법 비교)         <TABLE border=0
