一种正交异性加劲板的加劲u肋双面焊结构

U rib both sides welding structure of putting more energy into of orthotropic stiffener

Abstract

本实用新型公开了一种正交异性加劲板的加劲U肋双面焊结构,它由钢面板、加劲U肋、第一外侧角焊缝、第二外侧角焊缝、第一内侧角焊缝、第二内侧角焊缝组成,其特征在于:加劲U肋与钢面板之间采用第一内侧角焊缝、第一外侧角焊缝双面焊的连接,加劲U肋与钢面板之间采用第二内侧角焊缝、第二外侧角焊缝双面焊的连接。构造简单,实施方便,改善了正交异性钢板结构的焊缝及焊缝部位钢面板及U肋的受力性能,提高了U肋与顶板间的焊接强度,改善了局部汽车、飞机轮载下钢面板与其U肋间焊接部位的耐疲劳性能。
The utility model discloses a U rib both sides welding structure of putting more energy into of orthotropic stiffener, it comprises steel facing, the U rib of putting more energy into, first outside angle welding, second outside angle welding, first medial angle welding seam, second medial angle welding seam, its characterized in that: put more energy into and adopt being connected of first medial angle welding seam, first outside angle welding both sides welding between U rib and the steel facing, adopt being connected of second medial angle welding seam, second outside angle welding both sides welding between put more energy into U rib and the steel facing. The simple structure, it is convenient to implement, has improved the atress performance of orthotropic steel plate structure's welding seam and welding seam position steel facing and U rib, has improved the welding strength between U rib and roof, has improved local automobile, aircraft wheel and has carried down the fatigue resistance of steel facing rather than U intercostal welding parts.
