十五万方储罐罐底边缘板与底圈壁板之间的大角焊缝接头
摘要：
十五万方储罐罐底边缘板与底圈壁板之间的大角焊缝接头，它涉及一种大型油库储罐罐底边缘板与底圈壁板的大角焊缝焊接接头。针对十五万方储罐的罐底边缘板与底圈壁板之间的大角焊缝接头处应力集中较大的问题。底圈壁板和罐底边缘板的厚度分别为40mm和23mm，罐底边缘板与底圈壁板之间的外角焊缝接头处的焊角高度和长度均为13mm，内角焊缝接头处的焊角高度和长度分别为13mm和20mm，内角焊缝接头处的底圈壁板的内表面上打坡口，坡口的高度和长度分别为13mm和5±1mm，内角焊缝接头处焊后表面磨成圆角半径为17mm的下凹圆弧，罐底边缘板与底圈壁板之间有长度为35mm的未完全焊透缝隙区域。本实用新型可以减小十五万方储罐大角焊缝接头处的应力集中。
摘要（英）：

A large fillet weld connector used between a tank bottom edge board and a foundation ring wallboard of a 150 thousand m<3> storage tank relates to the large fillet weld connector used between the tankbottom edge board and the foundation ring wallboard of the large-scale storage tank in an oil depot, aiming at solving the problem that the stress concentration at the large fillet weld connector used between the tank bottom edge board and the foundation ring wallboard of the 150 thousand m<3> storage tank is great. The thicknesses of the foundation ring wallboard and the tank bottom edge board are 40mm and 23mm respectively; both height and length of a weld fillet at an external angle weld joint connector between the tank bottom edge board and the foundation ring wallboard are 13mm; the height and the length of the weld fillet at an interior angle weld joint connector are 13mm and 20mm respectively; a bevel is formed on the inner surface of the foundation ring wallboard; the height and the length of the bevel are 13mm and 4, 5 or 6mm respectively; sunken circular arc is formed in a grinding manner on the welded surface at the interior angle weld joint connector, wherein, the radius of curvature of the sunken circular arc is 17mm; and an incomplete fusion gap area is formed between the tank bottom edge board and the foundation ring wallboard, and the length of the incomplete fusion gap area is 35mm. The large fillet weld connector can reduce the stress concentration at the large fillet weld connector of the 150 thousand m<3> storage tank.
