To provide a web frame attachment structure capable of reducing concentration of stress in a junction between a lower end of a web frame and a bottom upper surface plate.SOLUTION: A web frame attachment structure for an automobile carrying vessel connects a web frame 3 attached to extend in a vertical direction inside a vessel side plate of a vessel and a lower end part of the web frame 3 to a bottom upper surface plate 5 of a bottom using a bracket 6. The bracket 6 is an approximately triangular plate material composed of a bottom side, an upright side, and an oblique side, the upright side is fixed to the lower end part of the web frame 3, the bottom side is fixed to the bottom upper surface plate 5, and an upper edge has a curved indention 10 formed indented in arcs 11, 12 in two positions in a tip part of the oblique side. The first arc 11 formed on a distal end among the arcs in two position has a small curvature radius, and the second arc 12 formed more inside than the distal end has a great curvature radius. Concentration of stress is capable of being reduced by absorbing an external force at the curved indention 10 in the bracket 6.SELECTED DRAWING: Figure 2

    【課題】ウェブフレームの下端と船底上面板との接合部において応力集中を低減できるウェブフレーム取付構造を提供する。【解決手段】船舶の船側板の内側に上下方向に延びるように取付けられるウェブフレーム3と、ウェブフレーム3の下端部を船底の船底上面板5にブラケット6を用いて接続している。ブラケット6は底辺と直立辺と斜辺とからなる略三角形の板材であり、直立辺はウェブフレーム3の下端部に固定され、底辺は船底上面板5に固定されており、斜辺の先端部において、その上縁が2カ所の円弧11,12で凹む湾曲凹部10が形成されている。2カ所の円弧のうち斜辺の最先端に形成される第1の円弧11は曲率半径が小さく、最先端より内側に形成される第2の円弧12は曲率半径が大きい。ブラケット6の湾曲凹部10において外力を吸収し応力集中を低減できる。【選択図】図2
