PROBLEM TO BE SOLVED: To provide an L type connecting fitting with improved strength.SOLUTION: The L-shaped coupling fitting 1 has a first fixing surface 10 and a second fixing surface 20 formed by vertically bending a single rectangular plate along fold lines orthogonal to its longitudinal direction, and in the first fixing surface 10, the first mounting hole 11 is formed, the second fixing surface 20 is formed with the second mounting hole 21, and the vertically bent portion is provided with a reinforcing large rib 30 for reinforcement projecting inward over the entire width direction. A first edge folding portion 15 for reinforcement bent inward is formed on both edges of the first fixing surface 10, and on the two edges of the second fixing surface 20, a reinforcing second edge bent portion 25 bent inward is formed.SELECTED DRAWING: Figure 1
【課題】強度の向上したＬ型連結金具を提供する。【解決手段】Ｌ型連結金具１は、一枚の長方形状板をその長手方向に直交する折り目に沿って垂直に折り曲げることで形成される第一固定面１０及び第二固定面２０を備え、第一固定面１０には、第一取付穴１１が形成され、第二固定面２０には、第二取付穴２１が形成され、垂直に折り曲げた部分には、幅方向全体にわたって内側に突出する補強用の大型リブ３０が形成されている。また、第一固定面１０の両縁には、内側に折り曲げられた補強用の第一縁折曲げ部１５が形成され、第二固定面２０の両縁には、内側に折り曲げられた補強用の第二縁折曲げ部２５が形成されている。【選択図】図１
