JOINT PLACE WITH GROOVE AND STEEL MATERIAL JOINT STRUCTURE
To provide a joint plate with a groove that can obtain a high slip factor, and a steel material joint structure which facilitates joint work and is resistant to shearing force.SOLUTION: A joint plate 100 with a groove is provided with a plurality of projecting portions 13 and groove portions 11 aligned in parallel, on at least one surface contacting with a joint target. The projecting portions 13 are isosceles triangles (or regular triangles), and the projecting portions 13 and the groove portions 11 are aligned at equal pitches p1. Arc-shaped portions are formed in bottom portions of the groove portions 11, and have a round-shape. Meanwhile, tip ends of the projecting portions 13 are formed to be sharp with respect to the shape of the bottom portions of the groove portions 11. The tip ends of at least a part of the projecting portions 13 are formed so as to deviate in a side-by-side disposing direction of the projecting portions 13 with respect to an ideal projecting shape E formed by extension lines of inclined surfaces of the projecting portions 13.SELECTED DRAWING: Figure 3
【課題】 高いすべり係数が得られる溝付接合板及び接合作業が容易であり、せん断力にも強い鋼材接合構造を提供する。【解決手段】 溝付接合板１００は、接合対象に接する少なくとも一方の面に、複数の突部１３及び溝部１１が平行に並べて設けられる。突部１３は、略二等辺三角形（又は正三角形）であり、突部１３および溝部１１は等ピッチｐ１で配列されている。溝部１１の底部には円弧部が形成され、丸みを帯びている。一方、突部１３の先端は、溝部１１の底部形状に対して鋭利に形成されている。また、少なくとも一部の突部１３の先端が、突部１３の斜面の延長線で形成される理想突形状Ｅに対して、突部１３の併設方向へずれた向きになるように形成される。【選択図】図３
