STEEL PIPE CONNECTION STRUCTURE
To provide a steel pipe connection structure with high economical efficiency.SOLUTION: A radius ρ1 of a second outward angle part 32e continuous to a pin joint side non-transmission surface 32d opposite to a pin joint side transmission surface 32b in an outward groove and a radius ρ2 of curvature of a second inward angle part 42e continuous to a box joint side non-transmission surface 42d opposite to a box joint side transmission surface 42b in an inward groove 42 are larger than a radius ρ3 of curvature of a first outward angle part 32c continuous to a pin joint side transmission surface 32b transmitting a tensile load between a load transmission key 7 and the pin joint side transmission surface in the outward groove and a radius ρ4 of curvature of a first inward angle part 42c continuous to a box joint side transmission surface 42b transmitting a tensile load between the load transmission key 7 and the box joint side transmission surface in the internal groove 42.SELECTED DRAWING: Figure 2
【課題】経済性の高い鋼管連結構造を提供する。【解決手段】外向溝のうち、荷重伝達キー７との間で引張荷重を伝達するピン継手側伝達面３２ｂに連なる第一外向角部３２ｃの曲率半径ρ３、及び内向溝４２のうち、荷重伝達キー７との間で引張荷重を伝達するボックス継手側伝達面４２ｂに連なる第一内向角部４２ｃの曲率半径ρ４よりも、外向溝のうち、ピン継手側伝達面３２ｂに対向するピン継手側非伝達面３２ｄに連なる第二外向角部３２ｅの曲率半径ρ１、及び内向溝４２のうち、ボックス継手側伝達面４２ｂに対向するボックス継手側非伝達面４２ｄに連なる第二内向角部４２ｅの曲率半径ρ２ほうが大きく構成されている。【選択図】図２
