Abstract

PURPOSE: To carry out work safely without damaging a mating face by composing a mating face separating device of an internal thread machined in a fastening bolt through-hole of an equipment casing with the mating face, and a pressing bolt screwed into the internal thread to jack up. CONSTITUTION: A flange 10 is provided with a bolt hole 12 with an internal thread machined in a conventional through-hole pierced with a mating face fastening bolt. A flange 11 is provided with a bolt hole 13. A straight part 17 of a pressing bolt 14 is so formed that its length A is longer than the depth B of the bolt hole 13 and that its outer diameter C is smaller than the inner diameter D of the bolt hole 13. At the time of separating the mating faces of the flanges 10, 11, the pressing bolt 14 is screwed into the bolt hole 12 and further screwed in after the tip of the stragiht part 17 comes in contact with the bottom part of the bolt hole 13. The flange part 10 is therefore jacked up to separate the mating faces.
