METHOD OF BUILDING PLATE TO CIRCUMFERENCE IN APERTURE OF HORIZONTAL BORE AND BUILDING TOOL FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method and tool capable of efficiently building a plate to the circumference in the aperture of a sleeve bore while holding the sleeve bore horizontal. SOLUTION: The building tool 5 having an expansion and contraction type tool body 6 to be engaged and attached with and to the edge of the sleeve bore 2 in positions at three points in a circumferential direction by extending from a shortened state within the sleeve bore 2 and receiving sections 7 projecting to the outside of the sleeve bore 2 from the tool body 6 in the attaching state is used and this building tool 5 is attached into the sleeve bore 2. The receiving sections 7 and 7 of the tool 5 are made to receive the inner peripheral part of an escape bore 3 of the plate 4 to put the plate 4 into the state that the plate is built to the circumference in the aperture of the sleeve bore 2.
