Abstract

To provide a fixing method capable of suppressing damage of a first member and a second member when fixing the first member and the second member by using pins.SOLUTION: A fixing method according to one embodiment of this disclosure includes: a positioning process of positioning a plurality of holes (1a) formed on a first member (1) and a plurality of holes (2a) formed on a second member (2); an insertion process of inserting an expandable expansion pin (5) into each of a plurality of hole sets (4) each comprising the hole (1a) of the first member (1) and the hole (2a) of the second member (2) that are positioned; and a correction process of correcting positional shift between the hole (1a) of the first member (1) and the hole (2a) of the second member (2) by expanding the expansion pin (5) and maintaining an arrangement relation between the first member (1) and the second member (2).SELECTED DRAWING: Figure 4

Claims

1. A method for fixing a first member and a second member, which are flexible members, using a pin, A positioning step of aligning three or more holes formed in the first member and three or more holes formed in the second member, An insertion step of inserting expandable expansion pins into three or more sets of holes, each consisting of holes in the first member and holes in the second member that have been aligned; A correction step of expanding the expansion pin to correct the misalignment between the hole in the first member and the hole in the second member, and maintaining the positional relationship between the first member and the second member, Equipped with, The correction step involves simultaneously expanding the expansion pins inserted into the three or more sets of holes, and then stopping the expansion of the expansion pins in order, starting with the expansion pins inserted into the sets of holes where the misalignment between the holes of the first member and the holes of the second member has been corrected. A fixing method for fixing the first member and the second member by the expansion pin without leaving any other positioning pins in relation to the expansion pin.

2. The fixing method according to claim 1, wherein the expansion pin is expandable in diameter.

3. The outer diameter of the largest portion of the expansion pin when it is retracted is smaller than the diameter of the hole in the first member and the diameter of the hole in the second member. The fixing method according to claim 1 or 2, wherein the outer diameter of the largest portion of the expansion pin when it is expanded is greater than or equal to the diameter of the hole in the first member and the diameter of the hole in the second member.
