In addition, in a cross section orthogonal to the axial direction, the relative distance between the first opposite side portion 54 of the first inclined surface sliding member 5 and the second opposite side portion 64 of the second inclined surface sliding member 6. Becomes larger. In the steel beam 31 and the splice plate 34, the first inclined surface sliding member 5 and the second inclined surface sliding member 6 are rod-shaped members inside the respective through holes (first through hole 331, second through hole 341). It is inserted together with 7 from one direction in the plate thickness direction of the web 33. Then, one of the first inclined surface sliding member 5 and the second inclined surface sliding member 6 is pressed toward the other inside the first through hole 331 and the second through hole 341. Then, the first opposite side portion 54 of the first inclined surface sliding member 5 and the second opposite side portion 64 of the second inclined surface sliding member 6 are separated from each other, and the first through hole 331 and the second through hole 341 Since the inner peripheral surface is pressed to move the hole position, the alignment of the first through hole 331 and the second through hole 341 is performed.

As described above, the through-hole alignment jig 1 according to some embodiments includes the first inclined surface sliding member 5 having the first inclined surface 51 and the first insertion hole 52 described above, and the first inclined surface sliding member 5 described above. It is inserted into the second inclined surface sliding member 6 having the second inclined surface 61 facing the inclined surface 51 and the first insertion hole 52 of the first inclined surface sliding member 5 described above, and the second inclined surface sliding.

As shown in FIGS. 1 and 2, the pair of inclined surface sliding members 4 includes a first inclined surface sliding member 5 having a first inclined surface 51 inclined with respect to the axial direction of the rod-shaped member 7, and a rod-shaped member. It includes a second inclined surface sliding member 6 which is inclined with respect to the axial direction of 7 and has a second inclined surface 61 facing the first inclined surface 51. Therefore, when one of the first inclined surface sliding member 5 and the second inclined surface sliding member 6 is pressed toward the other, the first inclined surface 51 of the first inclined surface sliding member 5 and the second inclined surface sliding member 5 are pressed. The second inclined surface 61 of the inclined surface sliding member 6 is engaged with each other, and the first inclined surface sliding member 5 and the second inclined surface sliding member 6 are on the other inclined surface (first inclined surface 51). , Slides along the second inclined surface 61).

By moving the constituent members 3 apart from each other and in contact with the inner circumference of the through holes 30 of the constituent members 3, the through holes 30 are aligned with each other. Therefore, the through-holes 30 can be easily aligned with each other by the through-hole alignment jig 1.

Further, since the rod-shaped member 7 is inserted into the first insertion hole 52 of the first inclined surface sliding member 5 and attached to the second inclined surface sliding member 6, the first inclined surface sliding member 5 And the second inclined surface sliding member 6 are not separated from the rod-shaped member 7 by a certain distance or more. Therefore, when the rod-shaped member 7 is inserted into the through hole 30, the first inclined surface sliding member and the fifth inclined surface sliding member 6 can be inserted into the through hole 30 together with the rod-shaped member 7. The alignment jig 1 can be easily inserted into the through hole 30.

In some embodiments, as shown in FIGS. 1 and 2, the rod-shaped member 7 is loosely inserted into the first insertion hole 52 described above. In this case, since the rod-shaped member 7 is loosely inserted into the first insertion hole 52, the first inclined surface sliding member 5 moves along the direction orthogonal to the axial direction of the rod-shaped member 7 with respect to the rod-shaped member 7. It is easy to do. Therefore, as the first inclined surface sliding member 5 and the second inclined surface sliding member 6 slide along the other inclined surface (first inclined surface 51, second inclined surface 61), the first Since the opposite side portion 54 and the second opposite side portion 64 can be easily separated from each other, the through holes 30 can be easily aligned with each other.

Further, the first locking member 8 may be fixed by, for example, fitting to a rod-shaped member 7 having no male screw portion 71.

According to the above configuration, the second inclined surface sliding member 6 has a second insertion hole 62 extending along the axial direction of the rod-shaped member 7 and loosely inserting the rod-shaped member 7. Therefore, since the rod-shaped member 7 is loosely inserted into the second insertion hole 62, the second inclined surface sliding member 6 moves along the direction orthogonal to the axial direction of the rod-shaped member 7 with respect to the rod-shaped member 7. Is easy. Therefore, as the first inclined surface sliding member 5 and the second inclined surface sliding member 6 slide along the other inclined surface (first inclined surface 51, second inclined surface 61), the first Since the opposite side portion 54 and the second opposite side portion 64 can be easily separated from each other, the through holes 30 can be easily aligned with each other.

Further, the through hole positioning jig 1 includes a first locking member 8 that is supported by the rod-shaped member 7 and restricts the relative movement of the second inclined surface sliding member 6 with respect to the rod-shaped member 7. Therefore, when a force that pushes one of the first inclined surface sliding member 5 and the second inclined surface sliding member 6 toward the other acts, the second inclined surface sliding member 6 engages with the first. Since the stop member 8 restricts the movement along the axial direction, the above-mentioned force is used to slide the first inclined surface sliding member 5 and the second inclined surface sliding member 6 along the other inclined surface. It can be used as power.

The through-hole alignment jig 1 described above further includes a second locking member 9 that is screwed into the male screw portion 71 of the rod-shaped member 7 so as to be relatively movable. As shown in FIGS. 1 and 2, the second locking member 9 is on the side opposite to the second inclined surface sliding member 6 with respect to the first inclined surface sliding member 5 in the axial direction of the rod-shaped member 7. Is located in. According to the above configuration, the through hole positioning jig 1 includes a second locking member 9 that is screwed into the male screw portion 71 of the rod-shaped member 7 so as to be relatively movable. Therefore, by simply rotating either the rod-shaped member 7 or the second locking member 9 relative to the other, one of the first inclined surface sliding member 5 and the second inclined surface sliding member 6 can be rotated. A pressing force can be applied to the other side. Therefore, the through-holes 30 can be easily aligned with each other by the through-hole alignment jig 1.

In some of the above-described embodiments, both the first inclined surface sliding member 5 and the second inclined surface sliding member 6 are along the direction orthogonal to the axial direction of the rod-shaped member 7 with respect to the rod-shaped member 7.
