Utility Model Publication No. 62-32146

To align the through holes with each other using the beam attachment jig described in Patent Document 1, it is necessary for the operator to move the beam attachment jig while making fine adjustments so that the through holes are aligned with each other. Therefore, workability depends on the number of years of experience and skill level of the operator. Therefore, there is a possibility that the through holes formed in each of the plurality of structural members constituting the structure cannot be easily aligned.

In view of the above-mentioned circumstances, an object of at least one embodiment of the present invention is to provide through-hole alignment that allows easy alignment of through-holes formed in each of a plurality of structural members constituting a structure. The goal is to provide jigs.

(1) The through-hole positioning jig according to at least one embodiment of the present invention includes:
A through-hole positioning jig for aligning through-holes formed in each of a plurality of structural members constituting a structure,
a first inclined surface sliding member having a first inclined surface whose outer dimension gradually decreases from the distal end side to the proximal end side;
a second inclined surface sliding member having a second inclined surface whose outer dimension gradually decreases from the distal end side to the proximal end side, the second inclined surface capable of sliding with respect to the first inclined surface; , comprising;
The first inclined surface sliding member and the second inclined surface sliding member are configured to be insertable into the through hole in a state where the first inclined surface and the second inclined surface face each other. .

According to the configuration (1) above, the through-hole positioning jig is arranged so that the first inclined surface sliding member and the second inclined surface slide in a state where the first inclined surface and the second inclined surface face each other. When at least one of the first inclined surface sliding member and the second inclined surface sliding member is pulled after inserting the member into the through hole formed in each of the plurality of constituent members, the first inclined surface sliding member is pulled. The member and the second inclined surface sliding member slide along the other inclined surface.

As the first inclined surface sliding member and the second inclined surface sliding member slide along the other inclined surface, the inclined surfaces of the first inclined surface sliding member and the second inclined surface sliding member are The through holes are aligned by moving the opposite parts apart from each other (increasing the diameter) and moving the component by contacting the inner periphery of the through hole of the component. Therefore, the through holes can be easily aligned with each other using the through hole positioning jig.

(2) In some embodiments, in the through-hole positioning jig described in (1) above, the second sloped surface sliding member is configured to be connected to the first sloped surface sliding member and the second sloped surface sliding member. A stopper member is provided on the proximal end side of the second inclined surface sliding member and comes into contact with the surface of the component in which the through hole is formed when the moving member is inserted into the through hole.

According to configuration (2) above, when the first inclined surface sliding member is pulled while the stopper member is in contact with the surface of the component in which the through hole is formed, the second inclined surface sliding member is moved from the base. Since movement in the tensile direction is restricted by the stopper member provided on the end side, the movement of the first inclined surface sliding member is smaller than if the stopper member was not provided on the proximal end side of the second inclined surface sliding member. A large tensile force can be applied to the inclined surface of the moving member and the inclined surface of the second inclined surface sliding member. When the force acting on the inclined surface of the first inclined surface sliding member and the inclined surface of the second inclined surface sliding member is large, the first inclined surface sliding member and the second inclined surface sliding member move toward the other inclined surface. Since it is possible to smoothly slide along the axial direction and move the component members smoothly, it is possible to improve the working efficiency of positioning a plurality of through holes using the through hole positioning jig.

(3) In some embodiments, in the through-hole positioning jig described in (2) above, the stopper member is removably provided on the proximal end side of the second inclined surface sliding member.
According to the configuration (3) above, when the stopper member is removed from the second slope sliding member, the first slope sliding member and the second slope sliding member are attached to each of the plurality of constituent members. By inserting into the formed through-hole, the insertion work into the through-hole can be performed quickly.

(4) In some embodiments, in the through-hole positioning jig described in (2) above, the stopper member moves from the first state to the second state on the proximal end side of the second inclined surface sliding member. state, and the stopper member is provided to be changeable from the second state to the first state, and the first state is a state of the stopper member that allows the second inclined surface sliding member to be inserted into the through hole; In the second state, when the second inclined surface sliding member is inserted into the through hole, the stopper member is capable of abutting the stopper member against the surface of the constituent member in which the through hole is formed. The through-hole positioning jig includes operating means provided on the proximal end side of the first inclined surface sliding member, and by operating the operating means, the state of the stopper member can be adjusted. , further comprising a variable mechanism configured to be changeable from the first state to the second state, and from the second state to the first state.

According to the configuration (4) above, the state of the stopper member is changed from the first state to the second state and from the second state to the first state by the operating means provided on the base end side of the first inclined surface sliding member. It can be changed. By placing the stopper member in the first state, the second inclined surface sliding member can be inserted into the through hole, and the second inclined surface sliding member can be pulled out from the through hole. Furthermore, when the first inclined surface sliding member is pulled while the stopper member is in the second state, that is, in contact with the surface of the component where the through hole is formed, the second inclined surface sliding member moves toward the proximal side. Since the provided stopper member restricts the movement in the tensile direction, the movement of the first inclined surface sliding member is reduced compared to a case where the stopper member is not provided on the proximal end side of the second inclined surface sliding member. A large tensile force can be applied to the inclined surface and the inclined surface of the second inclined surface sliding member, and as a result, it is possible to improve the working efficiency of positioning a plurality of through holes using the through hole positioning jig.

In addition, the insertion work of the first slope sliding member and the second slope sliding member into the through hole, the pulling out work from the through hole, and the operation by the operating means are performed at the base end of the first slope sliding member. It can be done from the side. In other words, since a series of operations for aligning the through holes using the through hole positioning jig can be performed from the base end side of the first inclined surface sliding member, the positions of the multiple through holes using the through hole positioning jig can be performed from the base end side of the first inclined surface sliding member. It is possible to improve the work efficiency of alignment.

(5) In some embodiments, in the through-hole positioning jig according to any one of (1) to (4) above, the second sloped surface sliding member may be lower than the second sloped surface. The through hole positioning jig has a stepped surface provided on an end side and faces the end surface on the distal side of the first inclined surface sliding member, and the through hole positioning jig has a longitudinal direction, and the through hole positioning jig has a longitudinal direction. The connecting member is configured to be expandable and contractible in the longitudinal direction, and one end of the connecting member in the longitudinal direction is fixed to the end face of the first inclined surface sliding member on the distal end side, and The other end is fixed to the stepped surface of the second inclined surface sliding member.

According to the configuration (5) above, since the connecting member can prevent one of the first inclined surface sliding member and the second inclined surface sliding member from detaching from the other, multiple It is possible to improve the work efficiency of aligning the through holes. Furthermore, one longitudinal end of the connecting member is fixed to the end face on the distal end side of the first inclined surface sliding member, and the other longitudinal end is fixed to the step surface of the second inclined surface sliding member. Therefore, the connecting member does not interfere with the alignment work of the plurality of through holes by the through hole positioning jig, such as the work of inserting the first slope sliding member and the second slope sliding member into the through holes. There is no.

(6) The through-hole positioning method according to at least one embodiment of the present invention includes:
A through-hole alignment method for aligning the through-holes with each other using the through-hole alignment jig according to any one of (1) to (5) above, wherein the first inclined surface and the second inclined surface an insertion step of inserting the first sloped surface sliding member and the second sloped surface sliding member into the through hole in a state where the first sloped surface sliding member and the second sloped surface sliding member face each other; An inclination that causes one of the first inclined surface sliding member and the second inclined surface sliding member to slide along an inclined surface that the other has by pulling at least one of the member and the second inclined surface sliding member. A surface sliding step.

According to the method (6) above, in the insertion step, when the first inclined surface and the second inclined surface face each other, the first inclined surface sliding member and the second inclined surface sliding member It is inserted into a through hole formed in each of the constituent members. In the slope sliding step, at least one of the first slope sliding member and the second slope sliding member is pulled in a direction away from the other. By pulling at least one of the first slope sliding member and the second slope sliding member, the first slope sliding member and the second slope sliding member slide along the slope of the other. .

As the first slope sliding member and the second slope sliding member slide along the slope of the other, the slopes of the first slope sliding member and the second slope sliding member slide. The through holes are aligned with each other by separating the opposing portions from each other (enlarging the diameter) and moving the component by contacting the inner periphery of the through hole of the component. Therefore, according to the above method, it is possible to easily align a plurality of through holes using the through hole positioning jig.

According to at least one embodiment of the present invention, a through-hole positioning jig is provided that can easily align through-holes formed in each of a plurality of structural members constituting a structure.

In some embodiments, the above-described through-hole positioning jig 1 uses the above-described second inclined surface sliding movement when aligning the plurality of through-holes 4 as shown in FIGS. 7 and 8, for example. A restricting means 40 is provided for restricting movement of the member 30 in the tensile direction. In the embodiment shown in FIGS. 7 and 8, the restricting means 40 has one end fixed to the distal end side of the second inclined surface sliding member 30, and the other end extending along the axial direction in the tensile direction. It includes a rod-shaped member 41.

As shown in FIG. 7, the rod-shaped member 41 has a male threaded portion 411 formed in at least a portion thereof including the distal end side of the outer periphery. The rod-shaped member 41 has a male threaded portion 411 formed on the distal end side that is more tensile than the screw hole 38 that opens in the second distal end surface 34 of the second inclined surface sliding member 30 and the second inclined surface sliding member 30 . It is fixed to the second inclined surface sliding member 30 by screwing into the nut 42 located on the direction side. Note that in other embodiments, the tip of the rod-like member 41 that does not have the male threaded portion 411 fits into the hole formed in the second slope sliding member 30, so that the rod-like member 41 is connected to the second slope surface. It may be fixed to the sliding member 30.

The first inclined surface sliding member 20 is configured such that the nut 42 can be disposed between the first stepped surface 25 and the second end surface 34 of the second inclined surface sliding member 30, as shown in FIGS. 7 and 8.
