ない。2. Description of the Related Art When a joining member is joined to a base material having a shape such that the operation of tightening the nut to the bolt is limited to one side of the plate, such as a closed cross-sectional shape, the bolt is not attached to the base material. As shown in Fig. 4, a special high-strength bolt with a pin tail that can tighten the nut while gripping the shaft from the joining member side is used. Since it has a shape to be attached in contact with the base material, it cannot be used when it is attached by screwing the female screw formed in the base material from the joining member side.

を目視で確認することはできない。In order to screw the nut into the base material from the joining member side and tighten the nut, it is necessary to use a bolt having a threaded portion on both sides of the cylindrical portion, as in Japanese Utility Model Publication No. 5-575. With this special high-strength bolt, the pin tail formed on one thread side is gripped by the inner socket, and while it is fixed, the nut is turned by the outer socket, and the break groove between the thread part and the pin tail is twisted and broken with a constant torque. By doing so, a fixed axial force is introduced to the bolt when tightening of the nut is completed, but the screw groove on the base material side is also screwed in by grasping the pin tail and rotating it, so that the fracture groove yields. Since the screwing has been completed before, the magnitude of the torque at that time cannot be visually confirmed.

ので、母材への螺入時のトルク管理が行える締め付け方
法を提案しようとするものである。The present invention has been made in view of the above background, and an object thereof is to propose a tightening method capable of managing torque when screwing into a base material.

より一定のトルクで母材への螺入を行う。According to the present invention, the special high-strength bolt is formed with a screw-in pintail which is continuous with the tightening pintail of the screw portion on one side of the cylindrical portion and which sandwiches the breaking groove.
By breaking the fracture groove between the screwing pin tail and the tightening pin tail to complete the screwing of the screw portion on the base material side, the screwing into the base material is performed with a constant torque.

る。The special high-strength bolt has threaded portions opposite to each other on both sides of the cylindrical portion, is continuous with one threaded portion, and has two stages with a rupture groove sandwiched between the tightening pin tail on the screw side and the tip side. Since the threaded pin tail is formed, the yield torsion moment of the fracture groove between the tightening pin tail and the screw pin tail is smaller than the yield torsion moment of the fracture groove between the screw part and the tightening pin tail. Is set to a value corresponding to the torque applied when the threaded portion of is screwed into the base material.

り螺入時に与えるトルクが一定に管理される。It has been confirmed visually that the threaded portion on the base material side has been completely screwed into the base material due to the fact that the fracture groove between the tightening pin tail and the screwing pin tail is twisted and fractured, and this fracture groove is determined. By breaking at the yield torsion moment, the torque applied during screwing is controlled to be constant.

After completing the above, grasp the remaining tightening pin tail and rotate the nut in the fixed state to screw it into the screw part, twisting and breaking the break groove between the screw part and the tightening pin tail. Screwing of the nut is completed.

The yield torsion moment of the fracture groove 16 between 14 is smaller than the yield torsion moment of the fracture groove 15 between the threaded portion 12 and the pin tail 13 for tightening, and the threaded portion 11 on the base material 4 side is completely connected to the female screw 41. It is set to a size corresponding to the torque required for screwing. The yield torsion moment of the breaking groove 15 is set to a magnitude corresponding to the torque required to screw the nut 2 into the threaded portion 12 on the joining member 5 side.

破断した時点で螺入が完了する。As shown in FIG. 1, the threaded portion 11 is screwed into the female thread 41 by stacking the joining member 5 having the bolt insertion hole 51 larger than the cylindrical portion 10 on the base material 4 and inserting the threaded pin tail 14. It is carried out by gripping and rotating the inner socket 6, and the screwing is completed when the breaking groove 16 breaks due to a fixed yield torsion moment.

付時期は問われない。The joining member 5 is basically a female screw 41 of the screw portion 11.
Although it is piled up on the base material 4 when it is screwed into the base material 4, it may be piled up after the threaded portion 11 is screwed in, and the mounting time of the joining member 5 to the base material 4 does not matter.

However, since the screw directions of the screw portion 11 and the screw portion 12 are opposite to each other, the reaction force is applied. Is coincident with the rotation direction of the threaded portion 11 when screwed in, so that the reaction of the inner socket 6 prevents the threaded portion 11 from coming out of the base material 4.
