ことがないものである。 With this structure, the nut 6 screwed onto the male screw 4 and the washer 5 fitted therein are removed,
On the other hand, the thick timbers 10a, 10a to be connected
A predetermined through hole 11a, 1 is inserted in advance into which the main body 1 is inserted.
1b, and enlarged openings 12a, 12b are provided at the outer ends of the through holes 11a, 11b, into which the collar 2 and the washer 5 fit, respectively. The through hole 11a,
11b and then the other enlarged opening 12b.
Then, the washer 5 is fitted onto the male thread 4, and the nut 6 is screwed together. Next, the flange 2 provided at one end of the main body 1 is received by the step of the enlarged opening 12a, and the flange 2 is also provided at one end. If the main body 1 is temporarily fixed so that it does not rotate by locking an appropriate locking tool in the locking engagement part 7 for locking the locking tool, and then firmly tightening the nut 6, the other enlarged opening A washer 5 having a diameter larger than that of the main body 1 is pressed against the stepped portion of the main body 1, and the timbers 10a and 10b are clamped and fixed between the flange 2 of the main body 1 and the washer 6. Therefore, the anti-rotation tool was removed, and the nails 13 were driven into the wood 10a through the plurality of small nail-driving holes 3 provided in the collar 2, and the enlarged openings 12a, 12
If fillers 14a and 14b are filled in the holes 14a and 14b, the pieces of wood 10a and 10b will be reliably connected with a good-looking finish. Therefore, the main body 1 inserted into the timbers 10a and 10b connected in this way is not allowed to rotate because the flange 2 at one end is nailed, and the timbers 10a and 10b have hollow pipes. Since they come into contact with smooth arcuate surfaces, they will not easily be damaged even if a large load is repeatedly applied to the connection points.
