Therefore, there is a problem that the surface 21 may be dented and crushed depending on the tightening condition.

Similarly, the access frame 10 and the partition stud 20
In order to eliminate the gap created between
By tightening too much, the screw groove formed in the frame 10 is broken, causing a so-called screw stupid phenomenon,
There is a problem that the fastening with the screw nail 100 may not be effective, and it is difficult to secure stable attachment strength.

The present invention has been made in view of the above-mentioned problems, and in a building such as a house, a partition wall is formed on an entrance / exit frame made of wood or wood plywood forming a frame body for securing an opening. An object of the present invention is to provide a fixing method which does not crush the surface of the partition studs when fixing the tubular partition studs made of a thin steel plate or the like, or between the partition studs.

The partition stud 20 is a long tubular body made of a thin steel plate, and its cross section is formed in a substantially rectangular shape. Here, the thickness of the thin plate that constitutes the partition stud 20 is not particularly limited as long as it is sufficiently thin as compared with the length of the second screw portion 35 of the screw nail 30 described later.

As shown in FIG. 2, the screw nail 30 has a shaft body 31 having a substantially cylindrical shape with the same outer diameter (valley diameter),
A substantially dish-shaped head 32 provided at the base end of the shaft body 31,
It consists of a tapered sharpened portion 33 provided at the tip. The shaft body 31 has a first screw portion 34 formed on the tip side.
And a second screw portion 35 formed on the base end side, and its length is set to be sufficiently longer than the thickness of the partition stud 20 (see FIG. 5). Although not shown, the upper end surface of the head 32 can be engaged with a rotary engaging portion at the tip of a rotary tightening tool such as a driver.
A groove having a one-letter shape or a cross shape is formed.

The pointed portion 33 is formed in a substantially conical shape with the tip of the tip as an apex, and its maximum diameter is
It is set to be equal to or smaller than the outer diameter (valley diameter) of the shaft body 31. Further, threads are formed at the same pitch as the first screw portion 34.

In the present embodiment, the sharpened portion 33 is provided at the tip of the shaft body 31, but the sharpened portion 3 is provided.
Instead of 3, the cutting groove 36 is provided on the shaft 3 as shown in FIG.
Two drill portions 38 may be provided at symmetrical positions with respect to the center line of the axial direction of 1, and the cutting groove 37 may be formed at the edge of the cutting groove 36. The outer diameter of the drill portion 38 is set to be approximately the same as the outer diameter (valley diameter) of the shaft body 31, and is set smaller than the crest diameter of the screw thread of the first screw portion 34.

As shown in FIG. 2, the first threaded portion 34 is formed at the tip of the shaft body 31, and the boundary with the second threaded portion 35 is such that when the sharpened portion 33 is screwed into the take-in / out frame 10. The partition stud 20 is set longer than the thickness of the partition stud 20 so as to be located closer to the base end side than the surface 21 (upper side in FIG. 5). The shape of the first screw portion 34 is not limited to this, and as shown in FIG. 4, a non-screw portion 39 in which a screw thread is not formed may be provided on the base end side thereof.

As shown in FIG. 2, the second screw portion 35 is formed up to the base end of the shaft body 31, and the pitch of the screw thread is set to the first.
It is set to be larger than the screw portion 34, that is, the lead of the second screw portion 35 is longer than the lead of the first screw portion 34. Further, the thread diameter of the screw thread is set to be slightly larger than that of the first screw portion 34.

Next, the procedure for fixing the partition stud 20 to the frame 10 using the screw nail 30 as shown in FIGS. 1 and 5 to 7 will be described. First, as shown in FIG. 5, a partition stud 2 is formed on the surface 11 of the frame 10.
0 so that they are in close contact with each other, and then the surface of the partition stud 20 (upper side in the figure.
Say. ) 21 is applied to the predetermined tightening position of the screw nail 30, and the screw nail 30 is screwed downward from the partition stud 20 toward the in-out frame 10. Then, the screw nail 30 is screwed into the upper surface 21 of the partition stud 20 while rotating, and a lower hole is bored in the upper surface 21 to form the burr 2.
Form 2.

When the screw nail 30 is further tightened, the shaft body 31 advances in accordance with the pitch of the screw thread of the first screw portion 34, and the screw thread of the first screw portion 34 forms a thread groove in the burr 22. Go on. At this time, since the peak diameter of the first screw portion 34 is the same as or larger than the maximum diameter of the sharpened portion 33, the first screw portion 34
Will enter so as to widen the lower hole of the partition stud 20, and the burr 22 can be surely engraved with a thread groove.

When the screw nail 30 is continuously tightened,
When the sharpened portion 33 reaches the side surface (lower side in the drawing; hereinafter, referred to as “lower surface” in the drawing) 23 of the partition stud 20, a lower hole is formed similarly to the upper surface 21 to form a burr 24,
The tip reaches the surface 11 of the frame 10.

Here, after the tip of the pointed portion 33 reaches the surface 11 of the frame 10, and before the pointed portion 33 is smoothly screwed into the frame 10, the screw nail 30 slightly idles. As the shaft 31 moves along the thread grooves formed in the burrs 22 and 24 of the partition stud 20, a slight gap is created between the loading / unloading frame 10 and the partition stud 20. However, in the present embodiment, the access frame 10 is made of wood or wood plywood, and the partition studs 20 are made of thin steel plates, that is, the access frame 1
Since 0 is made of a material softer than the partition stud 20, the tip of the sharpened portion 33 is the lower surface 2 of the partition stud 20.
When 3 is reached, the screw nail 30 is screwed in at once with a strong force, so that a gap generated between the front surface 11 of the loading / unloading frame 10 and the lower surface 23 of the partition stud 20 can be suppressed.

Further, since the length of the first threaded portion 34 is set to be slightly longer than the thickness of the partition stud 20, when the tip of the sharpened portion 33 reaches the lower surface 23 of the partition stud 20, the first threaded portion is formed. Since the screw thread near the upper end of 34 is screwed into the thread groove formed in the burr 22 of the upper surface 21 of the partition stud 20, the screw nail 30 does not fall even if the screw nail 30 is screwed in at once with a strong force. .

Further, as shown in FIG. 4, the first screw portion 34
If the threadless portion 39 is formed on the base end side of the
When the front end of the partition stud 20 reaches the lower surface 23 of the partition stud 20, the non-threaded portion 39 is located in the burr 22 of the upper surface 21 of the partition stud 20, and the first threaded portion 34 is formed in the thread groove formed in the burr 22. Since the threads of are not screwed together,
The screw nail 30 can be screwed in with a stronger force.

Furthermore, when the drill portion 38 shown in FIG. 3 is used instead of the sharpened portion 33, the drilled portion 38 is replaced by the sharpened portion 3.
Since it can be quickly screwed into the frame 10 with a force stronger than 3, it is possible to prevent a gap from being formed between the surface 11 of the frame 10 and the lower surface 23 of the partition stud 20.

Then, as shown in FIG. 6, when the sharpened portion 33 is completely screwed into the inlet / outlet frame 10, the screw thread at the tip of the second screw portion 35 contacts the upper surface 21 of the partition stud 20. When the screw nail 30 is further tightened from here, the first and second holes are formed in the pilot hole formed by the sharpened portion 33 in the moving frame 10.
The screw thread on the front end side of the screw portion 34 is engraved with a screw groove, and the screw thread on the proximal end side is screwed into the screw groove, whereby the front end side of the first screw portion 34 is fixed to the inlet / outlet frame 10. It

Further, in the partition stud 20, a screw thread on the tip side of the second screw portion 35 is engraved on the burr 22 on the upper surface 21, and a screw thread on the base end side is screwed into the screw groove. And the first threaded portion 3 on the burr 24 on the lower surface 23.
The screw thread on the tip side of 4 engraves a screw groove, and the screw thread on the base end side is screwed into the screw groove, so that the base end side of the first screw portion 34 is in the burr 24 of the lower surface 23. Second screw portion 35
Are fixed to the burrs 22 on the upper surface 21, respectively. In this way, the partition stud 20 is fixed to the access frame 10.

Since the thread diameter of the thread of the second screw portion 35 is made slightly larger than that of the first screw portion 34, as described above, the second screw portion 35 has the upper surface 21 of the partition stud 20. The screw nail 30 enters as the lower hole is widened, and the partition stud 20 and the second screw portion 35 can be securely screwed together.

When the thread of the second screw portion 35 starts to enter while forming the screw groove in the burr 22 of the upper surface 21 of the partition stud 20, the second screw portion 35 is formed from the pitch of the thread of the first screw portion 34. Has a larger pitch, that is, the lead of the second screw portion 35 is larger than the lead of the screw thread of the first screw portion 34. Therefore, when the screw nail 30 is rotated once, the first screw portion The traveling distance of 34 is shorter than that of the second screw portion 35. That is, the distance traveled by the first screw portion 34 entering the burr 24 on the lower surface 23 of the entry / exit frame 10 and the partition stud 20 is the distance of the second screw portion 35 entering the burr 22 on the upper surface 21 of the partition stud 20. It is relatively shorter than the distance traveled. As a result, as shown in FIG. 7, the screw nail 30 is not tightened smoothly, and the upper surface 21 of the partition stud 20 bulges.

When the screw nail 30 is tightened at once from this state, as shown in FIG. 1, as the screw nail 30 enters, the bulge of the upper surface 22 of the partition stud 20 decreases. . Further, by tightening the screw nails 30 all at once until the bulge is eliminated, the partition stud 20 is fixed to the access frame 10 without the upper surface 21 of the partition stud 20 being dented and crushed.

At this time, since the second screw portion 35 is formed up to the base end of the shaft body 31, that is, just below the head portion 32, the screw nail 30 until the bulge of the upper surface 21 of the partition stud 20 is eliminated. By tightening, the head 32 of the screw nail 30 and the upper surface 21 of the stud 20 can be attached in close contact with each other.

Further, by using the screw nail 30 according to the present embodiment, as shown in FIG. 8, the partition studs 20 can be fixed to each other by the same procedure as in the present embodiment. Specifically, in the drawing, the lower partition stud 20
Then, the tip side of the first screw portion 34 is fixed to the burr 22 formed on the upper surface 21, and in the upper partition stud 20,
The burr 2 in which the base end side of the first screw portion 34 is formed on the lower surface 23.
4 and the second screw portion 35 is fixed to the burr 22 formed on the upper surface 21, respectively.

[0033]

As described above, according to the first aspect of the present invention.
According to the method of fixing the partition stud to the inlet / outlet frame described in (4), the pitch of the threads of the second screw portion of the screw nail is larger than the pitch of the threads of the first screw portion, that is, the screw threads of the second screw portion. Since the lead of is larger than the lead of the thread of the first screw part, when the second screw part reaches the partition stud, due to the difference of this lead, the screw nail cannot be tightened smoothly, which causes Since it is sufficient to tighten the screw nail until the swelling of the partition stud is eliminated, there is an advantage that it is easy to determine whether the screw nail is completely tightened.

As a result, it is possible to prevent overtightening of the screw nail, and there is an advantage that the surface of the partition stud is not crushed due to overtightening of the screw nail.

According to the method of fixing the partition stud to the inlet / outlet frame according to the second aspect of the present invention, since the screw nail is not screwed too much and the sharpened portion is tapered, it is formed in the inlet / outlet frame. There is an advantage that stable mounting strength can be secured without breaking the screw groove and causing a so-called stupid phenomenon.

According to the method of fixing the partition stud to the loading / unloading frame according to claim 3 of the present invention, the drilling portion is screwed into the loading / unloading frame at a stretch when the partition stud is passed through the loading / unloading frame. There is an advantage that it is possible to prevent a gap from being generated between the partition stud and the partition stud.
