ある。In response to such a request, Japanese Patent Publication No. 7-919
No. 23 publication proposes a mounting method shown in FIGS. 7 and 8. According to this, when fixing the wooden frame 3 to the opening 2 formed in the wall, the wooden screw 4 as shown in FIG. 6 is used. In this wood screw 4, a screw thread 4b for screwing is formed on the tip side of a shaft body 4a, and a plurality of flange-shaped thin rings 4d are formed on the head part 4c side of the shaft body 4a.

３が開口部２に密着した状態までねじ込まれる。As shown in FIG. 7, the wooden frame 3 is composed of an inner wooden frame body 3a and a frame-shaped plywood part 3b surrounding the periphery thereof. Then, a concave portion 3c is formed at a position near the corner inside the vertical rail of the wooden frame 3 shown in FIG. 5, and the wood screw 4 of FIG. 6 is screwed in from here. In FIG. 7, the wood screw 4 penetrates the wood frame body 3 a and the plywood part 3 b, and is further screwed into the opening 2 of the wall 1. When the wood screw 4 is screwed into the opening 2, the thin-walled ring 4d resists screwing, but the screwing force of the screw thread 4b overcomes and the thin-walled ring 4d advances into the wooden frame 3 as shown in FIG. Is screwed in until the wooden frame 3 is in close contact with the opening 2.
【０００６】木ねじ４は、図５に示すように４個所にあ

口部２と同様に歪んでしまう。Since the wood screws 4 are provided at four places as shown in FIG. 5, all the wood screws 4 are shown in FIG.
When tightened so as to come into close contact with the opening 2, the wooden frame 3 is distorted similarly to the opening 2.

Stop the rotation of the wood screw 4 at the position where the vertical direction of the wooden frame 3 appears, and
The wooden frame 3 can be completely fixed to the opening 2 by filling an adhesive or the like into the gap 6 between the opening 2 and the opening 2.

３に歪みを残す原因となる。However, in the above-mentioned prior art, when the wood screw 4 is loosened, the wood screw 4 is moved to the position shown in FIG.
The thin-walled ring 4d tries to move the wooden frame 3 together with the wooden frame 3 to the right side in FIG. However, the coupling force between the thin ring 4d and the wooden frame 3 is weak, the wooden frame 3 is not moved, and the head 4c of the wooden screw 4 floats by d as shown in FIG. Therefore, even if the spacing s of the gap 6 is accurate, the floating d of the head 4c becomes unstable, which causes a distortion in the wooden frame 3.

The operation of will be described. Opening 2 in the wall 1 of the building
The wooden frame 3 is attached to the wooden screw 1 of the present invention.
1 is directly screwed into the wooden frame 3 having no recessed portion 3c by a driver or the like. The wood screw 11 enters the inside of the wooden frame 3 by the screw thread 13a on the tip side, but at this time, since the knurled blade 13b cuts the surrounding wood part, the wood screw 11 can be screwed with a small torque. , Easy to screw. Eventually, the tip of the wood screw 11 penetrates the wooden frame 3.

となる。The tip of the wood screw 11 that has passed through is continuously screwed into the opening 2 of the wall 1. After that, the tip of the screw thread 13c in the opposite direction reaches the surface of the wooden frame 3. For the screw thread 13c in the opposite direction, the screw thread 13a for screwing is in a loosening direction, which is a resistance against screwing.

The resistance force of c is made smaller than the screwing force of the screw thread 13a for screwing. Specifically, the pitch P1 of the reverse thread 13c is made larger than the pitch P2 of the screw thread 13a for screwing, or the outer diameter D1 of the reverse thread 13c is the outer diameter D2 of the screw thread 13a for screwing. It is smaller or both are combined. However, depending on the material of the wooden frame 3 and the opening 2, or the screwing conditions, the wood screw 11 of the present invention can be screwed in even if the screw thread for screwing and the screw thread in the opposite direction have the same pitch and outer diameter. Is possible.

状態である。When the tip of the inclined surface 12c of the head 12 reaches the surface of the wooden frame 3, the beveled blade 12e begins to scrape the wooden frame 3 to start digging. Then, the inclined surface 12 c enters the wooden frame 3 and the head 12 is buried in the wooden frame 3. When the top surface 12a approaches the surface of the wooden frame 3, the cutting blade 12d makes a hole through which the top surface 12a can enter. Therefore, the wood screw 11 of the present invention can be screwed in until it is flush with the wooden frame 3 without the recess 3c (FIGS. 7 and 8). And the wood screw 11 is
Finally, the wooden frame 3 is tightened so as to come into close contact with the opening 2. This state is the same as that described in the conventional example of FIG.

Not all 3b and the like are necessary, and one or two of these may be selectively adopted.

１１を逆方向に回して隙間６の間隔ｓを調整する。When all the wood screws at the four corners of the wooden frame 3 are tightened in this way, the distortion of the opening 2 is transferred to the wooden frame 3. Therefore, a level or the like is applied to the wooden frame 3, and the wooden screw 11 is turned in the opposite direction to adjust the space s of the gap 6 so that the wooden frame 3 becomes vertical, horizontal, or at a predetermined angle.

It will rotate in the tightening direction. Therefore, head 1
2 tries to enter the wooden frame 3, so that the head 12 has the wooden frame 3
Never stick out of. Therefore, the floating d shown in the conventional example does not occur, and the gap 6 can be accurately determined. Then, the clearance 6 is filled with an adhesive or the like to fix the wooden frame 3 to the opening 2.

In this embodiment, the slopes 13d and 1
3e is characterized in that the slope 13d on the tip side of the wood screw 11 is made gentler than the slope 13e on the head side so as to easily enter the wooden frame 3. This is the opposite thread 13c
It is intended to reduce the resistance force of No. 2 and can be used together with increasing the pitch or reducing the outer diameter as described above. Other configurations are the same as those of the embodiment shown in FIG.

That is, except for the head, the structure is the same as that of FIG. 1 or 3. This embodiment is characterized in that the inclined surface 12c of the head is a circular arc and the inclined blade 12e is not provided. The lower surface 12f of the cutting blade 12d is perpendicular to the shaft body 13. In this way, by making the lower surface 12f at a right angle to the shaft body, it is possible to reduce the wear of the die for molding the wood screw,
The life of the mold can be extended.

きる。According to the present invention as described above,
In a wood screw consisting of a shaft body having screw threads formed in a spiral shape on the outer peripheral surface and a head formed at one end of the shaft body, the screw threads are formed on the tip side of the shaft body. However, since a screw thread in the opposite direction to the screwing screw is formed on the head side of the shaft, and the screwing force of the screwing screw is made larger than the resistance force of the screw screw in the opposite direction,
If it is used when the wooden frame is attached to the opening of the wall, the gap between the wooden frame and the opening can be set in a stable state.

If it is provided or a slanting blade is provided on the inclined surface, it is not necessary to form a concave portion for accommodating the head of the wood screw in the wooden frame.
In addition, if a knurled blade is formed between the screw threads for screwing, screwing becomes easier.
