ある。In response to such a request, Japanese Patent Publication No. Hei 7-919
No. 23 proposes a mounting method shown in FIGS. According to this, when fixing the wooden frame 3 to the opening 2 formed in the wall, a wood screw 4 as shown in FIG. 6 is used. The wood screw 4 is formed by forming a helical thread 4b for screwing on the tip side of a shaft 4a, and forming a plurality of flange-shaped thin rings 4d on the head 4c side of the shaft 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 comprises an inner wooden frame body 3a and a frame-like plywood portion 3b surrounding the main body. Then, a recess 3c is formed at a position near the corner inside the vertical bar 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 wooden frame body 3a and the plywood part 3b, 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 ring 4d provides resistance to screwing, but the screwing force of the screw thread 4b overcomes and the thin ring 4d advances so as to bite into the wooden frame 3, as shown in FIG. The wooden frame 3 is screwed into the opening 2 until it comes into 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 located at four positions as shown in FIG. 5, all the wood screws 4 are connected to the wooden frame 3 as shown in FIG.
When the wooden frame 3 is tightened so as to be in close contact with the opening 2, the wooden frame 3 is distorted similarly to the opening 2.

At the position where the wooden frame 3 is vertical, stop the rotation of the wood screw 4 and
When the adhesive or the like is filled in the gap 6 between the opening and the opening 2, the wooden frame 3 can be completely fixed to the opening 2.

At this time, the thin ring 4d tries to move the wooden frame 3 together to the right side in FIG. However, the bonding force between the thin ring 4d and the wooden frame 3 is weak, and the wooden frame 3 does not move, and the head 4c of the wood screw 4 floats by d as shown in FIG. For this reason, even if the interval s of the gap 6 is accurately set, the floating d of the head 4c is in an unstable state, which causes 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 concave 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 knurling blade 13b cuts the surrounding wood, the wood screw 11 can be screwed in with a small torque. It can be easily screwed. Eventually, the tip of the wood screw 11 passes through the wooden frame 3.

となる。The tip of the penetrating wood screw 11 continues to be screwed into the opening 2 of the wall 1. Thereafter, the tip of the screw 13 c in the opposite direction reaches the surface of the wooden frame 3. For the thread 13c in the opposite direction, the screwing direction of the screwing thread 13a is a loosening direction, and the screwing thread 13a is resistant to screwing.

ねじ込むことが可能である。However, in the present invention, the thread 13 having the opposite direction is used.
The resistance force of c is made smaller than the screwing force of the screw thread 13a. Specifically, the pitch P1 of the thread 13c in the opposite direction is made larger than the pitch P2 of the thread 13a for screwing, or the outer diameter D1 of the thread 13c in the opposite direction is changed to the outer diameter D2 of the thread 13a for screwing. They are smaller or a combination of both. However, depending on the material of the wooden frame 3 and the opening 2 or the conditions of the screwing, the wood screw 11 of the present invention may be screwed in even if the pitch and the outer diameter of the screwing screw thread and the opposite screw thread are the same. 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 inclined blade 12e starts to cut the wooden frame 3 and starts 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, even without the concave portion 3c (FIGS. 7 and 8), the wood screw 11 of the present invention can be screwed in until it is flush with the wooden frame 3. And the wood screw 11
Finally, the wooden frame 3 is tightened so as to be in close contact with the opening 2. This state is similar to the state described in the conventional example of FIG.

11を逆方向に回して隙間6の間隔sを調整する。When the four wood screws of 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. Then, 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 interval s of the gap 6 so that the wooden frame 3 is vertical, horizontal, or at a predetermined angle.

Therefore, since the head 12 tries to enter the wooden frame 3, the head 12 never protrudes from the wooden frame 3. Therefore, the floating d shown in the conventional example does not occur, and the gap 6 can be accurately determined. Thereafter, the gap 6 is filled with an adhesive or the like, and the wooden frame 3 is fixed to the opening 2.

A shaft, and a head formed at one end of the shaft;
A tree that adjusts the distance between the opening and the wooden frame attached to the opening
In a frame adjusting wood screw, the wood
A screw thread for screwing into the opening through the frame, and a screw thread opposite to the screw thread for screwing with the wooden frame are formed on the head side of the shaft body. By making the outer diameter of the screw thread in the opposite direction smaller than the outer diameter of the screw thread for screwing, and making the slope on the tip end side of the shaft of the opposite screw thread gentler than the slope on the head side, since the screwing force of the screw threads and greater than the resistance force of the thread of the opposite, when mounting the wooden frame in the opening of the wall, wood
The gap between the frame and the opening can be set in a stable state.
