る。2. Description of the Related Art Generally, a driving screw is often used to fix a gypsum board to a thin steel plate. The driving screw is composed of a large diameter portion and a small diameter portion. First, as shown in FIG. 5, at the time of driving, the small diameter portion penetrates the thin steel plate, and the large diameter portion is driven into the gypsum board,
At the next screwing, the large diameter part is screwed into the steel plate and fastened.

厚の石膏ボードを止めるものの方が長い。[0003] In addition to the case where one gypsum board is fixed to a thin steel plate, there are cases where two or more gypsum boards are fixed, and some gypsum boards are thick or thin. As a matter of course, the driving screws for fixing two sheets or the thick gypsum board are longer than the driving screws for fixing one gypsum board or the thin one.

ネジを使用することが求められている。In some cases, one gypsum board and two gypsum boards are attached at the same construction site, or thin and thick gypsum boards are fixed. Depending on the thickness of the gypsum board, the length may vary. The work efficiency is poor if different driving screws are used. For this reason, it is required to use the same driving screw.

るを得なかった。However, with the conventional one-shot driving screw, the shaft length is insufficient to fix two screws, resulting in poor fixing. On the other hand, if one gypsum board is to be fixed with two driving screws, there is a problem that a steel plate penetrates to a large diameter portion and a predetermined fastening force cannot be obtained. Therefore, the type of the driving screw had to be changed depending on the thickness and the number of gypsum boards.

ジ。In order to solve the above-mentioned problems, a driving screw according to the present invention has a helical screw portion formed substantially over the entire length of a shaft portion, and has an outer diameter including the screw portion on a head portion. A driving screw formed so as to be gradually reduced in at least three steps from a near side.

テーパー部４、５が形成されている。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral A denotes a driving screw, and the driving screw A is formed by forming a helical screw portion 2 over substantially the entire length of a shaft portion 1. The outer diameter including the screw portion 2 is a head. It is formed smaller in three stages in the order of upper, middle and lower from the part closer to the part 3. Further, tapered portions 4 and 5 are formed between the upper screw portion 2a and the middle screw portion 2b and between the middle screw portion 2b and the lower screw portion 2c to connect the screw portions 2a, 2b and 2c of the respective stages. Have been.

裂けたりすることがない。Next, the use of the driving screw A having the above structure will be described. First, when one gypsum board 6 is fastened to the thin steel plate 7 by a screw driving machine (not shown), FIG.
As shown in (a), the driving screw of the first stage stops through the thin steel plate 7 to the middle screw portion 2b of the driving screw A. Subsequently, the driving screw A is rotated by the second-stage screwing operation, and the upper screw portion 2a is screwed into the thin steel plate 7 as shown in FIG. Since the outer diameter of the upper screw portion 2a is larger than that of the middle screw portion 2b, the upper screw portion 2a is screwed strongly into the thin steel plate 7, and a strong fastening force is obtained. In addition, since the tapered portions 4 and 5 are formed between the upper threaded portion 2a and the middle threaded portion 2b and between the middle threaded portion 2b and the lower threaded portion 2c, the resistance is reduced. At the time of driving and the second-stage screwing are performed smoothly, and the through-hole 8 of the gypsum board 6 or the thin steel plate 7 does not become unnecessarily large or torn.

られる。Next, when the two gypsum boards 6a and 6b are polymerized and fastened to the thin steel plate 7, as shown in FIG. 3 (a), the driving depth of the first stage driving operation (the outer plaster Since the distance from the surface of the board 6a to the head 3 of the driving screw A) is almost the same as that of a single gypsum board 6, it stops through the thin steel plate 7 to the lower thread 2c of the driving screw A. . Next, the same figure is shown by the second stage screwing operation.
The driving screw A rotates as shown in FIG.
Is screwed into the thin steel plate 7. Since the outer diameter of the middle screw portion 2b is larger than that of the lower screw portion 2c, the middle screw portion 2b
Is strongly screwed into the thin steel plate 7, and a similarly strong fastening force is obtained.

できる。As described above, the outer diameter of the driving screw A is set to 3
Since it is formed differently at each stage, a single driving screw A can always obtain a sufficient fastening force corresponding to the gypsum boards 6, 6a, 6b having different thicknesses. Therefore, one gypsum board at the same construction site and 2
Since there is no need to perform a complicated operation of changing the type of the driving screw A in the case of a single sheet, the operation efficiency can be improved.

になるので、石膏ボードの押えがより強くなる。The outer diameter of the driving screw A is not limited to three steps, but may be formed so that the diameter varies stepwise over four or more steps. When one or two gypsum boards or gypsum boards are fastened by such a driving screw, a portion of the driving screw A having a different outer diameter will remain on the gypsum board itself even after screwing. Presser becomes stronger.

Also in this case, as shown in FIGS. 4 (a) and 4 (b), after the driving screw A is driven into the thin steel plate 7, the hole opened in the thin steel plate 7 when the screw is further screwed is large. When the screwing is completed, the driving screw A is screwed tightly to the thin steel plate 7.

る場合などにも適用することができる。Further, in the above-mentioned example, the gypsum board is fixed to the thin steel plate, but the present invention is not limited to this. For example, wood may be used instead of thin steel plate, and plywood, board material, etc. may be used in place of gypsum board to fix gypsum board to wood or plywood to thin steel plate. Can also be applied.
