角よりも大きく形成したところにある。The present invention has been made in view of the above circumstances, and its specific means is to provide a columnar base body having a tapered portion at the tip and engraved with a groove of a predetermined shape, and a base end of the columnar base body. In a screw nail formed of a large-diameter head body integrally formed, a spiral thread groove different from the groove of the predetermined shape is screwed on the outer circumference of the columnar base body in the axial cross-sectional shape so as to be screwed with the female screw portion. The angle between the flank on the large-diameter head side and the axis-perpendicular line is larger than the angle between the flank on the tapered portion and the axis-perpendicular line.
更に、前記ねじ溝の含軸断面形状は、大径頭体側のフラ

尚、このスクリュー釘の大径頭体に工具が係合される係
合部を形成しておけば、工具を用いて当該スクリュー釘
を構築部材にねじ込むことが可能となる。According to the above-mentioned means, since the screw nail is formed on the outer peripheral surface of the columnar base of the screw nail in addition to the groove having the predetermined shape, when the two kinds of building members are coupled, the screw nail is divided into two kinds. When a nut is inserted into the building member so that the nut penetrates in such a state from the tip side of the columnar base and the female screw portion of the nut is screwed into the screw groove, a groove of a predetermined shape formed in the screw nail is formed. The screw nail can be prevented from idling and can be tightened, and the two kinds of building members are fastened with a sufficient coupling force in a state of being interposed between the large-diameter head body of the screw nail and the nut.
If a large-diameter head of the screw nail is formed with an engaging portion with which the tool is engaged, the screw nail can be screwed into the building member using the tool.

的に防止される。従って、このスクリュー釘を、上述の
ナットや工具を用いることなく単に金槌等で打ち込んで
おくだけでも、十分な結合力が得られることになる。In addition, the shaft groove cross-sectional shape of the thread groove is set so that the angle formed by the flank on the large-diameter head side and the axis perpendicular line is larger than the angle formed by the flank on the tapered portion side and the axis perpendicular line. Therefore, when driving the screw nail into the building member, the flank on the large-diameter head side does not have a large resistance in the driving direction, which enables smooth driving work, and at the same time, the screw nail can be driven. After being driven into the building member, the flank on the side of the tapered portion has a large resistance in the pulling direction, and the screw nail is effectively prevented from being pulled out. Therefore, a sufficient joining force can be obtained by merely driving the screw nail with a hammer or the like without using the above-mentioned nut or tool.

果的に防止されることになる。Furthermore, if the cross section of the thread groove containing the shaft is such that the intersection of the large-diameter head-side flank and the tapered portion-side flank has a curved shape, the screw nail can be attached using a hammer or the like. Even if a buckling load is applied during driving, a situation such as cracks will not occur at the intersection of this curved shape,
This effectively prevents breakage of the screw nail during driving.
以下、この考案の実施例を図面に基づいて説明する。 An embodiment of the present invention will be described below with reference to the drawings.
先ず、この考案の第１実施例を第１図乃至第３図に従っ

Is the tapered portion 2 at the tip (lower end) as in the above-mentioned conventional example.
Columnar substrate 4 having grooves 3 ...
And a large-diameter head body 5 integrally formed at the base end (upper end) of the columnar base 4. On the outer periphery of the columnar base 4, a single thread groove 6 with which a female thread portion is screwed is formed, and the axial cross-sectional shape of this thread groove 6 is as shown in FIG. That is, the angle α between the flank 7 on the large-diameter head side and the axis-perpendicular line X in the thread groove 6 is set to be larger than the angle β between the flank 8 on the tapered portion side and the axis-perpendicular line X. In other words, the flank 7 on the large-diameter head side, which has a resistance to the driving direction at the time of driving, has a larger gradient than the flank 8 on the tapered portion side, which has a resistance to the pulling direction after driving. And
The large-diameter head side flank 7 and the tapered side flank 8
The intersection 9 with and has a curved shape.

ト12としては市販のものを使用できることになる。That is, as shown in FIG. 3, one construction member 10 made of a lightweight concrete panel or the like has the other construction member 11 superposed, and the screw nail 1 is driven into both construction members 10 and 11 to penetrate them. Together with this, when the nut 12 is inserted from the tapered portion 2 side of the screw nail 1 in such a state and the female screw portion of the nut 12 is screwed into the thread groove 6 on the outer periphery of the columnar base 4, the screw nail 1 is formed. The grooves 3 ... 3 having a predetermined shape prevent the screw nail 1 from idling and can be tightened. In this way, the both construction members 10 and 11 are the large-diameter head body 5 of the screw nail 1 and the nut 1.
It will be fastened in a state of being interposed between the two and 2, and a much larger binding force will be obtained than in the case where the screw nail 1 is simply driven over both the construction members 10 and 11. If the thread groove 6 is formed so as to correspond to a metric screw or a unified screw, a commercially available nut 12 can be used.

ー釘１は容易に抜脱しなくなる。Moreover, since the screw groove 6 formed in the screw nail 1 has a shape as shown in FIG. 2, when the screw nail 1 is driven into a building member using a hammer or the like, a large diameter head is used. While the flank 7 on the body side does not have a great resistance, the flank 8 on the tapered portion side has a great resistance to the pulling-out direction after the screw nail 1 is driven into the building member. Therefore, the driving operation of the screw nail 1 is performed smoothly and smoothly, and after the driving operation, the screw nail 1 cannot be easily pulled out without using the nut as described above.
