考案の目的
（産業上の利用分野）
この考案は抜け止め作用を備えた釘に関するも
のである。[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to a nail with a locking action.
（従来の技術）
例えば、気泡コンクリートに打ち込まれる釘に
は抜け止め機能を付する必要がある。(Prior Art) For example, nails driven into aerated concrete need to be provided with a locking function.
（考案が解決しようとする問題点）
従来、この種の気泡コンクリート用釘では他の
者の介在により釘軸部の先端部を抜け止め用に拡
開しているため製作に手間がかかりコスト高を招
来していた。(Problem that the invention aims to solve) Conventionally, with this type of nail for aerated concrete, the tip of the nail shaft was expanded to prevent it from falling out through the intervention of another person, which was time-consuming and costly to manufacture. was inviting.
考案の構成
（問題点を解決するための手段）
前記問題点を解決するために、この考案におい
ては、釘軸部と頭部とよりなる釘において、前記
軸部にその長手方向へ割り溝を設けてその軸部を
二つ割にするとともに、全体を所定角度ねじり、
両割り片の先端にはそれぞれ前記割り溝方向へ後
退する斜面を形成した。Structure of the invention (means for solving the problem) In order to solve the above problem, in this invention, in a nail consisting of a nail shaft and a head, a split groove is formed in the shaft in the longitudinal direction of the nail. The shaft is divided into two parts, and the whole is twisted at a predetermined angle.
At the tips of both split pieces, slopes receding toward the split grooves were formed.
（作用）
従つて、気泡コンクリート等に打ち込まれると
斜面の作用及びねじりにより割片が拡開される。
又、打ち込まれた状態においてはねじり作用によ
り引抜耐力が大きい。(Function) Therefore, when poured into aerated concrete, etc., the split pieces are expanded due to the action of the slope and twisting.
Moreover, in the driven state, the pull-out strength is large due to the twisting action.
（実施例）
以下、この考案を具体化した一実施例を第１図
〜第４図に従つて説明する。(Embodiment) An embodiment embodying this invention will be described below with reference to FIGS. 1 to 4.
円板状の頭部１に連なる断面長四角形状の釘軸
部２には軸心に沿つて長手方向に延びる割り溝３
が設けられ、割り片２ａ，２ｂが形成されてい
る。釘軸部２は基端から先端にかけてその軸心を
中心にして90゜ねじられて螺旋状に形成されてい
る。釘軸部２先端には、前記両割り片２ａ，２ｂ
先端から割り溝３に向かつて後退し、両者で逆Ｖ
字状をなす斜面４ａ，４ｂが形成されている。 The nail shaft portion 2, which has an elongated rectangular cross section and is connected to the disc-shaped head 1, has a split groove 3 extending in the longitudinal direction along the axis.
is provided, and split pieces 2a and 2b are formed. The nail shaft portion 2 is twisted 90 degrees around its axis from the base end to the distal end to form a spiral shape. At the tip of the nail shaft portion 2, the two split pieces 2a, 2b are attached.
The tip moves toward the split groove 3 and retreats, creating an inverted V between the two.
Slopes 4a and 4b are formed in a letter shape.
さて、第４図に示すように本考案の釘を気泡コ
ンクリートに打ち込むと、各割り片２ａ，２ｂ
は、自身のねじれと先端の斜面４ａ，４ｂの楔作
用により、ねじれながら次第に拡開湾曲して気泡
コンクリートへと侵入する。 Now, as shown in Fig. 4, when the nail of the present invention is driven into aerated concrete, each split piece 2a, 2b
Due to its own torsion and the wedge action of the slopes 4a and 4b at the tips, it gradually expands and curves while twisting, and penetrates into the aerated concrete.
従つて、本考案の釘においては、抜け止めの機
能を有するだけでなく、各割り片がねじれて打ち
込まれるため、引き抜き耐力が増すという利点が
ある。 Therefore, the nail of the present invention not only has the function of preventing the nail from coming off, but also has the advantage of increasing the pull-out strength because each split piece is twisted and driven.
なお、この考案は前記実施例に限定されるもの
ではなく、例えば釘軸部を断面長四角形状でなく
他の多角形状にしたり、円形にしたり、各割り片
のねじれの角度を変更したりする等、この考案の
趣旨を逸脱しない範囲で各部の形状、構成等を任
意に変更することも可能である。 Note that this invention is not limited to the above embodiments; for example, the nail shaft may be made into a polygonal shape instead of a rectangular cross section, or may be made circular, or the angle of twist of each split piece may be changed. It is also possible to arbitrarily change the shape, structure, etc. of each part without departing from the spirit of this invention.
考案の効果
以上詳述したように、この考案の釘は打ち込む
ことにより、自身が拡開して抜け止めの作用をな
すだけでなく、引き抜き耐力が増加し、より確実
に釘着出来るという優れた効果を奏する。Effects of the invention As detailed above, when the nail of this invention is driven in, it not only expands itself to prevent it from falling out, but also has an excellent ability to increase the pull-out strength and ensure more secure nailing. be effective.
