【考案の詳細な説明】
＜産業上の利用分野＞
本考案は、部材取付のためのコンクリート用埋
込み金具いわゆるインサートの改良に関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of a so-called insert, which is a concrete embedding fitting for attaching a member.
＜従来の技術＞
インサート１の一種として、第２図に示すよう
に部材取付用のボルト孔（図示せず）を長さ方向
に穿設した軸部２の下端にフランジ３を設ける。
フランジ３は底面が平らで上方がすぼむ円錐状に
形成したものがある。<Prior Art> As a type of insert 1, as shown in FIG. 2, a flange 3 is provided at the lower end of a shaft portion 2 in which bolt holes (not shown) for attaching members are bored in the length direction.
The flange 3 has a conical shape with a flat bottom and a concave top.
＜解決すべき問題点＞
しかし、このインサート１では埋設状態でボル
トに強い引き抜き外力を加えると、フランジ３は
底面が平らで、これを下から支えるものがないた
め、フランジ３が下方へ垂れて、インサート１が
コンクリート内から引き抜かれる虞れがある。<Problems to be Solved> However, with this insert 1, if a strong external pulling force is applied to the bolt while it is buried, the flange 3 will sag downward because the bottom surface of the flange 3 is flat and there is nothing to support it from below. , there is a risk that the insert 1 will be pulled out from within the concrete.
＜解決するための手段＞
本考案は、この欠点を解決するためフランジを
改良することにより、容易には引き抜かれないイ
ンサートを提供しようとするもので、つぎのよう
に構成する。<Means for Solving> In order to solve this problem, the present invention attempts to provide an insert that cannot be easily pulled out by improving the flange, and is configured as follows.
軸部の長さ方向に部材取付用のボルト孔を穿設
し、軸部の下部に上面が広く埋設側となる下方が
すぼむ逆円錐台状のフランジを全周にわたつて設
け、フランジの斜面に複数のフインを設けてなる
インサート。 Bolt holes for attaching components are drilled in the length direction of the shaft, and an inverted truncated conical flange with a wide upper surface and a concave bottom facing the buried side is provided at the bottom of the shaft all around the flange. An insert with multiple fins on the slope.
＜作用＞
このようにフランジを下方がすぼむ逆円錐状と
すると共に、フランジの斜面に複数の膨出部を設
けて補強した。このため、インサートを引き抜こ

下方へたれてない。<Function> In this way, the flange was formed into an inverted conical shape concave at the bottom, and a plurality of bulges were provided on the slope of the flange to reinforce it. Therefore, even if a large external force is applied to pull out the insert, the outer shape of the flange provides a large resistance to the external force, and since the wide upper surface of the flange is supported from below by multiple fins, The flange does not hang downward easily.

A flange 13 is provided at the bottom of 2. Flange 13
Contrary to the conventional product shown in Fig. 2, the shape is an inverted truncated cone with a wide upper surface and a concave lower part on the buried side, and fins 14 are provided at three locations on the slope so that the flange 13 can be inserted from below. support. Flange 13 of shaft portion 12
A thick portion 15 is provided at the root connected to. Thick part 1
For example, in the insert 11 in which the inner diameter of the shaft portion 12 is 12 mm, the thickness of the thick portion 15 is approximately 1 mm thicker than the shaft portion 12. Protrusion 1 under flange 13
6 is provided, and a bolt hole 18 is provided in the length direction of the shaft portion 12 into which a bolt 17 for attaching the member is screwed. A screw 19 is carved into the inner surface of the bolt hole 18.
使用方法は、従来品と全く同様故省略する。 The usage method is exactly the same as the conventional product, so the explanation will be omitted.

ことはない。<Effects of the invention> As explained above, the present invention has a flange in the shape of an inverted truncated cone that is wider at the upper surface and constricts at the bottom, which is the buried side, at the lower part of the shaft, and also has a flange on the slope of the flange. had multiple fins to support the top from below. Therefore, even if a large external force is applied to pull out the insert, the outer shape of the flange provides a large resistance to the external pulling force, making it difficult to pull out. In addition, since the top surface of the flange is supported from below by multiple fins,
The flange does not easily sag downward and reduce its resistance.
