アンカ一本体１内にボルト３をねじ込み、そのボルト３
に袋ナツト４をねじ込んでアンカ一本体１の開口を覆っ
ておくものである。When constructing a house, the anchor body 1 is
Insert and secure it into the hole H of the wall W etc., as shown in Fig. 4.
Screw the bolt 3 into the anchor body 1, and
The opening of the anchor body 1 is covered by screwing a cap nut 4 into the anchor body 1.

居住者が室内装置品等を取付ける場合には、第４図の状
態からナツト４を外し、ボルト３を回して大径のねじ部
３１の手前側端部がアンカ一本体１の開口端部に来るま
で引き出し、取付けるべき物品の孔をボルト３の小径ね
じ部３．２に通して、上から袋ナツト４をねじ込む。When a resident wants to install indoor equipment, etc., remove the nut 4 from the state shown in FIG. Pull it out as far as it will go, pass the small diameter threaded portion 3.2 of the bolt 3 through the hole of the article to be attached, and screw in the cap nut 4 from above.

このとき、小径ねじ部３２の方が大径ねじ部３１よりも
摩擦力が小さいから、始めに袋ナツト４が小径ねじ部３
２にねじ込まれ、さらに回すと、大径ねじ部３１が本体
１内にねじ込まれて、袋ナツト４と本体１の端部又は壁
面との間に物品が締付固定される。At this time, since the small diameter threaded part 32 has a smaller frictional force than the large diameter threaded part 31, the cap nut 4 is first attached to the small diameter threaded part 31.
2, and when turned further, the large diameter threaded portion 31 is screwed into the main body 1, and the article is tightened and fixed between the cap nut 4 and the end or wall surface of the main body 1.

取り付ける物品は、小径ねじ部３２の長さに応じて、例
えば第５図示のフックＦ等の薄手のものから第６，７図
示の種々の厚さの板材ＰＩ、Ｐ２に至るまで各種の厚さ
の物品を取付けることができる。The articles to be attached may have various thicknesses depending on the length of the small-diameter screw portion 32, from thin objects such as the hook F shown in Figure 5 to plate materials PI and P2 of various thicknesses shown in Figures 6 and 7. items can be attached.

またボルト３を図のように大径ねじ部３１の両側に長さ

小径ねじ部３２ｂを手前にして取付けることができる。In addition, when the bolt 3 is formed with small diameter threaded parts 32 a and 32 b of different lengths on both sides of the large diameter threaded part 31 as shown in the figure, it is possible to use a relatively thin article such as a hook F or a thin plate material Pl. When installing, as shown in Figure 5.6, install with the shorter small diameter screw part 32a facing you, and when installing thick plate material P2 etc. as shown in Figure 7, install with the longer small diameter screw part 32b. It can be installed with the front facing you.

なお、例えば第８図に示すようにコンクリート壁Ｗの前
に防露壁Ｗａがある様な場合には、長尺のアンカ一本体
１′を用いる。For example, when there is a dew prevention wall Wa in front of a concrete wall W as shown in FIG. 8, a long anchor body 1' is used.

アンカ一本体１及びプラグ２は、図示例のように筒状ア
ンカ一本体１内にプラグ２を入れてプラグを打ち込むも
のに限らず、例えば筒状アンカ一本体の先端にプラグ２
を嵌めアンカ一本体を打ち込む形式のもの等適宜である
。The anchor body 1 and the plug 2 are not limited to the one in which the plug 2 is inserted into the cylindrical anchor body 1 and the plug is driven in as shown in the illustrated example. For example, the plug 2 is attached to the tip of the cylindrical anchor body 1.
An appropriate method is to fit the anchor and drive the anchor body into it.

本案アンカーは上記のようにボルト３とナツト４とを具
え、ボルト３はアンカ一本体１の雌ねじ１ａに螺合する
雄ねじ部３１とそれより小径の雄ねじ部３２とで形成さ
れているから、ボルト３のアンカ一本体１へのねじ込み
量が多くなってもトルクは一定で軽くねじ込むことがで
きる。The proposed anchor includes the bolt 3 and the nut 4 as described above, and the bolt 3 is formed of a male threaded portion 31 that screws into the female thread 1a of the anchor body 1 and a male threaded portion 32 with a smaller diameter. Even if the amount of screwing into the anchor body 1 of No. 3 increases, the torque remains constant and the screwing can be done lightly.

又アンカ一本体１内にねじ込んだボルトを回して引き出
しても、大径の雄ねじ部３１がアンカ一本体１内にある
ときは、その雄ねじ部３１と本体１の雌ねじ１ａとは充
分に係合しているもので、その確認が容易であり、その
係合が不足して取付けた物品が不用意に脱落するような
ことがない。Furthermore, even if the bolt screwed into the anchor body 1 is turned and pulled out, if the large diameter male threaded portion 31 is inside the anchor body 1, the male threaded portion 31 and the female thread 1a of the body 1 will fully engage. This makes it easy to check and prevents the attached item from accidentally falling off due to insufficient engagement.

またナツト４は袋ナツトであるから、ナツト４からボル
ト３の端部が突出して邪魔になったり、見苦しいといっ
たようなことがない。Further, since the nut 4 is a cap nut, the end of the bolt 3 does not protrude from the nut 4 and become a hindrance or unsightly.

るといった面倒がない。When not attaching an item to the anchor, screw the bolt 3 into the anchor body as shown in Figure 4.8, and cover the end opening of the anchor body with a cap nut 4 for a better appearance and to secure the bolt. There is no need to worry about storing 3/Natsu 4 in another location and losing it.
