Description

本発明はコンクリート等からなる既存の床や壁面に対して誰でも簡単に、且つ短時間に構造物を固定でき、大きな引っ張り強度を得る事のできるアンカーボルトに関する。The present invention relates to an anchor bolt that can easily fix a structure to an existing floor or wall made of concrete or the like in a short time and can obtain a large tensile strength.

既存のコンクリートにアンカーボルトを後付けする場合、所定の位置にドリルで穴を開け穴にアンカーボルトを挿入し、ボルトを回すとアンカーボルトの一端寄り部にあるナットの拡開テーパー面に固定用スリーブが乗り上がって固定用スリーブの外径を拡開することによりスリーブをコンクリート面に密着させて固定するようにしたものが知られている。When retrofitting anchor bolts to existing concrete, drill a hole in place and insert the anchor bolt into the hole. When the bolt is turned, the fixing sleeve is attached to the expanded taper surface of the nut near the one end of the anchor bolt. It has been known that the sleeve is fixed to the concrete surface by expanding the outer diameter of the fixing sleeve upon getting on.

又、固定用スリーブを同径の打ち込みスリーブで打込んで拡開テーパー面側の部分を押し広げて植設用ボルトを直接固定させるものも知られている。Further, it is also known that a fixing sleeve is driven by a driving sleeve having the same diameter, and a portion on the side of the expansion taper surface is pushed and widened to directly fix the planting bolt.

上記に述べたように一端寄り部にあるスリーブが下向きに拡開するタイプはコンクリート下穴の壁にスリーブを密着して引っ張り強度を得ているので打ち込んだ以上の大きな引っ張る力が働くとアンカーボルトが滑り抜けてしまうため、設置した構造物の安全性に支障がでることもある。
以上の問題点を解決するために、構造物を簡単な操作で手早く確実に固定でき、且つ引っ張り強度が強いアンカーボルトを提供することを課題とする。As described above, the sleeve with the one end closer to the end expands downward, and the sleeve is in close contact with the wall of the concrete pilot hole to obtain the tensile strength. May slip through and may interfere with the safety of the installed structure.
In order to solve the above problems, an object of the present invention is to provide an anchor bolt that can quickly and surely fix a structure with a simple operation and has high tensile strength.

上記の目的を達成するために本発明のアンカーボルトは図１に示すように、ワッシャー３、拡開テーパー面を形成したカラー４、端側にボルト部材である雄螺子２を形成し、一端寄り部に形成された拡開テーパー面で径が拡大される上部拡開形移動用スリーブ５からなり，部材を鉄または鉄合金で形成し、上部拡開形移動用スリーブ５の拡開部分に４つの拡開用スリット６を設けたことを特徴とするものであり、図中符号１はアンカーボルトを全体的に示す。In order to achieve the above object, as shown in FIG. 1, the anchor bolt of the present invention is formed with a washer 3, a collar 4 having an enlarged taper surface, and a male screw 2 as a bolt member on the end side. The upper expanding type moving sleeve 5 whose diameter is enlarged by the expanding taper surface formed in the portion, the member is made of iron or an iron alloy, and the upper expanding type moving sleeve 5 has 4 Two expansion slits 6 are provided, and reference numeral 1 in the drawing denotes an anchor bolt as a whole.

本発明にかかるアンカーボルトの実施の形態を図面に基づいて説明する。
図１アンカーボルトを組み立てた状態の正面図、図２はアンカーボルトの分解図、図３はアンカーボルトの施工状態を示す断面図、図４はアンカーボルトの施工順序を示す模式図で、同記図中符号１はアンカーボルトを全体的に示す。An embodiment of an anchor bolt according to the present invention will be described with reference to the drawings.
Fig. 1 is a front view of the assembled anchor bolt, Fig. 2 is an exploded view of the anchor bolt, Fig. 3 is a sectional view showing the construction state of the anchor bolt, and Fig. 4 is a schematic diagram showing the construction sequence of the anchor bolt. Reference numeral 1 in the figure indicates an anchor bolt as a whole.

アンカーボルト１は、拡開用テーパー面を形成したカラー４と、該拡開用テーパー面を形成したカラー４に外嵌させた上部拡開形移動用スリーブ５を備えてある。The anchor bolt 1 is provided with a collar 4 having a taper surface for expansion and an upper expansion type moving sleeve 5 externally fitted to the collar 4 having the taper surface for expansion.

上記の上部拡開形移動用スリーブ５は、拡開用テーパー面を形成したカラー４に外嵌する内径を有する筒状に形成され、拡開テーパー面を形成したカラー４側の筒部分には拡開を容易にするためのスリット６を４本刻設してあり、雄螺子２の端部にはワッシャー３が形成されている。The upper expanding type moving sleeve 5 is formed in a cylindrical shape having an inner diameter that is fitted around the collar 4 having the expanding taper surface, and the cylindrical portion on the collar 4 side having the expanding taper surface is formed on the cylinder portion on the collar 4 side. Four slits 6 are provided for easy expansion, and a washer 3 is formed at the end of the male screw 2.

拡開用テーパー面を形成したカラー４は部品製作上、作りやすいように分割でもよいとする。
尚、本発明アンカーボルトの実施の形態では部材を鉄または鉄合金で形成するようにしてあるが、鉄または鉄合金に代えて加工が可能であれば材質は拘らないとする。It is assumed that the collar 4 formed with the taper surface for expansion may be divided so that it can be easily produced in manufacturing the part.
In the embodiment of the anchor bolt of the present invention, the member is formed of iron or an iron alloy. However, the material is not limited as long as it can be processed instead of iron or an iron alloy.

［０００７］から［０００９］に記載した様に形成されたアンカーボルト１を使用する手順を［図４−１］、［図４−２］、［図４−３］にて説明する。
例えばコンクリート床面７にドリル等で植設用孔９を穿設後、当該植設用孔９にアンカーボルト１を挿入する。The procedure for using the anchor bolt 1 formed as described in [0007] to [0009] will be described with reference to [FIGS. 4-1], [4-2], and [FIG. 4-3].
For example, after drilling the planting hole 9 in the concrete floor surface 7 with a drill or the like, the anchor bolt 1 is inserted into the planting hole 9.

然る後、雄螺子２を締め込むと、雄螺子２の緊締力で上部拡開形移動用スリーブ５が図３に示すように拡開用テーパー面を形成したカラー４に上部拡開形移動用スリーブ５が乗り上がって上部拡開形移動用スリーブ５に形成したスリット部分６が外方に開かれて植設用孔９の内周面にスリット部分６が座屈して食い込む形で固定される。Thereafter, when the male screw 2 is tightened, the upper expanding type moving sleeve 5 is moved to the collar 4 having the expanding taper surface as shown in FIG. 3 by the tightening force of the male screw 2. The slit portion 6 formed on the upper expanding type moving sleeve 5 is opened outward and the slit portion 6 buckles and bites into the inner peripheral surface of the planting hole 9. The

発明の効果The invention's effect

上記の本発明アンカーボルトの最大の利点は、雄螺子２を締め込み上部拡開形移動用スリーブ５が上がり拡開する機能で、上部拡開形移動用スリーブ５にあるスリット部分６がコンクリートに密着ではなく座屈して食い込む形で固定ができ強い引っ張り強度を得られる。
また、コンクリートに密着ではなく座屈して食い込む形で固定できるので引っ張る力がかかると更にコンクリートに食い込み、より強い引っ張り強度を期待できる。The greatest advantage of the anchor bolt of the present invention described above is the function of tightening the male screw 2 and the upper expanding type moving sleeve 5 rising and expanding, and the slit portion 6 in the upper expanding type moving sleeve 5 is made of concrete. It can be fixed in the form of buckling and biting instead of being in close contact, and strong tensile strength can be obtained.
In addition, since it can be fixed by buckling and biting into the concrete, if it is pulled, it will further bite into the concrete and a higher tensile strength can be expected.

ドリルで穿孔された植設用孔９にアンカーボルト１を挿入し、雄螺子２を利用して締め込み上部拡開形移動用スリーブ５を拡開させることにより、アンカーボルトを打ち込む手間や特殊な工具や接着剤などを用いることなく、誰でも簡単に施工できるので、植設操作を少なくでき作業能率を大幅に向上させる利点がある。The anchor bolt 1 is inserted into the planting hole 9 drilled with a drill, and the male screw 2 is used to tighten the upper expanding type moving sleeve 5 so as to expand the anchor bolt. Since anyone can easily perform construction without using tools or adhesives, there is an advantage that the planting operation can be reduced and the work efficiency can be greatly improved.

又、雄螺子２を締め込む事で上部拡開形移動用スリーブ５を拡開させ、アンカーボルト１を直接固定するようにしてあるので、今迄のような固定用スリーブを同径の打ち込みスリーブで打込んで拡開テーパー面側の部分を押し広げて植設用ボルトを直接固定する場合のように大きな衝撃を与えることはないから、例えば発泡コンクリートのように脆いものにも使用することができ、その用途も幅広いものにすることができると言う利点もある。Further, the upper expansion type moving sleeve 5 is expanded by tightening the male screw 2, and the anchor bolt 1 is directly fixed. Therefore, the fixing sleeve as described above is a driving sleeve having the same diameter. It can be used for brittle materials such as foamed concrete. There is also an advantage that it can be used for a wide range of purposes.
