Description

本発明は、コンクリート躯体に外壁材等を固定するためのアンカーピンの無音打ち込み方法及び装置に関するものである。 The present invention relates to a silent driving method and an apparatus for anchor pins for fixing an outer wall material or the like to a concrete skeleton.

この種アンカーピンの打ち込み装置には、従来から図４に示す方法（特許文献１）が知られている。 The method shown in FIG. 4 (Patent Document 1) has been conventionally known for this type of anchor pin driving device.

図４に示す方法は、モルタル外壁１１からコンクリート躯体１０に到達する打ち込み穴１３を開口し、肩面に鍔付きのアンカーピン１２を差し込み、内部の拡開プラグ１７に打ち込み棒１５を当接し、ハンマー１６で打ち込むことにより、割り溝１４を拡開して打ち込み穴１３に圧着する方法である。 In the method shown in FIG. 4, a driving hole 13 reaching the concrete skeleton 10 is opened from the mortar outer wall 11, an anchor pin 12 with a flange is inserted into the shoulder surface, and the driving rod 15 is brought into contact with the internal expansion plug 17. This is a method of expanding the split groove 14 and crimping it into the driving hole 13 by driving with a hammer 16.

この図４に示す方法は、ハンマー１６で拡開プラグ１７を打ち込むので、病院や学校などの静粛性が要求される工事現場では、騒音や振動が発生し、打撃によるアンカー取付け方法は不向きである。
この問題を解決するために、図５に示す特許文献２には、無音による方法が記載されている。この方法は、コンクリート躯体１０の打ち込み穴１３にアンカーピン１２を挿入し、このアンカーピン１２の内側の雌ねじ２１に、アンカー保持具１８の先端の雄ねじ２０を螺合し、このアンカー保持具１８を加圧手段１９に連結し、加圧手段１９の押圧ロッド２２で打ち込み棒１５をゆっくりと押し出すことで拡開プラグ１７を叩き込むことなく押し込み、この拡開プラグ１７でアンカーピン１２の先端部の割り溝１４を拡開し、打ち込み穴１３に圧着する方法である。 In the method shown in FIG. 4, since the expansion plug 17 is driven by the hammer 16, noise and vibration are generated at construction sites where quietness is required such as hospitals and schools, and the anchor mounting method by impact is not suitable. ..
In order to solve this problem, Patent Document 2 shown in FIG. 5 describes a silent method. In this method, the anchor pin 12 is inserted into the driving hole 13 of the concrete skeleton 10, and the male screw 20 at the tip of the anchor holder 18 is screwed into the female screw 21 inside the anchor pin 12, and the anchor holder 18 is inserted. It is connected to the pressurizing means 19, and the driving rod 15 is slowly pushed out by the pressing rod 22 of the pressurizing means 19 to push in the expansion plug 17 without hitting it, and the expansion plug 17 splits the tip of the anchor pin 12. This is a method of expanding the groove 14 and crimping it into the driving hole 13.

本発明によるアンカーピンの無音打ち込み方法及び装置の実施例１を図面に基づき説明する。
図１において、コンクリート躯体２５の壁面に、モルタル壁面材、タイル、網目材、その他の外壁材２６を張り付けるためにアンカーパイプ２８を打ち込むものとする。
外壁材２６側からコンクリート躯体２５に達する位置までドリルで下穴２７を穿設する。この下穴２７の開口部における外壁材２６の壁面には、凹溝４２を形成し、この凹溝４２にパッキン３０を介在して基端部の鍔部２９が面一となるようにアンカーパイプ２８を挿入する。このアンカーパイプ２８には、先端の軸方向と直交する方向の周囲に複数の凹凸部３１が内周側に突出して形成されるとともに、先端から途中まで複数本のすり割り３２が形成されている。また、アンカーパイプ２８の内部には、アンカーパイプ２８の内径よりわずかに小さな径の拡開プラグ３３が挿入され、この拡開プラグ３３の先端のテーパー部３４が前記凹凸部３１の内面に軽く接している。さらに、前記アンカーパイプ２８の基端部側内面には、雌ねじ部３５が形成されている。 The silent driving method of the anchor pin and the first embodiment of the apparatus according to the present invention will be described with reference to the drawings.
In FIG. 1, it is assumed that the anchor pipe 28 is driven into the wall surface of the concrete skeleton 25 in order to attach the mortar wall surface material, the tile, the mesh material, and the other outer wall material 26.
A pilot hole 27 is drilled from the outer wall material 26 side to a position reaching the concrete skeleton 25. A concave groove 42 is formed on the wall surface of the outer wall material 26 at the opening of the prepared hole 27, and an anchor pipe is provided so that the flange portion 29 at the base end is flush with the concave groove 42 with the packing 30 interposed therebetween. 28 is inserted. In the anchor pipe 28, a plurality of uneven portions 31 are formed so as to project toward the inner peripheral side around a direction orthogonal to the axial direction of the tip, and a plurality of grinds 32 are formed from the tip to the middle. .. Further, an expansion plug 33 having a diameter slightly smaller than the inner diameter of the anchor pipe 28 is inserted into the anchor pipe 28, and the tapered portion 34 at the tip of the expansion plug 33 lightly contacts the inner surface of the uneven portion 31. ing. Further, a female threaded portion 35 is formed on the inner surface of the anchor pipe 28 on the base end side.

押し込み棒３６は、先端が前記アンカーパイプ２８より径の小さな先端ロッド３７と、前記雌ねじ部３５に螺合する雄ねじ部３８と、この雄ねじ部３８に位置調整可能な位置決めリング３９と、基端部の回転装置４１に固着される多角形などの挟着部４０とからなる。
前記雌ねじ部３５と雄ねじ部３８は、拡開プラグ３３の打ち込み直前（図１の状態）に十分に押し込み負荷を支持できるように螺合し、また、拡開プラグ３３の打ち込み後（図２の状態）でも螺合し、かつ、位置決めリング３９が雄ねじ部３８から外れないような長さとする。 The push rod 36 includes a tip rod 37 whose tip has a diameter smaller than that of the anchor pipe 28, a male threaded portion 38 screwed into the female threaded portion 35, a positioning ring 39 whose position can be adjusted on the male threaded portion 38, and a base end portion. It is composed of a sandwiching portion 40 such as a polygon fixed to the rotating device 41 of the above.
The female screw portion 35 and the male screw portion 38 are screwed so as to sufficiently support the pushing load immediately before the expansion plug 33 is driven (the state shown in FIG. 1), and after the expansion plug 33 is driven (FIG. 2). The length is set so that the positioning ring 39 does not come off from the male threaded portion 38 even in the state).

このような構成において、図１に示すように、下穴２７に拡開プラグ３３を有するアンカーパイプ２８を挿入する。外壁材２６に凹溝４２があるときは、パッキン３０を介して鍔部２９を嵌め込み、凹溝４２がないときは、外壁材２６の表面に接するようにして取り付ける。
つぎに、押し込み棒３６の雄ねじ部３８部分をアンカーパイプ２８の雌ねじ部３５にねじ込み、拡開プラグ３３の端面に先端ロッド３７の先端を軽く当接するまでねじ込む。この状態で、位置決めリング３９から鍔部２９までの距離ｄ１を、拡開プラグ３３を圧入して凹凸部３１におけるすり割り３２を拡開して下穴２７の内壁に密着固定する位置ｄ２と一致するように調整する。 In such a configuration, as shown in FIG. 1, an anchor pipe 28 having an expansion plug 33 is inserted into the prepared hole 27. When the outer wall material 26 has a concave groove 42, the flange portion 29 is fitted via the packing 30, and when there is no concave groove 42, the outer wall material 26 is attached so as to be in contact with the surface of the outer wall material 26.
Next, the male threaded portion 38 portion of the push rod 36 is screwed into the female threaded portion 35 of the anchor pipe 28, and is screwed in until the tip of the tip rod 37 lightly abuts on the end face of the expansion plug 33. In this state, the distance d1 from the positioning ring 39 to the flange portion 29 coincides with the position d2 in which the expansion plug 33 is press-fitted to expand the slit 32 in the uneven portion 31 and firmly fix it to the inner wall of the prepared hole 27. Adjust to do.

位置決めリング３９の位置を調整したら、押し込み棒３６の挟着部４０を回転装置４１のチャックに固定して回転装置４１をアンカーパイプ２８側に押し付けながら押し込み棒３６を回転する。この押しつけは、雌ねじ部３５と雄ねじ部３８が螺合している状態で、アンカーパイプ２８が押し込み棒３６と一緒に共回りしない程度の抵抗をつけるために外壁材２６の凹溝４２又は表面にパッキン３０と鍔部２９とを密接させる。
アンカーパイプ２８が押し込み棒３６と一緒に共回りしない程度に外壁材２６の凹溝４２又は表面の接触部分に抵抗を与えつつ押し込み棒３６を回転させると、押し込み棒３６が進出して拡開プラグ３３を押し出す。位置決めリング３９が鍔部２９に当接するまで押し込むと、拡開プラグ３３が凹凸部３１の適正位置まで達し、凹凸部３１におけるすり割り３２を拡開して下穴２７の内壁に密着固定する。 After adjusting the position of the positioning ring 39, the sandwiching portion 40 of the push rod 36 is fixed to the chuck of the rotating device 41, and the pushing rod 36 is rotated while pressing the rotating device 41 against the anchor pipe 28 side. This pressing is performed on the concave groove 42 or the surface of the outer wall material 26 in order to provide resistance so that the anchor pipe 28 does not rotate together with the pushing rod 36 while the female threaded portion 35 and the male threaded portion 38 are screwed together. The packing 30 and the flange portion 29 are brought into close contact with each other.
When the push rod 36 is rotated while giving resistance to the concave groove 42 of the outer wall material 26 or the contact portion on the surface to the extent that the anchor pipe 28 does not rotate together with the push rod 36, the push rod 36 advances and the expansion plug is expanded. Push out 33. When the positioning ring 39 is pushed in until it comes into contact with the flange portion 29, the expansion plug 33 reaches the appropriate position of the uneven portion 31, and the slit 32 in the uneven portion 31 is expanded and firmly fixed to the inner wall of the prepared hole 27.

拡開プラグ３３の打ち込みが終了したら回転装置４１を逆回転して押し込み棒３６のみを外壁材２６のから抜き去る。このとき、アンカーパイプ２８は、下穴２７に固着されているので、押し込み棒３６は、容易に逆回転して抜き去ることができる。 When the driving of the expansion plug 33 is completed, the rotating device 41 is rotated in the reverse direction to remove only the pushing rod 36 from the outer wall material 26. At this time, since the anchor pipe 28 is fixed to the prepared hole 27, the push rod 36 can be easily rotated in the reverse direction and removed.

前記実施例では、押し込み棒３６とアンカーパイプ２８が一緒に共回りするのを防止するため、鍔部２９と凹溝４２の間にパッキン３０を介在したが、これに限られるものではない。
図３（ａ）に示すように、鍔部２９の裏面に凸部４３を形成し、凹溝４２の表面の外壁材２６（外壁材２６がないときはコンクリート躯体２５の表面）に、凹部４４を形成するようにしてもよい。また、鍔部２９の裏面の凸部４３が凹溝４２又は表面に食いつきがよければ凹部４４は省いてもよい。 In the above embodiment, the packing 30 is interposed between the flange portion 29 and the concave groove 42 in order to prevent the push rod 36 and the anchor pipe 28 from rotating together, but the present invention is not limited to this.
As shown in FIG. 3A, a convex portion 43 is formed on the back surface of the flange portion 29, and the concave portion 44 is formed in the outer wall material 26 (the surface of the concrete skeleton 25 when there is no outer wall material 26) on the surface of the concave groove 42. May be formed. Further, if the convex portion 43 on the back surface of the flange portion 29 has a good bite to the concave groove 42 or the front surface, the concave portion 44 may be omitted.

前記凸部４３は、図３（ｂ）に示すように、鍔部２９の裏面からアンカーパイプ２８の外周面に軸方向に伸びた複数個の突条とし、前記下穴２７に一緒に共回りしないように圧入するようにしてもよい。 As shown in FIG. 3B, the convex portion 43 is formed into a plurality of ridges extending in the axial direction from the back surface of the flange portion 29 to the outer peripheral surface of the anchor pipe 28, and is co-rotated with the prepared hole 27. It may be press-fitted so as not to.
