It has a pre-assembled configuration relative to the cap nut 2.

次に、この実施例の作用・効果を説明する。   Next, the operation and effect of this embodiment will be described.

まず、この実施例の足場用壁つなぎ取付ボルトの取り付け作業を、図４、５の取り付け作業工程図に基づいて説明する。   First, the mounting operation of the scaffolding wall connecting mounting bolts of this embodiment will be described based on the mounting operation process diagrams of FIGS.

まず、図４（イ）に示すように、ドリルビス１を鋼板等の取付壁面Ｐに対し直交する状態に先端ドリル１３を当接させた状態で、このドリルビス１における丸さら頭部の係合部１１にプラスドライバー５を係合させる。   First, as shown in FIG. 4 (a), with the drill screw 1 in contact with the tip drill 13 in a state orthogonal to the mounting wall surface P such as a steel plate, the engaging portion of the round head in this drill screw 1 11 is engaged with the Phillips screwdriver 5.

次に、このプラスドライバー５の軸線をドリルビス１の軸線に合わせた状態で、ドリルビス１を回転駆動させることにより、図４（ロ）に示すように、先端ドリル１３が取付壁面Ｐを穿孔し、タップ兼用雄ねじ部１４が穿孔後の孔７にねじ立てしながらねじ込まれていく。   Next, by rotating the drill screw 1 in a state where the axis of the plus screwdriver 5 is aligned with the axis of the drill screw 1, the tip drill 13 drills the mounting wall surface P as shown in FIG. The male screw portion 14 serving as a tap is screwed into the hole 7 after being drilled while being tapped.

そして、図４（ハ）に示すように、弾性クッション４が取付壁面Ｐに当接するまでタップ兼用雄ねじ部１４がねじ込まれた後は、ドリルビス１の丸さら頭部１２が袋ナット２の雌ねじ部２１内に入り込みながらねじ込まれて行き、図４（ニ）に示すように、丸さら頭部１２が弾性セットリング３を押し潰して貫通孔２２の内側開口縁部に圧接し、弾性クッション４が袋ナット２の係止壁２３外面と取付壁面Ｐとの間に挟持されて少し潰された状態で、取付壁面Ｐに対する足場用壁つなぎ取付ボルトの取り付けが完了する。   Then, as shown in FIG. 4 (c), after the tap-and-thread male screw portion 14 is screwed in until the elastic cushion 4 contacts the mounting wall surface P, the round head portion 12 of the drill screw 1 becomes the female screw portion of the cap nut 2. As shown in FIG. 4 (d), the round head portion 12 crushes the elastic set ring 3 and presses against the inner opening edge of the through hole 22, so that the elastic cushion 4 The attachment of the scaffolding wall connecting attachment bolt to the attachment wall surface P is completed in a state of being pinched between the outer surface of the locking wall 23 of the cap nut 2 and the attachment wall surface P and being slightly crushed.

次に、図５に示すように、袋ナット２の雌ねじ部２１に足場用壁つなぎ６の雄ねじ部６１を十分にねじ込んで螺着させることにより、図示を省略した仮設足場と取付壁面Ｐが強固につながれた状態になる。   Next, as shown in FIG. 5, the male thread portion 61 of the scaffold wall tether 6 is fully screwed into the female thread portion 21 of the cap nut 2 and screwed to secure the temporary scaffold and the mounting wall surface P (not shown). It becomes the state connected to.

なお、袋ナット２の雌ねじ部２１に足場用壁つなぎ６の雄ねじ部６１を螺着させる際に、足場用壁つなぎ６の軸線がドリルビス１の軸線とのズレがあった場合でも、図５の鎖線で示すように袋ナット２が貫通孔２２付近を中心として傾動することで、袋ナット２の軸線ｋ１を足場用壁つなぎ６の軸線ｋ２と一致するように修正して無理なく容易に接続させることができる。   Even when the axis of the scaffolding wall tether 6 is misaligned with the axis of the drill screw 1 when the male threaded part 61 of the scaffolding wall tether 6 is screwed to the female threaded portion 21 of the cap nut 2, FIG. As indicated by the chain line, the cap nut 2 tilts around the vicinity of the through hole 22 so that the axis k1 of the cap nut 2 is corrected so as to coincide with the axis k2 of the scaffolding wall tether 6 and can be easily and easily connected. be able to.

以上説明してきたように、この実施例の足場用壁つなぎ取付ボルトでは、弾性セットリング３と弾性クッション４により、袋ナット２とドリルビス１が、袋ナット２の雌ねじ部２１側からドリルビス１の丸さら頭部１２が見える状態に予め組み付けられた状態になっているため、プラスドライバー５でドリルビス１を回転させる際に、丸さら頭部１２の係合部１１に対しプラスドライバー５を容易に係合させることができると共に、プラスドライバー５の軸線をドリルビス１の軸線に合わせた状態で回転駆動させることができるようになる。   As described above, in the anchoring wall connecting bolt of this embodiment, the cap nut 2 and the drill screw 1 are moved from the female screw portion 21 side of the cap nut 2 by the elastic set ring 3 and the elastic cushion 4. When the drill screw 1 is rotated with the Phillips screwdriver 5, the Phillips screwdriver 5 can be easily engaged with the engaging portion 11 of the round flat head 12 because the flat head 12 is assembled in advance. In addition, it can be rotated and driven with the axis of the Phillips screwdriver 5 aligned with the axis of the drill screw 1.

また、丸さら頭部１２の最大外形部が袋ナット２における雌ねじ部２１の開口端部より外部に突出しない範囲で袋ナット２の雌ねじ部１２側から丸さら頭部１２が見える位置より奧に移動しないようにドリルビス１が仮止め規制されることにより、ドリルビス１に対する袋ナット２の傾動が規制された状態になっているため、丸さら頭部１２の係合部１１に対するプラスドライバー５の係合操作やドリルビス１の回転操作の際に、足場用壁つなぎ取付ボルトを安定した状態に保持させることができるようになる。   Further, in the range where the maximum outer shape of the round head 12 does not protrude outward from the open end of the female screw 21 in the cap nut 2, the position of the round head 12 can be seen from the position where the female screw 12 of the cap nut 2 can be seen. By restricting the drill screw 1 so as not to move, the tilting of the cap nut 2 with respect to the drill screw 1 is restricted, so that the screwdriver 5 is engaged with the engaging portion 11 of the round head 12. During the joint operation or the rotation operation of the drill screw 1, the scaffolding wall connecting attachment bolt can be held in a stable state.

従って、作業性を高めることができるようになるという効果が得られる。   Therefore, an effect that workability can be improved is obtained.

また、袋ナット２とドリルビス１は互いに分離可能であるため、使用によりドリルビス１の先端ドリル１３が摩耗したり刃こぼれした場合には、袋ナット２の再利用が可能で、コストの低減化が図れるようになる。   Further, since the cap nut 2 and the drill screw 1 are separable from each other, if the tip drill 13 of the drill screw 1 is worn or spills due to use, the cap nut 2 can be reused, and the cost can be reduced. It will be able to plan.

また、ドリルビス１の頭部が丸さら頭部１２で構成されることにより、ドリルビス１の丸さら頭部１２に対する袋ナット２の揺動がスムーズに行えるようになる。   Further, since the head of the drill screw 1 is constituted by the round head 12, the cap nut 2 can be smoothly swung with respect to the round head 12 of the drill screw 1.

また、丸さら頭部１２はプラスドライバー５の係合部１１を深く形成することができるため、丸さら頭部１２に対するプラスドライバー５の係合強度を高めることができるようになる。   Further, since the round head 12 can form the engaging portion 11 of the plus driver 5 deeply, the strength of the plus driver 5 engaging with the round head 12 can be increased.

以上本実施例を説明してきたが、本発明は上述の実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等があっても、本発明に含まれる。   Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention.

例えば、実施例では、ドリルビス１の頭部として回転工具としてプラスドライバー５を用いる場合のプラス状係合部１１を備えた丸さら頭部１２を例示したが、頭部や係合部の形状は任意である。   For example, in the embodiment, the round head 12 having the plus engagement portion 11 in the case where the plus screwdriver 5 is used as the rotary tool as the head of the drill screw 1 is illustrated, but the shape of the head and the engagement portion is as follows. Is optional.
