Embodiments of the present invention will be described in detail below with reference to the drawings as appropriate.
<<Embodiment 1>>
First, the procedure for using the decorative cap member for the scaffold connecting anchor will be explained, and then each structure will be explained.
As shown in FIG. 2, when constructing the outer wall K of a building, scaffolding is erected on the outer wall K.
When assembling the scaffold, a plurality of anchor holes k1 are provided in the outer wall K. Then, a scaffold connecting anchor 100 having a female thread 100n formed in a central hole 100a shown in FIG. 3(a) is driven into the anchor hole k1 (arrow α11 in FIG. 1).

なお、足場つなぎアンカー100は、円筒形状を有している。足場つなぎアンカー100の奥側には、アンカー用の穴k1からの抜け防止材101が嵌合されている。 Note that the scaffold tethering anchor 100 has a cylindrical shape. A material 101 for preventing the anchor from coming off from the anchor hole k1 is fitted on the back side of the scaffold connecting anchor 100.

そして、足場つなぎアンカー100に足場用のアンカーボルトがボルト締めされ、足場が組まれる。
工事が終了後、アンカー用の穴k1を見えなくする作業(化粧作業)が行われる。
Scaffold anchor bolts are then bolted to the scaffold connecting anchors 100, and the scaffold is erected.
After the construction is completed, work (cosmetic work) is performed to make the anchor hole k1 invisible.

アンカー用の穴k1に設けられた足場つなぎアンカー100の雌ねじ100nに、実施形態1の止水ボルト2を含む足場つなぎアンカー用化粧キャップ部材1が打ち込まれる。
キャップ部3aが外壁Kに設けられるので一連の作業が終了する。
The decorative cap member 1 for a scaffold tethering anchor including the water stop bolt 2 of the first embodiment is driven into the female thread 100n of the scaffold tethering anchor 100 provided in the anchor hole k1.
Since the cap portion 3a is provided on the outer wall K, the series of operations is completed.

足場つなぎアンカー用化粧キャップ部材1は、止水ボルト2と化粧キャップ3とゴムパッキン4とを備えている。以下構成について説明する。 A decorative cap member 1 for a scaffold connecting anchor includes a water stop bolt 2, a decorative cap 3, and a rubber packing 4. The configuration will be explained below.

<止水ボルト2>
止水ボルト2は、樹脂成形される。止水ボルト2は、雄ねじ2mをもつねじ軸2aとねじ頭2bとを有している。
止水ボルト2は、使い捨てである。止水ボルト2は、足場つなぎアンカー100を再利用するために用いられるものであり、化粧キャップ3等とともに一式で使用されるものである。
この際、足場つなぎアンカー100の雌ねじ100nと止水ボルト2の雄ねじ2mが合うことでソケットレンチでスムーズに外せる。
下記の止水ボルト2の第1雄ねじ2m1と第2雄ねじ2m2は、足場つなぎアンカー100の雌ねじ100nと同じねじなので、一番スムーズに外せる。
止水ボルト2のねじ頭2bには、化粧キャップ3のキャップ軸3dが嵌入されるキャップ穴2b1が形成されている。ねじ頭2bは、六角形に形成されている。また、根元2a1とねじ頭2bとの間にねじ頭2bよりも大径となるフランジが形成されている。
<Water stop bolt 2>
The water stop bolt 2 is resin molded. The water stop bolt 2 has a screw shaft 2a with a male thread 2m and a screw head 2b.
The water stop bolt 2 is disposable. The water stop bolt 2 is used to reuse the scaffolding anchor 100, and is used as a set together with the decorative cap 3 and the like.
At this time, by matching the female thread 100n of the scaffold connecting anchor 100 with the male thread 2m of the water stop bolt 2, it can be removed smoothly with a socket wrench.
The first male thread 2m1 and second male thread 2m2 of the water stop bolt 2 shown below are the same as the female thread 100n of the scaffolding anchor 100, so they can be removed most smoothly.
The screw head 2b of the water stop bolt 2 is formed with a cap hole 2b1 into which the cap shaft 3d of the decorative cap 3 is inserted. The screw head 2b is formed in a hexagonal shape. Further, a flange having a larger diameter than the screw head 2b is formed between the root two a1 and the screw head 2b.

ねじ軸2aには、雄ねじ2mが形成されている。
止水ボルト2の雄ねじ2mは、足場つなぎアンカー100の雌ねじ100nと同じピッチの2つの雄ねじ(第1雄ねじ2m1と第2雄ねじ2m2)が、π位相をずらして形成されている。すなわち、ねじ軸2aの雄ねじ2mは、足場つなぎアンカー100の雌ねじ100nのピッチp1と同じピッチp1の第1雄ねじ2m1と第2雄ねじ2m2とがそれぞれ雌ねじ100nのねじ山間に形成されている。
図5に示すように、第1雄ねじ2m1は雌ねじ100nのねじ山100n1に接触し、第2雄ねじ2m2は雌ねじ100nのねじ山100n2に接触する。
A male thread 2m is formed on the screw shaft 2a.
The male thread 2m of the water stop bolt 2 is formed by two male threads (a first male thread 2m1 and a second male thread 2m2) having the same pitch as the female thread 100n of the scaffold connecting anchor 100 and shifted in phase by π. That is, in the male thread 2m of the screw shaft 2a, a first male thread 2m1 and a second male thread 2m2 having the same pitch p1 as the female thread 100n of the scaffolding anchor 100 are formed between the threads of the female thread 100n.
As shown in FIG. 5, the first male thread 2m1 contacts the thread 100n1 of the female thread 100n, and the second male thread 2m2 contacts the thread 100n2 of the female thread 100n.

そのため、雄ねじ2mのピッチp2(第1雄ねじ2m1と第2雄ねじ2m2間の距離)は、足場つなぎアンカー100の雌ねじ100n(図2参照)のピッチp1より小さいピッチで形成されている。
また、止水ボルト2の雄ねじ2mのねじ山の高さh2は、足場つなぎアンカー100の雌ねじ100nのねじ山の高さh1より小さく形成されている。
Therefore, the pitch p2 of the male thread 2m (distance between the first male thread 2m1 and the second male thread 2m2) is smaller than the pitch p1 of the female thread 100n (see FIG. 2) of the scaffold connecting anchor 100.
Further, the height h2 of the thread of the male thread 2m of the water stop bolt 2 is smaller than the height h1 of the thread of the female thread 100n of the scaffold connecting anchor 100.

例えば、本実施形態では、止水ボルト2の雄ねじ2mのピッチp2を、足場つなぎアンカー100の雌ねじ100nのピッチp1の1/2とした場合を示している。また、止水ボルト2における雄ねじ2mのねじ山の高さh2を、足場つなぎアンカー100の雌ねじ100nのねじ山の高さh1の1/2の高さとした場合を示している。 For example, in this embodiment, the pitch p2 of the male thread 2m of the water stop bolt 2 is set to 1/2 of the pitch p1 of the female thread 100n of the scaffolding anchor 100. Further, a case is shown in which the height h2 of the thread of the male thread 2m in the water stop bolt 2 is set to 1/2 of the height h1 of the thread of the female thread 100n of the scaffold connecting anchor 100.

そして、実施形態1では、足場つなぎアンカー100の雌ねじ100n(図6(a)、(b))と止水ボルト2の雄ねじ2m(図7(a)、(b))の位相を異ならせて構成しいる。
図6(b)に示すように、足場つなぎアンカー100は、雌ねじ100nの切り始めが始点100n0である。
図7(b)に示すように、止水ボルト2は、雄ねじ2mの切り始めが始点2m0である。
In Embodiment 1, the phases of the female thread 100n (FIGS. 6(a) and (b)) of the scaffold connecting anchor 100 and the male thread 2m (FIGS. 7(a) and (b)) of the water stop bolt 2 are made different. Composition book.
As shown in FIG. 6(b), in the scaffold connecting anchor 100, the starting point 100n0 is the beginning of cutting the female thread 100n.
As shown in FIG. 7(b), the water stop bolt 2 has a starting point 2m0 at which the male thread 2m starts cutting.

止水ボルト2の雄ねじ2mの切り始め(始点m0)は、足場つなぎアンカー100の雌ねじ100nの始点100n0に対して位相θがπ(180度)遅れている。すなわち、止水ボルト2の雄ねじ2mは、足場つなぎアンカー100の雌ねじ100nに対して位相がπ(180度)遅れて形成されている。 The cutting start (starting point m0) of the male thread 2m of the water stop bolt 2 is delayed in phase θ by π (180 degrees) with respect to the starting point 100n0 of the female thread 100n of the scaffolding anchor 100. That is, the male thread 2m of the water stop bolt 2 is formed to be delayed in phase by π (180 degrees) with respect to the female thread 100n of the scaffolding anchor 100.

足場つなぎアンカー100の雌ねじ100nと止水ボルト2の雄ねじ2mの位相とが異なることで、止水ボルト2は足場つなぎアンカー100の雌ねじ100nの内部に止水ボルト2の2つの雄ねじ2mを配置でき、円滑に打ち込む(嵌合する)ことができる。 Because the phases of the female thread 100n of the scaffolding anchor 100 and the male thread 2m of the water stop bolt 2 are different, the two male threads 2m of the water stop bolt 2 can be placed inside the female thread 100n of the scaffolding anchor 100. , it can be driven in (fitted) smoothly.

足場つなぎアンカー用化粧キャップ部材1の外部空間側には化粧キャップ3が嵌合されている。化粧キャップ3のキャップ部3aは、外壁Kの外面仕上げKg(図2参照)と同じ模様とされている。例えば、外壁Kの外面仕上げKgがタイル仕上げの場合には、キャップ部3aはタイル仕上げ模様とされる。 A decorative cap 3 is fitted on the external space side of the decorative cap member 1 for the scaffold connecting anchor. The cap portion 3a of the decorative cap 3 has the same pattern as the outer surface finish Kg of the outer wall K (see FIG. 2). For example, when the outer surface finish Kg of the outer wall K is a tile finish, the cap portion 3a has a tile finish pattern.

化粧キャップ3は、キャップ部3aと球体3c(図11参照)を有する支持軸部3bとが形成されている。化粧キャップ3は、支持軸部3bの球体3cにキャップ軸3dが嵌合され構成されている。化粧キャップ3は、球体3cがあることでキャップ部3aがキャップ軸3dに対して、直交する位置関係から所定角度傾斜することができるようになっている。 The decorative cap 3 includes a cap portion 3a and a support shaft portion 3b having a sphere 3c (see FIG. 11). The decorative cap 3 is constructed by fitting a cap shaft 3d into a spherical body 3c of a support shaft portion 3b. In the cosmetic cap 3, the presence of the sphere 3c allows the cap portion 3a to be tilted at a predetermined angle from a positional relationship perpendicular to the cap axis 3d.

なお、止水ボルト2のねじ軸2aの根元2a1には、一例としてここでは、ゴムパッキン4が予め嵌められている。図3(a)、図3(b)に示すように、ゴムパッキン4は中央に孔4aが形成された環形状に形成されている。 As an example, here, a rubber packing 4 is fitted in advance to the base two a1 of the threaded shaft 2a of the water stop bolt 2. As shown in FIGS. 3(a) and 3(b), the rubber packing 4 is formed in an annular shape with a hole 4a formed in the center.

ゴムパッキン4は、胴部4aと鍔部4bとを有している。鍔部4bには、胴部4aから次第に径が太くなる円錐状部4b1を有している。円錐状部4b1は足場つなぎアンカー用化粧キャップ部材1が打ち込まれる際にゴムパッキン4が滑らかにアンカー用の穴k1に摺動してシールすることができる大きさに形成されている。 The rubber packing 4 has a body portion 4a and a collar portion 4b. The collar portion 4b has a conical portion 4b1 whose diameter gradually increases from the body portion 4a. The conical portion 4b1 is formed in a size that allows the rubber packing 4 to smoothly slide into and seal the anchor hole k1 when the decorative cap member 1 for the scaffold connecting anchor is driven in.

足場つなぎアンカー用化粧キャップ部材1を使用する場合は、止水ボルト2の外部空間側からねじ頭2bのキャップ穴2b1に化粧キャップ3のキャップ軸3dが嵌められ、止水ボルト2のねじ軸2aの根元2a1には、環状のゴムパッキン4(図3(b)参照)が弾性変形させて嵌められる。 When using the decorative cap member 1 for scaffold connecting anchor, the cap shaft 3d of the decorative cap 3 is fitted into the cap hole 2b1 of the screw head 2b from the external space side of the water stop bolt 2, and the screw shaft 2a of the water stop bolt 2 is inserted into the cap hole 2b1 of the screw head 2b. An annular rubber packing 4 (see FIG. 3(b)) is elastically deformed and fitted into the root two a1.

<足場つなぎアンカー用化粧キャップ部材1の足場つなぎアンカー100への組み付け>
次に、足場つなぎアンカー用化粧キャップ部材1の足場つなぎアンカー100への組み付け方法について説明する。
<Assembling the decorative cap member 1 for the scaffold connecting anchor to the scaffold connecting anchor 100>
Next, a method for assembling the decorative cap member 1 for a scaffold connecting anchor to the scaffold connecting anchor 100 will be explained.

図3(a)に示すように、止水ボルト2の根元2a1に、孔4aを嵌入してゴムパッキン4を嵌める(図2参照)。
続いて、ゴムパッキン4を嵌めた止水ボルト2のねじ頭2bのキャップ穴2b1に、化粧キャップ3のキャップ軸3dを嵌入して、化粧キャップ3を止水ボルト2のねじ頭2bに取り付ける。
続いて、図1に示すように、外壁Kにアンカー用の穴k1内の足場つなぎアンカー100の雌ねじ100nの内部に、足場つなぎアンカー用化粧キャップ部材1における止水ボルト2の雄ねじ2mを合わせて、足場つなぎアンカー100の雌ねじ100nの内部に足場つなぎアンカー用化粧キャップ部材1を打ち入れる。そして、足場つなぎアンカー用化
粧キャップ部材1の化粧キャップ3が外壁Kと面一になるようにする。
ハンマーは、金属よりもプラスチック製であることが好ましく、ハンマーの直径が化粧キャップ3の直径よりも大きいことで、ハンマーが外壁Kまで化粧キャップ3を殴打すると外壁Kと同じ面上にすることができる。または、当て板を当てて金属ハンマーで殴打しても良い。
例えば、図25、図26に示す従来の足場つなぎアンカー100の雌ねじ100nと同じピッチの止水ボルト101では、化粧キャップ103が外壁Kとの間に最大で足場つなぎアンカー100の雌ねじ100nのピッチの高低差が発生する。
これに対して、本実施形態では、止水ボルト2の雄ねじ2mのピッチp2の高低差しか生じない。
As shown in FIG. 3(a), the hole 4a is inserted into the base 2a1 of the water stop bolt 2, and the rubber packing 4 is fitted therein (see FIG. 2).
Subsequently, the cap shaft 3d of the decorative cap 3 is fitted into the cap hole 2b1 of the screw head 2b of the water stop bolt 2 into which the rubber packing 4 is fitted, and the decorative cap 3 is attached to the screw head 2b of the water stop bolt 2.
Next, as shown in FIG. 1, align the external thread 2m of the water stop bolt 2 of the decorative cap member 1 for the scaffolding anchor 1 with the internal thread 100n of the scaffolding anchor 100 in the hole k1 for the anchor in the outer wall K. , the decorative cap member 1 for the scaffold connecting anchor is driven into the internal thread 100n of the scaffold connecting anchor 100. Then, it was used as a scaffolding anchor.
The decorative cap 3 of the decorative cap member 1 is made flush with the outer wall K.
The hammer is preferably made of plastic rather than metal, and the diameter of the hammer is larger than the diameter of the decorative cap 3, so that when the hammer hits the decorative cap 3 up to the outer wall K, it can be on the same plane as the outer wall K. can. Alternatively, you can apply a patch and hit with a metal hammer.
For example, in a water stop bolt 101 having the same pitch as the female thread 100n of the conventional scaffolding anchor 100 shown in FIG. 25 and FIG. Differences in elevation occur.
On the other hand, in this embodiment, only the height difference occurs in the pitch p2 of the male thread 2m of the water stop bolt 2.

止水ボルト2は樹脂で成形されている。そして、止水ボルト2は、雄ねじ2mのピッチp2を足場つなぎアンカー100の雌ねじ100n(図5参照)のピッチp1より小さくするとともに、止水ボルト2の雄ねじ2mのねじ山の高さh2を、足場つなぎアンカー100の雌ねじ100nのねじ山の高さh1より小さく形成している。
足場つなぎアンカー用化粧キャップ部材1は、足場つなぎアンカー100の内部に打ち込まれると、止水ボルト2の雄ねじ2mが弾性変形して、止水ボルト2を足場つなぎアンカー100の内部に打ち入れることができる。
The water stop bolt 2 is molded from resin. The water stop bolt 2 has a pitch p2 of the male thread 2m smaller than a pitch p1 of the female thread 100n (see FIG. 5) of the scaffold connecting anchor 100, and a thread height h2 of the male thread 2m of the water stop bolt 2. The height h1 of the thread of the female thread 100n of the scaffold connecting anchor 100 is smaller than the height h1.
When the decorative cap member 1 for a scaffold connecting anchor is driven into the inside of the scaffold connecting anchor 100, the male thread 2m of the water stop bolt 2 is elastically deformed, and the water stop bolt 2 can be driven into the inside of the scaffold connecting anchor 100. can.

したがって、外壁Kのアンカー用の穴k1を見えなくする作業が容易である。また、足場つなぎアンカー用化粧キャップ部材1を打ち込むので、足場つなぎアンカー用化粧キャップ部材1の化粧キャップ3を外壁Kと面一にし易い。
さらに、足場つなぎアンカー用化粧キャップ部材1を打ち込んで調整できる構成であるので、足場つなぎアンカー100に打ち込まれる長さにより、外壁Kから化粧キャップ3が突出したり、凹んだりする事象を減少できる。
こうして、外壁Kのアンカー用のすべての穴k1に足場つなぎアンカー用化粧キャップ部材1を打ち込むことで穴k1を見えなくする作業(化粧作業)が終了する。
足場つなぎアンカー用化粧キャップ部材1は、前記したように、次回工事に再利用することが可能となる。つまり、止水ボルト2から化粧キャップ3を取り外し、ねじ頭2bをソケットレンチに係合して回すことで取り外すことができる。
なお、止水ボルト2の雄ねじ2mは、足場つなぎアンカー100の雌ねじ100nの1/2ピッチのピッチp2の雄ねじ2m3で構成してもよい。
Therefore, it is easy to make the anchor hole k1 in the outer wall K invisible. Moreover, since the decorative cap member 1 for the scaffold connecting anchor is driven in, the decorative cap 3 of the decorative cap member 1 for the scaffold connecting anchor can be easily made flush with the outer wall K.
Furthermore, since the structure is such that the decorative cap member 1 for the scaffold connecting anchor can be driven in and adjusted, it is possible to reduce the phenomenon in which the decorative cap 3 protrudes from the outer wall K or is recessed depending on the length driven into the scaffold connecting anchor 100.
In this way, the work (decoration work) of making the holes k1 invisible is completed by driving the decorative cap members 1 for scaffold connecting anchors into all the holes k1 for anchors in the outer wall K.
As described above, the decorative cap member 1 for the scaffold connecting anchor can be reused for the next construction work. That is, it can be removed by removing the decorative cap 3 from the water stop bolt 2, engaging the screw head 2b with a socket wrench, and turning it.
The male screw 2m of the water stop bolt 2 may be configured with a male screw 2m3 having a pitch p2 that is 1/2 the pitch of the female screw 100n of the scaffolding anchor 100.

<変形例1>
変形例1は、図9に示すように、止水ボルト22の雄ねじ22mの外周部がねじ頭部22bの側から雄ねじ22mの先端22a1の側まで軸方向に沿って除去された面取り箇所22m1が1箇所以上ある構成としたものである。その他の構成は、雄ねじ22mのピッチが足場つなぎアンカー100の雌ねじ100nのピッチp1の1/2であること以外、実施形態1と同様であるから、実施形態1と同一の構成要素には20番台の符号を付して示し、詳細な説明は省略する。
<Modification 1>
In modification example 1, as shown in FIG. 9, a chamfered portion 22m1 is removed along the axial direction from the screw head 22b side to the tip 22a1 side of the male screw 22m on the outer circumference of the male thread 22m of the water stop bolt 22. This configuration has one or more locations. The other configuration is the same as that of Embodiment 1 except that the pitch of the male thread 22m is 1/2 of the pitch p1 of the female thread 100n of the scaffold connecting anchor 100. The detailed explanation will be omitted.

変形例1の止水ボルト22のねじ軸22aには、雄ねじ22mが形成されている。そして、雄ねじ22mの外周部がねじ頭部22bの側から雄ねじ22mの先端22a1の側まで軸方向に沿って除去された面取り箇所22m1が1例として4箇所形成されている。
変形例1によれば、止水ボルト22のねじ軸22aに、雄ねじ22mの半径r1より小さい半径r2をもつ平面の面取り箇所22m1が形成されるので、足場つなぎアンカー用化粧キャップ部材1を足場つなぎアンカー100の内部に打ち込むに際して、足場つなぎアンカー100の雌ねじ100aと止水ボルト22の雄ねじ22mとが干渉するエリアが少なくなる。そのため、止水ボルト22をもつ足場つなぎアンカー用化粧キャップ部材1の足場つなぎアンカー100の内部への打ち込み作業が容易になる。
また、止水ボルト22の雄ねじ22mのピッチが足場つなぎアンカー100の雌ねじ100nのピッチp1の1/2ピッチとし、面取り箇所22m1を形成することで、止水ボルト22を次回工事の時に再利用する場合、足場つなぎアンカー100の雌ねじ100nのねじ山に倣ってソケットレンチで外すことができる。
A male thread 22m is formed on the threaded shaft 22a of the water stop bolt 22 of Modification 1. As an example, four chamfered portions 22m1 are formed by removing the outer peripheral portion of the male screw 22m along the axial direction from the screw head 22b side to the tip 22a1 side of the male screw 22m.
According to the first modification, a flat chamfered portion 22m1 having a radius r2 smaller than the radius r1 of the male screw 22m is formed on the threaded shaft 22a of the water stop bolt 22, so that the decorative cap member 1 for the scaffold connecting anchor is connected to the scaffold. When driving into the interior of the anchor 100, the area where the female thread 100a of the scaffold connecting anchor 100 and the male thread 22m of the water stop bolt 22 interfere is reduced. Therefore, it becomes easy to drive the decorative cap member 1 for scaffolding anchor 1 having the water stop bolt 22 into the inside of the scaffolding anchor 100.
In addition, the pitch of the male thread 22m of the water stop bolt 22 is set to 1/2 the pitch p1 of the female thread 100n of the scaffold connecting anchor 100, and by forming the chamfered portion 22m1, the water stop bolt 22 can be reused for the next construction. In this case, it can be removed using a socket wrench following the threads of the female screw 100n of the scaffolding anchor 100.

なお、変形例1では面取り箇所22m1が4箇所形成された場合を例に挙げて説明したが、1箇所以上あればよく、変形例1の上記効果を奏する。 In addition, although the case where the chamfered portions 22m1 are formed at four locations has been described as an example in the first modified example, it is sufficient that there are one or more chamfered portions, and the above effects of the first modified example are achieved.

<変形例2>
変形例2の足場つなぎアンカー用化粧キャップ部材31(図11参照)における止水ボルト32は、図12(a)、(b)に示すように、ねじ頭部32bに化粧キャップ3の支持軸部3bを嵌合するキャップ穴32b1を有している。そして、キャップ穴32b1の周辺部に化粧キャップ3の支持軸部3bが嵌入された際に変形代となる凹形状の逃げ部32b2が形成されている。
<Modification 2>
As shown in FIGS. 12(a) and 12(b), the water stop bolt 32 in the decorative cap member 31 for a scaffold connecting anchor (see FIG. 11) of Modification 2 has a support shaft portion of the decorative cap 3 attached to the screw head 32b. It has a cap hole 32b1 into which the cap hole 32b is fitted. A concave relief portion 32b2 is formed around the cap hole 32b1 to allow for deformation when the support shaft portion 3b of the decorative cap 3 is fitted.

また、止水ボルト32は、ねじ頭部32bとねじ軸32aとの間に防水用のツバ部32cが一体に形成されている。
図12(a)、(b)に示すように、ツバ部32cは、所定の厚みで外周部32c1をもつ円板状に形成されている。ツバ部32cの外径d2(図12(a)、(b))は、アンカー用の穴k1の径d1(図11参照)より大きな径を有している。なお、外周部32c1の厚みは、例えば、0.4~0.8mmの範囲であるとスムーズに打ち込むことができる。
これにより、図11に示すように、ツバ部32cの外周部32c1は、足場つなぎアンカー用の穴k1を覆い、外壁Kのアンカー用の穴k1と外部空間とをシールすることができる。
Further, the water stop bolt 32 has a waterproof collar 32c integrally formed between the screw head 32b and the screw shaft 32a.
As shown in FIGS. 12(a) and 12(b), the collar portion 32c is formed into a disk shape with a predetermined thickness and an outer peripheral portion 32c1. The outer diameter d2 of the collar portion 32c (FIGS. 12(a) and 12(b)) is larger than the diameter d1 of the anchor hole k1 (see FIG. 11). Note that if the thickness of the outer peripheral portion 32c1 is in the range of, for example, 0.4 to 0.8 mm, it can be driven smoothly.
Thereby, as shown in FIG. 11, the outer peripheral part 32c1 of the collar part 32c can cover the hole k1 for the scaffold connecting anchor and seal the hole k1 for the anchor in the outer wall K and the external space.

ねじ頭32bにおける逃げ部32b2は、ねじ頭部32bに環状の凹形状をもつ凹部として形成されている。
キャップ穴32b1と逃げ部32b2との間には、環形状の変形肉32b3が形成されている。
キャップ穴32b1の周辺部に凹形状の逃げ部32b2が形成されることで、図11に示すように、化粧キャップ3の球体3cを有する支持軸部3bがキャップ穴32b1に嵌入された際、環形状の変形肉32b3が弾性変形して逃げ部32b2に入り込む。そのため、化粧キャップ3の球体3cを有する支持軸部3bを円滑にキャップ穴32b1に嵌入できる。
The relief portion 32b2 in the screw head 32b is formed as a concave portion having an annular concave shape in the screw head 32b.
An annular deformed portion 32b3 is formed between the cap hole 32b1 and the relief portion 32b2.
By forming the concave relief part 32b2 around the cap hole 32b1, as shown in FIG. The deformed meat 32b3 is elastically deformed and enters the relief portion 32b2. Therefore, the support shaft portion 3b having the spherical body 3c of the decorative cap 3 can be smoothly fitted into the cap hole 32b1.

また、図11に示すように、化粧キャップ3に別部品のキャップ軸3d(図3(a)参照)を用いることなく、化粧キャップ3を直接ねじ頭32bに嵌めることができる。
したがって、化粧キャップ3の止水ボルト32への取り付けが容易である。
また、足場つなぎアンカー用化粧キャップ部材31がアンカー用の穴k1に嵌入された際、止水ボルト32のツバ部32cがアンカー用の穴k1の径d1(図11参照)より大きな外径d2(図12(a)参照)をもつので、ツバ部32cによって、アンカー用の穴k1(図11参照)を塞ぎ、シールすることができる。
Further, as shown in FIG. 11, the cosmetic cap 3 can be directly fitted onto the screw head 32b without using a separate cap shaft 3d (see FIG. 3(a)).
Therefore, attachment of the decorative cap 3 to the water stop bolt 32 is easy.
Furthermore, when the decorative cap member 31 for the scaffold connecting anchor is inserted into the anchor hole k1, the collar portion 32c of the water stop bolt 32 has an outer diameter d2 (larger than the diameter d1 (see FIG. 11) of the anchor hole k1). 12(a)), the anchor hole k1 (see FIG. 11) can be closed and sealed by the collar portion 32c.

また、シール機能をもつツバ部32cが止水ボルト32と一体成形されるので、防水ゴム102p(図25、図26参照)が不要になる。そのため、部品点数を削減できる。また、防水ゴム102pを止水ボルト102(図25参照)に嵌める組立て作業が解消し、組立て性が向上する。 Further, since the collar portion 32c having a sealing function is integrally molded with the water stop bolt 32, the waterproof rubber 102p (see FIGS. 25 and 26) becomes unnecessary. Therefore, the number of parts can be reduced. Further, the assembly work of fitting the waterproof rubber 102p into the water stop bolt 102 (see FIG. 25) is eliminated, and the ease of assembly is improved.

<変形例3>
変形例3の止水ボルト42(図13(a)参照)は、ねじ軸42aの先端部42a1から突出した案内突出片42tを形成してもよい。
図13(a)、(b)に示すように、案内突出片42tは、ねじ軸42aの先端部42a1から突出して一対形成されている。案内突出片42tは、足場つなぎアンカー100の筒内に足場つなぎアンカー用化粧キャップ部材41を打ち込む際に円滑に入るように、ねじ軸42aを足場つなぎアンカー100の内部に案内する。
<Modification 3>
The water stop bolt 42 of Modification 3 (see FIG. 13(a)) may have a guide protrusion 42t protruding from the tip 42a1 of the screw shaft 42a.
As shown in FIGS. 13(a) and 13(b), a pair of guide protruding pieces 42t are formed to protrude from the tip end 42a1 of the screw shaft 42a. The guide projection piece 42t guides the screw shaft 42a into the inside of the scaffolding anchor 100 so that it can smoothly enter the decorative cap member 41 for the scaffolding anchor 100 when it is driven into the cylinder of the scaffolding anchor 100.

図13(a)に示すように、一対の案内突出片42tは、それぞれ雄ねじ42mの外径d3より小さい外径d4(図14参照)を有している。換言すれば、案内突出片42tの半径r1はそれぞれ雄ねじ42mの外形の半径r2より小さい。
案内突出片42tは、長い本体部42t1とテーパ部42t2とを有している。
テーパ部42t2は、案内突出片42tの先端部に形成されている。テーパ部42t2は、先端側にいくほど内側に位置する傾斜を有している。また、案内突出片42tの根元内側には、凹形状の切り込み42t3が形成されている。
As shown in FIG. 13(a), the pair of guide projection pieces 42t each have an outer diameter d4 (see FIG. 14) smaller than the outer diameter d3 of the male thread 42m. In other words, the radius r1 of each of the guide protruding pieces 42t is smaller than the radius r2 of the outer shape of the male screw 42m.
The guide projection piece 42t has a long main body portion 42t1 and a tapered portion 42t2.
The tapered portion 42t2 is formed at the tip of the guide projection piece 42t. The tapered portion 42t2 has an inclination that is located inward toward the distal end side. Furthermore, a concave notch 42t3 is formed inside the base of the guide projection piece 42t.

変形例3によれば、止水ボルト42のねじ軸42aの先端部42a1に足場つなぎアンカー100の雌ねじ100nの内径d3の内側に位置する外径d4をもつ案内突出片42tを有する。そのため、足場つなぎアンカー用化粧キャップ部材41を足場つなぎアンカー100の筒内に嵌入する(図14の矢印α12)際、足場つなぎアンカー用化粧キャップ部材41を足場つなぎアンカー100の内部に、案内突出片42tが案内することで円滑に打ち込むことができる(嵌入できる)。
また、案内突出片42tの先端部にテーパ部42t2を有するとともに案内突出片42tの根元内側に凹形状の切り込み42t3が形成されるので、外壁Kにおけるアンカー用の穴k1の足場つなぎアンカー100が浅く、案内突出片42tが抜け防止材101(図3(a)参照)に当たっても、案内突出片42tが柔軟に内側に曲がることができる。
According to the third modification, the tip 42a1 of the threaded shaft 42a of the water stop bolt 42 has a guide protrusion 42t having an outer diameter d4 located inside the inner diameter d3 of the female thread 100n of the scaffolding anchor 100. Therefore, when fitting the decorative cap member 41 for the scaffold connecting anchor into the cylinder of the scaffold connecting anchor 100 (arrow α12 in FIG. 14), the decorative cap member 41 for the scaffold connecting anchor is inserted into the inside of the scaffold connecting anchor 100, and the guiding protrusion The 42t guides it so that it can be driven in smoothly (it can be inserted).
Further, since the guide projection piece 42t has a tapered portion 42t2 at the tip and a concave cut 42t3 is formed inside the base of the guide projection piece 42t, the scaffold connecting anchor 100 in the anchor hole k1 in the outer wall K is shallow. Even if the guiding protruding piece 42t hits the slip-off prevention member 101 (see FIG. 3(a)), the guiding protruding piece 42t can flexibly bend inward.

なお、変形例3では、案内突出片42tを雄ねじ軸42aの先端部42a1に一対(2つ)形成する場合を説明したが、案内突出片42tを3つ以上形成してもよい。なお、案内突出片42tを約180度間隔で3つ形成すれば、2次元平面での案内が行い易い。 In the third modification, a case has been described in which a pair (two) of the guide protrusions 42t are formed on the tip end portion 42a1 of the male threaded shaft 42a, but three or more guide protrusions 42t may be formed. Note that if three guiding protruding pieces 42t are formed at intervals of about 180 degrees, guiding on a two-dimensional plane can be easily performed.

<変形例4>
足場つなぎアンカー100の打ち込みで浅いものと深いものがある。
深さに対応するには、足場つなぎアンカー用化粧キャップ部材1(図1参照)の違う長さのものを準備しなければならない。そこで、止水ボルト102を準備して現場で雄ねじ102m(図25参照)を切断すると切断部分にバリや返りが出てねじがスムーズに入らない場合がある。
<Modification 4>
There are two types of driving of the scaffold connecting anchor 100: shallow and deep.
To accommodate different depths, different lengths of the decorative cap member 1 (see FIG. 1) for the scaffold tether anchor must be prepared. Therefore, if the water stop bolt 102 is prepared and the male thread 102m (see FIG. 25) is cut on site, burrs or burrs may appear on the cut portion, and the screw may not be inserted smoothly.

この問題に対応する構成が下記の変形例4である。
変形例4の足場つなぎアンカー用化粧キャップ部材51(図15参照)は止水ボルト52を有している。止水ボルト52は、ねじ軸52aとねじ頭部52bとを有している。
そして、止水ボルト52のねじ軸52aは、軸方向において雄ねじ52mのねじ谷52m0の径d5よりも小さな径d6をもつねじ山が形成されていない円柱状の非ねじ軸52hが設けられている。
A configuration that addresses this problem is Modified Example 4 below.
A decorative cap member 51 for a scaffold connecting anchor (see FIG. 15) of Modification 4 has a water stop bolt 52. The water stop bolt 52 has a screw shaft 52a and a screw head 52b.
The threaded shaft 52a of the water stop bolt 52 is provided with a cylindrical non-threaded shaft 52h in which no thread is formed and has a diameter d6 smaller than the diameter d5 of the thread valley 52m0 of the male thread 52m in the axial direction. .

つまり、ねじ軸52aには、非ねじ軸52hを挟んで、2箇所に雄ねじ52mが形成されている。
足場つなぎアンカー用化粧キャップ部材51の使用に際して、足場つなぎアンカー100の打ち込みの深さに応じて、非ねじ軸52hを切断する。
That is, the threaded shaft 52a has two male threads 52m with the non-threaded shaft 52h interposed therebetween.
When using the decorative cap member 51 for the scaffold connecting anchor, the non-threaded shaft 52h is cut according to the driving depth of the scaffold connecting anchor 100.

例えば、図16に示すように、足場つなぎアンカー100の打ち込みが浅いケースでは
、足場つなぎアンカー100の雌ねじ100nが浅い位置にあるので、非ねじ軸52hで切断する。なお、非ねじ軸52hの切断した側に予め面取り52cを付けて、止水ボルト52が足場つなぎアンカー100の雌ねじ100nの内部に入り易くするようにしてもよい。
For example, as shown in FIG. 16, if the scaffolding anchor 100 is driven shallowly
Since the female thread 100n of the scaffold connecting anchor 100 is located at a shallow position, it is cut using the non-threaded shaft 52h. Note that a chamfer 52c may be provided in advance on the cut side of the non-threaded shaft 52h to make it easier for the water stop bolt 52 to enter the inside of the female thread 100n of the scaffold connecting anchor 100.

足場つなぎアンカー100の打ち込みが深いケースでは、雌ねじ100が深い位置にあるので、非ねじ軸52hで切断しない。
変形例4によれば、現場でねじ軸52aの非ねじ軸52hを切断砥石かのこぎりで切断することで、足場つなぎアンカー100にスムーズに挿入できる。
In the case where the scaffold connecting anchor 100 is driven deeply, the female thread 100 is located at a deep position, so it is not cut at the non-threaded shaft 52h.
According to the fourth modification, by cutting the non-threaded shaft 52h of the screw shaft 52a with a cutting grindstone or a saw at the site, it can be smoothly inserted into the scaffold connecting anchor 100.

止水ボルト52は、足場つなぎアンカー100の打ち込み状態に応じて対応できるので、金型や在庫コストを削減できる。
なお、変形例4では、非ねじ軸52hを一つ形成した場合を説明したが、非ねじ軸52hを2つ以上形成してもよい。
Since the water stop bolt 52 can be used depending on the driving state of the scaffold connecting anchor 100, mold and inventory costs can be reduced.
In addition, although the case where one non-threaded shaft 52h was formed in the modification 4 was described, two or more non-threaded shafts 52h may be formed.

<変形例5>
図18に示す変形例5は、化粧キャップ63を止水ボルト62と一体に形成して足場つなぎアンカー用化粧キャップ部61A、61Bを構成したものである。
その他の構成は、実施形態1と同様であるから、同様な構成要素には60番台の符号を付して示し、詳細な説明は省略する。
<Modification 5>
In a fifth modification shown in FIG. 18, a decorative cap 63 is integrally formed with a water stop bolt 62 to constitute decorative cap portions 61A and 61B for scaffold connecting anchors.
Since the other configurations are the same as those of the first embodiment, similar components are designated with numerals in the 60s and detailed explanations are omitted.

変形例5は、化粧キャップ63を止水ボルト62に一体形成して、足場つなぎアンカー用化粧キャップ部62Aを構成した例である。
したがって、部品点数が削減され、組立工程数が削減される。そのため、足場つなぎアンカー用化粧キャップ部62Aの低コスト化が図れる。
Modification 5 is an example in which a decorative cap 63 is integrally formed with a water stop bolt 62 to constitute a decorative cap portion 62A for a scaffold connecting anchor.
Therefore, the number of parts and assembly steps are reduced. Therefore, the cost of the decorative cap portion 62A for the scaffold connecting anchor can be reduced.

図19に示す変形例5の他例は、アンカー用の穴k1の径d1(図11参照)より大きな外径d2をもつツバ部62cと化粧キャップ63とを止水ボルト62に一体形成して足場つなぎアンカー用化粧キャップ部62Bを構成した例である。
止水ボルト62は、ねじ頭62bとねじ軸62aとの間に防水用のツバ部62cが一体に形成されている。
ツバ部62cは、足場つなぎアンカー用の穴k1の径d1(図11参照)より大きな外径d2を有して覆う外周部62c1が形成されている。
Another example of modification 5 shown in FIG. 19 is that a collar portion 62c having an outer diameter d2 larger than the diameter d1 of the anchor hole k1 (see FIG. 11) and a decorative cap 63 are integrally formed on the water stop bolt 62. This is an example of a decorative cap portion 62B for a scaffold connecting anchor.
The water stop bolt 62 has a waterproof collar 62c integrally formed between a screw head 62b and a screw shaft 62a.
The collar portion 62c is formed with an outer circumferential portion 62c1 having an outer diameter d2 larger than the diameter d1 (see FIG. 11) of the hole k1 for the scaffold connecting anchor.

変形例5の他例の足場つなぎアンカー用化粧キャップ部62Bによれば、化粧キャップ63とツバ部62cとを止水ボルト62に一体形成したので、部品点数がさらに削減される。また、さらに組立工程数が削減される。
したがって、低コストの足場つなぎアンカー用化粧キャップ部材62A、62Bを得られる。
According to the decorative cap part 62B for a scaffold connecting anchor of the fifth modification, the decorative cap 63 and the brim part 62c are integrally formed on the water stop bolt 62, so that the number of parts can be further reduced. Furthermore, the number of assembly steps is further reduced.
Therefore, it is possible to obtain decorative cap members 62A and 62B for scaffold connecting anchors at low cost.

<変形例6>
変形例6の足場つなぎアンカー用化粧キャップ部材71(図20参照)は、化粧キャップ73が止水ボルト42に対して柔軟に曲げられる構成である。
その他の構成は実施形態4と同様であるので、同様な構成要素には同一の符号を付して示し詳細な説明は省略する。
<Modification 6>
A decorative cap member 71 for a scaffold connecting anchor according to modification 6 (see FIG. 20) has a configuration in which a decorative cap 73 can be flexibly bent with respect to the water stop bolt 42.
Since the other configurations are the same as those of the fourth embodiment, similar components are denoted by the same reference numerals and detailed explanations will be omitted.

変形例6の足場つなぎアンカー用化粧キャップ部材71は、ゴムパッキン4が嵌められた止水ボルト42のキャップ穴に化粧キャップ73が嵌入されている。ねじ軸42aの先端部42a1から一対の案内突出片42tが突出して、形成されている。 In a decorative cap member 71 for a scaffold connecting anchor according to modification 6, a decorative cap 73 is fitted into a cap hole of a water stop bolt 42 into which a rubber packing 4 is fitted. A pair of guide protruding pieces 42t are formed to protrude from the tip 42a1 of the screw shaft 42a.

化粧キャップ73は、図21にも示すように、キャップ部73aと支持軸部73bとが樹脂または金属を用いて一体に形成されている。
支持軸部73bの根元部73b1は、キャップ部73aに近付くにつれて細く形成され、キャップ部73aに屈曲自在になるよう構成されている。
これにより、図20に示すように、足場つなぎアンカー用化粧キャップ部材71を外壁Kの足場つなぎアンカー100の内部に打ち込んだ際に傾斜していても化粧キャップ73のキャップ部73aの外面73a1が外壁Kの外面Kgに沿わせることができる。
As shown in FIG. 21, the decorative cap 73 has a cap portion 73a and a support shaft portion 73b integrally formed using resin or metal.
The root portion 73b1 of the support shaft portion 73b is formed to become thinner as it approaches the cap portion 73a, and is configured to be bendable toward the cap portion 73a.
As a result, as shown in FIG. 20, even if the decorative cap member 71 for the scaffold connecting anchor is tilted when driven into the inside of the scaffold connecting anchor 100 of the outer wall K, the outer surface 73a1 of the cap portion 73a of the decorative cap 73 is attached to the outer wall K.

<変形例7>
変形例7の足場つなぎアンカー用化粧キャップ部材91(図22(b)参照)は、変形例6の変更タイプである。
図22(a)に示すように、変形例7の化粧キャップ93は、キャップ部93aと支持軸部93bとを有している。
<Modification 7>
A decorative cap member 91 for a scaffold connecting anchor (see FIG. 22(b)) of Modification Example 7 is a modification type of Modification Example 6.
As shown in FIG. 22(a), the cosmetic cap 93 of Modification 7 includes a cap portion 93a and a support shaft portion 93b.

支持軸部93bは、耐候性樹脂で成形される。支持軸部93bは、球部93b1と円柱状の軸部93b2、および球部93b1と軸部93b2とを接続する細い接続部93b3が形成されている。接続部93b3は軸部93b2から球部93b1に近づくに従い次第に細い径となる形状をもつ。
キャップ部93aは、金属製または樹脂製の円板状の部材である。キャップ部93aは、円板状の外板93a1と外板93a1より径が小さく厚い接続板93a2とが形成されている。接続板93a2には、支持軸部93bの球部93b1がインサート成形される。
The support shaft portion 93b is molded from weather-resistant resin. The support shaft portion 93b is formed with a spherical portion 93b1, a cylindrical shaft portion 93b2, and a thin connecting portion 93b3 that connects the spherical portion 93b1 and the shaft portion 93b2. The connecting portion 93b3 has a shape that gradually becomes smaller in diameter as it approaches the spherical portion 93b1 from the shaft portion 93b2.
The cap portion 93a is a disc-shaped member made of metal or resin. The cap portion 93a includes a disk-shaped outer plate 93a1 and a connecting plate 93a2 that is smaller in diameter and thicker than the outer plate 93a1. A spherical portion 93b1 of the support shaft portion 93b is insert molded into the connection plate 93a2.

図22(b)に、足場つなぎアンカー用化粧キャップ部材91が外壁Kの外面Kgに垂直な方向に対して10°の角度で打ち込んだ足場つなぎアンカー100に設置された状態を一例として示す。
図23(a)に、現状品である他社製品の化粧キャップ193の一例の正面断面図を示し、図23(b)に、現状品である他社製品の足場つなぎアンカー用化粧キャップ部材191が足場つなぎアンカー100の内部に設置された状態の一例の断面図を示す。
FIG. 22(b) shows, as an example, a state in which a decorative cap member 91 for a scaffolding tethering anchor is installed on a scaffolding tethering anchor 100 driven at an angle of 10° to the direction perpendicular to the outer surface Kg of the outer wall K.
FIG. 23(a) shows a front cross-sectional view of an example of a cosmetic cap 193 manufactured by another company, which is the current product, and FIG. A sectional view of an example of a state installed inside the tether anchor 100 is shown.

化粧キャップ193は、キャップ部193aと支持軸部193bとを有している。
キャップ部193aは金属製である。キャップ部193aは円板部193a1と球部193a2とが細い金属軸193a3で接続されている。
支持軸部193bは樹脂製の略円柱状の部材である。支持軸部193bにはスリット193b1が形成される。支持軸部193bにはキャップ部193aの球部193a2がインサート成形される。
The decorative cap 193 has a cap portion 193a and a support shaft portion 193b.
The cap portion 193a is made of metal. In the cap portion 193a, a disk portion 193a1 and a spherical portion 193a2 are connected by a thin metal shaft 193a3.
The support shaft portion 193b is a substantially cylindrical member made of resin. A slit 193b1 is formed in the support shaft portion 193b. The spherical portion 193a2 of the cap portion 193a is insert molded into the support shaft portion 193b.

化粧キャップ193は球体である球部193a2の位置がキャップ部193aの表面から離れている。例えば、図23(a)に示すように、化粧キャップ193の支持軸部193bの軸方向の長さs11=3.95mm。そのため、化粧キャップ193の打ち込み後に、アンカー用の穴k1とキャップ部193aとの間の隙間s12が例えば0.84mmとなる。 In the decorative cap 193, a spherical portion 193a2 is located away from the surface of the cap portion 193a. For example, as shown in FIG. 23(a), the axial length s11 of the support shaft portion 193b of the cosmetic cap 193 is 3.95 mm. Therefore, after the decorative cap 193 is driven in, the gap s12 between the anchor hole k1 and the cap portion 193a is, for example, 0.84 mm.

これに対して、図22(a)に示す変形例7の化粧キャップ93は、球体である球部93a2の位置がキャップ部93aの表面から近い。例えば化粧キャップ93の支持軸部93bの軸方向の長さs1=1.8mm。そのため、化粧キャップ93の打ち込み後に、アンカ
ー用の穴k1とキャップ部93aとの間の隙間s2が例えば0.46 mmで済む。
On the other hand, in the cosmetic cap 93 of Modification Example 7 shown in FIG. 22(a), the spherical portion 93a2 is located close to the surface of the cap portion 93a. For example, the axial length s1 of the support shaft portion 93b of the cosmetic cap 93 is 1.8 mm. Therefore, after the decorative cap 93 is driven in, the gap s2 between the anchor hole k1 and the cap portion 93a only needs to be 0.46 mm, for example.

変形例7の化粧キャップ93は、化粧キャップ193と比較し、アンカー用の穴k1とキャップ部93aとの間の隙間s2が約半分に改善されている。
上述の変形例7の化粧キャップ93は前記の変形例6の化粧キャップ73より更に効果が高い。
In the decorative cap 93 of Modification 7, the gap s2 between the anchor hole k1 and the cap portion 93a is reduced by about half compared to the decorative cap 193.
The cosmetic cap 93 of the seventh modification described above is even more effective than the cosmetic cap 73 of the sixth modification.

<<実施形態2>>
図24(a)に示す実施形態2の足場つなぎアンカー用化粧キャップ部材1Aは、実施形態1と変形例1と変形例3とを組み合わせて構成したものである。
図24(b)に示すように、止水ボルト82の雄ねじ82mを、足場つなぎアンカー100の雌ねじ100n(図3(a)参照)と同じピッチでπ位相をずらして形成した第1雄ねじ2m1と第2雄ねじ2m2とで形成している。そして、雄ねじ82mの外周部を雄ねじ頭部82bの側から雄ねじ82mの先端82a1の側まで軸方向に沿って除去された面取り箇所82m1が1箇所以上ある構成としたものである。
<<Embodiment 2>>
A decorative cap member 1A for a scaffold connecting anchor according to Embodiment 2 shown in FIG. 24(a) is constructed by combining Embodiment 1, Modification 1, and Modification 3.
As shown in FIG. 24(b), the male thread 82m of the water stop bolt 82 is formed with a first male thread 2m1 formed by shifting the phase by π at the same pitch as the female thread 100n of the scaffolding anchor 100 (see FIG. 3(a)). It is formed with a second male screw of 2m2. The outer peripheral portion of the male screw 82m is configured to have one or more chamfered portions 82m1 removed along the axial direction from the side of the male screw head 82b to the side of the tip 82a1 of the male screw 82m.

図24(a)~(c)では面取り箇所82m1を4箇所形成した例を示している。止水ボルト82の雄ねじ82mのねじ山の高さは、足場つなぎアンカー100の雌ねじ100nのねじ山の高さより低く形成されている。
ねじ軸82aの先端部82a1から案内突出片82tを突出して一対形成している。
案内突出片82tは、長い本体部82t1とテーパ部82t2とを有している。テーパ部82t2は、案内突出片82tの先端部に、先端側にいくほど内側に位置する傾斜を有している。また、案内突出片82tの根元内側には、凹形状の切り込み82t3が形成されている。
FIGS. 24(a) to 24(c) show an example in which four chamfered portions 82m1 are formed. The height of the thread of the male thread 82m of the water stop bolt 82 is formed lower than the height of the thread of the female thread 100n of the scaffold connecting anchor 100.
A pair of guide protruding pieces 82t are formed by protruding from the tip 82a1 of the screw shaft 82a.
The guide projection piece 82t has a long main body portion 82t1 and a tapered portion 82t2. The tapered portion 82t2 has a slope at the tip of the guide protrusion 82t that is located inward toward the tip. Furthermore, a concave notch 82t3 is formed inside the base of the guide protrusion 82t.

実施形態2によれば、雄ねじ82mの外周部がねじ頭部82bの側から雄ねじ82mの先端82a1の側まで軸方向に沿って除去された面取り箇所82m1が形成されているので、よりスムーズに壁Kのアンカー用の穴k1に打ち込む(嵌合する)ことができる。
また、止水ボルト82の雄ねじ82mに面取り箇所82m1を有する。そのため、足場つなぎアンカー100の内部に足場つなぎアンカー用化粧キャップ部材1Aを打ち込む際に、足場つなぎアンカー100の雌ねじ100nと、足場つなぎアンカー用化粧キャップ部材1Aの雄ねじ82mとの軸方向の重畳面積が減るので、円滑かつ容易に打ち込める。
According to the second embodiment, the chamfered portion 82m1 is formed by removing the outer peripheral portion of the male screw 82m along the axial direction from the side of the screw head 82b to the side of the tip 82a1 of the male screw 82m, so that the wall can be attached more smoothly. It can be driven (fitted) into the anchor hole k1 of K.
Further, the male thread 82m of the water stop bolt 82 has a chamfered portion 82m1. Therefore, when driving the decorative cap member 1A for the scaffold connecting anchor 100, the axial overlapping area of the female thread 100n of the scaffold connecting anchor 100 and the male thread 82m of the decorative cap member 1A for the scaffold connecting anchor is This reduces the amount of time required, so you can type smoothly and easily.

また、止水ボルト82は先端にテーパ部82t2と凹形状の切り込み82t3とを有する案内突出片82tを備えるので、足場つなぎアンカー100の内部に足場つなぎアンカー用化粧キャップ部材1Aを打ち込む際に案内突出片82tに案内させて円滑に打ち込むことができる。 なお、止水ボルト82の雄ねじ82mは、足場つなぎアンカー100の雌ねじ100nの1/2ピッチのピッチp2の雄ねじ2m3で構成してもよい。 Moreover, since the water stop bolt 82 is equipped with a guide protrusion piece 82t having a tapered part 82t2 and a concave cut 82t3 at the tip, the guide protrusion when driving the decorative cap member 1A for the scaffold linking anchor into the inside of the scaffold linking anchor 100. It can be driven smoothly by being guided by the piece 82t. The male screw 82m of the water stop bolt 82 may be configured with a male screw 2m3 having a pitch p2 that is 1/2 the pitch of the female screw 100n of the scaffolding anchor 100.

<変形例8>
変形例8の化粧キャップ113は、変形例6の化粧キャップ73の変更タイプである。
図25に示すように、変形例8の化粧キャップ113は、キャップ部113aと支持軸部113bとが樹脂または金属を用いて一体に形成されている。

A small diameter portion 113b1, a locking portion 113b2, and an inclined surface portion 113b3 are formed in order from the cap portion 113a side at the root portion of the support shaft portion 113b. The small diameter portion 113b1 is continuous with the center portion of the cap portion 113a, and is formed to be thin so that the cap portion 113a can be freely bent with respect to the support shaft portion 113b.
The locking portion 113b2 includes a protrusion having a larger diameter than the small diameter portion 113b1. The diameter of the protrusion gradually increases from the small diameter portion 113b1 toward the distal end of the support shaft portion 113b, and then slightly decreases in diameter. The protrusion has a triangular cross section and is formed in an annular shape along the circumferential direction.
The inclined surface portion 113b3 gradually expands in diameter as it continues from the distal end of the locking portion 113b2 toward the distal end side of the support shaft portion 113b (away from the cap portion 113a), and is connected to the outer peripheral surface of the support shaft portion 113b. There is.
The cosmetic cap 113 of Modification 8 can be used in place of the makeup cap 3 of Embodiment 1, the makeup cap 73 of Modification 6, and the makeup cap 93 of Modification 7.

このような構造の化粧キャップ113によれば、化粧キャップ113を止水ボルト112に挿入した状態で、万一小径部113b1が破断し、キャップ部113aが外れた場合に、支持軸部113bを取り出すことができる。具体的には、ラジオペンチ等の工具を用いて係止部113b2を挟み込み、引き抜くことで容易に支持軸部113bを取り出すことができる。 According to the decorative cap 113 having such a structure, if the small diameter portion 113b1 breaks and the cap portion 113a comes off while the decorative cap 113 is inserted into the water stop bolt 112, the support shaft portion 113b can be taken out. be able to. Specifically, the support shaft portion 113b can be easily taken out by pinching the locking portion 113b2 using a tool such as radio pliers and pulling it out.

<Modification 9>
The rubber packing 114 of Modification 9 is attached to the water stop bolt in a direction opposite to that of the rubber packing 4 of Embodiment 1. The rubber packing 114 has a cylindrical shape and is fitted in advance to the base of the threaded shaft 112a of the water stop bolt 112. As shown in FIG. 26, the rubber packing 114 has a body portion 114a and a collar portion 114b. The collar portion 114b has an annular portion 114b1 in the shape of a truncated cone whose diameter gradually decreases as it moves away from the body portion 4a. The annular portion 114b1 is formed in a size that allows the rubber packing 114 to smoothly slide and seal the inner peripheral surface of the anchor hole k1 when the decorative cap member 111 for the scaffold connecting anchor is driven in. There is. The rubber packing 114 is fitted to the base of the screw shaft 112a such that the collar portion 114b is located closer to the tip of the screw shaft 112a than the body portion 114a.
The rubber packing 114 of Modification 9 can be used in place of the rubber packing 4 of Embodiment 1 or Embodiment 2, and can be attached to the water stop bolts of Modifications 1 to 5.

このような構成のゴムパッキン114によれば、ゴムパッキン114が装着された止水ボルト112を穴k1に挿入する際に、鍔部114bが穴k1の内周面に引っかからず、円滑に挿入できる。また、鍔部114bは、ねじ頭112bから離れているので、変形し易く、穴k1内を挿通しやすい。 According to the rubber packing 114 having such a configuration, when the water stop bolt 112 with the rubber packing 114 attached thereto is inserted into the hole k1, the collar portion 114b does not get caught on the inner peripheral surface of the hole k1, and the bolt can be inserted smoothly. . Further, since the collar portion 114b is separated from the screw head 112b, it is easily deformed and easily inserted into the hole k1.

<変形例10>
変形例10の止水ボルト112は、ねじ軸112aとねじ頭112bとを備えている。図27および図28に示すように、ねじ軸112aの内側には、棒状のレンチ(図示せず)が挿入されるレンチ穴115が軸方向に延在して設けられている。本変形例のレンチ穴115は、断面多角形状(本変形例10では六角穴形状)を呈しており、六角レンチが挿入される。レンチ穴115は、ねじ頭112bの表面の開口部116から連続している。開口部116は、レンチ穴115の六角穴より大径の円形穴形状を呈している。開口部116の外側端部には、外側に向かって拡径するテーパ部116aが形成されている。レンチ穴115は、化粧キャップ113の支持軸部113bが嵌入されるキャップ穴112b1と兼用されている。レンチ穴115は、支持軸部113bの形状に応じて、軸方向寸法および内径寸法が設定されている。なお、レンチ穴115の形状は、六角に限定されるものではなく、断面多角形状であればよく、レンチの断面形状に合わせて他の多角形や星形等、他の形状であってもよい。なお、星形も多角形に含む。
変形例10の止水ボルト112は、実施形態1の止水ボルト2や実施形態2の止水ボルト82に代えて用いることができる。。
<Modification 10>
The water stop bolt 112 of Modification 10 includes a screw shaft 112a and a screw head 112b. As shown in FIGS. 27 and 28, a wrench hole 115 into which a rod-shaped wrench (not shown) is inserted is provided inside the screw shaft 112a and extends in the axial direction. The wrench hole 115 of this modification has a polygonal cross section (hexagonal hole shape in this modification 10), into which a hexagonal wrench is inserted. The wrench hole 115 is continuous from the opening 116 on the surface of the screw head 112b. The opening 116 has a circular hole shape with a larger diameter than the hexagonal hole of the wrench hole 115. A tapered portion 116a whose diameter increases outward is formed at the outer end of the opening 116. The wrench hole 115 also serves as a cap hole 112b1 into which the support shaft portion 113b of the decorative cap 113 is inserted. The wrench hole 115 has an axial dimension and an inner diameter dimension set according to the shape of the support shaft portion 113b. Note that the shape of the wrench hole 115 is not limited to a hexagonal shape, but may have a polygonal cross-section, and may have other shapes such as another polygon or a star shape depending on the cross-sectional shape of the wrench. . Note that star shapes are also included in polygons.
The water stop bolt 112 of Modification 10 can be used in place of the water stop bolt 2 of Embodiment 1 and the water stop bolt 82 of Embodiment 2. .

このような構成の止水ボルト112によれば、ねじ頭112bにボックスレンチを嵌めて止水ボルト112を着脱する場合と比較して、ねじ頭112bの軸方向長さを短くすることができる。これによって、化粧キャップ113と穴k1の隙間から浸入する雨水が溜まるエリアを小さくすることができる。また、レンチ穴115の軸方向寸法を十分に確保できるので、確実に止水ボルト112を回転することができる。 According to the water stop bolt 112 having such a configuration, the axial length of the screw head 112b can be shortened compared to the case where the water stop bolt 112 is attached and detached by fitting a box wrench into the screw head 112b. Thereby, it is possible to reduce the area where rainwater that enters through the gap between the decorative cap 113 and the hole k1 accumulates. Moreover, since the axial dimension of the wrench hole 115 can be ensured sufficiently, the water stop bolt 112 can be rotated reliably.

<<実施形態3>>
図29に示す実施形態3の足場つなぎアンカー用化粧キャップ部材111は、実施形態1と変形例8と変形例9と変形例10とを組み合わせて構成したものである。実施形態3のアンカー用化粧キャップ部材111は、止水ボルト112に挿入された化粧キャップ113の形状と、止水ボルト112のねじ軸112aの根元に嵌められたゴムパッキン114の形状と止水ボルト112の形状が実施形態1と異なる。また、止水ボルト112には、ねじ軸112aの先端部112a1から一対の案内突出部112tが突出して形成されている。
その他の構成は実施形態1と同様であるので、同様な構成要素には同一の符号を付して示し詳細な説明は省略する。
<<Embodiment 3>>
A decorative cap member 111 for a scaffold connecting anchor according to Embodiment 3 shown in FIG. 29 is constructed by combining Embodiment 1, Modification 8, Modification 9, and Modification 10. The anchor decorative cap member 111 of the third embodiment has the shape of the decorative cap 113 inserted into the water stop bolt 112, the shape of the rubber packing 114 fitted to the root of the threaded shaft 112a of the water stop bolt 112, and the water stop bolt. The shape of 112 is different from the first embodiment. Further, the water stop bolt 112 is formed with a pair of guide protrusions 112t that protrude from the tip 112a1 of the screw shaft 112a.
Since the other configurations are the same as those of the first embodiment, similar components are denoted by the same reference numerals and detailed explanations will be omitted.

本実施形態の止水ボルト112は、六角レンチを用いて、足場つなぎアンカー100の雌ねじ100nに螺合される。アンカー用化粧キャップ部材111の止水ボルト112のキャップ穴112b1には、変形例8の化粧キャップ113の支持軸部113bが嵌入されている。止水ボルト112のねじ軸112aの根元には、変形例9のゴムパッキン114が嵌合されている。ゴムパッキン4は、鍔部114bが胴部114aよりもねじ軸112aの先端側に位置するように、ねじ軸112aの根元に嵌められている。 The water stop bolt 112 of this embodiment is screwed into the female thread 100n of the scaffolding anchor 100 using a hexagonal wrench. The support shaft portion 113b of the decorative cap 113 of Modification 8 is fitted into the cap hole 112b1 of the water stop bolt 112 of the decorative anchor cap member 111. A rubber packing 114 according to modification 9 is fitted to the base of the threaded shaft 112a of the water stop bolt 112. The rubber packing 4 is fitted onto the base of the screw shaft 112a such that the collar portion 114b is located closer to the tip of the screw shaft 112a than the body portion 114a.

実施形態3によれば、化粧キャップ113を傾斜させる際に、万一小径部113b1が破断しキャップ部113aが外れたとしても、ラジオペンチ等の工具で係止部113b2を挟み込み、引き抜くことで容易に支持軸部113bを取り出すことができる。
また、ゴムパッキン114の鍔部114bが挿入方向の先端側が小径の円錐状部114b1を備えているので、止水ボルト112を穴k1に挿入する際に、ゴムパッキン114の鍔部114bが穴k1の内周面に引っかからず、止水ボルト112を円滑に挿入することができる。また、鍔部114bは、ねじ頭112bから離れているので、変形し易く、止水ボルト112は穴k1内をより一層挿入しやすい。
According to the third embodiment, even if the small diameter portion 113b1 breaks and the cap portion 113a comes off when tilting the cosmetic cap 113, it can be easily removed by pinching the locking portion 113b2 with a tool such as radio pliers and pulling it out. The support shaft portion 113b can be taken out.
Further, since the flange 114b of the rubber packing 114 has a conical portion 114b1 having a small diameter on the distal end side in the insertion direction, when the water stop bolt 112 is inserted into the hole k1, the flange 114b of the rubber packing 114 is inserted into the hole k1. The water stop bolt 112 can be inserted smoothly without getting caught on the inner circumferential surface of the water stop bolt 112. Further, since the collar portion 114b is separated from the screw head 112b, it is easily deformed, and the water stop bolt 112 is easier to insert into the hole k1.

さらに、止水ボルト112は、ねじ軸112aの内側にレンチ穴115が形成されているので、ねじ頭112bにボックスレンチを嵌めて止水ボルト112を着脱する場合と比較して、ねじ頭112bの軸方向長さを短くすることができる。よって、化粧キャップ113と穴k1の隙間から浸入する雨水が溜まるエリアを小さくすることができる。さらに、一旦足場つなぎアンカー100に装着した止水ボルト112は、化粧キャップ113を取り外した後に、レンチ穴115にレンチを挿入して回転させることで、取り外すことができる。 Furthermore, since the water stop bolt 112 has a wrench hole 115 formed inside the screw shaft 112a, the water stop bolt 112 can be attached or removed by fitting a box wrench into the screw head 112b. The axial length can be shortened. Therefore, the area where rainwater that enters through the gap between the decorative cap 113 and the hole k1 accumulates can be reduced. Further, the water stop bolt 112 once attached to the scaffold connecting anchor 100 can be removed by removing the decorative cap 113 and then inserting a wrench into the wrench hole 115 and rotating it.
