この落下防止板部材取り付け用治具Ｊは、全体としてＵ字形状を呈する抱持部材Ｊｈと、
抱持部材Ｊｈの各遊端部に、その延長方向に延びるように一体的に連結された固定部材Ｊｆと、抱持部材Ｊｈの一方の遊端寄り所定位置に回転可能に連結され、かつ抱持部材Ｊｈの他方の遊端寄り所定位置に係脱可能に係合される状態選択部材Ｊｓとを有している。
固定部材Ｊｆは、抱持部材Ｊｈの延長方向に延びる主体部Ｊｆ１と、主体部Ｊｆ１の所定位置から下向きに延びる３本の挟み込み用棒状部材Ｊｆ２とを有している。したがって、隣り合う１対の挟み込み用棒状部材Ｊｆ２によって、落下防止板部材（幅木、抜き板等）ｒｐを挟み込んで固定することができる。
This fall prevention plate member mounting jig J has a U-shaped holding member Jh as a whole,
A fixed member Jf that is integrally connected to each free end of the holding member Jh so as to extend in the extending direction thereof, and is rotatably connected to a predetermined position near one free end of the holding member Jh. And a state selection member Js that is detachably engaged with a predetermined position near the other free end of the holding member Jh.
The fixing member Jf has a main body portion Jf1 extending in the extending direction of the holding member Jh, and three sandwiching bar members Jf2 extending downward from a predetermined position of the main body portion Jf1. Accordingly, the fall prevention plate member (baseboard, punched plate, etc.) rp can be sandwiched and fixed by the pair of adjacent sandwiching bar members Jf2.
状態選択部材Ｊｓは、抱持部材Ｊｈの一方の遊端寄り所定位置に回転可能に連結され、かつ外形が六角柱形状を有する回転部材Ｊｓ１と、抱持部材Ｊｈの遊端部と直交する方向に延びる回転腕部材Ｊｓ２と、回転腕部材Ｊｓ２の先端部を折り曲げ状に形成することによって抱持部材Ｊｈの他方の遊端寄り所定位置に係脱可能に係合される係合部材Ｊｓ３とを有している。
ここで、回転部材Ｊｓ１として六角柱形状のナットを採用することが可能である。
The state selection member Js is rotatably connected to a predetermined position near one free end of the holding member Jh, and the outer shape has a hexagonal column shape, and a direction orthogonal to the free end portion of the holding member Jh. A rotating arm member Js2 extending in the direction of the other end, and an engaging member Js3 that is detachably engaged with a predetermined position near the other free end of the holding member Jh by forming the distal end portion of the rotating arm member Js2 in a bent shape. Have.
Here, a hexagonal column-shaped nut can be employed as the rotating member Js1.
次いで、図４を参照して、落下防止板部材取り付け用治具Ｊによる落下防止板部材ｒｐの固定作業を説明する。
先ず、係合部材Ｊｓ３が抱持部材Ｊｈの他方の遊端寄り所定位置から係脱するように回転腕部材Ｊｓ２を回動させ、抱持部材Ｊｈの遊端部同士の間を大きく開放しておく。
この状態で、足場建地ａｔが固定部材Ｊｆ同士の間を通り、さらに抱持部材Ｊｈの遊端部同士の間を通り、抱持部材Ｊｈの内奥部に抱持されるように、抱持部材Ｊｈを水平方向に移動させる。
なお、この作業を行う場合には、抱持部材Ｊｈの上下方向の位置は、足場板ａｐの端縁部に対応させて支持された落下防止板部材ｒｐよりも上方となるように設定される。ここで、足場板ａｐは、間接的に足場建地ａｔにより支持されている。具体的には、足場建地ａｐ同士を連結する連結部材ｒｍにより支持されている。ただし、足場板ａｐは、直接的に足場建地ａｔにより支持されていてもよい。
Next, with reference to FIG. 4, the fixing operation of the fall prevention plate member rp by the fall prevention plate member attaching jig J will be described.
First, the rotary arm member Js2 is rotated so that the engaging member Js3 is engaged and disengaged from the predetermined position near the other free end of the holding member Jh, and the free end portions of the holding member Jh are largely opened. deep.
In this state, the scaffold building at is passed between the fixing members Jf, further passed between the free ends of the holding member Jh, and held in the inner back of the holding member Jh. The holding member Jh is moved in the horizontal direction.
When this operation is performed, the vertical position of the holding member Jh is set to be higher than the fall prevention plate member rp supported corresponding to the end edge of the scaffold plate ap. . Here, the scaffold plate ap is indirectly supported by the scaffold building at. Specifically, it is supported by a connecting member rm that connects the scaffolding ap. However, the scaffold plate ap may be directly supported by the scaffold building at.
その後、１対の固定部材Ｊｆが落下防止板部材ｒｐの直上に位置するように抱持部材Ｊｈを、足場建地ａｔを基準として回転させ、次いで、抱持部材Ｊｈを下降させることにより、両固定部材Ｊｆの隣り合う１対の挟み込み用棒状部材Ｊｆ２によって、落下防止板部材ｒｐを挟み込んで固定することができる。ここで、落下防止板部材ｒｐは、連結部材ｒｍにより支持されているが、足場板ａｐの端縁部に直接に支持されていてもよい。
そして、係合部材Ｊｓ３が抱持部材Ｊｈの他方の遊端寄り所定位置と係合するように回転腕部材Ｊｓ２を回動させ、抱持部材Ｊｈの遊端部同士の間を閉じる。
この状態においては、足場建地ａｔが抱持部材Ｊｈ及び状態選択部材Ｊｓによって抱持された状態となるので、落下防止板部材取り付け用治具Ｊが足場建地ａｔに対して水平方向にスライドして位置ずれすることがなくなる。
Thereafter, the holding member Jh is rotated with reference to the scaffold building at so that the pair of fixing members Jf are positioned immediately above the fall prevention plate member rp, and then the holding member Jh is lowered to The fall prevention plate member rp can be sandwiched and fixed by a pair of sandwiching rod members Jf2 adjacent to the fixing member Jf. Here, the fall prevention plate member rp is supported by the connecting member rm, but may be directly supported by the end edge portion of the scaffold plate ap.
Then, the rotary arm member Js2 is rotated so that the engaging member Js3 engages with the predetermined position near the other free end of the holding member Jh, and the gap between the free ends of the holding member Jh is closed.
In this state, since the scaffold building area at is held by the holding member Jh and the state selection member Js, the fall prevention plate member mounting jig J slides horizontally with respect to the scaffold building area at. As a result, the position is not displaced.
そして、１対の固定部材Ｊｆの、それぞれの隣り合う１対の挟み込み用棒状部材Ｊｆ２によって、落下防止板部材ｒｐを挟み込んで固定しているので、結果的に、落下防止板部材ｒｐを足場建地ａｔに対して固定することが可能となる。
なお、以上の説明は、１本の足場建地ａｔについてのものであるから、落下防止板部材取り付け用治具Ｊが足場建地ａｔを基準として回転すると思われるかもしれない。しかし、実際の足場においては、足場建地ａｔは複数本存在し、各足場建地ａｔに対して落下防止板部材取り付け用治具Ｊが装着され、２つ以上の落下防止板部材取り付け用治具Ｊによって落下防止板部材ｒｐを挟み込んで固定するのであるから、落下防止板部材取り付け用治具Ｊが回転するおそれは全くない。
したがって、簡単な作業で、落下防止板部材ｒｐを確実に固定することができる。
また、足場を解体する場合には、上記と逆の作業を行うことによって、落下防止板部材ｒｐの固定を解除することができる。
上記の構成の落下防止板部材取り付け用治具において、構成各部のサイズは全く言及していないが、適用される足場の各部の寸法に合わせて最適なサイズに設定することはもちろんである。
Since the fall prevention plate member rp is sandwiched and fixed by the adjacent pair of sandwiching rod members Jf2 of the pair of fixing members Jf, as a result, the fall prevention plate member rp is fixed to the scaffolding. It becomes possible to fix to the ground at.
In addition, since the above description is about one scaffold building at, it may be thought that the fall prevention board member attachment jig J rotates with respect to the scaffold building at. However, in an actual scaffold, there are a plurality of scaffold building sites at, and a jig J for attaching a fall prevention plate member is mounted on each scaffold building at and two or more fall prevention plate member installation jigs are installed. Since the fall prevention plate member rp is sandwiched and fixed by the tool J, there is no possibility that the fall prevention plate member attaching jig J rotates.
Therefore, the fall prevention plate member rp can be reliably fixed by a simple operation.
Further, when the scaffold is dismantled, the fall prevention plate member rp can be released by performing the reverse operation to the above.
In the fall prevention plate member mounting jig having the above-described configuration, the size of each component is not mentioned at all, but it is a matter of course that the optimum size is set in accordance with the size of each component of the scaffold to be applied.
