Then, it is made to be level with the previous frame member 2, and is finally tightened (mainly fixed) in a horizontal state, the height adjustment by the hanging member 5 is performed, and the frame members 2 are sequentially connected repeatedly. A suspended scaffold can be formed.

なお、枠部材２の係止部材６は、筒状の長辺部11にしか設けられていないため、１つ目の枠部材２を設置する際には、４点吊りができない。そこで、本実施例においては、１つ目の枠部材２には、別途補助具19を取り付け、この補助具19に設けた係止部材６と枠部材２の係止部材６とで４点吊りができるように構成している。 Since the locking member 6 of the frame member 2 is provided only on the cylindrical long side portion 11, when the first frame member 2 is installed, it cannot be suspended at four points. Therefore, in the present embodiment, an auxiliary tool 19 is separately attached to the first frame member 2 and is suspended at four points by the locking member 6 provided on the auxiliary tool 19 and the locking member 6 of the frame member 2. It is configured to be able to.

補助具19は、図１０に図示したように、（後述する受け板50を除き）枠部材２の前記筒状の長辺部11と同構成の長尺体（長物状）である。即ち、筒状の長辺部11と同様に、補助具19は角筒状であり、両端部に夫々螺合部材保持体９が挿抜自在に設けられ、各螺合部材８と連通する挿通孔51が上面に並設されている。また、一端側には上記同様のクランプ部４（単管クランプ52及び基体53）が設けられており、クランプ部４で枠部材２の棒状の長辺部12をクランプすることで枠部材２に取り付けることができる。また、上記同様の取付部20，21が一端側及び他端側に設けられている。 As illustrated in FIG. 10, the auxiliary tool 19 is a long body (long object shape) having the same configuration as the cylindrical long side portion 11 of the frame member 2 (except for a receiving plate 50 described later). That is, like the cylindrical long side portion 11, the auxiliary tool 19 has a rectangular tube shape, and the screw member holding bodies 9 are detachably provided at both ends, and the insertion holes communicate with the screw members 8. 51 are arranged on the upper surface. Further, a clamp portion 4 (single tube clamp 52 and base 53) similar to the above is provided on one end side, and the rod-like long side portion 12 of the frame member 2 is clamped by the clamp portion 4 to the frame member 2. Can be attached. Further, the same mounting portions 20 and 21 as described above are provided on one end side and the other end side.

なお、補助具19は、１つ目の枠部材２を設置する場合に限らず、枠部材２を途中まで並設した後、これまでの並設部分とは縁を切り、例えば並設方向を変えたい場合にも同様にして用いることができる。従って、補助具19を用いることで、直線状に限らず、曲線状に枠部材２を並設することもできる。 The auxiliary tool 19 is not limited to the case where the first frame member 2 is installed, and after the frame member 2 is juxtaposed halfway, the edge is separated from the conventional juxtaposed portion, for example, the juxtaposition direction is changed. It can also be used in the same way when changing. Therefore, by using the auxiliary tool 19, the frame members 2 can be arranged side by side not only in a straight line but also in a curved line.

本実施例は上述のように構成したから、枠部材２同士を連結して吊足場を形成する際、吊下部材５の間隔に応じ、係止部材６の螺子部７を螺入する螺合部材８を適宜選択できるから、吊下部材５が可及的に垂直に近い状態となり、安定的な吊足場を形成できる。 Since the present embodiment is configured as described above, when the frame members 2 are connected to each other to form a suspended scaffolding, the threaded portion 7 is screwed into the threaded portion 7 of the locking member 6 according to the interval of the suspended member 5. Since the member 8 can be selected as appropriate, the suspension member 5 is as close to vertical as possible, and a stable suspension scaffold can be formed.

即ち、係止部材６を取り付ける螺合部材８の位置を選択して吊下部材５が可及的に垂直に近い形で枠部材２を吊下げることが可能となり、強固に且つ安定的に枠部材２を吊下げることが可能となる。 That is, the position of the screwing member 8 to which the locking member 6 is attached can be selected to suspend the frame member 2 so that the suspension member 5 is as vertical as possible. The member 2 can be suspended.

また、係止部材６の螺子部７と螺合する螺合部材８は、螺合部材保持体を枠部材２から抜き出すことで容易に交換でき、経時劣化による破損等を防止しつつ螺合部材以外を繰り返し使用することが可能となる。 Further, the screwing member 8 to be screwed with the screw part 7 of the locking member 6 can be easily replaced by extracting the screwing member holding body from the frame member 2, and prevents the damage due to deterioration over time, etc. It is possible to repeatedly use other than the above.

よって、本実施例は、長手方向両端部の係止部材の位置を吊下部材の間隔に合わせて変えることができ、また、係止部材が取り付けられる螺合部材の交換を容易に行うことができる等、より取り扱い易い実用性に秀れたものとなる。 Therefore, in this embodiment, the positions of the locking members at both ends in the longitudinal direction can be changed according to the interval of the suspension members, and the screwing member to which the locking members are attached can be easily replaced. It can be easily handled and has excellent utility.
