らず、組立や荷揚などの高所作業による危険があり、墜
落事故などの発生の恐れも多い。Traditionally, this kind of scaffolding was constructed by setting up gate-shaped scaffolding frames on the ground, reinforcing them with diagonal braces, and placing a top plate (fabric frame) on top. To put it on,
The construction is repeated horizontally and upwardly until a predetermined height is reached.During assembly, the working position gradually becomes higher, while during disassembly, it must be dismantled sequentially from the top, increasing the height of assembly and unloading. There are dangers associated with the work, and there is a high risk of accidents such as falls.
そこで、これら足場枠の組立及び解体を地上で出来るよ
うにした工法が提案されており、クレーン等を用いて吊

になるようにし、吊上げ時の揺れを防止する。Wire guides 15 are placed on both sides of the first stage scaffolding frame 7.
is attached so that the scaffold frame 7 can slide along the guide wire 4 and prevent shaking during lifting.
（３）こののち、フレーム６をワインダ１０を操作する
ことによって下降させ、伸縮式連結部材８によって第１
段目の足場枠７と連結する。(3) After that, the frame 6 is lowered by operating the winder 10, and the telescopic connecting member 8
It is connected to the scaffolding frame 7 of the second stage.

結ができるのである。By connecting these temporary connections and permanent connections separately,
Only by lowering the frame 6 by the winder 10, the connecting portion 6a
, 7a, it is not necessary to align the position accurately, and it is only necessary to align the position up and down within the range of expansion and contraction of the telescoping connecting member 8, and the guide wire 4 can also sway from side to side.
Therefore, it is possible to easily connect a large number of connecting portions 7a.
（４）次に、第２図に示すように、フレーム６に本結合
された足場枠７を１段の足場枠７より高い位置まで吊り
上げた状態に保持し、再び地上のジヤツキプレート１２
上で次段（２段目）の足場枠７を組立てる。(4) Next, as shown in FIG. 2, the scaffolding frame 7 that has been fully connected to the frame 6 is held in a suspended state higher than the first stage of the scaffolding frame 7, and the jack plate 12 on the ground is again
Assemble the next (second stage) scaffolding frame 7 above.
組立完了後、ワイヤガイド１５を取り付けて足場枠７を
ガイドワイヤ４に沿って昇降できるようにし、フレーム

, 7 are concatenated. In this case, the connection method is similar to the connection between the frame 6 and the scaffolding frame 7, so that the temporary connection and the final connection are performed separately to facilitate positioning.
（５）こうして第３図に示すように、第３段目の足場枠
７を地上で組立てるなど、組立と吊上げを繰り返して必
要な段数の足場枠７をフレーム６の下側に連結した後、
ジヤツキプレート１２上に載置する。(5) As shown in FIG. 3, after assembling and lifting the third stage scaffolding frame 7 on the ground, and repeating the assembly and lifting, the required number of stages of scaffolding frame 7 are connected to the lower side of the frame 6.
Place it on the jack plate 12.
そして、必要箇所に壁つなぎを設けて建物１と連結し、
足場の構築が完了する。Then, connect it to Building 1 by installing wall connections in the necessary places,
Construction of scaffolding is completed.
さらに、必要に応じて、吊上げ用ワイヤ９を外しなり、
ガイドワイヤ４を収り外すようにするが、転倒防止や解
体作業のなめそのままにしておくようにしても良い。Furthermore, if necessary, remove the lifting wire 9,
Although the guide wire 4 is designed to be removed, it may be left as is to prevent it from falling over or for disassembly work.
また、建物１への入口などを設ける必要かある場合には

ようにして形成する。In addition, if it is necessary to provide an entrance to the building 1, etc., the scaffolding frame 7 may be formed by removing a portion of the scaffolding frame 7 while it is in a suspended state or after it has been completely lowered, or by removing the entire scaffolding frame 7 while it is in a suspended state. If the scaffolding frame is to be left as it is, the scaffolding frame is fixed to the building 1 etc. without providing the lowest scaffolding frame.
（Ｂ） 足場の解体方法については、組立の場合と逆
の工程にしたがって行われるので、詳細な説明は省略す
る。(B) The method for dismantling the scaffolding is carried out in the reverse order of the assembly process, so a detailed explanation will be omitted.
この解体においても、フレーム６を設置するとともに、
ガイドワイヤ４及びワイヤガイド１５を用いて揺れを防
止する。In this disassembly, as well as installing the frame 6,
Shaking is prevented using the guide wire 4 and wire guide 15.
また、足場枠７．７同志の連結部７ａ及び足場枠７とフ
レーム６との連結部６ａ、７ａに伸縮式連結部材８が用
いられているので、解体を簡単に行うことができる。Moreover, since the telescopic connecting members 8 are used for the connecting parts 7a between the scaffold frames 7 and 7 and the connecting parts 6a and 7a between the scaffold frames 7 and the frames 6, disassembly can be easily performed.
このような足場の組立て及び解体方法によれば、はとん
どの作業を地上で行うことができ、危険な高所作業がな
くなり作業の安全性が向上する。According to such a method for assembling and dismantling a scaffold, most of the work can be done on the ground, eliminating dangerous work at heights and improving work safety.
また、地上での作業であるため、作業能率が向上する。Additionally, since the work is done on the ground, work efficiency is improved.
さらに、従来の足場枠に対して伸縮式連結部材を装着す
