Description

本発明は、工事現場や山等の法面における作業、例えば、宅地の造成や高速道路の施工、治山事業工事等を行う際に、作業工具や資材等の仮置き場等として用いる法面用の仮設足場及びその設置方法に関する。   The present invention is intended for use as a temporary storage place for working tools, materials, etc. when performing work on a slope such as a construction site or mountain, for example, construction of a residential land, construction of a highway, construction of a forestry project, etc. The present invention relates to a temporary scaffold and its installation method.

従来、山等を切り拓いて宅地の造成や高速道路等を施工する際に形成される法面において土木作業者等が作業を行うにあたり、例えば、法面上方より適宜長さのワイヤーロープ等で前記作業者を吊り下げて支持し、作業者はその状態でワイヤーロープを伝って、或いはウインチ等でワイヤーロープを繰り出し・引き上げ操作等して法面に沿って所望位置まで移動して各種作業を行う場合があるが、何れにしてもこのような法面での作業は足場が不安定なため危険を伴うものであると共に、作業に用いる資材や機材等を一時的に預け置くような場所も確保しづらくて作業効率が悪く、作業者に大きな負担を強いるものであった。   Conventionally, when civil engineering workers etc. work on the slope formed when cultivating mountains etc. and constructing residential land or constructing highways etc., for example, with a wire rope etc. of an appropriate length from above the slope The worker is suspended and supported, and the operator moves along the wire rope in that state, or moves the wire rope with a winch or the like to move it to a desired position along the slope to perform various operations. In any case, such work on the slope is dangerous because the scaffolding is unstable, and there are places where materials and equipment used for the work are temporarily deposited. It was difficult to secure, so the work efficiency was poor, and it imposed a heavy burden on the workers.

一方、このような作業者の負担を軽減するために、例えば、特許文献1(特開平9−72087号公報)には、法面に沿って枠体や足場板等を組み上げて構築する法面作業用の仮設足場が開示されている。このような仮設足場からの作業であれば、作業者は安定した足場を確保できて比較的安全に作業できると共に、休憩場所等としても使用できる上、資材や機材等も一時的に預け置くことができて作業効率面でも優れ、作業者の負担を軽減することができると考えられる。   On the other hand, in order to reduce such a burden on the operator, for example, in Patent Document 1 (Japanese Patent Laid-Open No. 9-72087), a slope constructed by assembling a frame, a scaffolding plate, and the like along the slope. A temporary scaffold for work is disclosed. If working from such a temporary scaffold, the worker can secure a stable scaffold, work relatively safely, can also be used as a resting place, and temporarily store materials and equipment. Therefore, it is considered that the work efficiency is excellent and the burden on the worker can be reduced.
