SUPPORTING TOOL FOR WORKING SCAFFOLD IN VERTICAL SHAFT, SUPPORTING TOOL UNIT, WORKING SCAFFOLD IN VERTICAL SHAFT AND CONSTRUCTION METHOD OF WORKING SCAFFOLD IN VERTICAL SHAFT

摘要

To provide a supporting tool for a working scaffold in a vertical shaft, a supporting tool unit, the working scaffold in the vertical shaft and a construction method of the working scaffold in the vertical shaft, excellent in economic efficiency, workability, flexibility of a scaffold setting position, and safety.SOLUTION: A supporting tool 1 for a working scaffold in a vertical shaft is formed by integrating a horizontally rotatable part 2 bolt-jointed 15 to the vertical shaft with a single pipe part 3 connected to a scaffold construction single pipe 21 via a clamp 22. In some cases, a taper 2b for increasing the degree of freedom of horizontal rotation is formed at both sides or one side of the horizontally rotatable part 2. In some cases, a reinforcement rib 4 is provided at an upper part and/or a lower part of the horizontally rotatable part 2. In some cases, locking means for the clamp 22 is provided to the single pipe part of the supporting tool 1. In some cases, the horizontally rotatable part 2 and/or the single pipe part 3 are drilled with a through-hole for inserting a binding material like an annealing wire.SELECTED DRAWING: Figure 2
