ることで安全を図っていた。Conventionally, such a suspended scaffold is a scaffold composed of a plywood panel, a plywood scaffold board, a cedar board, or the like, on which a large pulling material is supported by a hanging material hanging down from a structure, and on a joist laid between the large pulling materials. The boards were placed to form a working floor. These scaffolds must be fixed at two or more points in order to prevent dislocation or falling off. In addition, care must be taken to prevent the end of the scaffold plate from protruding. For this reason, in the conventional work floor, the end of the scaffold plate is overlapped on the joist, and safety is achieved by locking these and the joist.

Also, a scaffold is laid on the joist with a predetermined projection size, and further a continuous scaffold is laid on the joist while observing a predetermined overlapping size, and these ends are fixed to the joist with a band material or the like. The work was complicated, and was dangerous when performed at a high place.

Although the external appearance of the beam body is substantially rectangular, a pair of reinforcing ribs is provided in the opening, and a connecting plate is fixed between these opposing reinforcing ribs, while the center of the tip of the bent joist plate is bent upward. In this configuration, the joist folded plate is hooked with the connecting plate interposed therebetween, so that the movement in the axial direction of the large pulling material is suppressed. If a notch for accommodating the cross member is provided at the end of the bent plate of the ladder-shaped frame, and the cut-out interval and the cross-member interval are matched, the installation of the ladder-shaped frame becomes easy.

Since the mounting locations are determined at predetermined intervals, the installation becomes easier. In addition, a long hole 6e is formed on the side surface of the beam main body where the connecting plate 15 is provided, so that it becomes a mark. In addition, the joist 8 which does not need to take the blow-up prevention measure is the connecting board 1
It is not limited to the position of 5 and can be installed at any position of the large drawing material 6.
