In particular, in the invention according to claim 10, since the above-mentioned band is provided with a protector so as not to contact the edge of the above-mentioned beam, the traveling wind pressure is reduced by the impact given to the curing device. , It becomes difficult to fray at the edge of the beam, and the curing device can be prevented from coming off the beam. Therefore, it is possible to prevent the detached curing device from hindering the operation of the adjacent car or hindering the repair work.

According to the eleventh aspect of the present invention, since the upper and lower ends of the partition are fixed between the horizontal beams, the band can be easily wound. Therefore,
Improvement of efficiency of renovation work can be expected.

In particular, in the inventions according to the twelfth and thirteenth aspects, the partition body is arranged in a desired area according to the contents of the rehabilitation work, and the curing suitable for the predetermined rehabilitation work can be performed. Therefore, improvement of the efficiency of the repair work can be expected.

In particular, in the invention according to Claims 14 to 17, ie, the method of installing a partition device for an elevator hoistway, a mesh sheet is fixed to a beam in the hoistway, and both sides of the mesh sheet are sandwiched by wires. Since the mesh sheet is suppressed, it is possible to restrict the mesh sheet from protruding into each of the predetermined passage and the adjacent passage, and therefore, during repair work of the predetermined car, damage to the partition device due to the traveling wind pressure is less likely to occur, and The operation of the car adjacent to the car is not hindered, and the vibration and noise of the car adjacent to the car make it difficult to make the ride uncomfortable. In addition, the influence of the running wind pressure hardly occurs on the passage side of the predetermined car, and the worker can perform safe and smooth work. Therefore, improvement in efficiency of the repair work can be expected.

In the invention according to claim 15, the wire is pulled by the pulling means, tension is applied to the wire, and the wire in the tensioned state is fixed to the mesh sheet via the fastener. The overhang of this mesh sheet can be regulated more reliably. Therefore, at the time of repair work of a predetermined car, it is possible to more reliably prevent the partitioning device from being damaged by the traveling wind pressure, and to hinder the operation of the car adjacent to the predetermined car, or to prevent the adjacent car from being operated. Poor riding comfort due to vibrations and noise can be more reliably prevented. In addition, the influence of the traveling wind pressure on the curing device can be more reliably suppressed even on the predetermined car passage side, so that the worker can perform safer and smoother work. Therefore, improvement of the efficiency of the renovation work can be expected.

In particular, in the invention according to claim 16, since the wire may be wound around the upper predetermined horizontal beam, the wire can be easily arranged in the hoistway. Therefore, improvement in the efficiency of renovation work can be expected.
