It relates to improvement of the device.

[0002]

2. Description of the Related Art Conventionally, when a building such as a hotel is newly built or an existing building is renovated, a work floor is built around the building. As the working floor, a steel pipe scaffold (single pipe or frame scaffold) is built around the building so as to surround the building, and a gondola is hung from the roof of the building for use.

[0003]

Work floors made of steel pipe scaffolds usually have a height that extends from the ground to the roof or roof of the building around the building, and is generally very large. As a result, the ratio of the cost of temporary installation of the scaffold to the construction cost becomes large.

When a work floor is constructed with steel pipe scaffolds when renovating a hotel or the like, the steel pipes or the like impede viewing the outside from a guest room or the like, in particular, view of the landscape. It may be necessary to suspend business during the construction period. For this reason, it is not easy to complete the repair work, and there is a possibility that the pain of the part requiring the repair may progress.

On the other hand, when a gondola is suspended from the roof of a building and used as a work floor, there is a disadvantage that a suspension device must be installed on the roof, and the gondola is moved right and left. For this purpose, it is necessary to appropriately arrange the roof suspension system in the direction in which it is to be moved.
For this reason, there is a drawback in that it is not suitable for construction contents that require frequent movement to the left and right as the work proceeds.

In order to avoid such drawbacks, there has been proposed a method of constructing a work floor for one floor at a time by connecting a plurality of the gondolaes on the left and right, but this requires a temporary construction cost. In addition, when this method is applied to a hotel or the like, the use of a guest room for at least one floor may be inappropriate due to the gondola.

The present invention can be used at a very low cost as compared with the above-mentioned steel pipe scaffold or hanging gondola, and can be locally installed at a place where the work is required, and at least a part other than the local temporary place is used. In this regard, an object of the present invention is to provide a temporary work floor apparatus that can prevent the user from observing the outside from the inside of a building and can easily install, move, and dismantle and remove the work floor.
