DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold used for installation of sashes, such as gable installation or eaves ceiling installation, of a portion projecting from an outer wall of a building.

[0002]

2. Description of the Related Art Hitherto, scaffolds used for construction of a portion that protrudes from an outer wall of a building, such as gable mounting or eaves ceiling, and mounting of a sash have been installed so as to surround the entire circumference of the building.

[0003]

In order to obtain the above-mentioned conventional scaffold, it is necessary to assemble it to a predetermined height using a number of columns and a number of cross members, and a large number of columns and cross members are required. There was a problem that the installation took time. In addition, if the roof of the building is overhanging from the outer wall, the scaffold will be installed so as to surround the roof.In this case, the distance between the scaffold and the outer wall will increase, and it will be necessary to attach a sash to the outer wall. There was also a problem that it became difficult to do.

[0004] It is an object of the present invention to provide a moving scaffold that requires only a small amount of columns and cross members, does not require much time for installation, and can easily work even when the roof of the building is overhanging from the outer wall. It is in.

It is another object of the present invention to provide a moving scaffold in which a scaffold main body is stably supported even if the ground has irregularities.

Another object of the present invention is to provide a movable scaffold capable of performing all the work around the building even if the number of rail device components is small.

[0007]

SUMMARY OF THE INVENTION A moving scaffold according to the present invention comprises a scaffold body provided with casters at the lower end of a column, and a caster body provided on the ground along one side of a building. And an outrigger passed between the ground and the scaffold body to stabilize the scaffold body.

[0008] The scaffold main body is composed of four pillars and cross members and diagonal members for connecting and reinforcing them.
Then, in order to install the moving scaffold, first, the rail device is installed on the ground, the scaffold main body is assembled on the rail device, and finally the outrigger is extended to fix the scaffold main body. The rail device can be installed along the outer wall of the building even when the roof of the building is overhanging from the outer wall, and the rail device does not need to be installed on all sides of the building, and the work on one side of the building can be done. When finished, remove it and place it along the next side of the building. Therefore, only a small amount of struts and cross members are required, and the installation does not take much time.Also, even if the roof of the building is overhanging from the outer wall, the spacing between the scaffold body and the outer wall of the building should be a space suitable for work. And work is easy.

The rail device comprises one base member and a plurality of extension members. The base member includes a pair of left and right rails and four jacks for supporting front and rear ends of the left and right rails. It is preferable that the component members include a pair of left and right rails and two jacks that support one of the front and rear ends of the left and right rails. This way, all rails will be at the same level,
By adjusting the height of each jack, the scaffold body is stably supported by the rail device even if the ground has irregularities.

[0010] It is preferable that a coupling engaging portion to be engaged with an adjacent base component or extension component is provided at an end of the extension component not provided with the jack. With this configuration, after the base component is installed, the extension component is connected to the extension component via the coupling engagement portion, and another extension component is connected to the extension component via the connection engagement portion. By connecting the members, the rail device can be easily installed. Further, it is possible to easily remove the extension component member of the completed portion and connect it to the portion to be constructed, so that if there is one base component member and two or three extension component members, Can do all of the construction around the building.
