DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for suspending an outer wall material. More specifically, the present invention relates to an improvement relating to operability and safety of a suspension device for an outer wall material used when attaching an outer wall material such as a curtain wall to an outer wall of a building.

[0002]

2. Description of the Related Art Conventionally, as a device for suspending an outer wall material, the outer wall material is directly suspended by a crane, or a hanging wire is hung over the top and bottom of the surface of the outer wall material (opposite to the mounting surface) and the mounting surface. The method of suspending this with a crane has become widespread.

[0003] Instead of this, there is a type in which an end face of an outer wall material is sandwiched in a frame suspended by a crane or the like, and a scissor-shaped holding portion is provided.

[0004] This conventional outer wall material suspending device is constructed around the outer periphery of a building by holding the outer wall material accumulated on the ground or the like in a holding portion and transporting the outer wall material to a position near the outer wall of the building by moving a crane or the like. An operator who waits on the scaffold pulls the outer wall material, performs an installation work (sometimes a temporary fixing work) on the outer wall of the building, and then removes the hanging wire and the holding portion.

[0005]

As described above, the outer wall material is often hung directly by a crane as described above, but since the head of the outer wall material is hung directly, the outer wall material is sequentially attached from the upper part to the lower part of the building outdoor wall. In such a case, the hanging environment, such as the outer wall material whose head is suspended abutting the upper outer wall material already mounted, hinders the mounting, and the mounting is impossible. Therefore, it can be used even when it is attached from the lower part to the upper part of the building outdoor wall, and is limited to a narrow range.

Further, when removing the hanging wire and the holding portion from the outer wall material by manually lifting the hanging wire and the holding portion by, for example, a worker leaning out of a scaffold, the worker must remove the hanging wire and the holding portion from the outer wall material. Not only was it troublesome to remove, but also involved the risk of falling.

Further, the outer wall material is required to be parallel to the building outdoor wall, but the posture of the outer wall material may be inclined depending on how the wires are wound around or attached to the holding portion. In addition, although the posture may be tilted due to the wind, etc., it is not only difficult for the worker to pull in the inclined outer wall material, but it is a very dangerous work. For this reason, the problem of low operability and safety has not been solved in use in the installation work of the outer wall material.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described problems, and has as its object to provide a highly operable and safe external wall material suspension device for use in mounting an external wall material. I do.

[0009]
