DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold support structure capable of detachably fixing a scaffold to a building, and more particularly to a scaffold support structure suitable for constructing a laterally extending outer wall and a scaffold support fitting thereof.

[0002]

2. Description of the Related Art In order to prevent wobble and overturning, temporary scaffolds are fixedly supported at fixed intervals by pillars and support brackets which are detachably fixed to base materials for walls. An example of this type of support fitting is seen in the support fitting of Japanese Utility Model Publication No. 5-27631. However, a scaffold support structure using such a support fitting is not suitable for constructing an outer wall panel. When constructing an exterior wall panel, use the scaffolding provided in advance for the construction of the building as it is, but remove the part where the exterior wall is stretched out of the support bracket fixed to the aggregate such as the foundation of the exterior wall or columns. After the outer wall panel is stretched on the removed portion, the support bracket is fixed again from above the outer wall stretched over the building to secure the scaffold. For example, the female screw is fixed to the outer surface of the outer wall panel, and the scaffold supporting metal provided for re-securing is screwed into the female screw to secure the scaffold. In particular, in the case of a laterally-extended exterior wall, the exterior panel is often raised upward from the bottom edge of the wall, and construction cannot be carried out while alternately repeating formation of the exterior wall and removal of the scaffold. It becomes essential.

Can easily be re-secured. However, after removing the scaffold, the head of the screw is exposed on the outer surface of the outer wall panel, so it may be badly formatted and cause rust,
There is also a problem with waterproofing, such as rainwater seeping into the wall panel and indoors via the screw portion.

In order to avoid such disadvantages, the connecting portion of one of the outer wall panels connected up and down is fastened and fixed with screws.
A panel mounting structure is adopted in which the screw head is covered by the connection part of the next outer wall panel so that the bolt is not exposed on the surface of the panel. In such a panel mounting structure, it is not possible to attach the scaffold support bracket to the building by penetrating the panel, so use an opening such as a window to secure one end of the scaffold support bracket, and secure the scaffold again. I have. The problem is,
In the case of a windowless building such as a warehouse or a factory, it is not possible to secure a scaffold again. This means that the application target of the outer wall concealing the screw head and the like is limited to a building having an opening such as a window.

Accordingly, an object of the present invention is to provide a scaffold support structure capable of securing a scaffold for wall panel construction without damaging the outer wall panel, and a support for scaffold support in a horizontal exterior wall capable of concealing a screw head and the like.
