Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold wall joint attachment for connecting a scaffold wall joint material assembled to the outside of a building when constructing a building such as an exterior wall panel type house.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, when building a building 20 such as a house, scaffolds 21 are installed around the building 20,
Convenient for various work. For the scaffolding 21, for example, a wall connecting material that is joined to the outer wall portion of the building 20 is generally used for stability. In particular, when a curing sheet or the like is stretched on the scaffold 21, it is necessary to provide the wall connecting material in order to withstand wind pressure. In the case where the building 20 is made of steel frame, the wall connecting material is obtained by welding, for example, a long nut or a cut bolt to a steel beam and connecting one end to this.

[0003]

However, in the case of an outer wall panel type house, generally, of the joints formed between the outer wall panels, the body gap cover 2 is provided so that the horizontal joint portion is not exposed to the outer surface.
2 etc. Therefore, the vertical joints can only be used to connect the wall tie material to the building 20.

When the vertical joint is used as a connection gap of the wall connecting material, the web portion 2 of the pillar connector 25 is within the joint width of the vertical joint 24 of the outer wall panels 23, 23 as shown in FIG.
A structure in which a hole is made in 5a, a nut 26 is welded to the back surface, and a wall connecting material is screwed can be considered. However, with such a column connector 25 made of C-shaped steel, it is difficult to weld the nut 26 to the back surface of the web portion 25a, and it is not realistic from a technical and cost point of view. Therefore, in such a building, instead of a wall tie material, a construction is used in which a retainer 27 supports the scaffold 21 and a bracket 28 connects the scaffold 21 to the outer wall of the building 20 as shown in FIG. However, the reserve 27 cannot be installed in a small area, and when the bracket 28 is provided, it takes time to process the outer wall surface after the removal work. Therefore, the scaffold 21 is often used in an unstable state without providing any supporting means.

It is an object of the present invention to provide a scaffold wall tie fitting that can be used in buildings using exterior wall panels and that is simple and quick to install and remove.

Means for Solving the Problems The scaffold wall joint mounting hardware of the present invention comprises a screw shaft-shaped main body, a pipe-shaped washer, and a nut member. The screw shaft-shaped main body has a hook portion at the proximal end and a wall tie connecting portion at the distal end. The hook portion is inserted into a hole of a steel column such as a column connector of a building and engages with the inner surface of the steel column. The pipe washer is
One end is engaged with the outer surface of the steel column by loosely fitting the outer periphery of the screw shaft-shaped main body. The nut member is screwed to the screw shaft-shaped main body to fasten the pipe-shaped washer to the steel frame column.

[0007]

In this wall joint mounting hardware, the hook portion of the screw shaft-shaped main body is inserted into the hole of the steel frame column through the vertical joint between the adjacent outer wall panels and engaged with the inner surface of the steel frame column. After this,
By tightening the pipe-shaped washer with the nut member, the wall-connecting fitting can be attached so that the wall-connecting material connecting portion projects outward from the vertical joint between the outer wall panels.
The wall connecting material of the scaffold is connected to this protruding wall connecting material connecting portion.
