[0002]

2. Description of the Related Art In general, when repairing a wall surface, a scaffold frame is assembled around a building. As the scaffolding frame, there is known one in which a plurality of horizontal pipes are passed between a plurality of vertical pipes, and intersections of the vertical pipes and the horizontal pipes are connected by pipe clamps.

[0003] In the scaffold frame, a wall connecting bracket is attached to the wall surface of the building, and the vertical pipe is supported by the wall connecting bracket.

FIG. 1 shows a conventional wall connection fitting. In this wall connection fitting A, a pipe clamp 2 is rotatably connected to one end of a shaft 1, and a screw shaft 3 is provided at the other end of the shaft 1.

The shaft body 1 has a large-diameter pipe 1a and a small-diameter pipe 1b inserted inside the large-diameter pipe 1a. A threaded rod 4 incorporated in the large-diameter pipe 1a is connected to the end of the small-diameter pipe 1b. The handle 5 is screwed into a screw hole (not shown) provided in the portion, and a handle 5 that penetrates the large-diameter pipe 1a in the radial direction is attached to the end of the screw rod 4. By rotating the rod 4, the large-diameter pipe 1a and the small-diameter pipe 1b move relatively in the axial direction, and the length of the shaft body 1 is adjusted.

[0006] In addition to the above-described configuration, the wall connecting bracket is not provided with the large-diameter pipe 1a shown in FIG. 1 and the screw rod is exposed to the outside, and a pipe clamp is provided at the tip of the screw rod. Some are rotatably connected.

In the formation of a scaffold frame using the above-mentioned wall connecting fitting, an anchor is usually fixed to a building, and a screw shaft of the wall connecting fitting is screwed into a screw hole provided in the anchor.
