Description

[Detailed Description of the Invention] The present invention relates to a handrail clamp for single scaffolding and supporting scaffolding in steel pipe scaffolding for construction use.

Steel pipe scaffolds for construction use include main scaffolds, single scaffolds, and support scaffolds, and these scaffolds are required to be equipped with handrails to ensure safe work.

When a handrail is attached with a conventional pipe clamp, it can be attached to a single scaffold, and in the case of a hugging scaffold, as shown in Figure 1 (side view of handrail 3 attached to a hugging scaffold using a conventional pipe clamp), Since the horizontal cloth 2, which serves as a foothold, and the handrail 3 are vertically aligned, it was impossible for anyone to even stand on the horizontal cloth 2. For this reason, it was necessary to do without attaching the handrail 3 even when working at heights, even though the danger was much greater than with this scaffold.

The purpose of this invention is to provide a handrail clamp that allows work to be carried out safely without causing any obstruction even when a handrail 3 is attached to a single scaffold or a supporting scaffold.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 2 is a front view showing an embodiment of this invention. The backs of both pipe clamps 5, 5 are fixed to both ends of the arm 4. Both pipe clamps 5, 5 are fixed at right angles to each other. The arm 4 may be long enough to allow a person to stand on the horizontal cloth 2. As shown in Figure 3 (a side view of the handrail 3 attached to the scaffold using the handrail clamp of this invention),
When the pipe clamp 5 at one end is tightened to the building site 1 and the handrail 3 is attached to the pipe clamp 5 at the other end, the handrail 3 will be located outside the side cloth 2 by the length of the arm 4, so the handrail 3 will become an obstacle. You can work safely.
