[Problem that the idea aims to solve]

Temporary structures using steel pipes come in various types and structures, so it is difficult to install them. Steel pipes must be placed upright or horizontally depending on the structure of the temporary structure. In the above conventional fixed type guard clamp, depending on the orientation of the steel pipe 5 to be attached, 6. It is necessary to prepare two types of equipment as shown in Figure 7 and use them properly. However, it has drawbacks such as being troublesome to use and manage and high cost. In addition, the conventional dual-purpose type For guard clamps, the fixed position of the steel pipe clamp 15 depends on the direction of the steel pipe 14 to be installed. Not only is the work tedious, but the fixation is incomplete. There are problems such as the possibility of loosening.

[0006] This invention solves the drawbacks of the conventional guard clamps mentioned above and improves the installation direction of steel pipes. It can be used by switching freely and easily, and it can be installed securely. In fact, we have proposed a guard clamp that is strong, has a simple structure, and can be manufactured at low cost. This is what we are trying to provide.
