2. Description of the Related Art Temporary scaffolds and temporary handrails using single pipes are constructed by tightly connecting the single pipes in a cross shape by means of fastening fittings called clamp fittings. The clamp fitting (30) (see FIG. 9) is composed of two clamp halves (31) and (31) rotatably connected to each other, and each clamp half (31) is a single pipe pipe. A main body (33) having a semi-circular support surface for pressing approximately half of the tight-fitting side of (32) and an anti-fastening side of a single pipe (32) rotatably attached to one end of the main body (33). A rotating member (34) for pressing and a male screw part that is rotatably attached to the other end of the body (33) and can be inserted into a notch (35) formed at the tip of the rotating member (34). (3
6) and a nut (3) screwed to the male screw part (36).
7) and the male screw part (36) is provided with the notch (35)
The nut (37) is rotated in the state of being inserted into the body, and the tip side of the rotating member (34) is pressed toward the main body (33) so that the rotating member (34) tightens the single pipe pipe (32). It is configured.

Since the male screw portion (36) of the clamp fitting (30) is a member which projects outward, there is a risk that the clothes and body of the worker will be caught by it. For this reason,
In recent years, what is called a clamp cover is used to cover the clamp metal fittings to improve the safety of the work site.

As the clamp cover, there has conventionally been proposed an injection-integral molding type made of a hard synthetic resin as shown in FIG. As a scaffolding for a temporary construction site, there is a pipe scaffolding in which a vertically arranged single pipe (32) and a horizontally arranged single pipe (32) are tightly connected to each other in an intersecting manner. The injection-molded clamp cover is mainly used as a cover material for the binding fitting in the pipe scaffold.

The clamp cover (42) has a pipe gripping portion for gripping a part of the intersecting single pipes (32),
It is a hard synthetic resin molded product integrally formed with a half body cover portion that covers the clamp half body (31), and the pipe gripping portion is formed into a C-shaped cross section having an opening width smaller than the pipe diameter. The two pieces that form both edges of the open portion are elastically deformed respectively so that the single pipe (3
The clamp cover (42) can be attached by inserting 2) and inserting and fixing the single pipe (32) in the pipe gripping part.

[0006]

However, the above-mentioned conventional techniques have the following problems. Since the entire clamp cover (42) is integrally molded of hard synthetic resin, the allowable deformation amount of the deformable portion is small. Therefore, the amount of deformation of the piece sandwiching the open portion was small, and a sufficient locking portion could not be formed, and the single pipe (32) could not be sufficiently gripped. The gripping force can be increased by reducing the width of the opening, but it is not practical because it requires a considerably large force to widen the width to allow the single pipe (32) to pass. Also, because it is composed of a single member,
It is difficult to add variety in design, and it is difficult to contribute to improving the appearance of the work site.

The present invention has been made in view of the above circumstances, and is easy to install, and once installed, it does not easily come off, and can be easily removed as needed, and further, it has various designs. The purpose of the present invention is to provide a clamp cover that can improve the appearance of the work site by improving its properties.
