BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe cover joint.

[0002]

2. Description of the Related Art Refrigerant piping for an air conditioner installed on the wall surface of a building is covered with a piping cover on the outside of the piping in order to keep the appearance of the building beautiful and to protect the piping from wind, rain and impact. Sometimes. As such a pipe cover, a straight pipe-shaped one in which a set of half halves made of a half-divided tubular body is united to be separable is used.

Further, in the peripheral wall (wall) of the rooftop, as shown in FIG. 3, the pipe P may be disposed over the top T1 of the wall W. In this case, a pair of elbow-type (bent at right angles) joints E1, E near the top T1.
2 are connected by a connecting member J having a straight tubular shape so as to have a shape in a side view, and the straight tubular piping covers C on the front and back surfaces of the wall W are connected. Further, as shown in FIG. 4, two pipe covers C, C
There is a case where the above-mentioned bellows pipe B is connected to the known bellows pipe B by a connecting member J, and the bellows pipe B is bent so as to get over the top portion T1 of the wall surface W.

By the way, as can be understood from the drawings, for example, in a peripheral wall (wall) provided on a rooftop or the like, the thickness of the top portion T1 may be made larger than that of the lower portion so as to have a T-shaped cross section for reinforcement. is there. When the top of the wall surface is formed so as to project to the front and rear in this way, when the straight tubular piping cover is connected by the former method, the joint portion between the piping cover C and the elbow joints E1 and E2 opens with time. As a result, the intended purpose of pipe protection and appearance improvement may not be achieved. This is because when the top portion T1 of the wall W projects outward in the front-rear direction as described above, a step portion T2 is formed below the top portion T1. Therefore, the pipe cover C is separated from the wall surface near the step portion T2 and This is because they must be slanted and fixed at the lower part of the wall surface, and as a result, an opening force acts on the lower ends of the elbow joints E1 and E2.

On the other hand, in the latter method, since the bellows portion is flexibly deformed in accordance with the bending angle of the wall surface, no gap is generated between the pipe cover C and the bellows pipe B. However, the bellows portion of the bellows tube B, which is arranged and bent at the top portion T1 and the step portion T2 of the wall W, is easily deteriorated with time due to the bending stress, and is likely to cause a crack.
