In this rain breaker, a fixed part 4 a fixed to the iron plate wall 3 and a movable part 4 b fixed to the pipe 6
Means that the movable part 4b is relatively movable within the range of the distance between the first end plate and the second end plate, so that the movement of the pipe 6 due to thermal deformation is not hindered. Installation errors can be absorbed.

[0008]

However, in such a rain breaker, since the movable portion 4b of the rain cover 4 moves following the movement of the pipe 6 due to thermal deformation, the movable portion 4b moves to the outside of the building outdoor wall 1. Overhang is required, and a certain space is required outside the outdoor building wall 1. If there is another structure near the outdoor building wall 1, the movable portion 4 of the rain cover 4
There is a problem that b interferes with other structures.

[0009] An object of the present invention is to provide a rain fighting device capable of avoiding interference with a structure or the like near the building outdoor wall, in which the outside of the building outdoor wall is small, in order to solve the above problem. Is to do.

[0010]

According to the present invention, there is provided a rain breaker for piping which penetrates a building outdoor wall, wherein the rain cover is provided so as to protrude outside the building outdoor wall. A movable ring slidable in the axial direction of the pipe is attached to the outer periphery of the outer plate of the pipe.

[0011]

FIG. 1 is a side sectional view showing an outline of a rain breaker according to the present invention. As shown in the drawing, a rain breaker according to an embodiment of the present invention is mounted on an outdoor side of a steel plate wall 3 attached to an opening of an outer wall provided on an outdoor wall 1 of a building via a metal fitting 2. Rain cover 40
And a movable ring 50.

The iron plate wall 3 is provided with a circular iron plate wall opening through which a pipe 6 whose outer surface is covered with a heat insulating material 7 and whose outer surface is covered with an outer plate 8 penetrates. The inner diameter of the iron plate wall opening is set to be slightly larger than the outer diameter of the outer plate 8 of the pipe 6 so that the movement of the pipe 6 penetrating the iron plate wall opening due to thermal deformation is not hindered and installation errors are taken into account.

The rain cover 40 has a cylindrical structure whose inner diameter is larger than the inner diameter of the iron plate wall opening. One end is fixed to the iron plate wall 3 and the other end is covered with a heat insulating material 7 and an outer plate 8 at the center. An end plate provided with a circular opening through which the cut pipe 6 penetrates is attached. The inside diameter of the opening is made slightly larger than the outside diameter of the exterior plate 8 so that the movement of the pipe 6 penetrating through the iron plate wall opening due to thermal deformation is not hindered and the installation error is taken into consideration.

An annular movable ring 50 is provided on the outer periphery of the exterior plate 8 of the pipe 6 between the iron plate wall 3 and the end plate of the rain cover 40.
Is slidably mounted in the pipe axis direction. Movable ring 50
Is larger than the inner diameter of the iron plate wall opening and smaller than the inner diameter of the rain cover 40, and the inner diameter of the movable ring 50 is slightly larger than the outer diameter of the outer plate 8, and is set in the pipe axial direction. To be slidable.

By attaching such a movable ring 50 to the outer periphery of the outer plate 8 of the pipe 6 between the iron plate wall 3 and the end plate of the rain cover 40, the outer plate 8 and the rain cover 40 are attached.
It is possible to prevent rainwater from entering the building from the gap with the opening. Since the movable ring 50 can slide in the pipe axis direction without following the movement of the pipe 6 due to thermal deformation, the distance between the iron plate wall 3 and the end plate of the rain cover 40 can be reduced, and The overhang to the outside of the building outdoor wall can be reduced, and interference with structures and the like near the building outdoor wall can be avoided. In addition, the sealing property can be improved by wrapping the cushioning material in the gap between the exterior plate 8 and the movable ring 50 to such an extent that the sliding between them is not hindered. Intrusion into the room can be prevented better. In addition, a drain hole 9 for discharging water or the like inside is provided below the rain cover 40.

In the above embodiment, the shape of the iron plate wall opening is circular, but it may be a shape other than circular, for example, square.

Although the rain cover 40 has a cylindrical shape, it may have a shape other than a cylindrical shape, for example, a square cylindrical shape.

Further, although the shape of the movable ring 50 is annular, the outer edge of the movable ring 50 may have a shape other than a circle, for example, a square or other polygons.

[0019]

As described above, in the rain breaker according to the present invention, since the movable ring is attached to the outer plate of the piping in the rain cover, rainwater is built up from the gap between the outer plate and the opening of the rain cover. There is an effect that it can be prevented from invading the indoor. Furthermore, since the movable ring can slide in the axial direction of the pipe without following the movement due to thermal deformation of the pipe, the distance between the iron plate wall and the end plate of the rain cover can be reduced, and the rain cover can be installed on the outdoor wall. There is an effect that it is possible to reduce the protrusion to the outside and to avoid interference with a structure or the like near the building outdoor wall.
