description

The invention relates to a sealing flange for sealing the space between a sanitary pipe and a prefabricated component surrounding the sanitary pipe at a distance. j)

In prefabricated houses, the time-saving laying and installation of the sanitary pipes is a special feature Problem. To save time. " Assembly is known, for example, so-called prefabricated sanitary blocks to assemble, which carry different pieces of pipe in a PU foam body. The sanitary block is between the wall panels of prefabricated walls inserted, ί the pipe sections end in front of or in openings in the, i Wall panels of the prefabricated component, where they ■

then be extended through the breakthroughs. On Jj

the side facing away from the sanitary block are then | j Taps, mixers, sanitary objects, etc. connected |

and used by the user. To prevent | user-side leaking water through the | ' cracks can pass through and possibly I the wall panels or the user-attached 1 Cladding, such as tiles or the like, is peeling off or damaged between the openings and a suitable sealant is injected into the passed pipe. The disadvantage here is that this known type of seal due to different expansion properties, etc. of the sanitary pipe and the wall panels are not tight enough. From the user side into the breakthroughs

urgent water therefore leads to damage to the wall panels or the wall cladding.

The object of the invention is therefore to provide a sealing flange for sealing the space between a sanitary pipe and a spaced apart the sanitary pipe specify surrounding prefabricated component that is easy to apply and reliably seals.

According to the invention, this object is achieved by a dense mat made of elastic sheet material, which has an opening in the middle area, the diameter of which is smaller than the outer diameter of the sanitary pipe to be sealed.

The advantages of the invention are in particular that the tight mat with its opening over the Pipe extension piece passed through the wall panels can be pulled and there due the inherent elasticity of the material lies flat and to produce a reliable seal with a suitable adhesive can be glued to the outer circumference of the pipe. The free surrounding edge of the The mat can then - with a suitable adhesive material, be glued flat against the outer surface of the wall panels, whereby a reliable tight cover from the plumbing pipe to the wall panels is achieved. Because of the elastic properties of the mat, this seal is also long-term resistant to Material expansion and tension. In addition, the sealing flange also forms an effective additional Sound insulation, which is particularly important for prefabricated components.

Ι According to a particularly preferred embodiment

According to the invention, a sleeve made of elastic material is provided around the opening of the mat, whose diameter is also slightly smaller than the outer diameter of the one to be sealed Plumbing pipe is. This makes sticking the mat on the sanitary tube much easier; the pressure is increased when gluing.

The sealing flange is particularly preferably supplied with a sanitary pipe extension piece / which is inserted through the opening of the mat and glued flat to the edge of the opening with the mat is. The assembly is then considerably simplified by the fact that only the short plumbing pipe extension piece needs to be screwed on; the gluing of the mat on the plumbing pipe is carried out by the manufacturer.

Advantageous developments of the invention are d: 'rch characterized the features of the subclaims.

In the following two exemplary embodiments of the invention are explained in more detail with reference to the drawing.

Show it:

Fig. 1 is a plan view of a first embodiment of the sealing flange;

2 shows a plan view of a second embodiment of the sealing flange; and

FIG. 3 shows a side view of the sealing flange according to FIG. 2.

1 shows a front view of a sealing flange 1. A dense mat 2 made of elastic web material contains an opening 4, which is delimited by an edge 6, approximately in its central region. The diameter of the opening 4 is smaller than the outer diameter of the sanitary pipe to be sealed, eiaiuit when the mat 2 is pulled up, the edge area 6 lies flat around the sanitary pipe in question and can be glued there under the pressure resulting from the inherent elasticity.

Figs. 2 and 3 show a second embodiment of the Dich! flange in plan or in section. at In this embodiment the dense mat 2 is on a plumbing pipe extension piece 8 pulled up and attached to the edge area 6 by means of a suitable adhesive 10 flat on the outer surface of the extension piece 8, see Fig. 3. The extension piece 8 is on a sanitary pipe, which is through a Breakthrough 12 of a prefabricated component is passed, screwed on. Then the outside area the mat 2 is glued to the outer surface of the prefabricated component 12.
