Gully for multilayer flat roofs

The innovation concerns a gully for multilayer flat roofs, consisting of an insert that suffers from the inlet opening, a Gully pot with drain and a connecting piece arranged in between, the lower edge of which extends into the gully pot and is attached with a clamping and locking ring.

The new rank is based on the task of converting the pre-assembled in usually angled gully pot and the also preassembled insert forming the inlet opening during final assembly on the To connect construction site with a handle. It is known to preassemble the insert forming the inlet opening in such a way that the connection piece made of rubber or plastic already extends into the angled gully pot during assembly at the construction site. So far, however, it was only possible with greater installation effort to securely in the angled this connector To attach the gully pot.

The metal rings used for this purpose, those with rubber are sheathed, are difficult to insert at the construction site; also the absolutely perfect fit is the one Backflow security guaranteed, hardly verifiable.

According to the innovation, these negative parts are avoided in that the clamping and locking ring is designed as an expanding ring.

The clamping and locking ring can be single or multi-layer Be designed coil spring, the ends of which can be appropriately bent inwardly as handles.

According to another embodiment, the clamping and securing ring has a clip lock.

To improve the connection, it is also proposed that the wall of the gully pot have a groove. The gully pot however, it can also be provided with an additional ring known per se, which protrudes into the free inlet of the gully pot. Furthermore, the connecting piece can have a thickening at the lower edge.

The connection piece of the insert can be safely and easily inserted into the angled gully with a simple handle fasten verifiably; Due to the special design of the GuIIy inner contour, subsequent pulling out of the Connection piece excluded after assembly.

The innovation is explained in more detail on the basis of the drawings. It shows:

1 shows a section through a built-in flat roof Gully;

FIG. 2 shows a partial view of FIG. 1 with a gully wall having a groove; FIG.

3 shows a partial view of FIG. 1 with the additional ring protruding into the inlet;

4 shows a clamping and securing ring with a clip lock;

Fig. 5 shows a clamping and locking ring in the form of a Coil spring.

In the embodiment according to FIG. 1, this is the inlet opening forming insert 1 connected to the angled gully pot 2 by the connector 3, which by means of a Clamping and locking ring 4 is attached in the angled gully 2.

Through a groove 5 ~ n in the wall of the gully pot in the fastening area or by using an existing or additionally attached ring 6 in the angled gully given a security against pulling out the connector 3 after assembly.

This security can still be achieved by a thickening 7 at the bottom Edge of the connector 3 can be increased.

The clamping and securing ring 4 can be made of metal or plastic and is in the embodiment

j | [7517325 iaoft75

according to FIG. 4 by means of clip lock 8 during installation. The parts of the clip fastener are with each other and with the Ring articulated.

The embodiment shown in Fig. 5 shows an in Metal or plastic executed clamping and securing ring 4 which is designed as a spiral spring, the ends 9 of the spiral spring as handles for contracting the clamping ring can be used during installation.
