Description

The present invention relates to a duck roof underlay seal for a tubular grommet comprising a helmet portion and a surrounding flange portion, the flange portion being secured to the underlay by a double-sided tape pre-mounted on the underside of the flange portion. The protective film is removed from the double-sided tape before the flange member is placed over the underlay.

A defect in a previously used underlay seal is that it is not tight against the put-10 and against the base plate, but is exposed to high winds to allow the proper insulation to be wetted by snow and water.

Brick ceilings are made of either concrete or clay bricks. The brick ceilings are waterproof in normal rainfall, but if the wind is strong at the same time, the water will sink from the 15 brick gaps below the brick, where it will drip onto the underlay. For this reason, underlayment is used on brick ceilings.

The pipes passing through the underlayment must also be capable of being sealed so that water cannot escape from the sledge to the actual thermal insulation. Often, the pipes 20 are also insulated from below the roof to the underside of the lead-through, i.e. the insulation must also pass through the underlay. This poses a major challenge to the design of the underlay seal.

't δ c \ j ^ The underlay can be 20 - 100 mm off the roof. This is due to the fact that the roof chairs cp 25 can be 600 - 900 - 1200 mm apart. Then the thickness o x of the ribs changes. For example, in a 900 mm roof top division, 50 mm thick ribs (50 x

CL

50mm). Also, the angle of inclination of the roof also poses its own problem with the design of the under-roof seal, the steeper the roof the more necessary it is to stretch the under-roof seal.

DE 44 30 657 A1 discloses an underlay seal of the type mentioned above which is of a film-like material and whose upper part of the helmet part can be clamped against the outer surface of the tube by means of a clamping band.

FI 113291 B discloses an underlay seal comprising a plate-like flange portion and a membrane collar or helmet portion attached thereto. The plate-like flange portion is primarily to be mounted on the support ribs and the underlay can be secured to the upper surface of the flange portion with double-sided tape. The upper end of the helmet part can be attached to the outside of the tube with tape.

30 through which elastic straps at the top of the hood portion of the underlay can be threaded to lock 3 plastic parts in place. There may be 2-6 rubber bands, preferably 4 bands.

Preferably, the flange portion has three corrugations that rotate the helmet portion, allowing the height of the gasket to be adjusted to different heights of ribs and to different ceiling angles.

Thanks to the seal of the invention, the lead-through, which is passed through the underlay through a wide bore, is easy to insulate under the roof to prevent them from freezing during the winter.

In the following, the invention will be described in more detail with reference to the drawing, where: Figure 1 is a perspective view of an example of an underlay gasket according to the invention; Fig. 2 shows an example of a hard plastic annular part to be fitted to the helmet part of the seal .; Figure 3 shows the underlay seal of the invention affixed to the underlay; yeah?

By means of the rubber bands 4, the upper end of the sealing helmet part 2, stiffened by the annular part 5, can be tightened tightly against the inner walls 4 of the penetration helmet part 6 by fastening the rubber bands 4 firmly to the pins 7 at the top.

The gasket flange portion 3 is secured to the underlay 8 with double-sided tape 5 pre-mounted on the underside of the flange portion 3. For further attachment to the underlay 8, the tape 9 can be pulled along the outer edges of the flange member 3.

In the embodiment shown in Fig. 1, the hard plastic ring part 5 is molded onto the rubber helmet part 2.

Fig. 2 shows an embodiment in which the hard plastic ring part 5 is a separate part with holes 10 at its upper edge through which rubber bands 4 at the upper end of the helmet part 2 can be threaded to lock the ring part 5 in place. In the embodiments shown in the drawing, there are 15 6 rubber holes, whereby also at the top of the part 5 there are correspondingly 6 holes.

Preferably, the flange portion 3 has three hinged portions 2 with rotating corrugations 11, which allow the height of the seal 1 to be adjusted to different heights of ribs and to different ceiling angles.
