Description

The present invention relates to a penetration seal for a chimney or other projection through a chimney, i.e. a root seal, the purpose of which is to form a sufficient seal in the junction of the projection through the chimney and the chimney or other projection, e.g. In most cases, such sealing work is carried out on the construction site with seals made of different materials, which are glued, for example, with asphalt glue to the roofing material of the roof and the chimney or a similar projection. A variety of ready-made through-collars made for this purpose are also available. Usually they have to be made separately for different roof pitches, and often they are also quite expensive building components compared to the rest of the roofing.

The object of the invention is to reduce the above-mentioned disadvantages, which is achieved by a chimney or other gutter projection root seal according to the invention, the features of which are set out in claims 1 to 3.

The invention will be explained in more detail below with reference to the accompanying drawing, in which Fig. 1 shows a root seal blank according to the invention, i.e. a seal before installation for a circular cross-sectional mounted as a cavity root seal, Fig. 3 shows a seal according to the invention for a rectangular cross-sectional shape of a chimney or similar projection, Fig. 3b shows the same cross-section, but the opening is shaped to follow the edges or the like, Fig. 5 shows the seal when moved downwards along the surface of the round chimney, and '2' 65469 t Fig. 6 shows the seal in place as a seal for the root of a sloping rain roof and chimney or other protrusion.

The seal 1 for the outer diameter of the round chimney according to Fig. 1, i.e. at this stage still the blank, as will be systematically mentioned below, is made of e.g. 1.5 mm thick butyl rubber with an elongation at break of over 300% over a wide temperature range, as is good for butyl rubber . The blank 1 has a circular opening 2 with a diameter of only about half the outer diameter of the chimney. When the blank 1 is pulled by stretching around the chimney 3 as shown in Figs. 4 and 5, the hole area 2 of the blank 1 is formed so as to form a tight cylindrical collar 4 compressing the chimney 3. In this case, the height of the collar is about 20% of the chimney outer diameter. For large diameters, the hole 2 in the blank 1 may be relatively larger so that the collar does not become unnecessarily high, and for small diameters, such as in the roots of toilet ventilation pipes, the hole 2 in the blank 1 may be less than 1/3 of the outer diameter of the pipe under different elongation conditions. more than 300%.

According to Figures 1b and 3b, the circular or other shaped opening 2 (7) in the blank plate 1 (6) can be vulcanized at its inner edges or otherwise made conical or otherwise compliantly rising (2b and 7b), whereby e.g. the height of the collar is made relatively higher by constant elongation, which is particularly suitable for 'small cantilever diameters'.

With a sloping water roof, the seal can be pulled to an oblique position according to the roof, as shown in Figure 6.

The plate part 1 of the seal in Fig. 6 is sealed to the felt ceiling simply by gluing with some asphalt adhesive. The collar 4 formed during installation generally does not need to be glued to the casing of a round pipe or chimney, as it provides a good seal with its own compressive force. The collar of the glue mat allows the building to descend if necessary (log houses). When using a brick roof or profiled roofing materials, the flexible sealing plate 1 in Fig. 6 can be glued according to the profile of the roofing material. In a brick roof, the upper edge 5 of the sealing plate 1 is placed under the bricks in the usual way. It is also possible to vulcanize the blank 1 according to the profile of the roofing material, whereby it is easy to glue or otherwise neatly attach it to the roofing material.

Claims (4)

A bushing seal for a chimney or other projection through a chimney, consisting of a flexible plate-like part (1) following the water roof and differently watertightly attached to it, depending on the roofing material, and a cylinder a collar part (4), the overall structure of the seal of which is formed by a blank (1) made of rubber, synthetic rubber or other similar stretchable material, the blank having a circular or other shaped chimney or a hole (2, 7) substantially smaller than the outer cross-sectional area of the chimney or when applied from above, is forced to stretch larger around the chimney or the like, forming a cylindrical or other collar-shaped collar portion (4) which is pressed tightly into the chimney or the like when pressed downwards due to stretching , the height of which depends on the size of the above-mentioned hole in the blank and the cross-sectional outer dimension of the chimney or the like to be surrounded and sealed, characterized in that the circular or other shaped opening (2, 7) in the blank (1, 6) is vulcanized or otherwise made conical at the inner edges or otherwise rising to follow the elongation (2b, 7b). * Feed-through seal according to Claim 1, characterized in that a strip-like blank is wrapped around the collar (4) formed by the blank and the projection (3), which is glued into a cross-shaped cylinder of the projection (3) to increase the height of the collar (4). Feed-through seal according to Claim 1, characterized in that a tight sleeve of suitable length is threaded upwards around the collar (4) and the projection (3) formed from the blank plate, ivani ui. height. 1.
