Definitions

• Sealing device for arrangement over a fastening element of a roof or outer wall cladding
• the invention relates to a sealing device for arrangement over a fastening element of a roof or outer wall cladding, with a hood for covering the fastening element, which surface is formed on its underside for moisture-proof connection with the roof or outer wall cladding.
• FIG. 1 is a schematic illustration, partly in section, of a first embodiment
• FIG. 2 is a perspective illustration of a slightly modified embodiment
• Fig. 5 shows a variant of a detail of the device in section.
• FIG. 1 and 2 is a part schematically a roof cladding element 10 shown in sheet iron, which is connected by means of a fastening element, a screw 11, with another roof cladding element or a carrier (not shown).
• the necessary opening 12 in the roof cladding element 10 is slit-shaped, as can be seen in particular from FIG. 2. This is because the roof trim element 10 is affected by thermal expansion. the screw 11 moves. The direction of the slot runs in the longitudinal direction of the cladding element, while elongations in the transverse directions are absorbed by appropriate profiling of the element.
• the opening 12 represents a hole in the otherwise continuous roof cladding and must be sealed water-tight, as mentioned at the beginning.
• a hood 1 according to FIG. 1 can be used for this purpose, which has a foot part 2 and a head part 4.
• the foot part 2 is made of pickled aluminum and has an annular flange 3 on the underside, by means of which the liquid-tight connection between using silicone rubber 13 as a cement.
• Hood 1 and sheet metal cladding 10 is produced, as will be explained later.
• the head part 4 consists of a conical body 5 and a cover 6, which fits on an opening 7 on the top of the body 5.
• Body 5 and cover 6 are preferably molded parts molded from polyethylene. Black polyethylene (with soot additive) is used with advantage, which increases heat resistance and strength.
• the cover 6 has a rubber seal 8 and a hook 9 or a corresponding eyelet for receiving one end of a resilient tendon 20 in the form of a spiral spring.
• the hook 9 or the eyelet are made of such formed that the upper end of the coil spring can be easily hooked into and detached therefrom.
• the coil spring 20 is attached at its other end to the screw 11. This can be accomplished on the one hand by means of a bracket 14 which can be pushed under the screw head, which avoids changing the screw 11, in particular when the sealing device is subsequently attached, but can also be achieved by means of an eye screw, as shown in FIGS. 2 and 3. Also not shown in the figures is an embodiment in which the spring 20 is attached to a tab bent up from the sheet metal cladding 10 next to the screw 11. The assembly of the illustrated embodiment will now be described in more detail with reference to FIGS. 4a-c. First, the foot part is provided at the bottom of the ring flange with liquid silicone rubber and placed concentrically to the screw 11 on the panel 10.
• the spring 20 is then hung on the screw head and gripped with a spring hook 21 through the conical body 5 of the head part (FIG. 4a).
• the body 5 is now placed on the foot part 2.
• the spring 20 is blocked with a fork 22 and the spring hook 21 is exchanged for the cover 7 (FIG. 4b).
• the lid is placed on the body 5 and held there by the spring force of the coil spring 20 (Fig. 4c).
• the assembly is now complete.
• the foot part 2 is still pulled against the cladding 10 by the spring force - the spring force being selected such that there is a suitable contact pressure for the setting of the silicone rubber 13 results. After the silicone rubber has hardened, the foot part 2 is firmly and liquid-tightly connected to the covering 10, but remains exposed to the contact pressure of the spring.
• the spring 20 has a length that ensures sufficient spring travel for lifting the head part 4.
• the spring 20 performs several functions simultaneously in the invention described here. On the one hand, it serves to press the hood 1 against the lining 10 during the curing of the silicone rubber. Furthermore, it fixes the hood 1 on the fastening element and thus prevents it from unintentionally detaching from the panel 10, but without preventing the hood 1 from running along with the thermal expansion of the panel that occurs. It also serves as a simple holder for the head part 4 on the foot part 2. Finally, it prevents the screw 11 from being unscrewed, as has been observed to date as a result of frequent shocks.
• the sealing device has only been mentioned in connection with roof cladding. However, it should be noted that it is also particularly suitable for exterior wall claddings that do not run horizontally. To this end, those explained above. Effects of the coil spring 20 in an advantageous manner.
• a sealing ring is preferably arranged on the support part of the head part 5 on the foot part 2 in order to prevent the lateral penetration of water.
• FIG. 3 shows a further exemplary embodiment of the invention, the hood 1 resting directly on the panel 10 without a foot part.
• a sealing ring 23 is arranged on the underside of the hood 1 in order to form a liquid-tight seal.
• Spring 20 and cover 6 are of the same design as in the first embodiment. In this embodiment, the entire hood 1 is lifted for checking. It is particularly suitable for applications that do not have to withstand any adverse environmental influences and as a temporary protection.
• FIG. 5 shows an embodiment variant of the contact area between the conical body 5 and the cover 6.
• a rubber seal 8 a spherical cap-shaped, sealing design of the area mentioned is provided. This has the advantage that the problem of the aging of the rubber seal 8 is avoided.
• the invention has further advantages. The fact that the screw 11 remains free of sealing material causes the interior of the hood to face the bottom side of the panel 10 is connected, which prevents condensation from forming inside the hood and attacking the screw 11.
