The sealing plate 9 has an opening Ö for the fastener 6 on, over which the fastener 6 from the magnetic body 5 the mounting device 5 . 6 led to the outside.

Between the sealing plate 9 and the fastener 6 is a sealing ring structure 11 arranged, for watertight sealing of the opening Ö and thus in particular between the sealing plate 9 and the fastener 6 or the magnetic body 5 ,

The installation and function of the fastening device 100 can essentially be described as follows:
On the building construction 1 with the integrated metal plate 2 becomes the protection device 4 (eg a thin roofing membrane or a thin plastic protection plate) placed around the underlying construction 1 and in particular to protect the underlying rooms from the moisture present in the outdoor area (eg due to rainwater). The attachment of the protection device 4 on the building construction 1 can be done by simply laying on, by means of an adhesive connection or by means of another mechanical attachment (eg., By a clamping device). Due to the flush arrangement of the metal plate 2 to the outer surface of the building structure 1 is the installation of the protection device 4 on simple and the protection device 4 gentle way without paragraphs or offset edges possible.

The powerful magnetic body 5 becomes on the outside opposite the metal plate 2 on the protection device 4 placed. The magnetic body 5 itself has the integrated fastener 6 (For example, a screw located in a counterbore or a welded-on screw or eyelet), with the help of the magnetic body 5 preferably on the support structure of the utility 8th can be attached.

To the fastener 6 becomes the supporting structure of the utility 8th mounted in such a way that by external influences on the utility 8th arising forces (eg by wind) directly to the magnetic body 5 can be forwarded. From the relative to the metal plate 2 outer magnetic body 5 Due to the magnetic effect, the forces are transmitted directly to the inside, beyond the protective device 4 lying metal plate 2 ,

The metal plate 2 In turn, direct the forces with the help of their own, through the fastener 3 generated anchorage in the building structure 1 one.

By the contact of the magnetic body 5 with the protection device 4 and by the magnetic action on the underlying metal plate 2 Forces can be both perpendicular and horizontal to the surface of the building structure 1 be transmitted. Even moments from tilting or torsional effects can by the magnetic body 5 on the metal plate 2 be transmitted. A penetration of the protection device 4 is not required for this.

The z. B. round, square or polygonal sealing plate 9 is on the top (ie outside) of the magnetic body 5 attached. This attachment can be done by the magnetic force itself, by an adhesive connection or by a mechanical screw, clip or clamp connection. In the area of the penetration of the sealing plate 9 with the fastener 6 of the magnetic body 5 itself becomes the sealing ring structure 11 (For example, a sealing ring made of EPDM) waterproof so that no water and no moisture from outside the area of penetration of the fastener 6 and the magnetic body 5 can penetrate itself.

The sealing ring structure 11 can be omitted in particular when the fastener 6 (eg a threaded screw) directly to the top of the magnet body 5 welded or glued on.

On the underside (inside) of the sealing plate 9 is the preferred round, square or polygonal, annular sealing element 10 mounted, this assembly can be achieved by gluing or mechanical clamping or screwing. Due to the precisely definable distance between the sealing plate 9 and the protection device 4 can now be a precisely determinable contact pressure of the sealing element 10 against the protection device 4 be set up. This will be a watertight finish of the interior 12 in which the magnetic body 5 is reached.

By the watertight completion of the interior 12 becomes a protection of the magnetic body 5 before moisture reaches what the long-term emerging corrosion of the magnetic body 5 (eg with neodymium magnets) can prevent. On the other hand, a penetration of water or moisture through in the region of the magnetic body 5 possibly weakened fender 4 prevented yourself. This weakening of the protection device 4 can z. B. by the permanently high transverse pressure in the immediate area between the magnetic body 5 and metal plate 2 arise in the long term.

The fastening device 13 serves the sealing plate 9 via one at the top and bottom of the sealing plate 9 arranged sealing ring structure 11 in the direction of the magnetic body 5 to press. The sealing ring structure 11 is formed of a single element, with a substantially U-shaped cross-section.

In the 5 embodiment shown is executed without sealing construction. In the 5 However, the embodiment shown can be provided with a sealing construction as disclosed herein, in particular, because the on the protective device 4 attached metal plate 20 too high transverse pressures and dynamic stresses (eg caused by wind) on the protective device 4 can lead, so the protection device 4 This can cause long-term damage and lose its sealing function.

In the embodiments shown in the figures, a magnetic attachment is provided by means of at least one magnetic body. The invention also includes embodiments without magnetic attachment, z. B. mounting variants according to the prior art, for. B. with penetration of the protective device. However, the weak point of penetration of the protection device and / or attachment point generally exposed to strong cross pressing forces may be protected from water, moisture, etc. by the seal construction as disclosed herein, according to one embodiment of the invention.

The invention also includes embodiments in which the base body of the mounting device and the base body of the mounting device are designed as a magnetic body, so that preferably above and below the protective device, a magnetic body can be arranged.

The invention is not limited to the preferred embodiments described above. Rather, a variety of variants and modifications is possible, which also make use of the inventive idea and therefore fall within the scope. Moreover, the invention also claims protection of the subject matter and the features of the subclaims independently of the features and claims referred to.
