Description

The invention relates to a holding device for a lightning protection system's air terminal, a lightning protection system with such a holding device, and the use of a holding device for attaching an air terminal. A lightning protection system diverts and carries away the lightning current from a protected object, such as a building, in the event of a lightning strike. This reduces or prevents damage to the protected object. Standard roof and facade conductors of lightning protection systems are attached directly to the structure to be protected using a bracket. This presents the challenge of attaching the bracket to uneven surfaces, such as corrugated or trapezoidal sheet metal roofs. It is known that in such application scenarios the bracket is attached to the surface using screws or rivets, or that additional bracket bases are attached between components of the respective surface, for example elements of a roof system. The GB 2 427 313 A Disclosing a holding device for a lightning conductor, comprising a flexible base element made of a polymer, which is attached to a roof via an adhesive layer. A mounting boss is also provided, to which a retaining element is attached via a bolt, which in turn secures the lightning conductor. The DE 88 01 511 U1 This describes a clamping support for lightning conductor wires for attachment to flat, overlapping roof coverings. The clamping support has a flat rail and a clamping holder attached to it. The top surface of the flat rail has a roughened texture. From the DE 10 2010 064 060 A1 A holder for attaching components of an aircraft or spacecraft, particularly to structural elements, is known. The holder may have an adhesive mount that is bonded to the structural element via flexible connection sections, whereby the surfaces to be bonded may be roughened. The DE 93 05 826 U1 reveals a size-adjustable ridge conductor holder with a flexible bracket that grips the ridge tile at one end via a hook and has several hooks at the opposite end that can be bent inwards to also grip the ridge tile. However, all these solutions have in common that they involve a high level of effort, require the use of tools and/or can represent starting points for damage to the respective surface, such as leaks. Furthermore, there are known mounts that have an adhesive pad for attaching the mount, such as in the... US 2015/0014015 A1 As described. However, such solutions are only suitable for attaching the bracket to specific surfaces, namely flat surfaces, so that the adhesive pad has a large contact area. Use on rough surfaces or corrugated and trapezoidal sheet metal roofs is not possible with these brackets. The object of the invention is to enable the flexible installation of a lightning protection system's air terminal, particularly without tools. The problem is solved according to the invention by a holding device for a lightning protection system's air terminal, comprising a holding section for receiving the air terminal and a mounting section for attaching the holding device to an uneven surface. At least the mounting section of the holding device is designed to be deformable, so that it can be adapted to the contour of the surface. The mounting section has a friction area on a contact surface that interacts with the surface contour in the installed position. This friction area has a higher coefficient of friction than the holding device on the side opposite the contact surface. The friction area is provided by a single piece of material that is metallurgically bonded to the mounting section and includes a hook-and-loop fastener and/or an adhesive pad. The term "uneven surface" means that the surface not only has insignificant, material-related structures, but that the surface has a defined shape that differs from a flat surface. For example, the uneven surface has a maximum height difference of 0.1 mm to 10 cm over an area corresponding to the size of the mounting section. For example, the uneven surface is part of a facade or roof, particularly a corrugated or trapezoidal sheet metal roof. The surface can be a metal roof surface, which ches is typically designed as a corrugated metal roof or trapezoidal metal roof. In a non-inventive embodiment, the uneven surface has a maximum height difference in the range of 0.1 mm to 10 mm. In this embodiment, the uneven surface is, for example, a structured facade or roof element. In another variant, the uneven surface has a maximum height difference in the range of 1 cm to 10 cm, in particular from 1 cm to 6 cm, preferably from 2 cm to 6 cm. The invention is based on the fundamental idea of providing a holding section that can be specifically adapted to the existing contour of the uneven surface on which the holding device is to be mounted. In this way, the holding device according to the invention can be used flexibly in a wide variety of locations, eliminating the need to provide special holding devices for different locations or applications, t
