  • radar systems such protective coverings often have the shape of a dome and are referred to as radomes.
  • Such protective coverings should generally have a low absorption behavior for the electromagnetic radiation of the respective radio or radar system. As a result, the attenuation of the signal intensity of the electromagnetic radiation through the protective covering is only slight.
  • FIG. 11 It is known to produce protective coverings of this type from a rigid polyurethane (PUR) foam.

  • the resulting joints 24 are foamed with the aid of formwork 23 with hardening foam so as to connect the components 21,22 together. Since the components 21, 22 are self-supporting, they must have a certain stability so that the material of which they are made typically has a density of 200 kg / m 3 to 250 kg / m 3 .
  • a disadvantage of such protective coverings is that they tend to crack formation under strong temperature fluctuations and easily accumulates on the surface of the protective covering ice and snow. The weight of the ice and snow can pose a certain risk of collapse for the fairing.
  • the object of the present invention is therefore to provide a component and a protective covering as well as the respective production methods with which a simple assembly of the components to form a protective lining is possible.

  • the component according to the invention has a support element which is provided on one side of the hard foam layer.
  • the support element essentially assumes the supporting or self-supporting task of the component, so that the insulation layer can be optimized with respect to other criteria than the supporting function. For example, it is possible to optimize the insulation layer with respect to the insulating property. This makes it possible to improve the insulation properties so that can be largely dispensed within the protective cover on air conditioning, heating or cooling. Furthermore, it is possible to provide the insulating layer with a low density, so that overall the weight of the components kept as low as possible who can. The low weight is a great advantage for the assembly because it eliminates the need for cranes.
  • the insulation layer may be made of a rigid foam, for example.
  • An example of this is polyurethane (PUR) foam.

Characterized in that the support element over the entire surface of the insulating layer is provided, thus results in a homogeneous absorption of the in / out of the protective cover / exiting electromagnetic radiation. Furthermore, it is advantageous for the stability of the component when the support element extends over the entire surface of one side of the insulation layer.
  • a particularly advantageous embodiment of the component according to the invention results from the fact that the component and / or the support element and / or the insulation layer tapers towards the ends of the component.
  • the taper By the taper, it is possible to connect the components together so that no bead or such forms after connecting two adjacent components at the junction.
  • the space obtained by the taper can thus be used to connect the components.
  • This makes it possible to have a smooth, i. To obtain a bead-free surface, on the ice and snow on the surface can slip well, so that the protective cover is not loaded.
  • the taper of the component can be realized both by a taper of the support element, as well as by a taper of the insulating layer or a combination of the two.

  • a further particularly advantageous embodiment of the invention consists in that the component has slots on one side, wherein the side is preferably the side opposite the support element.
  • the slots may extend into the insulating layer and also form slots in the support member.
  • the slitting of the component on one side results in the component being able to be curved by the action of an external force, so that even with a component that was flat prior to the slitting, it can be used to produce curved protective coatings.

  • Particularly advantageous in this case is the production of the support element or the insulating layer in a component form.
  • This smooth surface is of great advantage for the protective covering which is produced with such a component, since ice and snow can thereby slide down on the surface of the component and thus on the surface of the protective covering and do not remain exposed on the surface.
  • a component form is advantageous in order to predetermine the outer shape of the component during manufacture.
  • a subsequent aftertreatment for example by cutting or sawing, in order to achieve a desired outer geometry of the component is therefore not necessary.

A large number of components 1 is advantageous in this case, since then the angles at which the components 1 abut one another become approximately 180 °.
  • the support member 2 of the components 1 on the outside of the protective cover.
  • the outside can be very smooth, resulting in a very smooth outer surface of the protective covering. This allows ice and snow to slip well on the fairing and the weight that the protective fairing 17, 18, 19 must hold is not very large.
  • FIG Fig. 10 The manner in which it is possible according to the invention to join the various components 1 to the protective coverings 17, 18 or 19 is shown in FIG Fig. 10 shown.
  • the components 1 comprise the insulating layer 3 and, in the in Fig. 10 shown embodiment, respectively, an upper and an optional lower support element 2.
  • the two workpieces 1 are each provided with a taper 7 at the ends facing each other.
  • the taper 7 is realized here by the taper 7 of the support element 2, but can also, as shown above, additionally or exclusively by tapering 7 of the insulation layer 3 can be achieved.
  • the components 1 are shown slightly spaced. However, the components 1 can also completely meet, so that the connecting means 16 is present only in the resulting cavities between the two components 1.
  • the connecting means 16 may, for. B. be the same material from which the insulation layer 3 was made. Particularly suitable is the PUR foam, which is available for on-site assembly in pressure cans.
  • the extension of the connecting means 16 upwards or downwards is preferably equal to the layer thickness of the insulating layer 3, but may also include the thickness of the insulating layer 3 plus the thickness of the supporting element (s) 2 at the ends. Other dimensions are possible according to the invention.
  • the connecting means 16 In the event that the material of the connecting means 16 is equal to the insulating layer 3, and also in the case that the extension of the connecting means 16 along the thickness of the components 1 is equal to the thickness of the insulating layer 3, thus results in a continuous area, which is made of one and the same material with one and the same layer thickness and thus a completely homogeneous absorption with respect to the electromagnetic radiation of the radio system.
  • other connecting means 16 than the material of the insulating layer 3 and other dimensions along the thickness of the component 1 of the connecting means 16 can also be selected.
  • the connecting means 16 may also be omitted according to the invention, since the components can also be connected to one another at their outer / inner side.
  • this empty space 15 can now be filled with connecting material in order to establish the connection between the components 1.
  • the empty space 15 is preferably filled with the material from which the support element 2 of the components 1 was produced. This has the advantage that the absorption of the electromagnetic radiation in the region of the connection is the same as in the region of the components 1.
  • the thickness of the material in the region 15 may be greater / smaller than the layer thickness of the support element 2 of the components 1.
  • a protective covering 17,18,19 for a radio system as in Fig. 7a is shown, already curved components 1, as in Fig. 6c and 6d shown used. It is also possible slotted components 1, as in Fig. 1b, 1c . 4d and 5b shown to use.
  • the slotted components 1 are curved by the action of an external force, in one direction, so that the slits 14 lie on the curvature inside and thus at least partially close.
  • the components 1 are assembled with a connection technique which will be described later. It is advantageous here to assemble the protective covering 17, 18, 19 from a plurality of individual components 1. Thereby, the weight of the components 1 can be kept in a range which makes it possible to mount the components 1 solely with human power, ie in particular without cranes. Thus, protective coverings with several meters or several tens of meters can be built.
  • a protective cover 18 for a radio system as in Fig. 8a and 8b can be shown, planar components 1, as shown in Fig. 4c and 5a are shown used.
  • the ends of the components 1 will be provided obliquely angled.
  • FIG. 9 For protective panels 19 in the form of a dome, as in FIG. 9 can be shown, advantageously components 1 of the type Fig. 1c be used, since a curvature in different directions at different points of the component 1 is possible.
  • the other components 1 from the FIGS. 1a, 1b . 4c, 4d . 5a, 5b . 6c, 6d can be used.
  • the components 1 of a protective cover 17, 18, 19 are assembled with the connection technique described below to form a protective cover 17, 18, 19.
  • the components 1 are supported and held by appropriate devices or by hand at their predetermined place.
  • a connecting means 16, e.g. PUR foam is injected into the space between the blunt ends of the components 1. It glues there with the ends of the components 1 and connects them firmly after curing.
  • connection means 16 it is also possible according to the invention to first provide a surface, which abuts a component 1 to be assembled, with the connection means 16, then to insert the component 1 to be mounted and to let the connection means 16 dry or harden.
  • the components 1 can thereby abut each other directly or even slightly spaced apart from each other.
  • the connecting means 16 is optional, since the components 1 are also connected to one another by the step described below.
  • the connecting material is applied, from which the support member 2 of the components 1 has been prepared. If tapers 7 are provided at the ends of the components 1, the application takes place in the space 15 created by the taper 7. If the support element 2 of the components 1 is made of fiberglass, the connecting material will advantageously also be fiberglass.
  • the GRP is applied by applying thermosetting plastic resin and glass fibers in the form of mats or fabric. The plastic resin is advantageously colored with color particles, so that after joining the components 1, a uniform outer color or color scheme of the protective panel 17,18,19 results.
  • the GRP material adheres to the components 1 outside and / or inside, hardens and connects the components 1 with each other so. On the outside, a smooth coherent layer of the material from which the support elements 2 of the components 1 are made is ideally obtained.
  • connection of the components 1 can also take place on the inside of the protective covering 17,18,19. This is particularly useful if support elements 2 of the components 1 are also provided on the inside.
  • connection with the connecting material in the voids 15 need not necessarily occur. However, it would then be advantageous to seal the joints between the support elements 2 of the various components 1, at least on the outside of the protective cover 17, 18, 19.
  • the sealing can be done with suitable sealing materials or with a material from which the support elements 2 of the components 1, eg GRP or even just e.g. Polyestherharz are made.
  • the components 1 according to the invention and the connection technology according to the invention it is possible to provide a protective covering 17, 18, 19 according to the invention whose absorption in the region of the connection points is virtually identical to the absorption of the components 1 in a region outside the connection points.
  • the finished protective cover 17,18,19 may have a smooth surface on the ice and snow slip well. Due to the good insulation properties are special heating, cooling, or air conditioning systems for the interior of the protective cover 17,18,19 in which the radio system is located, not or only with very low power necessary.
