- the resulting joints 24 are foamed with the help 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 from 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 are subject to strong temperature fluctuations tend to crack and form easily on the surface of the protective covering Ice and snow accumulate. The weight of the ice and snow can cause some collapse represent for the cladding.
- the object of the present invention is therefore a component and a protective covering as well as to create the respective manufacturing processes with which a simple Assembly of the components to a protective cover is possible.

- the taper 7 results in an upper and lower part of the connection point Area 15 which, as long as it is not filled, is an empty space 15.
- this empty space 15 can now be made with connecting material be filled 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 area of the connection is the same as in the area of components 1.
- the empty space 15 be filled with a connecting material, for example has a lower / higher absorption than the material of the support element 2, so the Thickness of the material in the area 15 may be larger / smaller than the layer thickness of the support element 2 of the components 1.
- connection to the components 1 can be achieved, with the possibility being only To use materials that were also used to manufacture the components 1 themselves.
- This is special for the dielectric properties of the protective covering 17, 18, 19 advantageous because there is only a slight interference or absorption of the electromagnetic Radiation from the radio system results.
- protective cladding 17, 18, 19 for a radio-technical system as described in 7a, already curved components 1, as shown in FIGS. 6c and 6d, be used. It is also possible to use slotted components 1, as in FIGS. 1b, 1c, 4d and 5b to use.
- the slotted components 1 are by action an external force curved, in one direction so that the slots 14 on the Lie inside the curvature and thus at least partially close.
- the components 1 are assembled using a connection technique described below.
- the protective covering 17, 18, 19 to consist of several individual Assemble components 1. This allows the weight of the components 1 in one area are held, which makes it possible to use the components 1 solely with human power, i.e. H. in particular without cranes. So protective coverings with several Meters or several tens of meters.
- FIGS. 8a and 8b flat components 1, as shown in FIGS. 4c and 5a, can be used become.
- the ends of the components 1 will be provided at an angle.
- Components 1 of the type from FIG. 1c can advantageously be used because a curvature in different directions at different locations of the component 1 is possible. Also the other components 1 from FIGS. 1a, 1b, 4c, 4d, 5a, 5b, 6c, 6d can be used.
- the components 1 of a protective covering 17, 18, 19 are described in the following Connection technology put together to form a protective covering 17, 18, 19.
- the components 1 are at their predetermined by appropriate devices or by hand Supported and held in place.
- the connecting means 16 it is also possible to first attach a surface to a surface to be mounted Component 1 bumps with the connecting means 16, then the one to be assembled Insert component 1 and let the connecting means 16 dry or harden.
- the components 1 can directly meet one another or can be spaced somewhat apart be composed of each other.
- the connecting means 16 is optional, however the components 1 are also connected to one another with the step described below become.
- the connecting material is applied to the outside of the protective covering 17, 18, 19, from which the support element 2 of the components 1 was produced.
- the connecting material will advantageously also be GRP.
- the GFK will by applying hardening plastic resin and glass fibers in the form of mats or Fabric applied.
- the plastic resin is advantageously colored with color particles, so that after connecting the components 1 there is a uniform external color or color design the protective cover 17,18,19 results.
- the GRP material adheres to the components 1 solid on the outside and / or inside, hardens and thus connects the components 1 to one another. On the outside ideally results in a smooth coherent layer from the Material from which the support elements 2 of the components 1 were made.
- the components 1 can also be connected on the inside of the protective cladding 17, 18, 19 occur. This is particularly useful if support elements are also on the inside 2 of the components 1 are provided.
- the Connection with the connecting material in the empty spaces 15 does not necessarily take place.
- sealing the joints between the support elements 2 would then be advantageous various components 1, at least on the outside of the protective cladding 17, 18, 19. Sealing can be done with suitable sealing materials or with one Material from which the support elements 2 of the components 1, i.e. e.g. GRP or 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 create a protective covering 17, 18, 19, its absorption in the area of the connection points is practically identical to the absorption of the Components 1 in an area outside the connection points. Furthermore, the finished Protective cover 17, 18, 19 have a smooth surface on which ice and snow slide well. Due to the good insulation properties, there are special heating, cooling or air conditioning systems for the interior of the protective cladding 17, 18, 19, in which the radio technology System is located, not necessary or only with very low outputs.
