    The invention relates to a flat protective plate (1, 1a-b) intended to be joined to such protective plates to form a protective covering which is transparent to electromagnetic radiation. The protective covering is intended to be arranged on floors and walls in a room and the protective plate comprises recesses (3) against the support surface so that the protective plate is kept separate from the support surface. This means that water vapor from the walls can be transported away from the space behind the protective plates. In one embodiment, the protective plate has recessed receiving strips (2) along two adjacent sides intended to receive an adjacent protective plate. The invention also relates to a protective cover (1, 1a-e) with such protective plates (1, 1a-b), angled protective plates (1c-d) and corner elements (1c). In one embodiment, the protective cover forms a continuous container with an open bottom, where the protective cover in its roof part comprises a single fl (7). The protective cover does not extend all the way to the floor, so that water vapor can pass along the lower edge of the protective cover. ll / ll

    the protective plates. Sealings can advantageously be achieved by pressing so that they form a continuous part of the protective plate.
    In a particularly advantageous embodiment, the protective plate has recessed receiving strips 2 recessed along two adjacent sides, intended to receive an adjacent protective plate. The receptacles are recessed from the main part of the protective plate in the same direction as the recesses 3, but the receptacles are not recessed as deep as the recesses 3, so that the receptacles do not block the transport of water vapor.
    The invention furthermore relates to a protective covering 1, 1a-e which at least comprises such a protective plate 1, 1a-b. The protective plates are intended to be welded together along at least one receiving strip 2 and the risk of the weld joint not becoming sealed is considerably reduced compared with welded joints between commonly designed protective plates.
    The protective upholstery may in addition comprise angled protection plates 1c-d and corner elements 1c, provided with recessed receiving strips 2, 2a-f. In a particularly advantageous embodiment, the protective cover forms a continuous container with an open bottom, the protective cover in its roof part comprising an opening 9 which is transparent to electromagnetic radiation with a true fl.
    In a particularly advantageous embodiment, the protective cover forms a continuous container with an open bottom, where the protective cover is arranged in a room with a floor and where the protective cover does not extend all the way to the floor, so that water vapor can pass out at the lower edge of the protective cover.
    Brief description of the figures Fig. 1 shows a first embodiment of the protection plate Fig. 2 shows the first embodiment of the protection plate in cross section Fig. 3 shows a recess in the protection plate Fig. 4 shows the recess in cross section Fig. 5 shows a weld on a protection plate according to known technology Fig. 6 shows a welding joint on a protective plate according to the invention Fig. 7 shows a second embodiment of the protective plate Fig. 8 shows a third embodiment of the protective plate Fig. 9 shows protective plate cladding for a room Fig. 10 shows a corner element in protective plate Fig. 11 shows description of preferred embodiments Fig. 1 shows a first embodiment of the protection plate 1a which consists of a metal plate, typically in aluminum, with a substantially rectangular shape. The protective plate is almost completely opaque to electromagnetic radiation in a wide wavelength range and is intended to attenuate the transmission of such radiation through the protective plate. Reception strips 2a-b extend along two adjacent sides and corresponding strips are missing along the two remaining sides. When a room is to be covered with a protective plate, such protective plates are placed side by side next to each other so that the listless side of a protective plate is placed on a receiving plate's receiving strip for welding. In this way, a mechanically cohesive metal surface is achieved with electrical connection between each adjacent protective plate element. Over the surface of the protective plate, recesses 3 are distributed in a grid pattern. In the middle of the recesses is a screw heel 4 which is used to attach the protective plate to a wall. The recesses hold the protective plate in position a distance from the underlying wall, which enables water vapor to leave the space behind the protective plate. Water vapor behind the protective plates would otherwise have been able to condense more easily and in the more humid environment is formed as lighter mold and the plate can oxidize.
    Protective plates are often placed on an underlying concrete wall that has not yet hardened completely and the wall then emits large amounts of water vapor which, with the help of the recesses, is more easily transported away behind the protective plates. The recesses with the screw holes can easily be achieved by pressing.
    Fig. 2 shows the first embodiment of the protective plate in cross section and here the depression 3 is more clearly illustrated with the central screw hole 4. The depression extends a distance from the rear surface of the protective plate and the protective plate is intended to be mounted against a wall below the plate. , that is, on the side to which the recess extends.
    The recess has a flat bottom part which gives an arched surface which lies against the wall and keeps the main part of the underside of the protective plate separated from the wall surface.
    At one end of the protection plate, a receiving strip 2 is illustrated in cross section, which consists of a recessed portion of the protection plate along one edge thereof. The receiving strip is shallower recessed than the recess 3 so that the protective plate does not even reach the wall at the receiving strip. The receiving strip is countersunk on its upper side a plate thickness to receive on its upper side an adjacent protective plate.
    The edge of the adjacent protective plate received on the receiving strip looks like the other edge 6 of the illustrated protective plate on the right side of the fi clock. The other edge is obliquely cut on its lower side to fit against the curved part of the receiving strip, but the edge can also be straight cut.
    Fig. 3 shows a depression in the protective plate in greater detail and fi g. Fig. 4 shows the same recess in cross section along the section A-A in Fig. 3. The figures more clearly illustrate how the recess is circular with conically inclined sides which run over into a flat, circular middle part whose underside abuts against the wall to which the protection plate is to be attached. In the center of the flat, circular middle part, a through-hole hole 4 is arranged. Obviously, the screw holes are not exclusively intended for fastening with just a screw, but other alternatives are conceivable and completely different fastening methods can also be used.
    Figs. 5 and 6 show the difference between welding joints on protective plates according to known technology and according to the invention for comparison. When joining, high demands are placed on the welding joint to provide electrical connection between adjacent protective plates over the entire length of the joint in order to achieve optimal damping of electromagnetic disturbances. In addition, the weld joint also has a mechanical cohesive effect that is more easily achieved with protective plates according to the invention.
    F ig. 5 shows a welding joint on a protection plate according to the prior art where two protection plates with straight beveled edges abut each other edge to edge. A weld has been laid along the edge which is intended to connect the two protective plates to each other, but in unfortunate circumstances the weld can lie over at least part of the edge so that it only touches one plate or leaves a thin layer of air between them. In such a crack, oxide can then be built up so that the two protective plates along a portion of the edge do not come into electrical contact with each other. This makes the protective plates less attenuated by interfering electromagnetic radiation which the protective plates are intended to stop.
    Fig. 6 shows a weld joint 5 between two protective plates 1a-b according to the invention. The weld joint lies in the receiving strip 2 on one protective plate 1a and thus extends over a larger width than is possible with weld joints according to known technology. The weld joint also abuts against the edge of the second protective plate which lacks a receiving strip and extends over the entire edge surface. This is in contrast to the weld on the protective plates according to the prior art, where the weld only reaches part of the thickness of the edge of the plate, so the weld has better possibilities of achieving a consistent electrical contact between the edges of the protective plates than is possible with protective plates according to the prior art.
    Figs. 7 and 8 show a second and third embodiment of the protective plate intended for a corner between two wall portions angled towards each other, i.e. angled protective plates. These angular portions can often be quite short and normally connect to mainly flat, adjacent protective plates which extend over flat wall portions. These flat protection plates are kept at a suitable distance from the wall with recesses, so that the angled protection plates also end up at a distance from the wall. The figure therefore shows such angled protection plates without countersinks, but of course there is nothing to prevent these angled elements from also being provided with countersinks. From the fi gures, the welds have also been eliminated for the sake of clarity, so the protective plates are thus illustrated as they look before the weld is laid there.
    Fig. 7 shows the second embodiment of the angled protection plate 1c in cross section. The second embodiment is intended for inner corners on the wall and the protective plate is provided along its one edge with a recessed receiving strip 2 which receives one adjacent, substantially flat, protective plate. As in the first embodiment, the receiving strip 2 is recessed against the wall, but does not reach it because the recesses are deeper.
    Fig. 8 shows the third embodiment of the angled protection plate 1d in cross section. The third embodiment is intended for outer corners on the wall and the protective plate is provided along its one edge with a recessed receiving strip 2 which receives one adjacent, substantially flat, protective plate. As in the first embodiment, the receiving strip 2 is recessed against the wall.
    Fig. 9 shows protection plate enclosure for a room consisting of a number of substantially flat protection plates which are joined to adjacent protection plates, either another such substantially flat protection plate, an angled protection plate lc, d or a corner element le. These form an electrically completely closed container upwards and to the sides. Typically, the floor is left without a sheet metal because facilities that involve highly interfering electromagnetic fields are often placed underground on the lowest level of a building and the ground under the building prevents electromagnetic fields from spreading downwards through the ground. Obviously, a room can alternatively be completely sealed with such protective plates. To simplify the terininology in the requirements, walls refer to actual walls, floors and ceilings.
    Fig. 10 shows a corner element in protective plate which comprises three flat protective plate pieces which extend in the x-, y- and z-plane respectively and are connected to each other along two edges. Each piece of protective plate exposes two free edges and on each of these there are recessed receiving strips 2a-f which are intended to receive the edge of an angled protective plate. The corner element will also form a continuous part of the protection plates after welding and is considered here as a protection plate, although this special element is not necessarily made of pressed or bent plate but can be cast or manufactured in another way.
    In the same way as the angled protection plates, the corner elements normally connect to adjacent protection plates which are kept directly or indirectly at a suitable distance from the wall with recesses, so that the corner elements thus also end up at a certain distance from the wall. The figure therefore shows the corner element without depressions, but of course nothing prevents the corner elements from also being provided with depressions.
    Fig. 11 shows in cross section a room clad in protective plates 1 which together form a continuous protective covering. Of the room, only walls 6 and ceilings are illustrated because the protective plates do not intentionally reach all the way down to the floor. This leaves a downward opening along the entire lower edge of the protective cover where water vapor can be transported away from the space between the protective cover and the wall.
    To further streamline the ventilation behind the protective plates, the protective cover here is provided with a fl that blows in air centrally on the protective cover so the air tends to flow slowly behind all the protective plates. In order to prevent electromagnetic radiation from leaking out at the opening where the fl spigot is arranged, the fl spigot is surrounded on the room side by a completely non-transparent housing for electromagnetic radiation which still lets air through. The housing comprises side walls 8 which can be made of protective plates of the same type as other protective plates in the protective clothing, such as a filter 9 through which air can flow. The filter can be made of metal mesh, metal wool or similar electrically conductive but air-permeable material.
