Element for the fastening of devices or objects on an externally insulated façade

0001The present invention relates to an element according to the preamble of claim 1.

0002It is known in buildings, ceilings and / or walls by means of Thermal insulation boards made of foam or the like. As cold protection isolate. The thickness of such insulation is usually 80 to 160 millimeters. In building facades, for example, be on the cut brickwork, predominantly or in the case of the Nachisolation purified old render the insulation boards glued seamlessly and with mushroom-shaped plastic nails on masonry additional mechanical attached. After a network is on the board outside mounted and adhered with a basic plaster-like adhesive. After the setting or curing these basic plaster-like adhesive layer the finished plaster is applied. A disadvantage of this external insulation is that, on the plasterwork no lights, sensors Coat hooks, bolts for shutters, clamps for water pipes and roof water drainage pipes, house numbers, etc. with normal Plugs and screws are fastened. Are such items facade side to mount, wooden blocks are first in the recessed insulation layer, bolted to the masonry and then the subject of the block of wood screwed. It is also known, long, the insulation layer penetrating screws use the embedded with the tip in a masonry Anchors are screwed. The durability of the mentioned Chumps however, is not guaranteed, since it in the water vapor condensation zone the wall are, therefore, are often wet and over time can rot. Access to more than long Mounted screws facilities occasionally transverse to Screw axis oriented forces of different sizes, the screw turn to different degrees and enlarged gradually their passing through the plaster and the insulation hole one in the water and gradually penetrate behind the insulation can.

0003Similar problems arise when on an insulated facade electrical switches, sockets or the like. are to be mounted as the intake box on which such devices are mounted in the insulating layer only insufficient support and with Loosen the time.

0004For a more stable attachment of the intake box in the insulation layer is known, two L-shaped angle pieces symmetrically and spaced apart screwed onto the masonry and cut to length between the parallel, to the thickness of the insulating layer Legs a mounting box to fix. This procedure improves the stability of the built-mounting box. Satisfying is not it, however. Moreover, the mounting of the angle pieces costly in terms of their specific mutual position.

0005The present invention therefore has as its object, a to provide means which is easy to handle and a reliable fastening objects, appliances and the like. to allows a façade with external insulation.

0006With the accompanying schematic drawing, the invention for example, explained.

0007The element according to FIGS. 1 to 4 comprises an anchoring plate 1 with slotted holes 2 in the corners. Right angles from the Center anchor plate 1 projects a on its front tubular member 3 away, of one piece with the board 1 is made. The carrier 3 closes with its internal cross-section flush with an opening 4 in the plate 1 (FIG. 4), so that the end of the installation tube 5 of the back of the Plate 1 is pushed into the carrier 3 into and through can be. The carrier 3 has a square cross-section Hollow section with two opposing, broken Edge. The length of the beam 3 is, as with two dashed Lines shown in Fig. 2 by means of a saw or a knife Can be cut to any desired length. Next, the element a honeycomb-shaped support plate 6, on whose perforated Front the to be mounted on a wall or objects Apparatuses are screwed tight. The after the front open, checkerboard juxtaposed cells 7 are located perpendicularly intersecting, 1 to 2 millimeters thick cell walls 8 educated. At an opening 9 in the center of the support plate 6 includes a rear intake box 10, whose lights Cross-section equal to that of the opening 9 is. The side walls the intake box 10 are squeezable wall sections 12, through which, if necessary, a conduit 5 can be introduced. At the intake box 10 includes a sleeve-shaped guide 13, which open towards the intake box 10 is. The internal cross section of the guide 13 corresponds to the outer cross-section the support 3 so that it virtually without play in the guide 13 is hineinschiebbar. The carrier 3 and the lead 13 can thus telescoped domestic and apart will. On the outside, the guide 13 is axially parallel with two Ribs 14 provided, which form a groove 15th At any Location of this groove 15 is radial to the longitudinal axis of the tip guide a screw 16 self-tapping screw. The Support plate 6, the intake box 10 and the lead 13 are (Such as the anchoring plate 1 and the support 3) in one piece from a verrottungsresistenten plastic.

0008Is a façade insulated externally, will be at each location on the an object (lamp, sensor, folding hooks for clothes, etc.) is secure, an anchor plate 10 on the Rohmauer means Screws (Fig. 3). Corresponding to the thickness "d" of the Insulating layer 17, the free end of the carrier 3 so far separated, that if the plug guide 13 be shortened End in the region of the transition from the guide 13 to the intake box 10, and the distance the front of the mounting plate 6 from the Rohmauer approximately to the thickness "d" of insulating layer 17 corresponds. In this einjustierten position of the guide 13 the carrier 3 is the screw 16 on and through the wall of Guide 13 and through the carrier 3 is screwed, so that a fixed, positive connection between these two parts (3, 13) is formed.

0009Is on the support plate 6, an electric apparatus such as to fix a lamp is to this point, a conduit 5 postponed. The tube end is before screwing the Anchor plate 1 from the rear side by the carrier 3 and the lead 13 is pushed through. After fastening the Anchor plate 1, the protruding into the inlet box 10 Tube end cut off. However, it is also possible in a a wall slot Threaded conduit 5 (in FIG. 3 dash-dotted lines drawn) from the outside through a broken Wall section 12 passes to lead into the inlet box 10th

0010Thereafter, the insulation layer 17 is attached to the Rohmauer, being made to the assembled element corresponding recesses are cut out of the foam, so that no cold bridge arises. After attaching the insulating layer 17 is its Outside flush with the outside of the carrier plate 6. On the insulating layer 17 and the support plate 6 are thereafter a Haftputz 18 and then mounted a finished plaster 19th After this Curing of the finished plaster 19, the lamp in front of the carrier plate 6 placed on the facade and by the plaster layers 18, 19 through screwed into the support plate 6 screws be attached. In this structure, the cells 7 of the support plate 6 the function of dowels.

0011In the example of FIGS. 5 and 6 same reference numbers designate the same parts as in the example according to FIGS. 1 to 4, is omitted their repetitive description. The main difference is the one hand, that the Intake box 10 both in terms of depth and clear cross-section considerably larger than in the example described above is. On the other hand, the cross-sectional area of ​​the carrier plate 6 is smaller and, together with the intake box 10 together in shape and Size a conventional intake box. As chained lines indicated, both the support plate 6 and the intake box 13 doubled or tripled when facade outer side to install two or three switches and / or outlets are.

0012According to an embodiment not shown, the Guide 13 and the intake box 10 the same internal cross-section exhibit.

0013It is also possible, the guide 13 with the anchor plate 1 on the one hand and the carrier 3 to the carrier plate 6 on the other hand integrally to manufacture.

0014The cross-sections of the carrier 3 and the guide 13 may also be cross-shaped. Have the carrier 3 and the lead 13 a circular cross section, allows for the length adjustment of the Element a on the carrier 3, a foreign and on the guide 13 be provided internal threads.

0015If the item is only for attaching non-electrical equipment, like hanger, bolts for shutters, company signs and the like. provided, as shown in FIG. 7, the aperture 9 in the carrier plate 6 omitted.

0016Although the element as a carrier for fastening objects is described on an outer facade, it can also only to their protection to high impact risk facade points be used. In this case, the carrier plate 6 is preferably configured substantially larger, with more elements ranked the impact vulnerable areas nationwide each other will.
