Description

The invention relates to a mounting system for panels for facade cladding of buildings and for invisible fastening of the panels to profiles that are connected to a building wall are.

EP-A-0 761 904 describes a mounting system for panels for the facade cladding of Buildings. The mounting system includes profiles and U-shaped hooks, which means a fastener are connected to the plate side, the building wall is facing. Angle profiles are attached to the building wall, with the longer angle sides these profiles protrude into the space between the side walls of the hook and punched out exhibit. Through holes in the side walls and through the cutouts Pushed bolts that are fixed in their position in relation to the respective hook.

A fastening system for compact panels is from German utility model G 94 16 917.9 one or more layers of fiber that are hot-pressed together and impregnated with resin known, which are coated on at least one side with a decorative layer, for invisible mounting on a base body. The fastening system consists of one Profile that connects the compact panels and a wall or base and in the sides of the compact plates, which face the base body, are millings attached, the cross sections of which coincide with sections of the profile. The single milling consists of two mirror images arranged perpendicular to the compact plate Cross sections that run obliquely to the surface of the compact panel and an angle of Enclose 50 to 100 °. The cross sections take square sections of the Profiles on. An end piece of the profile is V-shaped, and the sections form the End sections of the V shape.

The core of compact panels has a very high strength and can therefore exert great forces record without breaking or deforming. Compact panels or similar Panels are used especially for facade and wall cladding due to their high Weather and dimensional stability used, taking care that the attachment the panels on a wall or a base body are invisible from the outside. The invisible Fastenings are realized in the prior art in such a way that the plates glued or fastened with screws. For screw connections, these are done directly with the panels, generally with the dowels in the panels. The connection with the wall behind it or with the base body behind it happens, for example over bracket.

In the prior art it is also common to have metal hooks with screws or dowels in a hole attach to the back of the panels. The plates are then hung in metal bars, which are fastened in vertical profiles, which are connected to the wall or to the building are. The bars can also be attached to adjustable facade anchors. Any of these Platten has two adjustable hooks on the upper edge and a fixed hook, known as the Fixed point is formed. The lower clasps must be higher than the lower edge of the plate can be used to allow changes in the shape of the slab and its substructure. The agraffes are generally brackets that are, for example, arched can be trained. This system involves assembly and disassembly work time-consuming, since the individual plate must be hung on a metal bar. Adjusting the plates horizontally and vertically requires laborious work on the back of the plate, which has to be suspended, for example, the metal latch in the Reposition the vertical profile or readjust when using facade anchors. Only after this adjustment work can the plate be in its new position on the facade substructure take in.

The object of the invention is to provide a mounting system that allows a quick assembly of the Plates of a facade cladding enables the number of system components to be kept low and the cost of cladding with invisible fasteners reduced.

This object is achieved in such a way that the assembly system from base profiles and connecting profiles that are horizontally attached to vertical profiles, wherein the vertical profiles are connected to the building wall, that each base profile is a U-like Cross-section, in which the farther from the building wall, upwards directed legs of the cross section shorter than the leg attached to the vertical profiles and that each connecting profile is a short, upward and downward one Has leg that is further away from the building wall than a vertical leg that with the vertical profiles is connected, one at the lower end of this vertical leg horizontal leg that connects a flexible elastic insert at its open end having.

The mounting system therefore only needs two types of profiles, namely a basic profile and a connection profile, which differ from one another in their design.

In one embodiment, the base profile consists of two different vertical legs Lengths that are connected by a horizontal leg. In another embodiment, the base profile consists of the vertical leg angled horizontal upper end, a horizontal angled from the leg Leg and a hollow profile fastened to the horizontal leg with a rectangular Cross-section. The two outer sides of the hollow profile extend more vertically Leg and horizontal leg beyond the hollow profile.

In an embodiment of the invention, an embodiment of the connection profile consists of the upward and downward legs, an upper horizontal straight leg, the vertical leg and a lower horizontal leg, the lower leg is widened like a claw at its open end and picks up the insert. This deposit points away from the building wall. The lower horizontal leg is expediently below Inclusion of its open claw-like end and the insert shorter than the upper horizontal Leg. This measure takes into account that the inside of a plate can rest against the insert and at the same time with the outside of its upper end with the Inside of the downward vertical leg of a connecting profile in contact is.

In another embodiment of the invention, the connection profile consists of the top and downward thigh, an upper horizontal, kinked thigh, the vertical leg and a lower horizontal leg, being on the lower leg a hollow profile with a rectangular cross section is attached. It is expedient that of the vertical leg facing away from the hollow profile shaped like a claw and picks up the insert.

A mounting system 1, as shown in FIGS. 8 and 9, comprises base profiles 3 and connecting profiles 5, which are horizontally attached to vertical profiles 6, which in turn with a Building wall 7 are connected as in the case of FIG. 8. With assembly system 1 you can Plates 12, 30 on the base profiles 3 and 5 connecting profiles are attached invisibly. The latter are largely covered by the arrangement of the plates on the profiles and therefore invisible to the observer of the facade cladding. 8 and 9 illustrated basic profiles 3 and connecting profiles 5 represent the preferred embodiments of the profiles, but they can also be achieved by simple basic profiles 2, as in FIG. 1 shown, and simpler connection profiles 4, as shown in Fig. 3, are replaced.

The base profile 2 shown in Fig. 1 consists of two vertical legs 8 and 9, of which the leg 8 is considerably shorter than the leg 9. The two legs 8 and 9 are connected to each other by a horizontal leg 14 which has openings 34. This base profile 2 is for example on the leg 9 by means of screws, not shown connected to the vertical profile 6 in Fig. 8. The openings 34 are used for dewatering Condensate water. The base profile 2 is at the lower end of a vertical facade cladding attached and supports the bottom panels 12 of the facade cladding.

The preferred embodiment of the basic profile is the basic profile 3 shown in FIG compared to the base profile 2 is constructed more complex. The base profile 3 has similar to that Base profile 2 has a U-like cross section and includes a vertical leg 9 angled horizontal upper end 15, one angled from the leg 9 horizontal leg 16 and a hollow profile 17 with a rectangular cross-section that to the horizontal leg 16 connects. In the vertical leg 9 there are openings 35 for attachment on the vertical profiles 6 and in the horizontal leg 16 openings 34 for drainage of condensate water. Two outer sides 18, 19 of the hollow profile 17 extend extend beyond the outer cross section of the hollow profile and sit in one vertical leg 8, which is directed upwards and a horizontal leg 20, which in Direction of the vertical leg 9 shows. In the hollow profile 17 is a during assembly Rectangular profile 36 inserted, as indicated in Fig. 2, the length of the rectangular profile 36 is dimensioned so that there are two adjacent, on the same horizontal aligned basic profiles 3.3 connects and thereby the stability of the mounting system or the facade cladding increased.

3 shows the connection profile 4, which represents a first embodiment. The Connection profile 4 consists of an upward and downward vertical leg 10, an upper horizontal, straight leg 21, a vertical leg 11 and a lower horizontal leg 22. The lower leg 22 is at its open end 26 claw-like expanded and receives an insert 13, which is made of a flexible elastic Material such as rubber, plastic or the like is made. The connection profile 4 is such designed that the lower horizontal leg 22 together with its open claw-like end 26th and the insert 13 protruding from the end 26 is shorter than the upper horizontal leg 21 is. This configuration in cooperation with the profiling of the plates 12 and 30 the facade cladding ensures a secure attachment of the panels and the simultaneous Cover the connecting profile 4 through the plates, so that the profile from the outside of the Facade cladding remains invisible, as is still the case with the 8 and 9 will be described in more detail. Openings 35 are in the vertical leg 11 provided for attachment to the vertical profiles 6. The vertical leg 11 is by means of Screws, not shown, connected to the vertical profiles 6 of the mounting system 1.

The connection profile 5 according to FIG. 4a represents a second, preferred embodiment and includes the upward and downward vertical leg 10, an upper one horizontal bent leg 23, the vertical leg 11 and a lower horizontal Leg 24. This is followed by a hollow profile 25 with a rectangular cross section. in the Vertical legs 11 are openings 35 for attachment to the vertical profiles 6. In a modification of FIG. 4a, the vertical leg 11 is dimensioned thicker than the legs 10 and 24. Furthermore, the upper leg 23 is braced obliquely on its underside, the is called he has an oblique underside that does not have the kink of the top of the leg 23, as Fig. 4b shows. 8 and 9 show how this connecting profile 5 is used to two plates 12 and 30 arranged vertically one above the other connect. An outer side 27 of the hollow profile 25 facing away from the vertical leg 11 is claw-like shape and receives the insert 13. Even in the second embodiment applies that the lower horizontal leg 24 together with the hollow profile 25th and the projecting insert 13 is shorter than the upper horizontal, bent leg 23. A rectangular profile 37, which is dimensioned in this way, is inserted into the hollow profile 25 during assembly is that its length is sufficient, two adjacent, aligned on the same horizontal Profiles 5, 5 to connect with each other and thereby the stability of the mounting system or to increase the facade cladding.

A comparison of the first and the second embodiment of the base profiles 2, as well the comparison of the first and second embodiment of the connection profiles 4, 5 recognize, that the second embodiments are essentially only by the additional hollow profiles 17, 25 differ from the first embodiments. These hollow profiles 17, 25 have the advantage that rectangular profiles 36 or 37 can be inserted into them, connect the neighboring base or connection profiles with each other and thereby the Increase the stability of the mounting system or the facade cladding.

5 shows a longitudinal section through the panels 12 and 30 of the facade cladding. It should be noted that both in the bottom horizontal row of the facade cladding attached plates 12 and arranged in rows above Plates 30 have the same shape. Each of the plates 12, 30 is cut and cut at the top has a web 31 which has a thickness of 2 to 4 mm and a length of 12 to 18 mm having. The thickness D of the plates is in the range of 8 to 16 mm, the height is 200 to 1200 mm. The web 31 arises as a result of an incision at the upper end of the plate 12 or 30, such that a base 47 of the incision extends obliquely to a wall of the web 31 and includes an angle α> 90 °, in particular in the range from 100 to 105 °. On the Underside of the plate 12 or 30 is also an incision 28 or 32, at least has a thickness of 4 to 5 mm and a length of 14 to 18 mm. This cut 28 and 32 is equipped with a groove 29 and 33, which have a width of at least 1.6 up to 2 mm and a depth of at least 3 to 4 mm. 5 to the right of this groove 29 or 33 located material thickness of the plate 12 or 30 is equal to the thickness of the web 31st The web 31 is located on the inside or back of the plate 12, 30 of the facade cladding ,

The sectional top view in Fig. 6 shows two panels 12a, which are spaced apart by a joint a are spaced. Each of the plates 12a has a groove 46 into which a connecting plate 42 is inserted. This connecting plate 42 is preferably a metal plate such as an aluminum plate with a thickness of 2 to 3 mm accordingly the thickness of the groove 46 and a width of 30 to 40 mm.

Fig. 7 also shows a sectional plan view of two interconnected plates 12b, 12b of the facade cladding. The right plate 12b in this plan view has one Incision 44, while the left plate 12b has an incision 45 which is less deep than the incision is 44. The incision 44 of the right plate 12b leaves a plate web 43. The two plates 12b, 12b are pushed together in such a way that the plate web 43 is in contact with the left panel 12b, with a gap b between the two panels remains. On the back or inside of the plates, which points upwards in FIG. 7, there is one Panel joint c between the two panels 12b, 12b.

The sectional view of Fig. 8 shows a facade cladding that using the Assembly system 1 is created. The bottom row of panels 12 is with the base profiles 3 in the way that the short vertical leg 8 of the base profile 3 in the groove 29 of the Plates 12 engages. The bottom plates 12 completely cover the base profiles 3. There is a gap between the lower edge of the plates 12 and the floor, due to the supply air A flows in according to the arrow that flows up along the inside of the facade cladding and exits as exhaust air B at the upper end of the facade cladding. The connection profiles 5 add the bottom panels 12 with the panels 30 vertically above them in the manner together that the inserts 13 of the connecting profiles 5 on the inside of the plates 12 and the webs 31 on the tops of these plates 12 on the inside of the downward facing Legs 10 of the connecting profiles 5 rest. The upward facing parts of the short vertical legs 10 of the connecting profiles 5 engage in the groove 33 on the undersides of the Plates 30 a. The plates 30 have incisions on the inside, which leave webs, which completely cover the legs 10 of the connecting profiles on the outside. The upper end profiles of the facade cladding are also connection profiles 5, whose vertical legs 10 are not covered on the outside. The webs 31 of the Plates 30 rest on the inner sides of the legs 10. Both the basic profiles 3 and Connection profiles 5 used as end profiles are each in a certain Distance from the floor or from the ceiling arranged so that there is sufficient air circulation and thus ventilation of the facade cladding is ensured.

The facade cladding is installed in a series of steps. In the first step the vertical profiles 6 are attached to the building wall 7. In a second step the base profiles 2 and 3 are aligned horizontally on the vertical profiles. The Distance between these profiles depends on the width and height of the to be installed Panels or panels. In the third step, the connecting profiles 4, 5 are adjusted and on the vertical profiles 6 attached. The fourth step is in the middle of the profiling on the A small amount of adhesive is applied to the underside of each plate, i.e. every plate comes with glued to the profile underneath, for one-sided displacement to the left or right to prevent beyond the horizontally aligned profiles. In the fifth step, the The top of the panels first engage with the connecting profiles above 4 or 5 and then down until it engages with the connection profiles underneath pushed. This will prevent the panels from being pulled out due to Wind created negative pressure or by the action of other mechanical forces secured and also covered the connection profiles so that they from the outside the facade cladding are invisible. Fig. 8 shows a facade cladding like this is preferably used for interior wall cladding.

FIG. 9 shows a facade cladding similar to that according to FIG. 8. At a distance of the building wall 7 is a structure or a vertical profile 6, for example made of wood or Aluminum fastened. There is thermal insulation 41 between the structures further corner pieces 48 are provided, with which a horizontally oriented end panel 49 is attached to the structure. The connection between lower and upper plates 12 or 30 takes place via the connection profiles 5. The completion of the facade cladding also form connection profiles 5. A cross member 38 is above the facade cladding attached and is covered by an angular cover 39. The cross member 38 is for example, let one end into the housing wall 7. Between thermal insulation 41 and profiles 3 and 5 there is a duct through which the supply air A and Flow exhaust air B to ventilate the facade cladding. The bottom of the Facade cladding closes the L-shaped cover panel 49 with openings 40 in the longer one the two legs that run horizontally, while the shorter leg on the housing wall 7 is attached. The longer leg of the end panel 49 connects seamlessly to the Base profiles 3 and its openings 40 serve to drain condensate water.
