Description

The invention relates to a passage unit made of sheet metal for residential buildings. More specifically, the invention relates the edge design of a facade unit.

Facade units of the type under consideration and fastening * Devices for this are already known from DE-GM 78 27 877 and DE-OS 2 930 043, among others.

These two documents describe a facade unit, which is designed so that a substantially completely smooth facade is achieved. The two facade units according to these publications have in common that each facade unit has a planar upper surface which is the outer surface of the one Tongue is formed, which extends away from the lower and the upper short side of the facade unit. The tongues extend upward from and form an angle with the top surface. Every tongue is moreover bent at its free end in such a way that each tongue together with the associated bent section has a V-shaped cross section. The free legs of the bent sections are essentially in cross section arranged parallel to the top surface. The bent section of the upper tongue of a facade unit and the bent portion of the lower tongue of a facade unit that is closest to the first facade unit is arranged, butt against each other, whereby the tongues cooperate to form a joint which can carry vertical forces.

According to DE-OS 2 930 043, the interacting in this way Tongues also used to attach the facade units to a fastening device, which serves for this purpose.

The long sides of the facade units described in the above-mentioned publications are designed to cooperate with the long sides of adjacent facade units by having a long side each facade unit has a downwardly curved edge and the other long side of the facade unit with a substantially U-shaped groove is also formed with a portion extending from the upper surface of the facade unit is bent and folded down.

At a connection point between two adjacent facade units, the downward-curved edge is inserted into the U-shaped groove used and interacts with this.

However, such a connection can only absorb horizontal forces which are in the plane of the facade units lie. The connection is also not always completely sealed against wind and weather.

One problem that needs to be solved particularly urgently is that it should be possible by means of a connection absorb horizontal forces between the long sides of the facade units, which are perpendicular to the plane the facade units are directed. An essential requirement that such a connection fulfills is to be, consisted in the fact that the connection must be designed in such a way that the assembly of the facade units does not become more difficult in comparison to facade units which are designed for the above-mentioned known one To form connection.

The invention solves the above problem in that such a design of the long Pages of the facade units is created that one

stable, sealed connection is achieved, which Can absorb horizontal forces, regardless of their direction, when the upper surface of the facade units is in a vertical plane.

The invention thus relates to a facade unit cius Sheet metal, together with several identical facade units and fastening devices for the units of a facade cladding for residential buildings, factory buildings and forming other systems, each facade unit having a substantially flat upper section, which should represent the outer surface, and where the lower and the upper short side of the facade unit each shaped to cooperate with a fastener and from the planar upper portion each facade unit has a side edge bent downward along each of the long sides thereof; a The first of these side edges is bent in such a way that it has a U-shape in cross-section, the bottom of which U runs parallel to the top section.

The invention is characterized in that a first of the legs of the U, which is closest to the long side the facade unit is located, is bent inward over the bottom of the U, so that this leg is together with the bottom of the U forms a section with a V-shaped cross-section, that also a second of these legs of the U, the is free, is bent upwards, so that the U-shape is formed by the two legs and the bottom of the U that the second edge of the facade, which is relative opposite to the first side edge, bent fully or partially inwardly below the top portion and together with the upper section forms a substantially S-shaped section in cross-section, wherein the outer free part of the S is bent substantially parallel to the upper portion of the facade unit "

and protrudes in the direction from the long side of the facade unit, and that the free portion of the S in cross section has a length which corresponds substantially to the length of the bottom of the U, whereby after insertion a second side edge of a facade unit in a first side edge of an adjacent facade unit in such that the end of the free portion of the S is inserted into the V-shaped portion, the free portion of the S is locked against a movement perpendicular to and parallel to the bottom of the U, and thus also against such a movement Movement relative to the top surface of the facade units.

The invention is explained in more detail below, for example with reference to the drawing; it shows:

4, 5 and 9 are facade units 1, 2 made of sheet metal shown with a variety of identical units and fasteners (not shown) for the units form a facade cladding for residential buildings, factory buildings or other facilities.

Each facade unit 1, 2 has an essentially flat one Upper part 3, which is intended to represent the outer surface of an assembled facade. From the top or the From the lower short side of the facade unit 1, 2, an upper 4 and a lower tongue 5 are formed away. These Tongues 4, 5 extend upwardly from the top surface 3 so that they are at an angle with the top Form surface. The upper tongue 4 as well as the lower tongue 5 are bent at their free ends so that each

Tongue together with the associated curved section 6, 7 forms a V-shape in cross-section, as in FIG Fig. 5 shown. The free legs of the curved sections 6, 7 are parallel as seen in cross section to the upper section, which will hereinafter also be called the upper surface 3.

From the flat upper surface 3 of each facade unit form two parallel side edges 8, 9; 10, 11 the sides of the facade unit bent vertically downwards.

A first of these side edges 8; 10 is to form a U-shape 12; 13 bent in cross section, the Bottom 14; 15 of the U is parallel to the upper surface 3.

The facade units 1, 2 act with a fastening device together in such a way that the curved sections 6, 7 of the tongues with a U-shaped part (not shown) cooperate, which is attached to a house wall or the like. The curved section 6 of the upper tongue 4 of a facade unit and the bent section 7 of the lower tongue 5 of a facade unit arranged above it are used in the same U-shaped cross section as described in DE-OS 2 930 043.

4 and 9, a facade unit 1, 2 is shown, which for the sake of clarity with the adjacent facade unit connected only in the horizontal direction.

More precisely, the invention relates to the design of the lateral edges 8, 9; 10, 11 of the facade units 1, 2. according to the invention is a first leg 16; 17 of the U 12; 13, which is closest to the long side of the Facade unit 1, 2 is arranged, inward over the Bottom 14; 15 of the U bent so that the leg 16; 17th

together with the bottom 14; 15 of the U a part 1.8; 19th forms which is V-shaped in cross-section. The second leg 20; 21 the leg of the U 12; 13, which one free Leg is is bent upwards, so that the U-shape through the two legs 16, 20; T7, 21 and the floor 14; 15 of the U is shaped.

The other side edge 9; 11 of the facade unit 1,2 is fully or partially bent and shaped downwards inwardly under the upper part 3 of the facade unit 1, 2 together with the top surface portion, a portion 22; 23, the seen in cross section a substantially Has an S-shaped configuration, as can be seen from FIGS. 2 and 7, respectively. The outer free part 24; 25 of the S-shaped Section 22; 23 is bent so that it is essentially parallel to the upper section 3 of the facade unit stands. This section 24; 25 points in the direction from the long side of the facade unit. This section 24; 25 also has a length which is essentially the length of the base 14; 15 of the U corresponds.

When inserting a second side edge 9; 11 into one first side edge 8; 10 a coupling is thus brought about between the two side edges 8, 9 or 10, 11, as can be seen from FIGS. 3 and 8, respectively. Due to the design of the side margins, after inserting the free part 24; 25 of the S into the V-shaped section 18; 19 the free part 24; 25 of the S and thus two like that facade units coupled to one another against mutual movement perpendicular to and parallel to the floor 14; 15 of the U locked.

The only movement that is possible when two units are coupled together is relative movement, the perpendicular to the plane of the paper in Figs. 3 and 8

BAD ORlGIMAL

is directed. As can be seen from FIGS. 1 and 6, that part of the first side edge 8; 10, between the first leg 16; 17 of the U and the upper portion 3 of the facade unit is located, designed such that the first legs 16; 17 of the U at its end, the closest located on the upper section 3, into a section 26; 27 passes, which is essentially parallel to the upper Section lies, and in turn in a section 28; 29 passes, which is substantially perpendicular to the upper one Section 3 stands and is thereby connected to this.

It should be emphasized that when the facade units have their tongues 4 to 6 on the aforementioned U-shaped Profile are suspended, no facade unit in a direction perpendicular to the upper surface 3 of the facade unit 1, 2 can be moved. Due to the design of the side edges, all facade units are therefore relative to all adjoining facade units completely fixed or locked.

The insertion of a second page margin in a first page margin is carried out as it is with the dashed Lines in Fig. 3 is shown. The facade unit is derived from the one indicated with dashed lines Rotated position in the direction of the dashed arrows in FIG.

After attaching a facade unit to an adjacent facade unit, which is attached to the U-shaped profile is suspended, the side edges are nested, as shown in FIG. 3. The facade unit to be suspended is moved upwards relative to the already suspended facade unit, so that the tongues 4-6 after the inward turning, as shown in Fig. 3, are arranged above the U-shaped profile. After that, the after

inside rotated facade unit moved down so that it abuts the U-shaped profile.

According to a first embodiment of the invention is a middle section 30 between the outer section 24 of the S and the upper section 3 flat. This mean one Section 30 also forms an angle with the upper one Surface 30 and has a length when viewed in cross section on which the distance from the transition of the free end of the U 12 in the bottom 14 of the U to connect with the first side edge 8 to the upper section 3 of the facade unit 1 corresponds. As can be seen from FIGS. 3 and 4 is, therefore, the connection 31 between adjacent facade units 1, seen from their upper surface 3 be a minimum.

In this embodiment, the free leg 20 of the U is bent slightly outward, as shown in FIG. 1, around alternatively, to make it possible to insert a second side edge 9 into a first side edge 8.

With this embodiment of the facade units 1, an essentially completely smooth facade is achieved.

According to a second embodiment of the invention goes a middle section 31 between the outer section 24 of the S and the upper section 3 of the outer section 24 of the S into a section 32 which forms an angle with the upper section 3, and from the the latter section 32 into a section 33 which is perpendicular to the upper section 3 of the facade unit 2 stands, as can be seen from FIG.

When the facade units 2 according to this embodiment are designed, a connection 34 is formed between two adjacent facade units 2. This connection

has a width which, when viewed in cross section, is the Length of the section 32 which forms an angle with the upper surface 3.

In this embodiment, the free leg 21 of the U is preferably designed such that it is substantially is perpendicular to the bottom 15 of the U.

This embodiment of the facade units 2 is thus a facade is achieved in which each facade unit is delimited or separated by a groove or a connection J4. is fenced.

The side edges 8, 9; 10, 11 are preferably in the above-described way along the entire long sides for the flat upper section 3 of the facade units 1, 2 curved.

The embodiments explained above can of course can be modified without departing from the scope of the invention.

In addition, a significant advantage is acquired in that the side margins described above 8, 9; 10, 11 strong reinforcements of the long sides of the facade units 1; 2 represent, creating the upper section 3 of the facade units 1; 2 is held level, even when relatively considerable forces tend to to curve the upper section 3.
