Description

The invention relates to a profile element in particular for producing a facade cladding for buildings, which is at least peripherally made of a metallic material, at least comprising a groove portion of a length b with a groove, a spring portion of a length a with a spring and a base extending therebetween, the lying in a plane E, wherein the groove portion is made by bending over of the metallic material, and wherein the spring has a vertical distance x from the plane E of the base surface, so that the groove of a second profile element was pushed onto the spring of a first profile element. The invention also includes a facade cladding consisting of a plurality of profile elements of the aforementioned type.

Profile elements for cladding facades are known from the prior art in large numbers. For example, z. B. the DE 77 31 578 in Fig. 3 a flat facade panel, in which tongue and groove are made by forming the material of the facade panel. Between the groove and the spring area extends a base surface which lies in a plane, wherein the groove region has a certain length and the profile element has a height h. Several of these known profile elements can be to a Façade clothing to be assembled. For this purpose, the spring portion of a first facade element is inserted into the groove portion of a second facade element and in this way two facade elements are connected together. For connection to the ground z. As a substructure or a building exterior wall, the groove portion of the known profile element on a mounting edge, can be introduced into the fastener, so that the profile element can be attached to the substructure or the building exterior wall. If several profile elements are joined together, the result is a cladding that does not show any visible fasteners. The type of installation of these profiles requires a top-to-bottom installation - horizontal laying - so that there is no guarantee that the connection will be made exactly because the processor can no longer control the exact connection of the tongue and groove ,

Similar, equipped with diffusion holes profile elements are the DE 2 447 489 refer to.

Based on this problem, it is an object of the invention to provide a profile element, in which it is ensured that the connection is made exactly under the profile elements and the risk of inaccuracies in processing on the site is reduced. In addition, should be able to collect water in the connection area, so as to extend the life of the cladding considerably, with the fasteners are covered.

• dass das Profilelement eine an den Federbereich angrenzende erste Vertiefung einer Länge l₁ aufweist, wobei sich für das Profilelement eine Gesamthöhe h₁ ergibt,
• und dass die Länge b des Nutbereichs größer ist als die Länge a des Federbereichs, so dass bei der Verbindung zweier oder mehrerer Profilelemente der Federbereich und ein Teil der ersten Vertiefung durch den Nutbereich verdeckt ist.

To solve the problem, the profile element according to the invention is characterized by

• the profile element has a first depression of a length l ₁ adjoining the spring region, an overall height h ₁ being obtained for the profile element,
• and that the length b of the groove region is greater than the length a of the spring region, so that in the connection of two or more profile elements, the spring region and a part of the first depression is covered by the groove region.

If the profiled elements according to the invention are also worked from the bottom upwards and the fastening of the profiled element to the substructure or the building exterior wall is carried out with the spring directed upwards, the formation of water esters is prevented and corrosion in the area of the connecting means of the individual profiled elements is counteracted.

The area covered is preferably suitable for providing recesses, preferably in the form of bores, or deformations, preferably in the form of a bead, a grain or a marking.

The production of the base panel is preferably ensured by forming by means of folding machine, edge press or roll former, whereby non-ferrous metals can be used with a material thickness of 0.5 to 2.5 mm. After production of the base panel results in a Sichtflächenmaß of 350 mm. Two 140 mm wide panel panels are separated by a 40/20 mm joint. It was but not excluded that different materials are used, wherein the edge is provided at least on one side of a metal.

The resulting geometry achieves a panel-like appearance. The installation directions of the system are horizontal from bottom to top or vertical without directional specification, while "panel on panel" is inserted and fixed. This ensures that, in contrast to traditional tongue and groove systems, the panels are completely inserted and a levering or incomplete insertion is impossible.

The attachment is preferably carried out directly in pre-punched or drilled holes in the upper part of the panels by screws with sealing washer. Additional holders or followers are not necessary. By "placing" the next row of panels, the fastenings of the underlying row of panels are covered and thus are not visible. However, it is not excluded that a bonding of the panels takes place on a flat substrate.

It has been shown that sheet metal, in particular titanium-zinc sheet, can be used as the metallic material for producing the profile elements according to the invention. In order to keep the production costs as low as possible, it is advantageously possible to use sheet-like material of constant thickness. Due to the particular embodiment of the connecting means, tongue and groove, which are formed by edge edges of one and the same piece of sheet metal advantageously a thin sheet for the production of the profile elements according to the invention can be used.

The groove of the profile element according to the invention is equipped so that a joining and securing to thrust is achieved.

Advantageously, an optical coverage of the fasteners is achieved even when connecting a plurality of inventive profile elements, so that a visually appealing image of a facade can arise, which is not disturbed by fasteners. In addition, the fasteners are effectively protected from the weather in this way.

In accordance with the invention, it has been recognized that it is advantageous if not only the groove area is produced from the folded material of the profile element, but also when the spring can be produced by edging of the metallic material and then has a bent area. This advantageously allows thin sheet metal, e.g. be used with a sheet thickness of 0.5 to 2.5 mm, which has a reinforcement by the edging, so that a stable spring can be achieved even with thin sheet thicknesses.

To improve the weather resistance of the profile element or a facade cladding consisting of a plurality of profile elements, the groove portion may have at the one end of the profile element according to the invention an angled end piece, which serves to further protect the fastener and which is bent in the direction of the fastener. Furthermore, the optically uniform overall impression of the facade can be achieved with parallel recesses of the same width by the angled tail. This angled tail is also made by edging the metallic material. It has been shown that an angle of the end piece of approximately 130 ° with respect to the plane E is selected for optimal discharge of the rainwater.

In order to increase the bearing surface of the profile element according to the invention on the substructure or the building exterior wall, the invention provides for the profile element to be designed with at least one second recess between the groove area and the spring area. In addition to an enlarged bearing surface of the profile element here still a positive optical effect can be achieved, since due to the optical separation of the profile element into different individual areas a finer facade image can arise. The profile element according to the invention preferably has a second recess for this purpose.

Thus, the dimensions of the second wells in the overall appearance to the dimensions of the recess in the connection region of the profile element according to the invention fit, the invention provides that the second wells have a length l ₂ , which is smaller than the length l _{1 of} the first recess. Ideally, the length l _{2 is} selected such that after the assembly of a facade cladding from a plurality of the profile elements according to the invention, there is an optically uniform image of the individual recesses. In this case, both the second depressions and the regions of the first depressions covered by the groove region of a profile element are uniformly formed.

So that the water can run off in the best possible way even in the region of the depressions and no water seep form, it is advantageous if first and / or second depressions are trapezoidal in cross-section. Due to the sloping surfaces, an improved outflow of rainwater can be brought about. Preferably, the trapezoidal angle is 130 ° to the plane E of the base of the metallic material.

Advantageously, the recesses, which are suitable for the implementation of fastening means are designed as bores, which may have both round and square or oval or other shapes. As fasteners are particularly suitable screws or nails. It is also possible that the recesses are not provided as holes and have no opening (s). In this embodiment, it is possible to use so-called self-tapping screws or nails or staples, which are introduced directly through the profile element according to the invention in the substructure or the building exterior wall for attachment of the profile elements or. The placement of these or similar fasteners is facilitated by the visually or haptic recognizable deformations.

It has been found that the length l _{1 should be} 50 to 60 mm, preferably about 55 mm, and the length l _{2 should be} 35 to 45 mm, preferably about 40 mm. In this way, it can be achieved that the length l _{2 of} the second recesses in the case of connected profile elements is optically matched to the length l _{1 of} the first recess, so that a visually harmonious overall impression of the facade cladding can arise.

In order to obtain a sufficiently stable groove, it is advantageous if the groove has a depth t of 10 to 20 mm, preferably about 15 mm. Furthermore, it is advantageous if the groove has a width c of 1 to 3 mm, preferably about 2 mm. The length of the spring is also decisive for the rigidity or strength of the connection. Advantageously, the spring is 15 to 25 mm, preferably about 20 mm.

In order to create a visually appealing impression in the case of a façade consisting of the profiled elements according to the invention, it is advantageous if the height h _{1 of} the profiled element is 10 to 20 mm, preferably approximately 15 mm.

So that a particularly simple pushing together of the individual profile elements is possible, tongue and groove can run substantially parallel to the base and to the plane E.

To solve the problem, a cladding according to the invention of a plurality of profile elements characterized by the fact that the groove portion of a second profile element completely covers the spring portion and the recess of a first facade element when two or more profile elements are pushed into each other.

In this way it can be ensured that each connecting means is covered and creates a visually harmonious overall impression in the viewer of the facade cladding. It can also be ensured that an improved drainage of water from the facade can be done and the respective fasteners are optimally protected from the weather.

The invention also extends to the intended to a facade cladding attached and fastened profile elements.

It is possible to lay the individual profile elements horizontally or vertically on a substructure, so that a large-scale facade cladding arises. Furthermore, the profile elements can also be laid diagonally at any angle.
