Facade panel and building facade

Abstract

With a façade panel, with a front and a rear that can be aligned to a building, and with edges running vertically and horizontally, limiting the façade panel, the invention proposes with recesses arranged on a line running vertically, whereby the line runs parallel to a vertical edge of the façade panel on the rear.

Description

The invention relates to a façade panel according to the preamble of claim 1 and a building façade according to the preamble of claim 6.

Building façades and the corresponding façade panels are known from practice. The majority of façade panels are embodied in a rectangular manner, thus provided with edges running exclusively horizontally and vertically. The joint-aligned alignment of the façade panel, i.e., with aligned joints and always the same joint width, can often be ensured only with great mechanical effort, since the associated mounting construction by means of which the façade panels are held onto the building usually allows a certain mobility and free positioning capability of the respective façade panel in its provided installation site for equalizing tolerances. Joint profiles are therefore often used, i.e., extruded profiles of metal or plastic which are inserted in the joints. A joint running smoothly between the façade panels is ensured by placing the adjacent façade panels against this joint profile. However, the architects' freedom of design in the embodiment of the building façade is adversely affected by this.

The object of the invention is to disclose a façade panel and a building façade which respectively render possible an exact joint course between the individual façade panels with as great as possible freedom of design of the façade.

This object is attained through a façade panel with the features of claim 1 and through a building façade with the features of claim 6.

In other words, the invention proposes creating an “invisible” guide system, i.e., provided on the rear of the façade panel, which renders possible the correct vertical alignment of several façade panels one above the other or of two laterally adjacent façade panels next to one another, thus ensuring the desired vertical joint courses. Since this guide system is provided on the rear of the façade panels, no profiles projecting into the joints are necessary which would restrict the design of the joints and thus the freedom of design of the building façade.

For the vertical alignment of the façade panel at least two recesses are provided which are provided at a distance one above the other on the rear of the façade panel and which lie on a line that runs parallel to the lateral vertical edge of the façade panel. A vertical alignment of the façade panel or its lateral edge is rendered possible through corresponding projections which are provided on the mounting construction and which extend into these recesses. A vertical alignment of the opposite lateral edge is also automatically ensured through this so that in all a very regular and homogenous joint image can be achieved without auxiliary means visible from the outside. Since the mounting construction, normally a metallic support construction, can be produced with great precision, the attachment of such projections to the mounting construction can also be made with great precision so that a correct and exact positioning of the individual façade panels is possible by means of the projections, while the actual attachment method of the façade panels to the mounting construction still provides a certain mobility of the attachment elements for equalizing tolerances which makes it possible to align the attachment elements according to the specific conditions of the façade panels.

In order to be able to compensate for irregularities than can occur during the production process of the façade panels, it can preferably be provided not to make the recesses in the façade panel until afterwards, thus at the end of the actual production process. For example, if the façade panels are made of clay or a similar material which is fired for hardening, influencing the geometry of these façade panels through the firing process cannot be ruled out. If the recesses are not made in the rear of the façade panel until after the firing process, it can be ensured that these recesses are arranged with the desired precision which, together with the accurate, defined alignment of the projections in the area of the mounting construction, later ensures the desired positionally accurate arrangement of the façade panel on the building.

In particular if the façade panel is embodied as a corner panel, thus features a mitered vertical corner edge, the positioning and alignment of the façade panel according to the proposal by means of the recesses on the façade panel and the projections on the mounting construction provides a solution to existing problems which hitherto could be solved at best with the aid of often undesirable joint profiles so that the embodiment according to the proposal is particularly advantageous with such corner panels.

The recesses can be embodied as individual bores, slotted holes or the like. However, it can be provided particularly simply in terms of production technology to combine these recesses into a through groove. This renders possible in a particularly economic manner the use of corresponding profiles which are attached to the mounting construction and which feature a flank that extends into the recess of the façade panel or several façade panels. For example, simple, commercial and economical L-shaped angle profiles can be used which are attached by their one flank to the mounting construction and extend with the other flank into the groove-shaped recess of the façade panel. Although a desired precise lateral guidance of the façade panel is given through the continuous geometry of the groove which is not linked to specific points on the one hand and of the L-shaped angle profile on the other hand, great scope is given in the attachment in terms of height of the angle profile or the alignment in terms of height of the façade panel, however, so that an uncomplicated and rapid mounting is supported.

In order to be able to easily absorb thermal expansions or shocks from seismic causes, preferably only a single line provided with recesses can be provided on the rear of the façade panel so that the façade panel can work freely on both sides of this line under the given influences and, e.g., can expand, vibrate or the like. If the line with the recesses runs near a vertical edge, this edge is described as “provided with recesses.” As with a component fixed on one side, this edge of the façade panel can be regarded as a ‘fixed bearing” whereas the opposite edge can be seen as a “loose bearing” which, although it is attached to the mounting construction, can work and conform to the seismic or thermal conditions due to the above-mentioned tolerances and mobilities with this type of attachment so that the façade panel can, e.g., expand or contract.

Exemplary embodiments of the invention are explained in more detail on the basis of the purely diagrammatic drawings. They show:

FIG. 1 A horizontal cross section through the corner embodiment of a building façade,

FIG. 2 A horizontal cross section through a column or support cladding, and

FIG. 3 A second exemplary embodiment of a corner embodiment of a façade construction.

In the drawings 1 respectively designates a façade panel which is attached to a mounting construction labeled as a whole with 2, whereby the mounting construction 2 in turn is attached to a building that is not shown for reasons of clarity.

In FIG. 1 the mounting construction 2 features an angle bracket 3 attached to the building. A hollow profile 4 with a roughly square cross section extends from the angle bracket 3, whereby this hollow profile 4 can be formed by a single or two separate, approximately Z-shaped profiles. The hollow profile 4 can be embodied as a continuous extruded profile or as a plurality of supports arranged spaced one above the other which respectively feature only a limited height of, e.g., 5 cm or 10 cm. A spacer profile arrangement is labeled as a whole with 5. A spacer profile with damping material properties, e.g., of EPDM, is used in a manner known per se for the vibration-damping mounting of the façade panel 1 to the remaining mounting construction 2.

Attachment elements 10 are provided on the hollow profile, which attachment elements can be seen in particular from FIGS. 2 and 3 and which hold the façade panels 1 in a manner known per se. They are embodied, e.g., as J-shaped or U-shaped holders which wrap around the façade edges, in that they extend, e.g., under the façade panel 1 and engage in a groove running on the panel lower edge.

In addition, an L-shaped angular profile 6 is provided on the mounting construction 2 which on the one hand is attached to the mounting construction 2 and which on the other hand extends with both ends of its two flanks into respectively one groove 7 of respectively one façade panel 1 so that these two adjacent façade panels 1 embody between them a defined joint of equal width over the entire height of the façade panel 1.

If the angular profile 6 also extends over the height of the façade panel 1 shown to the next higher façade panel or that arranged under it, the aligned alignment of the joints of façade panels 1 arranged one above the other is ensured by this construction.

FIG. 2 shows that the façade panels 1 can be embodied not only on one vertical edge as corner panel, thus that not only one vertical edge is mitered as a corner edge; instead in the case of small-sized façades, such as, e.g., the cladding of a support construction, it can be provided that one or more of the façade panels used forms corner edges on both opposite vertical edges.

With the center façade panel 1 shown in FIG. 1, it is furthermore provided that the groove does not run closely adjacent to a certain corner edge, but the groove 7 runs at the center of the façade panel 1 so that in the case of changes in the geometry of the façade panel 1, e.g., due to thermal influences, an identical change of the joint width will occur on both joints of the façade panel 1 and thus an identical joint image is achieved. In contrast, the two façade panels 1 shown at the side in FIG. 1 are provided with a groove 7 near a single edge, as shown in FIG. 1.

FIG. 3 shows an exemplary embodiment of a corner embodiment of the building façade with a mounting construction 2 embodied differently compared to FIG. 1, which construction, i.a., features a mounting angle 8 starting from which an arm 9 with multiple offsets extends which in turn supports the two façade panels 1.
