1. Field of the Invention
The invention relates to a facade 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. Further, the invention relates to a building facade with façade panels and with a mounting construction for attaching the façade panels to the building.
2. Discussion of Background Information
Building facades 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 present invention provides a façade panel and a building façade that can render an exact joint course between the individual façade panels, resulting in the greatest possible freedom of design of the façade.
According to an embodiment of the invention, the façade panel can include recesses arranged on a line running vertically, whereby the line runs parallel to a vertical edge of the façade panel on the rear. According to another embodiment, the building façade may include two horizontally adjacent façade panels parallel to their two vertical adjacent edges featuring recesses on the rear sides directed toward the building. The recesses are respectively arranged on a line that runs parallel to a vertical edge of the respective façade panel, and projections are provided on the mounting construction, which projections extend into the recesses such that the façade panels are aligned exactly parallel to one another.
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 the above mentioned 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.
According to the invention, an embodiment can include for the vertical alignment of the façade panel at least two recesses which are provided at a distance one above the other on the rear of the façade panel. The at least two recesses lie on a line that runs parallel to the lateral vertical edge of the façade panel. Further, a vertical alignment of the façade panel or its lateral edge can be 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 can also be automatically ensured through the above arrangement, so that in all, a very regular and homogenous joint image can be achieved without auxiliary structure visible from the outside. Since the mounting construction, e.g., a metallic support construction, can be produced with great precision, the attachment of the projections to the mounting construction can also be made with great precision. In particular, the arrangement of the projections makes it possible for the correct and exact positioning of the individual façade panels. Also, the actual attachment method of the façade panels to the mounting construction 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 that can occur during the production process of the façade panels, the recesses in the façade panel can be made at the end of the production process. For example, if the façade panels are made of clay or a similar material, it possible during the firing or hardening process, the geometry of the façade panels could be influenced which could cause irregularities. Further, 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. Furthermore, with the precisely arranged recesses and the accurately aligned projections in the area of the mounting construction, together provide the desired positionally accurate arrangement of the façade panel on the building.
In particular, if the façade panel is embodied as a corner panel, e.g., a mitered vertical corner edge, the positioning and alignment of the façade panel via the recesses on the façade panel and the projections on the mounting construction provides a solution to existing problems over the current industry practices, such as the use of undesirable joint profiles. Thus, the present invention is particularly advantageous with such corner panels.
The recesses can be embodied as individual bores, slotted holes or the like. However, in terms of production technology, it may be economically advantageous for the recesses to be combined into a through groove. Which, could allow for the use of the corresponding profiles 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 of the L-shaped angle profile. 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), so that an uncomplicated and rapid mounting can be supported.
In order to be able to easily absorb thermal expansions or shocks from seismic causes, it is possible a single line provided with recesses can be provided on the rear of the façade panel. This allows the façade panel to be able to 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.
The present invention is further described in the detailed description which follows, in reference to the noted plurality of drawings, in which like reference numerals represent similar parts throughout the several views of the drawings, and wherein:
According to an embodiment of the invention,
In addition, an L-shaped angular profile 6 can be provided on the mounting construction 2 which may be attachable to the mounting construction 2 and extend with both ends of its two flanks into one groove 7 of the one façade panel 1. Further, so that these two adjacent façade panels 1 embodied between them, provide for a defined joint of equal width over the entire height of the façade panel 1.
According to an embodiment of the invention, it possible to ensure the alignment of the joints of the façade panels 1 by the above noted construction, even if the angular profile 6 extends over the height of the façade panel as shown next to the higher façade panel or if the angular profile 6 is arranged under the height of the façade panel as shown next to the lower façade panel.

Further, the center façade panel 1 shows the groove which does not run closely adjacent to a certain corner edge, but the groove 7 runs at the center of the façade panel 1. (See
